The invention discloses a method for limiting displacement of beam-end corners at a continuous part of a bridge floor and prefabricated beam bodies. Grooves are reserved in the top sealing anchor surface of a main beam and located in the portions, close to the beam ends, of the tops of prefabricated I-shaped beams at the two ends of the continuous part of the bridge floor, before rebar of the bridge floor is bundled, prefabricated concrete wedge blocks are placed in the reserved grooves, and then continuous processing operation is conducted on the bridge floor. The prefabricated concrete wedgeblocks adopt C50 compensation shrinkage steel fiber concrete for prefabricating, the lengths of the wedge blocks are adjusted with the width of the bridge floor, and the section form can be set according to actual conditions. The method and the prefabricated beam bodies can solve the technical problems that in the bridge operation process, under the loading effect, according to the main beam, larger corners of the prefab
