A steel structure node and its assembly method

Abstract

The invention provides a steel structure node and an assembly method thereof, belonging to the field of steel structures. It solves the problem that pipelines cannot be laid inside the existing steel structure nodes and the strength is low. The steel structure node is used to connect the column and the beam. The node includes a vertical connector and four horizontal connectors; the vertical connector includes four vertical connecting pipes whose cross-section is isosceles trapezoidal The outer plate, the vertical inner plate and two vertical side plates form a vertical grouting area in the vertical connecting pipe, the four vertical connecting pipes are closely fixed through the vertical side plate, and the four vertical inner plates are enclosed to form a vertical threading hole; the horizontal connecting parts include It is two horizontal connecting pipes and one internal strengthening pipe of rectangular pipe structure. A horizontal grouting area is formed in the horizontal connecting pipe, and a horizontal line hole is formed in the internal strengthening pipe; The cross beam is sleeved on the outer end of the cross connector. The external strength of this node is higher, and the internal wiring is convenient.

Description

technical field [0001] The invention belongs to the technical field of steel structures, and relates to a steel structure node and an assembly method thereof. Background technique [0002] Steel structures are widely used in existing buildings, and nodes are used to fix beams and columns in steel structures, so as to realize prefabricated connections. For example, the application number is 201710035802.X, and the Chinese invention patent titled "a double-column and double-beam connection device for fabricated steel structure" prefabricates the components in the factory, and then assembles and welds them on site to achieve The installation is convenient and fast, and the construction efficiency is high. But it has the following problems: [0003] 1. Concrete needs to be poured in the short column, so that the water, electricity and heating pipelines laid in the main beam and the secondary beam cannot pass through the short column. Therefore, it is necessary to lay open wire...

AI Technical Summary

Problems solved by technology

[0003] 1. Concrete needs to be poured in the short column, so that the water, electricity and heating pipelines laid in the main beam and the secondary beam cannot pass through the short column, so it is necessary to lay open wires, which is unsightly and has potential safety hazards

[0004] 2. Columns and beams are only fixed by plugging and welding, and only concrete is poured inside the column, so the joint strength of the column and beam is low
