Transition beam for connecting segmental beam and small box beam

The utility model discloses a transition beam used for connecting a segmental beam and a small box beam, which comprises a transition beam body, one end of the transition beam body in the length direction is a first butt joint end used for being in butt joint with the segmental beam, and the first butt joint end corresponds to the cross section of the segmental beam; the other end of the transition beam body in the length direction is a second butt joint end used for being in butt joint with a small box beam, and the second butt joint end corresponds to the cross section of the small box beam. Lofting from the first butt joint end to the second butt joint end to form a variable-cross-section beam body, so that the segmental beam and the small box beam are in smooth transition connection with each other; a cushion block does not need to be additionally arranged at the top of the bridge pier to make up the height difference between the segmental beam and the small box beam, construction is simplified, the whole
