<p>PROBLEM TO BE SOLVED: To provide a slab bridge in which falling of a concrete form due to secular deterioration or the like is suppressed by enhancing the strength and durability of the concrete form, and which is accordingly improved in strength and durability.SOLUTION: A slab bridge 1 is configured by: placing slab concrete 4 between bridge girders 2; additionally placing connection concrete 12 for embedding a bridge girder part 11 supported on a bridge bottom surface 13 of concrete bridge footings 3 supporting the bridge girders 2, the slab concrete 4 and the concrete bridge footings 3 being in a concrete connection state; preparing coupling bars 14 embedded in the concrete bridge footings 3; penetrating projections of the coupling bars 14 into the bridge girder part 11; providing stoppers at upper end projections of the coupling bars 14 penetrated into the bridge girder part 11; seating the stoppers on a top face of the bridge girder part 11; and connecting the bridge girders 2 to the concrete bridge footings 3. Tabular concrete forms 15 arranged on the underside of the slab bridge 1 are formed of resin concrete. Meanwhile, H-shaped steels are used for the bridge girders 2 and the concrete forms 15 are mounted on lower flanges 8 so as to close between the bridge girders.</p> |
