scaffolding or frameworks. SUBSTANCE: the framework consists of tubular posts with horizontal and/or diagonal tie rods and associated components of the framework. One or several framework joints one above another are positioned on each tubular post with an interval, each of them has respectively four wedge- shaped bond seats of the coupling members of the tie rods by inserted wedge-shaped members. The wedge-shaped bond seats of the coupling members have a geometry differing from the section of the inserted members, and a wedge head is positioned on each end of the tube of the diagonal tie rod, it is made for fit on the wedge-shaped seat with an adjoining to the tubular post and fixing by the wedge through the wedge head and wedge seat. The inserted wedge-shaped coupling members have a caved-in surface on their front and rear wedge surfaces of the intersecting sides. EFFECT: modified constructional members of the framework. 12 cl, 16 dwg |
