Profile steel splicing, machining and welding process

Abstract

The invention relates to a profile steel splicing, machining and welding process. The profile steel splicing, machining and welding process adopts a base plate, an inner supporting device and outer supporting devices; the inner supporting device is installed at the middle part of the upper end of the base plate; the outer supporting devices are uniformly arranged at the outer side of the base plate; and the outer supporting devices are installed at the upper end of the base plate. The profile steel splicing, machining and welding process can solve the problems that the existing equipment is poor in positioning effect on profile steel before the profile steel is welded and cannot realize accurate clamping and positioning on the profile steel, the profile steel is easily deviated in a welding process, thus a steel structure is poor in welding effect and low in accuracy and can be easily scrapped; when the existing equipment is used for clamping the profile steel, the clamping effect is poor, a clearance between the profile steel cannot be accurately regulated, so the welded profile steel is low in rigidity and poor in stability; subsequent machining of the steel structure is affectedand the like.

Description

technical field [0001] The invention relates to the field of section steel splicing processing welding, in particular to a section steel splicing processing welding process. Background technique [0002] At present, some large-scale public buildings such as halls and workshops with large spans are basically steel structure buildings. Steel structure buildings have strong and durable structures, rapid construction, easy reconstruction, and easy demolition. They are the first choice for residential buildings and structural development. important trends. With the rapid growth of my country's steel output and the development and application of new building materials, the steel structure residential system that meets the above needs has gradually developed and attracted widespread attention. When splicing steel structures, they are usually connected by welding. [0003] At present, the existing steel structures usually have the following defects during welding processing: 1. Be...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that the existing equipment has poor positioning effect of the profiled steel before welding the profiled steel, and cannot accurately clamp and position the profiled steel, which causes the profiled steel to easily shift during the welding process, making the welding effect of the steel structure poor, The accuracy is low, which will easily lead to the scrapping of the steel structure. Moreover, when the existing equipment clamps the steel, the clamping effect is poor, and the gap between the steel cannot be adjusted accurately, resulting in low rigidity of the steel after welding. Poor stability, affecting the subsequent processing and use of steel structures and other problems
