Assembled-type beam-column joint connecting structure

Abstract

The invention discloses an assembled-type beam-column joint connecting structure. The assembled-type beam-column joint connecting structure comprises a chord member frame, wherein the chord member frame comprises two chord members (1) which are arranged in parallel, a sleeve (7) which is welded between the chord members (1), and an upper column (6) and a lower column (8) which are fit with the sleeve (7) in an insertion manner; the two parallel chord members are connected through truss web members (2) to form an integral body, the sleeve (7) is a rectangular parallelepiped structure with two open ends on the whole, and a sleeve upper flange (5) and a sleeve lower flange (9) are respectively welded on the edges of the open ends of the sleeve (7). The assembled-type beam-column joint connecting structure has the advantages of light entire structure weight, energy saving, environmental friendliness, fast construction speed, high industrialization level and the like, can effectively solve various problems that the building industrialization level in China is low, the building construction labor productivity is low, the quality of traditional building products is low and the like, and adapts to the development of the building industry in China.

Description

technical field [0001] The invention relates to the field of steel structures, in particular to an assembled beam-column joint connection structure. Background technique [0002] In the traditional fully welded beam-column joints, the lower flange of the beam and the web are welded to the column on site. Although this connection is a rigid connection, the ductility of the joint is poor, and brittle failures are prone to occur in earthquakes, and on-site welding is required, which greatly affects the construction. The speed and quality are not suitable for fabricated steel structures. At the same time, due to the large welding area, it is easy to generate large residual stress, which affects the mechanical performance of the joints. [0003] In traditional beam-column joints connected by high-strength bolts, the beam end seal plate and box-shaped columns are fastened and connected by high-strength bolts. When fastening, workers need to put their hands into the box-shaped colu...

AI Technical Summary

Problems solved by technology

[0002] In the traditional fully welded beam-column joints, the lower flange of the beam and the web are welded to the column on site. Although this type of connection is a rigid connection, the ductility of the joints is poor, and brittle failures are prone to occur in earthquakes, and on-site welding is required, which greatly affects the construction. Speed ​​and quality are not suitable for fabricated steel structures. At the same time, due to the large welding area, it is easy to generate large residual stress, which affects the mechanical performance of nodes

[0003] In traditional beam-column joints connected by high-strength bolts, the beam end seal plate and box-shaped columns are fastened and connected by high-strength bolts. When fastening, workers need to reach into the box-shaped columns. It is inconvenient, and the bolt holes will weaken the short column of the node, affecting its mechanical performance

[0004] In the traditional bolted and welded joint connection, the upper and lower flanges of the beam and column are welded to the column on site, and the web at the beam end is bolted to the column through a shear plate. This connection method requires on-site welding, which greatly affects the construction speed and quality. The program is complex and it is not easy to achieve rigid connection
