REINFORCING TEMPORARY BRIDGE AND ASSEMBLING TEMPORARY BRIDGE STRUCTURES

摘要

PURPOSE: A reinforcing temporary bridge and a prefabricated temporary bridge structure are provided to shorten a construction period and to facilitate an installation by reducing welding joint parts and avoiding the excessive reinforcement of a temporary bridge. CONSTITUTION: A reinforcing temporary bridge and a prefabricated temporary bridge structure comprise an upper plate(100) and a pair of lateral side girders(200). The bottom surface of the upper plate comprises a plurality of longitudinal ribs(110) and a lateral rib(120). The lateral side girders face each other and are joined in the bottom surfaces of both edges of the upper plate in a longitudinal direction. One area in which the longitudinal and lateral ribs cross is formed with a cutting groove(130) to reduce welding joint parts.
