Problems solved by technology

For beam-column joints with weak axis connections, at present, additional ribs or connecting plates are usually welded on the H-shaped steel columns, and then connected to the H-shaped steel beams through welds or bolts. It is difficult to guarantee the quality of beam-column joints and the progress of construction and installation
In addition, the weak-axis connection of the beam-column joint has more structural settings than the strong-axis connection, and the force transmission and deformation are more complicated, which is difficult in analysis, design and installation
In addition, there have been few researches on H-shaped steel column weak axis connection at home and abroad, and there are few joint forms actually put into use.

Embodiment 1

[0027] This embodiment is a rigid node connected by a weak shaft of steel structure H-shaped steel of the present invention, as attached Figure 1-4 As shown, it includes an H-shaped steel column 1 , a square steel pipe sleeve connector 3 fixed in the H-shaped steel column 1 , and an H-shaped steel beam 2 fixed on the square steel pipe sleeve connector 3 . Considering the difficulty of on-site welding and installation, the square steel pipe sleeve connector 3 is applied to the H-shaped steel beam-column weak-axis joints, and reinforcement measures are taken for the joints to form a clear force transmission, high bearing capacity, and free site. Suitable for welding and easy installation, the weak shaft connection of the square steel pipe sleeve connects the beam-column joints of the steel structure.

[0028] The square steel pipe sleeve connector 3 includes a square steel pipe 6 , bolt holes 7 are provided on the web and flange of the H-shaped steel column 1 , and bolt holes 7...

Embodiment 2

[0038] This embodiment is a hinge node connected by a weak axis, as shown in the attached Figure 5 , 6 As shown, on the basis of Embodiment 1, the bottom plate and triangular rib plate of the square steel pipe sleeve connector 3 are removed, and the baffle plate 5 and the grouting material are not provided, and the end face of the H-shaped steel beam 2 and the web of the H-shaped steel column 1 There is a certain distance between the boards.

[0039] The installation method of this embodiment is:

[0040] Step 1: Connect the web plate of the H-shaped steel column with the inner plate of the square steel pipe of the square steel pipe sleeve connector through high-strength bolts, and pass the flange of the H-shaped steel column with the square steel pipe left and right sides of the square steel pipe sleeve connector. High-strength bolt-to-hole connection.

[0041] Step 2: Insert the H-shaped steel beam into the square steel pipe of the square steel pipe sleeve connector, and...

Abstract

The invention relates to a beam-column joint of a square steel pipe sleeve weak shaft connection steel structure and an installation method of the beam-column joint. The beam-column joint comprises anH-shaped steel column, a square steel pipe sleeve connecting piece and an H-shaped steel beam. The square steel pipe sleeve connecting piece is fixedly arranged in the H-shaped steel column, and theH-shaped steel beam is fixed to the square steel pipe sleeve connecting piece. Bolt holes which are corresponding in position are formed in the connection portions of the H-shaped steel column and thesquare steel pipe sleeve connecting piece and the connection portions of the square steel pipe sleeve connecting piece and the H-shaped steel beam, and are connected through high-strength bolts. TheH-shaped steel beam-column joint adopts the square steel pipe sleeve connecting piece, the force borne by the H-shaped steel beam transmits to the H-shaped steel column through the square steel pipe sleeve connecting piece, and the force transmission is clear and easy. The square steel pipe sleeve connecting piece comprises a long base plate, accessory rib plates and a closed space through the design, the closed space is defined by baffles, grouting materials can be poured into the closed space, and therefore the rigidity and the bearing capacity of the joint are advantageously guaranteed by the measures.

Description

technical field [0001] The invention belongs to the technical field of construction engineering steel structures, in particular to a steel structure beam-column node connected by a square steel pipe sleeve with a weak shaft and an installation method thereof. Background technique [0002] The beam-column joint is one of the important components of the steel frame structure. In the steel structure system where the beam-column adopts H-shaped steel, there are generally two connection methods, the strong-axis connection and the weak-axis connection. For beam-column joints with weak axis connections, at present, additional ribs or connecting plates are usually welded on the H-shaped steel columns, and then connected to the H-shaped steel beams through welds or bolts. It is difficult to guarantee the quality of beam-column joints and the progress of construction and installation. In addition, the weak-axis connection of beam-column joints has more structural settings than the st...
