  When installing the seat 10 in the opening O, that is, assembling the waterproof device 1, first, the holding member 20 is attached to the vertical stand 3 a, and the central portion of the opening O is closed by the door 5 of the opening / closing door 4. Then, with the folded portion 14 facing the door 5 of the opening / closing door 4, both ends in the width direction of the sheet 10 and the core material 11 are inserted into the sheet holding portion 22 from the upper end of the holding member 20, and both ends of the sheet 10 and The core material 11 is moved in the sheet holding portion 22 toward the lower end of the holding member 20. Then, both ends of the sheet 10 and the core material 11 are sandwiched between the sheet holding portions 22 of the holding member 20, and the sheet lower portion 13 where the core material 11 of the sheet 10 is not provided is passed through the gap provided at the lower end of the holding member 20. It is drawn on the surface 7 and extends toward the outdoor side along the floor surface 7.

  The width of the sheet 10 is larger than the width W of the opening O (see FIG. 2), and is set to the following width. That is, the sheet 10 has a slight slack in a state where both ends of the sheet 10 are held by the holding member 20. That is, the holding member 20 holds the sheet 10 in a state where the sheet 10 has a slack, and allows the sheet 10 to bend toward the opening / closing door 4 side with respect to the holding member 20. In addition, depending on the dimensional difference between the width of the sheet 10 and the width W of the opening O, the sheet 10 is appropriately folded starting from the folded portion 14, and the sheet 10 installed in the opening O has a slight slack. You may have.

  The vertical length of the seat 10 is longer than the vertical length of the predetermined portion 41 of the open / close door 4 and is set to the following length. That is, in a state where the sheet 10 is held by the holding member 20, it is possible to hang the sheet lower portion 13 on the floor surface 7 and to follow the floor surface 7. The seat 10 is installed in a state where the seat lower portion 13 is extended toward the outdoor side along the floor surface 7. In other words, the seat 10 is disposed so as to face the floor surface 7 provided in the seat lower portion 13 and to be separated from the open / close door 4 as the seat lower portion 13 moves toward the front end side.

  And as shown in FIG. 4, the press member 30 is arrange | positioned on the sheet | seat lower part 13, and the sheet | seat 10 is installed so that the opening part O may be plugged up. Then, as shown in FIG. 5, after opening the center part of the opening part O with the door 5 of the opening-and-closing door 4, an operator passes through the opening part O across the center of the width direction of the sheet | seat 10, etc. Then, the stationary suction cup 50 is moved indoors. Then, as shown in FIG. 6, the opening O is closed by the door 5 of the opening / closing door 4, and then, as shown in FIG. 7, the string-like object 51 is pulled to the indoor side, and then the suction cup 50 for fixing is attached to the door 5. It is fixed to the indoor side by adsorbing it to the inner surface of. Thus, the pressing member 30 in a state where the sheet 10 integrally covers the predetermined portion 41 and the portion adjacent to the predetermined portion 41 of the wall 3 and the sheet lower portion 13 extends toward the outdoor side along the floor surface 7. Thus, the sheet 10 is pressed toward the floor surface 7, the wall portion 3 of the structure S, the vertical stand 3 a, and the doors 5 of the open / close door 4. Thus, the waterproof device 1 is assembled.

  In the waterproof device 1 of the present embodiment, when the outdoor water volume increases due to flooding, guerrilla heavy rain, or the like, the seat lower portion 13 first comes into contact with water. The seat lower portion 13 is pressed toward the floor surface 7 by the water pressure, and the seat lower portion 13 comes into close contact with the floor surface 7. Thereby, it is suppressed that water permeates from between the seat lower portion 13 and the floor surface 7. In addition, since the sheet lower portion 13 is pressed toward the floor surface 7 by the pressing member 30, inundation through the gap between the sheet lower portion 13 and the floor surface 7 is further suppressed even in the case of a low water level. . Further, the pressing member 30 can suppress the sheet lower portion 13 from being lifted by a water flow or the like. The sheet 10 can integrally cover the predetermined portion 41 and the floor surface 7 adjacent to the predetermined portion 41 by water pressure.

  Further, in the seat 10, the portions covering the vertical stand 3 a and the doors 5 of the open / close door 4 are pressed toward the wall 3, the vertical stand 3 a, and the doors 5 of the open / close door 4 by water pressure. Thereby, the sheet | seat 10 can cover the predetermined part 41 of the door 4 and the part adjacent to the predetermined part 41 among the structures S integrally. When the sheet 10 is pressed by water pressure, the sheet 10 is in close contact with the wall 3, the vertical stand 3 a, and the like, and water can be prevented from entering between the sheet 10, the wall 3, and the vertical stand 3 a. .

  Moreover, the sheet | seat 10 can suppress the flooding to the indoor side through these clearance gaps by plugging the clearance gap between the wall part 3 and the vertical stand 3a with water pressure. The seat 10 can suppress water from entering the indoor side from the opening O by closing a gap between the predetermined portion 41 of the open / close door 4 and the floor surface 7 adjacent to the predetermined portion 41 by water pressure.

  Since the sheet 10 is pressed against the wall 3, the vertical stand 3 a, and each door 5 of the open / close door 4 by water pressure, as the water level increases, the adhesion to the wall 3, the vertical stand 3 a and the like increases. Moreover, the obstruction | occlusion property which obstruct | occludes each clearance gap increases. Therefore, the sheet | seat 10 can suppress the water penetration performance according to a water level, and can suppress the inundation to an indoor side appropriately.

  According to the waterproof device 1 according to the first embodiment, since the suction cup 50 for fixing fixed to the indoor side is provided at the distal end portion of the string-like object 51 attached to the upper end portion of the sheet 10, the opening portion O is blocked. After the seat 10 is installed, it can enter the room through the opened opening O. Thereafter, the door 4 is closed, and the string-like object 51 is pulled to the indoor side via the fixing suction cup 50 and fixed to the indoor side, so that the upper end of the seat 10 is installed in the opening O without being loosened. be able to. Accordingly, even after the waterproof device 1 is installed, the waterproof device 1 can enter the room through the opening O while maintaining the state in which the sheet 10 can stop the opening O.

  Further, since the waterproof device 1 suppresses water intrusion from the opening portion O by the sheet 10, the weight can be reduced, and the sheet 10 can be folded and stored compactly when not installed in the opening portion O. I can keep it.
