Steel structure space connecting joint structure

Abstract

The invention provides a steel structure space connecting joint structure. The steel structure space connecting joint structure comprises a joint core area structure and connected rod pieces, and a plurality of connecting lug plates are distributed on the periphery of the joint core area structure and used for connecting the connected rod pieces in different directions. The connecting lug plates are provided with at least one pin shaft or bolt connecting hole and is rigidly connected with the joint core area structure. U-shaped inserting openings are formed in the end parts of the connected rod pieces and matched with the connecting lug plates in a butt joint mode, and the U-shaped inserting openings and the connecting lug plates are connected in a hinged mode through the pin shafts or thebolts. The standard connection problem of multi-directional crossed rod pieces can be effectively solved, joint connection is safe, convenient and efficient, all assemblies can be repeatedly disassembled, assembled and used, and a standard, economical and reasonable solution path is provided for steel structure house space connection.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a space connection node structure of a steel structure. Background technique [0002] Steel structure housing is a residential building with steel as the load-bearing beam and column of the building. It has many advantages such as light weight, high strength, safety and reliability, good earthquake resistance and wind resistance. [0003] In the prior art, there will be a problem of standard connection of multi-directional cross members at the truss nodes of the steel structure building. In the prior art, the multi-directional cross members are avoided by arranging the members vertically and horizontally, so as to avoid the problem of the connection of standard members. question. [0004] However, the truss node structure used in the steel structure houses in the prior art has many construction procedures, and the construction process is very cumbersome, and it is ...

AI Technical Summary

Problems solved by technology

[0004] However, the truss node structure used in the steel structure houses in the prior art has many construction procedures, and the construction process is very cumbersome, and it is difficult to be disassembled and used repeatedly. Hollow welded ball joints, which weld the main pipes, branch pipes and reinforcement plates in different directions through hemispheres, so that the joints can withstand greater horizontal shear force and reduce the additional bending moment generated by the horizontal force, but its construction process is complicated and requires On-site welding, and repeated disassembly and assembly cannot be realized
