Prefabricated braced steel frame column end splicing joint structure

Abstract

The invention provides a prefabricated braced steel frame column end splicing joint structure. The prefabricated braced steel frame column end splicing joint structure is located between two prefabricated braced steel frames. The braced steel frame I is located below the joint, and the braced steel frame II is located above the joint. Each braced steel frame is composed of H-shaped columns, H-shaped beams and supports. According to the braced steel frame I, end plates are welded to the tops of the H-shaped columns, stiffening ribs are arranged at the joints of the H-shaped columns and the H-shaped beams, horizontal stiffening ribs are welded to the H-shaped columns, vertical stiffening ribs are arranged between the end plates of the H-shaped columns and the horizontal stiffening ribs of the H-shaped columns, stiffening ribs are welded to the H-shaped beams, and bolt holes are formed in upper flanges of the H-shaped beams. According to the braced steel frame II, end plates are welded to the bottoms of the H-shaped columns, H-shaped joggle beams are welded to the bottoms of the H-shaped columns, stiffening ribs are welded to the H-shaped joggle beams, bolt holes are formed in lower flanges of the H-shaped joggle beams, stiffening ribs are arranged at the joints of the H-shaped columns and the H-shaped joggle beams, horizontal stiffening ribs are welded to the H-shaped columns, and vertical stiffening ribs are arranged between the end plates of the H-shaped columns and the horizontal stiffening ribs of the H-shaped columns.

Description

technical field [0001] The invention belongs to the technical field of steel structure construction of prefabricated buildings, in particular to a spliced ​​joint structure at the end of a supporting steel frame column Background technique [0002] The construction industry is an important material production sector of the national economy, and has a close relationship with the development of the entire country's economy and the improvement of people's lives. In recent years, with the continuous deepening of the reform of the construction industry, the construction industry has continued to develop rapidly, the material and technological foundation has been significantly enhanced, the demographic dividend has gradually disappeared, and the requirements for energy conservation and environmental protection have become higher and higher. The on-site construction production method based on low labor prices is becoming increasingly challenged. The prefabricated building has fast...

AI Technical Summary

Problems solved by technology

Among them, welded joints save more materials under the premise of ensuring safety, but the on-site construction workload is large, which does not meet the development needs of industrialized buildings; the connection of spliced ​​plates will affect the connection between the supporting steel frame and the surrounding beams; The internal force is relatively large, and only the existing end plate connection cannot meet the bearing capacity requirements

Therefore, the existing splicing node form cannot meet the requirements
