對別墅、農村住所、頂層裝修來說，屋面防水工程是一項重要工程，工程質量好壞關系到修建物的使用壽命，還會直接影響人民生產活動和生活的正常進行。下面長沙防水公司告訴大家(jia)屋面防水(shui)需要(yao)留(liu)意什么？

　　辦法/過程

　　1、技(ji)(ji)能準(zhun)備：屋面工(gong)(gong)(gong)程施(shi)工(gong)(gong)(gong)前，施(shi)工(gong)(gong)(gong)單位應安(an)排(pai)技(ji)(ji)能管理人員會審屋面工(gong)(gong)(gong)程圖紙(zhi)，掌握(wo)施(shi)工(gong)(gong)(gong)圖中的(de)細部結構及有關技(ji)(ji)能要求并依(yi)(yi)據工(gong)(gong)(gong)程的(de)實際情(qing)況(kuang)編制屋面工(gong)(gong)(gong)程的(de)施(shi)工(gong)(gong)(gong)計(ji)劃或技(ji)(ji)能措施(shi)。這樣(yang)防止(zhi)施(shi)工(gong)(gong)(gong)后留下(xia)缺陷，造成返工(gong)(gong)(gong)，同(tong)時工(gong)(gong)(gong)程依(yi)(yi)據施(shi)工(gong)(gong)(gong)安(an)排(pai)有計(ji)劃地打開施(shi)工(gong)(gong)(gong)，防止(zhi)工(gong)(gong)(gong)作遺失(shi)、紊亂(luan)、倒置(zhi)影(ying)響工(gong)(gong)(gong)程質量。

　　2、施(shi)(shi)工(gong)(gong)(gong)(gong)要求：屋面(mian)工(gong)(gong)(gong)(gong)程的防(fang)水必(bi)須(xu)由防(fang)水專(zhuan)業(ye)(ye)隊伍(wu)(wu)或(huo)防(fang)水工(gong)(gong)(gong)(gong)施(shi)(shi)工(gong)(gong)(gong)(gong)，嚴(yan)禁沒有資質等級證(zheng)書的單(dan)位(wei)(wei)和非(fei)防(fang)水專(zhuan)業(ye)(ye)隊伍(wu)(wu)或(huo)非(fei)防(fang)水工(gong)(gong)(gong)(gong)進(jin)行屋面(mian)工(gong)(gong)(gong)(gong)程的防(fang)水施(shi)(shi)工(gong)(gong)(gong)(gong)，建設單(dan)位(wei)(wei)或(huo)監理公司應(ying)認真地(di)檢查(cha)施(shi)(shi)工(gong)(gong)(gong)(gong)人員的上崗證(zheng)。施(shi)(shi)工(gong)(gong)(gong)(gong)中施(shi)(shi)工(gong)(gong)(gong)(gong)單(dan)位(wei)(wei)應(ying)按施(shi)(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序(xu)(xu)、層(ceng)次進(jin)行質量的自檢、自查(cha)、自糾并且做好(hao)施(shi)(shi)工(gong)(gong)(gong)(gong)記載，監理單(dan)位(wei)(wei)做好(hao)每(mei)步工(gong)(gong)(gong)(gong)序(xu)(xu)的檢驗工(gong)(gong)(gong)(gong)作，檢驗合格后方(fang)可(ke)進(jin)行下道工(gong)(gong)(gong)(gong)序(xu)(xu)、層(ceng)次的作業(ye)(ye)。

　　3、防(fang)(fang)水(shui)資料(liao)質量：屋面工(gong)程所采用的防(fang)(fang)水(shui)資料(liao)應(ying)有(you)資料(liao)質量證(zheng)明文件，并(bing)經(jing)指定質量檢(jian)(jian)(jian)測部門認證(zheng)，確(que)保(bao)其(qi)質量契合(he)(he)《屋面工(gong)程技能規(gui)范》（GB50207—94）或國家(jia)有(you)關標(biao)準的要求。防(fang)(fang)水(shui)資料(liao)進入施工(gong)現場后應(ying)附有(you)出廠檢(jian)(jian)(jian)驗(yan)(yan)(yan)報(bao)告單及出廠合(he)(he)格(ge)證(zheng)，并(bing)注明生產日期(qi)、批號、規(gui)格(ge)、名稱。施工(gong)單位應(ying)按規(gui)則取(qu)樣復(fu)檢(jian)(jian)(jian)，取(qu)樣復(fu)檢(jian)(jian)(jian)嚴格(ge)依(yi)照(zhao)見證(zheng)取(qu)樣送(song)樣準則，在建設單位代表或監理單位人(ren)員見證(zheng)下，由施工(gong)人(ren)員在現場抽(chou)樣，送(song)到實(shi)(shi)驗(yan)(yan)(yan)室進行實(shi)(shi)驗(yan)(yan)(yan)。經(jing)復(fu)檢(jian)(jian)(jian)合(he)(he)格(ge)，提(ti)交復(fu)檢(jian)(jian)(jian)實(shi)(shi)驗(yan)(yan)(yan)報(bao)告合(he)(he)格(ge)單后方(fang)可在防(fang)(fang)水(shui)工(gong)程中(zhong)應(ying)用。

　　4、環境要求：為了確保施工操作以及卷材鋪貼的質量，宜在+50C~+350C氣溫下施工；高聚物改性瀝青以及高分子防水卷材不(bu)宜(yi)在負(fu)(fu)溫以下施工，熱熔法鋪(pu)貼卷材(cai)能(neng)夠在-100C以上的氣(qi)溫條件(jian)下施工，這種卷材(cai)耐(nai)低(di)溫，在負(fu)(fu)溫下不(bu)易被(bei)凍壞(huai)。雨、雪、霜(shuang)、霧，或大氣(qi)濕(shi)度過大，以及大風天(tian)氣(qi)均不(bu)宜(yi)露天(tian)作業，否則應(ying)采取相(xiang)應(ying)的技能(neng)措施。

　　5、排水斜(xie)度(du)：平屋面的排水斜(xie)度(du)為2%~3%，當(dang)斜(xie)度(du)小(xiao)(xiao)于等于2%時，宜選(xuan)用資料找坡；當(dang)斜(xie)度(du)大于3%時，宜選(xuan)用結構找坡。天溝、檐溝的縱向(xiang)斜(xie)度(du)不應(ying)(ying)小(xiao)(xiao)于1%，溝底落差不得(de)超過200mm。水落口周(zhou)圍(wei)直徑(jing)500mm范圍(wei)內斜(xie)度(du)不應(ying)(ying)小(xiao)(xiao)于5%。
