Connecting node of square steel pipe column and H-shaped steel beams

Abstract

The invention relates to a connecting node of a beam and a column of building steel structures, in particular to a connecting node of a square steel pipe column and H-shaped steel beams for multi-layer and high-rise steel structures. The connecting node comprises a square steel pipe column, H-shaped steel beams and T-shaped steels; the T-shaped steels are arranged on the lateral wall of the square steel pipe column and the upper and lower wing edges of the H-shaped steels; webs of the T-shaped steels are connected with the wing edges of the H-shaped steel beams; and the wing edges of the T-shaped steels are fixedly connected with the lateral walls of the square steel pipe column. According to the connecting node of the square steel pipe column and the H-shaped steel beams, the connecting node is simple in structure, and the problem of construction difficulty in installing an internal separating plate is solved; a plastic hinge shifts outwards and better shock-absorbing property is achieved; the construction of an upper floor and the casting of concrete in the square steel pipe are not influenced; and the steel consumption is low. Therefore, the connecting node has high economic and social benefits.

Description

technical field [0001] The invention relates to a connection node between a beam and a column of a building steel structure, in particular to a connection node suitable for a square steel pipe column-H-shaped steel beam in a multi-layer and high-rise steel structure. It belongs to the technical field of multi-storey and high-rise buildings. Background technique [0002] At present, most of the connection nodes between square steel pipe columns and H-shaped steel beams in my country increase the joint stiffness by setting inner diaphragms. Its main forms are: inner partition type, partition through type and outer partition type. Among them, the inner diaphragm type is suitable for square steel pipe columns with larger cross-sections, but it is difficult to realize the square steel pipe columns with smaller cross-sections due to the limitation of welding space, and the existence of inner diaphragms affects concrete pouring. The through-type joint of the diaphragm requires t...
