Method for reserving construction joint of basement bottom plate by adopting skip bay method
The invention discloses a construction joint retention method for construction of a basement bottom plate by a skip method, which comprises the following steps of: 1, mounting a steel wire mesh and a PVC (Polyvinyl Chloride) sleeve at the construction joint of a pre-poured bottom plate, filling a waterproof material into the PVC sleeve, and sealing; secondly, concrete pouring work of a pre-poured bottom plate is conducted; 3, before binding construction of the reinforcing steel bars of the adjacent post-poured bottom plates, chiseling construction joints, cutting off exposed redundant PVC sleeves, and inserting tie bars into the PVC sleeves; fourthly, after the construction joints are cleaned, the whole surfaces of the construction joints are coated with flexible waterproof materials with the thickness being 2 mm; and fifthly, adjacent post-poured bottom plate steel bar binding and concrete pouring work is carried out. According to the invention, the telescopic lacing wires are adopted, so that the plates are allowed to deform to a certain extent; the plates are connected through flexible waterproof materials, so that the waterproof effect is ensured, and meanwhile, a small amount of deformation is allowed between the plates, and cracking is avoided.
本发明公开了一种地下室底板进行跳仓法施工的施工缝留置方法，包括：步骤一、在先浇底板的施工缝处安装好钢丝网片以及PVC套管，PVC套管内填入防水材料后封堵；步骤二、进行先浇底板的混凝土浇筑工作；步骤三、在相邻的后浇底板的钢筋绑扎施工前，将施工缝凿毛，切除外露多余的PVC套管，将拉筋插入PVC套管内；步骤四、施工缝处清理完成后，在施工缝整面涂刷2mm厚柔性防水材料；步骤五、进行相邻的后浇底板钢筋绑扎及混凝土浇筑工作。本发明采用了具有可伸缩性的拉筋，允许板块间作一定程度形变；板块间采用柔性防水材料连接，在确保防水效果的同时，允许板块间有少量形变，而不至开裂。
