Construction method of steel pipe concrete superposed column
The invention discloses a construction method of a steel pipe concrete superposed column. The construction method comprises the following steps: S1, carrying out deep design on a steel structure of asuperposed column, and manufacturing a steel pipe column; S2, carrying out measuring positioning and foundation bolt embedding in the construction position of the superposed column; S3, pouring a concrete bearing platform; S4, installing the steel pipe column on the bearing platform and correcting; and S5, carrying out non-shrinkage concrete seam filling between the top surface of the bearing platform and steel pipe column pins. Stirrup connecting plates are arranged on the outer wall of the steel pipe in the scope of the pins, so that the construction problem of the connection between embedded column pins stirrups and a steel pipe is solved, and the transmission of the structure stress. By adopting a process non-woven fabric flexible guide pipe to replace a rigid guide pipe, the problem that because the steel pipe concrete superposed column is dense, the guide pipe cannot send the concrete to the column bottom is solved, and the pouring quality of the concrete is guaranteed. Transverse positioning steel bars are welded to the steel pipe column, so that the deflection of longitudinal stress steel bars in the construction process is avoided, and the thickness of a steel bar protective layer is guaranteed.
本发明公开一种钢管混凝土叠合柱施工方法，包括以下步骤：S1：对叠合柱的钢结构进行深化设计，制作钢管柱；S2：在叠合柱施工位置进行测量定位及地脚螺栓埋置；S3：浇筑混凝土承台；S4：在承台上安装钢管柱并校正；S5：在承台顶面与钢管柱柱脚之间进行无收缩混凝土灌缝；钢管外壁在柱脚范围内设置箍筋连接板，解决了埋入式柱脚箍筋与钢管连接的施工难题，保证结构受力的传递。采用工艺无纺布柔性导管替代刚性导管，解决了钢管混凝土叠合柱钢筋密集，导管无法将混凝土送至柱底的问题，保证了混凝土的浇筑质量。在钢管柱上焊接横向定位钢筋，避免施工过程中纵向受力钢筋偏位，保证钢筋保护层厚度。
