Column foot connection of novel cold-formed thin-walled concrete filled steel tubular column and construction method thereof
The invention discloses a novel cold-formed thin-walled concrete filled steel tubular column foot connection and a construction method thereof, a steel tubular column is vertically arranged on a ground foundation, a bottom plate is arranged below the steel tubular column and above the ground foundation, a positioning hole penetrating through two opposite side walls of the bottom plate is formed in the bottom plate, and the steel tubular column is located above the positioning hole; a plurality of fixing holes are formed in the periphery of the bottom plate, and the positioning anchor bolts penetrate through the fixing holes, then extend into the foundation and are fixedly connected with the bottom plate through fixing nuts; a plurality of connecting pieces are vertically arranged in the steel pipe column, the connecting pieces are distributed along the periphery of the steel pipe column at intervals, the length direction of the connecting pieces is consistent with that of the steel pipe column, and one side of each connecting piece is fixedly connected with the inner side wall of the steel pipe column; a lap joint longitudinal bar is arranged between every two adjacent connecting pieces, the length direction of the lap joint longitudinal bars is consistent with the length direction of the steel pipe column, the upper ends of the lap joint longitudinal bars extend into the steel pipe column, and the lower ends of the lap joint longitudinal bars penetrate through positioning holes in the bottom plate and then are inserted into the foundation.
本发明公开了一种新型冷弯薄壁钢管混凝土柱的柱脚连接及其施工方法，在地面基础上竖向设置一钢管柱，在钢管柱的下方、地面基础上方设有一底板，在底板上设有一贯穿底板相对两侧壁的定位孔，所述钢管柱位于该定位孔的上方；在底板上绕其一周设有多个固定孔，定位锚栓穿过固定孔后伸入基础内，并通过固定螺母与底板固定相连；在钢管柱内竖向设置有多根连接件，所述连接件沿钢管柱一周间隔分布，且连接件的长度方向与钢管柱的长度方向一致，连接件的一侧与钢管柱的内侧壁固定相连；在相邻两根连接件之间设有一搭接纵筋，所述搭接纵筋的长度方向与钢管柱的长度方向一致，且搭接纵筋的上端延伸至钢管柱内部，其下端穿过底板上的定位孔后插入基础内。
