A prefabricated composite structure for forming a pitched roof

摘要

A prefabricated composite structure (1) for forming a pitched roof comprises an outer support panel (2) and an underlying layer (3) of insulating material, and is suitable for fixing to a load-bearing structure of the roof juxtaposed similar prefabricated composite structures to form a first covering of the roof. The support panels (2) of the respective prefabricated composite structures of the covering are fitted together with overlapping portions and comprise at least one seat (14) extending in a direction substantially perpendicular to an eaves line of the roof in order to house projecting counter-battens (15) of the secondary frame, to which battens of the secondary frame of the roof, extending parallel to the eaves line and supporting discontinuous covering elements, are fixed in a manner such that the battens are kept spaced from the support panel (2) by a predetermined distance which is variable in dependence on design data, the architecture of the roof, and local hygrothermometric values. <IMAGE>
