彩钢板屋面长期受到环境和气候的破坏。气候的温差导致彩钢瓦收缩变形。此外,大风大雨造成彩钢屋面长期振动。铁片的钉孔和接缝长期磨损会导致胶垫损坏,漏水严重。下面济南彩钢板厂来讲讲彩钢板的檐口破损的原因
The color steel plate roof has been damaged by the environment and climate for a long time. The temperature difference of climate leads to the shrinkage and deformation of color steel tiles. In addition, strong wind and heavy rain cause long-term vibration of color steel roof. Long term wear of nail holes and joints of iron sheets will lead to damage of rubber pads and serious water leakage. Next, Jinan Color Steel Plate Factory will talk about the cause of the damaged cornice of color steel plate
有的屋顶跨度大,人踩久了中间会积水,中间重力会增加。雨越大,屋顶变形越严重。有些屋顶是矿棉做的,可以吸水。
Some roofs have large spans, and water will accumulate in the middle after people step on them for a long time, and the middle gravity will increase. The more rain, the more serious the roof deformation. Some roofs are made of mineral wool, which can absorb water.
下雨天,屋顶漏下来的雨水都会聚集在矿棉里,加重重量,甚至导致屋顶坍塌。屋顶拐角处的女儿墙忽高忽低。初期防水施工,用水泥抹八字角,用密封胶或防水涂料做防水保护。水泥如果不与金属粘结,容易产生裂缝,如果密封胶或涂料伸长量小,也会产生大裂缝。
In rainy days, the rainwater leaked from the roof will gather in the mineral wool, which will increase the weight and even cause the roof to collapse. The parapet at the corner of the roof rises and falls. For initial waterproof construction, cement shall be used to plaster splayed corners, and sealant or waterproof coating shall be used for waterproof protection. If the cement does not bond with the metal, cracks are likely to occur. If the elongation of sealant or paint is small, large cracks will also occur.
更容易也更难处理的是“天沟防水”。非专门的人士很难找到本质的泄漏点。因为天沟的设计尺寸和宽度不一样,施工难度也不一样,有的太窄,需要把彩钢板多余的檐口剪掉才能把整个天沟包起来。
What is easier and more difficult to deal with is "gutter waterproofing". It is difficult for non specialized people to find the essential leakage point. Because the design size and width of the gutter are different, the construction difficulty is also different, and some are too narrow, so you need to cut off the redundant cornice of the color steel plate to wrap the entire gutter.
通常有两个方面的漏电流。一是天沟设计不合理,淤泥堆积太厚,排水不及时,残留积水长时间浸泡,导致天沟漏水。只要每年定期对天沟进行清理和冲洗,天沟就不会有过多的积灰,雨水也能及时排出,就不会磨损。
There are usually two aspects of leakage current. First, the gutter design is unreasonable, the sludge accumulation is too thick, the drainage is not timely, and the residual water is soaked for a long time, leading to the gutter leakage. As long as the gutter is cleaned and flushed regularly every year, there will be no excessive ash accumulation in the gutter, and rainwater can be drained in time, so that it will not be worn.
