Concrete-filled steel tube connecting structure and construction method thereof
The invention belongs to the technical field of civil engineering, and particularly discloses a concrete filled steel tube connecting structure. Comprising upper steel pipes, lower steel pipes and connecting pieces. The bottom of the upper steel pipe is welded with an upper bottom plate, and the top of the lower steel pipe is welded with a lower bottom plate. The connecting piece comprises a core tube, a rib cage, an ultra-high performance concrete strip and a positioning hoop framework used for connecting and positioning the upper steel pipe and the lower steel pipe in the construction stage, the two ends of the core tube penetrate through the upper bottom plate and the lower bottom plate correspondingly and then stretch into the upper steel pipe and the lower steel pipe, and the rib cage is bound and fixed to the core tube and connected with the positioning hoop framework. Micro-expansive concrete is poured in a connecting area between the upper steel pipe and the lower steel pipe to form a connecting column, and the rib material cage is wrapped by the connecting column. And after the positioning hoop framework on the periphery of the connecting column is removed, the outer wall of the connecting column is wrapped with the ultra-high performance concrete strip. The invention further discloses a construction method of the concrete filled steel tube connecting structure. The connecting area is seamless, and operation is convenient.
本发明属于土木工程技术领域，具体公开了一种钢管混凝土连接构造。包括上钢管、下钢管和连接件。上钢管的底端焊接上底板，下钢管的顶端焊接下底板。连接件包括核心筒、筋材笼、超高性能混凝土条带和用于在施工阶段连接定位上钢管和下钢管的定位环箍骨架，核心筒的两端分别穿过上底板和下底板后伸入上钢管和下钢管中，筋材笼绑扎固定在核心筒上并与定位环箍骨架连接。在上钢管与下钢管之间的连接区域浇筑微膨胀混凝土而形成连接柱，连接柱包裹筋材笼。拆除连接柱外围的定位环箍骨架后，将超高性能混凝土条带包裹在连接柱的外壁上。本发明还公开了一种钢管混凝土连接构造的施工方法。本发明的连接区域无缝隙且方便操作。
