Novel beam grillage through arch bridge
The invention discloses a novel beam grillage through arch bridge. The novel beam grillage through arch bridge comprises arch feet, arch ribs, suspenders and a bridge deck system, each arch rib is connected with two adjacent arch feet, the bridge deck system is supported by the arch feet, the top parts of the suspenders are suspended below the arch ribs, the bottoms are suspended on the bridge deck system, the bridge deck system comprises a beam grillage structure and a bridge deck slab located on the beam grillage structure and integrally poured with the beam grillage structure, the beam grillage structure comprises two side beams, two side girders, a plurality of middle beams uniformly distributed between the two side beams, and a plurality of middle girders uniformly distributed between the two side girders, and the ends of the side beams and middle beams are symmetrically provided with the suspension points of the suspenders. The bridge deck system uses the beam grillage structure of which the girders and beams are connected rigidly, the suspenders are connected with the suspension points of the bridge deck system through rigid girders, each suspension point can carry load uniformly, and the anti-fatigue performance of the structure is improved; the whole beam grillage structure serves as a load carrying component, the load bearing of the structure is uniform, and the integrality is good.
