Embodiment 1

[0047] Combined with the manual figure 1 to attach Figure 8 , to describe the structure, construction and implementation process of this embodiment in detail. The steel column 100 is preferably a steel column with a rectangular or square section in this embodiment, Figure 5 The one in the figure is a square steel pipe column, which is used as a steel column.

[0048] The steel beam 200 is an I-shaped structure composed of a web and a flange. The two ends of the steel beam 200 are symmetrically provided with connecting parts 210 for connecting with two different steel columns. The connecting part of this embodiment passes through Formed by special design, having a specific structure and construction.

[0049] Correspondingly, a steel beam fixed support is provided on the steel column, and the support also has a specific structure and structure, and the connection between the support and the steel beam is connected by plugging and bolting. The connection structure has a p...

Embodiment 2

[0077] refer to Figure 9 In this embodiment, a connecting plate 214 is welded between the plug-in plates at the end of the steel beam to connect the two plug-in plates into one body to improve the local rigidity.

Abstract

The invention discloses a steel structure beam column connection node and a connection method thereof in order to solve the problem that an existing connection node is prone to brittle fracture. The steel structure beam column connection node is used for connection between a steel column and I-shaped steel beams. The steel beams and the steel column are connected through a corbel. The corbel is anenclosing structure formed by welding a plurality of modules of the same structure to the steel column. Each module is of a Y-shaped structure composed of two fixed plates and a steel wing plate, wherein a plug space is formed between the two opposite steel wing plates. Each connecting part comprises at least one plug plate welded to the end of one steel beam. The plug plates are plugged into theplug spaces. The steel wing plates and the plug plates are connected through mounting holes and high-strength bolt assemblies. The steel beams and the corbel are preliminarily positioned in a plug-inmode and are in rigid connection or semi-rigid connection through high-strength connecting assemblies. The steel structure beam column connection node is easy to assemble and capable of realizing full-assembly installation.

Description

technical field [0001] The invention relates to the technical field of beam and column installation of fabricated steel structures. Background technique [0002] In the field of prefabricated steel structure technology, steel structure nodes need to be connected by prefabricated connection. The traditional connection method refers to Figure 10 The structure shown in , that is, an extended corbel is welded on the steel beam, and then the steel plate and other connecting pieces are used for transition connection between the corbel and the steel column, and high-strength bolts are used to connect the web of the I-beam and the Flanges are reinforced. The main problem with this structure is that the seismic performance is poor, and when a strong earthquake occurs, brittle fractures are likely to occur at the corbels or connecting bolts. [0003] In order to solve the seismic problem of the joints of steel beams and steel columns, experts and scholars at home and abroad have con...
