Description

  The present invention relates to a flood prevention structure.

  2. Description of the Related Art Conventionally, an inundation preventing structure for preventing inundation from around a shutter curtain that opens and closes an opening provided in a building wall has been proposed. For example, such a flood prevention structure can prevent water from entering from the gap between the vertical frame provided at the periphery of the opening and the side of the shutter curtain so that the water can enter the outdoor side of the shutter curtain. In addition, a waterproof sheet is provided on the side surface, and a seal member is provided on the guide rail installed on the side of the opening so as to face the waterproof sheet. According to this water immersion prevention structure, when the water pressure is applied to the shutter curtain, the waterproof sheet is pressed against the sealing material, so that water from the side of the shutter curtain can be prevented.

  However, in such an inundation prevention structure, water can be prevented from entering through the gap between the vertical frame and the side of the shutter curtain, but between the floor of the building and the lower end of the shutter curtain. There was still a risk of water intrusion from the gap. Therefore, in order to solve such a problem, an inundation preventing structure that closes the gap between the floor surface of the building and the lower end of the shutter curtain has been proposed (for example, see Patent Document 1). This inundation prevention structure is a waterproof sheet provided so as to be located on the outdoor side of the shutter curtain, covers the range from the lower part of the shutter curtain to the floor of the building, and the end of the waterproof sheet Is provided with a waterproof sheet arranged so as to extend toward the outdoor side along the floor of the building. Moreover, in order to prevent a waterproof sheet from turning up by flowing water, the press member is mounted in the edge part of a waterproof sheet. With such a configuration, the waterproof sheet is pressed against the floor of the building by the pressing member, whereby the waterproof sheet can be prevented from being turned up by running water. Therefore, since the gap between the floor of the building and the lower end of the shutter curtain can be closed, water can be prevented from entering through this gap.

(Configuration-Inundation prevention structure)
Next, the details of the configuration of the shutter 1 will be described. FIG. 3 is an enlarged view of a lower region of FIG. As shown in FIGS. 2 and 3, the shutter 1 has a gap 32 (hereinafter referred to as a “lower gap 32”) between the floor of the building and the lower end of the seat plate 31 in the fully closed state of the opening. ), A gap 33 between the left guide rail 14 and the left end of the shutter curtain 30 (hereinafter referred to as “left gap 33 (side gap)”), and the right guide rail 14 and the shutter curtain 30. A water intrusion prevention structure is provided for preventing water from entering through a gap 34 between the right end and the right side end (hereinafter referred to as “right side gap 34 (side gap)”). This water immersion prevention structure includes a waterproof sheet 60, a lower insertion member 70, a side insertion member 80, and a pressing member 90. Below, this flooding prevention structure is demonstrated.

(Structure-Flood prevention structure-Waterproof sheet)
First, the waterproof sheet 60 will be described. The waterproof sheet 60 is waterproof means for preventing water from entering from the lower gap 32 by covering the lower gap 32 in the fully closed state of the opening. The waterproof sheet 60 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, the size and arrangement position of the waterproof sheet 60 are arbitrary, but at least the outer surface of the shutter curtain 30 (that is, the shutter curtain) so that the lower gap 32 is covered by the waterproof sheet 60 in the fully closed state of the opening. 30 to the floor of the building. The area covered by the waterproof sheet 60 is set as shown below. Specifically, as shown in FIGS. 1 to 3, in the vertical region, for one end of the 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 L1 (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, extending the waterproof sheet 60 by making the waterproof sheet 60 extend outside the building rather than the lower insertion member 70 inserted into the lower gap 32, as will be described later. It is set at a position that reaches a predetermined distance L2 (for example, 100 mm, etc.) from the opening 3 toward the outside of the building so that the portion is pressed downward by the water that has flowed onto the extended portion. Further, in the lateral region, as described later, a part of the waterproof sheet 60 can be inserted into each of the left side gap 33 and the right side gap 34 together with the side insertion member 80. 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 lower gap 32 can be covered with the waterproof sheet 60 in the fully closed state of the opening.

(Structure-Inundation prevention structure-Lower insertion member)
Next, the lower insertion member 70 will be described. 4A and 4B are views showing the lower insertion member 70, where FIG. 4A is a plan view, FIG. 4B is a rear view, FIG. 4C is a bottom view, and FIG. It is CC sectional view taken on the line. The lower insertion member 70 is for inserting into the lower gap 32 in the fully closed state of the opening. The reason why the lower insertion member 70 is provided is as follows. That is, it may be possible to prevent the waterproof sheet 60 from being turned up by running water by pressing the waterproof sheet 60 against the floor surface of the building only by the pressing member 90. However, in this case, as the flow of flowing water becomes stronger, it is necessary to increase the weight of the pressing member 90, so that there is a possibility that the installation property of the inundation preventing structure may be lowered. Therefore, in order to solve this problem, a lower insertion member 70 is provided. As shown in FIGS. 1 and 2, a plurality of lower insertion members 70 are inserted in the lower gap 32 along the left-right direction in the fully closed state of the opening. More specifically, a plurality of lower insertion members 70 are inserted with no gap between them except for a part. Since the plurality of lower insertion members 70 can be configured identically to each other, a single lower insertion member 70 will be representatively described below. As shown in FIGS. 3 and 4, the lower insertion member 70 includes a main body portion 71 and a close contact portion 75.

(Configuration-Inundation prevention structure-Lower insertion member-Main body)
The main body 71 is a basic structure of the lower insertion member 70. The main body 71 is formed of a solid body (or a hollow body), and at least a part of the main body 71 is inserted into the lower gap 32 when the opening is fully closed. Hereinafter, of the end portions of the main body portion 71, the end portion 72 on the side inserted into the lower gap 32 is referred to as a “lower insertion end portion 72 (insertion end portion)”.

  Here, the shape of the main body 71 is arbitrary, but in the first embodiment, the length of the lower gap 32 in the fully closed state of the opening (the height of the gap) is determined by the installation of the shutter 1. In order to cope with the fact that it is not uniform depending on the situation or the like, the main body 71 is formed in a shape that can adjust the amount of insertion. The vertical length of the lower gap 32 (height of the gap) is normally about 0 mm, but here, the lower gap 32 is formed by lifting the seat plate 31 upward. It will be described as the length of time.

  Specifically, as shown in FIGS. 3 and 4 (d), the longitudinal section of the entire main body 71 is formed in a wedge shape. More specifically, when the length of the lower gap 32 in the fully closed state of the opening (height of the gap) is about 1 mm to 10 mm, the lower insertion member 70 is preferably inserted into the lower gap 32. The length (width) of the main body 71 is about 300 mm to 600 mm, the length (depth) of the main body 71 is about 70 mm to 80 mm, and the vertical direction of the main body 71 so that it can be inserted. The length (thickness) is about 10 mm to 20 mm. In the case of this shape, the inner angle formed by the upper surface of the main body 71 and the lower surface of the main body 71 is about 10 degrees to 15 degrees. With such a shape, the lower gap 32 is always kept by increasing the amount of insertion of the main body 71 as the vertical length (gap height) of the lower gap 32 in the fully closed state of the opening increases. Since it can be closed, the amount of insertion of the main body 71 can be adjusted according to the length of the lower gap 32 in the vertical direction (height of the gap), and the installation property of the lower insertion member 70 can be improved. It becomes possible.

  The setting of the inner angle formed by the upper surface of the main body 71 and the lower surface of the main body 71 is arbitrary. For example, when the length of the lower gap 32 in the vertical direction (height of the gap) exceeds 1 mm to 10 mm. The internal angle formed by the upper surface of the main body 71 and the lower surface of the main body 71 may be set larger than the internal angle shown in FIG. 4D, or substantially the same as the internal angle shown in FIG. While setting the same, the length (thickness) in the vertical direction and the length (depth) in the front-rear direction of the main body 71 may be longer than the length shown in FIG. In addition, when the vertical length of the lower gap 32 (height of the gap) is less than 1 mm to 10 mm, the inner angle formed by the upper surface of the main body 71 and the lower surface of the main body 71 is shown in FIG. The length (thickness) in the vertical direction and the length (depth) in the front-rear direction of the main body 71 may be set while being set to be substantially the same as the internal angle. It may be shorter than the length shown in (d).

  Further, when the length (depth) of the main body portion 71 in the front-rear direction is made shorter than the predetermined distance L2, the lower insertion member 70 is inserted into the lower gap 32 in the fully closed state of the opening. The waterproof sheet 60 can be extended to the outside of the building rather than the lower insertion member 70 inserted into the lower gap 32. In this state, the extension portion of the waterproof sheet 60 is pressed downward by the water that has flowed onto the extension portion, so that water enters from the gap between the floor of the building and the waterproof sheet 60. This can be further suppressed.

  In addition, regarding the installation relationship between the main body 71 and the waterproof sheet 60, the main body 71 and the waterproof sheet 60 are installed so that water can be prevented from entering through the lower gap 32 in the fully closed state of the opening. Yes. In the first embodiment, as shown in FIGS. 2 and 3, the waterproof sheet 60 is sandwiched between the lower end portion of the seat plate 31 and the lower insertion end portion 72 of the main body portion 71, and this lower insertion portion is inserted. The lower insertion end 72 and a part of the waterproof sheet 60 are inserted into the lower gap 32 so as to be sandwiched between the end 72 and the floor of the building. With such an installation relationship, the waterproof sheet 60 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 32. In particular, since the waterproof sheet 60 can be firmly held by the lower insertion end portion 72 and the floor surface of the building, water can be prevented from entering from the gap between the floor surface of the building and the waterproof sheet 60. Is possible.

  Further, the main body portion 71 is formed with a first notch portion 73 (notch portion) and a second notch portion 74. Among these, the 1st notch part 73 is for aiming at a user's finger | toe or weight reduction of the lower insertion member 70, when a user holds the lower insertion member 70. FIG. The first notch 73 is formed over the entire length of the main body 71 in the left-right direction at the end of the main body 71 opposite to the lower insertion end 72. In addition, the vertical cross-sectional shape of the first cutout portion 73 is arbitrary, but in the first embodiment, the first cutout portion 73 is formed in a semicircular shape so that the user's finger is easily applied to the first cutout portion 73. (Or the present invention is not limited to this, and may be formed in a rectangular shape or a triangular shape). Such a first cutout portion 73 allows a finger to be put on the first cutout portion 73, allowing the lower insertion member 70 to be easily inserted into a predetermined position, and providing the first cutout portion 73. Compared with the case where it is not, the weight of the lower insertion member 70 can be reduced, and the manufacturing cost can be reduced.

  The second notch 74 is formed to form a space 74 a (hereinafter referred to as “accommodating space 74 a”) that accommodates the close contact portion 75. The second notch 74 is formed on the lower surface of the main body 71 over the entire length of the main body 71 in the left-right direction. Further, the vertical cross-sectional shape of the second notch 74 is arbitrary, but in the first embodiment, it is formed in a trapezoidal shape (or not limited to this, but in a triangular shape, semicircular shape, or rectangular shape). May be formed). Further, although the arrangement of the second cutout portion 74 is arbitrary, in the first embodiment, it is difficult for the lower insertion member 70 to be inserted by the contact portion 75 accommodated in the second cutout portion 74 or the accommodation space 74a. It is arrange | positioned in the edge part side on the opposite side to the downward insertion edge part 72 in the lower surface of the main-body part 71 so that it can suppress. Since the accommodation space 74a can be formed by such a second cutout portion 74, the close contact portion 75 can be accommodated in the accommodation space 74a.

  The main body 71 can be made of any material, but in the first embodiment, it is made of a material that is excellent in water resistance and hardly deforms (for example, a resin material such as rubber). ing.

The contact portion 75 is a portion that allows a part of the waterproof sheet 60 to be in close contact with the floor surface of the building. The reason why the contact portion 75 is provided is as follows. That is, when the lower insertion member 70 includes only the main body portion 71, the main body portion is more uneven when the shape of the floor surface of the building is uneven than when the shape of the floor surface of the building is flat. Since it becomes difficult for the part 71 and the floor surface of the building to be in close contact with each other, there is a possibility that water may enter from a gap between the floor surface of the building and the waterproof sheet 60. Therefore, in order to solve this problem, a close contact portion 75 is provided. The contact portion 75 is a hollow tubular body (or may be a solid body), and is formed over the entire length of the main body portion 71 in the left-right direction. Further, the contact portion 75 is accommodated in the accommodation space 74a of the main body portion 71. Specifically, the contact portion 75 can be reliably brought into contact with the floor surface of the building via the waterproof sheet 60. A part of the close contact portion 75 is accommodated so as to protrude downward from the accommodation space 74a. In this case, the shape relationship between the contact portion 75 and the second notch 74 is arbitrary, but in the first embodiment, the lower insertion member 70 is inserted into the lower gap 32 in the fully closed state of the opening. Thus, when the close contact portion 75 is pressed and deformed by being pressed by the main body portion 71, the close contact portion 75 and the second notch portion are prevented so that the press deformed close contact portion 75 does not protrude from the accommodation space 74a. 74 shapes are set. Thereby, even if the close contact portion 75 is pressed and deformed, the press deformed close contact portion 75 can be prevented from protruding from the accommodation space 74a, so that the main body portion 71 can be stably supported with respect to the floor surface of the building. It becomes possible.

  Moreover, although this contact | adherence part 75 can be manufactured with arbitrary materials, in Embodiment 1, it has water resistance and makes the restoring force which arises by self press deformation act on a part of waterproof sheet 60. Thus, a part of the waterproof sheet 60 can be brought into close contact with the floor surface of the building, and is manufactured with a material that can be deformed according to the surface shape of the floor surface of the building. The contact portion 75 is made of a material whose hardness is lower than that of the main body portion 71.

  With such a close contact portion 75, when the lower insertion member 70 is inserted into the lower gap 32 in the fully closed state of the opening, the close contact portion 75 allows a part of the waterproof sheet 60 to be in close contact with the floor surface of the building. Since it can do, it becomes possible to suppress that water permeates from the gap between the floor of the building and the waterproof sheet 60. In particular, regardless of the surface shape of the floor surface of the building, a part of the waterproof sheet 60 and the floor surface of the building can be brought into close contact with each other by a close contact portion 75 in a predetermined region. It is possible to further suppress the intrusion of water from the gaps between the two.

(Configuration-Flood prevention structure-Side plug member)
The side insertion member 80 is inserted into each of the left side gap 33 and the right side gap 34 in the fully closed state of the opening. The reason why the side insertion member 80 is provided is as follows. That is, as a method of fixing the waterproof sheet 60, for example, a fixing member is attached to each of the lateral ends of the waterproof sheet 60, and a holding member is attached to each of the left wall 11 and the right wall 12 of the building with an attaching screw. Thus, a method of fixing the waterproof sheet 60 to the holding member via the fixing member can be considered. 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 80 is provided. The side insertion member 80 is formed of a resin block such as rubber, for example. As shown in FIGS. 1 and 2, the left side gap 33 and the right side gap are opened in the fully closed state of the opening. 34 is inserted in each.

  Further, although the shape of the side insertion member 80 is arbitrary, a portion into which the side insertion member 80 is inserted (hereinafter referred to as “side insertion end”) in the fully closed state of the opening is a left side gap. 33 (or right side gap 34) is formed in a shape that can be inserted without a gap. Specifically, the length (thickness) in the front-rear direction of the side insertion end is the tip of the left-side gap 33 (or right-side gap 34) in the front-rear direction (gap width). The part is formed to be shorter and the rear end part thereof to be substantially the same or longer. Moreover, the length (height) of the side insertion end in the vertical direction is formed to be substantially the same as the length from the upper end of the waterproof sheet 60 to the floor of the building.

  In addition, regarding the installation relationship between the side insertion member 80 and the waterproof sheet 60, in order to prevent water from entering from the left side gap 33 (or the right side gap 34) in the fully closed state of the opening, The direction insertion member 80 and the waterproof sheet 60 are installed. In the first embodiment, the side insertion end portion and a part of the waterproof sheet 60 are part of the left side gap 33 so that the waterproof sheet 60 is sandwiched between the left guide rail 14 and the side insertion end portion. Plugged in. Further, the side insertion end part and a part of the waterproof sheet 60 are inserted into the right side gap 34 so that the waterproof sheet 60 is sandwiched between the right guide rail 14 and the side insertion end part. Moreover, in either one of these side insertion end parts (in the embodiment, the side insertion end part inserted into the left side gap 33), for example, in order to improve the installation property, A waterproof sheet 60 is connected by a thread to the rear surface (the inner surface of the building in the front-rear direction). This yarn is composed of, for example, a known yarn having durability or weather resistance (chemical fiber yarn such as nylon yarn or polyester yarn, natural fiber yarn such as cotton tako yarn), and lateral insertion. On the rear face of the end portion, the side insertion end portion is connected over the entire length in the vertical direction. In addition, a plurality of connecting portions by the yarn are arranged in parallel along the left-right direction at a predetermined interval.

  Such a side insertion member 80 can firmly hold the waterproof sheet 60 in the fully closed state of the opening, so that it is possible to prevent water from entering from the left side gap 33 and the right side gap 34. .

(Structure-Inundation prevention structure-Pressing member)
The pressing member 90 is for pressing the waterproof sheet 60. The reason why the pressing member 90 is provided is as follows. That is, since there are shutters of various widths, it is conceivable to form different lower insertion members 70 according to the widths. It is more preferable to form the lower insertion member 70 so that it can be performed. Therefore, in the first embodiment, two types of lower insertion members 70 having different lengths (widths) in the left-right direction (for example, a lower insertion member 70 having a width of about 300 mm and a lower insertion member having a width of about 600 mm). The members 70 and the like are combined in the number corresponding to the width of the shutter 1 so that the plurality of lower insertion members 70 are inserted into the lower gap 32 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 70, an excess portion of the lower gap 32 that cannot be filled with the plurality of lower insertion members 70 (specifically Specifically, there may be a case where 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 70 having a short width is generated. In order to solve this problem, a pressing member 90 is provided.

  The pressing member 90 is formed of, for example, a thick plate-shaped body (or rod-shaped body) made of metal such as stainless steel (or resin-coated metal). Moreover, about the width | variety of this press member 90, among the two types of lower insertion members 70, the width | variety of the lower insertion member 70 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 70 having the shorter width is about 300 mm, the width is set to about 350 mm. And as shown to Fig.1 (a) and FIG.1 (b), this press member 90 is a part of the said surplus part among the parts which oppose the floor surface of a building in the waterproof sheet 60 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 70). For example, when the width of the shutter 1 is 2900 mm, the width of the lower insertion member 70 having a large width is 600 mm, and the width of the lower insertion member 70 having a short width is 300 mm, the four lower insertion members 70 having a long width are used. And the one lower insertion member 70 with the said short width | variety is arrange | positioned without a mutual gap | interval, respectively, Then, the press member 90 is mounted in the vicinity part of this surplus part. At this time, it is preferable that the pressing member 90 is not disposed at the left end portion or the right end portion of the lower gap 32, so that the excess portion (width = 200 mm) does not occur at the left end portion or the right end portion of the lower gap 32. The insert member 70 is disposed. Since the pressing member 90 can press the portion corresponding to the surplus portion of the waterproof sheet 60 even when the surplus portion is generated in the lower gap 32 in the fully closed state of the opening, the waterproof sheet 60 and the floor surface of the building It is possible to further suppress the intrusion of water from the gaps between the two.

  With the above-described infiltration prevention structure, water can be prevented from entering from the lower gap 32 in the fully closed state of the opening. In particular, the waterproof sheet 60 is not pressed against the floor surface of the building by the weight of the member, but the waterproof sheet 60 is pressed against the floor surface of the building by the insertion of the lower insertion member 70. The same lower insertion member 70 can be used regardless of the strength. Therefore, it is possible to reduce the weight of the member used in the structure, and it is possible to improve the installation property. In addition, as shown in FIGS. 1A and 1B, in addition to a part of the waterproof sheet 60 being sandwiched between the side insertion member 80 and the left (or right) guide rail 14. The lower insertion member 70 and the floor of the building sandwich the portion of the waterproof sheet 60 that faces the floor of the building in the vicinity of the lower end portion of the left (or right) guide rail 14. Since the waterproof sheet 60 can be held more firmly, it is possible to further suppress the intrusion of water from the gap between the guide rail 14 and the waterproof sheet 60.

(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 80 connected to the waterproof sheet 60 and a part of the waterproof sheet 60 are placed on the left side 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. Insert into the side gap 33. At this time, the lower end portion of the side insertion member 80 is brought into contact with the floor surface of the building (the same applies to the side insertion member 80 not connected to the waterproof sheet 60 described later).

  Next, the waterproof sheet 60 is disposed so as to reach at least the outer surface of the shutter curtain 30 to the floor of the building so that the lower gap 32 is covered by the waterproof sheet 60, and the downward difference inserted into the lower gap 32. It arrange | positions so that it may be in the state extended outside the building rather than the insertion member 70. FIG.

  Next, a part of the side insertion member 80 and the waterproof sheet 60 that are not connected to the waterproof sheet 60 is inserted into the right gap 34 from the center in the width direction of the opening 3 toward the right guide rail 14. At this time, the lower end portion of the side insertion member 80 is brought into contact with the floor surface of the building.

  Next, the lower gap 32 is formed by shifting the engagement of the lowermost slat 30a and the fitting portion 30b of the adjacent slat 30a by lifting the seat plate 31 upward. Then, by inserting a part of the plurality of lower insertion members 70 and the waterproof sheet 60 into the lower gap 32 from the outside of the building to the inside thereof, the waterproof sheet 60 is attached to the lower end of the seat plate 31. And the lower insertion end portion 72 of the main body portion 71 of the lower insertion member 70 and the lower insertion end portion 72 and the floor of the building. In this case, the lower insertion member 70 is inserted into the lower gap 32 so that the lower insertion member 70 does not wobble. In addition, among the plurality of lower insertion members 70, the leftmost lower insertion member 70 is brought into contact with the side insertion member 80 connected to the waterproof sheet 60 and the rightmost lower insertion member 70. The member 70 is brought into contact with the side insertion member 80 that is not connected to the waterproof sheet 60.

  Subsequently, the pressing member 90 is placed in the vicinity of the surplus portion of the portion of the waterproof sheet 60 that faces the building floor. This completes the installation of the flood prevention structure.

  In addition, when removing a water immersion prevention structure, the press member 90 is removed from the waterproof sheet 60 first. Next, the side insertion member 80 to which the waterproof sheet 60 is not connected is removed from the right side gap 34. Next, the plurality of lower insertion members 70 are removed from the waterproof sheet 60. In this case, when the lower insertion member 70 is inserted relatively firmly, the plurality of lower insertion members 70 may be removed after the shutter curtain 30 is moved upward. Then, the side insertion member 80 to which the waterproof sheet 60 is connected is removed from the left side gap 33.

Since the lower insertion end 72 and a part of the waterproof sheet 60 are inserted into the lower gap 32 so as to be sandwiched between the lower insertion end 72 and the floor of the building, the waterproof sheet 60 And the lower insertion member 70 can prevent water from entering from the lower gap 32. In particular, the waterproof sheet 60 can be pressed against the floor of the building by the insertion pressure of the member rather than pressing the waterproof sheet 60 against the floor of the building by the weight of the member. There is no need to increase the weight of the (lower insertion member 70), and the same member (lower insertion member 70) can be used. Therefore, compared with the prior art, it is possible to reduce the weight of the member (lower insertion member 70) used for preventing flooding, and to improve the installation property of the flooding prevention structure.

  Further, the lower insertion member 70 causes a part of the waterproof sheet 60 to be in close contact with the floor surface of the building by applying a restoring force generated by its own pressure deformation to a part of the waterproof sheet 60. Therefore, when the lower insertion member 70 is inserted into the lower gap 32 in the fully closed state of the opening, a part of the waterproof sheet 60 can be brought into close contact with the floor of the building by the contact portion 75. It becomes possible to further suppress the intrusion of water from the gap between the floor surface and the waterproof sheet 60.

  In addition, since the close contact portion 75 is formed on the lower surface of the lower insertion member 70 so as to be deformable according to the surface shape of the floor surface of the building, the close contact portion 75 regardless of the surface shape of the floor surface of the building. By this, a part of the waterproof sheet 60 and the floor surface of the building can be brought into close contact with each other in a predetermined area, and water can further be prevented from entering from a gap between the floor surface of the building and the waterproof sheet 60. It becomes possible.

  Moreover, since the 1st notch part 73 was formed in the edge part on the opposite side to the downward insertion end part 72 in the downward insertion member 70, a finger | toe can be hooked on the 1st notch part 73, and a downward insertion member 70 can be easily inserted into a predetermined position. Moreover, compared with the case where the 1st notch part 73 is not provided, the weight reduction of the lower insertion member 70 can be achieved, and the manufacturing cost of the lower insertion member 70 can be reduced.

  Further, in the fully closed state of the opening, the waterproof sheet 60 is extended to the outside of the building from the lower insertion member 70 inserted into the lower gap 32, so that the extension portion of the waterproof sheet 60 is pressed by water. Therefore, it is possible to further suppress the intrusion of water from the gap between the floor surface of the building and the waterproof sheet 60.

  Further, a side insertion member 80 for insertion into the left side gap 33 (or right side gap 34) from the center side in the width direction (left and right direction) of the opening 3 toward the left (or right side) guide rail 14 side. Since the portion from the upper end portion of the waterproof sheet 60 to the lower gap 32 is sandwiched by the side insertion member 80 and the guide rail 14, it is possible to further suppress the waterproof sheet 60 from being turned up by running water, It is possible to further suppress the intrusion of water from the gap between the floor surface of the building and the waterproof sheet 60.
