Combined energy dissipation assembly type shear wall horizontal connecting device
The invention relates to a combined energy dissipation assembly type shear wall horizontal connecting device which is characterized in that an upper shear wall and a lower shear wall are connected through a buckling-restrained steel bar and a connecting assembly with a friction damper, and the connecting assembly comprises a lower pre-buried connecting steel plate, a friction pair and an upper pre-buried T-shaped connecting steel plate which are sequentially connected in the longitudinal horizontal direction; the upper pre-buried T-shaped connecting steel plate and the lower pre-buried connecting steel plate are connected with the upper and lower limb precast concrete shear wall through anchor bars, and a plurality of screws are arranged on the web overlapping face of the upper pre-buried T-shaped connecting steel plate and the lower pre-buried connecting steel plate. A screw rod sequentially penetrates through the lower pre-embedded connecting steel plate, the friction pair and the upper pre-embedded T-shaped connecting steel plate in the longitudinal horizontal direction and then is connected with a nut; and during connection, the two ends of the buckling-restrained steel bar are connected with concave rings at anchor plates of the upper and lower pre-embedded connecting steel plates in a surrounding welding manner. The fabricated concrete shear wall has the advantages that the structure is simple, the complexity of vertical connection of the fabricated concrete shear wall is simplified, the energy dissipation capacity of the fabricated concrete shear wall is improved, and the structure obtains more excellent anti-seismic performance and recoverability after an earthquake.
本发明涉及一种组合消能装配式剪力墙水平连接装置，上下剪力墙之间通过防屈曲钢棒和带摩擦阻尼器的连接组件连接，连接组件包括沿纵向水平方向依次连接的下预埋连接钢板、摩擦副和上预埋T型连接钢板，上预埋T型连接钢板和下预埋连接钢板通过锚筋与上下肢预制混凝土剪力墙连接，上预埋T型连接钢板和下预埋连接钢板的腹板重合面上具有若干螺杆，螺杆沿纵向水平方向依次贯穿下预埋连接钢板、摩擦副和上预埋T型连接钢板后与螺帽相连，连接时防屈曲钢棒两端分别与上下预埋连接钢板的锚板处的凹环围焊连接。本发明具有构造简单,简化装配式混凝土剪力墙竖向连接的复杂性，提高装配式剪力墙的耗能能力，使结构获得更优越的抗震性能和震后可恢复性。
