COMPOSITE CONSTRUCTION ELEMENT, IN PARTICULAR FOR THE MANUFACTURE OF COVERING STRUCTURES OR WALL STRUCTURES OF BUILDINGS
A composite construction element (1, 101) is described which may be used in the manufacture of covering structures or wall structures of industrial warehouses, housing and buildings in general, comprising a body (2) made of expanded plastics material provided with opposite faces (2a, 2b) and a slab-shaped coating element (5, 105a, 105b) associated to at least one of the faces (2a, 2b) of the body (2). The slab-shaped coating element (5, 105a, 105b) comprises a plurality of substantially adjoining and substantially U-shaped adjacent sections (6) provided with respective means for mechanically clinching (11) the slab-shaped element (5, 105a, 105b) to the expanded plastics material. Advantageously, the slab-shaped element (5, 105a, 105b) is stably associated to the mass of expanded plastics material by means of the mechanical clinching means forming part of the slab-shaped element (5, 105a, 105b) itself.
