20090039042 | Assembly System - 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. | 02-12-2009 |
