Nov 10, 2021
Bailey panel have the characteristics of simple structure, convenient transportation, fast erection, large load capacity, good interchangeability, and strong adaptability.
The "321" steel bridge is a fast-assembled bridge developed on the basis of the original British Bailey truss bridge and combined with China's national conditions and actual conditions. It was finalized and produced in 1965 and has been greatly developed in China. It is widely used in national defense, combat readiness, Traffic engineering and municipal water conservancy engineering are the most widely used assembled bridges in China. It has the characteristics of simple structure, convenient transportation, quick erection, large load capacity, good interchangeability and strong adaptability.
The “HD200” prefabricated highway steel bridge increases the height of the truss, improves the bearing capacity, enhances the stability, increases the fatigue life, and improves the reliability. Compared with the 321 steel bridge, under the same combination, the strength is increased by 33%, and the rigidity is increased by 2.3 times. The scope of application is 4.2M for single-lane bridge deck, 9.14-76.2M for combined span, 7.4M for two-lane bridge deck, and 9.14-57.91M for combined span.
64 military beams were used by the German army during World War II.
