The invention discloses a vertical connection joint of a prefabricated reinforced concrete column. The vertical connection joint comprises a prefabricated column and steel joints arranged at the two ends of the prefabricated column. The steel joint at the lower end of the upper prefabricated column is connected with the steel joint at the upper end of the lower prefabricated column through welding or bolts and flanges; the steel connector comprises a steel cylinder, a horizontal steel plate perpendicular to the side wall of the steel cylinder is welded to the interior of the steel cylinder, column longitudinal bar reserved holes corresponding to longitudinal bars of the prefabricated column are formed in the horizontal steel plate, and the longitudinal bars penetrate through the column longitudinal bar reserved holes to be anchored to the horizontal steel plate. Shear-resistant studs are arranged in the steel cylinders, one ends of the steel cylinders and the prefabricated columns are poured together in a factory, and grooves or flanges are arranged at the other ends of the steel cylinders and used for connection of steel joints between the upper prefabricated columns and the lower prefabricated columns. The invention has the characteristics of low cost, convenience in assembly, reliable connection performance and high construction efficiency.
本发明公开了一种预制钢筋混凝土柱的竖向连接节点，包括预制柱和设置在预制柱两端的钢接头；上预制柱下端的钢接头与下预制柱上端的钢接头通过焊接或者螺栓、法兰连接；钢接头包括钢筒，所述钢筒的内部焊接有垂直于钢筒侧壁的水平钢板，所述水平钢板上开设有与预制柱的纵筋对应的柱纵筋预留孔，所述纵筋穿过柱纵筋预留孔与水平钢板锚固；钢筒的内部设有抗剪栓钉，所述钢筒的一端在工厂与预制柱混凝土浇筑在一起，另一端设有坡口或者法兰，用于上预制柱和下预制柱间钢接头的连接。本发明具有成本低、拼装方便、连接性能可靠、施工效率高的特点。
