Rigid bridge hanging bracket and support combined supporting system

The utility model relates to a steel bridge hanging bracket and support combined supporting system, a hanging bracket is closer to the end portion of a distribution beam than a support, a first main beam and a second main beam are respectively contacted with the upper surface and the lower surface of the distribution beam, the first main beam is parallel to the second main beam, and the first main beam and the second main beam are both perpendicular to the distribution beam. The first steel column cylinders are located below the left side and the right side of the first main beam and used for supporting the first main beam, the second steel column cylinders are located below the left side and the right side of the second main beam and used for supporting the second main beam, the inner sides of the bottoms of the U-shaped bolts make contact with the lower surface of the distribution beam, and the U-shaped bolts are fixed relative to the first main beam. The distribution beams are supported by the hanging brac
