Prefabricated supporting steel frame column end splicing node structure

Abstract

The present invention provides an assembled support steel frame column end splicing node structure, the assembled support steel frame column end splicing node structure is located between two assembled support steel frames, the support steel frame I is located at the lower part of the node, and the support steel frame II is located at upper part of the node. The supporting steel frame consists of H-columns, H-beams and braces. The supporting steel frame I welds the end plate on the top of the H-shaped column, sets the stiffener at the joint between the H-shaped column and the H-shaped beam, welds the horizontal stiffener on the H-shaped column, and sets the horizontal stiffener between the H-shaped column end plate and the H-shaped column Vertical stiffeners, welded stiffeners on the H-shaped beam, and bolt holes on the upper flange of the H-shaped beam. The supporting steel frame II welds the end plate at the bottom of the H-shaped column, welds the H-shaped spliced ​​beam at the bottom of the H-shaped column, welds the stiffener on the H-shaped spliced ​​beam, opens bolt holes on the lower flange of the H-shaped spliced ​​beam, and splices the H-shaped column and the H-shaped Stiffeners are set at the beam joints, horizontal stiffeners are welded on the H-shaped columns, and vertical stiffeners are set between the end plates of the H-shaped columns and the horizontal stiffeners 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
