在炎热地区住宅屋面通常设500×500加筋混凝土隔热板,用120×120×120砖堆架空;由于是直接放在屋面防水层上,使屋面板增加了负重,要求屋面板承载能力加大。特别是上人屋面,砖堆下的卷材防水层也因局部受压而极易损坏。如果用与板下开间等跨的轻型槽板或预应力槽瓦作隔热板,直接在承重横墙的位置上砌高120的240墙架空。保温层处用加气混凝土砌块垫平,这样,受力明确,并减少了屋面板的荷载,保护了防水层。 500×500 reinforced concrete thermal insulation panels are usually installed on residential roofs in hot areas, with 120×120×120 bricks piled overhead. As the roof is placed directly on the roof waterproof layer, the roof panels are loaded, and the required load capacity of the roof panels is increased. Big. Especially on the roof of a person, the waterproof layer of the coil under the brick pile is also easily damaged due to local pressure. If the board is used as a heat insulation board with a light groove plate or prestressed slot tile, etc. between the board and the open space, it will be erected on the wall of the load-bearing cross wall with 240 walls of 120 high. The insulation layer is flattened with aerated concrete blocks, so that the stress is clear, and the roof panel load is reduced, protecting the waterproof layer.
