卷材防水屋面施工中,檐口外侧和墙面常因预防措施不当而被沥青污染,影响建筑物的外观。怎样防止这类问题发生呢?现提出以下一些措施。1.对于有组织的排水屋面,施工前可先用废旧报纸、水泥袋纸塞紧出水口,以防沥青胶流出污染墙面,待屋面施工完毕取出。2.对于无组织的排水屋面,当浇热沥青胶至距边缘30～50厘米时,停止浇铺,改用10厘米宽漆刷边刷边铺。至檐口时,随时刮去赶压出来的胶料,以防流坠。
In the construction of coiled waterproof roofs, the outer side of the cornice and the wall are often contaminated by asphalt due to improper preventive measures, affecting the appearance of the building. How to prevent such problems from happening? Now we propose the following measures. 1. For organized drainage roofs, before construction, old newspapers and cement bags can be used to plug the outlets to prevent the asphalt glue from flowing out of the wall. After the roof construction is completed, it can be removed. 2. For unstructured drainage roof, when the hot asphalt glue is 30 to 50 centimeters away from the edge, stop pouring and use a 10 centimeter wide paint brush to brush the edge shop. When it is time to gargle, it is always necessary to scrape off the rubber that was pressed out to prevent falling.
