彩鋼復合板屋面滲漏的原因?

來源:http://www.ebassfish.com/ 日期:2020-02-28 發布人:admin
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:
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. 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 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 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.
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。
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。
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.
