In the outer area of the Supporting arm 1 are at the bottom of the support arm further two angle parts. 7 attached, each having two mutually perpendicular legs 8, 9. To attach the angle parts 7 is in the parallel to the bottom of the Tragarmes 1 lying leg 9 a threaded bore 10 is provided in the a passing through a slot 11 in the support arm screw 12 can be screwed. The contiguous surfaces of the support arm 1 and the leg 9th are toothed, so that the angle part 7 by tightening the screw 12 in the different predetermined by the teeth locking positions form fit against a shift can be secured.

The leg 8 of the angle part 7 is located at an upper part of the abutment leg. 6 spaced opposite. The legs 8 and 9 of the angle part 7 and in this upper part of the abutment leg 6 lying, parallel to the leg 8 extending Investment area 13 of the plant leg 6 form a total of one after bottom open, U-shaped receptacle 14 for the upper horizontal edge 15 a Glass panel 16. The width b of this photograph is the extent of the longitudinal extent the elongated hole 11 adjustable.

In the receptacle 14 is a U-shaped damping member 17 made of an elastic Material arranged on the surface of one of the side cheeks, for example the contact area 13, the U-shaped receptacle 14 is glued. Of the Base leg of the damping member 17 has a folded portion 18 with a reduced wall thickness, which is adapted to different Widths of the recording 14 can be pulled apart like an accordion.

The contact area 13 is connected to the support arm 1 via a bend, making room for a sufficiently long leg 9 of the angle 7 for Plant on the underside of the support arm 1 is created. About another, at the contact area 13 downwardly adjoining bend in the plant leg. 6 is the upper contact area 13 with a second, lower and further outward Attachment area 19 connected to a side cheek of a second, after forms open at the top, U-shaped receptacle 20. The base of this open-topped Pickup 20 is from a right angle to the investment area 19, outwardly directed support web 21 formed at the free end of the Investment leg 6 is formed. At the bottom of the support web 21 is a Leg 24 of an angle portion 22 attached, wherein in the support web a threaded bore 25 is arranged in the one through a slot 26 in the leg 24th passing screw 27 is screwed.

For the production of a complete glass facade further holders are used, as shown in Figures 3 to 7. At the top of the top Series of glass panels 16 of the facade is not an upwardly open receptacle for Retaining the lower edge of a glass sheet more necessary. Here is a holder can be used according to FIG. The plant leg 6 'ends in this case immediately below the upper contact area 13.

Similarly, at the bottom of the bottom row of glass panels Holder can be used, as shown in Fig. 6. This holder is identical to the one in Fig. 1 and 2 shown, except that on the underside of the support arm 1 no angle parts 7 are screwed and of course the respective damping parts 17 are omitted.

The holders described so far were each for two laterally adjacent Designed glass panels. On the side edge of the facade are instead of in the Figures 1, 3 and 6 shown in the holder shown in Figures 4, 5 and 7 Holder can be used. These holders are each a single, down and / or top open receptacle provided. It can therefore be a narrower one Support arm 1 'can be used, otherwise the structure of this holder is analogous to that of the previously described. Ends the glass facade on an outside corner of the Building on which one faces the other areas of the building If there is increased wind pressure, instead of that shown in FIGS. 4, 5 and 7 Training preferred a correspondingly broader training of the holder, wherein a support arm 1 may be provided, as shown in Figures 1, 3 and 6 is, and the individual up and / or down open shots can extend over the entire width of this support arm 1.

In all embodiments of holders shown, the support arm 1, 1 'each over a mounting bracket 2 connected to a post 4. For exact adjustment the distance of the glass facade from the upright 4 is the support arm 1 opposite the support leg 31 of the mounting bracket slidably. These are in the Support arm 1,1 'long holes 32 provided through which the threaded holes in the support leg 31 screwed screws 3 range. The top of the The support leg 31 is further formed serrated, as well as the adjacent thereto Bottom of the support arm 1. When tightened screws 3 is thereby a positive engagement with respect to a displacement between the support arm. 1 and the support leg 31 given.

For mounting a glass panel, the angle pieces 22 of the holder are first with intended for receiving the lower horizontal edge 29 of the glass sheet 16, unscrewed upwards receptacles 20 of the support webs 21. Of the upper horizontal edge 15 of the glass sheet 16 is in the downwardly open shots Inserted 14 of the corresponding overlying holder, wherein the lower portion of the glass sheet still outside the support web 21 of the underlying Holder is. Is the upper horizontal edge correspondingly far into the recordings 14 inserted, the lower horizontal edge 29 can be pivoted inwards and on the corresponding support web 21 and the on it arranged damping members 28 are discontinued. As a result, the Angle parts 22 of the upwardly open receptacles 20 screwed. For fixing the glass sheet 16 are finally the angle parts 7 of the downwardly open Shooting and the angle parts 22 of the upwardly open shots when open Screws 12, 27 braced against the glass sheet 16 and in this position fixed by tightening the screws 12, 27.
