Supporting framework for a facade

Abstract

A framework for a facade is constructed from adjacently arranged flat facade elements such as glass panes, decorative panels or the like and comprises profiled supports. The profiled supports are formed from retaining bars which are parallel to the facade surface and from webs which are approximately perpendicular to the facade surface. The retaining bars and the webs are essentially flat material strips. At least one web has a projection which is provided as a single piece with the web and which projects into an insertion opening in a retaining bar. A retaining device is provided on the projection for fixing the facade element and has at least one pin-shaped or bolt-shaped part. This part is arranged in such a manner that it is secured on the projection of the web by the retaining bar.

1 . A supporting framework for a facade formed from flat facade elements such as glass panes, decorative sheets or the like that are arranged adjacent to each other, with sectional supports comprising retaining bolts arranged parallel with a surface of the facade and struts perpendicular to the facade surface, wherein the retaining bolts and the struts are essentially flat strips of material, and wherein at least one of the struts have a projection which is designed integral with the strut, and which projects into a plug-in opening in one of the retaining bolts, a retaining device provided on the projection for fixing the facade element, which device comprises at least one pin- or bolt-shaped component and this component is arranged so that the component is secured by the retaining bolt to the projection of the strut  
   
   
       2 . The supporting framework according to  claim 1 , wherein the projection has a retaining groove and is provided with a head which is arranged in the retaining groove.  
   
   
       3 . The supporting framework according to  claim 2 , wherein the retaining groove formed in the projection runs in the plane of the retaining bolt.  
   
   
       4 . The supporting framework according to  claim 3 , wherein the height (h) of the projection is smaller than the thickness (d) of the retaining bolt.  
   
   
       5 . The supporting framework according to  claim 1 , wherein the cross-section of the projection is roughly equivalent to the cross-section of the plug-in opening.  
   
   
       6 . The supporting framework according to  claim 2 , wherein the retaining groove runs transversely to the plane defined by the strut.  
   
   
       7 . The supporting framework according to  claim 2 , wherein a slot is formed in the projection, through which slot projects the component.  
   
   
       8 . The supporting framework according to  claim 2 , wherein the retaining groove has a cross-sectional shape which corresponds essentially to an isosceles triangle and the head of the component is conical.  
   
   
       9 . The supporting framework according to  claim 2 , wherein the cross-sectional shape of the retaining groove is semicircular, and the head of the component is hemispherical.  
   
   
       10 . The supporting framework according to  claim 2 , wherein the cross-sectional shape of the retaining groove is essentially rectangular, and the head of the component is cylindrical.  
   
   
       11 . The supporting structure according to  claim 1 , wherein the retaining device is displaceable to a limited degree on the projection and/or can be swivelled to a limited degree.  
   
   
       12 . The supporting structure according to  claim 1 , wherein the projection is fixed in the plug-in opening.  
   
   
       13 . The supporting structure according to  claim 12 , wherein the projection is fixed in the plug-in opening by welding or gluing.
