A

To provide a floor slab drainage structure capable of accommodating to the thinness of a floor slab.SOLUTION: A floor slab drainage structure 1 comprises: a catch basin pedestal 20 that has a recess 21 recessed in an upper surface 101 of a floor slab 100 and supports a catch basin 10 into which a road surface drainage R of an upper surface 201 of a pavement 200 provided above the floor slab 100 flows through the recess 21; and a lead-out pipe 30 that communicates with the recess 21 of the catch basin pedestal 20 below the catch basin pedestal 20 and leads the road surface drainage R flowing from the catch basin 10 through the recess 21 of the catch basin pedestal 20 to a lower surface 102 of the floor slab 100. The floor slab drainage structure further comprises a flange 40 that is provided at a lower end of the lead-out pipe 30 and is connectable to a flange 51 of a discharge pipe 50 that discharges the road surface drainage R led to the lower surface 102 of the floor slab 100 by the lead-out pipe 30 to the lower side of the floor slab 100, which allows the lead-out pipe 30 and the discharge pipe 50 to be connected at a short distance while accommodating to the thinness of the floor slab 100.SELECTED DRAWING: Figure 1
