  A method for installing the sheet 10 in the opening O, that is, a method for assembling the waterproof device 1 will be described with respect to an embodiment.

  When the seat 10 is installed in the opening O, that is, the waterproof device 1 is assembled, first, as shown in FIG. 3, the holding member 20 is attached to the vertical stand 3a, and the tension member 50 is appropriately expanded and contracted to Both ends of the member 50 are attached to the vertical stand 3a. At this time, the longitudinal direction of the projecting member 50 is parallel to the horizontal direction, and the projecting member 50 is disposed slightly above the upper end of the predetermined portion 41.

  Then, 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 are directed toward the lower end of the holding member 20 in the sheet holding portion 22. Move with. 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. Further, the hook portion 53 of the hook member 51 is inserted into the suspension hole 12, and the upper end portion of the sheet 10 is suspended from the tension member 50. Further, in the present invention, the sheet 10 may be suspended from the projecting member 50 first, and then the sheet 10 may be retained by the holding member 20. Alternatively, the sheet 10 may be suspended from the tension member 50 after the pressing member 30 is disposed on the sheet 10. The timing at which the sheet 10 is suspended from the tension member 50 may be appropriately selected according to the configuration of the hook member 51 and the tension member 50, the situation at the site, and the like.

  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. Further, the projecting member 50 that suspends the upper end portion of the seat 10 is provided at a distance from the opening / closing door 4. Therefore, the seat 10 has a slack enough to keep the seat 10 spaced from the open / close door 4 in a state where the seat 10 is held by the holding member 20 and the upper end portion is suspended from the projecting member 50. It is preferable. When the upper end portion of the sheet 10 is suspended from the tension member 50, depending on the dimensional difference between the width of the sheet 10 and the width W of the opening O, the adjacent suspension holes 12 overlap each other. It is desirable that the sheet 10 is appropriately folded and the sheet 10 installed in the opening O has a slight slack.

  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.

  Then, the pressing member 30 is disposed on the sheet lower portion 13. 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. The sheet 10 is pressed toward the floor 7, the wall portion 3 of the structure S, the vertical stands 3 a and 5 a, and the doors 5 of the open / close door 4. Thus, the waterproof device 1 is assembled.

  In the waterproof device 1 according to the first 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 lower sheet portion 13 is pressed toward the floor surface 7 by the pressing member 30, water infiltration through the gap between the lower sheet sheet 13 and the floor surface 7 is more reliably suppressed even in the case of a low water level. Is done. 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 stands 3 a, 5 a and the doors 5 of the open / close door 4 are pressed toward the walls 3, the vertical stands 3 a, 5 a, and the doors 5 of the open / close door 4 by water pressure. The 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.
