ABSTRACT:
In order to render more economical ceiling latticeworks constituted by bars and joint-fittings, the pillars and joint-fittings 14 evince an identical cross-sectional contour with longitudinal flutings, for instance a contour in the shape of a cross. Thereby, the pillars can be substituted for the joint-fittings 14 in the pillars' connection zone. The chord bars 12 of the ceiling lattice are hollow, cross-sectionally rectangular sections and are connected by clamping locks each comprising two clamping jaws 19, engaging and being clamped in flutings 24 of the joint-fittings 14 or pillars.
