  Embodiments according to the present invention will be described below in detail with reference to the drawings. In addition, this invention is not limited by this embodiment. In addition, constituent elements in the following embodiments include those that can be easily replaced by those skilled in the art or those that are substantially the same.

[Embodiment 1]
FIG. 1 is a plan view illustrating a schematic configuration of a water stop device for an opening according to the first embodiment. The opening water stop device 1 of the embodiment shown in FIG. 1 and FIG. 2 prevents water from entering the inside of the structure S from the opening O. The opening O is formed in the wall W of the structure S or the like, and is formed to communicate one space side (for example, the outdoor side) of the structure S and the other space side (for example, the indoor side). The In the present embodiment, an example in which the frame body 2 described later is disposed on the wall portion W around the opening portion O is illustrated, but not limited thereto, the opening portion O is a wall that partitions the inside of the structure S It may be formed in the part. The term “prevention” includes meanings such as prevention and suppression.

  In such an opening O of the structure S, a shutter or an opening / closing door is often installed as an opening / closing body. For example, shutters and open / close doors are often installed at the entrances of underground parking lots and stores. Since the shutter has a structure with many gaps, if the amount of precipitation is higher than expected, such as during guerrilla heavy rain or flooding, there is a possibility that the facility will be damaged by flooding through the gaps in the shutter. Moreover, since there is a gap between the doors and between each door and the opening, the opening / closing door may similarly cause damage to the facility.

  The water stop device 1 for the opening of the embodiment shown in FIG. 1 to FIG. 3 allows water to enter the inside of the structure S through the opening O formed in the structure S including a structure such as a building, a house, or a warehouse. It is to prevent that. In the following description, a portion that should prevent water from entering the structure S in the opening O is referred to as a “predetermined portion”. The predetermined portion is the lower end in the vertical direction of the opening O. Let H be the height in the vertical direction from the floor surface F of this predetermined portion. In addition, the floor surface F as used in the field of this invention is the expression for the sake of convenience for explanation, and is not only a normal floor surface F but also a surface located below an opening O such as a concrete surface or the ground. Are collectively referred to.

  In the following description, the X direction shown in FIG. 1 is a “depth direction” from the upstream side (outdoor side) to the downstream side (indoor side). Further, the Y direction shown in FIG. 1 is a direction along the horizontal direction, and a “door width direction (width direction)” in which a pair of vertical frame members (frame members, vertical standing) 21 of the frame 2 described later face each other. It is. The Z direction shown in FIG. 2 is an “up and down direction (vertical direction)” in which the pair of vertical frame members 21 of the frame 2 extends. Here, the indoor side is a side where water intrusion is to be prevented, that is, the side where water intrusion is to be prevented or suppressed, and the outdoor side is a side from which water that may enter may flow. In addition, the outdoor side and the indoor side are words for convenience meaning the upstream side and the downstream side when water may enter. The present invention can also be applied to doors installed in places where concepts such as houses and rooms such as passages such as corridors are not always clear.

  As shown in FIG. 1, the frame 2 is made of a metal material that is thicker than the wall portion W around the opening O and has rust prevention properties. As shown in FIG. 2, the frame 2 is fixedly installed on the structure S so as to surround the periphery of the opening O. The frame 2 includes a pair of left and right vertical frame members 21, an upper frame member (not shown), and a lower frame member (baseboard) 22. The pair of vertical frame members 21, the upper frame member, and the lower frame member 22 are each formed in a hollow cross-sectional shape by a plate-shaped metal material.

  A pair of the vertical frame members 21 are disposed to face both ends of the opening O in the door width direction, and extend in the vertical direction. As shown in FIGS. 1 and 2, the pair of vertical frame members 21 are disposed on the outdoor side with respect to the door 3 described later. The pair of vertical frame members 21 have opposing surfaces 21a that face each other across the space portion of the opening O in the door width direction. The upper frame member is disposed above the opening O. The lower frame member 22 is disposed above the floor surface F on the lower side of the wall W adjacent to the opening O. The upper frame member and the lower frame member 22 extend in the door width direction. The upper end portions of the pair of vertical frame members 21 and both end portions of the upper frame member are connected on the inner surface side of the opening O. Moreover, the lower end part of a pair of vertical frame member 21 and the one end part of the lower frame member 22 are connected. The frame 2 configured in this way has a shape corresponding to the opening O as a whole.

  As shown in FIGS. 1 and 2, the open / close door 3 is provided on the indoor side of the frame body 2 and has a pair of double-open doors 31 that are slidably supported in the door width direction. The opening / closing door 3 opens the opening O by sliding in the door width direction with respect to the frame 2 over the closed position where the door 31 closes the opening O and the opening position where the opening O is opened. Or it closes. Specifically, in the open / close door 3, the pair of doors 31 approach each other to close the opening O, and the pair of doors 31 separate from each other to open the opening O. Such movement of the door 31 may be performed manually or automatically by a driving device such as a motor. Further, since the opening / closing door 3 does not come into contact with the reinforcing plate 4 described later, the opening / closing door 3 can be opened / closed with the reinforcing plate 4 installed in the opening O.

  The door 31 is guided by a guide rail (not shown). The guide rails are disposed at both upper and lower ends of the opening O, and are parallel to the surface of the wall W. Both ends in the vertical direction of the door 31 are inserted into the groove portions of the guide rail, respectively. The groove portion extends in the opening / closing direction, that is, the door width direction, and guides the door 31 to be slidable in the door width direction. As shown in FIG. 1, door-side vertical stands 31 a thicker than the door 31 are disposed at both ends of the door 31 in the door width direction. As shown in FIG. 2, a door-side skirting board 31 b that is thicker than the door 31 is disposed at the lower end of the door 31. The thickness of the door-side vertical stand 31a is equal to the thickness of the door-side skirting board 31b.

  The reinforcing plate 4 is disposed on the floor F on the outdoor side in contact with the outdoor side surface 21 b of the pair of vertical frame members 21. The reinforcing plate 4 is formed in a panel shape by processing a plate-like metal material having rust prevention properties. As shown in FIGS. 1 to 3, the reinforcing plate 4 has a width and a height capable of closing a predetermined portion of the opening O. This reinforcing plate 4 allows the structure S to enter and exit through the open / close door 3 when a person straddles it. Specifically, the reinforcing plate 4 is formed so that the width L1 is larger than the width L of the opening O, and the height H1 in the vertical direction at the time of installation is larger than the height H of the predetermined portion. Further, the height H1 of the reinforcing plate 4 may be lower than the upper end of the sheet 6 installed in the opening O (or lower than the height H of the predetermined portion) depending on the required performance. The water stop device 1 of the part can cope with a water level up to the height H1. It is desirable that the height H1 of the reinforcing plate 4 is such that a person can straddle it. For example, 16 (upper limit of the height of the staircase for elementary school children stipulated in the Building Standards Law Enforcement Ordinance) cm to 38 (JIS) (Japanese Industrial Standard) The height of the seat surface of classroom chair No. 4 for a person with a height of 150 cm in S1021 is preferably about cm. Further, the height H1 of the reinforcing plate 4 may be up to about 1 m on the assumption that the chair is laid over a chair depending on the required performance of the water stop height, and 1.5 m on the assumption that it is crossed using a stepladder or the like. It may be up to about.

  The reinforcing plate 4 is configured by connecting a plurality of plate-like members in the door width direction. In the present embodiment, the reinforcing plate 4 includes a first reinforcing plate 41 and a second reinforcing plate 42 into which the first reinforcing plate 41 can be inserted and retracted. In addition, the reinforcing plate 4 has a fixing means (not shown) including a stopper that inserts the first reinforcing plate 41 into the second reinforcing plate 42 and fixes the reinforcing plate 4 to a desired width. The fixing means may fix the width of the reinforcing plate 4 at intervals of several millimeters or may be fixed in a stepless manner.

  The first reinforcing plate 41 is a rectangular frame in which a magnet including stainless steel is adsorbed and a lightweight metal plate having a rust prevention property is processed into a U-shaped cross section to form an aggregate, and four aggregates are combined. Have The first reinforcing plate 41 is formed by closing the front and back openings of the frame with square panels formed of a lightweight metal plate having rust prevention properties including aluminum. The surfaces closed by the rectangular panel become the indoor side surface 41a and the outdoor side surface 41b of the first reinforcing plate 41. The first reinforcing plate 41 is filled with a filler in an internal space surrounded by a frame and a panel. The width of the first reinforcing plate 41 is smaller than the width L1. In addition, the first reinforcing plate 41 is provided with a vertical water-stopping rubber (first water-stopping rubber) 5 described later at one end portion of the indoor side surface 41a in the door width direction. The first reinforcing plate 41 can be accommodated in the second reinforcing plate 42 so that the other end portion in the door width direction can freely advance and retract in the door width direction. Further, the first reinforcing plate 41 can be separated from the second reinforcing plate 42 by being advanced from the second reinforcing plate 42 and pulled out.

  The second reinforcing plate 42 is a rectangular frame in which a magnet including stainless steel is adsorbed and a lightweight metal plate having a rust prevention property is processed into a U-shaped cross section to form an aggregate, and four aggregates are combined. Have The second reinforcing plate 42 is formed by closing the front and back openings of the frame with square panels formed of a lightweight metal plate having rust prevention properties including aluminum. The surfaces closed by the rectangular panel become the indoor side surface 42a and the outdoor side surface 42b of the second reinforcing plate 42. The second reinforcing plate 42 can be inserted into the internal space surrounded by the frame and the panel so that the first reinforcing plate 41 can move forward and backward in the door width direction. The width of the second reinforcing plate 42 is smaller than the width L1. Further, the width of the second reinforcing plate 42 is equal to the width of the first reinforcing plate 41. The height of the second reinforcing plate 42 is larger than the height of the first reinforcing plate 41. The thickness of the second reinforcing plate 42 in the depth direction is larger than the thickness of the first reinforcing plate 41 in the depth direction. Further, the second reinforcing plate 42 is provided with a vertical water stop rubber 5 described later at the other end portion of the indoor side surface 42a in the door width direction.

  The leg portion 43 and the pedestal 44 form a pair with a leg portion 45 and a pedestal 46, which will be described later, and allow the reinforcing plate 4 to stand vertically on the floor surface F. The leg part 43 is formed in a substantially rectangular shape with a flat plate material. The leg portion 43 extends from the one end face 41 c in the door width direction of the first reinforcing plate 41 to the outdoor side in the depth direction. The pedestal 44 extends downward from the outdoor side in the depth direction of the leg portion 43.

  The leg portion 45 and the pedestal 46 form a pair with the leg portion 43 and the pedestal 44 so that the reinforcing plate 4 stands upright on the floor surface F. The leg part 45 is a flat plate material and is formed in a substantially rectangular shape. The leg portion 46 extends from the other end surface 42c in the door width direction of the second reinforcing plate 42 to the outdoor side in the depth direction. The pedestal 46 extends downward from the outdoor side in the depth direction of the leg portion 45.

  The reinforcing plate 4 having such a configuration allows the width L1 to be adjusted by moving the first reinforcing plate 41 forward and backward with respect to the second reinforcing plate 42. In the present embodiment, the reinforcing plate 4 is installed in the opening O in a state where the first reinforcing plate 41 is inserted about half of the second reinforcing plate 42 in the door width direction. Moreover, the double part in which the 1st reinforcement board 41 and the 2nd reinforcement board 42 overlapped is called the overlapping part 4a. The overlapping portion 4a may set a ratio to the width L1 according to the required performance of the reinforcing plate 4. In the present embodiment, the overlapping portion 4a has a width of about one third with respect to the width L1. The reinforcing plate 4 has a high rigidity due to the overlapping portion 4a. For this reason, the reinforcing plate 4 is allowed to bend indoors due to water pressure acting on the reinforcing plate 4 from the outdoor side when the outdoor side is submerged.

  The vertical water stop rubber 5 is disposed at one end portion of the indoor side surface 41 a of the first reinforcing plate 41 in the door width direction and the other end portion of the indoor side surface 42 a of the second reinforcing plate 42 in the door width direction. The vertical water stop rubber 5 is disposed over the entire length of the first reinforcing plate 41 and the second reinforcing plate 42 in the short direction (height direction). In the present embodiment, the vertical water stop rubber 5 extends to the bottom surfaces of the first reinforcing plate 41 and the second reinforcing plate 42 in order to effectively prevent water from entering. If there is no problem in use, the vertical water stop rubber 5 may not extend to the bottom surfaces of the first reinforcing plate 41 and the second reinforcing plate 42. The longitudinal water blocking rubber 5 disposed on the first reinforcing plate 41 and the second reinforcing plate 42 forms a pair. As shown in FIG. 4, the vertical water blocking rubber 5 is interposed between the reinforcing plate 4 and the vertical frame member 21 in a state where the reinforcing plate 4 is installed in the opening O. Further, the vertical water blocking rubber 5 is interposed between the bottom surface of the first reinforcing plate 41 and the second reinforcing plate 42 and the floor surface F in a state where the reinforcing plate 4 is installed in the opening O. When the outdoor side is submerged and a water pressure acts on the reinforcing plate 4 from the outdoor side to the indoor side, the vertical water stop rubber 5 is pressed by the vertical frame member 21 and elastically deformed. For this reason, the pair of vertical water blocking rubbers 5 are in close contact with the pair of vertical frame members 21. For this reason, the pair of vertical waterproofing rubbers 5 block the space between the reinforcing plate 4 and the contact portions of the pair of vertical frame members 21 and suppress the flow of water. That is, the pair of vertical water blocking rubbers 5 prevents water from entering the indoor side from the outdoor side in the pair of vertical frame members 21.

  The sheet 6 closes at least the space between the reinforcing plate 4 and the floor surface F and stops water. The seat 6 covers the vertical lower ends of the outdoor side surface 41b of the first reinforcing plate 41 and the outdoor side surface 42b of the second reinforcing plate 42. In the present embodiment, the sheet 6 covers the entire surface exposed to the outdoor side on the outdoor side surface 41 b of the first reinforcing plate 41 and the outdoor side surface 42 b of the second reinforcing plate 42. The sheet 6 closes the gap between the first reinforcing plate 41 and the second reinforcing plate 42 in the overlapping portion 4a of the reinforcing plate 4 and stops water appropriately. Further, the seat 6 is held so that the lower end portion in the vertical direction extends toward the outdoor side along the floor surface F.

  In the present specification, the reinforcing plate is in a state in which the sheet 6 is held by a holding member constituted by a pressing member 7, a first magnet 8, and a second magnet 9, which will be described later, on the upper side in the vertical direction of the sheet 6. The portion extending along the line 4 is hereinafter referred to as “sheet upper portion 6b”. Further, in this specification, a portion that extends along the floor surface F in a state where the sheet 6 is held by the holding member on the lower side (vertical lower end portion) of the sheet 6 is hereinafter referred to as “sheet”. The lower part 6c "is described.

  The sheet 6 has water shielding properties and can function as a waterproof sheet for the opening O. Further, the sheet 6 has flexibility and may be stretchable. The material of the sheet 6 can be, for example, resin, rubber, or a cloth whose surface is coated with resin. The sheet 6 is preferably made of a material that can be deformed by following water pressure. The shape of the sheet 6 is, for example, a rectangle.

  The width of the sheet 6 is greater than the width of the reinforcing plate 4 installed in the opening O. In the present embodiment, the width of the sheet 6 is larger than the width of the reinforcing plate 4 installed in the opening O. For this reason, the sheet | seat 6 is installed in the reinforcement board 4 in the state folded in the folding part 6a according to the width | variety of the reinforcement board 4. FIG. In addition, when the width | variety of the sheet | seat 6 is the same width as the reinforcement board 4 installed in the opening part O, the sheet | seat 6 is not folded, but is installed in the reinforcement board 4 in the state where wrinkles and slack were stretched | stretched and stretched moderately. The

  The height of the seat 6 is determined based on the water depth to be supported, that is, the height H of the predetermined portion. That is, the height of the seat 6 is determined based on which range is covered and waterproofed by the seat 6 from the lower end of the reinforcing plate 4 toward the upper side in the vertical direction. More specifically, the height of the sheet 6 is larger than the height H of the predetermined portion of the opening O, and is set to a length as shown below. That is, in a state where the sheet 6 is held by the first magnet 8, it is possible to hang the sheet lower portion 6 c on the floor surface F and to follow the floor surface F. The seat 6 is installed with the seat lower portion 6c extending along the floor surface F toward the outdoor side. In other words, the seat 6 is disposed so as to face the floor surface F provided in the seat lower portion 6c and to be separated from the reinforcing plate 4 as the seat lower portion 6c moves toward the front end side.

  The pressing member 7 presses the sheet 6 toward the floor surface F and the outdoor side surface 41 b of the first reinforcing plate 41 and the outdoor side surface 42 b of the second reinforcing plate 42. As shown in FIGS. 1 and 2, the pressing member 7 is continuously arranged along the door width direction of the opening O on the seat lower portion 6c. The pressing member 7 may be disposed without a gap or may be disposed with a predetermined gap between the adjacent pressing members 7. The pressing member 7 is preferably rod-shaped or plate-shaped. The pressing member 7 according to the present embodiment is a plate-like flat bar. The pressing member 7 is made of metal, for example, and has a mass and a density capable of pressing the sheet lower portion 6c toward the floor surface F against buoyancy. The pressing member 7 is installed on the seat lower portion 6 c after the seat lower portion 6 c is arranged along the floor surface F. It is preferable that the pressing member 7 is a position corresponding to the folding portion 6a of the sheet lower portion 6c on the floor surface F and / or a position where the sheet 6 is folded. More specifically, if the pressing member 7 is continuously disposed along the door width direction of the opening O, the pressing member 7 is placed at a position where the sheet 6 is folded. Even if it is a case where it is arranged discontinuously along the door width direction, it is preferable that the seat 6 is placed in a folded position. Thereby, the pressing member 7 can keep the sheet 6 in close contact with the floor surface F in the vicinity of the lower end portion of the reinforcing plate 4. The pressing member 7 may be one, or may be continuously arranged along the door width direction of the opening O as a result even if it is divided into a plurality. In addition, as long as the water stop purpose in use can be achieved, there may be a portion that is not continuous and is somewhat interrupted.

  The first magnet 8 positions the sheet 6 on the outdoor side of the reinforcing plate 4 and holds it with respect to the reinforcing plate 4. The first magnet 8 is attracted to the reinforcing plate 4. Further, the first magnet 8 holds both ends of the seat 6 in the door width direction so that the seat lower portion 6c extends toward the outdoor side along the floor surface F. Thereby, the sheet | seat 6 can block | close the clearance gap which the reinforcement board 4 has in the overlapping part 4a, and the clearance gap between the reinforcement board 4 and the floor surface F, and can suppress the water immersion to the indoor side. As shown in FIG. 2, a pair of first magnets 8 are provided and are detachable from the reinforcing plate 4. The first magnet 8 allows the sheet 6 to bend toward the reinforcing plate 4 rather than the first magnet 8 due to water pressure acting on the reinforcing plate 4. Further, in order to hold the sheet 6 against the reinforcing plate 4 effectively, the first magnet 8 is disposed so that the lower end portion thereof is as close as possible to the floor surface F so that the sheet 6 is in close contact with the floor surface F. It is preferable that If there is no problem in use, the lower end of the first magnet 8 may be disposed away from the floor surface F. The 1st magnet 8 should just be what has such a function, for example, it is preferred to make it a shape with easy handling, such as rod shape, plate shape, and sheet shape. The first magnet 8 is preferably made of a deformable material including an elastic material, for example. The first magnet 8 according to this embodiment is a sheet having elasticity.

  When attached to the reinforcing plate 4, the first magnet 8 extends in the vertical direction and is disposed in a range corresponding to a predetermined portion of the opening O. That is, the first magnet 8 is arranged corresponding to the range from the lower end of the reinforcing plate 4 to the upper end of the predetermined portion. In the present invention, the first magnet 8 only needs to correspond to the predetermined portion of the opening O in a substantial sense that there is no problem in use such as the waterproof performance of the water stop device 1 of the opening. For example, the upper end of the first magnet 8 does not necessarily coincide with the upper end of the predetermined portion, and may be positioned slightly below. The first magnet 8 may be formed integrally with the sheet 6.

  The second magnet 9 positions the sheet 6 on the outdoor side of the reinforcing plate 4 and holds it with respect to the reinforcing plate 4. The second magnet 9 is attracted to the reinforcing plate 4. The second magnet 9 is attached to the upper end portion of the seat 6 with an interval in the door width direction of the seat 6. In the present invention, all or a part of the second magnet 9 may be replaced with another holding member such as a suction cup, a pinch (clip), an adhesive material, a hook, a fastener, a string, and a hook, and the sheet 6 is replaced with a holding member. The fixing to the reinforcing plate 4 (for example, the second magnet 9 or the like) may be performed according to the necessity of suppressing the deflection of the sheet 6.

  The usage method of the water stop apparatus 1 of the opening part comprised as mentioned above is demonstrated. When installing the water stop device 1 of the opening in the opening O, the operator carries the reinforcing plate 4, the sheet 6, and the holding member from the storage location.

  The operator places the reinforcing plate 4 from the outdoor side at the installation position of the reinforcing plate 4 in the opening O. Specifically, the operator inserts the first reinforcing plate 41 into the second reinforcing plate 42 and connects the first reinforcing plate 41 and the second reinforcing plate 42. Then, the worker advances and retracts the first reinforcing plate 41 with respect to the second reinforcing plate 42 so that the pair of vertical waterproofing rubbers 5 are in contact with the pair of vertical frame members 21, thereby reinforcing the reinforcing plate 4. Adjust the width. Then, the worker makes the bottom surface of the reinforcing plate 4 stand vertically to the floor surface F at the installation position of the reinforcing plate 4. Further, the pair of vertical water blocking rubbers 5 are in contact with the pair of vertical frame members 21.

  Then, the operator aligns one end portion of the seat 6 with one end portion of the outdoor side surface 41b of the first reinforcing plate 41 in the door width direction, extends the seat upper portion 6b along the reinforcing plate 4, and extends the seat lower portion 6c. It extends toward the outdoor side along the floor surface F. The operator causes the reinforcing plate 4 to hold one end portion of the sheet 6 with the first magnet 8.

  Then, the worker spreads the seat 6 along the door width direction in a state where one end of the seat 6 is held by the first magnet 8. The operator, while spreading the sheet 6, sequentially adsorbs the second magnet 9 to the reinforcing plate 4 from the one near the one end held and temporarily fixes the sheet 6 to the reinforcing plate 4.

  Then, the operator aligns the other end portion of the seat 6 with the other end portion of the outdoor side surface 42 b of the second reinforcing plate 42 in the door width direction, and holds the reinforcing plate 4 by the first magnet 8.

  Since the width of the sheet 6 is larger than the width L of the opening O (see FIG. 2), the sheet 6 has a slack in the central portion in the door width direction in a state where both ends of the sheet 6 are held by the first magnet 8. doing. Then, the operator folds the sheet 6 at the folding portion 6a according to the dimensional difference between the width of the sheet 6 and the width L of the opening O. At this time, the operator pulls the seat 6 in the door width direction toward the center portion in the door width direction so as to extend the wrinkles and slacks of the portion directly covering the reinforcing plate 4. The folding part 6 a is positioned on the overlapping part 4 a of the reinforcing plate 4. In addition, it is preferable that the front-end | tip (mountain fold part) of the folding part 6a is hold | maintained by the 2nd magnet 9. FIG. When the surplus portion is folded in half, it is preferable to fold the sheet lower portion 6c together with the sheet upper portion 6b in order to suppress the occurrence of a gap between the floor surface F and the sheet 6. In the present embodiment, the seat lower portion 6c is folded together with the seat upper portion 6b.

  In this manner, the sheet 6 is in a properly stretched state with the wrinkles and the slack portion being stretched. Thereby, it is suppressed that a clearance gap arises between the reinforcement board 4 and the sheet | seat 6, and a clearance gap produces between the floor surface F and the sheet | seat 6. FIG. At this time, the sheet 6 integrally covers the reinforcing plate 4 and the floor surface F. Thereby, the sheet | seat 6 obstruct | occludes the clearance gap between the floor surface F and the reinforcement board 4, and stops water. In addition, the sheet 6 stops water in the gap between the first reinforcing plate 41 and the second reinforcing plate 42 in the overlapping portion 4 a of the reinforcing plate 4.

  Then, the operator places the pressing member 7 on the sheet lower portion 6c of the sheet 6 covering the floor surface F. More specifically, the operator places the pressing member 7 on the floor surface F at a position corresponding to the folding portion 6a of the seat lower portion 6c and / or a position where the seat 6 is folded. Thereby, it is suppressed that water permeates between the sheet 6 and the floor surface F. Further, even if water enters between the seat lower portion 6 c and the floor surface F, the seat lower portion 6 c is suppressed from floating from the floor surface F. Further, the position of the seat lower portion 6c is prevented from being displaced due to the momentum of the water flow. Thus, the water stop effect by the sheet 6 can be enhanced by the pressing member 7. Further, by placing the pressing member 7 on the folding portion 6a on the floor surface F, the lifting of the folding portion 6a is suppressed, and the water stop effect of the sheet 6 is enhanced.

  In this way, the water stop device 1 at the opening portion has the pressing member in a state in which the sheet 6 integrally covers the reinforcing plate 4 and the floor surface F and the sheet lower portion 6c extends along the floor surface F toward the outdoor side. 7, the sheet 6 is pressed toward the floor surface F and the reinforcing plate 4. Thus, the water stop device 1 for the opening is installed in the opening O.

  When water pressure acts on the reinforcing plate 4 during the water immersion on the outdoor side, the reinforcing plate 4 is pressed to the vertical frame member 21 side, and the vertical water-stopping rubber 5 is elastically deformed and closely contacts the vertical frame member 21. Further, due to the water pressure acting on the seat 6, the seat upper portion 6 b is pressed against the reinforcing plate 4 and is in close contact with it, and the seat lower portion 6 c is pressed against and in close contact with the floor surface F. In this way, the water stop device 1 at the opening can provide high water stop.

  Next, when removing the water stop device 1 of the opening installed in the opening O, the operator removes the pressing member 7, the first magnet 8, and the second magnet 9. Then, the operator removes the sheet 6 from the reinforcing plate 4. Then, the operator removes the reinforcing plate 4 from the opening O. Then, the operator advances the first reinforcing plate 41 from the second reinforcing plate 42 and pulls it out to separate it from the first reinforcing plate 41 and the second reinforcing plate 42. And an operator conveys the 1st reinforcement board 41 and the 2nd reinforcement board 42 to a storage place separately. Further, the operator carries the sheet 6 and the holding member to the storage location. Then, the operator retracts and stores the first reinforcing plate 41 in the second reinforcing plate 42 to shorten the reinforcing plate 4 and then stores it in the storage place. In this way, the reinforcing plate 4 installed in the opening O is removed.

  According to the water stop device 1 of the opening according to the embodiment described above, the reinforcing plate 4 connects the first reinforcing plate 41 and the second reinforcing plate 42 to make the first reinforcing plate 41 the second reinforcing member. The width can be adjusted in accordance with the width L of the opening O by advancing and retracting the plate 42. Further, a folded portion 6 a of the sheet 6 is disposed on the overlapping portion 4 a of the reinforcing plate 4. For this reason, the water stop device 1 at the opening can stop the gap between the first reinforcing plate 41 and the second reinforcing plate 42 in the overlapping portion 4 a by the sheet 6. Thus, since it is not necessary to arrange water-stopping members such as packing in the overlapping portion 4a, the reinforcing plate 4 can have a simple configuration. Accordingly, the reinforcing plate 4 does not require maintenance such as periodically checking and replacing the water stop member.

  Moreover, in the water stop apparatus 1 of an opening part, the width | variety of the reinforcement board 4 can be shortened and size-reduced by retracting the 1st reinforcement board 41 with respect to the 2nd reinforcement board 42. FIG. Since this 2nd reinforcement board 42 accommodates the 1st reinforcement board 41, since the internal space is not filled with the filler, it can be reduced in weight. Further, the first reinforcing plate 41 can be separated from the second reinforcing plate 42 by being advanced from the second reinforcing plate 42 and pulled out. For this reason, the divided first reinforcing plate 41 and second reinforcing plate 42 can be reduced in size and weight, respectively. Thus, since the reinforcing plate 4 is reduced in size and weight, the water-stop device 1 at the opening can be easily handled during transportation and storage.

  In the water stop device 1 at the opening, the width L1 of the reinforcing plate 4 can be adjusted by moving the first reinforcing plate 41 forward and backward with respect to the second reinforcing plate 42. For this reason, the reinforcing plate 4 can be installed in various openings O.

  Moreover, in the water stop apparatus 1 of an opening part, the reinforcement board 4 can acquire high rigidity by having the overlapping part 4a. For this reason, the water stop apparatus 1 of an opening part can suppress that the reinforcement board 4 bends indoors with the water pressure which acts on the reinforcement board 4 from the outdoor side at the time of the water immersion of the outdoor side.

  Further, in the water stop device 1 of the opening, when the reinforcing plate 4 is installed in the opening O, the vertical water stop rubber 5 is interposed between the reinforcing plate 4 and the pair of vertical frame members 21, and the sheet 6 The seat lower part 6c extends between the floor surface F. And a pair of vertical water stop rubber | gum 5 is pressed by a pair of vertical frame member 21, is elastically deformed, and closely_contact | adheres, and the sheet | seat lower part 6c is pressed by the floor surface F, and contact | adheres. In this way, the water stop device 1 at the opening can suppress the flow of water between the contact portions of the reinforcing plate 4 and the pair of vertical frame members 21 by the vertical water stop rubber 5. Moreover, the water stop apparatus 1 of an opening part can suppress that water flows between the reinforcement board 4 and the floor surface F by the sheet | seat lower part 6c. Thus, the water stop device 1 at the opening can prevent water from entering the indoor side from the outdoor side.

  More specifically, when the water volume on the outdoor side increases due to flooding or guerrilla heavy rain, the seat lower portion 6c first comes into contact with water. The seat lower portion 6c is pressed toward the floor surface F by water pressure, and the seat lower portion 6c comes into close contact with the floor surface F. Thereby, the sheet | seat lower part 6c can suppress that water permeates from between the floor surfaces F. Further, since the sheet lower portion 6c is pressed toward the floor surface F by the pressing member 7, the sheet lower portion 6c more reliably infiltrates through the gap with the floor surface F even in the case of a low water level. Can be suppressed. Further, the pressing member 7 can suppress the sheet lower portion 6c from being lifted by a water flow or the like. Thus, the sheet 6 can integrally cover the predetermined portion and the floor surface F adjacent to the predetermined portion by water pressure.

  Further, the sheet 6 is pressed against the reinforcing plate 4 by water pressure. For this reason, as the water level increases, the sheet 6 increases in adhesion to the reinforcing plate 4 and also increases in blockage for closing the gap. Accordingly, the sheet 6 suppresses water from entering the gap between the sheet 6 and the reinforcing plate 4 and between the first reinforcing plate 41 and the second reinforcing plate 42 in the overlapping portion 4a of the reinforcing plate 4. can do. Thus, the sheet 6 has increased water shielding according to the water level, and can appropriately prevent water from entering the indoor side.

  In addition, in the water stop device 1 having such an opening, maintenance such as periodic inspection and replacement of the vertical water stop rubber 5 and the sheet 6 is performed periodically in order to ensure water stop. What is necessary is that the labor, time and cost required for maintenance can be reduced.

  Further, in the water stop device 1 of the opening, when the reinforcing plate 4 is installed in the opening O, the reinforcing plate 4 is placed on the floor surface F in a state where the reinforcing plate 4 is in contact with the vertical frame member 21. The reinforcing plate 4 is easily installed in the opening O. Thus, the water stop device 1 at the opening does not require a tool for installing and removing the reinforcing plate 4, and anyone can easily install and remove it in a short time. Further, when the reinforcing plate 4 is installed in the opening O, there is no need for a holding means, so that a simple structure can be achieved.

  Moreover, in the water stop apparatus 1 of an opening part, since the sheet | seat 6 can be hold | maintained at the reinforcement board 4 with a holding member, a tool is not required and anyone can install and remove easily in a short time. Further, the sheet 6 can have a simple structure.

  Further, in the water stop device 1 at the opening, the reinforcing plate 4 is leaned against the pair of vertical frame members 21 and is not in contact with the open / close door 3, so that it acts on the seat 6 regardless of the open / close state of the open / close door 3. The reinforcing plate 4 can support the water pressure to be performed. That is, the water stop device 1 at the opening can enter and leave the structure S through the center of the opening O. For this reason, even if it is the state installed in the opening part O, the water stop apparatus 1 of an opening part can go in and out of the structure S by opening and closing the opening part O, as shown in FIG.

  Further, since the water stop device 1 at the opening is leaned so that the reinforcing plate 4 is supported by the entire surface of the vertical frame member 21 fixedly disposed on the structure S, the water pressure is dispersed and supported. can do. For this reason, since the water stop apparatus 1 of an opening part has the intensity | strength which can be equal to a water pressure with a simple structure, it can suppress that the reinforcement board 4 falls down after installation, and can suppress the water immersion from the opening part O. Since the height H1 of the reinforcing plate 4 is 16 cm to 38 cm, the water stop device 1 at the opening can reliably enter and exit from the opening O after being installed in the opening O.

  And the water stop apparatus 1 of an opening part does not require repair work to the existing structure S. FIG. Therefore, the water stop device 1 at the opening can be applied to various structures S including the existing structure S.

[Embodiment 2]

The first reinforcing plate 111 and the second reinforcing plate 112 are configured in the same manner as the first reinforcing plate 41 and the second reinforcing plate 42 of the first embodiment. Further, inside the second reinforcing plate 112, the first reinforcing plate 111 is inserted into the second reinforcing plate 112 and the direction in which the first reinforcing plate 111 is always retracted, that is, the width of the reinforcing plate 110 is increased. It has a biasing means (not shown) for biasing in the direction. The urging force of the urging means can resist the water pressure acting on the reinforcing plate 110 when the reinforcing plate 110 is installed in the opening O.

  The seat 120 extends to the outdoor side surface 21b side of the pair of vertical frame members 21 in the door width direction. That is, the sheet 120 integrally covers the predetermined portion of the opening / closing portion O and the pair of vertical frame members 21 that are portions of the structure S adjacent to the predetermined portion. That is, the sheet 120 is larger than the width L of the opening O and extends to the pair of vertical frame members 21 while being held by the reinforcing plate 110 and the pair of vertical frame members 21. In the present embodiment, the sheet 120 covers the entire surface exposed to the outdoor side on the outdoor side surface 111 b of the first reinforcing plate 111 and the outdoor side surface 112 b of the second reinforcing plate 112. The seat lower portion 120c integrally covers a vertical lower end portion of the outdoor side surface 111b of the reinforcing plate 110 and a portion of the pair of vertical frame members 21 adjacent to the vertical lower end portion of the outdoor side surface 111b of the reinforcing plate 110. The sheet 120 closes the gap between the floor surface F and the reinforcing plate 110 to stop water, and closes the space between the reinforcing plate 110 and the pair of vertical frame members 21 to stop water. It is held by a pair of vertical frame members 21. Such a sheet 120 is made of the same material as the sheet 6 of the first embodiment and is formed in the same shape.

  The pressing member 7 is configured similarly to the pressing member 7 of the first embodiment. In the present embodiment, the pressing member 7 faces the sheet 120 toward the floor F, the outdoor side surface 111b of the first reinforcing plate 111, the outdoor side surface 112b of the second reinforcing plate 112, and the pair of vertical frame members 21. To press.

  The first magnet 8 is configured similarly to the first magnet 8 of the first embodiment. In the present embodiment, the first magnet 8 is detachably attached to the pair of vertical frame members 21. The first magnet 8 integrally covers the predetermined portion of the opening O and the pair of vertical frame members 21 that are portions adjacent to the predetermined portion of the structure S so as to close the predetermined portion of the opening O. The sheet 120 is held.

  According to the water stop device 100 for an opening according to the embodiment described above, the reinforcing plate 110 can have a simple configuration as in the first embodiment.

  Moreover, in the water stop apparatus 100 of an opening part, since the reinforcement board 110 is reduced in size and weight similarly to Embodiment 1, the handling at the time of conveyance and accommodation can be made easy.

  Moreover, in the water stop apparatus 100 of an opening part, the sheet | seat 120 has covered the floor surface F, the reinforcement board 110, and a pair of vertical frame member 21 integrally. Therefore, the sheet 120 can block the gap between the floor surface F and the reinforcing plate 110 and the gap between the pair of vertical frame members 21 and the reinforcing plate 110 to stop water. By these, the sheet | seat 120 can block | close the clearance gap which the reinforcement board 110 has in the overlapping part 110a, and the clearance gap between the reinforcement board 110 and a pair of vertical frame member 21, and can suppress the water immersion to the indoor side. That is, since the water stop device 100 at the opening does not have a water stop rubber, maintenance such as periodically inspecting and replacing only the sheet 120 is performed in order to ensure water stop. What is necessary is that the labor, time and cost required for maintenance can be greatly reduced.

  In the above embodiment, the water stop device 1 and 100 of the opening is described as being installed in the opening O where the opening and closing door 3 is disposed, but the opening and closing door 3 does not contact the reinforcing plates 4 and 110. Even if it is the opening part O in which the opening / closing door 3 is not arrange | positioned, the water stop apparatus 1 and 100 of an opening part can be applied.

  Moreover, in the said embodiment, when opening / closing of the door 3 at the time of installation of the reinforcement boards 4 and 110 is not requested | required, you may arrange | position so that the reinforcement boards 4 and 110 may contact the door 3. For example, the central part of the reinforcing plate 4, 110 in the door width direction is installed in a state where it is in contact with the open / close door 3. Accordingly, the water pressure acting on the reinforcing plates 4 and 110 when the outdoor side is submerged is also supported by the door 3. For this reason, the strength required for the reinforcing plates 4 and 110 can be reduced.

  Moreover, in the said embodiment, although demonstrated as what can insert the 1st reinforcement board 41,111 in the 2nd reinforcement board 42,112 so that advancement / retraction was possible, the 1st reinforcement board 41,111 and the 2nd reinforcement board 42 were demonstrated. , 112 may be assembled by connecting via a connecting member including a fastening member such as a screw.

  Further, when the height H of the predetermined portion of the opening O is zero, the sheets 6 and 120 described in the above embodiment are blocked by blocking only between the reinforcing plates 4 and 110 and the floor surface F. That's fine. That is, it is only necessary to hold the reinforcing plates 4, 110 so as to extend from the lower end of the outdoor side surface along the floor surface F toward the outdoor side.

  Moreover, in the said Embodiment 1, although the vertical water stop rubber | gum 5 demonstrated as what was arrange | positioned over the transversal direction (height direction) full length, it is not limited to this. For example, what is necessary is just to become higher than the height H of the predetermined part of the place where the water stop apparatus 1 of an opening part is applied. That is, the vertical water stop rubber 5 only needs to be disposed from the bottom surface of the reinforcing plate 4 to a height H + α of a predetermined portion.
