PURPOSE: Incremental launching equipment and method for constructing a rail-type concrete upper slab of a composite bridge using a rail for a shearing connector are provided to easily launch an upper slab by using a rail for a shearing connector instead of a stud-type shearing connector. CONSTITUTION: Incremental launching equipment for constructing a rail-type concrete upper slab of a composite bridge comprises a launching jack(410) which consecutively launches upper slab segments on an upper flange(210) of a steel box girder, a launching rail(430) which is arranged in the launching direction in a launch opening formed in the upper flange and guides the launch of the upper slab segments, a lateral support beam, and a rail for a shearing connector which is arranged on the side of the launching rail, guides the launch of the upper slab segments with the launching rail, and serves as a shearing connector when combining the upper slab segments with the upper flange. |
