    METHOD AND APPARATUS FOR MANUFACTURING A BUILDING ELEMENT AND BUILDING ELEMENT
    Object of the invention
    The invention relates to a method for manufacturing a building element used in a corner of a building. The invention further relates to an apparatus for making such a building element. The invention further relates to such a building element. The invention further relates to the use of an accessory 10 with a flat casting table for manufacturing a building element used at an angle.
    Background of the Invention
    It is known to use sandwich panels in the construction of buildings. Such elements comprise a planar outer shell, a planar inner shell and a layer of dielectric material interposed therebetween. As the insulating material, a heat-insulating material known per se can be used. Exterior and interior shells can be made, for example, by casting 20 concrete or the like.
    As is known, the exterior walls of buildings comprise angles, most typically angles that are straight angles. Such angles can be made, for example, by positioning the two above-described sandwich elements perpendicular to one another and filling the space between the elements appropriately and with a suitable sealant. If possible, the dimensioning of the inner shell of the element or elements should be slightly modified to suit the angle. An example of such a structure is given in the VTT Research Report VTT-R-07901-11 (Figure 11).
    However, there are some problems with the prior art. One problem is how to maintain substantially planar elements during construction. For example, when constructing an angle, the sealant is typically not robust enough to join the two perpendicular elements 35 so that the angle elements remain upright without additional support. Various additional subsidies significantly slow down construction and thus increase costs.
    20195038 prh 23 -01- 2019
    Thus, for reasons of cost, modern construction often aims to reduce corners of the building. This, in turn, may lead to structural solutions that are not optimal for the use of space in the construction industry and may lead to wasted space in the building.
    In addition, because it is difficult to hold planar elements, the height of the elements typically corresponds to one room height, whereby po. The height is, for example, about 2.5 m to 3.5 m. In this case, when constructing two or more storeys, each storey is built separately on top of each other, which slows down the erection of a two or more storey building.
    BRIEF SUMMARY OF THE INVENTION
    The problems described above can be reduced by using a building element suitable for the corner of the building. Such an angle element is disclosed in claim 10. Such an angle element can be manufactured, for example, by sliding casting. Method po. The method for producing the element is set forth in claim 1. The method may advantageously be implemented by means of a device therefor. Such a device is claimed
    The device may also be implemented in an existing flat casting accessory according to claim 5. Such an accessory may be used with a flat casting table to produce the aforementioned building element as set forth in claim 12.
    Since the building element is molded and comprises two planar portions arranged at an angle to each other, said building element itself remains upright on a flat surface. This greatly simplifies construction. The elements may be secured to one another or to similar angular elements 30, for example by welding. Such an element may also be clearly higher than the normal room height, for example two room heights. These factors significantly speed up the erection of the building.

    Detailed Description of Embodiments
    20195038 prh 23 -01- 2019
    Figure 1 shows a building element 100 according to one embodiment.
    The building element 100 is shown in the position in which it is manufactured according to one embodiment. In Figure 1, the directions Sx and Sy are horizontal and the direction Sz is vertical. The building element 100 has a continuous profile in the longitudinal direction Sy. For example, the building element 100 may be used to construct a wall in which said longitudinal direction Sy of the building element 100 would be vertical. Also in the other figures 30, the directions Sx and Sy are horizontally perpendicular to each other and Sz to the vertical. Figures 3, 4, 6, and 7 show a manufacturing process and / or apparatus po. for making the building element 100.
    As used herein, the term "" direction is planar "means that po. direction is po. parallel to the plane in any direction; that is, po. level
    20195038 prh 23 -01-20199 consists of two points such that po. the direction is parallel to the segment between the two points. The expression '' plane parallel to the surface (or part) 'means a plane having the same normal as po. on the surface (or part). In this specification, the term is used only in relation to planar surfaces (or parts) 5. Unlike the surface itself (or part), po. the level continues over a wider area. The expression "" in the plane direction "means" in the direction parallel to the plane ". What has been said above about "direction is plane" also applies to "which (i.e. direction) is plane". The description also uses plane and surface normals, which are obvious concepts to the enlightened reader.
    By building element 100 is meant an element which can be used to construct walls of a building, especially exterior walls. A building is a building the interior of which is thermally insulated from its surroundings 15, in particular a residential building.
    The building element 100 of Figure 1 comprises an outer shell 110 and an inner shell 120. In Figure 1, the outer shell 110 has a continuous L-shape. The outer shell 110 is seamless. Also, the inner shell 120 may be seamless. The outer casing and inner casing 20 can be made by casting as described below. The outer shell 110 and inner shell 120 of the picture building element 100 are made by casting. The inner and outer shell can be made of the same material. The outer shell 110 may comprise cement. For example, exterior shell 110 may comprise concrete comprising cement. Further, the outer shell 110 may be reinforced to reinforce the outer shell in a manner known per se. What is said here about the material and reinforcement of the outer shell 110 also applies to the material and reinforcement of the inner shell 120.
    The thickness du and / or di 2 of the outer casing 110 may be, for example, at least 40 mm or 30 at least 50 mm. The outer shell thickness du and / or di 2 may be up to 200 mm or up to 150 mm, for example. The thickness du and / or di 2 of the outer casing 110 may be, for example, 70 mm to 110 mm, such as 80 mm to 100 mm.
    For example, the inner shell thickness d2i and / or d22 may be at least 40 mm or at least 50 mm. For example, the inner shell thickness d2i and / or d22 may be 35 up to 250 mm or up to 200 mm. The thickness d2i and / or d22 of the inner casing 120 may be, for example, 110 mm to 190 mm, such as 130 mm to 170 mm.
    20195038 prh 23 -01- 2019
    The building element 100 further comprises a heat insulating core 130. The heat insulating core 130 comprises a suitable heat insulating material such as polyurethane (PU), mineral wool, or polystyrene (expanded polystyrene, EPS, or extruded polystyrene, XPS). The heat-insulating material 5 preferably has a thermal conductivity of at most 0.05 W / mK or at most 0.04 W / mK. The thermal conductivity can be determined, for example, as in EN 12667.
    The thickness d3i and / or d32 of the heat insulating core 130 is preferably at least 10,100 mm, such as at least 150 mm. For example, the thickness d3i and / or d32 of the heat insulating core 130 may be up to 500 mm, such as up to 400 mm. The thickness d3i and / or d32 of the core 130 may be, for example, 120 mm to 200 mm, such as 140 mm to 180 mm. Here, the thickness may refer to the thickness d3i of the first insulating part 132 and / or the thickness d32 of the second insulating part 134. The first insulating part 132 may have the same thickness as the second insulating part 134 (i.e. d3i = d32). The insulation thickness required will depend on the materials used and the desired energy efficiency. A distance corresponding to said thickness remains between outer casing 110 and inner casing 120. Through the core 130, traps known per se, such as a stub or a diagonal bar, may be provided for attaching the outer shell 20 110 to the inner shell 120.
    The building element 100 is preferably provided with lifting loops 160, as shown in Figure 1, to lift the building element, for example, from the manufacturing device 200 to the storage. The building element 100 may comprise second lifting loops 165 to lift the element 100 at the construction site. In the construction phase, the lifting loops 160, 165 can be removed, for example, by sawing. As described below, the lifting loops 160, 165 on different sides of element 100 can be used at different stages of the process. Therefore, the element 100 of Figure 1 comprises a first lifting loop (preferably at least two lifting loops) 30 on its first side and a second lifting loop (preferably at least two lifting links) on its second side such that the first side normal and the second side normal are perpendicular. Preferably, in addition, said sides are such that the first portions 112,132, 122 of element 100 have a thickness parallel to both the first and second sides.
    20195038 prh 23 -01- 2019
    The outer casing 110 comprises a planar first outer portion 112 and a planar second outer portion 114. The first 112 and second 114 portions meet each other such that an angle or a rounded angle is formed between said portions 112, 114, as described below. The outer casing 110 is made by casting, so that it is a uniform, i.e. seamless, piece. As to where the first part 112 changes to the second part 114, reference is made to Figure 1 and what is hereinafter referred to as the width of the parts.
    The inner casing 120 comprises a planar first inner member 122 and a planar 10 second inner member 124. The inner casing 120 may be made by casting. If so, the inner casing 120 is an integral, i.e. seamless, piece.
    As shown, the cross-section of the outer shell 110 in the plane perpendicular to the longitudinal direction Sy of the element 100 is open. Thus, it is not closed, as would be the case with a pipe. The same applies to the inner casing 120.
    In the embodiments shown in the figures, the outer shell 110 comprises only two planar portions 112, 114. In other words, the normal N12 (Fig. 2) in the plane parallel to the second outer portion 114 pierces either (a) only said second outer portion 114 or (b) a second outer part 114 and said first outer part 112 - depending on the angle between the parts 112 and 114.
    Correspondingly, the inner casing 120 comprises only two planar portions 122, 124.
    The building element is preferably dimensioned such that its length L (see Fig. 1) corresponds to at least one room height, i.e. L is at least 2500 mm.
    Preferably, the length L corresponds to at least two room heights, i.e. at least 6500 mm. For example, the length L can be up to 11 m. Preferably, the length is between 6700 mm and 7000 mm.
    The width W1 30 of the first part 112 of the outer shell 110 of the building element 100 is preferably at least 1200 mm, at least 1800 mm or at least 2400 mm.
    The first part 112 of the outer shell 110 of the building element 100 preferably has a width W1 of not more than 6000 mm, not more than 4800 mm or not more than 3600 mm. Preferably, the width W1 is 3000 mm to one digit accuracy.
    The width W2 of the second part 114 of the outer shell 110 of the building element 100 (i.e. the width without the thickness du of the first part) is that of the first parts 132,
    20195038 prh 23 -01- 2019
    122 common thickness cb + chi greater. Preferably said width W2 is at least 450 mm or at least 600 mm. Said width W2 is preferably at least 300 mm greater than the common thickness d2i + d3i of the first portions 132, 122. The width du of the second part 114 of the outer shell 110 of the building element 100 including the thickness du, i.e. dn + W2, of the first part 112 is preferably not more than 2400 mm, not more than 1800 mm or not more than 1200 mm. Preferably, the width dn + W2 is 900 mm to one digit accuracy.
    Figure 2 is a front view of a building element 100. As shown in FIG. 10, in one embodiment, the normal Nn in the plane of the first outer portion 112 facing the first inner portion 122 is substantially parallel to the normal N21 of the plane in the first inner portion 122 which extends away from the first outer portion 112. In the embodiment of FIG. the second outer portion 15 114 being substantially parallel to the second inner portion 124 in a manner similar to that of the first portions 112, 122 above.
    As shown in Figure 2, in one embodiment, the core 130 comprises a planar first dielectric portion 132 which is sandwiched between the first outer portion 112 and the first inner portion 122. Further, the core comprises a planar second dielectric portion 134 which is sandwiched between the second outer portion 114 and the second inner portion 124.
    The building element 100 shown in Figure 2 is of the angular type.
    The outer shell 110 then forms an angle or a rounded corner. As shown in Figure 2, the normal Nn in the plane of the first outer portion 112 of the outer shell 110 forms an angle α1 with the normal N12 of the second outer portion 114. Said normal of planes are considered to be normal toward the inner casing 120. In the case of a corner element, said angle α1 is at least 30 degrees and at most 150 degrees.
    Preferably, the angle α1 is at least 45 degrees and at most 135 degrees. More preferably, the angle α1 is at least 60 degrees and at most 120 degrees, such as about 90 degrees (to one digit). As shown in Fig. 8, said angle α 1 and the angle β between outer portions 112, 114 are interdependent. As can be seen in Figure 8, β + α 1 = 180 °. Preferably, the angle β is straight 35 or obtuse, i.e. at least 90 degrees (to one significant digit).
    20195038 prh 23 -01- 2019
    Correspondingly, preferably, the angle α 1 is straight or sharp, i.e. not more than 90 degrees (to one significant digit).
    As shown in Figures 1 and 2, no sealant 5 remains between outer shell 110 and inner shell 120, unlike many known angular solutions. As shown in Figure 1, there is no material between the outer casing 110 and the inner casing 120 from which the outer casing 110 or inner casing is molded. Preferably, the first portion 132 and the second portion 134 of core 130 are integral, and there is no gap between these portions 132, 134, or a gap having a width of 10 to 10 mm or 5 mm or less. Preferably, the core portions 132 and 134 are connected as closely as possible to each other.
    It has been found that outer shell 110 can be made by casting. The inner shell 120 may also be made by casting. For this purpose, 15 suitable casting devices 200 or accessories 200, such as a table 200 (see fig.
    Figure 3), or a flat casting table accessory.
    The outer casing 110 may be molded such that the outer casing portions 112 and 114 cure simultaneously; i.e., at one first moment portions 20 112 and 114 are uncured and at a later moment portions 112, 114 are cured. Also, the inner shell may be molded such that the inner shell portions 122 and 124 simultaneously cure. Preferably, the outer and inner shells 110, 120 are molded such that the outer and inner shell portions 112, 114, 122, 124 cure simultaneously; i.e., at one of the first 25 moments, all of said parts 112, 114, 122, 124 are non-cured and at a later moment all said parts 112, 114, 122, 124 are cured.
    In one embodiment of the manufacturing method, the planar first outer portion 112 of the outer shell 110 of the building element 100 is molded horizontally. Horizontal casting has the technical advantage that the first part 122 of the inner shell 120 to be cast later does not need to be separately supported, but is naturally positioned in the correct position.
    If the element 100, such as the first outer part 112, is to be provided with an opening for a window or door, such an area may be delimited by boards, boards, and / or
    20195038 prh 23 -01-20199 in various ways known per se. By delimiting the area, the material to be cast can be prevented from entering said opening, whereby the finished element 100 comprises such an opening.
    Then, at least partially, a core 130 is provided on top of the first outer portion 112 comprising a planar first dielectric portion 132 and a planar second dielectric portion 134. The first dielectric portion 132 is substantially parallel to the first outer portion 112. Figure 3) are substantially parallel.
    The first insulating part 132 comprises a first end 132a and a second second end 132b opposed in the plane of the first insulating part 132 (Fig. 3b). The second insulating part 134 comprises a first end 134a and a second opposite end 134b in the plane of the second insulating part 134. The first end 134a of the second insulating part 134 is connected to the first insulating part 132, preferably to its first end 132a. The core 130 may be partially disposed on the first outer portion 112 in a single piece, or the parts 132, 134 of the core 130 may be provided separately. Parts 132, 134 may be joined together. The joining may take place before or after the first insulating part 132 is placed on the first outer part 112. The entire core 130 may be disposed over the first outer portion 112 (see Figure 3), or if the angle α1 is small (see Figure 8), only a portion of the core 130 will remain over the first outer portion 112.
    Normal N31 in the plane parallel to the first dielectric portion 132 forms an angle 0C3 with the plane N2 in the second dielectric portion 134. Said normal N31 plane parallel to the first dielectric portion 132 faces away from the (already molded) first outer portion 112. The normal N32 plane dorsal to the second dielectric portion 134 faces away from the second outer dept 114 (which will be cast). The angle 0C3 may be suitably selected with respect to the corresponding angle α1 of the dielectric element, for example substantially the same. These angles are shown above.
    Preferably, the core 130 is further disposed so that the first outer portion 112 extends in at least one direction of its plane over the first end 132a of said first dielectric portion 132. This occurs at the point designated Y in Figure 3 35. Alternatively, this portion of the first outer portion 112 may be subsequently cast when the second outer portion 114 is cast.
    20195038 prh 23 -01- 2019
    The core 130 thus arranged is supported in a plane parallel to the first outer portion 112 to hold the core 130 in this direction (typically horizontal). This direction is furthermore the one of the planar directions of the first outer portion 112 with which the normal 5-plane plane of the second dielectric portion 134 has the smallest angle. The core is supported in this direction by a piece of solid material. Preferably, the core 130 is supported at said second end 132b of the first dielectric portion to hold the core horizontally. Preferably, the first insulating part is thus supported towards a plane 10 parallel to the second insulating part 134. The corresponding device comprises means 240 arranged during manufacture of the building element 100 to support the core 130 of the building element 100 in the direction of the plane of the first outer part 112 of the building element 100. The support may be implemented with a longitudinal mold 240 as shown in Figure 3.
    Further, the core 130 is supported by applying a force directed toward the plane parallel to the first outer portion 112. Preferably, the force is applied by means of a body made of solid material, such as a press 242. This has the effect that, since the core 130 would naturally float over the molded part 112, when casting the part 114, at least a portion of the material 20 of the molded part would tend to thicken the first outer part 112 if no such support was provided. In other words, the material to be cast could flow under the core 130. Preferably, the core is supported from the second dielectric portion 134 toward a plane parallel to the first outer portion 112. Referring to Figure 3, 25, the core 130 may be supported, for example, from said second end 134b of the second insulating part 134, for example by a press 242. The already molded first outer part 112 and supported ends 132b and 134b will lock the core 130 in place. With the core 130 thus locked, other portions of the outer and inner shells of element 100 may be cast.
    Further, the first portion 132 of the core 130 may be supported by the support 140. The support 140 may be supported, for example, on the surface 210 of the mold 211. The support 140 may comprise a flange 141 or a corresponding core 130. The support 140 may be somewhat wide in shape, such as a brick or the like (not shown).
    Preferably, the support 140 is stainless. The end 140 of the support 140 towards the surface 210 may be sharpened so that only a very small portion of the support 140 remains visible on the element
    20195038 prh 23 -01- 2019 tin 100 on outer surface 110 of outer casing. The support 140, in particular in combination with the support force for the plane parallel to the part 112 towards the core 130 mentioned above, further locks the core at a suitable position during casting.
    In addition, or alternatively, the second dielectric portion 134 may be supported, for example, on a second surface 220 or a surface 264 of an inner mold 260 in the same manner as the first portion may be supported by a dock 140. Further or alternatively, the core 130 may be supported from its first portion 132 to the inner mold 260.
    In one embodiment, said planar first outer portion 112 is horizontal and / or said planar first outer portion 112 is non-curing, the planar first inner portion 122 of the inner member 120 of building element 100 being horizontal over a planar first insulating portion 132.
    In one embodiment, said planar first exterior portion 112 is horizontally molded with a planar second exterior portion 114 of building element 100. In this embodiment or in another embodiment, said planar first exterior portion 112 is uncured, molded second exterior shell 110 of building element 100 .
    In one embodiment, said planar first interior 122 is horizontally molded with a planar second interior 124 of a building element interior casing 120. In this or another embodiment, said planar first interior 122 is uncured by casting a planar second interior 124 of a building element interior casing 120.
    As stated above, preferably, the outer shell 110 is molded as a slip cast. Sliding casting refers to continuous casting so that there is no boundary between the drying and the fresh material, such as concrete. The slip casting outer shell 110 (or inner shell 120) thus does not include seams formed during the casting process. Preferably also an inner shell
    120 is cast as sliding casting. As the inner casing 120 is molded, its first interior 122 may be partially cured when its second interior 124 is initiated
    20195038 prh 23 -01- 2019 whale. This prevents material from the second insert 124 from leaking into the casting area of the first insert. Further, the casting of the second inner member 124 (and optionally the second outer member 114) may be timed such that (i) the viscosity of the molded material is sufficient to hold the shape of the molded material and (ii) no seams are formed on the other outer members 5114, 124. Seams would be formed if non-cured material was cast over the fully cured material. Such timing is well known to those skilled in the art for the principles of sliding casting. For example, the casting rate of the second sections 114, 124 can be selected using these principles to suit. Naturally, even the smallest viscosity 10 of the first portions 112, 122 is sufficient when the height of the partially cast second portions 114, 124 is small. Similarly, when the second portions 114, 124 are molded at a suitable rate, the viscosity of the already cast portions increases, preventing the uncured casting material from moving too much downwards.
    Said second portions 114, 124 can be cast in portions and alternately, whereby the molten material, such as concrete, does not exert excessive forces on the other portion 134 of the core only from one side of the core. Said second portions 114, 124 may be vertical, or the normal of planes parallel thereto may form, for example, an angle of up to 60 degrees with a horizontal direction.
    With this angle, the aforementioned angle cm of the building element can be suitably selected; for example, the boundaries previously presented. Said second portions 114, 124 are molded such that one insulating portion 134 remains between the second outer portion 114 and the second inner portion 124. Further, the second outer portion 114 is molded such that between the normal levels of the planes parallel to the first outer portion 112 and the second outer portion 114, the above angle ai is maintained.
    The casting area of the second outer portion 114 is delimited by one surface 220 (i.e., the second surface 220 of the device 200) and the second portion 134 of the core 130. The casting region 30 of the second inner portion 124 is delimited by the second portion 134 of the core 130 and the surface 264.
    Further, these casting areas may be delimited by an end mold 250 as shown in Figure 7.
    After manufacture, the inner mold 260 may be removed from the building element, or it may remain as a supporting structure for the building element 100. Such an inner mold 35,260, i.e. a support structure, may, for example, have a cross-section of 200 mm χ
    200 mm metal beam, such as steel beam. If the inside mold 260 does not remain part
    20195038 prh 23 -01-20199 building element, the same inner mold can be used to cast several building elements 100. It is possible that two inner molds 260 are used, for example overlapping, one of which, for example the lower one, remains part of the building element 100 and the second one, for example the upper one, is reused.
    The first core portion 132 may be secured to the second core portion 134 by means of an engaging means 144 (Figs. 2 and 3), such as a rod, for example a threaded rod. The rod may comprise, for example, metal or plastic. The fastener 144 may be supported at one end by a support 140 such as a plastic bar, metal bar, pre-cast concrete block or brick. The fastener 144 and the support 140 may be part of the same integral body. This piece may further include a flange 141.
    The support 140 may be placed on a substrate such as surface 210 (i.e., the first surface of device 200) such that it remains at a suitable position when casting the first outer portion 112. For example, a suitable location may be closer to first end 132a of first insulating member 132 than second end 132b. For example, a suitable point may be such that at least a portion of the plane 20 passing through the support 140 and parallel to the second outer portion 114 is disposed between the second outer portion 114 and the second inner portion 124. arranged on a pole or carpet. Such a bar or carpet may further comprise other earnings. The first dielectric portion 132 may be supported by a plurality of supports 140, which may be provided at positions 25 which vary in direction 210 of the surface.
    The corresponding building element 100 comprises a support 140. The support may be arranged at a suitable position as described above. The support extends from the outer surface of the building element 100 to the core 130. Furthermore, the support 140 is not made by molding said first outer member 112, leaving an interface 142 between said support 140 and the first outer member 112 (Figure 2). The support is preferably stainless as part of it may be in contact with outdoor air in the building. If the fastener 144 is used, the building element 100 comprises a fastener 144 arranged to fasten the first dielectric member 132 35 to the second dielectric member 134. The fastener 144 may extend from said support 140 through the first dielectric member 132 to the second dielectric member 134.

    In one embodiment of the method, the inner surface of the first inner portion 122 of the inner casing 120 is flattened, i. face up. For example, the smoothing may be performed with the first inner member 122 uncured. Referring to Fig. 4, suitable means 5, such as a trigger beam and / or a brush beam, may be used for leveling.
    In one embodiment, a metal welding element 150 (Figure 2) is attached to the building element 100, which allows the element 100 to be welded to the welding element 150 of the other element (second corner element 100 or ordinary 10 planar sandwich element) to form a building wall. Similarly, a building element 100 comprises a metallic welding element 150. In one embodiment, a lifting ring 160, 165 is attached to the building element 100. The attachment may be made during casting, i.e. when the outer and inner shells are still hardened15.
    In order to reinforce the building element 100, a supporting structure may be cast into the building element 100. Such a supporting structure connects the outer shell 110 to the inner shell 120. Such a supporting structure may, for example, be located 20 towards the ground in the building, whereby no particularly good thermal insulation is required at this point.
    It is clear that at such a point the building element does not comprise a heat insulating core in the sense described above. For example, the thermal conductivity of concrete is typically of the order of 2 W / mK. Thus, such a support structure can be cast, for example, on one edge 25 of the building element 100 corresponding to an end mold 250 (Fig. 7). For example, the support structure may be molded using a core 130 shorter than the length L of the element (Figure 1), whereby the core-free region may be completely molded.
    In a known manner, coating material 30 may be provided on the building element 100 during casting. Coating material is material that is not cast simultaneously with the building element. The coating material may be, for example, stone, such as slate or slate, or brick. For example, the coating material may be placed on the first surface 210, after which the first outer portion 112 of the outer casing may be molded, for example, on the coating material 35. The coating material may also be used on another surface 220.

    The method of manufacturing the building element described above can be carried out, for example, using a device 200 suitable for this purpose, such as a table 200 or an accessory for a flat casting table. The device 200 may be arranged in a position for removing the building element, where the completed building element 5 100 is more easily removed from the device and the device 200 can be more easily transported to its place of use. The device 200 can be arranged at least in the operating position. The device 200 can be assembled using, for example, an accessory kit which is suitable for use with a known flat casting table.
    The device 200 according to the invention can be seen as such an accessory as in claim 5 or as a whole as in claim 6. Some features of a flat casting table are set forth in claim 5.
    Figures 3, 4, 6 and 7 show devices according to some embodiments 200 in their operating position.
    The device 200 of Figure 3 in its shown operating position comprises a first planar surface 210 which, for example, is substantially parallel to the horizontal plane Sx, Sy in the operating position of the device. The device 200 also comprises a second planar surface 220. The second surface 220 is arranged with respect to the first surface 20 210 such that one normal Ns of the second surface 220 forms an angle of at least 30 degrees with a normal N4 of the first surface 210, e.g. .
    Thus, one of the normal ones here means the two normal ones of the surface which form a smaller angle with upward vertical + Sz. For example, the first surface 210 may be the upper surface of the first portion 211 of the outer mold. For example, the second surface 220 may be the surface of the second portion 221 of the outer mold; for example, an upper surface or a surface facing the first surface 210. Figures 8 illustrate the relationship between the angles β between surfaces 210, 220 and the normal angles 30 of portions 112, 114 of the outer casing 110. As shown in Fig. 8, said angle α1 and surfaces 210,
    The angle β between 220 depends on each other: β + ai = 180 °.
    As shown in Figure 3, said first surface 210 delimits an area in which the outer shell 110 of the building element 100, or the first portion 112 thereof, can be cast, i.e., a casting area. The area is further delimited by a second surface 220, a plate 245 (Fig. 5), or a mold used for rounding the outer corner. More generally the first
    20195038 prh 23 -01-20199 At the intersection of the plane 210 with the surface 210 and the plane 220 with the other surface 220, the die may be delimited by a suitable die delimiter.
    In Figure 3, element 100 is already fabricated. half of the surfaces 210 and 220, designated herein as the outer shell 110 molded into the surfaces 210 and 220 of the inner side of the side. In Figure 3, therefore, the outer shell 110 of the device remains in the first 210 and second surface 220 relative to the inner side of the side.
    Other parts of the device 200 also define a casting area on which the first part 112 of the outer shell, as well as other parts of the building element 100, can be cast. This casting area is further limited by a longitudinal mold 240 (Fig. 3) and two end molds 250 (see Fig. 7). In one embodiment, the longitudinal mold 240 is further arranged to support the first dielectric part 132 as described above. At least one of the end molds may support the core 130 at the end. However, if the support structure connecting the outer and inner shell is cast as described above, there is a space po between at least one end mold 250 and the core 130. a support structure.
    Referring to Fig. 5, in one embodiment, the casting area is further delimited by a longitudinal direction Sy continuous plate 245. The plate 245 is arranged to round the end of the casting area 200 of the device 200 where a plane parallel to said first surface 210 and a plane parallel to said second surface 220 The plate 245 can be used both when the angle between the surfaces 210, 220 is normal in the device, e.g. 90 degrees, or when the angle between the surfaces 210, 220 is adjustable to the desired angle ai. When the angle between the surfaces 210, 220 can be adjusted to a desired angle ai, the second surface 220 of the device may be provided at least in a first position and a second position where said first surface has normal Ns of said second face 220 in said first position. the normal Ns of the surface 220 points in one direction and an angle is between said first and second directions. Specifically, the plate 245 may be used in a solution with surfaces
    210, 220 the angle between normal can be adjusted to the desired angle ai
    20195038 prh 23 -01 to 2019 similar. In Figure 5, arrow 225 illustrates the rotation of the second surface 220 to the desired position. Turning can occur on the joint 215.
    The plate 245 is preferably flexible, whereby the same plate can be used to round said plurality of positions of different surfaces 220, 210 corresponding to a plurality of angles ai. The plate 245 may be secured to the first surface 210 and the second surface 220. The plate 245 may be detached and secured to the surface. to the surfaces 210, 220. The plate may be fixed or fastened to its fasteners. Po. the fasteners may be arranged to allow movement of portions of plate 245 in the direction of surface 210 and / or surface 220, for example toward and away from joint 215.
    Such movement of the plate 245 may promote suitable rounding of the outer corner at variable angles ai.
    Referring to Figures 5 and 6, in one embodiment of the invention, device 200 is arranged to be suitable for fabricating building elements 100 with at least two different angles ai as described above.
    The device 200 of Figs. 5 and 6 further comprises a hinge 215 for adjusting the angle between the first face 210 and the second face 220 of the device. In this embodiment, surfaces 210 and 220 are articulated to one another. The relative positions of the surfaces 210 and 220 are further lockable during casting. Thus, the angle α1 of the building element 100 is cast as desired, as described above. The inclination of the second surface 220 can be accomplished, for example, hydraulically or mechanically. The mechanical solution may comprise, for example, a suitable threaded rod and a corresponding nut. Further, the mold 221 may be provided only at predetermined suitable or conventional angles to the mold 211. Conventional angles can be, for example, 90 degrees, and at five, ten, or fifteen degrees at least in one direction. The hydraulic solution may comprise 30 hydraulic cylinders. The position can be locked, for example, hydraulically (e.g., by cutting off the hydraulic cylinder feed) or mechanically (e.g., by preventing the screw or the like from rotating, for example, by friction or a pin, or by locking the mold 221 to predetermined positions). The flexible plate 245 can also be used to round the angle in a device 35 in which the surfaces 210, 220 are not pivotally connected to each other so that the angle between them is constant, for example 90 degrees. If between surfaces
    20195038 prh 23 -01-20199 angle 210, 220 is standardized, instead of plate 245, a shaped mold can be used to round po. angle.
    As stated above, the casting area of the second inner member 124 is delimited by the second portion 134 of the core 130 5 and the first surface 264 of the inner mold 260 (see, e.g., Figure 3).
    Referring to Figure 6, the second surface 262 of the inner mold 260 may not be parallel to the first surface 210 of the device 200. This is particularly true when the device 200 comprises a hinge 215. As stated above, when the element 100 is manufactured, the first surface 264 of the inner mold 260 is substantially 10 parallel to the second surface 220 of the device 200. Thus, depending on the angle of the joint 215, the second surface 262 of the inner mold 260 may be disposed at an angle corresponding to the position of the joint 215 and the shape of the inner mold 260 with respect to the first surface 210 of the device. Referring to Figure 6, the inner mold 260 may be shaped such that even at a large angle α 1 (small angle β), the inner surface of the first portion 122 of the inner shell 120 remains planar.
    Referring to Figures 3 and 6, in some embodiments, the device 200 further comprises means 242 arranged during manufacturing 20 of the building element 100 to support the first outer portion of the core 130 of the building element 100.
    The surface of the plane 112 in the normal direction (such as the vertical) towards the plane of the first outer portion 112. Figures 3 and 6 show a depressor 242 arranged to support one insulating part 134 vertically downwardly from one end 134b of the second insulating part. In addition, or alternatively, if the angle cm was small (i.e., the angle between surfaces 210 and 220), it would be possible to support the second dielectric portion 134 into the inner mold 260 with support (not shown, but cf. support 140). the support would press one of the insulating members 134 towards the horizontal. In addition, or alternatively, it would be possible to support the first dielectric part 132 in the inner mold with support 260 (not shown, but cf. support 140), whereby the support would press down the first insulating member 132 downwards.
    For casting the inner shell 120 of the building element 100, in particular the second part 124 (such as the vertical part), the device 200 comprises means 255 (see Figures 3 and 7) for supporting the inner mold 260 in its first position Si.
    In Figures 3 and 7, the tool 255 is a projection or the like to which a web 256 (or a wire or rope or the like) can be attached. The inner mold 260 of Figures 3 and 7 comprises
    20195038 prh 23 -01-20199 corresponding means 265 to which a cloth 256 can be attached. In Figure 7, the length of the inner mold 260 in the direction Sy is slightly larger than the length L of the element, whereby the inner mold 260 stands over the horizontal portions of the end molds 250 as shown. By tightening the web 256, the inner mold 260 is supported in place, whereby the second part 124 of the inner shell can also be cast. The inner mold 260 comprises a first surface 264 defining an area for casting the second inner member 124. Preferably, the projection 255 is disposed in the device such that, when the inner mold 260 is in its first position Si, the device engaging means 255 is lower than the engaging means 265 of the engaging mold 260.
    221 the end closer to the surface 210 than the opposite end of the mold 221 thereon.
    In one embodiment of the invention, the inner mold 260 is a load-bearing structure 15, such as a metal beam or the like, which remains part of the finished building element 100. The device 200 does not comprise a reusable inner mold 260.
    Referring to Figures 4 and 6, in some embodiments of the invention, the device 200 comprises an inner mold 260. In this case, the inner mold 260 is operable to cast a plurality of building elements 100 successively over time.
    The inner mold 260 (reusable or part of the element) is arranged to be in the first position Si during manufacture of the building element 100. In Figures 3, 4, 6 and 7, the inner mold 260 is located at said first location Si (especially Fig. 4). At said first location, the inner mold 260 is arranged to define an area for casting a second part 124 of the inner shell 120 of the building element 100. In this case, the inner mold 260 is left with respect to 30 to the first 210 and second 220 inner side surface of the above-defined meaning. The inner mold 260 comprises a planar first surface 264 (Figure 3). At the first location, the first surface 264 of the inner mold 260 is substantially parallel to the second surface 220 of said device 200. Further, there is a distance between the first surface 264 35 of the inner mold and the second surface 220 of the device 200. As is apparent from the figures, this distance is arranged in the second portions 114, 134 and 14 of the building element 100
    20195038 prh 23 -01- 2019
    124 to CI12 + CI32 + CI22 (Figures 1 and 3). Further, there is a distance between the edge of the first surface 264 of the inner mold and the first surface 210 of the device 200 which is matched by the common thickness dn + d3i + d2i of the first portions 112, 132 and 122 of the building element 100 (Figures 1 and 3).
    If the device 200 comprises an (reusable) inner mold 260, the inner mold is further arranged to be in a second position S2 (Figure 4). The inner mold 260 is not shown in its second position in the figures. When the inner mold 260 is in its second position S2, the core 130 used to make the dielectric element 100 is at least partially positioned over the first surface 210 of the device. Preferably, the core 130 can then be placed in one piece at least partially over the first surface 210. Preferably, the core 130 can then be placed in one piece at least partially over the first surface 210 without rotating the core 130. "Untwisted" refers to a device in which core 130 has 15 adjustable po. in position such that the normal of the plane of the first dielectric portion 134 rotates po. up to 10 degrees during setting.
    For example, the second position S2 may be above the first surface 210, near the plane parallel to the second surface 220, and higher than the inner mold 20 260 in its first position S1 (Figure 4). For example, the second position S2 may be above a mold 221 having a second surface 220. Such a position has the advantage that when the device 200 is rotated to the removal position of the element 100 as described below, the second position S2 will be significantly lowered. At this location, the mold 260 is easily cleaned 25 for draining the next element 100. The device 200 may comprise means
    275 (Fig. 4) for receiving the inner mold 260 at its second position S2. The means 275 may comprise, for example, a fork or the like into which the inner mold may be inserted, for example, from its projections 265 (see Figure 4).
    Preferably, the first surface 210 of the device is metal so that the finished element 30 is easily removed from the device. The second surface 220 of the device is preferably made of metal, whereby the finished element is easily removed from the device. For example, boards such as plywood boards or the like may be used as end shapes 250. The end molds 250 may be provided with or comprise holes for mounting various fasteners to the building element 100 during casting. 35 For example, boards such as plywood boards or the like can also be used as the longitudinal mold 240. The longitudinal mold 240 may or may not be provided
    20195038 prh 23 -01-20199 comprises holes for mounting various fasteners to the building element 100 during casting.
    The end molds 250 may be integral parts of the device 200, or they may be manufactured individually according to the shape of the building element 100.
    Similarly, device 200 may comprise (a) a first end mold 250 or means for securing a first end mold 250 to the device 210 and (b) a second end mold 250 or means for securing a second end mold 250 to the device 210. Similarly, the device 200 10 may comprise an elongate mold 240 or a means for securing the elongated mold 240 to the surface 210. If the device 200 does not comprise a longitudinal mold 240, the aforesaid means for securing the longitudinal mold 240 may serve as a device 240 arranged to support the core 130 of the building element 100 in the direction of the plane of the first outer portion 112 of the building element 100. This support may be provided, for example, by a longitudinal mold 240 once it has been inserted. The means for securing the longitudinal mold 240 and / or the end mold 250 may comprise, for example, a magnet to enable the po. the molds may be attached to the first surface 210. Preferably, the mold 211 comprising the first 20 surface 210 comprises a material to which the magnet is magnetically attached.
    For example, the mold 211 may comprise a ferromagnetic material. The mold 211 may comprise, for example, iron, cobalt and / or nickel. The mold 211 may comprise a steel plate comprising a surface 210. The foregoing of the mold 211 and the first surface 210 also applies to the mold 221 and the second surface 220. The molds may not necessarily be attached to the second surface 220 but may be done e.g.
    Said end molds 250 are parallel to each other or comprise planar surfaces facing toward element 100 which are parallel. Said end molds 250 (or planes parallel thereto) form a first and second intersection lines with a plane parallel to a first surface 210. A plane parallel to said second surface 220 forms a third intersection with a plane parallel to the first surface 210. Said first and second cutting lines 35 are parallel. Said third cutting line is perpendicular to said first cutting line. Even more longitudinal
    20195038 prh 23 -01-20199 longitudinal direction of mold 240 is parallel to said third cutting line. In other words, the first outer portion 112 is planar and preferably rectangular in shape. Further, the second outer portion 114 is planar and preferably rectangular in shape.
    Referring to Figure 7, in one embodiment, each end mold 250 is plate-like and otherwise has a cross-sectional shape in a plane perpendicular to the longitudinal direction Sy of said element 100. In such an embodiment, the shape of the end mold 250 itself serves as a support for the inner mold 260. Thus, the inner mold 260 rests on the end molds 250 during the manufacture of the building element.
    In addition, the inner mold is supported by means 255, 256, 265 as described above in its first position Si.
    It is possible that the end molds 250 are larger in size and the end molds
    250 comprises supports to which inner mold 260 may be supported in said first position Si. The end molds 250 then comprise said means 255 for supporting the inner mold 260 in its first position Si.
    The device 200 according to one embodiment comprises an inner mold 260 and means for moving the inner mold 260 from a first position S1 to a second position S2 and (same or different) means for moving the inner mold 260 from a second position S2 to a first position S1. Preferably, the device 200 comprises means for moving the inner mold 260 from the first position S1 to the second position S2 and moving 25 from the second position S2 to the first position Si.
    Preferably, the inner mold 260 comprises a bracket for moving and securing the inner mold 260 to said second position S2. The inner mold 260 may comprise brackets 265 protruding at each end thereof (Figure 30 4). The same fasteners 265 may also be used to support the inner mold in its first position Si (see Figure 3).
    Referring to Figure 4, one embodiment of the device 200 comprises means 270 for leveling the upper surface of the molded first inner member 122. Such means 270 may comprise, for example, a trigger bar and / or a brushing bar. Here
    In an embodiment of 20195038 prh 23 -01-20199, the inner mold 260 preferably comprises a guide 268, such as a machine tool guide, to which the means 270 may be attached.
    Referring to Fig. 4, in one embodiment, the device 200 can be further provided in an outlet position. In said removal position, the building element 100 made in the device 200 is more easily removed from the device 200. The building element is more easily removed when the first outer portion 112 is pivotable to a vertical position, i.e., with a normal Nn the angle between normal Nn and horizontal is less than 30 degrees, such as less than 10 degrees. Similarly, in said outlet position, there is an angle between the normal 1 U plane and the horizontal plane parallel to surface 210 which is less than 30 degrees or less than 10 degrees (or else normal N4 is horizontal).
    In this embodiment, the device 200 comprises a body 300. The first surface 210 is pivotally attached to the body 300 by means of a joint 310. The device 200 further comprises an actuator 320, such as a hydraulic cylinder or screw, for tilting the first surface 210 to the release position. When the surfaces 210, 220 and the element 100 itself are inclined to said removal position, it is easier to lift the element 100 20 from the device 200 by means of a lifting device, for example using lifting loops 160 (Fig. 1).
    It is also possible to remove the element from the device when the surface 210 is substantially horizontal. If the element in this position were only lifted from said lifting loops 160, there would be a risk that the second outer portion 114 would break against the second surface 220. It may be possible to pull element 100 off surface 220 in horizontal direction, easier to access than horizontal drive devices. Therefore, the device 200 preferably comprises means 320, 310 for tilting the surface 210 to the removal position of the building element 100. In the removal position, the finished element 100 can be lifted from the device 200 without the risk of the second outer member 114 breaking against the surface 220 during lifting.
    The width of the first surface 210 of the device (the width W1 of Fig. 100, corresponding width of the element 100) is typically larger than that permitted by road traffic laws
    20195038 prh 23 -01 to 2019 for the maximum width of road transport. In this case, the device 200 may be more easily transported on the road in its ejection position than in its use position. The body 300 may be provided with wheels for moving or transporting the device 200.
    The dimensions of the device are preferably such that the aforementioned building element can be fabricated there. For example, the first surface 210 Sy of the first surface of the device (see Figure 1) may be 300 mm larger than the length L of the corresponding building element 100. What is said about the length of the first surface 210 also applies to the length of the second surface 220. Preferably, surfaces 210 and 220 are equally long in this direction. With the long device 200, it may be possible to fabricate two short elements simultaneously. For example, an additional end mold 250 may be disposed between said two end molds 250 to divide the casting region into two elements 100.
    As shown in Figures 3 and 1, the width 21 of the mold 211 comprising the first surface 210 is greater than the width W1 of the first outer portion 112. For example, the width of the mold 211 may be 500 mm greater than the width W1 of the first outer portion 112. The width of the mold 211 may be at least 3000 mm, at least 3500 mm, or at least 4000 mm.
    As shown in Figures 3 and 1, the width 22 of the mold 221 comprising the second surface 220 may be greater than the width 25 of the second outer portion 114 including the thickness of the first portion of the element, dn + W2. For example, the width of the mold 221 may be 100 mm greater than the width dn + W2 of the second outer portion 114 including the thickness of the first portion of the element. The width of the mold 221 may be at least 700 mm, such as at least 1000 mm.
