The color steel composite board has the advantages of convenient construction, high strength and beautiful appearance, so now it is often used in the roof of buildings. But in the actual use, it is found that there will be leakage problems, which has a lot to do with the details of its device. Generally speaking, the leakage of color steel composite plate roof is mainly caused by self tapping screw, color steel plate lap, roof tile, rivet, deformation caused by people on the roof and falling of waterproof glue on the decoration parts such as daylighting window. The corresponding leakage points can be divided into the following points
1. The roof screw and fastener are leaking. This phenomenon 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 or form a concave surface, resulting in roof drip leakage and accumulation of insulation cotton, the accumulation of a little makes a lot, forming a multi-point leakage. In addition, the position of the self tapping wire is not correct, the purlin under the color steel plate is missed, and the hole is directly formed, which is also one of the important reasons for water leakage. This kind of water leakage phenomenon may not be obvious in the roof structure of single-layer color steel plate without thermal insulation system. The main reason is that the rain water is directly lax and does not necessarily drip rapidly after passing through the parts touched by steel plate and purlin.
2. There is water leakage at the lap joint of color steel plate. If the tile wave is too low or the amount of rain 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. The roof tiles are leaking. In the construction of light steel structure roof, water leakage caused by roof ridge tile is also a common phenomenon. In the dry season, especially when the amount of rain is large, the splash of rain water passes through the gap between the two color steel composite plates at the lower part of the back tile, forming a large area of leakage.
In view of these leakage reasons, the roof screw and fastener, color steel composite plate lap joint and roof tile are treated with waterproof treatment. The construction process is as follows: finishing the bottom layer → brushing the bottom layer to treat the waterproof material → construction of additional reinforcement layer → brushing the waterproof coating.
Jinan color steel composite roof leakage, if not timely treatment and repair, then a long time may bring more things, but also reduce its service life, improve the use of capital. If you want to solve this problem fundamentally, you must pay attention to the details of each device during installation.
