Description

Technical Field

[0001] The present invention relates to the technical field of precast box girder equipment, and particularly to an intelligent and environmentally friendly spliced precast box girder formwork structure. Background Art

[0002] In the production process of precast box girders, the installation and removal of the internal formwork traditionally rely on manual assembly. This method is not only cumbersome in operation but also generates a large amount of waste. For the casting operation of precast small box girders with a span exceeding 25 meters, although there is a solution using a pull-out internal formwork, such as the "integral pull-out small box girder hydraulic internal formwork and formwork collection method" disclosed in the Chinese patent application with the application publication number CN111421656A. This method uses multiple hydraulic systems to jointly control the retraction of the side formwork, bottom formwork, and top formwork to achieve rapid recovery. However, this solution has the problem that at least 12 hydraulic cylinders need to be synchronously controlled, which requires the hydraulic system to not only have a high sealing performance but also ensure that all 12 hydraulic cylinders can work properly. This undoubtedly increases the operational complexity of the system and may lead to frequent failures. At the same time, additional steel wheel plates are required for the overall pull-out, which is even more troublesome. Therefore, we propose an intelligent and environmentally friendly spliced precast box girder formwork structure. Summary of the Invention
