Description

A new type of assembled beam-column joint connection structure

technical field

The invention relates to the field of steel structures, in particular to a novel assembled beam-column joint connection structure.

Background technique

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.

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 columns. It is inconvenient to come, and at the same time, the bolt holes will weaken the short column of the node, affecting its mechanical performance.

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 complicated and it is not easy to realize rigid connection.

Contents of the invention

The invention proposes a new type of assembled beam-column joint connection structure, the purpose of which is to overcome the defects of the prior art, meet the mechanical properties of the joints, realize the rigid connection of beam-column joints, realize the assembly of structures, and improve the assembly of components The speed fully adapts to the requirements and characteristics of the fabricated steel structure system.

In order to solve the existing problems in the background technology, it comprises a crossbeam, a sleeve 9 arranged between the crossbeams and a lower column 16 which is plugged and fitted with the sleeve 9 and the upper column 15 respectively; the crossbeam consists of two parallel Composed of angle steel beams 1, two adjacent angle steel beams 1 are welded into a whole through angle steel beam connecting plates 2, and the sleeve 9 as a whole is a cuboid structure with openings at both ends, and the edges of the opening ends are welded respectively There are sleeve upper flange 4 and sleeve lower flange 6. The upper part of the lower column 16 is welded with two lower column end plates 10 that are plugged and fitted with the sleeve 9. The other end of the lower column end plate 10 is worn through Extend through the sleeve 9 into the upper column 15, and be screwed and fixed into one body by bolts.

The bottom of the upper column 15 is welded with an upper column flange 3 docked with the sleeve upper flange 4 , and the periphery of the upper column flange 3 is provided with a threaded hole.

Near the root of the lower column end plate 10 is welded a lower column flange 7 docked with the sleeve lower flange 6 , and the periphery of the lower column flange 7 is provided with a threaded hole.

Due to the adoption of the above technical solutions, the present invention has the following beneficial effects: the whole structure is light in weight, energy-saving and environmentally friendly, fast in construction speed, and high in industrialization, and can effectively solve the problems of low construction industrialization level in my country, low labor productivity in house construction and the quality of traditional house products. Low and many other problems, adapt to the development of my country's construction industry.
