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

Embodiment 1

[0016] see Figure 1-3 , it includes a chord frame, and the chord frame includes a beam, a sleeve 9 arranged between the beams, an upper column 15, and a lower column 16 that is plugged with the sleeve 9 and the upper column 15 respectively; The crossbeam is composed of two parallel angle steel crossbeams 1, and the two adjacent angle steel crossbeams 1 are welded into a whole through the angle steel crossbeam connecting plate 2, and the sleeve 9 is a cuboid structure with openings at both ends as a whole. A sleeve upper flange 4 and a sleeve lower flange 6 are respectively welded on the edge of the opening end, and 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 plate 10 extends into the upper column 15 through the sleeve 9, and is screwed and fixed as a whole by bolts.

[0017] The bottom of the upper column 15 is welded with an upper column flange 3 docked with the sleev...

Embodiment 2

[0021] According to the structure disclosed in Embodiment 1, the chord frame, the upper column 6 and the lower column 8 are pre-processed in the factory. When transported to the construction site in the later stage, only the butt joint assembly operation is required. There is no welding operation requirement on site, and the bolts The layout is also easy to operate manually, which greatly improves the assembly speed and quality.

Abstract

The invention discloses an assembled beam-column joint connection structure, which comprises beams, sleeves (9) arranged between the beams, upper columns (15) and sleeves (9) and upper columns (15) inserted respectively. The lower column (16) that connects fit; Described beam is made up of two parallel angle steel beams (1), is welded into a whole by angle steel beam connecting plate (2) between two adjacent angle steel beams (1), The sleeve (9) as a whole is a cuboid structure with openings at both ends, and the upper flange (4) and the lower flange (6) of the sleeve are respectively welded on the edge of the opening. The whole structure of the present invention is light in weight, energy-saving and environment-friendly, fast in construction speed and high in industrialization degree, etc., and can effectively solve many problems such as low level of construction industrialization in my country, low labor productivity in house construction and low quality of traditional house products, and adapts to the development of my country's construction industry.

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...
