屋面渗漏是房屋建筑工程中的质量通病,尤其屋面房屋渗漏更为严重。我县近几年建造的房屋大部份都是平屋面,其防水构造是在多孔板上做通混凝土刚性防水层,其上设置400×400×30的混凝土架空隔热板。由于屋面直接受到太阳光的幅射,屋面热传导对防水层的影响很大,尽管设置了混凝土架空隔热板,但根据几年来的使用情况看,这种防水形式一般使用2～3年,有的甚至1年。究其原因,由于屋面所受到的温度变化比其它建筑构件和
Roof leakage is a common problem in the quality of building construction, and in particular, roof leakage is even more serious. Most of the houses built in our county in recent years are flat roofs. The waterproof structure is made of perforated concrete rigid waterproof layer, and a 400×400×30 concrete overhead insulated panel is installed on it. As the roof is directly irradiated by sunlight, the heat conduction of the roof has a great influence on the waterproof layer. Although the concrete overhead insulation board is installed, according to the use situation in recent years, this type of waterproof is generally used for 2 to 3 years. Even 1 year. The reason for this is that due to the change in temperature of the roof over other building components and
