Superimposed shear wall longitudinal and transverse wall connecting joint structure with concentrated reinforcements in vertical post-cast section
The invention discloses a superimposed shear wall longitudinal and transverse wall connecting joint structure with concentrated reinforcements in a vertical post-cast section. A small-size vertical post-cast section with the width equal to the thickness of a wall body is arranged at the connecting position between a longitudinal wall and a transverse wall, and vertical steel bars with large diameter are arranged in the vertical post-cast section in a concentrated mode to guarantee the bending resistance of the wall body; small-diameter vertical constructional steel bars are arranged in prefabricated wall edge component areas, edge component vertical steel bars with common specifications are not arranged, and additional connecting steel bars or large-diameter vertical steel bars are arranged in a cavity to achieve connection between the upper-layer prefabricated wall edge component area and the lower-layer prefabricated wall edge component area; and stirrups or tie bars are arranged inthe vertical post-cast section and the prefabricated wall edge component areas correspondingly to form partition constraint on concrete of the vertical post-cast section and the prefabricated wall edge component areas, the elastoplastic deformation capacity of the wall body is guaranteed, horizontal connecting steel bars are arranged among the vertical post-cast section and the prefabricated walledge component areas in a penetrating mode to achieve tying, and integral edge components are formed after post-cast concrete is poured. The superimposed shear wall longitudinal and transverse wall connecting joint structure with the concentrated reinforcements in the vertical post-cast section can effectively solve the problems of large size of the vertical post-cast section of the longitudinal and transverse wall connection joint of an existing superimposed shear wall, difficulty in binding the steel bars, difficulty in vibrating the concrete and the like.
本发明公开了一种竖向后浇段集中配筋的叠合剪力墙纵横墙连接节点构造，纵横墙连接位置设置宽度与墙体厚度等同的小尺寸竖向后浇段，竖向后浇段内集中配置直径较大的竖向钢筋保证墙体的抗弯能力；预制墙边缘构件区域配置小直径的竖向构造钢筋，不配置普通规格的边缘构件竖向钢筋，在空腔内布设附加连接钢筋或大直径竖向钢筋实现上下层预制墙边缘构件区域的连接；竖向后浇段、预制墙边缘构件区域分别配置箍筋或拉筋对其混凝土形成分区约束，保证墙体的弹塑性变形能力，二者间穿设水平连接钢筋实现拉结、浇筑后浇混凝土后形成整体边缘构件。本发明可有效解决目前叠合剪力墙纵横墙连接节点竖向后浇段尺寸大、钢筋绑扎困难及混凝土难以振捣等问题。
