彩钢复合板为什么会发生渗漏现象?

来源:http://www.jnjgcg.com/ 日期:2020-09-18 发布人:jiangucaigang
彩钢复合板具有施工便利、强度高、外形美观,因而现在常被用于建筑物的屋面。但是在实际运用中发现会发作渗漏的问题,这跟它的装置细节是有很大关系的。一般来说,彩钢复合板屋面渗漏水首要是因自攻螺丝、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修部位防雨胶掉落等要素引起的。而与此对应的渗漏点则首要能够分为以下几点:
Color steel composite board has the advantages of convenient construction, high strength and beautiful appearance, so it is often used in the roof of buildings. But in practice, leakage is found, which has a lot to do with the details of the device. Generally speaking, the leakage of color steel composite plate roof is mainly caused by self tapping screw, color steel plate lap joint, roof ridge tile, pop rivets, deformation caused by people on the roof, rain proof glue falling from decoration parts such as daylighting windows, etc. The corresponding leakage points can be divided into the following points:
1.屋面螺钉和紧固件处漏水。这种现象首要出现在双层彩钢板及单层彩钢板屋面,施工过程中,攻丝力气过重、过轻,自螺丝打偏、打斜等,都或许使自攻丝橡胶垫片变形、掉落或者构成凹面,造成屋面点滴漏水并经过保温棉聚积,积少成多,构成多点漏水。别的,自攻丝位置不正,错失彩钢板下的檩条而直接构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或许不太显着,首要是因为雨水经过钢板与檩条触摸的部位渗漏后直接涣散,不必定迅速滴落。
1. Water leakage at roof screws and fasteners. This phenomenon mainly occurs in the double-layer color steel plate and the single-layer color steel plate roof. During the construction process, the tapping force is too heavy and light, and the self screw is biased and skewed, etc., which may cause the self tapping rubber gasket to deform, fall or form a concave surface, resulting in the water leakage of the roof and the accumulation of heat preservation cotton, resulting in more water leakage. In addition, the position of 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 may not be very significant in the roof structure of single-layer color steel plate without thermal insulation system. The main reason is that the rainwater leaks directly through the parts touched by steel plate and purlin, and does not necessarily drip rapidly.

2.彩钢板搭接处漏水。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,容易构成大面积漏水,且不易发觉漏水点,一旦构成不易检修,这种情况多见于弧形屋面。其原因首要是两张板之间搭接不紧、自攻丝没有打满构成了空隙等等。
2. There is water leakage at the overlap of color steel plate. The horizontal and vertical lap joints and the lap joints of color steel composite plates are prone to water leakage. If the tile wave 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 detect the water leakage point. Once it is hard to maintain, this situation is more common in the arc roof. The main reason is that the lap between the two plates is not tight, and the self tapping wire is not filled to form a gap, etc.
3、屋脊瓦漏水。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。在旱季,尤其是雨水量大时,雨水的飞溅经过脊瓦下部两张彩钢复合板对接处缝隙,构成大面积渗漏。
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 there is a large amount of rain, the splash of rain water passes through the joint of two color steel composite plates at the lower part of the ridge tile, forming a large area of leakage.
针对这几个渗漏的原因,对屋面螺钉和紧固件处、彩钢复合板搭接处及屋脊瓦处进行防水处理。其施工流程为:整理底层→涂刷底层处理防水材料→附加增强层的施工→涂刷防水涂料。
According to the reasons of these leakage, waterproof treatment is carried out at the joints of roof screws and fasteners, color steel composite plates and roof ridge tiles. The construction process is: finishing the bottom layer → painting the bottom layer to treat the waterproof material → construction of additional reinforcement layer → painting the waterproof coating.
彩钢复合板屋面发生渗漏的情况假如不及时处理和修理,那么时间长了或许就会带来更多的事,还会减少它的运用寿命,提高运用本钱。想要从根本上解决这个问题,那么在安装时就必定要注意各个装置细节。
If the leakage of color steel composite board roof is not handled and repaired in time, it may bring more things if the time is long, reduce its service life and increase its cost. If you want to solve this problem fundamentally, you must pay attention to the details of each device during installation.
