<p>The assembly equipment is for prefab. partitions used to form the walls of prefab. buildings. These partitions have a frame at the edges and if necessary at the centre, and internal and external cladding panels, with insulating material between them if necessary. At different levels along the edge of one partition are U-shaped bridge-pieces each fixed at the ends to the edge. The arch of the bridge-piece passes through the edge of a second partition for fixing to the first, and a wedge is driven into the arch, so as to bear against the inside of the edge of this second partition.</p> |
