Embodiment Construction
[0018] Such as Figure 1-3 As shown, a square hollow interlayer concrete-filled steel pipe column is connected to a steel beam, including an end plate 3, an angle steel 4 and a high-strength bolt connection pair 6, and a square hollow interlayer concrete-filled steel pipe column includes an outer square steel pipe 1, an inner square steel pipe 2 and concrete 7 Concrete 7 is poured between the outer steel pipe 1 and the inner square steel pipe 2, the end of the steel beam 5 is vertically welded on the end plate 3, and the connection between the steel beam 5 and the end plate 3 is along the web of the steel beam 5 One piece of angle steel 4 is welded up and down in the direction of the plate, and the corresponding positions of the angle steel 4, end plate 3, outer steel pipe 1 and inner steel pipe 2 are all provided with through holes, and the end plate 3 is closely attached to the outer steel pipe 1. Above, the high-strength bolt connection pair 6 connects the angle steel 4, th...

The invention belongs to the technical field of joints of civil structures, and particularly relates to a square hollow sandwich concrete filled steel tubular column and steel beam connection joint and a construction method thereof. According to the technical scheme, the connection joint includes an end plate, angle steel and high-strength bolt connection pairs. A square hollow sandwich concrete filled steel tubular column includes an outer square steel tube, an inner square steel tube and concrete, concrete is poured between the outer square steel tube and the inner square steel tube, the endof a steel beam is vertically and fixedly connected with the end plate, the upper and lower portions of the connection portion of the steel beam and the end plate are each welded with one block of angle steel in the wed direction of the steel beam, the corresponding positions of the angle steel, the end plate, the outer square steel tube and the inner square steel tube are provided with through holes, the end plate is closely attached to the outer square steel tube, the high-strength bolt connection pairs are used for making the angle steel, the end plate, the outer square steel tube and theinner square steel tube connected together, and the steel beam is vertically installed on the outer square steel tube. The bending moment can be effectively transmitted, the purpose of strengthening the joints and weakening the steel beam is achieved, so that a plastic hinge is far away from the steel beam joint during the earthquake, and later repair is facilitated.
Description
technical field [0001] The invention belongs to the technical field of civil structure nodes, and in particular relates to a connection node between a square hollow interlayer concrete filled steel pipe column and a steel beam and a construction method thereof. Background technique [0002] Concrete-filled steel tube columns use the synergistic effect of steel tubes and concrete in the process of stress to improve the bearing capacity of the structure. In recent years, with the development of high-rise and super high-rise structures in cities, concrete-filled steel tube columns have gradually been applied to practical In engineering, the hollow interlayer concrete-filled steel tube column has been widely used in some projects in recent years. Compared with the solid steel tube concrete column, it has the advantages of light weight, high bending rigidity and good seismic performance. However, the design of beam-to-column joints of hollow interlayer concrete-filled steel tube ...
