通过实际工程,对屋面细石混凝土防水保护层产生的纵横裂缝进行原因分析,指出刚性隔离层不能对柔性保温层及刚性防水保护层起到有效隔离作用,而采用柔性隔离层,能有效隔离从而减少屋面防水保护层裂缝的产生。通过比较,对于带有保温层的屋面防水保护层,采用柔性隔离层比砂浆等刚性隔离层更具优势。
Through the actual project, the reasons for the longitudinal and transverse cracks produced by the waterproofing protective layer of the fine stone concrete roof are analyzed. It is pointed out that the rigid insulating layer can not effectively insulate the flexible insulation layer and the rigid waterproof protective layer, and the flexible isolation layer can effectively isolate the rigid insulation layer Reduce the roof waterproof protective layer cracks. By comparison, for the roof with a thermal insulation layer of waterproof protective layer, the use of flexible insulation layer and mortar and other rigid isolation layer more advantages.
