1、屋面防水一般的施工工序
驗收找平層→清理基層→配制水泥粘合劑→做附加層→基層施工→保護層→養護。卷材鋪設粘結前,先將屋面防水卷材預鋪開(kāi),找正,然后將屋面防水卷材兩端對折卷起,把配制好的水泥粘合劑倒入基層上,并用刮板均勻的刮開(kāi),再將屋面防水卷材向前推鋪,并及時(shí)用刮板排除遺留在屋面防水卷材內部的空氣,刮出多余粘結劑。屋面防水卷材與找平層的粘結率≥85%。
Acceptance leveling layer → → formulated to clean the grassroots do an additional layer of cement binder → → → Base Construction protective layer → conservation. Before laying the adhesive sheet, the first pre-roll roofing membrane, alignment, and then fold the ends of the roof waterproofing membrane rolled, the preparation of a good cement adhesive poured onto the grass roots, and even with a scraper scratch, and then push forward roofing membrane shop, and promptly left on the roof with a scraper to exclude the air inside the waterproof membrane, scraped off the excess
adhesive. Bond rate roofing membrane and leveling layer ≥85%.
2、屋面防水接縫施工:隔汽層、防水層和附加層均采用搭接縫方法,用水泥粘合劑粘結,寬度為10cm。附加層接縫與防水層接縫錯開(kāi)5cm以上。屋面防水卷材搭接寬度長(cháng)邊8-10cm,短邊10-15cm,相鄰短邊接縫應錯開(kāi)100cm以上,墻面與地面夾角處均為30cm以上。
Seam roofing construction: vapor barrier, waterproof layer and the additional layer are made of lap joint approach with cement adhesive bonding, a width of 10cm. Additional layer seams and waterproof layer joints staggered more than 5cm. Roofing waterproofing membrane lap width of the long side 8-10cm, short side 10-15cm, adjacent short side seams should be staggered over 100cm,walls and floor are at an angle of more than 30cm.
3、卷材鋪粘完畢后,需在防水層上做1:2.5水泥砂漿厚度為2cm的保護層,分二次抹成,二層接茬必須錯開(kāi)20cm以上,保護層要求平整,并灑水養護。
After completion of sticky web shop, you need to do on a waterproof layer: 2.5 cement mortar protective layer thickness of 2cm, divided into secondary wipe, floor Jiecha must be staggered more than 20cm, the protective layer should be smooth and sprinkler maintenance.
4、使用無(wú)紡布降低防水層受結構運動(dòng)作用,加一條泡過(guò)柔韌型防水漿料的無(wú)紡布在裂縫處。

5、做水泥砂漿保護層,用水泥砂漿在干固后的防水層上涂刷做保護層。
