1.清理基層:表面應平整、干凈、干燥,細部構造應達到設計要求,如有缺陷應進行處理,合格后方可進行防水施工。
1 clean up the grassroots: The surface should be smooth, clean, dry, detailed structure should meet the design requirements, if any defects should be treated, waterproof construction can be carried out after passing.
2.涂刷基層處理劑:自粘防水卷材基層處理劑開桶后應充分攪拌,用滾刷均勻的涂刷于基層(參考用量為0.2kg/m2)。待基層處理劑完全干燥后鋪貼自粘防水卷材。
2 brushing primary treatment agent: self-adhesive waterproof membrane primary treatment agent should stir after opening bucket with brush evenly brushing the grass roots (refer to the amount of 0.2kg / m2). After primary treatment agent to be completely self-adhesive waterproof membrane dry paving.
3.節點處理:管根部位如雨水管、穿檣管等%考試大%部位的管根需先做密封處理后,再鋪貼附加層;轉角部位如陰陽角、平立面轉角鋪貼附加層;伸縮縫、施工縫等部位鋪貼附加層。附加層的水平面和垂直面寬度均應≥250mm.
3 node processing: Tube root parts of rain water pipes, tubes, etc.% mast wear test test large parts of the tube% sealed root need to do first, and then an additional layer of paving; corner site, such as yin and yang angle, flat facade Corner Stones additional layers; expansion joints, construction joints and other parts of the additional layer of paving. Horizontal and vertical width of the additional layer should ≥250mm.
4.鋪EVA防水卷材:先確定卷材鋪貼順序和方向,并在基層彈線,然后鋪貼卷材。鋪貼自粘防水卷材時,先揭下隔離紙,將有粘性的一面沿基準線鋪貼,隨揭隔離紙(膜)隨即滾壓卷材的表面并擠壓出空氣,以確保初始粘結強度。卷材縱向搭接縫要順直,搭接縫寬度30 ~50 mm,用滾筒用力壓實,確保防水卷材之間粘接牢固。
4 Shop EVA waterproofing membrane: Stones roll to determine the order and orientation, and at the grassroots level playing cord and Stones roll. Stones self-adhesive waterproof membrane, the first release paper peeled off the adhesive side paving along the baseline, then rolling over to expose the surface membrane separator paper (film) and squeeze out the air, in order to ensure that the initial sticking knot strength. Coil longitudinal lap seam to straight, lap seam width 30 ~ 50 mm, with a roller compaction force to ensure a solid bond between the waterproofing membrane.
5.卷材搭接與卷材收頭處理:卷材采用搭接方式,通過卷材高分子層搭接焊接,將兩幅卷材搭接在一起。無論是水平收頭,還是垂直收頭,應對收頭邊處采用配套密封膠密封,卷材在立面收頭時,應用金屬壓條固定,再用配套密封膠將金屬壓條上口和固定螺釘密封。
5 sheet lap and closed head coil treatment: membrane using an overlap, lap welding polymer layer through the coil, the two coils lap together. Whether it is the level of income head, or vertical closed head, closed head side to deal with ancillary office uses sealant, roll the head when closed facade, the application of metal layering fixed, and then supporting sealant bead catchy metal seal and fixing screws .
6.質量驗收:防水層驗收合格,進行下一道施工程序。自粘防水卷材出現破損或鼓泡時,應將破損部分清潔干凈后,用大于破損部位邊緣100 mm的卷材修補壓實封口。
6. quality acceptance: acceptance waterproof layer, conducted under a construction program. Self-adhesive waterproof membrane appears damaged or bubbling when damaged part should be cleaned after use damaged parts is greater than 100 mm of the edge sealing membrane repair compaction.
