<p>A ceiling sheathing slab of reinforced concrete, concrete roof cover, and heat-insulating layer, are incorporated in a flat roof. The insulating layer (4) is located between the slab (6) and roof cover (3). The slab is borne by the load bearing walls (8). In the area of these walls, the cover is supported on the slab via sliding bearings (5) passing through the insulating layer. Slab and cover may be interconnected by hinge-jointed anchors (13). The slab can be firmly joined to the walls. The cover can bear a buffer layer (2) on the centre part bounded by a facia.</p> |
