Embodiment Construction

[0069] A forming method of a steel box type composite beam, the structure of the composite beam includes a top plate, a corrugated plate and a bottom box. The processing method of the steel box-type composite beam includes blank cutting and pretreatment in the early stage, bottom box processing, corrugated plate processing, top plate processing, and assembly welding process. Specific steps include:

[0070] A. Uncoil and level the steel coil, and cut it into equal-length bottom box bottom plate blanks, bottom box top plate blanks, corrugated web plate blanks and top plate blanks for forming the bottom box according to the design size; use an uncoiler, leveling The steel coil is unrolled, roughly calibrated and finely calibrated into a steel plate with flatness that meets the requirements, and transported to the cutting station by the roller conveying equipment. According to the design requirements, the steel coil is cut longitudinally and then transversely by means of the shea...

Abstract

Disclosed is a steel box type composite beam forming method. A split type processing method is utilized in a bottom box and a plug welding technology and an anti-deformation technology are utilized to effectively solve the problems of positioning of force transmission ribs, deformation of the bottom box and the like, and the prefabrication efficiency of steel-concrete composite bridges is improved by reasonably adjusting production processes. The adopted technical scheme of the steel box type composite beam forming method comprises utilizing steel plates as raw materials, leading the raw materials to be subjected to top plate forming, bottom box forming and wave plate forming, and performing assembling and welding to form a prefabricated steel box type composite beam. According to the steel box type composite beam forming method, assembly line production is utilized and large-scale processing and assembling of bottom boxes can be achieved in factories.

Description

technical field [0001] The invention relates to a processing method of a box girder structure, in particular to a forming method of an assembled steel box composite girder suitable for industrial processing and stable in structure. Background technique [0002] Concrete bridges conform to the requirements of the last century and play a pivotal role in bridge construction. To a certain extent, they meet the needs of social and economic development for transportation facilities, improve the living environment, and promote economic growth. effect. However, there are many defects in the construction of concrete bridges, the most important of which are two points: [0003] ① It consumes a huge amount of sand, stone and cement, and the production of cement and aggregate and the large amount of construction waste generated have paid a huge environmental protection price; [0004] ② Concrete bridges frequently suffer from diseases and the durability of concrete structures is poor....
