Column base joint for assembly type subway station and construction method of column base joint
The invention discloses a column base joint for an assembly type subway station and a construction method of the column base joint. The column base joint comprises an upper mortise base, a lower mortise base and a plurality of energy dissipating components; the upper mortise base and the lower mortise base are vertically arranged at intervals, and the multiple energy dissipating components are evenly arranged between the upper mortise base and the lower mortise base; and a tenon-type joint is arranged at the bottom end of a prefabricated column, the upper end of the tenon-type joint is fixed to the bottom end of the prefabricated column, and the lower end of the tenon-type joint sequentially penetrates through the upper mortise base and the lower mortise base. According to the invention, the tenon-type joint is inserted into the mortise base in a penetrating mode, and on an interface of a column bottom and a foundation, rotation constraint of the foundation on the interface of the column bottom is relieved, so that the column bottom can rotate freely; by arranging the energy dissipating components, the energy dissipating components can be yielded earlier than other adjacent components, and the purpose of dissipating earthquake energy is achieved; axial force can be transmitted, the supporting effect is achieved, meanwhile, the earthquake energy can be absorbed, and the efficient anti-seismic effect is achieved; and the column base joint is clear in force transmission and has the characteristic of being replaceable when being damaged by earthquakes.
本发明公开了一种用于装配式地铁车站的柱脚节点及其施工方法，柱脚节点包括上卯眼底座、下卯眼底座及若干耗能构件；上卯眼底座与下卯眼底座上下间隔设置，若干耗能构件均匀设置在上卯眼底座与下卯眼底座之间；预制柱的底端设置有榫式接头，榫式接头的上端与预制柱的底端固定，下端依次贯穿上卯眼底座及下卯眼底座设置；本发明通过将榫式接头穿插在卯眼底座中，在柱底与基础交界面，放松基础对柱底界面的转动约束，使其能够自由转动；通过设置耗能构件，耗能构件能够先于其他相邻构件发生屈服，起到耗散地震能量的目的；不仅可以传递轴力，起到支撑作用，同时能够吸收地震能量，具有高效的抗震作用；柱脚节点传力明确，具有震损可更换的特点。
