The invention discloses a rail traffic steel structure bridge which structurally comprises supports, cross beams, longitudinal beams, lower chords, lower flat longitudinal rods, a ship collision preventing device, oblique rods, nodes, vertical rods, main rods, upper flat longitudinal beams, upper chords and bridge portal frames. The supports are fixedly connected with the cross beams, the longitudinal beams are connected with lower chords, the lower flat longitudinal rods are connected with the ship collision preventing device, and each ship collision preventing device consists of steel bars,an anti-collision ring, an inner steel enclosure, an outer steel enclosure, steel plates and a closed-loop pouring jacket. The steel bars are connected with the anti-collision ring, the anti-collisionring is connected with the inner steel enclosure, the inner steel enclosure is fixedly connected with the outer steel enclosure, the steel plates are connected with the closed-loop pouring jacket, the oblique rods are connected with the nodes, the vertical rods are connected with the main rods, and the upper flat longitudinal beams are connected with the upper chords. The rail traffic steel structure bridge is provided with the ship collision preventing device which are used for preventing incoming and leaving ships from being collided with the bridge and is arranged in the middle of the bridge.
Description
technical field [0001] The invention is a rail transit steel structure bridge, which belongs to the field of steel structure bridges. Background technique [0002] The main load-bearing structure adopts steel bridges, that is, steel structure bridges and steel bridges. [0003] The prior art discloses a rail transit steel structure bridge with application number CN201010618736.7, which includes a steel bridge deck extending longitudinally, a concrete deck and a rail platform. Concrete panels include perforated steel plates, transverse reinforcement, longitudinal reinforcement, reinforcement mesh, rail platform reinforcement and concrete layers. The perforated steel plate is welded on the steel bridge deck in the longitudinal direction, and has a plurality of through holes in the longitudinal direction, and the through holes on two adjacent perforated steel plates are aligned in the transverse direction. The transverse steel bars respectively pass through the through holes ...
