Fabricated square steel tube confined concrete column beam joint
The invention discloses a fabricated square steel tube confined concrete column-beam joint which comprises a joint upper column steel tube, a middle connecting steel tube, a joint lower column steel tube and a side structural beam. The node upper column steel pipe, the middle connecting steel pipe and the node lower column steel pipe are aligned up and down; the structural beam is arranged on the outer side of the middle connecting steel pipe in the circumferential direction, longitudinal bars of the structural beam horizontally stretch into the upper and lower column steel pipes through the first notches and the second notches, and the upper and lower column steel pipes, the middle connecting steel pipe and the structural beam are poured into a whole through concrete. The node has the beneficial effects that the upper and lower column steel pipes of the node are connected with the middle connecting steel pipe and are connected with the structural beams on the side parts through the horizontal connecting partition plates, and the longitudinal bars of the structural beams extend into the square steel pipes, so that the node form is convenient to construct, simple and clear in force transfer path, high in node rigidity, high in bearing capacity and capable of greatly improving the shear capacity; and meanwhile, the problems that stirrups are too large due to the shear resistance problem, and construction of a joint area is inconvenient are solved.
本发明公开了一种装配式方钢管约束混凝土柱梁节点，包括节点上柱钢管、中部连接钢管、节点下柱钢管和侧部的结构梁；所述节点上柱钢管、中部连接钢管和节点下柱钢管上下对正；所述结构梁周向布置在中部连接钢管的外侧，结构梁的纵筋经第一槽口和第二槽口水平伸入上下柱钢管内部，节点上下柱钢管、中部连接钢管和结构梁通过混凝土浇筑于一体。本发明的有益效果为：节点上下柱钢管与中部连接钢管相连，并通过水平连接隔板与侧部的结构梁相连，结构梁的纵筋伸入方钢管内部，这种节点形式施工方便，传力路径简洁明确，节点刚度大，承载力高，抗剪能力大大提升，同时解决了因抗剪问题导致的箍筋过大，节点区施工不便的问题。
