    Edge formwork.
    The present invention relates to an edge formwork.
    Edge forms, also called edge form plates, are well known.
    They are mainly used at the location of the side edges of the well-known precast concrete whey egg or wide-floor slabs.
    When these concrete slabs are placed on the load-bearing walls, a layer of concrete or so-called pressure layer is poured onto these slabs so as to provide a floor plate.
    The edge formwork is intended to prevent the poured concrete from flowing beyond the side edges of the concrete slabs placed, or in other words beyond the intended floor surface.
    The printing layer is, for example, a layer of 5 cm thick in which a reinforcement mesh is provided.
    Additional walls can be added to the poured concrete layer if necessary.
    The bearing walls on which the concrete cladding rests and also any walls that additionally form the floor slab usually form the inner leaf of a cavity wall.
    Against this, an insulation layer is usually provided, and further to the outside possibly an air cavity and the outer leaf of the cavity wall, or an occupation directly on the insulation layer.
    It is clear that the accurate execution of the insulation is of great importance.
    The known edge forms exist in different shapes and materials.
    The most rudimentary embodiment consists of wooden planks which are joined against the sides of the curvature requirement, for example nailed.
    It is clear that nailing is labor intensive.
    Another known embodiment of an edge formwork consists of a metal plate, preferably rectangular and pleated along a line parallel to the long sides, all such that an L-profile is obtained.
    This plate can consist of galvanized steel.
    A first member of the L-profile is placed horizontally under the crescents, i.e. is placed on the inner wall of the cavity wall, just before placing the vaulting.
    The second paragraph is oriented vertically and extends above the upper surface of the cladding and serves as actual edge formwork.
    A problem that arises is that the ends of these L-profiles, in particular the ends of the oriented members standing up in the installed state, tend to bend outwards under the pressure of the poured concrete.
    Deflection in general means that the surface of the outward facing side of the inner wall will be uneven after the poured concrete has hardened. Unevenness makes it difficult to subsequently apply the insulation layer against this side of the inner wall. This may result in a lack of space for this insulation, with the result that the concrete must be cut off.
    The deflection at the location of the ends and thus at the connection with a subsequent edge formwork profile is extremely undesirable since such deflection can provide a passage for the poured concrete to the cavity.
    It is known that concrete residues in the cavity are particularly disadvantageous for the quality of the insulation of a cavity wall, especially when this creates a connection or thermal bridge between the inner wall and the outer wall.
    Preventing deflection is therefore a major objective. It is clear that providing such edge formwork profiles with a greater thickness entails a possible solution, but at the expense of a greater material consumption and a higher cost price.
    In any case, the ends of such edge formwork profiles continue to offer less resistance to the pressure exerted by the concrete.
    Another known edge formwork differs from the L-shaped profile in that the upright member is provided with an edge directed transversely thereto, folded over and directed in the direction of the first member. An asymmetrical U-profile is thus obtained.
    This edge provides some additional resistance to deflection against the pressure of the poured concrete and offers some protection against injury during placement.
    However, such a profile offers no mutual connection at the location of the connection of different profiles.
    This profile has the disadvantage that it is not easy to stack. In addition, the profile has the disadvantage that the dumping height must correspond to the height of the profile since a dumping height which is lower than the profile height entails the disturbing presence of the bent edge during the further construction of the building construction. All this has as a consequence that customization is forced on what makes the profiles expensive.
    The present invention has for its object to provide a solution to one or more of the aforementioned and / or other disadvantages.
    To this end the invention relates to an edge formwork, which essentially consists of an L-section with first member and second member, whether or not manufactured from a plate, wherein at least one of the members is provided at or near at least one of the ends with coupling means .
    An advantage of providing coupling means consists in that the relevant edge formwork, in particular the member provided with coupling means, can be connected to an edge formwork of the same type or optionally of a different type, all such that the end in question has more resistance can withstand bending under pressure of the poured concrete.
    The intention is to use the member who is provided with the coupling means as a standing member who will serve as the actual formwork.
    By linking the profiles, the entire edge formwork can be anchored by means of a few steel nails by hitting the profile in the joint of the bottom wall.
    According to a preferred embodiment, the coupling means consist of two slots or incisions, which start at the free end of the respective member and extend up to a distance therefrom, all such that a bendable lip is obtained.
    By bending this lip slightly outside the plane of the relevant member, a V-shaped access is obtained in which the free end of the connecting edge formwork can be led.
    In this way a fixed and limited overlap distance is obtained and at the same time a greatly increased bending resistance.
    The bending resistance is otherwise increased if the coupling means can absorb the shearing forces partially or completely.
    With the insight to better demonstrate the characteristics of the invention, a few preferred embodiments of an edge formwork according to the invention are described below as an example without any limiting character, with reference to the accompanying drawings, in which: Figure 1 shows the connecting ends of two represents edge formworks according to the invention; figure 2 represents the connecting ends of the edge formworks according to figure 1, here in cooperating position; Figure 3 shows the placement of an edge formwork; Figure 4 shows the connecting ends of two alternative edge formworks according to the invention; figure 5 represents the connecting ends of the edge formworks according to figure 4, here in cooperating position.
    Figure 1 shows an edge formwork 1 according to the invention, in particular the first end 2 thereof, which according to the invention is provided with coupling means 3.
    As an extension thereof, on the right-hand side of the figures, the second end 4 of a second edge formwork 1 is shown, in this case, although not deducible from the figures and not necessarily, also of the type according to the invention.
    In Figure 2, these edge forms 1 are shown in cooperating position.
    The edge formwork 1 comprises a first member 5 and a second member 6 which is directed substantially transversely to the first member, here more particularly at an angle of 89 °.
    It is clear that this angle can be deviated from.
    The edge formwork 1 is here made of 1 mm thick galvanized sheet steel.
    The coupling means 3 here relate to a lip 7 formed by two slots or the like 8 which start at the free end 2 of the respective member 6 and which extend up to a distance thereof.
    A bendable lip 7 is obtained in this way.
    The lip 7 can and is here slightly bent outside the plane of the respective member 6 so that a narrowing access is obtained in which the free end 4 of the adjacent edge formwork 1 can be led.
    The use and operation of the edge formwork according to the invention is simple and as follows, with reference to Figure 3.
    The first paragraph 5 of the edge formwork 1 is placed horizontally under the arch requirement 9, i.e. is placed on the inner wall 10 of the cavity wall 11, just before placing the cladding 9.
    The second paragraph 6 is oriented vertically and extends above the upper limb 12 of the cladding 9 and serves as actual edge formwork for the poured concrete layer 13. As previously clarified, an insulating layer 14 is usually provided against the inner wall 10, and further to the outside, for example. a bricked outer wall 15.
    The connection of the edge formworks 1 according to the invention can be made, with reference to figures 1 and 2, by passing the free end 4 of an edge formwork 1 between the lip 7 and the surrounding parts of the free end 2 of the connecting edge formwork 1 .
    In this way a fixed and limited overlap is obtained and at the same time it is prevented that a passage can be obtained by mutually deviating deformation of the adjacent edge formworks 1.
    It is also possible that a greatly increased bending resistance is obtained at the free ends 2 and 4 of the adjacent edge formwork 1.
    The length of the slots 8 can for instance be 30 mm, so that the overlap of the formwork is also limited to this.
    The topmost slot 8 can for instance be provided 40 mm from the free edge of the second member 6, i.e. from the top edge in placed position.
    The thickness of the plate if the edge formwork 1 is made of sheet steel can be, for example, 1.5 mm, 1.25 mm or even 1 mm.
    The thinner the plate material, the easier the edge formwork profiles 1 can be cut and bent, such as might be desired at the location of a corner transition.
    Indeed, a simple cut in the first paragraph 5 could suffice to then bend the edge formwork profile 1. It is known that with thicker plates this bending is more difficult and does not produce the desired result.
    It is clear that the coupling means 7 prevent concrete or mortar from ending up in the cavity between the adjacent edge formworks 1, which makes it possible to use a thinner plate material.
    The coupling means 3 could alternatively, in contrast to the embodiment shown, be provided at both ends 2 and 4 with the edge formwork 1, for instance partly at the end 4 and partly at the end 2.
    Such an embodiment variant results in the advantage that it can additionally be provided for absorbing shaving forces between the upright second members 6, all such that mutual displacement is limited or even prevented.
    Indeed, if the free end of the lip 7 were to be provided with a bent edge which can cooperate with a groove or the like or a series of grooves provided at the free end 2 of the adjacent edge formwork 1, then both members 6 are prevented. parallel to the plane they form.
    Alternatively, an indentation or ridge or the like can of course be provided on the lip 7 and / or the other parts of the edge formwork 1 near the free end 2 and / or 4, which can or can co-act with a corresponding cavity, indentation or recess at the other end 4 and / or 2 of the adjacent edge formwork 1.
    However, the advantage of providing coupling means 3 at the location of only one of the ends 2 or 4 is that the edge formwork profiles 1 can then be sawn and / or cut to size at the site.
    The embodiment variant as shown in the figures can otherwise be designed such that, once the edge formwork profiles 1 have been combined, they require a considerable force to be separated from each other again. Dimensional tolerances and specific deformations at the location of the lip 7 and the surrounding parts can guarantee this.
    This degree of freedom can partly be maintained by repeatedly providing the coupling means 3 with the length profile of the edge formwork 1.
    Figure 4 schematically shows the connecting ends of two alternative edge forms 1 according to the invention.
    Both the first end 2 and the second end 4 of each edge formwork profile 1 are provided with complementary parts of the coupling means 3.
    In Figure 5 these edge forms 1 are shown in cooperating position.
    Here again, the edge formwork 1 comprises a first member 5 and a second member 6 which is directed substantially transversely to the first member, here more particularly at an angle of 89 °.
    It is clear that this angle can also be deviated from here.
    In the embodiment shown, the free edge of the second member 6, ie from the upper edge in the placed and shown position, is folded over so that a folded edge or so-called seamed edge 16 is provided which is partially omitted here at the second end 4 or taken away so that there is provided a single or thin upstanding edge portion 17.
    It is clear that, as an alternative to the omission of a part of the seamed edge 16, the latter can be compactly compressed locally, so that a thin upstanding edge portion 17 is provided.
    The flanged edge 16 here for instance has a height of 10 to 15 mm.
    The aforementioned single or thinly constructed upright edge portion 17 can be provided with the second free end 4 of the edge formwork profile 1 up to a distance of, for example, 30 mm from it.
    The edge formwork 1 is here manufactured from galvanized sheet steel of 0.7 mm thick.
    The use and operation of the edge formwork according to the invention as shown in Figures 4 and 5 is simple and largely consistent with the use and operation of the edge formwork according to Figures 1 and 2, with reference to Figure 3.
    The coupling means 3 are formed by, on the one hand, the seamed edge 16 at the location of the first end 2 of a first edge formwork 1 or edge formwork profile and, on the other hand, by the single or thinly erected raised edge portion 17 of a second edge formwork 1 or edge formwork profile.
    The connection of the edge formworks 1 according to Figs. 4 and 5 can be effected by inserting the single-edge or thinly constructed upright edge part 17 into the interior space of the adjoining flanged edge 16, whether or not clamping.
    In this way a fixed and limited overlap is obtained and at the same time a passage is prevented due to mutually deviating deformation of the adjacent edge formworks 1.
    A greatly increased bending resistance is thus provided at the free ends 2 and 4 of the adjacent edge formwork 1.
    The length of the single-edge or thin-edged upright edge portion 17 may, for example, be 30 mm, so that the overlap of the formwork is also limited to this.
    It is clear that the coupling means 3 prevent concrete or mortar from ending up in the cavity between the adjacent edge formworks 1, which makes it possible to use a thinner plate material.
    Passages or holes or the like may be provided in the upright second paragraph 6. These can be used to feed through wires or the like so as to connect the raised second paragraph 6 against bending, for example, to protruding steel wire parts as often provided on specific curves, in particular the so-called pre-dates.
    Such pre-dales are made thinner than the so-called usual dales and therefore require a higher poured concrete layer. Extra resistance to deflection often comes in handy.
    By providing the edge formwork with passages, the upright members 6 can additionally be held inwards by connecting them to the aforementioned steel wire reinforcements.
    It is clear that the seamed edge 16 can be bent both forwards and backwards, i.e. by folding the free upper edge in the direction of or away from the first paragraph 5.
    An important advantage of the embodiment as shown in figures 4 and 5 consists in that such edge formwork profiles 1 can be easily stacked and can be used at dumping heights that are lower than the height of the edge formwork profile 1.
    Indeed, the seamed edge is so thin that its presence, even when a dumping height is applied that is lower than the profile height, does not entail a disturbing effect during the further construction of the building construction.
    An elegant solution is thus provided which offers additional resistance to deflection and at the same time can be used flexibly. It is sufficient to use an edge formwork 1 according to the invention, the height of which is greater than the dumping height.
    In this way, edge formwork profiles 1 according to the invention can be offered in standard sizes, for example provided with a height of 200, 250 and 300 mm.
    For a dumping height of, for example, 230 mm, standard edge formwork profiles 1 with a height of 250 mm can be used. The upwardly projecting parts of the edge formwork profiles 1 do not form an obstacle during the further construction of the building construction.
    The present invention is by no means limited to the exemplary embodiments described and shown in the figures, but an edge formwork according to the invention can be designed in many shapes and dimensions without departing from the scope of the invention.
