PROBLEM TO BE SOLVED: To improve function by covering a duckboard at the same level as a floor face above a drain trench provided in an entrance floor part, inserting a water stop in the slit-like through hole, and lifting it. SOLUTION: Waterproofing structure is constituted by a drain trench 4 provided in a floor of an entrance, a duckboard 6 having the top face disposed flush with a floor face and formed by disposing plate members 7 in parallel with the entrance so as to form slit-like through holes 8, and a water stop plate 12 consisting of a water stop body 10 and a float 11 inserted in the through hole 8 at a position nearest to a hanging door 2. An upper edge is positioned in the through hole 8 in a state where the lower edge of the water stop plate 12 is mounted on the bottom face of the drain trench 4. When water flow exists from a bathroom 1, inflow for a dressing room 3 is blocked since the water level of the drain trench 4 is increased, the water stop plate 12 is protruded from the duckboard 6 and the water flow is dammed up to be drained to the drain trench 4. When drainage is completed, the water level is lowered to lower the upper edge of the water stop plate 12, and returned to the through hole 8. Thereby walking is safely performed because the entrance is formed flush with the floor face, and facility cost can be reduced because structure is simple. |
