The present invention relates to an extrusion sleeve connection composite shear wall and its construction method. The shear wall consists of two concrete prefabricated leaf slabs and truss steel bars connecting the two leaf slabs. The prefabricated concrete leaf slabs are equipped with horizontal and vertical distributed reinforcement bars. The vertical distributed reinforcement bars extend 15 30cm from the upper and lower ends of the wall slabs, and the vertical distributed reinforcement bars of the composite shear wall slabs are opposite to each other in the vertical direction. Thirdly, the vertical distributed steel bars of shear walls are connected by extrusion sleeves. The advantages are that the vertical distributed reinforcing bars of the upper and lower composite shear wall panels are connected by extrusion sleeves, which is a mechanical connection mode of reinforcing bars. The vertical distributed reinforcing bars are continuous in longitudinal direction, have good force transmission effect, have high engineering reliability, and the construction height can be equivalent to the cast-in-situ shear wall structure. The construction of extrusion sleeve connection is realized by cold extrusion of steel sleeves with hydraulic clamps to realize the connection of vertical distributed reinforcing bars of shear The construction speed is fast, and the extrusion force can be controlled according to the pressure value of hydraulic clamp, so the connection quality of steel bar has engineering reliability.

挤压套筒连接叠合剪力墙及其工法
本专利技术属于装配式建筑领域,涉及叠合剪力墙的竖向连接,具体涉及挤压套筒连接双面叠合剪力墙及其工法。
技术介绍
叠合剪力墙由两面预制混凝土叶板、连接于两面预制混凝土叶板之间的桁架钢筋和后浇混凝土叠合层组成。叠合剪力墙结构的建造过程主要包括:①预制混凝土墙板在工厂制作、养护;②预制混凝土墙板达到设计强度后运至施工现场,连接安装就位;③浇筑后浇混凝土叠合层,并使结构形成整体。工程应用表明,该类剪力墙体系具有较好的整体性能,节省现场模板和支撑,便于工业化生产,综合经济效益较好。叠合剪力墙结构融合了预制和现浇的优点,施工便捷,受力性能等同现浇结构,可以在装配式住宅市场大力推广。现有连接方式中叠合剪力的竖向分布钢筋采用空腔插筋连接,在后浇混凝土10cm空腔内设置插筋与预制叶板内的竖向分布钢筋进行间接连接,力的传递是依靠混凝土与钢筋之间的握裹力实现,较钢筋搭接、机械连接等连接方式传力效果不明确。
技术实现思路
