BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a support anchor for façade panels with an anchor body which can be screwed to a building wall and which has a rear wall with a screw slot and has a front wall spaced therefrom. , which at its free end is connected to the facade panels by means of a transverse pin.

BACKGROUND OF THE INVENTION

Such known support anchors serve to carry, at a certain distance from the wall of the building, facade panels of natural stone, concrete or ceramics that form a suspended facade. In addition to the normal vertical and horizontal adjustment possibilities parallel to the building wall, the distance to the building wall must also be adjusted. For this purpose, a threaded bolt is screwed to the anchor body in two adjustable ways. In addition, types of embodiments are known in which the opening in the front wall is threaded into which a threaded bolt is screwed in an adjustable manner.

In order to achieve a wide range of spacing between the suspended facade and the wall of the building without the large free protruding threaded stud sections being too large, different anchor bodies can be provided which differ in the distance between the rear and front walls.

In the known carrier anchor of the initially mentioned type (Dubelankersystem 4 from Lutz Ankersysteme GmbH & Co. KG), the anchor body consists of a multi-folded flat material.

A horizontal flange protrudes from the lower edge of the rear wall lying on the wall of the building, to the front side of which the front wall faces downwards. Its lower edge is connected to a horizontal flange that points back to the building wall. In order to allow the vertical loads exerted by the weight of the façade panels and the threaded bolt, together with the bending stresses resulting therefrom, to be transmitted from the front to the rear wall and thus to the building wall, a relatively thick flat material has to be used. This places considerable demands on production and increases the weight of the support anchor. This is particularly true for those embodiments in which a relatively large distance is provided between the rear and front walls, that is to say with anchor bodies lined relatively far.

of

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a support anchor of the type mentioned above so that it is lightweight and relatively easy to manufacture with relatively low production costs.

SUMMARY OF THE INVENTION

According to the invention, this is accomplished by a support anchor for façade panels with an anchor body which can be screwed to a building wall and which has a rear wall with a slot on the groove and has a front wall spaced apart therefrom in which the opening comprises a length adjustable with a thread which is connected at its free end by means of a transverse bolt to the facade panels, the essence of which is that the anchor body is made of sheet metal and that the two perpendicular side edges of the rear wall connected to the two perpendicular side edges of the front wall.

The transmission of the vertical load and bending stress between the front wall and the rear wall by means of two parallel sidewalls allows the anchor body to be made of low material cost with the supporting anchor.

relatively thin sheet. S achieves high load-bearing capacity

The anchor body is preferably constructed of a one-piece sheet metal blank by parallel bending, the opposing side edges of the sheet metal blank lying on the BObé to form a rear or front wall. The production costs required here are very small, in particular for machining the sheet metal blank, only simple bending processes are required, in particular only small tools, simple tools and small forming forces are required, especially in the case of possible small sheet thicknesses. Joining the two lateral edges of the sheet blank by welding or otherwise is unnecessary because the two arms in the region of the rear or front wall are superimposed; that's enough to connect.

The anchor body formed in this way has the shape of an open box at the top and at the bottom which, due to its shape strength, provides a high load-bearing capacity even when using relatively thin sheet metal.

In the design of the support anchor in which the threaded bolt has an adjusting nut behind the front wall and a lock nut in front of the front wall that tighten against each other to secure the threaded bolt after its length adjustment, access to the box as an box could affect access to the set nut.

Therefore, in a further embodiment of the idea of the invention, it is contemplated that the set nut has grooves at least at its rear edge, away from the front face. This knurling allows the adjusting nut to be rotated by inserting a finger up or down into the anchor to perform the desired length adjustment. Then the lock nut, which is always designed as a hexagon nut, is tightened from the front.

** · · · **

The adjusting nut is preferably an annular thread with a grooved rear edge. Instead, the adjusting nut can also be a hexagon nut with a knurled back edge.

In relatively flat support anchors, it is preferred that the threaded bolt is screwed into the threaded hole in the front wall. This embodiment is preferably achieved in accordance with the invention in that the front wall is welded to both front edges of the sidewalls. The front wall is preferably a nut that is welded to both lugs, preferably a hex nut. The production costs required for this are relatively low.

Other preferred embodiments of the invention are the subject of further subclaims.

According to an embodiment of the invention

The support anchor 1 shown in FIGS. 1 and 2 serves to support the dashed façade panels 2 in order to form a suspended façade in front of the wall 2 of the building. The anchor body of sheet metal is fixed by means of a screw 3 to the wall 3 of the building, for example by means of a dowel, to anchor rails or to a steel substructure, and carries a horizontal threaded bolt 3. A rounded mandrel 7 is inserted through the flattened end 6a of the threaded bolt 3, which fits into the side openings in the facade panels 2.

The anchor body 4 has a rear wall f1 which is fixed to the building wall 2 and which has at its upper part a perpendicular slot 5a. through which screw 3 passes ·

From the two perpendicular side edges Sa, the rear walls (6 project away two side walls 5, which are arranged parallel to each other at a certain distance from each other. The side walls 2 project at right angles to the rear wall g. 10.

• · · · <v ··

2 and 3, the armature body 4 consists of a one-piece sheet metal blank 11 as shown in FIG. 6. The two opposing side edges 11a of the sheet metal blank 11 lie on top of each other and form a front wall 10. The lower edge 10b of the front wall 10 and the lower edge 8b of the rear wall 3 lie approximately at the same height. The upper edges 9a of the two sidewalls 8 descend obliquely from the upper edge 8c of the rear wall 3 To the upper edge 10c of the front wall 13 ·

In the front wall 10 there is an opening 13 / through which a threaded bolt 3 passes. The threaded bolt 3 carries a washer 13 and a set nut 10 on the back of the front wall 10, which is designed as an annular ring (FIG. 4) provided with a threaded hole 15, the back edge 16 of which is grooved. On the front side of the front wall 13, the threaded bolt 3 carries a washer 17 and a lock nut 18, which is designed as a hexagonal nut.

To fine adjust the distance between the building wall 3 and the facade panels 2, the adjusting nut 14 is rotated by hand. To do this, it is sufficient to reach with the finger on the knurled trailing edge 13 'to allow the adjusting nut 14 to rotate.

As can be seen from FIG. 1, the rear wall 3 has in its lower part a section 8d which extends towards the wall 3 of the building. As a result, it is ensured that, even with unevenness on the wall 3 of the building, it is ensured that the support anchor 1 is supported at the lower end of its rear wall 3 against the wall 3 of the building.

The armature body 1 shown in Fig. 5 differs from the armature body 4 described previously and shown in the same way in Fig. 3 in that the rear wall 3 is formed by two side edges 11a 'of a sheet metal blank 11 lying on top of each other. An anchor body comprises a portion of a sheet blank 11 'forming a front wall

10. lies in the central region of the sheet blank 11.

Since both the anchor bodies 4 and 4 have substantially the same external dimensions, the two sheet metal cuttings 11 fit together without waste so that the anchor body 4a 4 can be produced from the sheet metal without the shavings except for the openings.

7 and 8 differs from the anchor 1 shown in FIGS. 1 and 2 in that it is made with a smaller lining and that both side walls 2 of the anchor body 4 are welded to their front edges. a hexagon nut 18 which forms the front wall 10. The threaded bolt 5 is screwed into the nut 19 and must be rotated to adjust the length. This embodiment allows a particularly flat construction of the support anchor 1, since there may be no space for the set nut and the lock nut.

In order to take full advantage of the shallow depth of the anchor body 4, there is an opening 20 in the z ✓ rear wall 2 in the direction of the extension of the threaded bolt 5, the diameter of which is larger than the thread. The threaded bolt 2 is here far until its rear free end protrudes in case of an emergency it is even possible to make the diameter of the bolt se can be screwed into the 20V hole at the location of the recess hole 20 in the wall of the building.

FIGS. 9 and 10 show that, in the support anchor 1, the other corresponding embodiment according to FIG. 1, a sloping wedge plate 21 having an obliquely extending slope extends in the region of the screw slot 5a between the rear wall 2 and the building wall 2; cutout 22 (FIG. 10). The shoulder 22 extending on the rear wall 6 is supported on the rear edge 21 of the corrugation plate 21. By means of transverse displacement of the wedge plate 21, the height adjustment of the support anchor 1 can be performed.

In addition, it is shown in FIG. 9 that the adjusting nut 14 can also be designed as a normal nut, for example a six-nut nut.
