<p>The steel skeleton frame support in a light steel structure, is a U-sectioned profile unit, comprising two overlapping parts. One part (1) has a hole (5) in the overlap section, and a nearby concentrically curved lengthways slit (6), and the other part (7) hs a lengthways slit (11) and cross slit (12) in the rear. The two rears (2, 8) are pressed together by a female screw (14) passing through the hole in one part and lengthways slit in the other, and through a washer (16). The washer is welded to the screw head (15), and has a parallel bolt (17) welded to it, passing through a curve slit and cross slit. Foundation level variations can be easily compensated.</p> |
