双层彩钢板和单层彩钢板的区别

一般来说，彩钢复合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、屋面上人引起变形及采光窗等装饰部位防雨胶脱落等因素引起的。
Generally speaking, the leakage of color steel composite plate roof is mainly caused by self tapping screws, color steel plate overlap, ridge tile, rivet rivet, roof deformation and window decoration and other decorative parts, such as rain proof glue fall off and other factors.
水平搭接缝和竖向搭接缝，彩钢复合板搭接处漏水，若遇见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, composite steel plate joint Water Leakage wappo met, if not too low or rain water vapor, easy to form a large area of Water Leakage, and is not easy to find Water Leakage, 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 is not filled with the gap, and so on.
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。

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.
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。
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.
在轻型钢结构屋面施工中，由屋脊瓦引起的漏水也是一种较为常见的现象。在雨季，尤其是雨水量大时，雨水的飞溅通过脊瓦下部两张彩钢复合板对接处缝隙，形成大面积渗漏。
In the light steel structure roofing construction, caused by roof tile Water Leakage is also a common phenomenon. In the rainy season, especially when large amount of rainwater, rainwater splashing through the lower tile two composite steel plate butt joint gap, the formation of large area leakage.
