威尼斯人667801官网异型部位防水如何有效施工?

发布时间:2021-08-17 来源:/

随着建筑行业的发展,我国出现大量的彩钢板屋面结构的建筑;像大型的厂房或物流库房等屋面都是彩钢板构成的;然而在使用后,彩钢板屋面渗漏水现象较为普通,已引起关注和重视!那么彩钢板是如何做防水是个问题,如何做好防水更是个问题!普遍常见漏水部位都是彩钢板天沟、板缝、钉孔部位等异性部位;那么下面就由小编为大家简单梳理一下威尼斯人667801官网异型部位如何有用施工?

With the development of construction industry, there are a large number of buildings with color steel sheet roof structure in China; The roofs of large factories or logistics warehouses are made of color steel plates; However, after use, the phenomenon of water leakage of color steel sheet roof is relatively common, which has attracted attention and attention! So how to do waterproof of color steel plate is a problem, and how to do waterproof is even more a problem! The common water leakage parts are color steel plate gutter, plate seam, nail hole and other heterosexual parts; Now let's briefly comb out how to construct the special-shaped parts of color steel tile by Xiaobian?

雨水口、空调管线、天沟、墙体、风机根部等重 点渗水部位,要铺贴一层附加层,宽度为300mm;或根据实际需要,对重 点易渗水部位加贴附加层,檐口部位要进行包檐处理。重 点渗水部位的处理方法说明如下:

An additional layer with a width of 300mm shall be paved at key water seepage parts such as rainwater inlet, air conditioning pipeline, gutter, wall and fan root; Or according to the actual needs, additional layers shall be added to the key parts prone to water seepage, and the cornice shall be covered. The treatment methods of key water seepage parts are described as follows:

1、钉孔处

1. Nail hole

钉孔容易生锈,要用密封胶预先处理。

Nail holes are easy to rust and should be pretreated with sealant.

2、墙面与墙体交接部位

2. Junction of wall and wall

需在墙体上开凿5cmx10cm见方的槽,槽底部压光,防水层粘贴在上面后,用抗裂砂浆填实;或者直接在墙体上用金属压条固定防水层,然后用密封材料对卷材收口部位进行密封处理。

A 5cm × 10cm square groove shall be cut on the wall, the bottom of the groove shall be calendered, the waterproof layer shall be pasted on it, and then filled with anti crack mortar; Or directly fix the waterproof layer with metal strip on the wall, and then seal the closing part of the coiled material with sealing material.

3、屋面柱状体与屋面板交接部位

3. Junction of roof column and roof slab

此处是钢结构屋面比较容易渗水的部位之一,需在防水层的上方加焊金属挡水条或金属防水板,缓解来自钢柱上方的冲力;上方卷材部位要用缠绕法施工,使卷材不易脱落;挡水板上方用密封材料进行密封处理。

This is one of the parts where the steel structure roof is prone to water seepage. Metal water retaining strip or metal waterproof board shall be welded above the waterproof layer to alleviate the impulse from above the steel column; The upper coiled material shall be constructed by winding method to prevent the coiled material from falling off; The upper part of the water baffle is sealed with sealing material.

4、屋面天沟部位

4. Roof gutter

金属屋面天沟渗水情况比较普遍,主要原因为设计流水量不足。在突遇特大暴雨时,雨水量急剧增加却又无法排出,当雨水量积存高度超过房檐下方墙体高度时,雨水就会从房檐下方内溢。

The water seepage of metal roof gutter is common, and the main reason is the insufficient design water flow. When encountering a severe rainstorm, the amount of rainwater increases sharply but cannot be discharged. When the accumulated height of rainwater exceeds the height of the wall below the eaves, the rainwater will overflow from below the eaves.

解决这一难题的方法,主要有增加排水口和对天沟做防水处理两种方法。此处只对天沟防水处理法作一说明一步,沿天沟边沿处切除伸入天沟内的屋面板,然后用50cm宽的白铁皮对折,再压成一定角度,角度大约等于屋面板与天沟形成的夹角,把铁皮的一侧插入屋面板的下方,另一侧用铆钉固定在天沟壁上

There are two methods to solve this problem: increasing the drainage outlet and waterproof the gutter. Here, only the gutter waterproof treatment method is described. Cut the roof slab extending into the gutter along the edge of the gutter, then fold it in half with 50cm wide white iron sheet, and then press it into a certain angle. The angle is about equal to the included angle between the roof slab and the gutter. Insert one side of the iron sheet under the roof slab and fix the other side on the gutter wall with rivets
