Bridge deck slab structure and steel-concrete composite beam structure

The utility model discloses a bridge deck slab structure and a steel-concrete composite beam structure, which belong to the field of bridge engineering, and are characterized in that two ends of a prefabricated bridge deck slab are respectively provided with a convex part and a groove, and the convex part and the groove are correspondingly assembled, so that the quick butt joint between the two prefabricated bridge deck slabs can be realized; and through the corresponding arrangement of the stud holes in the convex parts and the grooves, a plurality of stud mounting holes can be formed in the butt joint positions of the two spliced bridge decks, and then the end parts of the bridge decks can be quickly connected by embedding the studs. The bridge deck slab structure is simple in structure and convenient to assemble, rapid assembly of the prefabricated bridge deck slabs can be effectively achieved, the structural strength of the butt joint positions of the assembled bridge deck slabs is effectively guaranteed,
