Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering construction, in particular to an adjustable Bailey beam hinged support. Background Art

[0002] Bailey beams are widely used in the construction of large temporary structures such as construction trestles and construction platforms due to their strong spanning capacity and easy installation and disassembly. Bailey beam trestles usually use steel pipe piles as the foundation. Double or multiple I-beam load-bearing beams are set on the top of the steel pipe piles. Bailey beams are set on the load-bearing beams. Distribution beams are set on the Bailey beams. Finally, bridge panels are laid on the distribution beams to form a construction trestles or construction platforms for construction vehicles to pass. Usually, when Bailey beams are installed on load-bearing beams or abutments, they are simply placed on them and fixed with steel bars or steel clips. The contact parts are easily damaged by bumps and collisions, and the amount of on-site welding is large, which is inconvenient for construction. When the trestles or platform structures have a certain longitudinal slope, Bailey beams placed directly on the load-bearing beams or abutments are prone to instability, which poses certain safety hazards.
