Beam end replaceable energy consumption device of beam column joint
The invention provides a beam end replaceable energy consumption device of a beam column joint, which comprises an embedded steel plate and a metal damper, and the embedded steel plate is embedded at the end part of a steel bar of a precast concrete beam; the metal damper is mounted between the embedded steel plates of the two butted precast concrete beams; the end part of a reinforcing steel bar in the precast concrete beam is in threaded connection with the threaded sleeve, and the embedded steel plate is fixedly connected with the threaded sleeve; the metal damper comprises perforated H-shaped steel, an end plate, a restraint plate, a filling plate and a dumbbell-shaped steel plate. The metal damper and the perforated H-shaped steel are connected with the prefabricated concrete beam through high-strength bolts and can be quickly replaced after an earthquake; the post-earthquake recoverable function of the beam-column joint of the fabricated concrete frame structure is achieved, the post-earthquake repair time of the structure is saved, and the full-life-cycle high benefit of the fabricated concrete structure is achieved.
本发明提供一种梁柱节点的梁端可更换耗能装置，包括预埋钢板和金属阻尼器，所述的预埋钢板埋置在预制混凝土梁的钢筋端部；金属阻尼器安装在两个对接的预制混凝土梁的预埋钢板之间；预制混凝土梁中的钢筋端部与螺纹套筒螺纹连接，所述的预埋钢板与螺纹套筒固定连接；所述的金属阻尼器，包括开孔H型钢、端板、约束板、填充板和哑铃型钢板。本发明金属阻尼器和开孔H型钢均采用高强螺栓与预制混凝土梁连接，震后可快速更换；实现了装配式混凝土框架结构梁柱节点的震后可恢复功能，节省了结构震后修复时间，实现装配式混凝土结构全寿命周期高效益。
