Detachable and replaceable precast concrete beam-column joint and preparation method
The invention discloses a detachable and replaceable prefabricated concrete beam-column joint and a preparation method. The detachable and replaceable prefabricated concrete beam-column joint comprises a prefabricated reinforced concrete column with a beam end, a prefabricated concrete beam and an embedded steel plate embedded in the beam end. A replaceable energy consumption device is fixedly connected between the embedded steel plates; the replaceable energy consumption device comprises a pair of horizontal metal dampers which are arranged up and down, and a vertical energy consumption steel plate is arranged between the metal dampers. The replaceable energy dissipation device and the perforated H-shaped steel are connected with the other parts through bolts, disassembly and replacement are convenient, connection is reliable, meanwhile, the stable ductile energy dissipation capacity of the metal energy dissipation assembly can be exerted, damage is only concentrated on the energy dissipation assembly, replacement can be conveniently and rapidly conducted after a strong earthquake, and the energy dissipation assembly is convenient to use. And the function of the fabricated concrete frame structure can be quickly recovered after an earthquake.
可拆卸更换预制混凝土梁柱节点及制备方法，包括带梁端的预制钢筋混凝土柱、预制混凝土梁、埋置在梁端的预埋钢板；预埋钢板之间固定连接可更换耗能装置；所述的可更换耗能装置包括上下设置的一对水平的金属阻尼器，一对金属阻尼器之间设有垂直的耗能钢板。本发明中可更换耗能装置和开孔H型钢与其余各个部分的连接均采用螺栓连接，便于拆卸更换，连接可靠，同时能够发挥金属耗能组件的稳定的延性耗能能力，将损伤仅仅集中在耗能组件，强震后能够方便快速地更换，实现装配式混凝土框架结构的震后功能快速恢复。
