Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a temporary construction bridge. Background Art

[0002] During the construction process, if you encounter ditches, deep pits and pipe troughs, you need to build temporary bridges to facilitate the safe and smooth passage of vehicles and construction workers. At present, the common method is to use a symmetrically set steel frame structure, install I-beams on the steel frame structure, and lay steel plates or wooden boards on the I-beams. In this way, welding or bolting is generally used when installing I-beams. When welding is used for fixing, it is inconvenient to disassemble later; when bolting is used, it is necessary to drill holes in the I-beam, which changes the original structure of the I-beam and affects its later use.
