The invention discloses a steel-concrete composite beam. The steel-concrete composite beam comprises a prefabricated reinforced concrete bridge deck slab and a steel beam which are connected, whereinthe prefabricated reinforced concrete bridge deck slab is located at the top of the steel beam and provided with reserved group nail holes, embedded steel bars are arranged in the prefabricated reinforced concrete bridge deck slab and extend into the reserved group nail holes, the steel beam is provided with group nails, each group nail comprises a plurality of welding nails, and steel bar meshesare arranged in the reserved group nail holes and are in a grid shape. The steel-concrete composite beam is advantaged in that the reserved group nail holes are formed in the prefabricated reinforcedconcrete bridge deck slab, the group nails on the steel beam can completely enter the reserved group nail holes, then, a reinforcing mesh is arranged in the reserved group nail hole, the welding nailsextend into grids of the st
