Prefabricated concrete buildings with monolithic roof, wall, and floor members

摘要

Precast concrete wall panels and monolithic roof members may be fabricated separately and assembled on site to construct buildings of generally rectangular modular configurations having pitched roofs. The basic load bearing shell comprises opposed minimum area vertical concrete wall panels supporting a monolithic roof member comprising an integral deck/joist structure. The roof member includes a generally horizontal extending web portion disposed between opposed sloping web portions. Opposed upward cast projections on the eaves of the roof member form a recess for an insulating roof panel. The roof panels comprise expanded foam insulation sheets bonded to plywood decking for supporting conventional roofing material. The roof panels meet at a central ridge line and form with the horizontal web portion of the roof members a chase for electrical and mechanical components for the building. The wall panels are formed with opposed parallel flanges to form H or I beam cross sectional configurations to increase lateral stability and to provide for joining an interior wall to an outer wall formed by one of the wall panels.
