厚塑料薄膜做隔離層,按照6m*6m 進行彈線分隔,固定好分隔條,然后按照排水坡度進行沖筋,根據甲方通知放好 6200 雙向鋼筋網片，注意鋼筋在分隔條處斷開，鋼筋網片盡可能偏向上部，用墊塊調整。然后澆灌C20 細石砼，注意不得用機械振搗，以免破壞防水層，表面原漿壓光。沿女兒墻周邊25cm留設一條分隔縫，分隔縫寬度為20mm。7、隔熱磚施工：待保護層初凝，取出分隔條，待保護層達到一定ndoverallleadershipresponsibilityforsafety.AdministrativeDeputyiswit

水泥砂漿坐砌隔熱磚。隔熱磚距女兒墻內邊不少于250。六、注意事項：1、基層表面應清潔光滑平整，無滲漏，無積水，嚴禁帶水、帶泥施工。平整度用 2M 直尺檢查，最大空隙不應大于5mm，不得有空鼓、開裂及起砂、脫皮等缺陷，空隙只允許平緩。陰角處應做成直徑 50mm的圓角。陽角處應做成直徑 10mm 圓角，角度應為135o，其邊長不小于 12cm。2、如基層為混泥土25、結構而且不平整，可進行局部修補整平，然后滿刮一道 HQB 高分子防水劑，將氣孔、小孔堵塞平整。不得在特別潮濕、不通風的環境下施工，否則會影響成膜質量。4、基層應堅實，平整光滑，均勻一致，無空鼓、凹坑以及掉皮起砂等現象。5、涂層分多次進行，力求均勻，切不可出現漏涂現象，一定要待前一次涂的材料成膜，方可進行下一次涂刷工作，前后兩次間隔時間具體視氣溫高低、空氣濕度大小而定，涂刷方向要垂直，直到防水層達到 2mm 為止。七、產品保護：1、涂膜完成后，不得隨意刻劃涂膜表面，不得持任何硬物在涂膜上拖行，不得堆放重物、硬物。2、當立壁涂膜采用水泥漿保護層則要在最后一遍涂膜固化前，撒上一層干砂，以利于增強與水26、泥砂漿保護層的粘結力。3、常見質量問題：ndoverallleadershipresponsibilityforsafety.AdministrativeDeputyiswit

氣孔、氣泡：材料攪拌方式及攪拌時間未使材料拌合均勻，施工時，基層處理不干凈，做涂層前應仔細清理基層，不得有浮砂和灰塵，基層上更不應有孔隙，涂膜各層出現的氣孔應按工藝要求處理，防止涂膜破壞造成滲漏。b 起鼓：基層有起皮、起砂、開裂、積水31、，使涂膜粘結不良，基層施工應認真操作、保養，待基層符合防水施工要求后，先涂底層涂料，固化后，再按防水層施工工藝逐層涂刷。c 涂膜翹邊：防水層的邊沿、分項刷的搭接處、出現同基層剝離翹邊現象。主要原因是基層不潔凈或積水，收口操作不細致，密封不好，底層涂料不粘。d 破損：涂膜防水分層施工過程中或全部涂膜施工完，未等涂膜固化就上人操作活動，或放置工具材料等，將涂膜破環、劃傷，施工中應保護涂膜的完整。八、工程質量驗收標準檢驗項目要求檢驗方法主控項目防水涂料和胎體增強材料必須符合設計要求檢查出廠合格證、質量檢驗報告和現場抽檢報告涂膜防水層不得有滲漏或積水現象.雨后或淋雨、蓄水試驗。涂膜防水層在天面、檐溝、32、檐口、水落口、變形縫和伸出屋面管道等處細部做法必須符合設計要求觀察檢查和檢查隱蔽工程驗收記錄表ndoverallleadershipresponsibilityforsafety.AdministrativeDeputyiswit
