Fabricated energy-dissipation self-resetting column foot structure and stand column connecting joint
The invention discloses a fabricated energy-dissipation self-resetting column foot structure and a stand column connecting joint. A top groove and a bottom spherical groove are formed in the top and the bottom of an upper column sleeve; a spherical support is installed in the center of a bottom box groove, and the upper portion of the spherical support is embedded into the bottom spherical groove; the spherical support is connected with the upper column sleeve through a prestressed tie bar bolt; a plurality of elastic energy-dissipation supporting sleeves are evenly arranged in the circumferential direction of the spherical support, one end of each elastic energy-dissipation supporting sleeve is connected with the bottom box groove, and the other end of each elastic energy-dissipation supporting sleeve is connected with the upper column sleeve; a plurality of springs are evenly arranged at the bottom of the upper column sleeve in the circumferential direction, and the two ends of each spring are connected or make contact with the upper column sleeve and the bottom box groove correspondingly; and a plurality of fabricated corrugated energy-dissipation steel plates are evenly arranged in the circumferential direction of the upper column sleeve, and the two ends of each fabricated corrugated energy-dissipation steel plate are detachably connected with the bottom box groove of the upper column sleeve. The structure can achieve graded shock resistance, and is convenient to disassemble and assemble and rapid to replace.
本发明公开了一种装配式耗能自复位柱脚结构及立柱连接节点，上部柱套筒的顶部和底部设置有顶部凹槽和底部球形凹槽；球形支座安装于底部箱槽的中心，上部嵌入底部球形凹槽内；球形支座与上部柱套筒之间通过预应力拉筋螺栓连接；球形支座的周向均匀设有若干弹性耗能支撑套筒，弹性耗能支撑套筒的一端与底部箱槽连接，另一端与上部柱套筒连接；上部柱套筒的底部沿周向均匀设有若干弹簧，弹簧的两端分别与上部柱套筒和底部箱槽连接或接触；上部柱套筒的周向均分设有若干装配式波纹耗能钢板，装配式波纹耗能钢板的两端分别与上部柱套筒底部箱槽之间可拆卸连接。本发明的结构能够实现分级抗震、拆装方便、更换迅速。
