Two-layered slab roof

摘要

The invention relates to a two-layered slab roof, in which the slabs (11) of the upper layer are supported by means of profiled rails (4) on the lower layer, the profiled rails comprising a partially open, cylindrical upper profiled part (6) and a partially open, cylindrical lower profiled part (5), of which the upper profiled part engages in the cylindrical hollow space of the cylindrical flanges (12) of two neighbouring upper slabs (11), whereas the lower profiled part (5) engages around cylindrical flanges (2) of two neighbouring lower slabs (1). Due to the resilient properties of the parts, a type of snap-fit locking thereby takes place between them. Lateral openings can be closed off by insulating blocks (7, 8) (Fig. 4). <IMAGE>
