Prefabricated assembly type steel-concrete composite structure bridge deck slab, joint structure and bridge

The invention discloses a prefabricated assembly type steel-concrete composite structure bridge deck, first stress ribs which extend in a first direction and are arranged in pairs in a third direction are arranged in the bridge deck, and the first stress ribs arranged in pairs in the third direction are divided into upper-layer stress ribs close to the top of the bridge deck and lower-layer stress ribs close to the bottom of the bridge deck. The first direction is different from the third direction; the bridge deck meets # imgabs0 #, and due to the fact that the tensile contribution degree of the high-performance concrete is considered, the tensile capacity of the steel bars and the tensile capacity of the high-performance concrete can be calculated through the formula, the height of the bridge deck is controlled, the dead weight of the bridge deck is reduced, the stress condition of the longitudinal and transverse beam assembly is improved, and the service life of the bridge deck is prolonged. And particular
