PROBLEM TO BE SOLVED: To provide a floor slab reinforcing method of a bridge, a bridge floor slab structure, and a heat insulation member for realizing traffic opening in an early stage and preventing generation of cracks in filling concrete or the like or floor slab reinforcing concrete installed during the construction in the floor slab reinforcing construction of a bridge.SOLUTION: The floor slab reinforcing method of a bridge according to the present invention includes a floor slab laying step, an installation step, a heat insulation step and an early stage pavement step. In this case, in the case of floor slab replacing construction, a precast floor slab is newly laid in the laying step, a concrete part is formed by installing concrete or the like to a joint part of the precast floor slab in the installation step, a heat insulation material or the like is laid on the concrete part to form a heat insulation layer in the heat insulation step, and a pavement is laid on the heat insulation layer in the state that the concrete or the like of the concrete part is in the state of a young material age in the early stage pavement step. |
