PREFABRICATED RAIL BEAM FOR STRADDLE-TYPE RAIL TRANSIT VEHICLE, AND STRADDLE-TYPE RAIL TRANSIT SYSTEM

摘要

A prefabricated rail beam (1) for a straddle-type rail transit vehicle, and a straddle-type rail transit system. The prefabricated rail beam (1) for a straddle-type rail transit vehicle comprises a solid beam (10) and a prestressed rib (20). The prestressed rib (20) runs through the solid beam (10) in the length direction of the solid beam (10). The middle of the prestressed rib (20) is downwards bent relative to the two ends of the prestressed rib (20), and a ratio of a dead load to a live load of the prefabricated rail beam (1) ranges from 0.8 to 1.8.
