It is known for a profiled bar to be fastened to a supporting bar such that the screw head of a screw which is passed through the supporting bar is supported on a disc which is inserted in an undercut groove of the supporting bar. In this case, the screw is screwed into a concentrically arranged chamber in the profiled bar. In consequence, it is not possible to prevent rotation nor to absorb torsional forces. In accordance with the invention, two inner chambers (5) are now provided into which screws (4, 8) are screwed, the common lateral axis of which chambers runs superimposed on the longitudinal axis of the supporting bar 1. This provides a high load capacity and also prevents rotation. …<IMAGE>… |
