刚性防水屋面，由于构造简单，施工方便，防水可靠，技术容易掌握等特点，在广大地区，尤其是南方地区被普遍采用。但由于节点设计不合理，施工不精心，使用不当等因素，致使屋面渗漏现象还是普遍存在的。前一时期我们设计的经济房采用刚性屋面防水的较多，但出现的问题也较多 Rigid waterproof roofs, due to their simple structure, convenient construction, waterproof and reliable, and easy to grasp technology, are widely used in the vast areas, especially in the south. However, due to the unreasonable design of the nodes, poor construction, and improper use, the phenomenon of roof leakage still exists. In the previous period, we designed economic houses with more waterproof rigid roofs, but there were more problems.
