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 equipm

Embodiment Construction

[0022] Among them, the clapboard assembly is to add the liner to the clapboard after cutting the groove. figure 2 parts shown.

[0023] The web assembly is to add the liner to the web after cutting the groove. image 3 parts shown.

[0024] The segmental splicing of the cover plate is to disconnect the cover plate at 200mm from the first set of dividers when there is a certain distance between the divider group and the next set, so as to facilitate the welding of the divider. The joint processing such as Figure 4 shown.

[0025] The manufacturing method of steel structure box beam / column of the present invention is as Figure 5 As shown, its specific production process is as follows:

[0026] (1) Use the computer to control the size of the cover plate, web plate and its lining plate, partition plate and its lining plate for blanking, and at the same time make grooves on both sides of the web plate and four sides of the partition plate. center drilling;

[0027] (2) As...

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 platesto 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 platesand 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...
