钢结构屋面防水堵漏怎么做？
How to do waterproof and leak stoppage for steel structure roofing?
由于目前我国钢结构建筑技术的还处于探索发展阶段及市场竞争的原因，经过对已建设完成的钢结构建筑进行的调查，钢结构建筑建成投入使用以后均存在不同程度的屋面漏水现象，屋面漏水已成钢结构建筑的质量通病。
Due to the current China's steel structure construction technology is still in the exploratory stage of development and the reasons of market competition, through the investigation of the steel structure construction has completed construction of steel structure building after put into use are different Water Leakage roof, roof Water Leakage has become the common quality defects of steel structure building.
一般来说，彩钢板屋面渗漏水主要是因自攻螺丝、彩钢板搭接、屋脊瓦、抽心铆钉、屋面上人引起彩钢板变形及采光窗等装饰部位防雨胶脱落等因素引起的。而与此对应的渗漏点则主要可以分为以下几点：
Generally speaking, the leakage of color steel plate roof is mainly caused by self tapping screws, color steel plate overlapping, roof tiles, core rivets, roof color plate deformation and lighting window and other parts of rainproof glue falling off and other factors. And the corresponding leakage point can be divided into the following points:
1、屋面螺钉和紧固件处漏水
1, roof screws and fasteners leakage
这种现象主要出现在双层彩钢板及单层彩钢板屋面，施工过程中，攻丝力量过重、过轻，自螺丝打偏、打斜等，都可能使自攻丝橡胶垫片变形、脱落或者形成凹面，造成屋 面点滴漏水并通过保温棉聚积，积少成多，形成多点漏水。另外，自攻丝位置不正，错过彩钢板下的檩条而直接形成孔洞也是引起漏水的重要原因之一。这种漏水现象在单层彩钢板不设保温系统的屋面 结构中可能不太明显，主要是因为雨水通过钢板与檩条接触的部位渗漏后直接分散，不一定迅速滴落。
This phenomenon occurred mainly in the double color plate and single color plate roof, construction process, tapping force overweight, underweight, self Dapian, ofoblique screw, self tapping rubber gasket may cause deformation, shedding or forming concave, and the Water Leakage drip caused roof insulation cotton accumulation, Many a little make a mickle. form multi-point Water Leakage. In addition, the self tapping position is not correct, Miss Choi Steel under the purlin directly to form one of the important reasons is caused by the hole Water Leakage. This phenomenon is Water Leakage roof insulation system in the single color plate in may not be obvious, mainly because of the rain through the plate and purlin contact parts leakage directly after the dispersion, not necessarily drop rapidly.
2、彩钢板搭接处漏水

水平搭接缝和竖向搭接缝，彩钢板家庄电动伸缩门 保定桌椅  保定水处理设备 河北机械加工  保定养老院  保定防水搭接处漏水，若遇见彩钢板瓦波过低或者雨水量大没过瓦波时，容易形成大面积漏水，且不易发觉漏水点，一旦形成不易检修，这种情况多见于 弧形屋面。其原因主要是两张板之间搭接不紧、自攻丝没有打满形成了空隙等等。
The level of joint and vertical joint, color steel plate joint Water Leakage, if meet wappo color steel plate is too low or the rain water before wappo, easy to form a large area of Water Leakage, and is not
ge, once the form is not easy to repair, this condition is common in arc roof. The main reason is that the overlap between the two plates is not tight, the self tapping wire is not full, forming voids and so on
