Combination bridge deck

The utility model discloses a combined bridge deck, the bridge deck has the characteristics that the weight is light and the steel consumption is less. The bridge deck includes: a. a bridge deck beam, longitudinal beam and crossbeam in interval arrangement are fixedly connected to form a lattice shape beam frame, b. a steel base plate, the steel base plate is respectively arranged on the upper side of each lattice of the bridge deck beam, each steel base plate is fixedly connected with the longitudinal beam and the crossbeam, c. a shear plate which is arranged along the vertical interval of the bridge deck, the shear plate is welded with the steel base plate, d. a reinforced concrete layer which is poured on the steel base plate. The utility model has the beneficial effects that the steel base plate is connected with the reinforced concrete layer and the lattice shape beam frame, the integral rigidity of the bridge is improved, under the condition of same bearing capacity, the weight and the steel consumption of the bridge deck can be decreased greatly, thereby the bridge deck is beneficial to decrease the production cost of the bridge, has the technical characteristics of comfortable driving and good wind-resistance, and is particularly applicable to be used as the bridge deck of large bridge and ultra-large bridge.
