Longitudinal beam falling prevention device
The invention discloses a longitudinal beam falling prevention device. The invention belongs to the technical field of bridges. The device comprises at least three groups of longitudinal energy dissipation units for connecting a bent cap and a main beam, each longitudinal energy dissipation unit comprises a first guide groove, a second guide groove, first sliding rods, a second sliding rod and a damping rod. The first guide groove is fixedly connected to the bottom of the main beam in the longitudinal direction. The second guide groove is fixedly connected to one side of the bent cap in the vertical direction. First sliding grooves allowing the first sliding rods to slide are formed in the two side walls of the first guide groove. The first sliding rods penetrate through the first slidinggrooves in the longitudinal energy dissipation units at the same time. The first sliding rods are balanced by using a self-balancing system, and a group of self-balancing system is arranged between each pair of adjacent longitudinal energy dissipation units. The device is used for being installed between a bridge pier and a bridge, excessive displacement between the bridge in the longitudinal direction is prevented, and the effects of shock absorption, energy dissipation and beam falling prevention of the bridge under the earthquake action are achieved.
本发明公开了一种纵向防落梁装置，属于桥梁技术领域，包括至少三组用于连接盖梁和主梁的纵向耗能单元，所述纵向耗能单元包括第一导槽、第二导槽、第一滑杆、第二滑杆和阻尼杆，所述第一导槽沿纵向固定连接至所述主梁的底部，所述第二导槽沿竖向固定连接至所述盖梁的一侧，所述第一导槽的两侧壁上开设有供所述第一滑杆滑动的第一滑槽，所述第一滑杆同时穿过各纵向耗能单元上的第一滑槽，所述第一滑杆通过自平衡系统平衡，相邻两组纵向耗能单元之间设置有一组所述自平衡系统，本发明装置用于安装在桥墩和桥梁之间，防止桥梁之间在纵向发生过大的位移，解决在地震作用下桥梁减震耗能防落梁的作用。
