Steel structure concrete floor deformation joint node structure

The invention belongs to the technical field of building structures, and particularly relates to a steel structure concrete floor deformation joint node structure which comprises a concrete floor and a metal beam, the metal beam is arranged below the concrete floor, a deformation joint is reserved between every two adjacent concrete floors, and structural grooves are formed in the two side walls of each deformation joint. A plurality of embedded parts distributed at equal intervals are arranged in the concrete floor, one ends of the embedded parts extend into the deformation joint and are jointly and fixedly connected with a mounting plate, and bottom plates are fixedly connected to the inner bottom walls of the two structural grooves; and the opposite ends of the two bottom plates extend into the deformation joint, and a plurality of positioning rods which are uniformly distributed at intervals are jointly and fixedly connected between the opposite ends of the two bottom plates and the corresponding mounting
