    PREFAB ARCH ELEMENT FOR ARCH Vaults This invention relates to a prefab arch element for erecting an arch vault and a method and a device for manufacturing such a prefab arch element.
    More specifically, the method and the device are particularly suitable for manufacturing prefabricated arch elements for erecting a trough vault.
    In addition, the present invention relates to a vault erected with such prefabricated arch elements and a method for erecting such a vault.
    Vaults are made of all kinds of materials.
    In order to erect masonry vaults, they are bricked on site, using a support construction (formal) to give the vault the desired shape. Masonry is applied to the support structure, following the shape of the support structure. Such masonry typically consists of stones (e.g. bricks) between which mortar is placed. However, it is also known, for example, to glue bricks to erect masonry. When the mortar or adhesive has dried, the support construction can be removed.
    The on-site bricklaying of vaults is a particularly time-consuming work that is often undesirable on contemporary construction sites. In addition, the vaults must be built in a position that is not very ergonomic and in an environment in which people are exposed to the weather.
    To be able to build vaults more smoothly, several prefab systems have already been devised, in which prefab concrete arch elements are used to erect a vault. Examples of this are described in EP 0947 639 A1 and MX 2013000403 A. However, such concrete arch elements do not provide the same aesthetic effect as masonry vaults.
    The object of this invention is to ensure that masonry vaults can be erected more easily.
    This object of the invention is primarily achieved by providing a prefabricated arch element for erecting an arch vault comprising two girder elements and arched masonry arranged between these girder elements.
    Such a prefabricated arch element can be manufactured in a workshop, where one can adopt a more ergonomic posture and where one is not subject to weather influences. In this way, such an arc element can be laid more easily than when it is being built on site.
    With the help of these prefabricated arch elements, it is much easier to build a vault on site on the construction site.
    In order to be able to place such arch elements smoothly: the girder elements are preferably arranged almost parallel to each other, the masonry being arranged completely between these girder elements.
    - the beam elements preferably form edges or even sides of the arc element. With the aid of such girder elements it is easier to realize a flat edge or even side to which other parts of a building can connect for installation or extension.
    - the beam elements preferably stand up on the convex side of the arcuate masonry with respect to this arcuate masonry. For instance, any additional elements of such an arc element can be arranged between these girder elements. It is also easier to connect external elements to these girder elements.
    The masonry of an arch element according to this invention preferably takes the form of a segment arch, where the arch segment occupies a maximum of a semicircle (to form a barrel vault) and preferably a segment arc smaller than a semicircle (to form a trough vault) ). This masonry can optionally also be designed as a pointed arch. The girder elements of an arc element according to this invention are preferably made of metal. These can be steel beams, for example. In addition to the girder elements and the arcuate masonry, a prefab arc element according to the present invention preferably also comprises concrete applied to the masonry, on the convex side of this masonry.
    This concrete is then preferably designed as reinforced concrete. For this purpose, for example, reinforcing steel is placed in the concrete.
    When the beam elements on the convex side of the arcuate masonry stand up relative to the arcuate masonry, this concrete is preferably arranged between these girder elements.
    Furthermore, an arch element according to the present invention preferably comprises transverse reinforcement elements disposed on the convex side of the masonry. Such transverse reinforcement elements serve to reinforce the masonry also in a direction transverse to the girder elements.
    These transverse reinforcement elements can be manufactured from metal, for example from steel.
    These transverse reinforcement elements preferably extend completely on this convex side.
    These transverse reinforcement elements can optionally be anchored in the masonry. In embodiments of arch elements which are provided with concrete as described above, these transverse reinforcement elements can alternatively or additionally be anchored in this concrete. In the case of reinforced concrete, the reinforcement can preferably be interwoven with these transverse reinforcement elements, for instance because reinforcement bars are arranged through openings in the transverse reinforcement elements.
    When the girder elements on the convex side of the arc-shaped masonry stand up relative to the arc-shaped masonry, these transverse reinforcement elements preferably extend between these girder elements and are even more preferably attached to these girder elements, for example by welding.
    Transverse reinforcement elements of an arc element according to this invention can take many forms. These can advantageously be manufactured from sheet metal, for example from sheet steel. These are then preferably arranged substantially parallel to each other between the girder elements.
    Each girder element of an arch element according to the present invention is in a particularly preferred embodiment designed as a profile with a substantially L-shaped cross-section, the short leg of this L-shape being arranged on the concave side of the arched masonry and the long legs of the L-shape of the two beam elements are arranged almost parallel to each other. In this way, the arch element can be supported on the short legs of the beam elements on a surface, whereby forces can be transferred in a uniform manner. With these short legs it is also easy to finish the edge of the prefabricated arch elements in an aesthetic way.
    With the long legs of the beam elements, the arch element can be made to connect and support against adjacent beam elements of adjacent arch elements or against an adjacent structure, whereby forces can also be transferred in a uniform manner. These long legs also make it possible to accurately place the arch elements in a simple way and to allow them to connect closely to adjacent elements.
    In order to simplify transport and handling of a prefab arc element according to the invention, this arc element is preferably provided with engaging elements for engaging it with a lifting device, such as for instance a hoisting crane.
    In the case of arch elements provided with concrete, these engagement elements can for instance be anchored in this concrete.
    In the case of arch elements comprising said transverse reinforcement elements, these engaging elements can for instance be incorporated in these transverse reinforcement elements. The object of this invention is additionally achieved by providing a vault with the above-described arch elements according to this invention. More specifically, such a vault can be, for example, a barrel vault or a trough vault.
    In a vault according to the present invention, the girder elements of adjacent arch elements are preferably arranged adjacent to each other. Per two adjacent girder elements of adjacent girder elements such a vault may more specifically comprise a finishing profile, which is arranged on the concave side of the arc elements over these adjacent girder elements. In order to be able to apply this finishing profile in a simple and aesthetic manner, it preferably has a substantially U-shaped cross-section.
    The object of this invention is further also achieved by providing a method for manufacturing a prefabricated arch element for erecting an arch vault, comprising the following steps: a. Providing a first beam element; b. laying a few layers of masonry on this first beam element; c. tilting the first beam element with the layers of masonry applied thereon; d. the laying of a few subsequent layers of masonry on top of the layers of masonry that have already been laid on the first beam element, e. repeating steps c and d to obtain a desired arcuate masonry 1s;
    f arranging a second beam element on top of the arcuate masonry that has been built on the first beam element. With such a method, the layers of masonry are each placed on top of each other in a substantially vertical manner and tilted until the desired arch shape is obtained. This makes it possible to build up the masonry much more smoothly than when layers of masonry are laid in a more horizontal manner.
    In step a, the first girder element can moreover be easily arranged on a surface that allows the layers of masonry to be laid on it in an ergonomic manner. Preferably, this is in an indoor environment that is not or only partially subject to weather influences.
    For step b, the bench can optionally be tilted in a desired slope to make it easier to apply the first layers of masonry.
    In steps b and d, the layers of masonry are laid in such a way that the desired arch shape is obtained. This can be easily realized by using the desired arc shape as a reference. This can be done, for example, by placing reference arcs with the desired arc shape on either side, stretching a cord between the two reference arcs and using this cord as a reference during bricklaying. These reference curves, which are set up on either side, must then be tilted in step c along with the first girder element and the layers of masonry applied to it.
    Step c must be carried out each time the slope of the top surface of the top layer of masonry applied on the first beam element becomes too steep to be able to lay a next layer of masonry on it. The first girder element and the layers of masonry applied thereon are then preferably tilted until this top surface has been brought almost horizontally or has been tilted just past it and assumes a slight slope.
    In steps b and f, the beam elements are attached to the masonry, for example with mortar or glue.
    More specifically, a method of this invention may include the following additional step: g. arranging support elements on the concave side of the arcuate masonry in steps b to d.
    With the aid of such support elements, a prefabricated arch element can be erected in a smooth manner, without having to allow mortar or glue to harden in the meantime during the laying of the masonry.
    Such support elements can be fitted where necessary or desired, in order to prevent the masonry from falling or deviating from the desired arch shape. This is certainly desirable if the masonry is not self-supporting when laying it until the mortar or glue between the bricks has hardened.
    Furthermore, a method of this invention may more specifically comprise the following additional steps: h. tilting the two beam elements with the arcuate masonry arranged between them, so that the convex side of the arcuate masonry faces upwards; ii arranging transverse reinforcement elements and / or reinforcement and / or concrete above the arcuate masonry and between the girder elements. In order to arrange transverse reinforcement elements between the beam elements, they can, for example, be welded to them and / or mounted with bolts, etc.
    When reinforcement is arranged between the beam elements, where transverse reinforcement elements are also arranged between them, this reinforcement is preferably interwoven with the transverse reinforcement elements, for example by providing reinforcing bars of this reinforcement through openings of the transverse reinforcement elements. In order to provide concrete between the girder elements, which are spaced apart with the arcuate masonry between them, formwork panels are preferably attached to the ends of these girder elements and the masonry, which are removed again after the concrete has hardened.
    A method according to this invention is particularly suitable for producing an arc element according to this invention described above.
    When the girder elements of such an arch element are designed as an L-shaped profile as described above, a first L-shaped profile is preferably applied with its long leg on a flat surface in step a, this with its short leg standing up with respect to the long leg. A first layer of masonry is then applied in step b on top of the long leg, against the short leg. Subsequent layers of masonry are then applied on top of them in steps b and d, with the short leg of the first beam element on the concave side of the arch being formed. After the masonry is completed, in step f the second beam member is placed on top of the last layer of masonry, with its long leg on top of this masonry and its short leg sideways next to this masonry, on its concave side.
    In addition, the object of the present invention is achieved by providing a method for erecting a vault with prefabricated arch elements, which comprises the following steps: a. Providing a plurality of prefabricated arch elements according to this invention described above;
    b. arranging these arc elements adjacent to each other, wherein beam elements of any two adjacent arc elements are disposed adjacent to each other.
    When the arc elements comprise said engaging elements, these arc elements can be lifted for this purpose by engaging them at these engaging elements with, for example, a hoisting crane.
    More specifically, to aesthetically finish a vault erected with a method of this invention, a method of this invention may comprise the following additional step: c. applying a finishing profile over these adjacent girder elements on the concave side of the arch elements per two adjacent girder elements of adjacent arc elements.
    With a method according to this invention, an above-described vault according to this invention is then preferably obtained.
    Finally, the object of this invention is also achieved by providing a device for manufacturing a prefabricated arch element for erecting an arch vault, which comprises the following elements: - a bench with a bearing surface for mounting a first beam element thereon; - tilting means for tilting the sofa through at least 90 °; - supporting means for supporting layers of masonry applied to the first girder element during bricklaying thereof; and holding means for holding against the bearing surface two girder elements with arcuate masonry arranged between them when tilting them.
    Such a device according to this invention can advantageously be used for manufacturing a prefabricated arch element according to a method according to the invention described above.
    The supporting surface of the bench of a device according to the present invention is preferably arranged at a height that allows the necessary layers of masonry to be applied to the first girder element arranged thereon in an ergonomic manner. Optionally, the bench can be set up so that it is adjustable in height, so that this height can also be adjusted during the laying of the masonry.
    Because the bench of a device according to the invention is designed to be tiltable, in a method according to the invention for manufacturing a prefabricated arch element in step c, the first girder element with the layers of masonry applied thereon can be tilted in a simple manner by tilting the bank on which this beam element is fitted. Because the bench can be tilted through 90 °, step h in the more specific embodiment of a method according to the present invention can be easily performed. With the aid of the holding means, the girder elements with the masonry arranged between them can simply be held against the bearing surface when they are tilted. The tilting means can be realized in many ways. These can, for example, be operated manually. Alternatively or additionally, these can also be motorized and / or hydraulic. More specifically, the support means may comprise support beams attachable to the bench on a first side of the support surface. Additional support elements can optionally be attached to these support beams. More specifically, the holding means may comprise holding bars attachable to the bench on a second side of the support surface, opposite the first side. Additional accessories can be attached to these retaining beams in order to hold the girder elements against the bearing surface with the masonry arranged between them. Such fittings are then preferably provided movably (slidably) on these holding beams.
    The masonry can herein be erected in a zone which, in the attached condition of these retaining beams and these supporting beams, extends between the retaining beams and the supporting beams. Said holding beams and / or said support beams are herein preferably detachably attachable to the bench. During the bricklaying in steps b and d in a method for manufacturing a prefabricated arch element according to this invention, the retaining beams are preferably not attached to the bench, in order to provide maximum access to the area in which the masonry is being erected to cover the layers of masonry. bricklaying. During step i of a more specific such method, the support beams are preferably not attached to the bench, in order to provide maximum access to this area to apply the transverse reinforcement elements and / or the reinforcement and / or the concrete. The retaining beams are then preferably attached to the bench, in order to support the whole of the girder elements with the masonry arranged in between. The device preferably includes legs to support the retaining beams at the end thereof disposed away from the bench. Said support beams and / or said holding beams can for instance be profiles. In a specific embodiment, a device according to this invention comprises two reference beams, which are attachable to the bench, and two reference arches, which are provided on the reference beams, for bricklaying the arched masonry between these reference arches with these reference arches as reference. As described above, a cord can then be stretched between these reference arches in order to follow the desired arch shape when laying the layers of masonry.
    This invention will now be further elucidated on the basis of the following detailed description of a prefab arch element, a method and an apparatus for manufacturing such a prefab arch element according to the present invention and a vault and a method for erecting such a vault according to the present invention. this invention.

The device shown in the figures comprises a bench (15), which here is mainly formed by an I-beam, with hollow tube profiles arranged transversely below it. Fixing holes (26) are provided at regular intervals in the L-beam. As can be seen in Figure 1, axle pieces (16) are attached to the bench (15), which are rotatably attached to support blocks (17).
    The bench (15) is rotatable by means of a belt transmission (20), reduction gear (19) and turntable (18) with lever. Reference beams (21) are attached to the bench (15), to which reference arches (22) are attached. Fixing elements (37) for fixing the reference beams (21) engage in some of the above fixing holes (26)
    from the bank (15). The reference beams (21) are spaced apart and parallel to each other. The reference beams (21) are arranged laterally of the bench (15), essentially upright with respect to a bearing surface (35) of this bench (15). The reference arches (22) extend above this bearing surface (35).
    A device according to the present invention may include a plurality of such reference arcs (22), which are interchangeably attachable to the reference bars (21).
    It is also possible to provide a device without such reference beams (21) and reference arches (22). Any profile can then be attached to the bench (15) as a reference beam. The reference arches (22) can then, for example, be sawn to size from a wooden plate and attached to the reference beams (21). It is also possible to manufacture a reference beam (21) and a respective reference arc (22) as one piece.
    On the bearing surface (35) of the bench (15), in a method according to this invention, using the device shown, an L-shaped profile (2) is applied in the area between the reference beams (21). This L-shaped profile is fitted with its long leg (14) on this bearing surface (35), with its short leg (13) standing up relative to this bearing surface (35). This profile (2) can, for example, be attached to the bench (15) with the aid of sergeants. The sergeant can be easily engaged on a flange of the I-beam.
    Layers of masonry are laid on this profile (2) by alternating layers of bricks (4) and layers of mortar (5) in a known manner, as can be seen in figure 2. During bricklaying, the arc shape of the reference arches (22) followed. For this purpose one can, for example, tension a rope between these reference arches (22).
    In order to brick the first layers of masonry, it is advantageous to first tilt the bench (15) forwards. In order to brick the next layers of masonry, it is advantageous to tilt the bench (15) a little more backwards each time. Preferably, several layers of masonry are always laid before the bench (15) can be tilted back.
    On the other side of the bench (15) than the side to which the reference beams (21) are attached, support beams (23) are attached to the bench (15).
    Threaded rods (27) are fixed for this purpose in said fixing holes (26) of the bench (15) and the support beams (23) are fixed with nuts (28).
    During bricklaying, the layers of masonry (4, 5) already applied are supported by arranging support elements (24) between the support beams (23) and the masonry (4, 5). For this purpose, these support elements (24) can be attached to the support beams (23) with the aid of sergeants (29).
    When the desired masonry (3) has been laid, as can be seen in figure 3, a second L-shaped profile (2) is placed on top of this masonry (3).
    Its long leg (14) is placed on top of the masonry (3).
    Its short leg (13) extends on the concave side of the masonry (3), as can be seen in figure 4. Preferably, the long legs (14) of both L-shaped profiles (2) extend parallel. to each other.
    Thereafter, on the same side of the bench (15) as the side to which the reference beams (21) are attached, holding beams (25) are attached to the bench (15) using threaded rods (27) that engage in said attachment holes (26) and nuts (28). Attachments (32) are slidably attached to these holding beams (25).
    The fittings (32) are provided with holding elements (26) which are pressed against the long leg (14) of the second L-shaped profile (2).
    The fittings (32) are secured to the holding beams (25) by inserting a pin through an underlying opening (30) in the corresponding holding beam (25) and by turning the threaded rod (32) against the holding beam (25). ). In this way, with the aid of these holding means (26, 31, 36), the whole of the L-shaped profiles (2) and the arcuate masonry (3) arranged between them can be held against the bearing surface (35) of the bench (15). turn into. The holding beams (25) are then attached to legs (33) at their end away from the bench (15). The bench (15) is then tilted 90 ° to the position shown in Figures 5 and 6, with the legs (33) resting on a surface. The support beams (23) and support elements (24) are released.
    Plate-shaped, U-shaped transverse reinforcement elements (7) are arranged at an intermediate distance from each other and substantially parallel to each other between the L-shaped profiles (2) on the convex side of the masonry (3). These transverse reinforcement elements (7) are welded to these profiles (2). Reinforcement (8) is also applied on the convex side of the masonry (3) between the L-shaped profiles. This reinforcement (8) is interwoven with the transverse reinforcement elements (7) by providing reinforcement bars thereof through openings (9) in these transverse reinforcement elements (7).
    Thereafter, the fittings (31) are shifted with respect to retaining beams (25), moving away from the second L-shaped profile (2).
    The transverse reinforcement elements (7) are provided with openings (10) which themselves can function as an engaging element, or in which brackets can be arranged as additional engaging elements, on which hooks (34) of a lifting device can be engaged. By grasping this with a lifting device, the whole of the L-shaped profiles (2) with masonry (3), transverse reinforcement elements (7) and reinforcement (8) placed between them can now be lifted off the holding beams (25). This whole is outlined separately in perspective in figure 7.
    Then shuttering panels are applied to the ends of the L-shaped profiles (2) and the masonry to pour concrete (6) on the convex side of the masonry (3) between the L-shaped profiles (2). Preferably, a concrete layer of about 5 cm is applied.
    After the concrete (6) has hardened, the shuttering panels can be removed again and a prefab arch element (1) as shown in figures 8 and 9 is thus obtained. With the aid of such arch elements (1), a vault (11) can be erected as shown in figure 11. To this end, the arch elements (1) are lifted and arranged adjacent to each other, with the long legs of L-shaped profiles (2) adjacent to each other. A U-shaped lacquered finishing profile (12) is then applied over the short legs of both L-shaped profiles (2) per two adjacent L-shaped profiles (2) of adjacent arch elements (1).
