Novel assembled type beam column joint connecting structure

Abstract

The invention discloses a novel assembled type beam column joint connecting structure which comprises beams, a sleeve (9) arranged between the beams and a lower column (16) matched with the sleeve (9) and an upper column (15) in an inserted mode. Each beam is composed of two parallel steel angle beams (1) and the adjacent steel angle beams (1) are welded into a whole through steel angle beam connecting boards (2). The whole sleeve (9) is of a cuboid structure with openings formed in the two ends and an upper sleeve flange (4) and a lower sleeve flange (6) are welded to the edges of the opening ends of the sleeve respectively. The whole novel assembled type beam column joint connecting structure is low in mass, capable of saving energy, environmentally friendly, high in construction speed, high in industrialization degree, suitable for the development of the building industry of China and capable of effectively solving multiple problems that the building industrialization level of China is low, the house building labor productivity is low, and traditional house products are low in quality.

Description

technical field [0001] The invention relates to the field of steel structures, in particular to a novel 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...

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
