Claim:
A bar-type supporting framework comprising: a plurality of nodes having engagement elements, and a plurality of bars having engagement elements which hold the bars between the nodes in a form-fitting manner at least in a direction transverse to a longitudinal direction of each bar, wherein at least one of the following of at least one bar and at least two nodes connected by a bar are formed of a plurality of parts constructed so that at least one of the following conditions exist: the parts of at least one said bar formed of a plurality of parts, are form-fittingly held together by the engagement elements of the nodes when the engagement elements of the bar are rotated relative to the engagement elements of the nodes about an axis extending in the longitudinal direction of the bar, and the parts of said at least two nodes formed of a plurality of parts, are form-fittingly held together by the engagement elements of the at least one bar when the engagement elements of the at least one bar are rotated relative to the engagement elements of the nodes about said axis extending in the longitudinal direction of the at least one bar.
