Prefabricated concrete-filled steel tube composite column and construction method
The invention belongs to the technical field of buildings, and discloses a prefabricated concrete-filled steel tube composite column and a construction method. The prefabricated concrete-filled steel tube composite column comprises common concrete, a steel tube, a longitudinal bar, a crossed spiral stirrup net, high-performance concrete UHPC and a prestressed steel belt. Round steel belt hoops formed by surrounding prestressed steel belts are arranged on the outer surface of the steel pipe at equal intervals. Four longitudinal bars with the same length as the steel pipe are arranged around the steel pipe at equal intervals in the column length direction; a crossed spiral stirrup net is wound on the outer surfaces of the four longitudinal bars; the steel pipes are filled with the common concrete, and the exteriors of the steel pipes, the longitudinal bars and the crossed spiral stirrup net are poured by the high-performance concrete to form a cuboid. According to the construction method, partial prefabrication and partial cast-in-place are adopted, manufacturing of the prefabricated part of the concrete-filled steel tube composite column is completed in a factory, and only concrete in the steel tube needs to be poured on site. The structure is excellent in performance, convenient and fast to construct and remarkable in economic benefit.
本发明属于建筑技术领域，公开了一种预制装配钢管混凝土叠合柱及施工方法。其中，预制装配钢管混凝土叠合柱，包括普通混凝土、钢管、纵筋、交叉螺旋箍筋网、高性能混凝土UHPC、预应力钢带；钢管的外表面等间距设置有预应力钢带环绕形成的圆形钢带箍；钢管的四周沿柱长方向等间距设置有四根与钢管等长的纵筋；四根纵筋的外表面缠绕设置有交叉螺旋箍筋网；普通混凝土填充于钢管的内部，钢管的外部连同纵筋与交叉螺旋箍筋网被高性能混凝土浇筑形成长方体。本发明的施工方法采用部分预制装配部分现浇，在工厂完成钢管混凝土叠合柱预制部分的制作，在现场只需浇筑钢管内部混凝土即可完成。本发明结构性能优良，施工方便快捷，经济效益显著。
