屋顶防水措施有哪些?

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

一、屋顶防水措施
1、 Roof waterproof measures
1、避免外来水的接触
1. Avoid contact with foreign water
雨雪水等自然水源在重力和外力的推动作用下,会缓慢渗入室内。为防止水源进入室内或者在建筑结构上逐渐渗入,一般会对屋面采取加强层处理,如防水卷材层或庇水板与翼板等结构设计,以便拉开水源与屋顶直接接触的可能性。
Rain, snow and other natural water sources will slowly penetrate into the room under the promotion of gravity and external forces. In order to prevent the water source from entering the room or gradually infiltrating into the building structure, the roof will generally be treated with reinforced layer, such as waterproof coiled material layer or structural design of water shelter plate and wing plate, so as to open the possibility of direct contact between the water source and the roof.
2、规划排水系统
2. Planning drainage system
水分滞留积累在某处,很容易造成水压加大而增加其入侵能力。在建筑物的表面渗入作用下,水分会不断渗入室内,造成室内天花板、墙面潮湿发霉、漏水等现象。防水施工的排水设计时需要让水分不滞留并有序地排出。
Water retention accumulates somewhere, which is easy to increase the water pressure and increase its invasion capacity. Under the infiltration of the surface of the building, water will continue to penetrate into the room, resulting in damp, moldy and water leakage of the indoor ceiling and wall. The drainage design of waterproof construction needs to ensure that the water does not stay and is discharged orderly.
3、防止使用水的渗漏
3. Prevent leakage of water
使用水包含生活用水、家电设备用水、生产用水和排放污水等。确保这些使用水源的管线及室内墙地面的防水层设计,能防止水源渗漏。防水层的设计仍针对各种水源的特性、使用围、使用方式及排水系统等,进行完善的防水规划。
The water used includes domestic water, household appliance water, production water, sewage discharge, etc. Ensure that these pipelines using water sources and the waterproof layer design of indoor wall and ground can prevent water leakage. The design of waterproof layer still carries out perfect waterproof planning according to the characteristics, use enclosure, use mode and drainage system of various water sources.
4、隔绝外来水的侵入
4. Isolate the invasion of foreign water
用以隔绝及防堵雨水、雪水、露水、地下水等外来水源的侵入及渗漏。绝太部份应用在房屋内外墙及屋顶的防水设计上。常见的方法如:防水填缝胶或衬垫条的防水处理、涂刷防水性能佳的涂膜防水材料、覆盖式屋顶的防水层设计等。
It is used to isolate and prevent the invasion and leakage of rainwater, snow, dew, groundwater and other external water sources. Most of them are used in the waterproof design of internal and external walls and roofs of houses. Common methods include: waterproof treatment of waterproof joint sealant or liner strip, coating waterproof material with good waterproof performance, waterproof layer design of covered roof, etc.
二、屋顶防水处理方法
2、 Roof waterproof treatment method
1、先做好基础的准备工作。
1. Make basic preparations first.
2、再将基层清理干净,确保施工前基层上面没有尘土和建筑杂物。
2. Then clean the base course to ensure that there is no dust and building debris on the base course before construction.
3、然后涂刷基层处理剂,如果使用高聚物改性沥青卷材施工的话,我们需要要按照规定使用,基层处理剂调配搅拌均匀后,用长滚刷涂抹在基层表面上,一般情况下4小时之后就可以铺贴卷材了。
3. Then brush the base course treatment agent. If the high polymer modified asphalt coiled material is used for construction, we need to use it according to the regulations. After the base course treatment agent is mixed evenly, apply it on the base course surface with a long roller brush. Generally, the coiled material can be paved after 4 hours.
4、附加层可以用改性沥青卷材热熔完成,对女儿墙、水落口、管根、阴阳角等地方做上附加层,注意附加层的面积要符合设计的规定。
4. The additional layer can be completed by hot melting of modified asphalt coiled material. Additional layers shall be made on parapet, water outlet, pipe root, internal and external corners, etc. note that the area of the additional layer shall meet the design requirements.
5、贴上卷材。撕开隔离膜,开始铺贴卷材,并适当裁剪边缝。
5. Attach the coil. Tear off the isolation film, start paving the coiled material, and cut the edge seam appropriately.
6、热熔封边,把卷材搭接的地方用热熔枪加热连起来。
6. Hot melt edge sealing: connect the lap joint of coiled materials with hot-melt gun.
7、做防水蓄水的实验。
7. Do waterproof and water storage experiments.
8、检查记录,这项工作通常是由质检人员进行验收,并记录在案。
8. Inspection records. This work is usually accepted by quality inspection personnel and recorded.
9、防水层的养护。使用隔离板或者砂浆做一层面层保护层。
9. Curing of waterproof layer. Make a layer of protective layer with isolation plate or mortar.
10、保护成品。施工后48小时,不能与水分接触或者踩踏。
10. Protect finished products. 48 hours after construction, it shall not be in contact with water or trampled.
