Description

[0001] The invention relates to a support profile for a ventilated curtain wall, a support profile set with at least two such support profiles and a substructure for a ventilated curtain wall with one or more such support profiles and / or such a support profile set.

[0002] In building construction, a ventilated curtain wall is a multi-layered exterior wall construction, which is specified in more detail, for example, in DIN 18516-1:2010-06.

[0003] Ventilated curtain wall facades can be attached, for example, using anchor rods that are anchored to 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 cladding elements of an exterior facade can be attached using anchor rods and attached brackets, supported by profiles. Since the cladding elements are attached to a load-bearing structure via anchor rods, brackets, and profiles, stringent requirements are placed on the holding force, stability, and load-bearing capacity of these elements. In particular, anchor rods, brackets, and profiles must withstand both the weight of the facade and wind forces, i.e., forces parallel and perpendicular to the load-bearing structure.

[0004] The cladding elements, typically arranged parallel to the load-bearing wall, form the visible outer surface of the facade and also serve as protection, particularly against driving rain. Anchor rods space the cladding elements laterally from the wall. 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 inserted for thermal insulation.

[0005] In addition to anchor rods and brackets, such as wall brackets and / or fastening assemblies, support profiles are typically used to attach the cladding elements. These must also possess sufficient static stiffness, stability, load-bearing capacity, and strength.

[0006] Fig. Figure 1 shows the prior art known from DE 20 2025 104 324 U1. A perspective view shows a substructure 20 for a ventilated curtain wall facade with a fastening assembly 10 comprising an anchor rod 11, an anchor rod fastening unit 12, and a load transfer unit 15. The anchor rod 11 has a continuous external thread and is anchored on its wall side in a wall 18, in particular an exterior wall of a building. The anchor rod fastening unit 12 is provided on the side opposite the wall side of the anchor rod 11. This unit comprises locking components 13 and a facade mounting component 14, for example, designed as a fastening blade. A support profile 21 for a cladding element is attached to the facade mounting component 14.The anchor rod fastening unit 10 serves to absorb forces, in particular suction and pressure forces from wind, acting in a normal direction on the cladding elements of the facade. The load transfer unit 15 comprises a fixed-point nut 16 and a load transfer element 17. The load transfer element 17 serves to absorb forces acting parallel to the facade in the direction of gravity, in particular the weight of the cladding elements, including any existing supports.

[0007] The support profile 21 is usually oriented vertically, i.e., in the direction of gravity, and has a mounting flange 22 aligned parallel to the cladding elements to be attached, which forms a facade contact surface 25 for the cladding elements on its front 23. On its rear 24, a central web 26 projects vertically, on the first side 27 of which a mounting contact surface 29 is formed for attachment to the fastening assembly 10.

[0008] A disadvantage of this design of the support profiles is that horizontal forces parallel to the facade are absorbed exclusively by the cladding elements attached to the support profiles.

[0009] The invention is therefore based on the objective of providing a support profile that can absorb horizontal forces parallel to the facade. Furthermore, a support profile set comprising at least two such support profiles and a substructure comprising one or more such support profiles and / or such a support profile set are to be provided.

[0010] This problem is solved with respect to the support profile by a support profile having the features of claim 1, with respect to the support profile set by a support profile set having the features of claim 11, claim 13, or claim 14, and with respect to the substructure by a substructure having the features of claim 15. Advantageous embodiments and further developments are specified in the respective dependent claims.

[0011] The support profile according to the invention for a substructure for a ventilated curtain wall comprises a mounting flange with a front and a rear opposite the front, the front forming at least one facade contact surface for cladding elements of the ventilated curtain wall. The support profile further comprises a central web that projects vertically from the rear of the mounting flange and forms a mounting contact surface on a first side for attaching at least one component of a fastening assembly of the substructure. The central web can, for example, be arranged centrally on the mounting flange, so that the support profile is at least substantially a T-profile. However, the central web can also, for example, be arranged laterally offset or close to or at an edge of the mounting flange, so that the support profile is, for example, at least substantially an L-profile.The support profiles are usually elongated and extend with their longitudinal axis vertically, i.e. in the direction of gravity, parallel to the supporting wall or to the facade to be attached.

[0012] According to the invention, an undercut flange projecting from the central web is designed and arranged such that the undercut flange, together with the second side of the central web opposite the first side, forms an undercut for the positive-locking reception of an adapter part for, in particular, a rigid transverse connection with an adjacent support profile.

[0013] The advantages of the invention arise in particular from the undercut formed by the undercut flange on the second side of the central web. This undercut can positively engage one or more adapter parts, thereby forming a transverse connection, particularly a rigid one, to an adjacent support profile, thus increasing the stability and / or flexural stiffness of the substructure. This allows horizontal forces parallel to the facade to be absorbed, in addition to any attached facade cladding elements.

[0014] A further advantage arises from the fact that the undercut flange formed on the central web improves the stiffness, in particular the buckling stiffness of the support profile compared to known support profiles, and thus the support profile can absorb larger horizontal forces perpendicular to the facade, such as those that occur in wind suction, and is therefore more resilient compared to known support profiles.

[0015] According to one embodiment of the invention, the undercut flange on the second side of the central web can project obliquely towards the mounting flange, so that the central web and undercut flange have a V-shape in cross-section.

[0016] According to an alternative design variant, the undercut flange can project vertically from the second side of the central web and, at a distance from the central web, have a bend or kink towards the mounting flange. For example, the bend or kink can be 90°, so that the central web and undercut flange have a cross-section that is at least substantially rectangular in shape, open on one side.

[0017] A further development of the invention provides that the mounting flange has at least one recess extending from the facade mounting surface or one of the facade mounting surfaces, which is designed such that the screw head of a mounting screw passing through the recess does not protrude beyond the facade mounting surface. Using this mounting screw, for example, adapter parts and / or cross-connection profiles and / or brackets, for example for adapter parts and / or stiffening profiles, can be screwed to the mounting flange without the screw head protruding into the plane intended for the cladding elements and thus potentially hindering the installation of the cladding elements on the facade.

[0018] One embodiment of the invention provides that at least one guide groove, running parallel to the mounting flange, is formed in the first or second side of the central web for positioning the tip of a drilling tool for creating one or more through holes in the central web. This guide groove enables the easy creation of precisely positioned holes in the central web, which in turn allows for the precise insertion of cross-connection profiles between adjacent support profiles. Due to the guide groove, a precisely positioned hole can also be created on-site at a construction site if required, for example, to attach a cross-connection profile for additional stiffening.

[0019] One embodiment of the support profile according to the invention provides that one or more through holes are formed in the central web, optionally with the aid of one or more guide grooves, for inserting cross-connection profiles, in particular cross-sectionally round, square, or L-shaped cross-connection profiles. According to one embodiment, the offset and the hole can be positioned relative to each other such that a fastening screw extending through the offset secures the cross-connection profile inserted through the hole to the fastening flange. The cross-connection profiles arranged and fastened in this way enable the stiffening of the substructure between, in particular horizontally, adjacent support profiles and thus, for example, in addition to attached cladding elements and optionally in addition to adapter parts, allow for the absorption of horizontal forces parallel to the facade.

[0020] The drill holes can be positioned in the central web such that there is a gap of at least 10 mm between the edge of the drill hole and the free end of the central web on the side opposite the mounting flange. This is usually necessary due to the undercut flange. This gap also creates a distance between a cross-connection profile inserted into the drill hole and the underlying insulation, allowing for ventilation of the cross-connection profiles.

[0021] A further development of the invention provides that a thickening is formed at or near an end of the central web opposite the mounting flange, in which, in particular at one or both ends of the thickening, a bore for a fastening screw is provided, thereby allowing additional plates, for example firestop plates and / or cover plates, to be attached to the longitudinal ends of the support profile. Alternatively or additionally, a fixing groove running parallel to the mounting flange can be provided in the thickening on the first side of the central web.

[0022] One embodiment of the invention provides that an undercut web, in particular perpendicular to the central web, projects from the rear of the mounting flange. The central web and the undercut web are designed and arranged such that the first side of the central web and the undercut web form a further undercut for the positive-locking reception of an adapter part for a, in particular, rigid transverse connection with an adjacent support profile. In this way, undercuts for the positive-locking attachment of adapter parts are provided on both sides of the central web, i.e., on its first and second sides. This means that the support profile is connected on both sides to adjacent support profiles by means of the adapter parts, thereby stiffening the substructure on both sides of the support profile.

[0023] Additionally, a hole for a fastening screw can be provided at one or both ends of the thickening, allowing additional sheets, such as firestop sheets and / or cover sheets, to be attached to the longitudinal ends of the support profile.

[0024] The support profile set according to the invention comprises at least two support profiles according to the invention and at least one adapter part for a, in particular, rigid, transverse connection between two adjacent support profiles. The adapter part(s) have one or more projections that interact positively with the undercut(s) and / or further undercuts.

[0025] According to a further development of the support profile set, two interconnected adapter parts form the cross connection between two adjacent support profiles, whereby the two adapter parts can be moved relative to each other to adapt to the distance of the adjacent support profiles before the connection is fixed.

[0026] The form-fitting arrangement of the adapter parts between adjacent support profiles stiffens the substructure between, in particular horizontally, adjacent support profiles and thus, for example, in addition to attached cladding elements and, if necessary, in addition to cross-connection profiles, absorbs horizontal forces parallel to the facade.

[0027] The support profile set according to the invention can alternatively or additionally be designed as follows: The support profile set comprises at least two support profiles according to the invention and at least one cross-connection profile. In the central web of the support profiles, one or more through holes are formed for inserting cross-connection profiles, in particular cross-sectionally round, square or L-shaped cross-connection profiles, wherein the inserted cross-connection profile(s) are screwed to the support profiles and form a, in particular rigid, cross-connection between adjacent support profiles.

[0028] The support profile set according to the invention can alternatively or additionally be designed as follows: The support profile set comprises at least two support profiles according to the invention. Furthermore, the support profile set comprises at least one corner profile, which has at least two mutually perpendicular facade contact surfaces for cladding elements of the ventilated curtain wall. The corner profile is connected to adjacent support profiles, in particular in a rigid manner, via cross-connection profiles. A separate connection of the corner profile to the load-bearing wall, for example via an anchor rod, is not required and / or provided. The forces acting on the corner profile are thus absorbed via the cross-connection profiles. The cross-connection profiles ensure the required stability and / or load-bearing capacity of the corner profile.Since no direct attachment of the corner profile to the load-bearing wall, for example via an anchor rod, is provided, it is at least a largely thermal bridge-free corner solution for the substructure.

[0029] This corner solution also has the advantage that the corner profile is easier to measure and / or adjust compared to a directly attached corner profile. Furthermore, this corner solution allows for perfectly aligned installation of the corner profile, as the alignment is virtually self-aligning thanks to the precise geometry of the support profiles and, in particular, the precisely drilled holes for the cross-connection profiles, which are created by guide grooves.

[0030] The substructure according to the invention for a ventilated curtain wall comprises one or more support profiles according to the invention and / or a set of support profiles according to the invention. The advantages of this substructure will become apparent from the preceding explanations of the support profile and the set of support profiles according to the invention.

[0032] Corresponding parts and components are designated with the same reference numerals in the figures, even across different embodiments. The figures are not necessarily drawn to scale, and scales may vary between figures.

[0033] Fig. Figure 1 shows a perspective view of a substructure 20 for a ventilated curtain wall with a support profile 21 according to the state of the art. Fig. Point 1 was already explained at the beginning of the description.

[0034] Fig. 2 to Fig. 5 as well Fig. 12 to Fig. Figure 17 shows various embodiments of support profiles 21 according to the invention for a substructure 20 for a ventilated curtain wall. The support profiles 21 have in common that they have a mounting flange 22 with a front face 23 and a rear face 24 opposite the front face 23, wherein the front face 23 forms a facade contact surface 25 ( Fig. 2 to Fig. 5 as well Fig. 14 and Fig. 15 and Fig. 16 and Fig. 17) or two facade installation areas ( Fig. 12 and Fig. 13) for cladding elements of the ventilated curtain wall. Furthermore, the support profiles 21 have a central web 26 which projects vertically from the rear 24 of the fastening flange 22 and forms a mounting contact surface 29 on a first side 27 for fastening at least one component of a fastening assembly 10 of the substructure 20. The support profiles 21 also have in common that an undercut flange 30 projecting from the central web 26 is designed and arranged such that the undercut flange 30, together with the second side 27 of the central web 26 opposite the first side 27, forms an undercut 31 for the positive-locking reception of an adapter part 32 for a, in particular, rigid transverse connection with an adjacent support profile 21. The design of such a transverse connection is described below with reference to Fig. 10 and Fig. 11 explained in more detail.

[0035] In the exemplary embodiment of the support profile 21 according to Fig. 2 and Fig. 3 The undercut flange 30 protrudes obliquely towards the mounting flange 22 on the second side 28 of the central web 26, so that the central web 26 and the undercut flange 30 have a V-shape in cross-section.

[0036] In the exemplary embodiment of the support profile 21 according to Fig. 4 and Fig. 5 The undercut flange 30 projects perpendicularly from the second side 28 of the central web 26 and has a bend or kink in the direction of the fastening flange 22, spaced apart from the central web 26. The bend or kink is 90°, so that the central web 26 and the undercut flange 30 have a cross-section that is at least substantially open on one side of a rectangle.

[0037] In the exemplary embodiments of the support profile 21 according to Fig. 12 to Fig. 15 a thickening 42 is formed at an end of the central web 26 opposite the mounting flange 22, in which a fixing groove 43 running parallel to the mounting flange 22 is provided on the first side 27 of the central web 26.

[0038] In the exemplary embodiments of the support profile 21 according to Fig. 16 and Fig. 17 a thickening 42 is formed near an end of the central web 26 opposite the mounting flange 22, namely in a transition section to the undercut flange 30.

[0039] In the exemplary embodiments of the support profile 21 according to Fig. 12 to Fig. 17 A bore 44 for a fastening screw is provided at the upper end of the thickening 42, which allows an additional sheet, for example a fire-resistant sheet and / or cover sheet, to be attached to the longitudinal end of the support profile 21.

[0040] Furthermore, in the exemplary embodiments of the support profile 21, it is stated that Fig. 12 to Fig. 17 on the rear side 24 of the mounting flange 22, an undercut web 45 extends perpendicularly to the central web 26. The central web 26 and the undercut web 45 are designed and arranged such that the first side 27 of the central web 26, in Fig. 12 to Fig. 15 together with the fixing groove 43, and the undercut web 45 form a further undercut 46 for the positive-locking reception of an adapter part 32 for a, in particular, rigid, transverse connection with an adjacent support profile 21. In this way, undercuts 31 and 46 for the positive-locking attachment of adapter parts 32 are provided on both sides of the central web 26, i.e., on its first side 27 and second side 28. This means that the support profile is connected on both sides to adjacent support profiles by means of the adapter parts 32, and the substructure is thereby stiffened on both sides of the support profile 21.

[0041] All illustrated embodiments of the support profile 21 according to the invention have in common that the fastening flange 22, extending from the facade mounting surface 25 or one of the facade mounting surfaces 25, has at least one recess 33, which is designed such that the screw head of a fastening screw passing through the recess 33 does not protrude beyond the facade mounting surface 25. Depending on the embodiment, the fastening flange 22 terminates in the recess 33 ( Fig. 4 and Fig. 5 as well Fig. 12 to Fig. 17) or the fastening flange 22 is transferred to the plane of the facade mounting surface 25 on both sides of the setback 33, i.e. the setback 33 is a trough ( Fig. 2 and Fig. 3).

[0042] In all embodiments of the support profile 21 according to the invention, at least one guide groove 34 running parallel to the mounting flange 22 can be formed in the first side 27 or in the second side 28 of the central web 26 for positioning a tip of a drilling tool for producing one or more through holes 35 in the central web 26. For example, in Fig. 4 and Fig. 5 and also in Fig. 6 Two parallel guide grooves 34 are shown on the first side 27 of the central web 26.

[0043] Fig. 6 illustrates this using the exemplary embodiment of the support profile 21 according to Fig. 4 and Fig. 5. The formation and use of a borehole 35 in the central web 26. The borehole is formed by positioning the tip of a drilling tool in one of the guide grooves 34. A cross-connection profile 36 is inserted through the borehole 35.

[0044] The specific fastening and use of the cross-connection profiles 36 is described in the following. Fig. 7 and Fig. This is illustrated by the eight support profile sets shown. Three different cross-sectional profiles 36 are shown symbolically to demonstrate that they can, for example, have a round, square, or L-shaped cross-section. The cross-sectional profiles 36 are each inserted through boreholes 35 in the central webs 26 of two horizontally adjacent support profiles 21, thus connecting them. Fastening screws 37, for example, self-tapping screws, are provided for fastening the cross-connecting profiles 36 to both support profiles 21. These screws extend through the recess 33 in the fastening flange 22 and screw into the respective cross-connecting profile 36. To simplify the positioning of these fastening screws, a guide groove 38 can be provided in each recess 33.The offset 33 and the borehole 35 are positioned relative to each other such that a fastening screw 37 extending through the offset 33 secures the cross-bracing profile 36, inserted through the borehole 35, to the fastening flange 22. Due to the offset 33, the screw head of the fastening screw 37 does not protrude beyond the facade contact surface 25 and therefore does not impede the installation of the facade cladding elements. The cross-bracing profiles 36, arranged and fastened in this manner, stiffen the substructure 20 between horizontally adjacent support profiles 21 and thus, for example, in addition to installed cladding elements and, if necessary, in addition to adapter parts 32, absorb horizontal forces parallel to the facade.

[0045] In Fig. 7 and Fig. Figure 8 shows that the central web 26 in the lower section of the support profiles 21 has been almost completely removed. This may be necessary on-site at the construction site to create space in narrow areas of the building, such as around roller shutter boxes. The offset 33 ensures that sufficient residual stiffness of the support profile 21 is maintained in this area as well. Furthermore, in Fig. 7 and Fig. Figure 8 shows that in the area of ​​this removed central web 26, a stiffening profile 49 is attached to one of the support profiles 21 by means of fastening screws, the fastening screws being countersunk in the recess 33 so that their screw heads do not protrude beyond the facade contact surface 25. This increases the stiffness in this area.

[0046] Fig. Figure 9 shows a corner solution. The illustrated support profile set comprises four support profiles 21 according to the invention and a corner profile 47, which has two facade mounting surfaces 48 oriented perpendicular to each other for cladding elements of the ventilated curtain wall. The corner profile 47 is connected to adjacent support profiles 21, in particular in a rigid manner, via cross-connection profiles 36. The cross-connection profiles 36 ensure the required stability and / or load-bearing capacity of the corner profile 47. A separate, direct fastening of the corner profile to the load-bearing wall, for example via an anchor rod, is therefore not provided, so that the corner solution is designed to be largely free of thermal bridges.

[0047] Fig. 10 and Fig.Figure 11 shows a support profile set with two support profiles 21 and two adapter parts 32 for forming a, in particular, rigid transverse connection between the two horizontally adjacent support profiles 21. The adapter parts 32 each have two projections 39 which interact positively with the undercut 31. To engage the transverse connection at the distance between the two support profiles, the two adapter parts 32 form the transverse connection by overlapping and being slidable relative to each other.

[0048] After insertion into the undercuts, the position of the two adapter parts relative to each other is fixed by fastening screws. For this purpose, at least one of the adapter parts 32 has bores 40 for the fastening screws (not shown). To hold the adapter parts 32 in the intended position on the support profiles 21 after insertion into the undercuts 31, brackets 41 for the adapter parts 32 are attached to the support profiles 21. These brackets can, for example, be fastened at the desired position on the respective support profile 21 by means of fastening screws inserted through the respective offset 33.
