Self-resetting and replaceable steel reinforced concrete prefabricated assembled middle column and construction method
The invention relates to a self-resetting and replaceable steel reinforced concrete prefabricated assembled middle column and a construction method, the self-resetting and replaceable steel reinforced concrete prefabricated assembled middle column comprises a top plate, a bottom plate and a middle column, the middle column is of a prefabricated steel reinforced concrete structure, and an upper flange assembly is arranged between the upper end of the middle column and the top plate; the upper flange assembly comprises an upper flange seat, an upper steel base plate and an upper flange plate, the upper flange seat sleeves the upper end of the middle column, the upper flange plate is arranged above the top plate, and a bolt is arranged between the upper flange plate and the upper flange seat; a lower flange assembly is arranged between the lower end of the middle column and the bottom plate and comprises a lower flange seat and a lower steel base plate, the lower flange seat sleeves the lower end of the middle column, and an embedded memory alloy rod is arranged between the lower flange seat and the bottom plate; longitudinal steel bars are further arranged between the upper steel base plate and the lower steel base plate and vertically penetrate through the middle column. While the structural strength of the center pillar is improved, the anti-seismic performance of the center pillar can be improved, structural damage during an earthquake is reduced, the center pillar can be self-reset and rapidly replaced after the earthquake, and post-disaster reconstruction is facilitated.
本发明涉及自复位且可更换的型钢混凝土预制拼装中柱及施工方法，包括顶板、底板和中柱，中柱为预制的型钢混凝土结构，中柱上端和顶板之间设置有上法兰组件；上法兰组件包括上法兰座、上钢垫板和上法兰板，上法兰座套设在中柱上端，上法兰板设置在顶板上方，上法兰板和上法兰座之间设置有螺栓；中柱下端和底板之间设置有下法兰组件，下法兰组件包括下法兰座和下钢垫板，下法兰座套设在中柱下端，下法兰座和底板之间设置有预埋记忆合金杆；上钢垫板和下钢垫板之间还设置有纵向钢筋，纵向钢筋竖向贯穿中柱。本发明在提高中柱结构强度的同时，能提高其抗震性能，减小震时结构损伤，在震后可自复位和快速更换，方便灾后重建。
