Abstract (en)
[origin: EP2218825A2] The bridge has longitudinal supports (1) rigidly connected with each other and arranged adjacent to each other in cross section. The supports comprise a U-shaped cross section with a lower flange (3) and two upper belts (4) with a central recess (5) for receiving rail fasteners (6) and a rail. The longitudinal supports are formed as a reinforced concrete composite beam comprising steel beams (10, 22) and a concrete support (16). The steel beams are arranged together such that bars of the beams lie on different axes. An independent claim is also included for a producing a reinforced-concrete composite beam for the bridge.
