Description

cladding structure

technical field

The invention relates to a facade cladding structure for suspending panel elements inserted into a facade structure, said structure comprising an upper structural element and a lower structural element interconnected by structural elements on both sides, and at least one The upper and lower suspension brackets are fixedly installed on the surface, and the lower suspension bracket has an adjacent surface of a support structure. The clamping part is elastically loaded towards the first position, the clamping part is displaceable against the elastic load and can move from the first position to another position, and the clamping part is in another position closer to the structure than in the first position.

Background technique

German Patent No. DE 196 03 433 describes a device for providing temporary holding force when panel elements are suspended from a façade. The panel elements are mounted directly or inserted into the structure between retaining elements arranged on the façade, the lower edge of said element resting against the lower retainer so that its upper edge swings under an upper retainer, one wedged into the element The elastic element of the upper edge engages with the upper holder and temporarily holds the element. The elastic element is a thin steel sheet bent into an acute-angled shape and clamped to the upper edge of the panel element in such a way that, viewed in the longitudinal direction of the upper edge, it forms a V-shaped element, a strut of which Clamped to the upper edge of the panel element and the other strut has a free end projecting obliquely upwards with respect to the upper edge and facing the façade away from the side of the panel element. When the upper part of the panel element swings below the upper retainer, the free strut of the elastic element is first pressed down by the protrusion protruding downward from the retainer, and the strut springs upward at the rear of the protrusion, thereby temporarily pulling the upper The edges remain in place. For final retention of the panel elements, final retention brackets are mounted by bolts on the outer sides of the upper and lower holders, the brackets protruding above the panel elements and holding them in position. Finally, the bolts are concealed in the final retaining bracket by extrusion-molded covers.

However, in the known arrangements, it is disadvantageous that the suspension of the panel elements on the façade is time-consuming, especially since the final clamping of the elements is by means of bolts and subsequent mounting of the molded cover. It is especially disadvantageous that the disassembly of the panel element is very problematic, since the elastic element is relatively difficult to reach and is even hidden in the gap between the upper edge of the panel element and the upper holder, so for the purpose of disengaging from the engagement with the holder , the compression of the components is almost impossible, even with a suitable tool.

Contents of the invention

The object of the present invention is to provide a facade cladding structure for installation on a facade, the installation and disassembly of the structure are both simpler and faster than the existing structures.

With this in mind, the façade cladding structure of the present invention is characterized in that the elastic element is shaped like an elongated band along one of the structural elements, said band is connected to the structure at one end, the snap part is provided at the other end of the band, and The lower suspension brackets have means to hold the lower part of the structure against displacement in a direction approximately perpendicular to the façade.

This allows for simple final clamping of the façade cladding structure to the façade in just one operation by supporting the lower part on the abutment surface of the lower suspension bracket and then swinging the upper part of the structure inwards towards the upper suspension bracket It is possible that the snapping portion of the elongated strap is pressed against the structure to pass under the upper suspension bracket and that the snapping portion eventually springs back into its final snapping state with the bracket.

In the upper part of the structure as a follow-up of the elongated shape belt and its installation along the structural element, the subsequent installation of the final clamping without additional holding brackets is made possible by means of a belt-shaped elastic element, in this way, thanks to this The high elastic force can be balanced out during installation, the strap can be designed with the necessary elastic force for the final hold, due to the elongated shape and the positioning of the strap it is designed to be manually pressed, the card can be snapped in by hand or with a suitable tool It is possible to press the holding part in the direction of the structure.

Final holding in the lower part of the structure is ensured by the adjoining faces of the lower suspension brackets and the means for holding this part of the structure in the direction outwards from the facade. Removal of the structure is as simple as installation, since the snap-in part of the strap can easily be pressed out of the snap-in with the upper suspension bracket, for example, by inserting a suitable tool from the front of the structure, i.e. by elongating the strap side.

In a preferred embodiment, the elongated strap is bent from a flat elastic strap such that one end of the strap forms a clamping portion that is clamped flat against the structure, and the other end of the strap constitutes a snapping portion, and the clamping portion The engaging portion and the engaging portion are connected to each other through an intermediate portion, and an obtuse angle is formed between the intermediate portion and the clamping portion. This makes it possible in a simple manner to obtain a suitably high elastic force holding the structure on the façade, since the part of the strip protruding from the structure is elastically deformed by pressing the catch against the structure.

In an advantageous embodiment, the catch of the strap forms a top facing away from the structure and is formed by bending the elastic strap. This ensures a definite engagement of the catch of the strap with the suspension bracket, a more stable holding of the structure on the façade is obtained due to the fact that the catch has a limited width in the longitudinal direction of the strap, so that the structure does not To move, for example under the influence of wind.

At its snap part, the strap can have an indentation facing away from the structure, which is formed by bending the elastic strap. The indentation forms a stable abutment for a tool, such as a screwdriver, that can be used to press the catch of the strap against the structure during mounting and dismounting of the structure.

In addition, the strap can have a free end bent away from the structure at the catch. Said free strap end may protrude slightly from the end of the suspension bracket facing away from the structure, through which the suspension bracket and the strap are mutually joined, and the free strap end then forms an easy detachable and for the above-mentioned purpose for pressing the strap during the dismantling of the structure. Tools are especially suitable for abutment.

In an advantageous embodiment, the upper suspension bracket has a recess for accommodating the engaging part of the elongated strap, said recess being formed by a bottom and two side walls, having a conical cross-section so that the two sides of the bottom The distance between the side walls is smaller than the width of the engaging portion, and the opposite bottom is larger than the width of the engaging portion. Where the flat strip engages lengthwise with the groove, the edge of the strip is wedged between the two side walls of the groove, so that a particularly stable engagement is achieved, thus resulting in a better retention of the structure.

In a more preferred embodiment, the lower suspension bracket has two opposing abutment surfaces for mounting approximately parallel to the façade, after the structure has been suspended approximately parallel to the façade, corresponding to those on the lower part of the structure. The upper and lower abutment surfaces of the abutment surfaces abut and are tucked between the abutment surfaces of the suspension bracket. This prevents displacement of the structure parallel to the façade after suspension, while it compensates for any inaccurate installation of the suspension brackets on the façade, both horizontally and vertically.

In an advantageous embodiment in terms of manufacture, all structural elements have the same cross-section and are made by extrusion, the upper and lower abutment surfaces of the lower part of the structure being formed by flanges formed on the extrusions of the structural elements.

The structure may also have a circumferential bead facing each other when the structure is installed, said bead protruding below the protrusion of the lower suspension bracket. This ensures that further upward displacement of the structure is prevented.

The upper hang bracket may also include a support block of resilient material for abutting against the circumferential bead on the structure so that the upper hang bracket may be held in place for the belt to snap into place in the groove of the hang bracket. Correct positioning. Moreover, the final suspension is also more stable.

Detailed ways

Figures 1 and 2 show a facade cladding structure 1 comprising an upper structural element 2, a lower structural element 3 and two side structural elements 4, not shown in the figures. The structural elements 2 , 3 , 4 are all cut from extruded aluminum profiles with the same cross-section and mitered to form a rectangular structure 1 . A panel element 5, such as a window panel, is inserted into the opening of the structure, the panel element 5 being held in the flange 6 of the structure 1 and the panel molding 7 mounted on the structure. It is worth noting that the structure in the figure is divided in the middle and its overall height is not shown.

Fig. 2 shows the facade cladding structure 1 installed on a building facade 8, by screws, not shown, the upper suspension bracket 9 and the installation of each upper corner of the structure 1 installed on the facade Lower suspension brackets 10 at each lower corner of the structure 1 .

The lower suspension bracket 10 has a flat mounting portion 11 which is mounted completely against the facade by screws, not shown. A flange 12 with a hook-shaped cross-section protrudes from the straight mounting portion 11 to form a U-shaped groove 13 opening upward. The flange 14 protruding downwards from the lower structural element 3 of the structure 1 is inserted into the groove 13 so that its lower edge 15 bears against the bottom 16 of the groove 13 and has an abutment surface 17 facing away from the facade 8, which The abutment surface abuts against the side wall 18 of the groove 13 in the lower suspension bracket 10 facing the façade 18 . Furthermore, the lower structural element 3 of the structure 1 bears against a projection 19 formed on the lower suspension bracket 10 above the flange 12 . Moreover, the lower structural element 3 has a longitudinal bead 20 protruding towards the facade 8, in the installed condition of the structure, the protrusion 19 protrudes from the lower suspension bracket 10 and is positioned slightly below it, whereby it is possible to A certain tolerance can be obtained in the vertical direction during installation without the structure 1 being fastened against upward displacement, for example as a result of wind, the bead 20 will prevent the structure from being raised beyond the lower suspension bracket due to the abutment against the protrusion 19 Rack 10.

At each end, the upper structural element 2 of the facade cladding structure 1 is provided with an elongated, elastic band 21 to engage with a recess 22 formed on a flange 23 opening downwards from above. The upper edge of the straight mounting portion 24 of the suspension bracket 9 extends horizontally outward. FIG. 4 shows a side view of an elongated strap 21 bent from an anti-corrosion elastic strap, which appears to have a flat clamping portion 25 with mounting holes 26 are intended to be clamped by blind rivets, not shown, horizontally against a profiled surface 27 of the upper structural element 2 , said profiled surface 27 being horizontally upwards above the installation position of the structure 1 . At one end of the clamping section 25, the flat strip has a bend 28 so that the strip forms an obtuse angle between the clamping section 25 and an intermediate section 29 which extends obliquely away from the surface 27 of the structural element 2 and, opposite the clamping section 25 , is bent at right angles downwards towards the surface 27 , thereby forming a top facing away from the structural element 2 to constitute the catch 30 for the strap 21 . After the top 30 there is also a right angle bend in the opposite direction, thereby forming an indentation 31 for the structural element 2 engaged with the installation tool. The structural element 2 is bent and forms an abutment for the installation tool. FIG. 6 shows a schematic view of the strap 21 , and FIG. 5 shows a schematic view of the strap 21 mounted on the upper structural element 2 .

A strip 21 is installed longitudinally along the structural element 2 and can be seen from one end of FIGS. 1 and 2 when and after installation of the structure 1 to the façade 8 , respectively. FIG. 3 also shows a cross-section through the suspension bracket 9 parallel to the facade 8 in the engaged state of the belt 21 and the upper suspension bracket 9 , the facade cladding structure 1 being indicated only by dashed lines. The facade cladding structure 1 is suspended on the facade 8 by positioning the structure in the position shown in FIG. Snapping, the structure is inclined outwards from the facade 8 . The structure 1 with the upper structural part 2 is then swung inwardly towards the upper suspension bracket 9, the catch 30 of the elastic band 21 is pressed down towards the structural element 2, and the band is clamped by hand, or with a tool, such as a screwdriver. Tighten and engage with the upper notch 31 of the strap. It can thus pass the first side wall 33 of the lower groove 22 in the flange 23 of the upper suspension bracket 9 . Thus, the structure 1 with the upper structural element 2 can swing below the flange 23 , the catch 30 of the strap is located below the groove 22 , the elastic strap 21 is released so that the catch moves elastically upwards in the groove 22 .

Corresponding to the first side wall 33, the groove 22 has a second side wall 34, which is inclined relative to the first side wall 33, so that the width of the groove 22 is wider at the bottom 35 than the catch 30 of the belt. Slightly narrower, the width at the opening of the groove 22 is slightly wider than the width of the engaging portion 30 , so the engaging portion 30 is wedged into the groove 22 when the belt 21 elastically moves upward. Because at the same time the catch 30 has a short length in the longitudinal direction of the groove 22, the strap 21 fixes the structure 1 in the upper suspension bracket 9 in a very stable manner. It can be seen from FIG. 1 and FIG. 2 that in the installation position of the structure, the elastic band 21 is elastically bent downward relative to the untensioned state in FIG. 1 , so the engaging portion 30 is held in the groove 22 .

The dimensions of the lower structural element 3 and the lower suspension bracket 10 of the structure 1 are larger so that when the upper structural element 2 is swung into its installation position, the lower structural element 3 is wedged into the lower suspension bracket 10, the hook flange The abutment face 18 on 12 is pressed against the abutment face 17 on the lower structural element 3 and the lower structural element 3 is pressed against the protrusion 19 of the lower suspension bracket 10 . Before wedging, the lower structural element 3 can be freely displaced in the horizontal groove 13, which can be seen from FIG. The structure 1 is thus adjustable laterally relative to the façade 8 before final installation, which makes it possible to compensate for inaccurate installation of the lower suspension bracket 10 in the transverse direction of the structure.

And, on the outside of the flat mounting part 24 of the upper suspension bracket 9, an elastic block is installed, such as the rubber block 36 of the upper circumference bead 20 of the opposite structure 1, when the structure swings to its installation position, the bead The shape is pressed into the rubber block 36, as shown in FIG. 2, thus further stabilizing the suspension of the structure 1 on the facade 8.

It is as easy to install the upper suspension brackets 9, 10 as the structure 1, and the structure can also be dismantled, because the snap part 30 of the belt is simply pressed out of the groove 22 of the upper suspension bracket 9, so there is an upper structural element 2 The structure swings away from the suspension bracket 9 and is lifted away from the combination with the lower suspension bracket 10 . In order to press down on the snap-fit portion 30 of the strap, it is necessary to use a suitable tool, such as a screwdriver, which is inserted over the upper edge 37 of the upper structural element 2 of the structure and engages with the outer free end of the strap 21, which tool Tabs 32 are held in position relative to the belt or may engage upper indentations 31 by the outward bending. The tool is thus better held in position relative to the strap 21 , while by elastic displacement of the strap the catch 30 is forced out of engagement with the groove 22 to disengage the structure 1 . Requiring a small gap between the upper edge 37 of the structure and the lower edge of the mounted structure to allow the above-mentioned disassembly by tool insertion, several structures 1 can be assembled relatively close to each other. The distance between the structures arranged one above the other can be, for example, 8-15 mm.

Although the façade cladding structure 1 is shown mounted on a vertical façade 8, it is obvious that the structure 1 of the present invention can also be mounted to an inclined façade. It can also be seen from the figure that the installation position of the structure on the facade, the upper and lower suspension brackets 9, 10 and the installation spring 21 are hidden by the circumferential flange 38 of the structural elements 2, 3, 4, which is aesthetically is an advantage.

In general, two upper suspension brackets 9 and two lower suspension brackets 10 are applied, the brackets being positioned at the corners of the structure, for example also at the position of the side structural elements 4 of the structure, more for large structures. Multiple bays are advantageous. The side structural element 4 can be provided with an elastic band 21 for engaging with a bracket corresponding to the upper suspension bracket 9 .

Obviously, the elongated strap 21 can be designed in another way than shown; the catch 30 can, for example, consist of an elongated flat part of the strap, which can also be designed so that one end is hinged to the structure 1 and is elastically loaded to swing out of the structure, for example by torsion springs or compression springs.
