The water pressures S1 and S2 (indicated by arrows in FIG. 5) received by 1 increase. Then, the water pressure S1 toward the center in the width direction of the opening O acts on the first waterstop plate 10, and the water pressure S2 toward the inside of the opening O acts on the second waterstop plate 11.

Then, the first overlapping surface 12a of the reinforcing member 12 overlaps the inner surface 10c of the first waterstop plate 10, and the second overlapping surface 12b of the reinforcing member 12 overlaps the inner surface 11c of the second waterstop plate 11, so that the first stop A part of the water pressure S1 toward the center in the width direction of the opening O acting on the water plate 10 is opposite to the water pressure S2 acting on the second waterstop plate 11 via the reinforcing member 12. It acts on the orientation direction S1a. Further, since the first overlapping surface 12a of the reinforcing member 12 overlaps the inner surface 10c of the first waterstop plate 10 and the second overlapping surface 12b of the reinforcing member 12 overlaps the inner surface 11c of the second waterstop plate 11, the second stop A part of the water pressure S2 acting on the water plate 11 toward the inside of the opening O reaches the first water stop plate 10 via the reinforcing member 12, and the direction S2a opposite to the water pressure S1 acting on the first water stop plate 10. Acts on. Therefore, a part of the water pressure S1 acting on the first waterstop plate 10 is offset by the force in the S2a direction, and a part of the water pressure S2 acting on the second waterstop plate 11 is offset by the force in the S1a direction. ..

From the above, in the waterproof device 1 according to the embodiment, a part of the water pressure S1 acting on the first waterstop plate 10 is canceled by the force in the S2a direction, and one of the water pressures S2 acting on the second waterstop plate 11. The portions are offset by the force in the S1a direction. Therefore, the waterproof device 1 can reduce the thickness and weight of the first waterstop plate 10 and the second waterstop plate 11, and can reduce the weight of the first waterstop plate 10 and the second waterstop plate 11 that close the opening O. Can be planned.

Further, in the waterproof device 1, one end 10a of the first waterstop 10 is attached to the vertical 3a, and the second waterstop 11 connects the other ends 10b of the first waterstop 10. Therefore, even after being installed in the opening O, the opening / closing door 4 can be opened / closed, and the opening / closing door 4 can be entered / exited.

Further, in the waterproof device 1, a pair of reinforcing members 12 are provided, and the first overlapping surfaces 12a of the reinforcing members 12 are overlapped on the inner surfaces 10c of the first waterstop plates 10 which are different from each other. Therefore, the pair of first waterstop plates 10 A part of the water pressure S1 acting on each of them can be made to act on the second waterstop plate 11 via the reinforcing member 12 in the direction S1a opposite to the water pressure S2 acting on the second waterstop plate 11. Therefore, the thickness and weight of the second waterstop 11 can be further reduced.

In the waterproof device 1, since the facing surface 12c connecting the first overlapping surface 12a and the second overlapping surface 12b of the reinforcing member 12 is a flat surface, one of the water pressures S1 in which the reinforcing member 12 acts on the first waterstop plate 10. The portion can be surely acted on the second waterstop plate 11, and a part of the water pressure S2 acting on the second waterstop plate 11 can be surely acted on the first waterstop plate 10.

Since the reinforcing member 12 is trapezoidal in the waterproof device 1, the reinforcing member 12 can be used as a stepping stone to easily enter and exit from the opening O after installation.

Further, as shown in FIG. 6, the waterproof device 1 described in the above-described embodiment can also be installed in the opening O provided with the pair of hinged doors 8 and 8 as the opening / closing body. The pair of hinged doors 8 and 8 are arranged in the width direction of the opening O, and one end portion closer to the vertical 3a is rotated around an axis parallel to the vertical direction to open and close the opening O. That is, as shown by the solid line in FIG. 6, the pair of hinged doors 8 and 8 are positioned parallel to the width direction of the opening O and close the opening O. Further, as shown by the dotted line in FIG. 6, the hinged doors 8 and 8 are arranged around the axis of one end so that the other end of the hinged doors 8 and 8 faces the outdoor side or the indoor side from the position shown by the solid line in FIG. By being rotated, the opening O is opened. The rotation of the hinged doors 8 and 8 may be performed manually or automatically by a driving device such as a motor. In the waterproof device 1 described above, since the first waterstop plate 10 and the second waterstop plate 11 protrude from the opening O on the side where the water pressure is received, that is, on the outdoor side, after installation in the opening O. Also, it is possible to prevent the first waterstop plate 10 and the second waterstop plate 11 from interfering with the hinged doors 8 and 8 that open and close the opening O.
