卷材平屋顶构造层次的常规做法如图1所示。从图1构造层次做法与屋面施工实际情况结合分析,屋面整体防雨水渗漏效果不尽合理,其不利因素如下:1.屋面结构层上常有各种类别管线交叉布置不规则现象,尤以电气照明施工常滞后于屋面结构层施工,而且后穿的塑料管又有胀力,易凸出于20毫米厚水泥砂浆找平层上表面,因此,一毡二油隔汽层因找平层不平而
The conventional practice of flat roof construction of coils is shown in Figure 1. From the analysis of the structural hierarchy of Figure 1 and the actual situation of roof construction, the overall effect of preventing rainwater leakage from the roof is not reasonable. The unfavorable factors are as follows: 1. There are often irregular layouts of cross-arrangement of pipelines in various types of roof structure. The construction of electric lighting often lags behind the construction of the structural layer of the roof, and the plastic pipe that is put through later has expansion force. It easily protrudes from the upper surface of the 20-mm-thick cement mortar screed. Therefore, the layer of felt and oil is not flat due to uneven screeding.
