Assembly joints and construction methods of double-ear plate square pipe column and h-shaped steel frame with variable beam height

Abstract

A double-ear plate-type square steel pipe and H-shaped steel beam variable beam height assembled joint and its construction method, which relate to an assembled frame steel structure, including a square steel pipe section in the joint area, an H-shaped steel beam section in the joint area, and a connection The connectors include ear plates, end plates, and independently arranged upper and lower connectors, the ear plates are welded to square steel pipes, and the end plates are welded to H-beams; the upper and lower connectors are welded through high-strength The bolt connects the upper and lower flanges of the H-beam with the ear plate, and transmits the bending moment and shear force of the beam section to the ear plate to realize the reasonable stress of the structure. There is a long hole in the lower part of the ear plate, and the bolt can be adjusted The connecting height realizes the assembled connection of H-shaped steel beams with different heights. It has the advantages of zero welding on site, good component versatility, no damage to steel pipes, and reasonable force. It is suitable for the assembly of square steel pipe columns and H-shaped steel beam structures. connect.

Description

technical field [0001] The invention relates to a building steel structure node and a construction method thereof, and is characterized in that it is an assembled node of a square steel pipe column and an H-shaped steel beam in the steel structure and a construction method thereof. Background technique [0002] The prefabricated steel structure has become a hot spot in the development of the construction industry due to its advantages of light weight, high strength, good seismic performance, fast construction, short cycle, reusable use, and less pollution, especially the modular characteristics, which are more in line with my country's industrialization Development requirements, with good application prospects and market potential. The node is the most critical component of the fabricated steel structure. Its form and performance directly determine the industrialization degree and structural form of the structure. The square steel pipe column is the main vertical force member...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a square steel pipe column and frame H-shaped steel beam assembled joint with reasonable structure, convenient construction and stable performance and its construction method. The joint needs to ensure the overall rigidity and fast construction of the fully assembled joint. The problem of coordination and unification between the nodes, and the nodes are affected by the size limit of the components, so they can only be specially designed and manufactured, the universal type is poor, and it is difficult to achieve standardization, so the applicability and versatility of the nodes can be increased
