Common formwork for road precast box girders
Precast box girder is widely used in the construction of expressway. The traditional precast box girder formwork is widely used, which has the advantages of low cost, simple structure and easy operation. However, with the advancement of technology and the increasing requirements for road construction efficiency, its disadvantages are increasingly obvious: low accuracy, poor stability, limited span, etc. Therefore, it is rare in the projects that road construction require a higher precision and construction speed, which use more upgraded hydraulic box girder. However, due to the low cost of traditional box girder, the market is still reserved in some highway construction. Limited by the technical application space and cost factors, our company reasonably optimized the traditional template to improve the accuracy and reduce the operation time as much as possible. For example, change the design concept, improve the welding accuracy. Maximize the advantages and avoid the disadvantages when the templates are put into use and meet project expectations.
