彩钢板屋面坡度一般较小，一般在6%以下。这种结构在我国中南部雨水较多地区较为常见，渗漏面积大，窗与屋脊结合处较轻。彩色钢板屋面在处理渗漏水时，有必要了解和分析其结构、渗漏点及原因。
一般来说，彩钢板屋面漏水主要是自攻螺丝、彩钢板搭接、屋脊瓦、抽芯铆钉、屋面彩钢板人为变形、采光窗等装饰部位防水胶脱落等造成的。相应的泄漏点可分为以下几点：一个。车顶螺钉和紧固件漏水这种现象主要发生在双层彩钢板和单层彩钢板屋面。施工过程中，自攻力过大、过轻，自攻螺钉歪斜等，可能造成自攻橡胶垫变形、脱落或形成凹面，导致屋面滴水渗漏，通过保温棉的堆积，越来越多的水积聚，形成多点漏水。另外，自攻线位置不正确，彩钢板下檩条直接漏水形成孔洞，也是漏水的重要原因之一。这种漏水现象在没有保温系统的单层彩钢板屋盖结构中可能不明显。主要原因是雨水渗漏后，钢板与檩条的接触部分直接分散，水不一定会迅速滴落。
2。彩钢板接头漏水
彩钢板横缝、竖缝、接头漏水。如果彩钢板的瓦波过低或雨水过大而无法通过瓦波，则容易形成大面积漏水，漏水点不易检测。一旦形成，就不容易修复，这在弧形屋顶中经常见到。主要原因是两块板搭接不紧，自攻丝未满而形成间隙。
三个。屋面砖漏水
在轻钢屋盖施工中，屋脊瓦渗漏也是常见现象。在雨季，特别是有大量雨水时，雨水的飞溅通过屋脊瓦下部两块彩钢板的接缝处，形成大面积渗漏。
在了解彩钢板屋盖结构、可能的漏水点及漏水原因后，对处理方案进行探讨。根据多年的施工经验，提出两种渗漏方案：
The slope of color steel sheet roof is generally small,generally below 6%. This kind of structure is common in the areaswith more rain in the south central part of China, with largeleakage area and light joint between window and roof ridge. It isnecessary to understand and analyze the structure, leakage pointand reason of the color steel sheet roof when dealing with theleakage water.
Generally speaking, the water leakage of color steel plate roofis mainly caused by the self tapping screw, color steel plate lapjoint, roof ridge tile, pop rivets, artificial deformation of colorsteel plate on the roof and the falling off of waterproof glue inthe decoration parts such as daylighting windows. The correspondingleakage points can be divided into the following points:
One. Water leaks in roof screws and fasteners
This phenomenon mainly occurs in the double-layer color steelplate and the single-layer color steel plate roof. In theconstruction process, the self tapping force is too large and toolight, and the self tapping screw is skewed, etc., which may causethe self tapping rubber pad to deform, fall off or form a concavesurface, resulting in water dripping and leakage on the roof, andthrough the accumulation of heat preservation cotton, more and morewater is accumulated, forming multi-point water leakage. Inaddition, the position of the self tapping wire is not correct, andthe purlin under the color steel plate leaks directly to formholes, which is also one of the important reasons for the waterleakage. This kind of water leakage may not be obvious in thesingle-layer color steel plate roof structure without heatpreservation system. The main reason is that after the rainwaterleakage, the contact part between the steel plate and the purlin isdirectly dispersed, and the water does not necessarily driprapidly.
2. Water leakage at color steel plate joint
The horizontal and vertical joints and joints of color steelplate are leaking. If the tile wave of color steel plate is too lowor the rainwater is too large to pass through the tile wave, it iseasy to form a large area of water leakage, and the water leakagepoint is not easy to detect. Once formed, it is not easy to repair,which is often seen in arc roofs. The main reason is that the twoplates are not tightly overlapped and the self tapping wire is notfull to form a gap.
Three. Water leakage of roof brick
In the construction of light steel roof, the leakage of ridgetile is also a common phenomenon. In the rainy season, especiallywhen there is a large amount of rain, the splashing of rain waterpasses through the joint of two color steel plates at the lowerpart of the roof ridge tile, forming a large area of leakage.
After understanding the structure of color steel sheet roof,possible water leakage points and the causes of water leakage, thetreatment scheme will be discussed. Based on years of constructionexperience, two leakage schemes are proposed:
