规范要求卷材应铺设在干燥的基层上。但在施工中,特别是在南方地区,要达到这个要求比较困难。在找平层中预留与大气连通的孔道,在施工与使用中又常常容易发生阻塞,反而会造成卷材层起鼓。因此,我单位在南方地区长期施工中,对卷材屋面湿贴法施工做了一些尝试和探索。实践证明,卷材屋面湿贴法施工不受基层干燥的限制,而且能保证工程质量,缩短工期。具体做法是:在预制结构屋面上,做水泥砂浆找平层,完后2～4 The specification requires that the web should be laid on a dry substrate. However, in the construction, especially in the southern region, it is difficult to meet this requirement. In the screed layer, the air channel that is connected with the atmosphere is reserved. In construction and use, blocking is often prone to occur, and the coiled material layer may cause drums. Therefore, in the long-term construction in the southern region, our company has made some attempts and explorations on the wet-coating construction of coiled roofs. Practice has proved that the construction method of wet roofing of coiled material is not limited by the drying of the base layer, but also can guarantee the quality of the project and shorten the construction period. The specific approach is: in the prefabricated structure roof, do the cement mortar leveling layer, after 2 to 4
