Sandwich board type steel-concrete combined cross section cable-stayed bridge main beam
The invention relates to the technical field of a combined beam cable-stayed bridge, in particular to a sandwich board type steel-concrete combined cross section cable-stayed bridge main beam. The sandwich board type steel-concrete combined cross section cable-stayed bridge main beam comprises a concrete bridge deck and lower steel structures, wherein the lower steel structures are fixedly arranged at the two sides of the bottom of the concrete bridge panel, and are in uniform arrangement along the direction of the bridge, the lower steel structures arranged at the two sides are connected through connecting components, the top of each connecting component is connected with the bottom of the concrete bridge deck, and upper steel structures are respectively arranged in the positions, corresponding to the lower steel structures, of the two sides of the top of the concrete deck. The top of the concrete bridge deck is additionally provided with a layer of steel structure, so that the concrete bridge deck is arranged in the middle or the middle part of the integral cross section of the bridge main beam, i.e., the steel structure is used for sharing pulling stress capable of being received by concrete, so that the goal of eliminating or reducing the concrete pulling stress is achieved, the use durability of the combination beam is improved, meanwhile, the stress state of the bridge deck is improved, the economic span length of the highway combined beam cable-stayed bridge is greater, and wider application prospects are realized.
