At least partially above the prim. (5) beams (1) are insulating material (3) and a surface layer (4) of reciprocally joined plate parts above the insulating material. The plate parts are anchored relatively to the prim. beams by fixture elements, and possibly by sec. beams. On the ridge (8) of the roof structure is a longitudinal joist (10) which is rigidly fixed relatively to the prim. beams and to which the plate parts are stably fastened. |
