The user also pushes the bead 12 on the other end side into the holding portion 8 a until the lower end of the bead 12 contacts the floor surface 21. Alternatively, both ends of the waterproof sheet 10 may be first held by the sheet guide 8 and then the waterproof sheet 10 may be temporarily fixed to the opening / closing body 7. In other words, the temporary fixing procedure may be executed after the procedure for holding one end of the sheet and the procedure for holding the other end of the sheet are executed.

  Here, after the procedure for holding the other end of the sheet is executed, an excessive portion 10a that sags in the waterproof sheet 10 may occur depending on the width of the opening 22 as shown in FIG. If the surplus portion 10a remains in the waterproof sheet 10, a gap is likely to be generated between the waterproof sheet 10 and the floor surface 21 or between the waterproof sheet 10 and the opening / closing body 7, and the waterproof sheet 10 has sufficient water stoppage. There is a possibility that it cannot be demonstrated. The installation method of the waterproof device according to the present embodiment includes a procedure (hereinafter simply referred to as “surplus part holding procedure”) for holding the excess portion 10a of the waterproof sheet 10 in a folded state, which will be described below. It is configured. In addition, although the surplus part holding | maintenance procedure demonstrated below is effective in order to improve a water stop performance more, if the water stop performance in a use purpose can be satisfied, the slack of the surplus part 10a is left to some extent or all. For example, all or part of the surplus part holding procedure may be omitted.

(E. Surplus part holding procedure)
The surplus part holding procedure is executed after the sheet setting procedure and before the placing procedure described later. The surplus part holding procedure is a procedure of holding the surplus portion 10a of the waterproof sheet 10 generated when the opening / closing body 7 is covered with the waterproof sheet 10 in a folded state. The surplus part holding procedure is a procedure for adjusting the installation width and the effective width of the waterproof sheet 10 according to the width of the opening 22 by folding the waterproof sheet 10. The installation width and the effective width are the lengths in the width direction of the portion of the waterproof sheet 10 installed so as to cover the opening / closing body 7 that directly covers the opening / closing body 7. In the waterproof sheet 10, if the length from the portion 10 b located at one end in the width direction of the opening 22 to the portion 10 c located at the other end is larger than the width W of the opening 22, an excess portion 10 a is generated. The width W of the opening 22 is, for example, the inner dimension of the pair of guide rails 9.

  The user pulls the waterproof sheet 10 in the width direction toward the surplus portion 10a so as to stretch the wrinkles and slack of the portion directly covering the opening / closing body 7. Thereafter, as shown in FIG. 12, the surplus portion 10 a is folded in half, and the surplus portion 10 a is overlapped with the portion directly covering the opening / closing body 7. When the surplus portion 10a is folded in half, it is preferable that the magnet 14 be positioned in the vicinity of the tip (mountain fold portion) of the surplus portion 10a. If it does in this way, as shown in FIG. 13, the front-end | tip of the surplus part 10a can be made to adsorb | suck to the opening / closing body 7 with the magnet 14, and it can suppress that the surplus part 10a floats from the opening / closing body 7.

In this case, the user may adjust the gap between the waterproof sheet 10 and the opening / closing body 7 and the guide rail 19 at the corners while shifting the waterproof sheet 10 in the width direction of the opening / closing body 7. Other adjustments can be the same as the adjustment procedure of the first embodiment.

(End folding procedure)
For the structure 50 to be installed in the second embodiment, the end folding procedure may be omitted in the waterproof device installation method.

(Installation procedure)
The placement procedure of the second embodiment will be described. In the case of the structure 50 targeted in the present embodiment, unlike the structure 20 of the first embodiment, the wall surface 23 that restricts the range in the width direction on which the pressing member 4 is placed does not exist. For this reason, it is possible to place the pressing member 4 continuously on a straight line. An example of a preferable placement procedure of the pressing member 4 will be described.

  As shown in FIG. 33, the user starts placing the pressing member 4 from one end side in the width direction. 33 to 36 show a case where the pressing members 4 are arranged from the left side to the right side in the drawing. As shown in FIG. 33 and FIG. 34, it is preferable that the pressing member 4 placed at the end in the width direction is placed so as to protrude from the skirt 10d of the waterproof sheet 10 onto the floor surface 21. In other words, it is preferable to place the pressing member 4 so as to protrude from the end of the opening 22 in the width direction of the waterproof sheet 10 on the floor 21. If it does in this way, it can suppress that the edge part of the width direction of the skirt part 10d floats with the press member 4, and can improve the water stop performance of the waterproof sheet 10. FIG. In addition, if the edge part of the width direction of the skirt part 10d can be pressed on the floor surface 21, even if the press member 4 does not protrude on the floor surface 21, the improvement of a water stop performance can be anticipated.

  The position where the pressing member 4 is placed is preferably a position where the plurality of pressing members 4 can be placed in a line in the width direction and close to the opening / closing body 7. For example, as shown in FIG. 33 and FIG. 34, if the pressing member 4 is placed close to the guide rail 19 or pressed against the guide rail 19, the water stoppage by the waterproof sheet 10 is achieved. An improvement in performance can be expected. In addition, the pressing member 4 is preferably placed at a position where the rubber sheet 13 is pressed toward the floor surface 21.

  As shown in FIG. 35, the user continuously places the pressing members 4 in order from one side in the width direction to the other side. The pressing member 4 is preferably placed so that the ends of the pressing members 4 adjacent to each other are brought into contact with each other. In the present embodiment, the plurality of pressing members 4 are placed at least from one end to the other end in the width direction with respect to the opening 22. As shown in FIG. 36, when the pressing member 4 is placed from one end to the other end in the width direction of the skirt portion 10d, the placing procedure ends. As shown in FIG. 36, it is preferable that the pressing members 4 at both ends protrude from the skirt 10d onto the floor surface 21, respectively. That is, in the mounting procedure of the second embodiment, it is preferable that at least a part of the pressing member 4 disposed at the end portion in the width direction protrudes in the width direction from the end portion of the opening 22.

[Third Embodiment]
A third embodiment will be described with reference to FIG. About 3rd Embodiment, the description which attaches | subjects the same code | symbol to the component which has the function similar to what was demonstrated by each said embodiment, and abbreviate | omits the description. In the waterproof device installation method of the first embodiment and the waterproof device installation method of the second embodiment, a member for fixing the reinforcing member 3 to the floor surface 21 is further installed on the floor surface 21 side in advance. You may comprise including the procedure to do. Here, a procedure for installing the female screw member 6 will be described. FIG. 37 is an explanatory diagram of a procedure for installing the female screw member of the third embodiment.

(I. Procedure for installing female screw member)
The procedure for installing the female screw member 6 is executed when the waterproof device 1-1 is introduced, and is a procedure executed in advance in preparation for installing the waterproof device 1-1. If the structure for fixing the reinforcing member 3 is not provided on the floor surface 21 side in advance, the following problems may occur.
(1) When installing the waterproof device 1-1, it is difficult for the user to appropriately determine the installation location of the reinforcing member 3.
(2) The number of steps required for the user to fix the reinforcing member 3 to the floor surface 21 is increased, and a long time is required for installation.
(3) The fixing strength for fixing the reinforcing member 3 to the floor surface 21 is insufficient, and there is a possibility that the opening / closing body 7 cannot be properly supported against water pressure.

  On the other hand, by providing a configuration for fixing the reinforcing member 3 in advance on the floor surface 21 side, the user can easily know the installation location of the reinforcing member 3. Further, the user can install the reinforcing member 3 with less man-hours. Further, by providing in advance a structure capable of ensuring the required strength on the floor surface 21 side, the reinforcing member 3 can appropriately support the opening / closing body 7 against water pressure.

  If it demonstrates with reference to FIG. 37, the procedure which installs the internal thread member 6 includes the procedure which forms the recessed part 26 for installation in the floor surface 21, and the procedure which fixes the internal thread member 6 to the said recessed part 26, for example. Composed.

(I-1. Procedure for forming recesses)
In the procedure for forming the recess, the recess 26 is formed on the floor surface 21. The inner diameter of the formed recess 26 is larger than the outer diameter of the female screw member 6. The recess 26 is formed by, for example, perforation. The arrangement of the recesses 26 is determined according to the position of the opening / closing body 7 when the opening / closing body 7 is fully closed. For example, the amount of deflection of the opening / closing body 7 when water pressure is applied is obtained by simulation or the like, and the opening / closing body 7 and the recess 26 are brought into contact with the reinforcing member 3 when a predetermined amount of water pressure is applied. The position of is determined.

  As for the position where the recess 26 is formed and the position where the reinforcing member 3 is installed, when the opening / closing body 7 closes, the reinforcing member 3 does not interfere with the opening / closing body 7 when closed. However, when the opening / closing body 7 is closed from the upper side to the lower side, for example, if the reinforcing member 3 interferes with a protruding portion in the thickness direction of the opening / closing body 7 (for example, a seat plate which is the lower end portion of the shutter curtain), The part where the member 3 interferes may be retracted from the opening / closing body 7 and may be configured to return to the original state when the protruding portion of the opening / closing body 7 passes. An example of a configuration in which the interfering part is retracted and returned is urged by the spring member so that the interfering part is always in the original state, and at the time of interference, the spring is pressed by the pressing force of the interfering part of the opening / closing body 7. The part where the reinforcing member 3 interferes against the biasing force of the member is retracted from the opening / closing body 7. In this configuration, the reinforcing member 3 is retracted when the opening / closing body 7 is supported against the water pressure, such as being retracted by the pressing force from above but not retracting by the pressing force from the side. It is set as the structure which avoids that.

(I-2. Procedure for fixing female screw member)
In the procedure of fixing the female screw member 6, the female screw member 6 is fixed to the formed recess 26. Examples of the fixing method include a method of filling the periphery of the female screw member 6 with a filler 27 such as concrete, mortar, or adhesive.

  Since the female screw member 6 is provided in advance and fixed to the floor surface 21 side, the user can easily and firmly fix the reinforcing member 3 to the floor surface 21 when installing the waterproof device 1-1. It becomes possible to do. Moreover, since there are few procedures for fixing the reinforcement member 3, the waterproof device 1-1 can be installed quickly.

[First Modification of Each Embodiment]
A first modification of the first to third embodiments will be described. In the installation method of the waterproof device according to the first to third embodiments, the procedure can be omitted as appropriate, or the order in which the procedure is executed can be changed as appropriate for the example illustrated in each of the embodiments. It is.

  For example, in each of the above embodiments, the surplus part holding procedure may be omitted. When the opening / closing body 7 is covered with the waterproof sheet 10 in the sheet installation procedure, when the excess portion 10a does not occur in the waterproof sheet 10, the excess portion holding procedure may be omitted.

  In the reinforcing member fixing procedure of each of the above embodiments, the reinforcing member 3 is fixed to the floor surface 21 by the mounting bolt 2 and the female screw member 6, but the reinforcing member 3 may be fixed by other members or methods.

  In each of the above embodiments, the reinforcement procedure can be executed at an arbitrary timing. The reinforcing procedure may be performed, for example, after execution of the placing procedure for placing the pressing member 4. That is, the user can execute the reinforcement procedure by moving to the indoor side after executing the procedure performed on the outdoor side of the opening / closing body 7 first.

[Second Modification of Each Embodiment]
In the installation method of the waterproof device according to each of the above embodiments, when the surplus portion holding procedure is executed, the surplus portion 10a may be folded with a knob portion provided in advance on the waterproof sheet 10. FIG. 38 is a view showing a waterproof sheet having a knob portion. The knob portion 10e is formed by bending a part of the sheet body 11. The knob portion 10e is configured by folding the sheet body 11 into a substantially U shape and welding the U-shaped tip portions 10f.
