High-speed rail bridge damping device capable of achieving self-repairing through inertia force
The invention discloses a high-speed rail bridge damping device capable of being self-repaired through inertia force, which comprises a seismic mitigation and isolation support arranged at the top of a prefabricated pier column and damping units symmetrically arranged on two sides of the seismic mitigation and isolation support, and the damping units are respectively connected and fixed with a beam body and the prefabricated pier column through embedded components. Each damping unit comprises an upper connecting plate, a lower connecting plate and an initial energy consumption component fixedly connected between the upper connecting plate and the lower connecting plate. The limiting assembly comprises a fixed structural body connected to the bottom face of the upper connecting plate and a movable fastener connected with the fixed structural body, the standby energy dissipation component and the initial energy dissipation component are arranged in parallel, the lower end of the standby energy dissipation component is fixed to the lower connecting plate, and the upper end of the standby energy dissipation component is supported on the bottom face of the fixed structural body; when the initial energy dissipation component is sheared and damaged by earthquake energy, the movable fastener can fall under the action of inertia force to fasten and limit the standby energy dissipation component, so that the standby energy dissipation component replaces the supporting and energy dissipation effects of the initial energy dissipation component, the damping unit is self-repaired, the support is protected from being damaged, and beam falling damage is avoided.
本发明公开了一种可通过惯性力自主修复的高铁桥梁减震装置，包括设置于预制墩柱顶部的减隔震支座，及减隔震支座两侧对称布置的减震单元，减震单元分别通过预埋组件与梁体和预制墩柱连接固定。减震单元包括上、下连接板及它们之间固定连接的初始耗能构件；还包括备用耗能构件和限位组件，限位组件包括连接于上连接板底面的固定结构体和其连接的活动扣件，备用耗能构件与初始耗能构件平行设置，下端与下连接板固定，上端支撑于固定结构体的底面；初始耗能构件被地震能量剪切破坏时，活动扣件可在惯性力作用下下落将备用耗能构件扣住限位，使备用耗能构件替代初始耗能构件的支撑及耗能作用，使减震单元自修复，保护支座不被破坏及避免落梁破坏。
