Description
[0001] The invention relates to a wall bracket for a ventilated curtain wall and a ventilated curtain wall with multiple wall brackets.
[0002] In building construction, a ventilated curtain wall is a multi-layered external wall construction, which is specified in more detail, for example, in DIN 18516-1:2010-06.
[0003] Ventilated curtain wall systems comprise several wall brackets designed to be anchored in a load-bearing structure, particularly a load-bearing wall of a building. The load-bearing wall is typically an exterior wall of a building, to which the cladding elements of the ventilated curtain wall system can be attached directly or indirectly, for example via additional support profiles or other support elements such as brackets or similar components, using the wall brackets.
[0004] The cladding elements, typically arranged parallel to the load-bearing structure, especially the load-bearing wall, form the visible exterior surface of the facade and also serve as protection, particularly against driving rain. Wall brackets space the cladding elements laterally from the load-bearing structure. This creates a cavity between the cladding elements and the load-bearing structure, into which insulating material, such as rock or mineral wool, can be placed for thermal insulation. The insulating material is typically positioned directly adjacent to the load-bearing structure, especially the load-bearing wall.However, in a ventilated curtain wall, the space formed between the cladding elements and the supporting structure is usually not completely filled with insulation material; rather, a gap is typically formed directly behind the cladding elements, which serves in particular to drain away any moisture that has penetrated.
[0005] Since the cladding elements are attached to the supporting structure via wall brackets, these brackets represent a significant fire hazard. Wall brackets for ventilated curtain wall facades should therefore exhibit sufficient resistance to structural failure caused by heat in the event of a fire.
[0006] The wall brackets typically penetrate the thermal insulation layer of the facade and therefore generally represent thermal bridges that negatively affect the thermal insulation properties of the facade or its energy transmittance (also: U-value).
[0007] From WO 2016 / 165741 A1, a bracket for fastening facade elements, in particular of curtain wall facades, is known, comprising a wall fastening section designed for mounting the bracket on a building wall and a facade fastening section designed for mounting support or mounting profiles.
[0008] Further wall brackets are known from GB 2 503 970 A, KR 101 841 075 B1 and KR 2004 0018083 A.
[0009] Against this background, the present invention aims to provide an improved wall bracket for a ventilated curtain wall facade, which is particularly easy to manufacture and / or easy to provide for assembly and / or easy to handle and install and / or suitable for creating a ventilated curtain wall facade with good thermal insulation and / or improved fire protection. Furthermore, a ventilated curtain wall facade incorporating several such wall brackets is to be provided.
[0010] This problem is solved by a wall bracket having the features of claim 1 and a ventilated curtain wall having the features of claim 12. Advantageous embodiments and further developments are specified in the dependent claims.
[0011] The wall bracket (also: wall console) according to the invention for a ventilated curtain wall comprises a) a support element, b) a fastening device for fastening the support element to a load-bearing structure, in particular a load-bearing wall, c) a fastening blade designed for at least the indirect fastening of at least one cladding element of the ventilated curtain wall, wherein the fastening blade is a planar fastening blade whose planar extent is, for example, vertical, i.e., in the direction of gravity, or horizontal, i.e., perpendicular to the direction of gravity, or also inclined obliquely from the vertical, i.e., at any angle between 0 and 90° to the vertical, and d) a connecting element that is formed or attached to the fastening blade on the one hand and is attached to the support element on the other hand via a connection, e) wherein this connection between the connecting element and the support element is formed in a pre-assembly state of the wall bracket,in which the support part is not attached to the supporting structure by means of the fastening device, is designed to be captive, f) wherein the connection between the connecting part and the support part, in an assembly state of the wall bracket in which the support part is attached to the supporting structure by means of the fastening device, is designed to be load-bearing for the ventilated facade by means of the clamping force exerted by the fastening device between the support part and the supporting structure, g) wherein the support part comprises a support plate with a first side facing the supporting structure in the assembly state and a second side facing away from the supporting structure in the assembly state, h) wherein the connecting part is designed to be completely or partially planar, i) wherein at least a part of the planar extent of the connecting part lies in a plane perpendicular or inclined to the support plate,and j) wherein the connection between the connecting part and the support part comprises a continuous recess in the support plate, which is penetrated by the connecting part from the second side to the first side of the support plate, wherein an end section of the connecting part forms a rear grip over an edge of the recess on the first side of the support plate.
[0012] A fastening sword is understood to be a fastening element that is at least partially formed over a flat surface.
[0013] Known wall brackets are already inherently stable and thus load-bearing before being mounted to the supporting structure, thanks to their own welded, riveted, and / or screwed connections. The fastening device only needs to establish the load-bearing connection between the supporting structure and the wall bracket. A key advantage of the invention lies in the fact that, although the wall bracket is designed before installation in such a way that individual components cannot be lost—that is, with the exception of one fastening screw, the wall bracket is designed to be captive, or the components of the wall bracket are connected to each other in a way that prevents loss—the load-bearing, and in particular the force-fit, connection of all components is only created by the clamping force exerted by the fastening device, for example, a tightened fastening screw, between the support component and the supporting structure during installation.The fastening device thus performs two functions: the load-bearing, and in particular force-fit, stabilization of the wall bracket itself, and the load-bearing, and in particular force-fit, attachment of the wall bracket to the supporting structure. These two functions can be achieved in a single step by tightening the fastening device, for example, by tightening a fastening screw inserted through a fastening hole in the wall bracket. The resulting pressure of the wall bracket against the supporting structure accomplishes both functions simultaneously. Handling the wall bracket is therefore particularly simple, and the welding, riveting, and / or screw connections required by conventional wall brackets are eliminated.
[0014] The wall bracket according to the invention is easy to manufacture. In particular, due to the captive design of the connection between the connecting part and the support part in the pre-assembled state, it is easy to prepare for mounting on the supporting structure and is simple to handle. The assembly itself is also straightforward. The division of the wall bracket into a support part, mounting plate, connecting part, and fastening device ensures that the ventilated curtain wall can be designed with good thermal insulation. The load-bearing design of the connection between the connecting part and the support part in the assembled state, achieved through clamping forces, ensures sufficient resistance of the mounted wall bracket even under heat exposure, thus preventing heat-induced structural failure and providing the wall bracket according to the invention with good fire protection.
[0015] The ease of manufacture of the wall bracket also results from the fact that, in the wall bracket according to the invention, the fastening device not only performs the function of securely attaching the wall bracket to the load-bearing structure, but also the function already explained above of stabilizing the wall bracket itself. This eliminates the need for welding, riveting, and / or screw connections within the wall bracket, for example, between individual components of the wall bracket.
[0016] In particular, the elimination of welded joints for stabilizing the wall bracket offers the further advantage that different components or parts of the wall bracket can be made of different materials, especially different metals, for example, aluminum and stainless steel. The wall bracket according to the invention can therefore also be a hybrid wall bracket in which different components or parts consist of different materials, for example, aluminum and stainless steel. For example, a first component or part can be made of stainless steel and a second component or part of aluminum. Such a construction would not be possible if these components or parts had to be welded together. With the stabilization provided by the fastening device in the wall bracket according to the invention, such a construction can be easily achieved.For example, the support part of the wall bracket can be made of stainless steel, while the mounting plate, possibly including the connecting piece, is made of aluminum. A reverse design is also possible.
[0017] The wall bracket according to the invention can therefore be formed entirely without welding; in particular, it has no weld seams.
[0018] A captive connection between the connecting part and the support part in the pre-assembled state refers to a positive-locking connection in which the connecting part and the support part of the wall bracket cannot be separated from each other in the pre-assembled state, but may still be movable relative to each other. For example, the connecting part can be inserted through a recess in the support part and then fixed in such a way that, due to the positive lock between the connecting part and the support part, it is no longer possible to pull the connecting part out of the recess. For example, a projection on the connecting part, provided before insertion, can prevent this by fixing the connecting part in a predetermined position after it has been inserted through the recess. This can also be achieved, for example, by bending over the inserted end of the connecting part.
[0019] The load-bearing connection between the connecting part and the support part in the assembled state can be a force-fit connection. For example, this can be achieved by tightening the fastening device when attaching the support part to the supporting structure, thus transforming the initially positive-locking connection into a force-fit connection, for example by clamping an end of the connecting part, inserted through a recess in the support part, between the support part and the supporting structure.
[0020] The support plate provided according to the invention can be aligned parallel to the supporting structure. Typically, the supporting structure is aligned vertically, i.e., parallel to gravity. In this case, the support plate is preferably also aligned parallel to the supporting structure and thus also vertically.
[0021] The fastening blade can be designed as a flat surface, at least in sections, with the flat extent of the fastening blade lying in a plane perpendicular to the support plate, for example vertically, i.e. parallel to gravity, or horizontally or obliquely to the vertical.
[0022] Specifically, for example, when the wall bracket is mounted, the support part of the wall bracket can be attached to a vertical load-bearing structure, and the mounting plate can also be vertically oriented. In this case, the plane perpendicular to the mounting plate, in which the flat extension of the mounting blade lies, can be either a horizontal or a vertical plane.
[0023] The rear grip provided according to the invention can, for example, be a lateral projection extending beyond the narrow edge of the flat connecting part, and / or a bend, for example by 90°, of an end section of the flat connecting part at the end that is inserted through the recess. The recess and rear grip thus form the captive connection.
[0024] According to one embodiment, the rear grip forms a positive-locking connection between the connecting part and the support part in the pre-assembled state of the wall bracket.
[0025] According to one embodiment, in the mounted state of the wall bracket, the rear grip is clamped between the support plate and the supporting structure by the pressure force emanating from the fastening device, forming a load-bearing and / or force-locking connection between the connecting part and the support part.
[0026] According to one embodiment, the connecting part can be formed integrally with the fastening blade. However, it can also consist of several separate components that are mechanically and / or materially bonded together. In one embodiment, the connecting part and fastening blade can extend across a single surface.
[0027] According to one embodiment, the support part and the mounting plate are connected to each other via a further connection in addition to the connecting part. In particular, it can be provided that this further connection links the support part and the mounting plate directly or indirectly via one or more further connecting parts, either in one piece or in multiple parts.
[0028] The wall bracket can be made entirely of metal, particularly aluminum. Such metal constructions are also preferable from a fire safety perspective, as wall brackets made entirely of metal typically exhibit higher fire resistance than those made at least partially of plastic. This reduces the risk of complete structural failure of the wall brackets in the event of a fire and the associated risk of facade cladding elements becoming detached and falling.
[0029] However, as already explained, it is not mandatory for all components or parts of the wall bracket to be made of a single metal. A hybrid wall bracket is possible, meaning a design where different components or parts are made of different metals. For example, one or more primary parts or components could be made of stainless steel, and one or more secondary parts or components could be made of aluminum. For instance, the support bracket could be made of stainless steel, and the mounting plate, and possibly the connecting piece, of aluminum, and vice versa.
[0030] The fastening device can be a continuous recess or hole in the support member through which a fastener, such as a screw, is inserted and anchored in the supporting structure. The support member is held in place, for example, by the screw head, which does not fit through the recess or hole. This fastening screw could, for example, be a frame anchor screw.
[0031] The support component and / or the mounting bracket and / or the connecting part can each be manufactured in a particularly simple manner by cutting and / or punching and / or forming flat semi-finished products or sheet metal. The recess or hole for the mounting device can also be manufactured in this way. It is also possible for two or more of the aforementioned parts of the wall bracket to be formed and manufactured as a single piece. The entire wall bracket, with the exception of any fastener belonging to the mounting device, such as a screw, can also be formed and manufactured as a single piece. This simplifies the manufacturing of the wall bracket and / or reduces its production costs.The term "one-piece" refers in particular to components that consist of the same material and are manufactured, for example, from semi-finished products or sheet metal by means of cutting and / or punching and / or forming.
[0032] It is also possible that the support part and / or the mounting bracket and / or the connecting part are not manufactured and formed in one piece. If necessary, the connection between the parts can be made by a mechanical connection, for example, a connection made by rivets or screws, and / or a plug connection and / or a material-bonded connection, in particular by welding or laser welding.
[0033] Preferably, the wall bracket according to the invention has a shape that tapers in at least one dimension from the support part towards the fastening blade. This offers advantages when installing the ventilated curtain wall on a building, since typically the wall brackets are first attached to the supporting structure or wall, and then insulation materials are attached, particularly directly to the supporting structure or wall, such that at least the fastening blade protrudes from the insulation material. The insulation material, which is particularly in the form of mats, can be held at least temporarily by the wall brackets due to their widening structure towards the supporting structure or wall, thus simplifying installation.Furthermore, it can be assumed that the wall brackets' ability to secure insulation material, particularly with regard to vertical displacement, at least temporarily, is not completely lost even in the event of structural failure of the wall brackets during a fire. In other words, the wall brackets can prevent insulation material, especially fire-resistant insulation, from detaching prematurely or completely from the supporting structure during a fire.
[0034] In certain configurations, the wall bracket has a substantially T-shaped cross-section in cross-sectional planes parallel to the support element, the support plate, or the supporting structure, and / or in vertical cross-sectional planes. Insulation material, such as mineral wool or rock wool mats, can thus be easily slotted crosswise or T-shaped in the area of existing wall brackets and then positioned over the wall bracket already attached to the anchoring base. The structure of the wall bracket also allows such insulation mats to be held, at least temporarily, to the supporting structure or wall, which simplifies their final fastening during the installation of the ventilated curtain wall, for example, using screws, anchors, or other fasteners.
[0035] The wall bracket is specifically designed in such a way that it can be used in the manner described.
[0036] Terms such as "horizontal" and "vertical" are to be interpreted in the usual way within this description with reference to the Earth's gravitational field, especially when using the wall bracket described here as intended.
[0037] The invention further relates to a curtain wall with a plurality of wall brackets according to the invention attached to a supporting structure, in particular a load-bearing wall, wherein cladding elements of the curtain wall are attached at least indirectly to the fastening blades of the wall brackets.
[0038] Insulation material can be installed, for example, between the load-bearing structure or wall and the cladding elements that form the outer surface of the facade. At least the fastening lugs typically protrude from the insulation material, creating a gap between the insulation layer and the inside of the cladding elements. The cladding elements are typically attached to the fastening lugs using standard fasteners such as screws or brackets, or more complex support profile systems, all of which are commercially available in the construction industry.
[0039] The wall bracket according to the invention is explained in more detail below with regard to further features and advantages, based on the description of exemplary embodiments and with reference to the accompanying schematic drawing.

[0040] Corresponding parts are marked with the same reference symbols in all figures.
[0041] All five embodiments of the wall bracket 1 according to the invention comprise a support part 2, a fastening device 3 for attaching the support part 2 to a load-bearing structure, in particular a load-bearing wall, and a fastening bracket 4. The support part 2 each includes a support plate 7 with a first side 7a, which, in a mounted state of the wall bracket 1, faces the load-bearing structure (not shown), and a second side 7b, which, in a mounted state, faces away from the load-bearing structure. In the first, second, and third embodiments, the support plate 7 has lateral projections 8, which, in the mounted state, project towards the load-bearing structure and are pressed against the load-bearing structure (see FIG 1 , FIG 8 . FIG 13 ).
[0042] The fastening device 3 comprises a fastening opening 13 that extends through the support plate 7 and, if applicable, other components. The fastening device 3 also includes at least one fastening screw (not shown) for anchoring the wall bracket 1 in the supporting structure, which can be inserted through the fastening opening 13. When the wall bracket 1 is installed, this fastening screw is inserted through the fastening opening 13, and the screw head rests, possibly via one or more washers or similar components, against the second side 7b of the support plate 7, pressing the support plate 7 directly or indirectly, for example via the projections 8, against the supporting structure.
[0043] The fastening blade is flat in all embodiments (except for lateral projections in the first and second embodiments, see FIG 1 and FIG 8 , which are harmless for the designation "planar" within the meaning of this invention). In all five embodiments, the planar extent of the fastening blade 4 lies in a plane perpendicular to the support plate 7, the intended orientation of this plane in the first and second embodiments (see FIG 1 and FIG 8 ) in the intended assembly state horizontally and in the third, fourth and fifth embodiments (see FIG 13 , FIG 18 , FIG 23 ) is vertical in the intended installation position. The fastening blade has holes for the direct or indirect fastening of one or more cladding elements of the ventilated curtain wall facade.
[0044] Furthermore, all five embodiments feature a connecting part 5 which is formed on the fastening blade 4 (see FIG 1 , FIG 13 , FIG 18 , FIG 23 ) or appropriate (see FIG 8 ) is and, on the other hand, is attached to the support part 2 via a connection 6.
[0045] In the first embodiment ( FIG 1 bis FIG 7 The connection 6 comprises two recesses 9 in the carrier plate 7. One end of the connecting part 5 extends from the second side 7b of the carrier plate 7 through one of these recesses 9 to the first side 7a of the carrier plate 7 and is then bent over such that the connecting part 5 now runs parallel to the carrier plate 7 along its first side 7a, forming a reinforcement 8 for the fastening opening 13 passing through the carrier plate 7 and the connecting part 5 itself. This bent end section of the connecting part 5 forms a rear grip 10 over an edge of the first of the two recesses 9. Subsequently, directly at its end, the connecting part 5 is bent over again and inserted into the second of the recesses 9. Overall, this rear grip 10 forms a positive-locking connection between the connecting part 5 and the carrier plate 7, thus securing them together in a way that prevents loss.In the assembled state, the rear grip 10, in particular the section of the connecting part 5 running parallel to the side 7a of the carrier plate 7 between carrier plate 7 and supporting structure, is clamped and thus positively connected due to the pressing force emanating from the fastening device 3, specifically from the fastening screw and the fastening opening 13, so that the connection is stabilized and thus capable of supporting the ventilated facade.
[0046] In the second embodiment ( FIG 8 bis FIG 12 ) and in the third embodiment ( FIG 13 bis 17 The connection 6 includes a recess 9 in the carrier plate 7. One end of the connecting part 5 extends from the second side 7b of the carrier plate 7 through this recess 9 to the first side 7a of the carrier plate 7 and a reinforcement 14 located there, a plate with a continuous recess, and is then bent such that the connecting part 5 now runs parallel to the carrier plate 7 along its first side 7a (spaced apart by the reinforcement 14). This bent end section of the connecting part 5 forms a rear grip 10 over an edge of the recess 9 (spaced apart by the reinforcement 14) and thus a positive-locking connection between the connecting part 5 and the carrier plate 7, which are therefore securely fixed to one another.In the assembled state, the section of the connecting part 5 running parallel to side 7a of the carrier plate 7 between the carrier plate 7 and the supporting structure is clamped and thus positively connected due to the pressing force emanating from the fastening device 3, specifically from the fastening screw and the fastening opening 13, so that the connection is stabilized and thus capable of supporting the ventilated facade.
[0047] In the fourth embodiment ( FIG 18 bis FIG 22 ) and in the fifth embodiment ( FIG 23 bis 27 The connection 6 includes a recess 9 in the carrier plate 7. One end of the connecting part 5 extends from the second side 7b of the carrier plate 7 through this recess 9 to the first side 7a of the carrier plate 7. On the first side 7a of the carrier plate 7, the connecting part 5 forms a projection that creates a rear grip 10 over an edge of the recess 9. By appropriately tilting the end of the connecting part 5 with the projection, it can be inserted through the recess 9 and then brought into the intended final position, where the connecting part is otherwise secured. The rear grip 10 thus forms a positive-locking connection between the connecting part 5 and the carrier plate 7, which are therefore securely fixed together.In the assembled state, the projection and thus the rear grip 10 between the carrier plate 7 and the supporting structure is clamped and thus positively connected due to the pressure force emanating from the fastening device 3, specifically from the fastening screw and the fastening opening 13, so that the connection is stabilized and thus capable of supporting the ventilated facade.
[0048] In all five embodiments, the connection 6 between connecting part 5 and support part 2 is designed to be captive in a pre-assembled state of the wall bracket 1, in which the support part 2 is not attached to the supporting structure by means of the fastening device 3. Specifically, the captive connection 6 between connecting part 5 and support part 2 in the pre-assembled state is in each case a positive-locking connection.
[0049] Furthermore, in all five exemplary embodiments, the connection 6 between connecting part 5 and support part 2, in a mounting state of the wall bracket 1 in which the support part 2 is attached to the supporting structure by means of the fastening device 3, is designed to be load-bearing for the ventilated facade by means of the clamping force exerted by the fastening device 3 between the support part 2 and the supporting structure. Specifically, the load-bearing connection 6 between connecting part 5 and support part 2 is a force-fit connection in each mounting state.
[0050] In all five embodiments, the connecting part 5 is designed as a flat surface (except for lateral projections or inclined positions in the first embodiment, see FIG 1 , which are harmless for the designation "planar" within the meaning of this invention). In the first embodiment, part of the planar extent of the connecting part 5 extends in a plane inclined to the support plate 7; in the second, third, fourth and fifth embodiments, the planar extent of the connecting part 5 extends in a plane perpendicular to the support plate 7.
[0051] In the first, third, fourth, and fifth embodiments, the connecting part 5 is formed integrally with the fastening blade 4. In the second embodiment, however, the connecting part is a separate component that is connected to the fastening blade 4 at its end opposite the connection 6 to the support part 2. In the third, fourth, and fifth embodiments, the connecting part 5 and the fastening blade 4 extend together in a single surface or plane.
[0052] In all five embodiments, the support part 2 and the fastening blade 4 are connected to each other via a further connection 11 in addition to the connecting part 5, with one or more further connecting parts 12 being provided for this purpose.
[0053] In the first embodiment ( FIG 1 The two further connecting parts 12 are formed integrally with both the mounting bracket 4 and the support part 2. The connecting part 5 is also integrally connected to this, so that the entire wall bracket, except for the mounting screw (not shown), is formed in one piece.
[0054] In the second embodiment ( FIG 8 ) the two further connecting parts 12 are formed in one piece with both the fastening blade 4 and the support part 2, only the connecting part 5 and the reinforcement 14 and the fastening screw not shown form independent components.
[0055] In the third embodiment ( FIG 13 The further connecting part 12 is formed integrally with the support part 2. The fastening blade 4, which is formed integrally with the connecting part 5, constitutes an independent component, as does the fastening screw (not shown). The connection between the further connecting part 12 and the fastening blade 4 is achieved via a recess in the fastening blade 4, through which the further connecting part is inserted, and a bending of the further connecting part 12 around the edge of the fastening blade 4. One or both of these connection points may also be additionally secured by welding, although this is not strictly necessary.
[0056] In the fourth embodiment ( FIG 18 The further connecting part 12 is a separate component that is connected to both the mounting bracket 4 and the support part 2 by plug connections, whereby these connection points can also be additionally secured by welding, which is, however, not absolutely necessary. The fastening screw, not shown, also forms a separate component here.
[0057] In the fifth embodiment ( FIG 23 The further connecting part 12 is formed integrally with the support part 2. The fastening blade 4, which is formed integrally with the connecting part 5, constitutes a separate component, as does the fastening screw (not shown). The connection between the further connecting part 12 and the fastening blade 4 is achieved via a plug connection using recesses in both the fastening blade 4 and the further connecting part 12.
[0058] In all embodiments, the wall brackets 1 are made entirely of metal. This can be, for example, aluminum. The one-piece components can be manufactured, for example, from a sheet of metal by cutting and / or punching and / or forming. In the first embodiment ( FIG 1 The entire wall bracket, except for the fastening screw (not shown), is manufactured from a sheet of metal.
[0059] All wall brackets 1 described above are attached to the supporting structure or wall using one or more fastening screws. A flat insulating element can be placed between the wall bracket 1 and the supporting structure or wall for thermal insulation. Insulating material, particularly in the form of mats, can be easily fixed in the areas where the wall brackets 1 are already attached to the wall by slitting the mats according to the cross-sectional shape of the wall brackets 1 and then sliding them over the wall brackets 1. The fastening blades 4 of the wall brackets 1 protrude from the insulating material at their ends, creating a gap between the insulating material and the cladding elements, which are subsequently attached to the fastening blades 4, for example, by means of screws, brackets, or other fasteners.
