Abstract

The invention discloses a steel box beam and a steel box beam machining method. The steel box beam comprises a body, the body is provided with a trapezoidal cavity with the cross section wide in upper and narrow in lower, multiple partition boards are evenly distributed in the cavity in the extension direction of the body, the partition boards and the periphery of the cavity are in full welding connection, the partition boards achieve the supporting and reinforcing effect, the whole structure of the steel box beam is more compact and stable, in addition, when the steel box beam is machined, the manner of 180 turnover construction is adopted, the overhead welding line is changed into the flat welding line, the welding quality of the welding line is ensured, the reworking caused by quality is reduced, the construction proceed is quickened, and the construction cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of bridge and tunnel construction, and more specifically, the invention relates to a steel box girder and a steel box girder processing method. Background technique [0002] At present, the steel box girder structure has been widely used in the construction process. The design structure of the steel box girder is complex, and the quality requirements are very high. In the actual application process, there are often problems of rework due to unqualified steel box girder This will lead to the extension of the construction period and the increase of construction cost. Contents of the invention [0003] The main purpose of the present invention is to provide a steel box girder and a steel box girder processing method to solve the problem of rework of the steel box girder in the prior art due to difficult quality control. [0004] According to one aspect of the present invention, a steel box girder is provided...
