我国南方地区,气候炎热多雨,时有冰雹。屋面的处理既要隔热又要防水。原来的做法是:在屋面基层上做刚性或柔性防水处理,防水面层砌地笼墙,安装600×600毫米的预制钢筋混凝土隔热平板。这种隔热板只起隔热作用,并不防水。我单位针对本地区的具体情况,经反复试制,生产出一种既防水又隔热的隔热板。板的构造见图1。这种隔
In southern China, the weather is hot and rainy with hail. Roofing should be insulated and waterproof. The original practice was to make a rigid or flexible waterproof treatment on the roof of the roof, waterproof the surface layer to cover the wall, and install a 600×600 mm prefabricated reinforced concrete heat insulation plate. This insulation board only provides insulation and is not waterproof. Based on the specific conditions in our region, our unit has repeatedly trial-produced and produced an insulation board that is both waterproof and heat-insulating. The structure of the board is shown in Figure 1. This compartment
