Description

[0001] The invention relates to a curtain wall facade with the features of the preamble of claim 1.

[0002] Patent EP 3 329 066 B1 discloses an impact wall construction for a gymnasium with wall panels that are suspended from a wall in the gymnasium by hooks on their backs. The wall panels are connected to each other by tongue and groove joints.

[0003] Utility model CN ​​218 714 580 U discloses a wall cladding for sports facilities with wall panels that are screwed to the inside of a wall of the sports facility. The wall panels have complementary, interlocking profiles at their top and bottom edges. A profile strip is placed on the profile at the top edge of the wall panels. Screws for fastening the wall panels to the wall are inserted through this profile strip, which engages in a groove in the profile at the bottom edge of the wall panels. The profile at the bottom edge of the wall panels covers the screw heads and the profile strip on the outer surface of the wall panels facing away from the wall.

[0004] The object of the invention is to propose a curtain wall that allows for easy adjustment of the distance from a building wall.

[0005] This problem is solved according to the invention by the features of claim 1. The curtain wall according to the invention has a facade cladding with at least two and preferably more panels, which are arranged one above the other on and at a distance from the building wall – preferably in a plane parallel to a building wall. A "panel" is understood to be a board, a plank, or generally a cladding element, which can be made of any material.In the following, a panel arranged below another panel will be referred to as a "lower panel" and a panel arranged above another will be referred to as an "upper panel", wherein the facade has several lower and several upper panels if it has more than two panels arranged one above the other, wherein, apart from a bottommost and a topmost panel, each panel is both a lower panel, namely arranged below another / upper panel, and an upper panel, namely arranged above another / lower panel.

[0006] According to the invention, the upper panel(s) have a lower groove in a lower edge, and the lower panel(s) have a tongue on an upper edge that engages in the lower groove in the lower edge of the upper panel in the manner of a tongue-and-groove connection. The tongue is, in particular, a strip-shaped connecting element that extends along the upper and lower edges of the stacked panels. However, in embodiments of the invention, the tongue can also be short and then more accurately described as a disc rather than a strip. The tongue can be a separate component or an integral part of the lower panel(s).

[0007] According to the invention, a bottom panel, that is, a lower panel of the facade cladding below which no other panel is arranged, is arranged on a bracket that is mounted on the building wall. The bracket is an element that supports the bottom panel, and the other panels can be supported on the bottom panel in such a way that the bracket supports the entire facade cladding.

[0008] Furthermore, the facade according to the invention features a spacer for the facade cladding, which connects the tongue and, via the tongue, the panels to the building wall in a tensile-resistant manner, such that the distance between the facade cladding and the building wall cannot be increased. According to the invention, the upper panel(s) overlap the spacer on their lower edges on an outer surface facing away from the building wall, such that the tongue is held at its distance from the building wall. Because the tongue connects the superimposed panels of the facade cladding in a tongue-and-groove manner, the tongue holds the panels, or rather the facade cladding, at their distance from the building wall.

[0009] The dependent claims relate to advantageous embodiments and further developments of the invention specified in claim 1.

[0010] One embodiment of the invention provides that the spring is a separate component that connects the lower panel at its upper edge and the upper panel at its lower edge. For this purpose, the upper edge of the lower panel has an upper groove and the lower edge of the upper panel has a lower groove, and the spring engages in the two grooves in the manner of a tongue-and-groove connection, thus connecting the two panels.

[0011] One embodiment of the invention provides that the spacer has a fastener that is anchored in the building wall and that passes through the spring of the facade cladding, thereby creating a tensile-resistant connection to the building wall. The invention does not preclude an additional compression-resistant connection of the spring to the building wall, but it also does not require such a connection. The spacer can, for example, have a threaded rod as a fastener, which is anchored in an anchor hole in the building wall, for example, by means of mortar, adhesive, synthetic resin, or the like, or with an expansion anchor. Another embodiment of the invention provides a long-shaft anchor as the fastener for the spacer, which is anchored, for example, in the anchor hole in the building wall and whose hollow shaft, in particular a tubular shape, passes through the spring of the facade cladding.For example, a so-called frame anchor can also be used as a long-shaft anchor or as a fastener for the spacer. Preferably, the upper panels overlap one end of the frame anchor or long-shaft anchor at their lower edges. This creates a compression-resistant connection. A long-shaft anchor, in this context, refers to an anchor that is embedded in the building wall and whose shaft bridges the gap between the building wall and the facade cladding, extending through the tongue and groove of the facade cladding, regardless of the anchor's actual length. The compression-resistant connection arises because the overlap of the long-shaft anchor's end by the lower edge of the upper panel compensates for the compressive force exerted by the panel towards the building wall.The overlap of the long-shaft anchor end can also be seen as the end of the long-shaft anchor overlapping the lower edge of the upper panel. More precisely, an expansion element, such as an expansion screw, which is inserted into the hollow shaft of the long-shaft anchor to expand it in the building wall, compensates for the compressive force. The lower edge of the upper panel can then rest directly against the head of the expansion element. Thus, the panels cannot be pushed towards the building wall when the long-shaft anchor is properly expanded in the building wall by the expansion screw.

[0012] In particular, in embodiments of the invention, the lowest panel of the facade cladding rests on the console arranged on the building wall, and the upper panel(s) rest on a lower panel arranged below them, such that the facade cladding as a whole rests on the console.

[0013] The bracket preferably has a height adjustment mechanism, allowing the height of the lowest panel and thus the overall height of the facade cladding to be adjusted, and / or a distance adjustment mechanism, allowing the distance of the lowest panel, which rests on the bracket, from the building wall to be adjusted. By adjusting the height of several brackets arranged side-by-side at a distance from one another on the building wall, the lowest panel, and thus the entire facade cladding, can be aligned horizontally.

[0014] One embodiment of the invention provides that the spacer has a mounting bracket, the first leg of which is attached to the building wall. A second leg of the mounting bracket projects from the building wall. The spring of the facade cladding is arranged on the second leg of the mounting bracket that projects from the building wall. It projects, in particular, upwards into the lower groove in the lower edge of an upper panel and, in embodiments of the invention, also downwards into the upper groove in the upper edge of a lower panel.

[0015] To form the grooves, one design provides a profile on the back side of a panel of the facade cladding facing the building wall, which together with the panel forms the upper groove or the lower groove of the panel.

[0016] One embodiment of the invention provides that the panels or the facade cladding have a thermal insulation layer. For example, the panels are sandwich panels or sandwich panels that have a thermal insulation layer and a facing layer made of, for example, a metal sheet or a metal foil, or of plastic or wood on one or both sides.

[0017] One method involves adjusting the spacing of the facade cladding of the curtain wall before an upper panel is placed on a lower panel. To do this, the spacer is inserted through the tongue of the facade cladding into an anchor hole in the building wall. The distance of the tongue from the building wall is then adjusted by axially sliding the spacer with the tongue, or by sliding the spacer with the tongue perpendicular to the building wall. The spacer is then anchored in the anchor hole in the building wall, and the upper panel is placed onto the tongue with its lower groove along its bottom edge. The upper panel overlaps the fastener on the outer side facing away from the building wall, thus maintaining its distance from the wall. If the spacer has a long-shaft anchor, this is inserted through the tongue and into the anchor hole in the building wall.To adjust the spacing, the long-shaft anchor is moved axially and then expanded in the anchor hole to secure it in the building wall. The lower panel, or a lower panel, is preferably positioned in front of the fastener on the building wall. It has an upper groove in its upper edge into which the spring is inserted, or the lower panel incorporates the spring as an integral part.

[0018] The features and combinations of features, embodiments, and configurations of the invention mentioned above in the description, as well as the features and combinations of features mentioned below in the figure description and / or drawn in a figure, are not only usable in the combinations specified or drawn, but also in any other combination or individually. Embodiments of the invention are possible that do not have all the features of a dependent claim. Individual features of a claim can also be replaced by other disclosed features or combinations of features. Embodiments of the invention are possible that do not have all the features of the exemplary embodiment(s), but rather any part of the characterized features of an exemplary embodiment, possibly in combination with one, several, or all features of one or more further exemplary embodiments.

[0019] The invention is explained in more detail below with reference to several exemplary embodiments illustrated in the drawings. The drawings show: Figure 1 shows a vertical section of a curtain wall according to the invention; Figure 2 shows a detail of an alternative embodiment of the invention; and Figures 3 to 5 show further embodiments of the invention.

[0020] Basically, identical parts in the figures are assigned the same reference numbers.

[0021] The Figure 1 The illustrated curtain wall 1 according to the invention comprises a building wall 2 and a facade cladding 3, which is arranged on the building wall 2 at a distance from the building wall 2. The building wall 2 is, for example, an exterior wall of a residential or other building. The facade cladding 3 is arranged, in particular, on or in front of an outer surface 4 of the building wall 2, that is, on the outside of, for example, the residential or other building.

[0022] The facade cladding 3 comprises a number of panels 5, 6, 7 arranged one above the other in a plane parallel to the outer surface 4 of the building wall 3 at a distance from the outer surface 4 of the building wall 3. The panels 5, 6, 7 are in the form of boards or horizontally arranged planks. In the exemplary embodiment, the panels 5, 6, 7 are sandwich panels with a thermal insulation layer 8 made of, for example, a rigid foam or a thermal insulation fleece and a facing layer 9 made of sheet metal, a metal or plastic foil, or plastic on an outer surface 10 of the sandwich panels or panels 5, 6, 7 facing away from the building wall. The panels 5, 6, 7 can also have a facing layer on a rear surface 11 of the panels 5, 6, 7 facing the building wall 3.

[0023] Panels 5, 6, and 7 are arranged one above the other in the plane parallel to the outer surface 4 of the building wall 2 at a distance from the building wall 2. A panel 6 arranged above another panel 5 will hereinafter be referred to as the upper panel 6, and a panel 5 arranged below another panel 6 will be referred to as the lower panel 5, wherein each panel 5, 6, with the exception of the uppermost and the lowermost panel 7, can be both an upper panel 6 and a lower panel 5 simultaneously.

[0024] The panels 5, 6, 7 have grooves 12, 13 in their lower and upper edges 14, 15, wherein the grooves 12 in the lower edges 14 of the panels 5, 6, 7 are here referred to as lower grooves 12 of the panels 5, 6, 7 and the grooves 13 in the upper edges 15 of the panels 5, 6, 7 are referred to as upper grooves 13 of the panels 5, 6, 7.

[0025] In the upper and lower grooves 12, 13, springs 17—shaped like strips in the exemplary embodiment—are inserted, connecting the upper and lower panels 5, 6, 7 at their facing lower and upper edges 14, 15 in a tongue-and-groove joint. The springs 17 can also be short and, for example, disc-shaped. In this case, several springs 17 are preferably arranged along the length of the panels 5, 6, 7, distributed in the lower and upper grooves 12, 13, connecting the lower and upper edges 14, 15 of the stacked panels 5, 6, 7. The spring(s) 17 can also be considered, more generally, as engagement elements for engaging the grooves 12, 13 of the panels 5, 6, 7.

[0026] A long-shaft dowel 19 is inserted through a hole in the spring 17 to act as a spacer 20. Several long-shaft dowels 19 are arranged as spacers 20 at intervals along a longitudinal direction of the panels 5, 6, 7, either at or between the lower and upper edges 14, 15.

[0027] At one front end, the long-shaft dowel 19 is designed as an expansion dowel 21, which is inserted into an anchor hole 22 in the building wall 2. At one rear end of the expansion dowel 21, the long-shaft dowel 19 has a tubular hollow shaft 23, which bridges the gap between the building wall 2 and the facade cladding 3 and passes through the hole in the spring 17.

[0028] On an outer side of the spring 17 facing away from the building wall 2, the hollow shaft 23 of the long-shaft dowel 19 has a conical, funnel-shaped collar 24 at a rear end of the long-shaft dowel 19, which overlaps the spring 17 on the side facing away from the building wall 2, such that the long-shaft dowel 19, which forms the spacer 20 of the suspended facade 1 according to the invention, connects the panels 5, 6, 7 to the building wall 2 via the springs 17 in the grooves 12, 13 of the panels 5, 6, 7 in a tensile-resistant manner. The panels 5, 6, 7, or the facade cladding 3, can therefore not be moved further away from the building wall 2 than is determined by the collar 24 of the long-shaft dowel 19. In the exemplary embodiment, the expansion dowel 21, the hollow shaft 23 and the collar 24 are integral components of the long shaft dowel 19.

[0029] At their lower edges 14, the upper panels 6 overlap the long-shaft dowels 19 forming the spacers 20 of the curtain wall 1 according to the invention, such that the panels 5, 6, 7 are held at their distance from the building wall 2. This is achieved by the fact that, as shown in Figure 1 As shown, the lower edge 14 of the upper panel 6 overlaps the funnel-shaped collar 24 of the long-shaft dowel 19, the panels are also designed to withstand compressive loads; in other words, in the arrangement according to the invention, the panels cannot be pushed towards the building wall 2 when the long-shaft dowel 19 is spread in the building wall as provided.

[0030] The long-shaft dowels 19 forming the spacers 20 can generally also be considered as fasteners for the facade cladding 3 of the curtain wall 1 according to the invention.

[0031] The lowest panel 7 is arranged on one or more brackets 16, which are attached to the building wall 2 at lateral intervals and at the same height, such that they hold the lowest panel 7 horizontally. The lowest panel 7 of the facade cladding 3 of the curtain wall 1 according to the invention is here defined as the panel 7 under which no other panel 5, 6, 7 is located, or at least no panel 5, 6, 7 that is connected by a tongue 17 in the lower groove 12 in the lower edge 14 of panel 7 to a panel 5, 6, 7 arranged below it. The lowest panel 7 is also simultaneously a lower panel 5.

[0032] The panels 5, 6, 7 of the facade cladding 3 support each other and, via the lowest panel 7, rest on the consoles 16.

[0033] In the exemplary embodiment, the brackets 16 are support brackets with sufficient stability to support the facade cladding 3. The brackets 16 are arranged on the building wall 2 so that their height is adjustable, allowing for height adjustment and vertical or horizontal alignment of the facade cladding 3.

[0034] On the consoles 16, L-shaped profile strips 18 are arranged, which engage in the lower groove 12 of the lowest panel 7 of the facade cladding 3 and whose distance from the building wall 2 is adjustable such that the distance of the lower edge 14 of the lowest panel 7 of the facade cladding 3 from the building wall 2 is adjustable.

[0035] Thus, the console 16 has a height adjustment and a distance adjustment for the lowest panel 7 of the facade cladding 3 of the curtain wall 3 according to the invention.

[0036] Figure 2Figure 1 shows a threaded rod 25 as an alternative to the long-shaft dowel 19. The threaded rod 25 is anchored in the anchor hole in the building wall 2 with mortar, adhesive, synthetic resin, or the like, and passes through the spring 17. Nuts 26 are screwed onto the threaded rod 25 on both sides of the spring 17 such that the spring 17, and via the spring 17 the panels 5, 6, 7 or the facade cladding 3, are held at their distance from the building wall 2. In this embodiment of the invention, the threaded rod 25 forms the spacer 20, or more generally, the fastener that holds the panels 5, 6, 7 or the facade cladding 3 at their distance from the building wall 2. The thermal insulation layer 8 and the cover layer 9 of the upper panel 6 cover the threaded rod 25, which forms the spacer 20, on the outside 10.

[0037] To fasten the facade cladding 3 of the curtain wall 1 according to the invention to the building wall 2 at the specified distance from the building wall 2, the brackets 16 are first attached to the building wall 2 and adjusted to the same height. For horizontal alignment, the bottommost panel 7 can be placed onto the brackets 16. The bottommost panel 7 is inserted with its lower groove 12 onto the L-profile strip 18 on the brackets 16, and the distance from the building wall 2 is adjusted.

[0038] The spring 17 is inserted into the upper groove 13 of the lowest panel 7, and the long-shaft dowel 19, forming the spacer 20, is inserted through the hole in the spring 17 and, with its expansion dowel 21, is inserted into the anchor hole 22 in the building wall 2. The distance from the building wall 2 is adjusted by axially sliding the long-shaft dowel 19, whereby the expansion dowel 21 of the long-shaft dowel 19 is not yet expanded.

[0039] After the distance has been set, the expansion plug 21 of the long-shaft anchor 19 is expanded by screwing an expansion screw (not visible in the drawing) into the anchor hole 22 in the building wall 2, thereby anchoring it in the building wall 2. The expansion screw can already be in the long-shaft anchor 19 during the distance setting, but not yet screwed in far enough to expand the expansion plug 21. Alternatively, the expansion screw can be inserted into the long-shaft anchor 19 only when it is ready for expansion. If the spacer 20 is designed as a threaded rod 25, as described above, the distance is adjusted, or rather, the set distance is fixed, using the nuts 26. Once the desired distance is reached, the nuts 26 simply need to be tightened against the spring 17.

[0040] According to the invention, after the spacing has been adjusted and the long-shaft dowel 19, forming the spacer 20, has been anchored in the building wall 2, an upper panel 6 with its lower groove 12 is placed onto the tongue 17 and positioned on the lowermost panel 7. The upper panel 6 overlaps the long-shaft dowel 19 at its lower edge 14, thereby fixing the distance of the panels 5, 6, 7 from the building wall 2.

[0041] In the manner described above, the other panels 5, 6 are placed one after the other, a tongue 17 is inserted into the upper groove 13 in each case, and the distance from the building wall 2 is adjusted using long shaft dowels 19 or threaded rods 25, and the panels 5, 6 are fastened to the building wall 2 at the set distance.

[0042] In the following explanations of the further embodiments of the invention, the differences from the one described above and in Figure 1The illustrated embodiment of the invention is explained, and the details regarding Figure 1 referred to.

[0043] The in Figure 3 The illustrated embodiment of the invention uses a mounting bracket 27 as a spacer 20. A first leg 28 of the mounting bracket 27 is screwed to the building wall 2 by means of a fastening screw 34, and a second leg 29 of the mounting bracket 27 projects from the building wall 2. On the second leg 29 of the mounting bracket 27, a block, for example cube-shaped or cylindrical, is arranged as a spring 17 at an adjustable distance from the building wall 2. The block forming the spring 17 is fastened, together with the lower panel 5, to the mounting bracket 27, which forms the spacer 20, by a screw 30 that passes through the second leg 29 of the mounting bracket 27 and is screwed into the lower panel 5 from above.

[0044] After adjusting the distance between the block forming the spring 17 and the upper edge 15 of the lower panel 5, the upper panel 6, or one of the upper panels 6, is placed on the second leg 29 of the mounting bracket 27 forming the spacer 20, which projects from the building wall 2, such that the lower groove 12 is placed on the spring 17, thereby positioning the lower edge 14 of the upper panel 6 at the specified distance from the building wall 2.

[0045] As in the first one, in Figure 1 The illustrated embodiment of the invention also extends to the third, in Figure 3 In the illustrated embodiment of the invention, the upper panel 6 of the facade cladding 3 has the spring 17 on the outside 10 of the panels 5, 6, 7 or on the outside 10 of the facade cladding 3.

[0046] In the fourth, in Figure 4In the illustrated embodiment of the invention, profiles 31 are screwed or otherwise fastened to the rear side 11 of the panels 5, 6, 7, which faces the building wall 2, near the upper and lower edges 14, 15 of the panels 5, 6, 7. The profiles 31 can be strip-shaped and narrow in the longitudinal direction of the panels 5, 6, 7, and in this case, several profiles 31 are arranged side by side at intervals on the rear side 11 of the panels 5, 6, 7. The profiles 31 can also be continuous in the longitudinal direction of the panels 5, 6, 7.

[0047] The profiles 31 are cranked, they have a contact section 32 arranged on the rear side 11 of the panels 5, 6, 7 and a clamping leg 33 pointing towards the lower or upper edge 14, 15 of the panels 5, 6, 7 at a distance from the rear side 11 of the panels 5, 6, 7 corresponding to the thickness of the spring 17. These clamping legs 33 of the profiles 31 form the upper and lower grooves 12, 13 on the upper and lower edges 14, 15 of the panels 5, 6, 7 of the facade cladding 3 of the curtain wall 1 according to the invention.

[0048] The springs 17 are like... Figure 1 described with a fastener or spacer 20 - in the exemplary embodiment with a long-shaft dowel 19 - arranged at a distance from the building wall 2 on the building wall 2. Also as described above. Figure 1As described, the panels 5, 6, 7 are arranged at a distance from the building wall 2 by placing their upper and lower grooves 12, 13, which are arranged on the rear sides 11 of the panels 5, 6, 7 with the help of the profiles 31, onto the tongues 17.

[0049] The distance setting is also done in Figure 4 how to Figure 1 described by axial displacement of the long shaft dowels 19 in the anchor holes 22 in the building wall 2, while the long shaft dowels 19 or their expansion dowels 21 are not yet expanded, and subsequent expansion of the expansion dowels 21 of the long shaft dowels 19 in the anchor holes 22 in the building wall 2.

[0050] At the Figure 5In the illustrated variant of the invention, the profiles 31, which form the lower grooves 12, are arranged only near the lower edges 14 of the upper panels 6, and the springs 17 are screwed or otherwise arranged to the rear sides 11 of the lower panels 5, projecting upwards beyond the upper edges 15 of the lower panels 5. The long-shaft dowels 19 are passed through holes above the upper edges 15 of the lower panels 5 of the springs 17 and inserted into the anchor holes 22 in the building wall. Figure 4 as well as in Figure 5 The upper panels 6 overlap at their lower edges 14 the long shaft dowels 19 forming the spacers 20 on the outside 10 in such a way that the panels 5, 6, 7 are held at the distance from the building wall 2.
