一般而言，彩钢板生产厂家彩钢板屋顶渗漏主要是由于自攻螺钉、彩钢重叠、屋脊瓦、抽心铆钉、屋顶上人造成彩钢变形、采光窗等装修部位防雨胶脱落等因素造成的。而且相应的渗漏点主要可分为以下几类：
Generally speaking, the leakage of color steel plate roof of color steel plate manufacturers is mainly caused by self tapping screws, color steel overlap, ridge tiles, pull out rivets, artificial color steel deformation on the roof, rain proof glue falling off at decoration parts such as daylighting windows and so on. Moreover, the corresponding leakage points can be divided into the following categories:
一、屋顶螺钉和紧固件漏水。
1、 Roof screws and fasteners are leaking.
这种现象主要发生在双层彩钢板和单层彩钢板屋顶上。在施工过程中，攻丝力过重、过轻、螺钉偏移、倾斜等。，可能会使自攻丝橡胶垫变形、脱落或形成凹面，形成屋顶点滴漏水，通过保温棉堆积，形成腋窝成毛，形成多点漏水。其他自攻丝位置不正确，错过彩钢板下的檩条直接形成孔洞也是漏水的重要原因之一。这种漏水现象在单层彩钢板没有保温系统的屋顶结构中可能不明显，主要是因为雨水在钢板与檩条接触的部位泄漏后会直接分散，不一定会快速滴落。
This phenomenon mainly occurs on double-layer color steel plate and single-layer color steel plate roofs. In the construction process, the tapping force is too heavy, too light, screw offset, inclination, etc., The self tapping rubber pad may deform, fall off or form a concave surface, resulting in drip water leakage on the roof. Through the accumulation of thermal insulation cotton, axillary hair formation and multi-point water leakage may be formed. Other self tapping positions are incorrect, and missing the purlin under the color steel plate to directly form holes is also one of the important reasons for water leakage. This kind of water leakage phenomenon may not be obvious in the roof structure without thermal insulation system of single-layer color steel plate, mainly because the rainwater will be directly dispersed after leakage at the contact part between the steel plate and purlin, and may not drip quickly.
二、彩钢板搭接处漏水。
2、 There is water leakage at the lap joint of color steel plate.
水平搭接缝和垂直搭接缝，彩钢板搭接处漏水，如果遇到彩钢板瓦波过低或雨量过大的情况，很容易形成大面积的漏水，而且不易发现漏水点，一旦形成不易维修，这种情况多见于弧形屋顶。其原因主要是两块板之间搭接不紧，自攻丝没有打满，形成空地等。
Horizontal lap joints, vertical lap joints and color steel plate lap joints leak. If the color steel plate tile wave is too low or the rainfall is too large, it is easy to form a large area of water leakage, and it is not easy to find the water leakage point. Once formed, it is difficult to maintain, which is mostly seen in arc roofs. The main reason is that the lap joint between the two plates is not tight, the self tapping wire is not full, forming an open space, etc.
三、屋脊瓦漏水。
3、 The ridge tiles are leaking.
轻钢结构屋面施工中，屋脊瓦引起的漏水也是比较常见的现象。干旱季节，特别是雨水量大时，雨水飞溅通过脊瓦下部两块彩钢板对接处的缝隙，形成大面积的漏水。
Water leakage caused by ridge tile is also a common phenomenon in the construction of light steel structure roof. In dry season, especially when there is a large amount of rain, the rain splashes through the gap between the two color steel plates at the lower part of the ridge tile, forming a large area of water leakage.
在了解彩钢板屋顶的结构、可能的泄漏点和泄漏原因后，让我们谈谈管理计划。结合多年的施工实践经验，提出了两种泄漏计划:
After understanding the structure, possible leakage points and causes of the color steel roof, let's talk about the management plan. Combined with many years of construction experience, two leakage plans are proposed:
1.屋顶整体重新做防水。该方案可使彩钢屋面形成一层完全连接的防水层，彩钢板生产厂家城工防水建议采用自粘卷材。自粘卷材是一种防水、密封材料，可与基面粘结，分为有胎自粘和无胎自粘两种。它由胎自粘、下自粘胶中心夹胎基组成，上覆为乙烯薄膜，下覆为可剥离的硅油薄膜。无胎自粘由自粘胶、上乙烯薄膜和下硅油薄膜组成。本品具有自愈性，即当卷材被穿刺或硬物嵌入时，会主动与这些物体结合，仍然能坚持出色的防水功能。
1. The whole roof shall be waterproof again. This scheme can make the color steel roof form a fully connected waterproof layer. The color steel plate manufacturer recommends using self-adhesive coiled material for urban waterproof. Self adhesive coiled material is a kind of waterproof and sealing material, which can be bonded with the base surface. It can be divided into tire self-adhesive and tire free self-adhesive. It is composed of tire self-adhesive and lower self-adhesive with tire base sandwiched in the center. It is covered with ethylene film on the top and strippable silicone oil film on the bottom. Tubeless self-adhesive consists of self-adhesive, upper ethylene film and lower silicone oil film. This product has self-healing, that is, when the coiled material is punctured or embedded by hard objects, it will actively combine with these objects, and still adhere to the excellent waterproof function.
2.对屋顶螺钉和紧固件、彩钢板搭接处和屋顶瓦进行防水处理。其施工流程为:清洁底层→涂底层处理防水材料→增强层施工→涂防水涂料。
2. Waterproof the roof screws and fasteners, color steel plate lap joints and roof tiles. The construction process is as follows: cleaning the bottom layer → coating the bottom layer with waterproof materials → construction of reinforcement layer → coating waterproof paint.
上述两种方案都可以有效地管理彩钢板屋顶渗漏情况，详细选择可以根据施工面积和其它原因来判断。
The above two schemes can effectively manage the leakage of color steel plate roof, and the detailed selection can be judged according to the construction area and other reasons.
