Abstract
Description
Technical Field

[0002] Prefabricated bridges refer to a construction method in which the various parts of the bridge are prefabricated in a factory or prefabrication site and then transported to the construction site for assembly. This method can greatly reduce the time and labor intensity of on-site construction, and can also effectively improve the quality and safety of the bridge.
[0003] After searching, a Chinese patent discloses a 240-ton lifting device for an assembled inverted T-shaped cap beam (publication number CN218754501U). The patented technology includes a shoulder pole beam, a lifting hole, a U-shaped buckle, a steel wire rope and a steel strand. The U-shaped buckle is fixed to the shoulder pole beam to avoid the concrete from being chipped when the steel wire rope passes through the lifting hole to lift the component, thereby ensuring the quality of the cap beam. During installation, a trolley is used to connect the steel strand, so that the shoulder pole beam can be lifted directly, thereby improving work efficiency and saving work efficiency and manpower. By using the U-shaped buckle, the wear caused by the friction between the steel wire rope and the concrete during the lifting process is avoided, safety hazards are reduced, and safety risks are reduced, thereby solving the problem of shortened life of the steel wire rope due to wear and tear, thereby causing safety hazards.
