WANG XIAOPENG / XU JINJUN / ZHANG SHUYUAN / HUANG XINLIANG

The invention relates to the technical field of fabricated buildings, and discloses a fabricated Z-shaped shear wall structure and a construction method thereof.The fabricated Z-shaped shear wall structure comprises a plurality of wall limbs (2) and a plurality of intersection areas (1), the multiple wall limbs (2) are perpendicular to one another to form the Z-shaped shear wall structure, and the wall limbs (2) are detachably connected through the intersection areas (1); a plurality of constraint structures are further arranged in the wall columns (2), and the multiple constraint structures are suitable for extending to the intersection area from the interiors of the wall columns (2) so as to fixedly connect the adjacent wall columns (2). According to the method, the reinforcement mode is changed, the symmetrical corrugated stirrups are used, and the rectangular stirrups are normally arranged in the intersection area, so that the restraining effect on the longitudinal bars and the concrete is improved; the symmetrical design of the corrugated stirrups ensures the symmetry and uniformity of the wall body structure, and prevents the wall body from being stressed unevenly; by selecting the reasonable spacing and diameter of the stirrups, the constraint effect is ensured, materials can be saved, and the construction difficulty is reduced.

本发明涉及装配式建筑技术领域，公开了一种装配式Z字型剪力墙结构及其施工方法，包括多个墙肢(2)和多个交汇区(1)，多个所述墙肢(2)之间相互垂直形成Z型剪力墙结构，且各所述墙肢(2)之间经由所述交汇区(1)可拆卸地连接，所述墙肢(2)内还设有多个约束结构，多个所述约束结构适于从所述墙肢(2)内延伸至所述交汇区以固定连接相邻所述墙肢(2)。本发明能够通过改变配筋方式，并改用对称波纹箍筋，并于交叉区正常配置矩形箍筋，从而提高对纵筋与混凝土的约束效果；波纹箍筋对称式设计，保证了墙体结构的对称性及均匀性，防止墙体受力不均；通过选择合理的箍筋间距与直径，在保证约束效果的同时，又能节约用料，降低施工难度。
