屋(wu)面(mian)(mian)防(fang)(fang)(fang)水(shui)工(gong)程一般包括屋(wu)面(mian)(mian)卷材(cai)防(fang)(fang)(fang)水(shui),屋(wu)面(mian)(mian)涂膜防(fang)(fang)(fang)水(shui),屋(wu)面(mian)(mian)剛性防(fang)(fang)(fang)水(shui),瓦屋(wu)面(mian)(mian)防(fang)(fang)(fang)水(shui),屋(wu)面(mian)(mian)接縫密封防(fang)(fang)(fang)水(shui)。屋(wu)面(mian)(mian)防(fang)(fang)(fang)水(shui)嚴(yan)禁在雨天,雪天和(he)五級(ji)以上大風時施(shi)工(gong)。其施(shi)工(gong)的(de)環境氣溫條件要求與(yu)所使(shi)用的(de)防(fang)(fang)(fang)水(shui)材(cai)料(liao)及(ji)施(shi)工(gong)方法相適應。房屋(wu)建(jian)筑曾一度出現屋(wu)面(mian)(mian)滲漏率居高不下的(de)情況,嚴(yan)重(zhong)影響了房屋(wu)的(de)使(shi)用功能。已(yi)建(jian)房屋(wu)屋(wu)面(mian)(mian)發生滲漏水(shui)問題,直接影響到人們的(de)生活(huo)、工(gong)作和(he)學習。
要(yao)從根(gen)本上解決已建房(fang)屋(wu)(wu)屋(wu)(wu)面(mian)滲漏水(shui)問題(ti),就(jiu)要(yao)從防(fang)水(shui)工程(cheng)的設(she)計、施(shi)工、材料(liao)及管理(li)維護等(deng)方面(mian)著手,進行(xing)系統管理(li),綜合防(fang)治(zhi)。以提(ti)高防(fang)水(shui)工程(cheng)質量,杜絕滲漏為(wei)目標,從施(shi)工入手,嚴把材料(liao)質量關,提(ti)高設(she)計水(shui)平(ping)和加強管理(li),有針對性(xing)地采取具體措施(shi)進行(xing)綜合防(fang)治(zhi)。
屋面(mian)防(fang)水施工(gong)要注(zhu)意以下事項:
1.材料選(xuan)用
在屋面滲(shen)漏水(shui)治理工作中,應該大(da)力推廣應用新型防(fang)水(shui)材(cai)料(liao)(liao),應首先選用技術較先進、性能(neng)較優異(yi)的高聚(ju)物(wu)改性瀝青卷(juan)材(cai)及(ji)涂料(liao)(liao)、合成高分子卷(juan)材(cai)及(ji)涂料(liao)(liao)、彈(dan)塑性密(mi)封(feng)材(cai)料(liao)(liao)及(ji)新型剛性防(fang)水(shui)材(cai)料(liao)(liao)。
2.屋面防(fang)水設計
設(she)計時應(ying)根(gen)據建筑物性質、工程(cheng)特點、重(zhong)要程(cheng)度(du)和使用(yong)(yong)功能進行(xing)防(fang)(fang)水(shui)(shui)設(she)防(fang)(fang)。根(gen)據當地的(de)高(gao)和低氣溫、日溫差(cha)、屋面坡度(du)、防(fang)(fang)水(shui)(shui)層形式(外(wai)露或非外(wai)露)以及結構大小(xiao)等具體情況,選(xuan)用(yong)(yong)適宜的(de)防(fang)(fang)水(shui)(shui)材料,確定相應(ying)的(de)施(shi)工方案。
3.施工是關(guan)鍵
滲(shen)漏水(shui)治理工(gong)(gong)(gong)(gong)(gong)程(cheng)施(shi)工(gong)(gong)(gong)(gong)(gong)必(bi)須由經過專業技術培訓,熟悉施(shi)工(gong)(gong)(gong)(gong)(gong)規(gui)范(fan)和防(fang)水(shui)材(cai)料性能(neng)特點及(ji)適用范(fan)圍的訓練有素的專業防(fang)水(shui)施(shi)工(gong)(gong)(gong)(gong)(gong)隊伍進行(xing)施(shi)工(gong)(gong)(gong)(gong)(gong)。在施(shi)工(gong)(gong)(gong)(gong)(gong)過程(cheng)中必(bi)須嚴格遵守國家標(biao)準規(gui)范(fan),認(ren)真貫徹(che)執行(xing)工(gong)(gong)(gong)(gong)(gong)藝標(biao)準,一絲不茍(gou)、精心操(cao)作,這樣(yang)才能(neng)確保工(gong)(gong)(gong)(gong)(gong)程(cheng)質(zhi)量。
4.加(jia)強管理維護
定期進行(xing)屋(wu)面(mian)的(de)保(bao)養維(wei)護,如采取在每(mei)年雨季(ji)來(lai)臨前和入冬(dong)前對防水層(ceng)進行(xing)全(quan)面(mian)清掃檢查發(fa)現有(you)損壞之處及時(shi)修復等(deng)措施,對降低屋(wu)面(mian)滲漏(lou)率(lv),減(jian)少返修,節省開支(zhi),延(yan)長防水層(ceng)使用(yong)年限具(ju)有(you)十(shi)分重要的(de)意義。
