你的彩钢板屋面还在漏雨吗?试试这种方法!

1车顶螺钉和紧固件漏水
彩钢板这种现象主要发生在双层彩钢板和单层彩钢板屋面。在施工过程中,自攻力过大、过轻、自攻螺钉偏位、歪斜等,可能使自攻胶垫变形、脱落或形成凹面,造成屋面滴水渗漏,彩钢板并通过保温棉积聚,积存量大,形成多点漏水。另外,自攻丝位置不对,彩钢板下缺檩条而直接形成孔洞也是漏水的重要原因之一。这种渗漏现象在没有保温系统的单层彩钢板屋面结构中可能并不明显,主要原因是雨水直接通过钢板与檩条的接触部位扩散,不一定会迅速下降。

2 彩钢板搭接处渗漏
如果彩钢板的瓦波过低或降雨量过大,容易形成大面积漏水,不易找到漏点。一旦形成,就不易修复,这种情况在弧形顶板中比较常见。主要原因是两板重叠不紧、自攻丝不饱满、形成缝隙等。
三。屋面砖漏水
彩钢板轻钢结构屋面施工中,屋脊瓦漏水也是一种常见现象。在雨季,特别是雨水量大的时候,雨水会从屋脊瓦下部两块彩钢板的缝隙中飞溅出来,形成大面积的渗漏。

1. Water leakage at roof screws and fasteners

henomenon mainly occurs in the double-layer color steel plate and single-layer color steel plate roof. In the construction process, the tapping force is too heavy, too light, self screw deviation, skew, etc., which may make the self tapping rubber gasket deformation, fall off or form a concave surface, causing the roof drip water leakage, and accumulating through the insulation cotton, the accumulation makes a lot, forming multi-point water leakage. In addition, the position of the self tapping wire is not right, missing the purlin under the color steel plate and directly forming holes is also one of the important reasons for water leakage. This kind of leakage phenomenon may not be obvious in the roof structure of single-layer color steel plate without thermal insulation system, mainly because the rain water directly disperses through the contact part of steel plate and purlin, and does not necessarily drop rapidly.
2. Leakage at the lap joint of color steel plate
If the tile wave of the color steel plate 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 leakage point. Once it is formed, it is not easy to repair, this situation is more common in the arc roof. The main reason is that the overlap between the two plates is not tight, the self tapping wire is not full, forming a gap and so on.
3. Roof tile leaking
In the construction of light steel structure roof, water leakage caused by roof ridge tile is also a common phenomenon. In the rainy season, especially when the amount of rain is large, 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 leakage.
