Laminated panel for roofs, ceilings and walls - with framework of longitunidal and transverse ribs

摘要

Laminated panel for roofs, ceilings and walls comprises a framework consisting of longitudinal and transverse ribs of reinforced concrete, on the lower surface of which is a fibrous concrete layer. Between the ribs are inserted lightweight filler bodies pref. of foamed polystyrene. On the upper surface of the frame is a perforated panel-of fibrous concrete, standard or lightweight concrete, or other lightweight building material with or without a vapour barrier pref. of bituminous felt. The panel is light, space-saving and cheap, and the degree of prefabrication is increased so much that remaining operations on site are confined to what is absolutely necessary.
