彩鋼屋面施工因素造成的漏水

①屋面螺釘和(he)緊固件出漏(lou)水。這(zhe)種(zhong)現象(xiang)較為(wei)多見，因為(wei)在施工過程當中(zhong)，攻(gong)(gong)絲(si)力(li)量過重(zhong)或(huo)(huo)過輕，自攻(gong)(gong)絲(si)打偏或(huo)(huo)打斜(xie)等都可能致使自攻(gong)(gong)絲(si)橡(xiang)膠墊處變形(xing)、脫落形(xing)成凹面，進而造成屋面點(dian)滴漏(lou)水并通過保(bao)溫(wen)棉聚積以形(xing)成點(dian)漏(lou)水。另(ling)外，自攻(gong)(gong)絲(si)位置不正，彩鋼板下(xia)的檁條而直(zhi)接形(xing)成孔洞也是漏(lou)水的原因之一。
②彩(cai)鋼(gang)板(ban)搭(da)接處漏(lou)水(shui)(shui)。兩張(zhang)板(ban)搭(da)接不(bu)緊或(huo)長度(du)不(bu)夠(gou)，以及自攻絲沒(mei)有打(da)滿形成(cheng)(cheng)空(kong)隙，造成(cheng)(cheng)橫向搭(da)接處漏(lou)水(shui)(shui)。彩(cai)鋼(gang)板(ban)瓦(wa)波過(guo)低或(huo)咬合不(bu)足三(san)百六十度(du)，雨水(shui)(shui)量(liang)大沒(mei)過(guo)瓦(wa)波的時(shi)候，容易造成(cheng)(cheng)大面(mian)積(ji)漏(lou)水(shui)(shui)，且使人不(bu)易發(fa)覺漏(lou)水(shui)(shui)點。若(ruo)坡度(du)小于百分之(zhi)五，板(ban)從脊到檐應連續，中間(jian)不(bu)應有搭(da)接。
③屋(wu)(wu)脊(ji)(ji)處(chu)波峰太高，屋(wu)(wu)脊(ji)(ji)蓋(gai)(gai)板(ban)無法；縱向搭接(jie)不(bu)放膠泥或(huo)硅膠，形(xing)成(cheng)縫隙而漏(lou)水(shui)；屋(wu)(wu)脊(ji)(ji)蓋(gai)(gai)板(ban)縱向搭接(jie)用鉚釘(ding)連接(jie)，熱脹冷縮強(qiang)度不(bu)夠而拉(la)斷鉚釘(ding)，形(xing)成(cheng)漏(lou)水(shui)；屋(wu)(wu)脊(ji)(ji)蓋(gai)(gai)板(ban)與(yu)屋(wu)(wu)面板(ban)之間不(bu)敷設(she)堵(du)頭(tou)，或(huo)堵(du)頭(tou)放置不(bu)規范而脫落形(xing)成(cheng)漏(lou)水(shui)。
④采(cai)(cai)光板(ban)(ban)部(bu)位是維護系統(tong)的重要部(bu)位，采(cai)(cai)光板(ban)(ban)安裝中(zhong)的膠泥鋪(pu)設、螺釘是屋(wu)(wu)面漏水(shui)(shui)的主要隱患；采(cai)(cai)光板(ban)(ban)板(ban)(ban)型(xing)與屋(wu)(wu)面板(ban)(ban)板(ban)(ban)型(xing)不吻合，采(cai)(cai)光板(ban)(ban)兩(liang)側波(bo)峰(feng)高于(yu)屋(wu)(wu)面板(ban)(ban)，安裝后，密封過嚴形成(cheng)采(cai)(cai)光板(ban)(ban)內(nei)外氣壓差，毛(mao)細水(shui)(shui)從采(cai)(cai)光板(ban)(ban)兩(liang)側縫(feng)隙(xi)進入屋(wu)(wu)面內(nei)部(bu)漏水(shui)(shui)；采(cai)(cai)光板(ban)(ban)縱向(xiang)搭接長度不夠，且(qie)膠泥老化失去粘性；縱向(xiang)膠泥脫落；采(cai)(cai)光板(ban)(ban)和(he)彩(cai)鋼板(ban)(ban)之間為剛性搭接，中(zhong)間的縫(feng)隙(xi)未密封。
⑤風機(ji)開孔未(wei)按設(she)(she)計(ji)節點進(jin)行(xing)處理(li)，鋼堵頭放(fang)置未(wei)敷設(she)(she)膠泥和(he)硅(gui)膠；風機(ji)開孔四(si)周(zhou)(zhou)預留范(fan)圍(wei)較小(xiao)，雨水流(liu)淌不(bu)暢，容易(yi)積水；開孔四(si)周(zhou)(zhou)包邊(bian)搭接未(wei)進(jin)行(xing)處理(li)；開孔內部四(si)周(zhou)(zhou)未(wei)加結構件(jian)，形成低凹積水；
⑥屋面外板安裝未(wei)加泡沫堵頭，屋面外板未(wei)下扳(ban)；墻面外板長度不足，且檐口部位未(wei)加收邊。
⑦由于鋼(gang)板天溝比較薄，焊縫(feng)容(rong)易出現(xian)問(wen)題，并(bing)且天溝不進行，使用一段時(shi)間后，腐蝕嚴重。
⑧對屋面圍(wei)護(hu)不注意保護(hu)，隨意踩踏屋面進而(er)破壞(huai)了屋面平整甚至出現裂紋。
⑨雨水管(guan)材用塑料(liao)管(guan)材，強度(du)差，鋼結(jie)構廠房(fang)從安裝到(dao)投產(chan)運行，容易受損。
