Prestressed prefabricated concrete shear wall system and construction method thereof
The invention provides a prestressed prefabricated concrete shear wall system and a construction method thereof. The prestressed prefabricated concrete shear wall system comprises prefabricated shearwalls and prestressed reinforcements; the transversely adjacent prefabricated shear walls are connected with each other through tongues and grooves; reinforcement through passages are formed in the prefabricated shear walls; anchor bearing plates are buried in positions, corresponding to the reinforcement through passages, at the tops of the prefabricated shear walls; through holes and grout outlets are formed in the anchor bearing plates; gaps are reserved in the bottoms of the prefabricated shear walls; the gaps communicate with the reinforcement through passages; the prestressed reinforcements penetrate through the reinforcement through passages; a first reinforcement connector at the top of the prefabricated shear wall in the lower layer is correspondingly inserted in the gap of the prefabricated shear wall in the upper layer and is connected with the gap through the first reinforcement connector; the gap is filled with a filling material; a grouting pipeline is buried in the filling material; and passage grouting materials are poured in the reinforcement through passages. According to the prestressed prefabricated concrete shear wall system and the construction method thereof,the technical problems of high making accuracy requirement, high quality control difficulty, lack of effective grouting quality detection means, difficult member transportation, multiple site wet operations and longer construction period of a traditional prefabricated shear wall are solved.
一种预应力装配式混凝土剪力墙体系及其施工方法，包括预制剪力墙和预应力钢筋；横向相邻的预制剪力墙通过企口连接；预制剪力墙内部设有穿筋孔道；预制剪力墙的顶部、对应穿筋孔道的位置处埋有锚垫板；锚垫板上开有穿孔和出浆孔；预制剪力墙底部留有豁口，豁口与穿筋孔道相贯通；穿筋孔道中穿有预应力钢筋；下层预制剪力墙顶部的第一钢筋连接器对应插在上层预制剪力墙的豁口中，且通过第一钢筋连接器连接；豁口处填有填充料，在填充料中埋设有注浆管道；穿筋孔道中灌注有孔道灌浆料。本发明解决了传统的装配式剪力墙制作精度要求高、质量控制难度大、同时缺乏对灌浆质量有效的检测手段、构件运输困难、现场湿作业多以及施工周期较长的技术问题。
