Abstract (en)
The roofing system consists of horizontal prefabricated concrete members (3) which are subject to flexure, and curved members (4) with a compressed section. The horizontal members are in the form of hollow beams of triangular cross-section, closed at the ends and incorporating thermal insulation material (18). The curved members (4), made from fibrocement or metal with or without insulation have arc-shaped sections with edges at a tangent to the inclined sides (16) of the beams; they are designed to press against the edges of the beams, which absorb transmitted horizontal movements. A variant has a double-pent structure with vertical lights.
