In the grooves (3,3') support blocks (2,2') are fixed in arbitrary number and positions of the under-construction (1), on which facade plates are formed with lateral C-shaped edge formations. In the rear edge formations rectangular stamped-out apertures are located, which make possible the suspension of the facade plates in the support blocks. On the leg feet ribs facing the profile axis are arranged. Behind these ribs, in connection with the intermediate rib (10) grooves are formed, in which profiles (8) can be inserted. The under-construction is backwardly open with a U-construction, the rear leg being provided with teeth (6,6'). The teeth (6a,6a') of the fixture angle (5,5') are in positive engagement with the rear leg teeth. Grooves (4,4') are integrated in the toothed leg.
