Anti-beam-falling device based on multi-stage energy consumption and using method of anti-beam-falling device
The invention discloses a beam falling prevention device based on multi-stage energy consumption and a using method of the beam falling prevention device. A friction damper comprises a first connecting piece, a second connecting piece and an energy consumption part. The first connecting piece is fixedly arranged on one side of the bridge pier; the second connecting piece is fixedly arranged at the bottom end of the bridge superstructure; the two ends of the energy dissipation component are connected with the first connecting piece and the second connecting piece respectively. The energy dissipation component comprises a rigging and a damping component. The energy dissipation component is firmly fixed to the proper position of the bridge through the first connecting piece and the second connecting piece, and meanwhile in the bridge vibration process, the energy dissipation component is firmly fixed to the proper position of the bridge. Through the rigging and the damping component, the purposes that the rigging is tensioned from a static state, the interior of the damping component rotates to play a rotating type friction damping role, and parts in the damping component enter a yield state to play a multi-stage energy dissipation damping role are achieved step by step, the overall length of the anti-beam-falling device is effectively shortened, and the anti-beam-falling effect is improved. Therefore, the problems of large installation space requirement and downwarping of the damper are solved.
本发明公开了一种基于多阶段耗能的防落梁装置及其使用方法，该摩擦阻尼器包括：第一连接件、第二连接件及耗能部件；所述第一连接件固定设于桥墩一侧；所述第二连接件固定设于桥梁上部结构底端；所述耗能部件两端分别与所述第一连接件及所述第二连接件连接，其包括：索具及阻尼部件；通过所述第一连接件及所述第二连接件将所述耗能部件牢固固定在桥梁合适位置，同时，在桥梁震动过程中，通过所述索具及所述阻尼部件逐步实现包括所述索具由静态到拉紧、所述阻尼部件内部转动发挥转动型摩擦阻尼作用、以及所述阻尼部件内零部件进入屈服状态的多阶段耗能减震作用，有效缩短所述防落梁装置整体长度，进而解决安装空间要求大和阻尼器下挠的问题。
