Arc groove rolling shaft friction support for underground subway station supporting column
The invention discloses an arc groove rolling shaft friction support for an underground subway station supporting column. The arc groove rolling shaft friction support is mainly composed of an upper base plate, a lower base plate, a polytetrafluoroethylene arc plate and a steel rolling shaft; a long-strip-shaped arc groove is formed in the upper surface of the lower base plate, the polytetrafluoroethylene arc plate is fixedly installed in the long-strip-shaped arc groove, the steel rolling shaft is placed on the polytetrafluoroethylene arc plate, is in sliding contact with the polytetrafluoroethylene arc plate and is in rolling contact with the upper base plate, and the upper base plate and a structural top beam are poured together through welding anchor bars to form an embedded steel plate to be fixed to the bottom face of the top beam; and horizontal relative movement between the supporting column and the top beam of the underground subway station is achieved through the arc groove rolling shaft friction support, and relative horizontal deformation of the supporting column under the earthquake action can be greatly reduced by releasing joint horizontal constraint. The vertical bearing capacity is high, the steel rolling shaft is not prone to damage, production is easy, installation and maintenance are convenient, and the service life is long.
本发明公开了一种用于地下地铁车站支撑柱的圆弧凹槽滚轴摩擦支座，该装置主要由上座板、下座板、聚四氟乙烯圆弧板和钢滚轴组成。下座板的上表面设置有长条形圆弧凹槽，聚四氟乙烯圆弧板固定安装在长条形圆弧凹槽内，钢滚轴放置在聚四氟乙烯圆弧板上，分别与聚四氟乙烯圆弧板和上座板形成滑动和滚动接触，上座板通过焊接锚筋与结构顶梁一同浇注形成预埋钢板固定于顶梁底面。圆弧凹槽滚轴摩擦支座实现了地下地铁车站支撑柱与顶梁之间的水平相对运动，放开节点水平约束可大大减小地震作用下支撑柱的相对水平变形。本发明竖向承载力强，钢滚轴不易损坏，易于生产，便于安装和维修，使用寿命长。
