寿县合兴钢结构浅谈钢结构屋面形成漏水现象的原因发布时间：2015-12-5 9:57:09 浏览次数:688
1, the color of the steel plate overlap. Level lap seam and vertical lap seam, color steel plate joint leakage, if meet color steel plate wappo is too low or the rain water has never been wappo, easy to form large leakage and is not easy to find the leakage point, once the formation is not easy to repair. More common in curved roof. The main reason is that between two sheets of plate is not tight, no self tapping played form gap etc.
2, roof tile Water Leakage. In the light steel structure roofing construction, caused by roof tile Water Leakage is also a common phenomenon. In the rainy season, especially large amount of rain, the rain splash through the lower part of the ridge tile two color steel plate butt gap, forming large area leakage.
To prevent tile leaks, in construction should be used to increase the length of every parts of wappo tile flanging, cutting, gluing joint.
3, roofing screws and fasteners Department leakage. This phenomenon is more common, mainly appeared in double color steel plate and single color steel sheet roof. In the construction process, tapping power is overweight, light, since screws Dapian, beveling, may make self tapping rubber gasket distortion, loss or a concave, cause of roof drip leak and the heat insulation cotton accumulation, many a little makes a mickle, the formation of leakage. Also self tapping position, Miss Choi steel purlin directly to form holes is caused by leakage is one of the important reasons. The leakage phenomenon in single color plate not insulation roof structure of the system may not be obvious, mainly because of rainwater through the contact plate and purlin leakage location directly dispersed, not necessarily rapidly dropping.
