The invention relates to a connection structure of a vertical joint of a composite shear wall. In the present invention, horizontal stirrups are arranged in the vertical joints of adjacent composite shear walls along the height direction of the wall, and the horizontal steel bars in the inner and outer laminated layers of the composite shear walls are extended to a certain length in the vertical joints, then bended and rotated to extend to the cavity layer of the composite shear walls to form semi-open circular horizontal steel bars, and the horizontal stirrups in the vertical joints are laid on the semi-open circular ones. Horizontal reinforcing bars are tied up to form multiple closed hoops. Vertical loaded reinforcing bars are inserted into the closed hoops. Concrete is poured into the cavity layer of composite wall slabs and vertical joints to anchor the semi-open circular horizontal reinforcing bars. In the present invention, by inserting the vertical force reinforcement into the formed closed hoop, a reliable connection is formed between the post-poured concrete in the vertical joint and the overlapping shear wall on both sides, the coordinated deformation ability of the two is improved, and the overall mechanical performance of the two is guaranteed.

一种叠合剪力墙竖向拼缝的连接构造
本专利技术涉及建筑
,尤其涉及一种叠合剪力墙竖向拼缝的连接构造。
技术介绍
叠合剪力墙结构作为一种装配式建筑结构体系,具有安装轻便、整体性能好的优点,应用前景广阔。相邻两叠合剪力墙预制构件之间存在竖向拼缝,竖向拼缝设置混凝土后浇段。叠合剪力墙竖向拼缝的连接构造是将两片相邻的叠合剪力墙预制构件与中间竖向混凝土后浇段水平连接成整体叠合剪力墙的一种水平连接构造措施。传统的叠合剪力墙预制构件中,叠合剪力墙竖向拼缝的连接构造主要是采用空腔层另设钢筋搭接的形式,叠合剪力墙内水平钢筋不外伸。采用该种连接技术的叠合剪力墙,虽然构件的制作较为便利,但是连接构造有一定的不足,包括:(1)叠合剪力墙内、外叶预制叠合层在竖向拼缝左右两侧存在竖向通缝,水平连接钢筋“内收”,连接作用和结构整体性有一定的削弱;(2)另设钢筋现场定位绑扎不易控制,无法有效地保证竖向拼缝连接的可靠性。
技术实现思路
针对上述问题,现提供一种受力合理且连接可靠的叠合剪力墙竖向拼缝的连接构造。具体技术方案如下:一种叠合剪力墙竖向拼缝的连接构造,具有这样的特征,在相邻叠合剪力墙的竖向拼缝中沿墙高方向设置水平箍筋,将叠合剪力墙中内、外叶叠合层中的水平钢筋延伸至竖向拼缝中一定长度后再弯折并回转延伸至叠合剪力墙的空腔层中形成半开放式环状水平钢筋,将竖向拼缝中的水平箍筋搭放在半开放式环状水平钢筋上并绑扎形成多个封闭状套箍,在封闭状套箍中插入竖向受力钢筋,向叠合剪力墙空腔层及竖向拼缝中浇筑混凝土以将水平箍筋、半开放式环形水平钢筋及竖向受力钢筋锚固并将相邻叠合剪力墙连接形成整体。上述的叠 ...
