Assembly System

Abstract

The assembly system has several profiled bars connected to each other, each of which has at least one clamping channel open to the outside with a bottom surface and two lateral surfaces. They are connected by an elongated or angled connecting element with two opposing external clamping surfaces, at least certain sections of which are straight, and an expansion joint extending between the external clamping surfaces. The connecting element is introduced into the clamping channel, and at least one spreading element is introduced into at least one section of the expansion joint in such a way that the external clamping surfaces of the connecting element are clamped against the lateral surfaces of the clamping channel of at least one profiled bar. The lateral surfaces of the clamping channel have a first ribbing, and the external clamping surfaces of the connecting element have a second ribbing, which is transverse to the first ribbing, so that, by clamping the two ribbings together, a type of permanent cold-weld joint is produced between the lateral surfaces of the clamping channel and the external clamping surfaces of the connecting element.

1 . An assembly system comprising:
 several profiled bars connected to each other, each of which comprises at least one clamping channel open to the outside with a bottom surface and two lateral surfaces;   an elongated or angled connecting element comprising:   two opposing external clamping surfaces, at least certain sections of which are straight, and
 an expansion joint extending between the external clamping surfaces, the connecting element being introduced into the clamping channel; and 
 at least one spreading element, which is introduced into at least one section of the expansion joint in such a way that the external clamping surfaces of the connecting element are clamped against the lateral surfaces of the clamping channel of at least one profiled bar; 
   
       wherein at least parts of the lateral surfaces of the clamping channel have a first ribbing, and at least parts of the external clamping surfaces of the connecting element have a second ribbing, which is transverse to the first ribbing, so that, by clamping the two ribbings together, a type of permanent cold-weld joint is produced between the lateral surfaces of the clamping channel and the external clamping surfaces of the connecting element. 
     
     
         2 . The assembly system of  claim 1  wherein certain parts of the expansion joint are widened to create openings for the insertion of the spreading elements. 
     
     
         3 . The assembly system of  claim 1  wherein the spreading element is designed as a body-bound rivet, a grooved drive stud, or a screw. 
     
     
         4 . The assembly system of  claim 3  wherein the spreading element is made of high-grade steel. 
     
     
         5 . The assembly system of  claim 1  wherein the profiled bars and the connecting element are made of aluminum. 
     
     
         6 . The assembly system of  claim 1  wherein the connecting element is covered at the ends by an extensible terminal element, which covers the expansion joint. 
     
     
         7 . The assembly system of  claim 1  wherein the ends of the profiled bars to be connected are beveled at 45° and set next to each other at an angle, and wherein the connecting element is designed as an angle-shaped connecting element. 
     
     
         8 . The assembly system of  claim 1  wherein two profiled bars with straight ends are connected perpendicularly to each other, and at least one profiled bar comprises two opposing projecting strips, which project into the clamping channel and engage in grooves in the area of the external clamping surfaces. 
     
     
         9 . A flat frame-and-panel element comprising
 an assembly system comprising:
 several profiled bars connected to each other, each of which comprises at least one clamping channel open to the outside with a bottom surface and two lateral surfaces; 
 an elongated or angled connecting element comprising:
 two opposing external clamping surfaces, at least certain sections of which are straight, and 
 an expansion joint extending between the external clamping surfaces, the connecting element being introduced into the clamping channel; and 
 at least one spreading element, which is introduced into at least one section of the expansion joint in such a way that the external clamping surfaces of the connecting element are clamped against the lateral surfaces of the clamping channel of at least one profiled bar; and 
 a flat body supported in the profiled bars. 
 
   
     
     
         10 . The flat frame-and-panel element according to  claim 9 , wherein the flat body is a solar panel.
