A low-level multi-storey assembled beam-column joint

Abstract

A low-level prefabricated beam-column splicing joint, including steel columns, steel beams, web connection components and cover plates; a through hole is provided at the center of the cover plates, two cover plates are fixedly sleeved on the steel columns, and two A number of steel beams are fixedly arranged between the cover plates, and the angle between adjacent steel beams is 90° or 180°; the end of the steel beams near the steel column is provided with a web connection assembly. The invention simplifies the difficulty of on-site construction operations, improves the assembly of buildings and the aesthetics of components, and reduces the influence of bearing capacity drop caused by construction errors. In this way, the nodes are connected reliably, the force transmission path is clear, and the welding volume is small, which effectively avoids the defects of cracks, pores, slag inclusions, incomplete penetration, and incomplete penetration during the welding process.

Description

technical field [0001] The invention belongs to the technical field of beam-column joints, in particular to a low-layer assembled beam-column joint. Background technique [0002] The low-level prefabricated steel structure is spliced ​​on-site by factory-processed modules. It has the advantages of rapid construction, reduced labor intensity, and reduced construction pollution. It is a green and environmentally friendly building and an innovative technology in the steel structure construction industry. [0003] Most of the beam-column joints are of the partition type, which requires the column to be divided into three sections and connected by partition welding. The welding volume of bulkhead joints is often relatively large, and the quality of on-site welding between steel beam ends and steel columns is difficult to guarantee. Moreover, the on-site welding takes a long time and the work efficiency is low. [0004] When the low-level prefabricated steel structure is install...

AI Technical Summary

Problems solved by technology

The welding volume of bulkhead joints is often relatively large, and the quality of on-site welding between steel beam ends and steel columns is difficult to guarantee

Moreover, on-site welding takes a long time and the work efficiency is low

[0004] When the low-level prefabricated steel structure is installed and constructed on site, due to the influence of construction errors, the ends of the steel beams cannot be accurately fitted with the inner partitions, resulting in an eccentric force on the steel beams, resulting in a loss of bearing capacity of the steel beams. reduce
