A bar-type supporting framework having nodes (10, 12, 14) and bars (16, 18, 20) held between the nodes in a form-fitting manner at least in the direction transverse to the longitudinal direction of the bar by engagement elements (34), such that at least one bar (20) and/or at least two nodes (14) connected by a bar are formed of a plurality of parts (24, 26; 30, 32) that are form-fittingly held together by relative rotation of the engagement elements (34) of the bars and the nodes about an axis extending in the longitudinal direction of the bars.
