Self-resetting column foot composed of prestressed CFRP pull rods and buckling-restrained energy consumption pipes and construction method of self-resetting column foot
The invention relates to a self-resetting column foot composed of a prestressed CFRP pull rod and a buckling-restrained energy consumption pipe, the self-resetting column foot is arranged at the bottom of a structural column, the self-resetting column foot comprises a bottom plate arranged at the bottom of the structural column, and a through hole is formed in the bottom plate; the column connecting plate is fixed to the side portion of the structural column and located above the bottom plate, and a connecting hole corresponding to the through hole is formed in the column connecting plate; the CFRP pull rod is arranged in the connecting hole and the through hole in a penetrating mode, part of the CFRP pull rod penetrates through the bottom plate to form an embedding and fixing section, external threads are formed on the surface of the embedding and fixing section, a threaded section is formed on the surface of the end, away from the embedding and fixing section, of the CFRP pull rod, and part of the threaded section penetrates through the connecting hole to form a tensioning section; the fixing nut is in threaded connection with the tensioning section, and a buckling-restrained energy consumption pipe is hinged between the bottom plate and the column connecting plate. The self-resetting column foot under the structure is good in anti-seismic effect, resetting after an earthquake can be achieved, the energy dissipation component can be replaced, and damage to a main body structure and large-range repairing and replacing after the earthquake are avoided.
本发明涉及一种预应力CFRP拉杆和防屈曲耗能管所构成的自复位柱脚，设置于结构柱的底部，所述自复位柱脚包括：设置于所述结构柱的底部的底板，所述底板形成有贯穿孔；固定于所述结构柱的侧部且位于所述底板上方的柱连接板，所述柱连接板对应所述贯穿孔形成有连接孔；穿设于所述连接孔和所述贯穿孔的CFRP拉杆，所述CFRP拉杆有部分穿过所述底板形成埋固段，所述埋固段的表面形成有外螺纹，所述CFRP拉杆远离所述埋固段的一端的表面形成有螺纹段，所述螺纹段有部分穿过所述连接孔形成张拉段；以及螺纹连接于所述张拉段的固定螺母，所述底板和所述柱连接板之间铰接有防屈曲耗能管。本发明构造下的自复位柱脚抗震效果好，能够实现震后复位，且耗能构件可更换，避免了主体结构损伤以及震后大范围的修复与更换。
