Embedded type column base joint of concrete filled steel tube composite column and construction method
The invention relates to a concrete-filled steel tube composite column embedded type column base joint and a construction method. The concrete-filled steel tube composite column embedded type column base joint comprises a concrete-filled steel tube composite column embedded section, pasting welding ring ribs, annular steel bars and stressed steel bars. The welding ring ribs are coaxially arranged on the outer wall of the steel tube of the embedded section of the concrete-filled steel tube composite column along the column height direction of the composite column, and are subjected to full-length full-length welding or intermittent welding; the load-bearing steel bar is provided with a cut-off area matched with the embedded section of the concrete-filled steel tube composite column, and the embedded section of the concrete-filled steel tube composite column is inserted into the cut-off area of the load-bearing steel bar. The annular reinforcing steel bars are arranged corresponding to the elevation of the stressed reinforcing steel bars and coaxially and annularly arranged outside the steel pipe; the load-bearing steel bars are buckled to the annular steel bars, the inner sides of the load-bearing steel bars abut against the pasting and welding annular steel bars, a lap joint plate or a lap joint bracket does not need to be additionally arranged, the connecting mode is simple, anchoring is safe and reliable, and the steel consumption and the field welding amount are reduced. And the pipe outside welding ring ribs with higher linear rigidity are arranged to replace studs, so that the bonding of the interface of the outer wall of the steel pipe is enhanced, the internal force at the bottom of the column is favorably diffused to the foundation, the integrity is better, and the influence on the insertion and placement of the longitudinal stirrups of the column is smaller.
本发明涉及一种钢管混凝土叠合柱埋入式柱脚节点及施工方法，钢管混凝土叠合柱埋入式柱脚节点包括钢管混凝土叠合柱埋入段、贴焊环筋、环形钢筋、受力钢筋；贴焊环筋沿叠合柱的柱高方向同轴向设置在钢管混凝土叠合柱埋入段的钢管外壁上，通长满焊或间断焊；受力钢筋设有与钢管混凝土叠合柱埋入段相适应的截断区，钢管混凝土叠合柱埋入段插入于受力钢筋的截断区内；环形钢筋对应受力钢筋标高设置，和钢管同轴环设于钢管外；受力钢筋卡扣于环形钢筋且其内侧抵接于贴焊环筋，不需另设搭接板或搭接牛腿，连接方式简单、锚固安全可靠，减少用钢量和现场焊接量。设置线刚度更大的管外贴焊环筋代替栓钉，加强钢管外壁界面的粘结，有利于柱底内力向基础扩散，整体性更好，对柱纵筋箍筋的穿插摆放影响更小。
