Assembly type dense rib hollow shear wall structure system

The utility model discloses an assembly type dense rib hollow shear wall structure system. The assembly type dense rib hollow shear wall structure system comprises a prefabricated gridding shear wall and a reinforcement cage, wherein the prefabricated gridding shear wall and the reinforcement cage are arrayed at intervals along the horizontal direction; beam ribs which extend along the horizontal direction are buried in the prefabricated gridding shear wall; and ends of the beam ribs extend out of the prefabricated gridding shear wall so that connecting structures which are bent outwards and are connected with the reinforcement cage are formed. By the assembly type dense rib hollow shear wall structure system, the ends of the beam ribs buried in the prefabricated gridding shear wall extend out of the prefabricated gridding shear wall so that the connecting structures which are bent outwards and are connected with the reinforcement cage are formed; after the reinforcement cage is mounted in place, the connecting structures of the beam ribs are bent inwards and are fixedly bound with vertical ribs of the reinforcement cage; and concrete pouring is performed on the reinforcement cage so that an upright column is formed. The problem that the beam ribs of the prefabricated gridding shear wall cannot penetrate in the vertical ribs of the reinforcement cage in the prior art is solved.
