摘要

Supporting framework system consisting of removably connected longitudinal (1) and transverse bars (2) with a square cross-section comprises a node element (7), and adapter screws (11) screwed into the node element in a plane orthogonal to each other and inserted and axially fixed with one section in the end openings in the transverse bars. The node elements lie within a longitudinal bar into which at least one adapter screw is screwed through a continuous bore (6) in the longitudinal bar wall. Preferred Features: The adapter screw guides a bushing (15) which is fixed on the longitudinal bar wall by a pressure nut (13) guided on the adapter screw.
