Square steel tube column-H-shaped steel beam end-plate connecting node

Abstract

The invention discloses a square steel tube column-H-shaped steel beam end-plate connecting node which comprises a square steel tube column, an H-shaped steel beam, a node end plate, a beam end plate and side steel plates; the beam end plate is in weld connection with the end part of the H-shaped steel beam, and a bolt hole is formed in the beam end plate; the two side steel plates are in weld connection with wall plates on the two sides of the square steel tube column; the node end plate is in weld connection with each of the two side steel plates, and a screw hole corresponding to the beam end plate is formed in the node end plate; the square steel tube column and the H-shaped steel beam are connected into a whole through friction type high-strength bolts by means of the node end plate and the beam end plate. The square steel tube column-H-shaped steel beam end-plate connecting node disclosed by the invention is simple in structure and solves the construction problem caused as a partition plate is welded in the square steel tube, and meanwhile, the pouring of concrete in the steel tube is not affected; an anti-seismic design principle of 'strong node and weak component' is easy to realize, and the anti-seismic property is better; the construction efficiency is higher, and the suitability for the construction of the square steel tube column-steel beam connecting node in a multi-rise or high-rise building steel structure is realized.

Description

technical field [0001] The invention relates to a connection node between a steel structure beam and a column in the construction field, in particular to a connection node suitable for a square steel pipe column-H-shaped steel beam in a multi-storey or high-rise building steel structure. Background technique [0002] At present, there are three main ways to connect square steel pipe columns and steel beams: inner diaphragm type, diaphragm through type and outer diaphragm type. For inner diaphragm joints, the last weld of the inner diaphragm is welded in a closed column, which needs to be completed by electroslag welding. The construction is complicated and the cost is high. The size of the hole is affected by the size of the section, and the pouring of concrete in the steel pipe brings difficulties. The clapboard through joint needs to disconnect the steel pipe column at the joint, the structure is complex, the welding workload is large, and there are concrete pouring probl...

AI Technical Summary

Problems solved by technology

For inner diaphragm joints, the last welding seam of the inner diaphragm is welded in a closed column, which needs to be completed by electroslag welding. The construction is complicated and the cost is high. At the same time, if holes are opened on the diaphragm to pour concrete, the The size of the hole is affected by the size of the section, and the pouring of concrete in the steel pipe is difficult

The clapboard through joint needs to disconnect the steel pipe column at the joint, the structure is complex, the welding workload is large, and there are concrete pouring problems like the inner clapboard joint

The construction of the outer diaphragm joint is simple and not limited by the section size of the steel pipe, but the amount of steel used is relatively large, and the outer diaphragm makes the corner of the joint protrude, which affects the appearance of the building
