Novel corrugated pipe connection square steel pipe concrete splicing column
The invention discloses a novel corrugated pipe connection square steel pipe concrete spliced column. The novel corrugated pipe connection square steel pipe concrete spliced column comprises a prefabricated upper column section and a prefabricated lower column section. A reinforcement cage and concrete are arranged in a first outer steel pipe of the prefabricated upper column section, the lower ends of longitudinal bars of the reinforcement cage extend out of the first outer steel pipe, and a distance exists between the concrete and the lower end of the first outer steel pipe. A second outer steel pipe of the prefabricated lower column section is provided with concrete and a corrugated pipe, a distance exists between the concrete and the upper end of the second outer steel pipe, and the corrugated pipe is embedded in the concrete and flush with the upper end face of the second outer steel pipe. In the splicing state, the longitudinal bars are inserted into the corrugated pipes correspondingly, the first outer steel pipe and the second outer steel pipe are welded, and cavities in the connecting positions are filled with cementing materials. The concrete filled steel tubular column butt joint connection node adopts the reinforcement cage and the corrugated pipe slurry anchor for connection, the process can be simplified, the cost can be reduced, the construction efficiency can be effectively improved, and the concrete filled steel tubular column butt joint connection node can be widely applied to assembly type structure systems.
本发明公开了一种新型波纹管连接方钢管混凝土拼接柱，包括预制上柱段和预制下柱段。预制上柱段的第一外钢管内设置钢筋笼和混凝土，钢筋笼的纵筋下端伸出第一外钢管，混凝土与第一外钢管的下端存在距离。预制下柱段的第二外钢管设置混凝土和波纹管，混凝土与的第二外钢管上端存在距离，波纹管预埋混凝土内并与第二外钢管上端面齐平。拼接状态时，纵筋分别插入波纹管，第一外钢管与第二外钢管焊接，连接处的空腔内填充胶结材料。本发明的钢管混凝土柱对接连接节点采用钢筋笼和波纹管浆锚连接，可简化工艺、降低成本，有效提升施工效率，可广泛的应用在装配式结构体系中。
