ABSTRACT:
A set of components for producing load-bearing scaffolds comprising profile bars and connecting bars each having an approximately .SIGMA.-shaped cross-section with a flat center web section. The connecting bars fit slidably in the profile bars to which they are attached by connecting means through perforations in each of the center web sections. The profile bars also have an inwardly angled free arm extending parallel to the center web section and having perforations to provide for connection of further components to the profile bars. Further components adapted for use with the above profile bars comprise fixing angles, packing pieces, cross-member brackets, reducing elements, bearing hole plates, angle elements and belt guide plates.
