濟南彩鋼復合板屋面滲漏的原因

來源:http://www.ebassfish.com/ 日期:2021-05-21 發布人:jiangucaigang
彩鋼復合板具有施工便利、強度高、外形美觀,因而現在常被用于建筑物的屋面。但是在實際運用中發現會發作滲漏的問題,這跟它的裝置細節是有很大關系的。一般來說,彩鋼復合板屋面滲漏水首要是因自攻螺絲、彩鋼板搭接、屋脊瓦、抽心鉚釘、屋面上人引起變形及采光窗等裝修部位防雨膠掉落等要素引起的。而與此對應的滲漏點則首要能夠分為以下幾點:
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.屋面螺釘和緊固件處漏水。這種現象首要出現在雙層彩鋼板及單層彩鋼板屋面,施工過程中,攻絲力氣過重、過輕,自螺絲打偏、打斜等,都或許使自攻絲橡膠墊片變形、掉落或者構成凹面,造成屋面點滴漏水并經過保溫棉聚積,積少成多,構成多點漏水。別的,自攻絲位置不正,錯失彩鋼板下的檁條而直接構成孔洞也是引起漏水的重要原因之一。這種漏水現象在單層彩鋼板不設保溫系統的屋面結構中或許不太顯著,首要是因為雨水經過鋼板與檁條觸摸的部位滲漏后直接渙散,不必定迅速滴落。
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.彩鋼板搭接處漏水。水平搭接縫和豎向搭接縫,彩鋼復合板搭接處漏水,若遇見瓦波過低或者雨水量大沒過瓦波時,容易構成大面積漏水,且不易發覺漏水點,一旦構成不易檢修,這種情況多見于弧形屋面。其原因首要是兩張板之間搭接不緊、自攻絲沒有打滿構成了空隙等等。
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、屋脊瓦漏水。在輕型鋼結構屋面施工中,由屋脊瓦引起的漏水也是一種較為常見的現象。在旱季,尤其是雨水量大時,雨水的飛濺經過脊瓦下部兩張彩鋼復合板對接處縫隙,構成大面積滲漏。
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 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.
針對這幾個滲漏的原因,對屋面螺釘和緊固件處、彩鋼復合板搭接處及屋脊瓦處進行防水處理。其施工流程為:整理底層→涂刷底層處理防水材料→附加增強層的施工→涂刷防水涂料。
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.
濟南彩鋼復合板屋面發生滲漏的情況假如不及時處理和修理,那么時間長了或許就會帶來更多的事,還會減少它的運用壽命,提高運用本錢。想要從根本上解決這個問題,那么在安裝時就必定要注意各個裝置細節。
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.
