Steel structure and construction method thereof

Abstract

The invention provides a steel structure and a construction method thereof, belonging to the technical field of steel structure buildings. A steel structure comprises a first steel column, a second steel column and a sleeve, the sleeve is a hollow structure opening at two ends, the first steel column and the second steel column are respectively inserted in the opening at two ends of the sleeve, awall of the sleeve is provided with a plurality of through holes, the first steel column and the second steel column are respectively welded and fixed at the sleeve through the through holes, edges ofthe openings at two ends of the sleeve respectively form a welded layer with an external wall of the first steel column and the external wall of the second steel column. A steel structure construction method is applied to the steel structure. With the steel structure and the construction method provided by the invention, work procedures before welding of the steel columns can be reduced, and difficulty in welding between the steel columns also can be reduced.

Description

technical field [0001] The invention relates to the technical field of steel structure buildings, in particular to a steel structure and a construction method thereof. Background technique [0002] Steel structure building is a new type of building system, which breaks through the industry boundaries among the real estate industry, construction industry, and metallurgy industry, and integrates into a new industrial system. Compared with traditional concrete buildings, steel structure buildings use steel structures Instead of reinforced concrete, it has higher strength and better earthquake resistance. [0003] A steel structure is a structure composed of multiple steel frames, and the steel frame is composed of multiple steel columns. Studies have shown that in some earthquake disasters, the damage of steel structures mostly occurs at the joints of steel frames, so the design of steel frame joints is very important. [0004] In the prior art, the steel columns constituting...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the steel columns constituting the steel frame are usually rolled into steel plates in the steel mill, and then the steel plates are transported to the processing plant for gas cutting, bevel processing, correction, etc. to complete the processing of the steel columns. The processed steel columns are processed by box type correction, steel column end face milling, shot blasting, coating and other processes for welding. Finally, the steel columns processed by the above processes are transported to the construction site for steel frame assembly. The adjacent steel frames in the steel frame The columns are directly welded and fixed to each other, which is difficult to weld, and there are many processing steps required before welding the steel columns
