Provided is a slab bridge structure wherein the rigid bonding strength between bridge girders and concrete bridge footers is improved. A slab bridge structure forms a rigid bonding structure in which slab concrete 3 is poured across a bridge girder 1 in the longitudinal direction in between the side faces of the bridge girders aligned in the bridge width direction, and consolidation concrete 12, in which a bridge girder portion 1' supported by a bridge seat 2a is embedded, is added to the bridge seat of a concrete bridge footer 2 that further supports the bridge girder, thereby bonding the slab concrete and the concrete bridge footer via the consolidation concrete. The slab bridge structure comprises a coupling rod 13 that is embedded in the concrete bridge footer and projects up from the bridge seat of the bridge footer, and a coupling plate 14 that couples the top ends of adjacent bridge girder portions. The slab bridge structure is configured so that the projecting portion of the coupling rod is inserted into the coupling plate, a stopper is provided for the top end projection of the coupling rod that is inserted into the coupling plate, and the bridge girders are coupled to the concrete bridge footers by sealing the seat of the stoppers to the top face of the coupling plate. |
