PROBLEM TO BE SOLVED: To provide a precast floor slab and a bearing plate for replacing work, and a replacing construction method of a cast-in-place RC floor slab of a composite girder for stopping the passing at night and opening the passing over the whole surface in the daytime by using the precast floor slab and the bearing plate for the replacing work. SOLUTION: This replacing construction method of the cast-in-place RC floor slab of the composite girder, uses the precast floor slab 1 for the replacing work constituted by inserting a sheath 2 having a cross-sectional cavity shape of an oval shape or an elliptic shape or a rectangular shape into a PC steel bar inserting hole 4 for introducing a prestress into the floor slab, the bearing plate 3 of the precast floor slab for the replacing fork formed by boring an oval or elliptic or rectangular hole in response to the cross-sectional cavity shape of the PC steel bar inserting hole, and a bearing plate of the same floor slab as the precast floor slab for the replacing work.
