Casing structure preventing electric welding slag from overflow and processing method of casing structure

Abstract

The invention discloses a casing structure preventing electric welding slag from overflow. The structure comprises upper and lower cover plates arranged in parallel, two web plates are arranged in parallel between the upper and lower cover plates, support rods and internal separator plates are arranged between the two web plates, an included angle is formed between each support rod and each web plate, positions where each web plate makes contact with the upper and lower cover plates are provided with electric welding slag liner plates respectively, and each electric welding slag liner plate clings the inner side surfaces of the upper and lower covers plates and the corresponding web plate. The invention also discloses a processing method of the casing structure. Via the processing method,the size precision of the casing type separator plates and web plates is improved, the processing difficulty is reduced, the electric welding slag liner plates need no machining, the processing cost is reduced, the clinging degree between the electric welding slag liner plates and the upper and lower cover plates is detected in a visualized way, and the electric welding slag is prevented from overflow.

Description

technical field [0001] The invention belongs to the technical field of production of steel structure box-shaped products, and in particular relates to a box-shaped structure for preventing overflow of electric welding slag, and also relates to a processing method of the box-shaped structure. Background technique [0002] The welding of box-shaped column partitions is difficult, and electroslag welding partitions require full penetration, which is not easy to control; there are usually two methods for box-shaped inner partitions: the first method is to assemble the lining strips of the inner partitions on the tooling platform, and the lining strips It needs to be machined, and the dimensional accuracy of the inner partition is extremely high, and the process is complicated. Finally, due to the deviation of the blanking size of the web and the assembly of the partition, the cover plate and the lining strip of the partition will appear to varying degrees when the box-type cover ...

Problems solved by technology

[0003] The purpose of the present invention is to provide a box-type structure for preventing the leakage of electric welding slag, which solves the problem that the welding slag in the existing box-type structure products is easy to overflow during welding

[0004] Another object of the present invention is to provide a method for processing an electric welding slag-proof box-shaped structure, which solves the problem that the internal partition liner and the box-shaped cover cannot be tightly closed due to the size deviation of the inner partition or the lack of precision in the existing method. posted questions
