(Configuration-Inundation prevention structure)
Next, the details of the configuration of the shutter 1 will be described. FIG. 2 is a cross-sectional view of the door of FIG. As shown in FIGS. 1 and 2, the shutter 1 has a gap between the left guide rail 14 and the left end of the shutter curtain 30 (hereinafter, “left side gap 32 ( Side clearance) ”, the clearance between the right guide rail 14 and the right end of the shutter curtain 30 (hereinafter referred to as“ right clearance 33 (side clearance) ”), and the floor of the building An infiltration prevention structure is provided for preventing water from entering through a gap between the surface and the lower end of the seat plate 31 (hereinafter referred to as “lower gap”). This inundation preventing structure includes a waterproof sheet 40, a side insertion member 50, a lower insertion member 60, and a pressing member 70. Below, this flooding prevention structure is demonstrated.

(Structure-Flood prevention structure-Waterproof sheet)
First, the waterproof sheet 40 will be described. The waterproof sheet 40 covers the left side gap 32 and the right side gap 33 in the fully closed state of the opening, thereby preventing water from entering from each of the left side gap 32 and the right side gap 33. It is a waterproof means. This waterproof sheet 40 is a substantially rectangular sheet-like body, and is configured using, for example, a known waterproof sheet (specifically, a waterproof sheet or the like made of nylon on the front side and made of polyurethane on the back side). ing.

  Here, regarding the size and arrangement of the waterproof sheet 40, at least the outer surface of the shutter curtain 30 (that is, the right-side gap 33 is covered by the waterproof sheet 40 in the fully closed state of the opening) (that is, The shutter curtain 30 is disposed so as to reach the left guide rail 14 from the outer side of the building in the shutter curtain 30, and is disposed so as to reach the right guide rail 14 from the outer surface of the shutter curtain 30. The area covered by the waterproof sheet 40 is set as shown below. Specifically, as shown in FIG. 1 and FIG. 2, in one vertical region, one end of the region extends from the floor of the building to the assumed water surface. It is set at a position reaching a predetermined distance (for example, 400 mm, etc.) upward from the floor of the building so as to be equal to or higher than the height (for example, 300 mm, etc.). Moreover, about the other edge part of the said area | region, the extension part of the waterproof sheet 40 is made to extend outside the building rather than the downward insertion member 60 inserted in the downward gap so that it may mention later. Is set at a position that reaches a predetermined distance (for example, 100 mm, etc.) from the opening 3 toward the outside of the building so as to be pressed downward by the water that has flowed onto the extended portion. Further, in the lateral region, as will be described later, a part of the waterproof sheet 40 can be inserted into each of the left side gap 32 and the right side gap 33 together with the side insertion member 50. It is set so as to be a region extending from the outer surface of the left guide rail 14 to the outer surface of the right guide rail 14. With such an arrangement, the left side gap 32 and the right side gap 33 can be covered with the waterproof sheet 40 in the fully closed state of the opening.

(Configuration-Flood prevention structure-Side plug member)
Next, the side insertion member 50 will be described. 3A and 3B are diagrams showing the side insertion member 50, where FIG. 3A is a plan view, FIG. 3B is a front view, and FIG. 3C is a rear view. 3A shows a state in which the waterproof sheet 40 is connected to the side insertion member 50, but the waterproof sheet 40 is omitted in FIGS. 3B and 3C. (The same applies to FIG. 4 described later and FIG. 6 described later). FIG. 4 is an enlarged view of a main part of the region C in FIG. FIG. 5 is a view showing a state in which the pressing portion 55 of the side insertion member 50 described later is deformed. The side insertion member 50 is inserted into each of the left side gap 32 and the right side gap 33 in the fully closed state of the opening. The reason why the side insertion member 50 is provided is as follows. That is, as a method of fixing the waterproof sheet 40, for example, a fixing member is attached to each of the lateral ends of the waterproof sheet 40, and a holding member is attached to each of the left wall 11 and the right wall 12 of the building with mounting screws. Thus, a method of fixing the waterproof sheet 40 to the holding member via a fixing member is conceivable. However, in this method, it is necessary to provide attachment holes for attaching the holding member in each of the left wall 11 and the right wall 12, and preparation for providing this attachment hole in each of the left wall 11 and the right wall 12. Since construction had to be done, there was a possibility that it would take time to install. Therefore, in order to solve this problem, a side insertion member 50 is provided. As shown in FIGS. 1 and 2, the side insertion member 50 is inserted into each of the left side gap 32 and the right side gap 33 when the opening is fully closed. As shown in FIGS. 2 and 3, the side insertion member 50 includes a main body portion 51 and a pressing portion 55.

(Structure-Inundation prevention structure-Side insertion member-Body part)
The main body 51 is a basic structure of the side insertion member 50. The main body 51 is formed of a solid body (however, as shown in FIG. 2, for the convenience of manufacturing, the main body 51 has a hollow portion 51a inside), and the opening is fully closed. In the state, at least a part of the main body 51 is inserted into the left side gap 32 or the right side gap 33. Hereinafter, of the end portions of the main body portion 51, the end portion 52 on the side inserted into the left side gap 32 or the right side gap 33 is referred to as a “side insertion end portion 52 (insertion end portion)”.

  Here, the shape of the main body 51 is arbitrary, but in the embodiment, the length (gap width) in the front-rear direction of the left-side gap 32 (or right-side gap 33) in the fully closed state of the opening. However, it is formed in a shape capable of adjusting the amount of insertion of the main body 51 in order to cope with the fact that it is not uniform depending on the installation status of the shutter 1 and the like.

  Specifically, as shown in FIG. 2 and FIG. 3A, the side insertion end portion 52 (specifically, the side insertion end portion 52 of the main body portion 51 is substantially omitted from the side insertion end portion 52). The cross-sectional shape of the portion reaching the center portion is formed in a wedge shape. In particular, with respect to the shape of the side insertion end portion 52, the length in the front-rear direction (gap width) of the left side gap 32 (or the right side gap 33) in the fully closed state of the opening is about 1 mm to 6 mm. In addition, the side insertion member 50 is preferably inserted into the left side gap 32 (or the right side gap 33) over the entire length of the left side gap 32 (or the right side gap 33) in the vertical direction. ing. More specifically, the lateral insertion end 52 has a lateral length (width) of about 40 mm (the lateral length (width) of the main body 51 is about 60 mm), and the lateral insertion end 52. The length (thickness) in the front-rear direction is about 1 mm to 6 mm (the length (thickness) in the front-rear direction of the end of the main body 51 opposite to the side insertion end is about 20 mm), and The length (height) in the vertical direction of the side insertion end 52 is formed to be about 400 mm (the same as the length (height) in the vertical direction of the main body 51). In the case of this shape, the inner angle formed by the front surface of the side insertion end portion 52 (the building outer surface in the front-rear direction) and the rear surface of the side insertion end portion 52 (the inner surface of the building in the front-rear direction) is 5 degrees to 10 degrees. It will be about. In addition, about the length (width | variety) of the left-right direction of this side insertion edge part 52, specifically, it is preferable to set so that it may become comparatively short. With such a shape, the insertion amount of the main body 51 is increased as the longitudinal length (gap width) of the left side gap 32 (or right side gap 33) in the fully closed state of the opening is increased. Therefore, the left side gap 32 (or the right side gap 33) can always be closed, so that the main body portion 51 can be used according to the length (gap width) of the left side gap 32 (or right side gap 33) in the front-rear direction. Therefore, the installation property of the side insertion member 50 can be improved.

  The setting of the inner angle formed by the front surface of the side insertion end portion 52 and the rear surface of the side insertion end portion 52 is arbitrary. For example, the length in the front-rear direction of the left side gap 32 (or the right side gap 33). When (the width of the gap) exceeds 1 mm to 6 mm, the inner angle formed by the front surface of the side insertion end portion 52 and the rear surface of the side insertion end portion 52 is larger than the inner angle shown in FIG. Alternatively, the length (thickness) in the front-rear direction and the length (width) in the left-right direction of the side insertion end 52 may be set while being substantially the same as the inner angle shown in FIG. May be longer than the length shown in FIG. When the length (thickness) in the front-rear direction of the left side gap 32 (or right side gap 33) is less than 1 mm to 6 mm, the front surface of the side insertion end portion 52 and the rear surface of the side insertion end portion 52 3 may be set to be smaller than the internal angle shown in FIG. 3 (a), or may be set to be substantially the same as the internal angle shown in FIG. You may make the length (thickness) of the front-back direction and the length (width) of the left-right direction shorter than the said length shown to Fig.3 (a).

  In addition, regarding the installation relationship between the main body 51 and the waterproof sheet 40, the main body 51 and the waterproof sheet 40 can be prevented from entering through the left side gap 32 (or the right side gap 33) in the fully closed state of the opening. A waterproof sheet 40 is installed. In the embodiment, as shown in FIG. 2, the waterproof sheet 40 is sandwiched between the left guide rail 14 and the side insertion end 52, and the side insertion end 52 and the outer surface of the shutter curtain 30. These side insertion end portions 52 and a part of the waterproof sheet 40 are inserted into the left side gap 32 so as to be sandwiched by the left side gap 32. Further, the lateral sheet 40 is sandwiched between the right guide rail 14 and the side insertion end 52 and is sandwiched between the side insertion end 52 and the outer surface of the shutter curtain 30. The insertion end 52 and a part of the waterproof sheet 40 are inserted into the right side gap 33. Further, in any one of these side insertion end portions 52 (in the embodiment, the side insertion end portion 52 inserted into the left side gap 32), as shown in FIG. Therefore, the waterproof sheet 40 is connected to the rear surface of the side insertion end 52 by a thread 58. The yarn 58 is made of, for example, a known yarn having durability or weather resistance (specifically, a chemical fiber yarn such as nylon yarn or polyester yarn, or a natural fiber yarn such as cotton tako yarn). In the rear surface of the side insertion end portion 52, the side insertion end portion 52 is continuously connected over the entire length in the vertical direction. In addition, a plurality of connecting portions by the thread 58 are arranged in parallel in the left-right direction at a predetermined interval (in the embodiment, two places are arranged in parallel). With such an installation relationship, the waterproof sheet 40 can be firmly held in the fully closed state of the opening, so that it is possible to prevent water from entering from the left side gap 32 and the right side gap 33. In particular, since the waterproof sheet 40 can be firmly held by the side insertion end portion 52 and the left (or right) guide rail 14, a gap between the left (or right) guide rail 14 and the waterproof sheet 40 is provided. Therefore, it is possible to further suppress water from entering.

  Further, the main body 51 is formed with a convex portion 53 and a notch portion 54. Among these, the convex part 53 is for making it difficult for the side insertion member 50 inserted in the left side gap 32 (or the right side gap 33) to be pulled out in the fully closed state of the opening. The convex portion 53 protrudes outward from a portion facing the left (or right) guide rail 14 through the waterproof sheet 40 in at least the outer surface of the side insertion end portion 52 in the main body portion 51. (For example, it protrudes about 1 mm), it is formed over the entire length of the main body 51 in the vertical direction, and a plurality of the main body portions 51 are arranged in parallel in the horizontal direction. Moreover, although the direction of installation of the convex portion 53 is arbitrary, in the embodiment, the side insertion member 50 and a part of the waterproof sheet 40 are partly left side gap 32 (or right side gap 33) by the convex portion 53. ), And the side insertion member 50 and a part of the waterproof sheet 40 are installed in a direction in which it is difficult to extract from the left side gap 32 (or the right side gap 33). As shown in FIG. 4, it is installed inclined toward the side opposite to the side inserted into the left side gap 32 (or right side gap 33). With such a convex portion 53, when the side insertion member 50 and a part of the waterproof sheet 40 are inserted into the left side gap 32 (or the right side gap 33) in the fully closed state of the opening, the convex portion 53 is located on these sides. Since it becomes difficult to resist a part of the side insertion member 50 and the waterproof sheet 40, a part of the side insertion member 50 and the waterproof sheet 40 can be easily inserted. On the other hand, when a part of the side insertion member 50 and the waterproof sheet 40 is extracted from the left side gap 32 (or the right side gap 33), the convex portion 53 becomes a part of the side insertion member 50 and the waterproof sheet 40. Since it resists with respect to this, it becomes difficult to extract a part of these side insertion member 50 and the waterproof sheet 40. From the above, it becomes possible to improve the installation property of the side insertion member 50 and the waterproof sheet 40.

  In addition, the notch 54 is configured so that the main body 51 and the seat plate cover 31a of the seat plate 31 when the side insertion member 50 is inserted into the left side gap 32 (or the right side gap 33) in the fully closed state of the opening. This is to avoid contact. As shown in FIGS. 3B and 3C, the notch 54 is formed in a portion corresponding to the seat plate cover 31 a in the lower end (or upper end) of the main body 51. As for the shape of the notch 54, specifically, the vertical length of the notch 54 is the upper and lower of the seat plate cover 31a so that the main body 51 can be prevented from contacting the seat plate cover 31a. The length (thickness) in the direction is set to be substantially the same as or longer than the length (thickness), and the length in the left-right direction of the notch 54 is substantially the same as the length (width) in the left-right direction of the seat plate cover 31a. It is set longer than that. With such a notch 54, the main body 51 comes into contact with the seat plate cover 31 a when the side insertion member 50 is inserted into the left side gap 32 (or the right side gap 33) in the fully closed state of the opening. Therefore, it is possible to improve the installation property of the side insertion member 50. In particular, since the cutout portion 54 is formed at the lower end portion and the upper end portion of the main body portion 51, even when the side insertion member 50 is inserted into either the left side gap 32 or the right side gap 33, the main body portion 51. Can be prevented from coming into contact with the seat plate cover 31a, and the installation property of the side insertion member 50 can be further enhanced.

(Configuration-Flood prevention structure-Side insertion member-Pressing part)
The pressing portion 55 presses at least a part of a portion of the waterproof sheet 40 covering the left (or right) guide rail 14 against the guide rail 14 by a restoring force generated by its own deformation (for example, bending deformation). Is. The reason why the pressing portion 55 is provided is as follows. That is, when the side insertion member 50 includes only the main body 51, the portion other than the portion inserted into the left side gap 32 in the portion covering the left guide rail 14 in the waterproof sheet 40 is inserted sideways. Since it is not clamped by the member 50 and the left guide rail 14, the portion other than the portion inserted into the left gap 32 is firmly fixed to the left guide rail 14 as compared to the portion inserted into the left gap 32. could not. For this reason, there is a possibility that water may enter from the gap between the waterproof sheet 40 and the left guide rail 14 (in the portion covering the right guide rail 14 in the waterproof sheet 40, the right gap 33 The same applies to the part other than the part inserted into the). Therefore, in order to solve this problem, a pressing portion 55 is provided. As shown in FIGS. 2 and 3, the pressing portion 55 is a substantially plate-like body, and is formed over the entire length of the main body portion 51 in the vertical direction. Further, the pressing portion 55 is arranged so as to protrude from the vicinity of the end portion of the outer surface of the main body portion 51 on the side opposite to the side insertion end portion 52 toward the side insertion end portion 52 side.

  Here, regarding the overhang length L <b> 1 of the pressing portion 55, in the embodiment, the distal end portion of the pressing portion 55 overlaps with the lateral insertion end portion 52 of the main body portion 51 from the viewpoint of manufacturability of the side insertion member 50. It is set to length. However, the present invention is not limited to this, and the distal end portion of the pressing portion 55 may be set to a length that projects outward from the lateral insertion end portion 52 of the main body portion 51, or the lateral insertion end portion of the main body portion 51. 52 may be set to a length that projects outward from the tip of the pressing portion 55.

  Further, although the installation relationship between the pressing portion 55 and the waterproof sheet 40 is arbitrary, in the embodiment, as shown in FIG. 2, the waterproof sheet 40 is in the front end portion of the pressing portion 55 in the fully closed state of the opening. The pressing portion 55 and the waterproof sheet 40 are installed so as to extend to the side. With such an installation relationship, in the fully closed state of the opening, the extended portion of the waterproof sheet 40 can be pressed by water, and from the gap between the left (or right) guide rail 14 and the waterproof sheet 40. It becomes possible to further suppress the intrusion of water. In addition, about the length L2 of the extension part of this waterproof sheet 40, specifically, this extension part turns up by flowing water, and this extension part and the guide rail 14 of the left side (or right side) are between. It is set to about 10 mm to 20 mm so that water can be prevented from entering from the gap between them.

  In addition, a contact portion 56 is provided at the tip of the pressing portion 55. The contact portion 56 is a contact means for bringing the pressing portion 55 into contact with the main body 51, and is formed so as to protrude toward the opposite side of the pressing portion 55 (for example, 5 mm). Projecting to some extent). Specifically, the contact between the pressing portion 55 and the main body 51 by the abutting portion 56 is deformed so that at least the distal end portion of the pressing portion 55 moves away from the main body 51 as shown in FIG. After that, in the state where it is further deformed toward the end of the main body 51 opposite to the side insertion end 52, only the front end portion of the abutting portion 56 is deformed toward the side insertion end 52 of the main body 51. The pressing portion 55 and the main body 51 are brought into contact with each other. In the case where the contact state between the pressing portion 55 and the main body portion 51 is maintained, for example, the pressing portion 55 can be held by pressing the contact portion 56 against the main body portion 51 with a user's finger. Such a contact portion 56 prevents the pressing portion 55 from interfering when the side insertion member 50 is inserted into the left side gap 32 (or the right side gap 33). Installation can be maintained. In particular, since the contact portion 56 is provided so as to protrude from the pressing portion 55, the contact portion 56 can be easily brought into contact with the main body portion 51.

  Moreover, although this press part 55 can be manufactured with arbitrary materials, in embodiment, it has water resistance, and it can press the waterproof sheet 40 with the restoring force which arises by self bending deformation. For example, it is made of a material having a lower altitude than the main body 51 (for example, a resin material such as rubber).

  By such a pressing portion 55, in a portion covering the left guide rail 14 in the waterproof sheet 40 in the fully closed state of the opening, a portion other than a portion inserted into the left side gap 32 (or a right side in the waterproof sheet 40 Of the portion covering the guide rail 14, the portion other than the portion inserted into the right-side gap 33) can be pressed against the guide rail 14, so that water flows from the gap between the guide rail 14 and the waterproof sheet 40. It is possible to further suppress the intrusion.

(Structure-Inundation prevention structure-Lower insertion member)
The lower insertion member 60 is inserted into the lower gap in the fully closed state of the opening. The reason why the lower insertion member 60 is provided is as follows. That is, it may be possible to prevent the waterproof sheet 40 from being turned up by running water by pressing the waterproof sheet 40 against the floor surface of the building only with the pressing member 70. However, in this case, as the flow of running water becomes stronger, it is necessary to increase the weight of the pressing member 70, which may reduce the installation property of the inundation prevention structure. Therefore, in order to solve this problem, a lower insertion member 60 is provided. The lower insertion member 60 is formed of, for example, a block-shaped body made of a resin such as rubber. As shown in FIGS. 1 and 2, the lower insertion member 60 is a lower portion in the fully closed state of the opening. A plurality of plugs are inserted into the gaps (specifically, they are inserted between the lower insertion members 60 with no gaps except for a part).

  Further, although the shape of the lower insertion member 60 is arbitrary, a portion into which the lower insertion member 60 is inserted (hereinafter referred to as a “lower insertion end”) in the fully closed state of the opening is a lower gap. It is formed in a shape that can be inserted. Specifically, the vertical length (thickness) of the lower insertion end is shorter at the tip than the vertical length (gap height) of the lower gap and the rear end. The portions are formed so as to be substantially the same. Further, the length (width) of the lower insertion end in the left-right direction is formed to be shorter than the length of the lower gap in the left-right direction (width of the gap).

  In addition, regarding the installation relationship between the lower insertion member 60 and the waterproof sheet 40, the lower insertion member 60 and the waterproof sheet 40 can be prevented from entering the lower gap in the fully closed state of the opening. Is installed. In the embodiment, the lower insertion end and a part of the waterproof sheet 40 are inserted into the lower gap so that the waterproof sheet 40 is sandwiched between the lower insertion end and the floor surface of the building. . With such a downward insertion member 60, the waterproof sheet 40 can be firmly held in the fully closed state of the opening, so that it is possible to prevent water from entering from the lower gap.

(Structure-Inundation prevention structure-Pressing member)
The pressing member 70 is for pressing the waterproof sheet 40. The reason why the pressing member 70 is provided is as follows. That is, since there are shutters of various widths, it is conceivable to form different lower insertion members 60 according to the respective widths. It is more preferable to form the lower insertion member 60 so that it can be done. Therefore, in the embodiment, two types of lower insertion members 60 (for example, a lower insertion member 60 having a width of about 300 mm and a lower insertion member having a width of about 600 mm) having different lengths (widths) in the left-right direction. 60, etc.) are combined in a number corresponding to the width of the shutter 1, so that the plurality of lower insertion members 60 are inserted into the lower gap without any gaps. At this time, any one of the two types of lower insertion members 70 having the width may be preferentially inserted. However, in this case, as long as the width of the shutter 1 is not the same as the total width of the combined lower insertion members 60, a surplus portion of the lower gap that cannot be filled with the plurality of lower insertion members 60 (specifically It is conceivable that a surplus portion in which the length (width) in the left-right direction is shorter than the length (width) in the left-right direction of the lower insertion member 60 having a short width is generated. In order to solve this problem, a pressing member 70 is provided.

  The pressing member 70 is formed of, for example, a thick plate (or rod) made of metal such as stainless steel (or resin coated metal). Moreover, about the width | variety of this press member 70, among the two types of lower insertion members 60, the width | variety of the lower insertion member 60 with a short width | variety can respond | correspond to the length (width) of the left-right direction of various excess parts. The width is set to be slightly longer than the width. Specifically, when the width of the lower insertion member 60 having the shorter width is about 300 mm, the width is set to about 350 mm. And as shown to FIG. 1 (a), FIG.1 (b), this press member 70 is a part of the said surplus part among the parts which oppose the floor surface of a building in the waterproof sheet 40 in an opening part fully closed state. It is mounted in the vicinity part (for example, the position of the outer side of a building rather than the downward insertion member 60). For example, when the width of the shutter 1 is 2900 mm, the width of the lower insertion member 60 is 600 mm, and the width of the lower insertion member 60 is 300 mm, the four lower insertion members 60 having the longer width are used. And the one lower insertion member 60 with the said short width | variety is arrange | positioned without a gap mutually, respectively, and the pressing member 70 is mounted in the vicinity part of this surplus part. At this time, since the pressing member 70 is preferably not disposed at the left end portion or the right end portion of the lower gap, the lower insertion member is provided so that an excessive portion (width = 200 mm) does not occur at the left end portion or the right end portion of the lower gap. 60 is arranged. Since the pressing member 70 can press the portion corresponding to the surplus portion of the waterproof sheet 40 even when the surplus portion occurs in the lower gap in the fully closed state of the opening, the waterproof sheet 40 and the floor surface of the building It becomes possible to further suppress the intrusion of water from the gap between them.

  With the above-described infiltration prevention structure, water can be prevented from entering from the left side gap 32 and the right side gap 33 in the fully closed state of the opening. In particular, compared with the prior art, the side insertion member 50 can be attached to the shutter 1 without performing preparatory work, so that it is possible to reduce the labor of installation work. As shown in FIGS. 1 and 2, in addition to a part of the waterproof sheet 40 being sandwiched between the side insertion member 50 and the left (or right) guide rail 14, the lower insertion member 60. The portion of the waterproof sheet 40 that faces the floor of the building is sandwiched by the vicinity of the lower end portion of the left (or right) guide rail 14, thereby further strengthening the waterproof sheet 40. Therefore, it is possible to further suppress the intrusion of water from the gap between the guide rail 14 and the waterproof sheet 40.

(Configuration-Installation method of water-inhibiting structure)
Next, a method for attaching the inundation preventing structure will be described.

  First, the shutter curtain 30 is moved so that the opening is fully closed. Next, the side insertion member 50 connected to the waterproof sheet 40 and a part of the waterproof sheet 40 are directed from the center side in the width direction (that is, the left-right direction) of the opening 3 toward the left guide rail 14 side. By inserting the sheet into the left side gap 32, the waterproof sheet 40 is sandwiched between the guide rail 14 and the side insertion end 52, and is sandwiched between the side insertion end 52 and the outer surface of the shutter curtain 30. In this case, the side insertion member 50 is inserted to such an extent that the side insertion member 50 does not wobble. At this time, the lower end portion of the side insertion member 50 is brought into contact with the floor surface of the building. In addition, before inserting the side insertion member 50, the pressing portion 55 is deformed in a direction away from the main body portion 51, and then the end of the main body portion 51 opposite to the side insertion end portion 52. The contact portion 56 is brought into contact with the end portion of the main body portion 51 opposite to the side insertion end portion 52 in a state where the pressing portion 55 and the main body portion 51 are Abut. And after inserting this side insertion member 50, among the parts which cover the left guide rail 14 in the waterproof sheet 40 by the deformed pressing part 55, a part other than the part inserted into the left side gap 32 is the guide. The rail 14 is pressed (the same applies to the side insertion members 50 that are not connected to the waterproof sheet 40). In this way, by disposing one side insertion member 50, the waterproof sheet 40 can be disposed so that the left side gap 32 is covered by the waterproof sheet 40.

  Next, the side insertion member 50 that is not connected to the waterproof sheet 40 and a part of the waterproof sheet 40 are inserted into the right gap 33 from the center in the width direction of the opening 3 toward the right guide rail 14. As a result, the waterproof sheet 40 is sandwiched between the guide rail 14 and the side insertion end 52, and is sandwiched between the side insertion end 52 and the outer surface of the shutter curtain 30. At this time, the lower end portion of the side insertion member 50 is brought into contact with the floor surface of the building. Thus, by arranging the other side insertion member 50, the waterproof sheet 40 can be arranged so that the right side gap 33 is covered by the waterproof sheet 40.

  Subsequently, the plurality of lower insertion members 60 and a part of the waterproof sheet 40 are inserted into the lower gap from the outside to the inside of the building. And the press member 70 is mounted in the vicinity part of the said surplus part among the parts which oppose the floor surface of the building in the waterproof sheet 40. FIG. In this case, among the plurality of lower insertion members 60, the leftmost lower insertion member 60 is brought into contact with the lateral insertion member 50 connected to the waterproof sheet 40, and the rightmost lower insertion member 60. The side insertion member 60 is brought into contact with the side insertion member 50 that is not connected to the waterproof sheet 40. This completes the installation of the flood prevention structure.

  In addition, when removing a water immersion prevention structure, the press member 70 is removed from the waterproof sheet 40 first. Next, the side insertion member 50 to which the waterproof sheet 40 is not connected is removed from the right side gap 33. Next, the plurality of lower insertion members 60 are removed from the waterproof sheet 40. In this case, when the lower insertion member 60 is inserted relatively firmly, the plurality of lower insertion members 60 may be removed after the shutter curtain 30 is moved upward. Then, the side insertion member 50 to which the waterproof sheet 40 is connected is removed from the left side gap 32.

Thus, according to the embodiment, at least the lateral insertion end 52 of the lateral insertion member 50 has a wedge shape, and the waterproof sheet 40 is in the left guide in the fully closed state of the opening. The side insertion end 52 and a part of the waterproof sheet 40 are inserted into the left side gap 32 so that the rail 14 and the side insertion end 52 are sandwiched, and the waterproof sheet 40 is connected to the right guide rail 14. Part of the side insertion end 52 and the waterproof sheet 40 are inserted into the right side gap 33 so as to be sandwiched by the side insertion end 52 and the side insertion end 52. Water can be prevented from entering from the side gap 32 and the right side gap 33. In particular, compared with the prior art, the side insertion member 50 can be attached to the shutter 1 without performing preparatory work, so that it is possible to reduce the labor of installation work.

  Moreover, since the side insertion member 50 includes a pressing portion 55 that presses at least a part of the waterproof sheet 40 covering the left (or right) guide rail 14 against the guide rail 14, the opening is fully closed. In the state, at least a part of the portion of the waterproof sheet 40 covering the left (or right) guide rail 14 can be pressed against the guide rail 14, and from the gap between the guide rail 14 and the waterproof sheet 40. It becomes possible to further suppress the intrusion of water.

  Further, at the distal end portion of the pressing portion 55, at least the distal end portion of the pressing portion 55 is deformed toward the direction away from the side insertion member 50, and then the side insertion end portion of the side insertion member 50 is further removed. The contact portion for contacting the pressing portion 55 to the end of the side insertion member 50 opposite to the side insertion end 52 in a state of being deformed toward the end opposite to the end 52. 56, when the side insertion member 50 is inserted into the left side gap 32 or the right side gap 33, the abutting portion 56 is the end of the side insertion member 50 opposite to the side insertion end 52. , It is possible to prevent the pressing portion 55 from interfering with each other and maintain the installation property of the side insertion member 50.

  Further, in the fully closed state of the opening, the waterproof sheet 40 is extended laterally from the tip of the pressing portion 55 in the side insertion member 50 inserted into the left side gap 32 or the right side gap 33. The extended portion of the waterproof sheet 40 can be pressed by water, and water can be further prevented from entering from a gap between the left (or right) guide rail 14 and the waterproof sheet 40. .

  Further, at least the side insertion end portion 52 of the side insertion member 50 has a left side gap 32 or a right side gap 33 in a portion facing the left (or right) guide rail 14 via the waterproof sheet 40. Since the convex part 53 which inclines and protrudes toward the opposite side to the side to be inserted is provided, in the fully closed state of the opening part, the side insertion member 50 and a part of the waterproof sheet 40 are placed on the left side gap 32 or the right side. When inserting into the gap 33, the convex portion 53 becomes difficult to resist a part of the side insertion member 50 and the waterproof sheet 40, so that the side insertion member 50 and a part of the waterproof sheet 40 are easily inserted. . On the other hand, when extracting a part of the side insertion member 50 and the waterproof sheet 40 from the left side gap 32 or the right side gap 33, the convex portion 53 is formed with respect to the side insertion member 50 and a part of the waterproof sheet 40. Since it resists, a part of these side insertion member 50 and the waterproof sheet 40 becomes difficult to extract. From the above, it becomes possible to improve the installation property of the side insertion member 50 and the waterproof sheet 40.

Moreover, since the downward insertion member 60 for inserting in the downward gap toward the inside of the said building from the outer side of the building was provided, the floor of the building in the waterproof sheet 40 is formed by the lower insertion member 60 and the floor surface of the building. Of the portions facing the surface, the vicinity of the lower end portion of the left (or right) guide rail 14 is sandwiched so that the waterproof sheet 40 can be held more firmly, so that the guide rail 14 and the waterproof sheet 40 It is possible to further suppress the intrusion of water from the gap between them.
