屋顶防水怎么做

 文章来源:http://www.jnldfs.com/ 发布时间:2022-01-21   

1、顶楼附加层施工
1. Construction of additional top floor
底层处理可使用热熔沥青类的防水卷材或高渗环氧树脂进行对漏水部位处理,对一些女墙、排水口、各类管道根部、阴阳角部分先做清洗再进行施工。
The bottom layer can be treated with hot-melt asphalt waterproof coiled material or high-permeability epoxy resin. Some women's walls, drains, roots of various pipes and internal and external corners can be cleaned before construction.
2、防水材料运输
2. Transportation of waterproof materials
由于屋顶面积较大,材料运输到楼顶也是一件困难的事,可使用各类滑轮、吊索等进行吊装进屋顶;使用人工就够呛了,使用吊车价格就昂贵;这样能节约不少时间。
Due to the large area of the roof, it is also difficult to transport materials to the roof. Various pulleys and slings can be used to hoist into the roof; The use of labor is enough, and the use of cranes is expensive; This can save a lot of time.
3、铺贴防水卷材
3. Paving waterproof coiled material
使用的卷材应符合相关的标准,将防水卷材裁剪成相应尺寸进行铺贴,建议铺贴多数裁剪多少,避免浪费;使用火焰枪对表层加热后进行铺贴,对卷材连接部位要注意热透,并趁卷材表层热透刚融化立刻进行黏贴。
The coiled material used shall comply with relevant standards. The waterproof coiled material shall be cut to corresponding size for paving. It is recommended that most paving materials be cut to avoid waste; After heating the surface layer with a flame gun, pave it. Pay attention to the heat penetration of the coiled material connection part, and stick it immediately when the coiled material surface layer is just melted.
4、卷材铺贴方法
4. Coiled material paving method
在铺贴时应从边上往中间方向施工或从地处往高处施工,接口应接顺水流的方向,让卷材以盖瓦片的状态叠起。
During paving, the construction shall be carried out from the edge to the middle or from the ground to the height. The interface shall be connected along the direction of water flow, and the coiled materials shall be stacked in the state of covering tiles.
5、热熔封边
5. Hot melt edge sealing
在铺贴完毕后还需对各个边缘进行二次封边,使用火焰枪对衔接处进行加热,直到能挤出沥青为止,按压冷却后完成,尾部还应使用密封胶进行封边。
After paving, it is necessary to seal each edge twice, heat the joint with a flame gun until asphalt can be extruded, press and cool it, and seal the edge with sealant at the tail.
6、刷防水涂料
6. Brush waterproof coating
卷材铺贴完工后,对表层进行清洁,在刷防水涂料前应确保干净、干燥;再进行涂刷防水材料,防水材料涂刷应无裂纹、气泡。防水材料干透后需进行二遍涂抹,此时一定需一道干透才能进行,如果未能干透防水效果将大打折扣。
After the completion of coiled material paving, the surface shall be cleaned, and it shall be clean and dry before applying waterproof coating; Then apply waterproof materials, which shall be free of cracks and bubbles. After the waterproof material is completely dry, it needs to be applied twice. At this time, it must be completely dry. If it is not completely dry, the waterproof effect will be greatly reduced.
7、铺保护层为防止防水层遭破坏
7. The protective layer shall be laid to prevent the waterproof layer from being damaged
在表层铺上一层保护层,其保护层应能全覆盖防水层;保护层应无裂纹、无气泡、无脱落等情况。
A protective layer shall be paved on the surface layer, which shall be able to fully cover the waterproof layer; The protective layer shall be free of cracks, bubbles and falling off.
