PROBLEM TO BE SOLVED: To provide a connection structure for a bridge using a reinforced concrete floor slab and a connection method for an existing bridge using the reinforced concrete floor slab that may be installed simply and readily and offers sufficient load bearing ability.SOLUTION: A floor slab connecting part 10 is used with an existing concrete floor slab bridge 100 that uses a reinforced concrete floor slab 100a, and includes: a connecting upper reinforcing bar 50 that connects upper reinforcing bars 5a on both sides, so as to cover a work section X between separated edge parts of the reinforced concrete floor slabs 100a; a fixing part 21 on both ends connected to upper flanges 2a that face each other over a joint gap between separated edge parts of steel main girders 2 and an upper flange 3a of an end cross girder 3; a formed steel plate 20 disposed to cover the work section X and having a raised part 22 raised in a height direction above the fixing part 21; and a concrete part 60 cast on the work section X.SELECTED DRAWING: Figure 1 |
