The application discloses a reinforcing device for a building floor opening of an existing building. The first steel beam, the second steel beam, the third steel beam and the fourth steel beam are abutted to the bottom of the building floor of the existing building; the bottom end of the four L-shaped edge plates is connected to the side wall of the first steel beam, the second steel beam, the third steel beam and the fourth steel beam respectively, the four L-shaped edge plates are enclosed to form a rectangular structure, the position and size of the rectangular structure correspond to the position and size of the first opening, the outer side wall of the rectangular structure forms a groove with the inner side wall of the second opening of the building floor of the existing building; the plurality of steel beams cut off in the building floor of the existing building are connected to the outer side wall of the rectangular structure, and the cast-in-place concrete structure is arranged in the groove; the top of the L-shaped edge plate is flush with the top of the first opening. Therefore, the reinforcing device for the building floor opening of the existing building not only realizes effective reinforcement of the opening area of the building floor of the existing building, but also has multiple advantages such as convenient construction and reliable structure.
