The steel structure bridge is more and more favored by the characteristics of light weight, beautiful shape, energy conservation, environmental protection and uniform stress. In order to ensure the processing quality of the steel box girder, most steel box girder bridges adopt the structural form of in-site processing and in-site installation. Welding is commonly used for on-site connection of the steel box girders, and the welding between the two spliced steel box girders mainly adopts a form of on-site construction welding. The welding method is divided into flat welding, vertical welding, overhead welding and the like.
Because the welding quality has higher requirements on the temperature and the humidity of the site, the construction progress and the quality control of the site welding of the steel structure are often restricted when the site encounters bad weather such as strong wind, overcast and rainy days and the like. The traditional windproof and rainproof measures are that a plurality of fixed supports are welded on a bridge floor, and fireproof canvas is used for surrounding and blocking the supports.
Although the process ensures the construction quality to a certain extent, the process also has obvious disadvantages, for example, the support steel pipe is randomly welded with the bridge floor, paint on the bridge floor and a steel plate surface layer are damaged, each section of welding needs to be specially subjected to baffle operation, the construction efficiency is low, horizontal layers of workers are uneven, and the erection shape is random; particularly, a large amount of welding smoke is generated in the welding process of the steel box girder, and the smoke can be directly diffused, so that the environmental pollution is caused.
