Mortise and tenon joint and bolt hybrid assembling type steel structure beam-column joint

Abstract

The invention relates to a mortise and tenon joint and bolt hybrid assembling type steel structure beam-column joint which comprises a steel structure beam, a steel structure column and a beam-columnjoint body. The steel structure beam and the steel structure column are connected together through the beam-column joint. The beam-column joint comprises an embedment mortise arranged at the flange end of the beam, an embedment groove body fixedly formed in the surface of the steel structure column, a web connecting plate and an additional connecting plate. The embedment mortise and the embedmentgroove body are in mortise and tenon joint connection. The web connecting plate, a beam web and the additional connecting plate are fixedly connected together through bolts. The beam-column joint is reasonable in structure, definite in force transmission, simple in installation process, safe, reliable, free of welding on site, free of damage to paint coatings, free for paint supplementing on site,high in speed and capable of saving materials and labor cost, the beam-column rigid connection is realized, and the construction period can be shortened by 15-25% compared with a site welding steel structure beam-column joint; no outward-extending cantilever beam sections are arranged on the column, loading and transporting are facilitated, the transport cost can be reduced by 20-30%; the construction cost is lower after standardized production is adopted.

Description

technical field [0001] The invention relates to the field of processing, manufacturing and assembling of prefabricated building steel structures, in particular to a beam-column joint of a mortise-and-bolt mixed-assembled steel structure. Background technique [0002] In the past two years, the state and various provinces and cities have intensively issued relevant standards and incentive policies, requiring vigorous development of prefabricated buildings, especially steel structure buildings. The steel structure has light weight, excellent earthquake resistance and wind resistance; simple on-site assembly, fast construction speed, high degree of industrialization, and low overall cost. After the steel structure building has reached the end of its service life, the steel can be recycled, which is green and environmentally friendly, and is in line with the policy of sustainable development. [0003] There are traditionally three connection forms for beam-column rigid joints i...

Problems solved by technology

Although this joint can realize the rapid installation of the steel structure beam-column joint, it still needs to rely on the end plate of the beam to transmit the internal force of the beam, and there is a certain deformation at the end, which cannot realize the rigid connection of the beam-column, and the amount of steel used for the end plate is large; especially The self-locking unilateral bolt installation process is complicated and the price is high
