[0002] Bailey plates, also known as Bailey frames or trusses, are components used in temporary structures such as bridges and building supports. They have high load-bearing capacity and stability. Since Bailey plates can be reused in projects, they are widely used in bridge construction projects.

[0003] Bailey panels usually include a square assembly outer frame and a diagonal rod assembly supporting the assembly outer frame. The assembly outer frame includes an upper crossbeam, a lower crossbeam, and a plurality of connecting vertical rods connecting the upper crossbeam and the lower crossbeam. The diagonal rod assembly includes at least one group of diagonal bracing units, and the diagonal bracing unit is composed of two cross-connected diagonal bracing rods. The ends of the diagonal bracing rods are welded and fixed to the upper crossbeam / lower crossbeam. During the lifting and transportation of the Bailey panel, the assembly outer frame is more prone to collision and wear than the diagonal rod assembly, making the assembly outer frame of the Bailey panel more prone to damage. When the assembly outer frame of the Bailey panel is damaged, since the diagonal rod assembly and the assembly outer frame are welded and fixed, the entire Bailey panel needs to be replaced. Utility Model Content

[0004] In order to reduce the replacement cost of Bailey plates, the present application provides a Bailey plate.

[0005] The present application provides a detachable Bailey sheet using the following technical solution:
