彩色钢瓦屋面易渗漏部位应进行系统的防水处理，主要有彩钢瓦的螺孔、彩钢瓦的搭接缝、彩钢瓦的屋面接缝、天沟檐口。

The parts of the colored steel tile roof that are prone to leakage should undergo systematic waterproofing treatment, mainly including the screw holes of the colored steel tile, the lap joints of the colored steel tile, the roof joints of the colored steel tile, and the eaves of the gutter.

彩钢板屋顶长期受到环境和气候的破坏。天气温差使彩钢瓦收缩变形。另外，强降雨使彩钢板屋顶长期摇晃。钉孔和接合处会长期磨损，导致胶垫损坏，导致严重漏水。

The color steel roof has been damaged by the environment and climate for a long time. The temperature difference in the weather causes the colored steel tiles to shrink and deform. In addition, heavy rainfall caused long-term shaking of the color steel roof. The nail holes and joints will wear for a long time, leading to damage to the rubber pad and serious water leakage.

有些房顶跨度大，人踩多会造成中间积水，中间重力增加。雨水越多，屋顶的变形越严重。一些房顶是用矿棉做的，可以起到吸水的作用。

Some roofs have a large span and more people stepping on them can cause water accumulation in the middle, resulting in an increase in gravity in the middle. The more rain, the more severe the deformation of the roof. Some roofs are made of mineral wool, which can absorb water.

下雨天，屋顶漏下的所有雨水都聚集在矿棉里，这会加重屋顶的重量，甚造成屋顶倒塌。有高有低，有高有低的屋顶漏水。防水施工用水泥抹八字角，防水保护用密封胶或防水涂料。胶合剂与金属不结合，容易产生裂缝，密封剂或涂料延伸率低，也会产生大裂缝。

On rainy days, all the rainwater leaked from the roof accumulates in mineral wool, which can increase the weight of the roof and even cause it to collapse. There are high and low roof leaks. Firstly, cement is used for waterproofing construction, and sealant or waterproof coating is used for waterproofing protection. Adhesives that do not combine with metals are prone to cracking, while sealants or coatings with low elongation can also cause large cracks.

比较容易处理和处理的是“防水天沟”。非专职人员很难发现本质的漏洞。因为天沟的设计尺寸和宽度不同，施工难度也不一样，有些太窄，所以需要剪掉彩板多余的檐口来包裹整个天沟。

The one that is relatively easy to handle and handle is the "waterproof gutter". Non dedicated personnel find it difficult to identify essential vulnerabilities. Due to the different design dimensions and widths of the gutter, the construction difficulty also varies, some of which are too narrow, so it is necessary to cut off the excess eaves of the color board to wrap the entire gutter.

排水沟漏水一般有两个方面。一是天沟设计不合理，淤泥堆积过多，排水不及时，残留的积水长期浸泡，造成天沟漏水。如果定期定期清理和冲洗天沟，天沟内就不会有过多的灰层，雨水也可以及时排出，不会被磨损。

There are generally two aspects to drainage ditch leakage. One reason is that the design of the gutter is unreasonable, with excessive accumulation of sludge, delayed drainage, and long-term soaking of residual water, resulting in gutter leakage. If the gutter is regularly cleaned and flushed, there will be no excessive ash layer inside the gutter, and rainwater can be discharged in a timely manner without being worn out.
