Self-resetting fabricated concrete shear wall device and construction method thereof
The invention discloses a self-resetting assembly type concrete shear wall device which comprises an assembly type concrete shear wall I, an assembly type concrete shear wall II, a shear type energy consumption section and a self-resetting connector. The fabricated concrete shear wall I comprises end longitudinal bars I, sleeve longitudinal bars I, middle longitudinal bars I, grouting sleeves and embedded components; the assembly type concrete shear wall II comprises end longitudinal bars II, sleeve longitudinal bars II, middle longitudinal bars II and embedded components. Energy dissipation capacity and self-resetting capacity are provided through self-resetting connection of the bottoms of the left side and the right side, and concrete at the bottoms of the two sides is prevented from being damaged under the tension effect; meanwhile, the shear type energy dissipation section at the bottom of the middle can provide enough shear bearing capacity for the fabricated concrete beam force wall, it is guaranteed that shear damage cannot happen after wall bodies on the two sides of the bottom of the shear wall are weakened, and the shear type energy dissipation section has the advantages of being reasonable in stress, simple in structure, good in anti-seismic performance, high in self-resetting capacity, small in damage after an earthquake and the like.
本发明公开了一种自复位装配式混凝土剪力墙装置，包括装配式混凝土剪力墙Ⅰ、装配式混凝土剪力墙Ⅱ、剪切型耗能段、自复位连接；装配式混凝土剪力墙Ⅰ包括端部纵筋Ⅰ、套筒纵筋Ⅰ、中间纵筋Ⅰ、灌浆套筒、预埋构件；装配式混凝土剪力墙Ⅱ包括端部纵筋Ⅱ、套筒纵筋Ⅱ、中间纵筋Ⅱ、预埋构件。本发明通过左右两侧底部的自复位连接提供耗能能力和自复位能力，并防止两侧底部混凝土在受拉作用下发生破坏；同时中间底部的剪切型耗能段可为装配式混凝土梁力墙提供足够的受剪承载能力，保证剪力墙底部两侧墙体削弱后仍不会发生受剪破坏，具有受力合理、构造简单、抗震性能好、自复位能力强、震后损伤小等特点。
