Method for producing box beam/column with steel structure

Abstract

The invention relates to a method for producing a box beam / column with a steel structure, comprising the following steps: (1) numerically controlling web plates, blanking based on the size of a partition plate and processing to form a bevel outlet; (2) assembling spot welding lining plates on the backs of the web plates and the partition plate; (3) assembling cover plates and two of the web plates to form a U-shape groove on a box assembling machine; (4) placing the partition plate in the formed U-shaped groove and welding three sides of the partition plate; and (5) assembling the cover plates and welding attachment welds between every two cover plates. The method solves the problem that the box beam / column cannot produce when no special electroslag welding equipment is provided, what is more important, the method solves the problem that welding is difficult by adopting the electroslag welding when the thickness of a wall panel of the beam / column is below 18 mm during multi-layer buildings are built. By adopting the method, the processing process is simplified, the component quality and the manufacture efficiency are greatly improved, favorable economic and societal values are achieved, and polarization and application are easy.

Description

technical field [0001] The invention relates to a method for manufacturing a steel structure box beam / column, belonging to the technical field of steel structure manufacture. Background technique [0002] As we all know, the existing steel structure box girder / column is composed of two cover plates and two web plates, and the four main welds at the junction of the four plates are designed to be full penetration grooves (CP) in sections according to the strength requirements. and partial penetration groove (PP). Among them, the steel structure box girder / column is equipped with a diaphragm, the main diaphragm and the web adopt full penetration welding, and the ordinary diaphragm and the cover web welded on three sides. [0003] At present, the manufacturing process of steel structure box girders / columns is roughly as follows: Firstly, the column plate is cut with a CNC flame cutting machine, the cover plate, web plate, partition plate and baffle plate are cut, and the web pl...

AI Technical Summary

Problems solved by technology

Since electroslag welding needs to be surrounded by two baffles, partitions and the four side walls of the box-shaped beam / column to form a sleeve shape, and the clearance requirements for the sleeve are very strict, and two thicker baffles are required , also requires low production efficiency and expensive electroslag welding equipment and special nozzles, which is easy to delay the construction period, not only increases the manufacturing cost of the product, but also is difficult, making the production efficiency low

In addition, when the thickness of the wall plate of the beam and column is below 18mm, it is not easy to weld with the current electroslag welding
