彩钢板搭接处漏水
2, color steel plate lap leakage
水平搭接缝和竖向搭接缝,彩钢板搭接处漏水,若遇见彩钢板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, color steel plate joint
Water Leakage, if meet wappo color steel plate is too low or the rain
water before wappo, 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 wire is
not full, forming voids and so on.
3、屋脊瓦漏水
3, roof tile leakage
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 color steel plate butt joint gap, the formation of
large area leakage.
在了解了彩钢板屋面的结构、可能的渗漏点及漏水原因之后,我们再来谈谈治理方案。结合多年的施工实践经验,提出两种渗漏水方案:
After understanding the structure, the possible leakage point and
the leakage reason of color steel plate roofing, we will talk about the
treatment plan again. Combined with years of practical experience in
construction, two leakage schemes are put forward:
1、屋面整体重新做防水
1, the roof as a whole to re waterproof
此方案可使彩钢板屋面形成一层整体连接的防水层,城工防水推荐使用自粘卷材。自粘卷材是一种自身能与基面粘结的防水、密封材料,分为有胎自粘和无胎自粘两种。有胎自粘上、下自粘胶中间夹胎基组成,上覆面为乙烯膜、下覆面为可剥起的硅油膜。无胎自粘由自粘胶、上乙烯膜和下硅油膜组合而成。该产品有自愈性,即卷材在遭遇穿刺或硬物嵌入时,会自动与这些物体合为一体,仍能保持良好的防水性能。且上表皮有纯金属铝箔的材料,有抗热隔热作用。使得彩钢瓦在夏季时候温度可以降低5-10度。
This scheme can make the color steel roof form an integral
waterproof layer, and recommend self adhered coiled material for urban
waterproofing. Self adhered membrane is a kind of waterproof and sealing
material which can be bonded to the base surface. It is divided into
two types: self adhered and non self adhered. A tire, self-adhesive self
adhesive sandwiched between the base, the upper cladding is made of
vinyl film, the lower cladding is made of silicone film can be stripped
from the. The non tire self adhesion is made up of self viscose, upper
ethylene film and lower silicone oil film. The product is self healing,
that is, the coiled material will be automatically integrated with these
objects in the case of puncture or hard material embedding, and it can
still maintain good waterproof performance. And the upper epidermis has
pure aluminum foil material, which has thermal insulation effect. So
that the color steel tile in summer temperature can be reduced by 5-10
degrees.
2. Waterproof treatment of roof screws and fasteners, overlap of
color steel plate and roof tile. The construction process is as follows:
cleaning the base layer, brushing the base, treating waterproof
material, adding additional reinforcement layer and brushing waterproof
coating.
以上两种方案均能有效的治理彩钢板屋面渗漏水的情况,具体选择可根据施工面积及其他因素来判断。
The above two schemes can effectively control the leakage of color
steel roof roof, and the specific selection can be judged according to
the construction area and other factors
