彩鋼板屋面坡度一般較小，一般在6%以下。這種結(jié)構(gòu)在我國中南部雨水較多地區(qū)較為常見，滲漏面積大，窗與屋脊結(jié)合處較輕。彩色鋼板屋面在處理滲漏水時，有必要了解和分析其結(jié)構(gòu)、滲漏點及原因。

一般來說，彩鋼板屋面漏水主要是自攻螺絲、彩鋼板搭接、屋脊瓦、抽芯鉚釘、屋面彩鋼板人為變形、采光窗等裝飾部位防水膠脫落等造成的。相應的泄漏點可分為以下幾點：一個。車頂螺釘和緊固件漏水這種現(xiàn)象主要發(fā)生在雙層彩鋼板和單層彩鋼板屋面。施工過程中，自攻力過大、過輕，自攻螺釘歪斜等，可能造成自攻橡膠墊變形、脫落或形成凹面，導致屋面滴水滲漏，通過保溫棉的堆積，越來越多的水積聚，形成多點漏水。另外，自攻線位置不正確，彩鋼板下檁條直接漏水形成孔洞，也是漏水的重要原因之一。這種漏水現(xiàn)象在沒有保溫系統(tǒng)的單層彩鋼板屋蓋結(jié)構(gòu)中可能不明顯。主要原因是雨水滲漏后，鋼板與檁條的接觸部分直接分散，水不一定會迅速滴落。

2。彩鋼板接頭漏水

彩鋼板橫縫、豎縫、接頭漏水。如果彩鋼板的瓦波過低或雨水過大而無法通過瓦波，則容易形成大面積漏水，漏水點不易檢測。一旦形成，就不容易修復，這在弧形屋頂中經(jīng)常見到。主要原因是兩塊板搭接不緊，自攻絲未滿而形成間隙。

三個。屋面磚漏水

在輕鋼屋蓋施工中，屋脊瓦滲漏也是常見現(xiàn)象。在雨季，特別是有大量雨水時，雨水的飛濺通過屋脊瓦下部兩塊彩鋼板的接縫處，形成大面積滲漏。

在了解彩鋼板屋蓋結(jié)構(gòu)、可能的漏水點及漏水原因后，對處理方案進行探討。根據(jù)多年的施工經(jīng)驗，提出兩種滲漏方案：

The slope of color steel sheet roof is generally small,generally below 6%. This kind of structure is common in the areaswith more rain in the south central part of China, with largeleakage area and light joint between window and roof ridge. It isnecessary to understand and analyze the structure, leakage pointand reason of the color steel sheet roof when dealing with theleakage water.

Generally speaking, the water leakage of color steel plate roofis mainly caused by the self tapping screw, color steel plate lapjoint, roof ridge tile, pop rivets, artificial deformation of colorsteel plate on the roof and the falling off of waterproof glue inthe decoration parts such as daylighting windows. The correspondingleakage points can be divided into the following points:

One. Water leaks in roof screws and fasteners

This phenomenon mainly occurs in the double-layer color steelplate and the single-layer color steel plate roof. In theconstruction process, the self tapping force is too large and toolight, and the self tapping screw is skewed, etc., which may causethe self tapping rubber pad to deform, fall off or form a concavesurface, resulting in water dripping and leakage on the roof, andthrough the accumulation of heat preservation cotton, more and morewater is accumulated, forming multi-point water leakage. Inaddition, the position of the self tapping wire is not correct, andthe purlin under the color steel plate leaks directly to formholes, which is also one of the important reasons for the waterleakage. This kind of water leakage may not be obvious in thesingle-layer color steel plate roof structure without heatpreservation system. The main reason is that after the rainwaterleakage, the contact part between the steel plate and the purlin isdirectly dispersed, and the water does not necessarily driprapidly.

2. Water leakage at color steel plate joint

The horizontal and vertical joints and joints of color steelplate are leaking. If the tile wave of color steel plate is too lowor the rainwater is too large to pass through the tile wave, it iseasy to form a large area of water leakage, and the water leakagepoint is not easy to detect. Once formed, it is not easy to repair,which is often seen in arc roofs. The main reason is that the twoplates are not tightly overlapped and the self tapping wire is notfull to form a gap.

Three. Water leakage of roof brick

In the construction of light steel roof, the leakage of ridgetile is also a common phenomenon. In the rainy season, especiallywhen there is a large amount of rain, the splashing of rain waterpasses through the joint of two color steel plates at the lowerpart of the roof ridge tile, forming a large area of leakage.

After understanding the structure of color steel sheet roof,possible water leakage points and the causes of water leakage, thetreatment scheme will be discussed. Based on years of constructionexperience, two leakage schemes are proposed:
