Frame type replaceable buckling-restrained damping energy dissipation device and usage method
The invention provides a frame type replaceable buckling-restrained damping energy dissipation device and relates to the technical field of assembly-type bridge seismic resistance, seismic mitigationand isolation devices and seismic mitigation and disaster reduction high-performance quick repair building materials. The device comprises an upper energy dissipation steel bar joint, a mechanical connecting part, an energy dissipation steel bar, a frame-type limiting connecting mechanism, a connecting nut and a lower energy dissipation steel bar joint, the usage method of the frame type replaceable buckling-restrained damping energy dissipation device comprises a pre-earthquake installation step and a post-earthquake replacement step. According to the invention, the energy consumption capability of the segmental assembled pier can be improved; the problem that the built-in energy-consuming steel bars are not easy to repair after an earthquake can be solved; by means of the structure, theuse function of the damaged pier after an earthquake is quickly repaired, the energy dissipation steel bars can be prevented from being pressed and bent through the frame type buckling-restrained connection, the problem that the replaceable energy dissipation steel bars are prone to being pressed and bent under the earthquake action, and consequently the anti-seismic property of the replaceable energy dissipation steel bars cannot be fully achieved is solved, and the anti-seismic property of the segmental assembled pier is improved.
一种框架式可更换防屈曲减震耗能装置，涉及装配式桥梁抗震及减隔震装置及抗震减灾高性能快速修复建材技术领域，包括上耗能钢筋接头、机械连接件、耗能钢棒、框架式限位连接机构、连接螺母、下耗能钢筋接头；一种框架式可更换防屈曲减震耗能装置的使用方法：包括震前安装步骤及震后更换步骤。本发明不仅能够提高节段拼装桥墩的耗能能力，而且可以解决内置耗能钢筋震后不易修复的问题，实现受损桥墩震后使用功能的快速修复，通过框架式防屈曲连接能够防止耗能钢棒受压屈曲，进而解决可更换的耗能钢棒在地震作用下容易受压屈曲致不能充分发挥其自身的抗震性能的问题，提升节段拼装桥墩的抗震性能。
