In addition, this invention is not limited by this embodiment. In addition, constituent elements in the following embodiments include those that can be easily assumed by those skilled in the art or those that are substantially the same.

[First Embodiment]
The first embodiment will be described with reference to FIGS. 1 to 4. The present embodiment relates to a waterproof device for an opening and a waterproof sheet for an opening. FIG. 1 is a perspective view showing a waterproof device for an opening according to a first embodiment of the present invention, FIG. 2 is a horizontal sectional view of the waterproof device for an opening according to the first embodiment, and FIG. FIG. 4 is a vertical sectional view of the waterproof device for an opening according to the embodiment, and FIG.

  A shutter is often attached to an external opening of a structure such as a building. For example, shutters are often provided at the entrances of underground parking lots that are likely to be flooded during floods, and at the entrances of stores that are prone to product damage if flooded. Since the shutter has a structure with many gaps, there is a possibility that these facilities will be damaged by inundation through the gaps of the shutter during heavy rain and flooding.

  As a countermeasure against flooding, a method of changing the lower part of the shutter to a waterproof board (panel) is conceivable. However, since it is generally expensive, it may be difficult for the user to accept.

  The waterproof device 1-1 for the opening according to the present embodiment allows a water to be easily and inexpensively stopped by installing a sheet in front of the shutter. The sheet integrally covers the shutter and the surrounding structure, thereby closing the gap between the shutter and the structure and appropriately stopping water. Therefore, according to the waterproof device 1-1 of the opening part of this embodiment, damage inside the building due to water damage can be reduced.

  The opening waterproofing device 1-1 shown in FIG. 1 closes the opening 2 of the structure 1 and suppresses intrusion of water from the outdoor side to the indoor side. The structure 1 is a building structure such as a factory, a warehouse, a garage, a store, or a house, and has an opening 2. The opening 2 is formed in a wall portion or the like of the structure 1 and communicates the outdoor side and the indoor side of the structure 1.

  Here, the outdoor side indicates a side that is relatively close to the external space of the structure 1, and the indoor side indicates a side that is relatively far from the external space of the structure 1. In other words, the outdoor side is the upstream side when water enters the structure 1 from the external space, that is, the side where water reaches first. The opening 2 can communicate the external space (outdoor) and the internal space (indoor) of the structure 1, for example. The opening 2 of the present embodiment is formed in the wall 3 that forms the outer shell of the structure 1, and communicates between the outdoors and the interior of the structure 1 through the wall 3. However, the present invention is not limited thereto, and the opening 2 may be formed in a wall that partitions the inside of the structure 1.

  The shutter curtain 4 is an opening / closing body that opens and closes the opening 2. The shutter curtain 4 moves in the opening / closing direction, in the present embodiment, in the vertical up / down direction. The shutter curtain 4 is a slat connecting body formed by connecting a plurality of slats 4a in the opening / closing direction. In the present embodiment, the opening direction is the upward direction, and the closing direction is the downward direction.

  As shown in FIG. 2, the shutter curtain 4 is guided by a guide rail 5. The wall 3 has wall surfaces 3 a and 3 b that form the opening 2. The wall surface 3 a and the wall surface 3 b are opposed to each other in the width direction of the opening 2. The guide rails 5 are respectively disposed on the wall surfaces 3a and 3b and face each other in the width direction. Both end portions in the width direction of the shutter curtain 4 are inserted into the groove portions 5 a of the guide rail 5. The groove 5a extends in the opening / closing direction, and guides the shutter curtain 4 to be movable in the opening / closing direction.

  As shown in FIG. 3, the shutter curtain 4 can be wound around a foil car 6. The opening 2 can be opened by winding the shutter curtain 4 around the wheel cage 6, and the opening 2 can be closed by feeding the shutter curtain 4 out of the foil cage 6. The winding and unwinding of the shutter curtain 4 may be performed manually or automatically by a driving device such as a motor. The wheel cage 6 is disposed in the case 7. The case 7 is attached to a wall or the like above the opening 2. The shutter device of this embodiment includes a shutter curtain 4, a guide rail 5, a wheel cage 6, and a case 7.

  Returning to FIG. 1, the waterproof device 1-1 of the opening includes a sheet 10, a holding unit 20, and a pressing member 16. The sheet 10 is installed in the opening 2 and has a width and a length capable of closing a region on the lower end side in the vertical direction of the opening 2. The shape of the sheet 10 is, for example, a rectangle. The sheet 10 has a water shielding property and can function as a waterproof sheet for the opening. Further, the sheet 10 has flexibility and may be stretchable. The material of the sheet 10 can be, for example, resin, rubber, or a cloth whose surface is coated with resin. The sheet 10 is preferably made of a material that can follow the deformation of the opening / closing body such as the shutter curtain 4 due to water pressure.

  The width of the sheet 10 is larger than the width of the shutter curtain 4. Moreover, it is preferable that the width | variety of the sheet | seat 10 is larger than the width | variety of the opening part 2, ie, the distance of the wall surface 3a and the wall surface 3b. The length of the seat 10 in the opening / closing direction is determined based on the water depth to be handled. That is, the total length of the sheet 10 is determined based on which range is covered and waterproofed from the lower end of the shutter curtain 4 toward the upper side in the vertical direction. In the following description, a portion to be covered with the sheet 10 in the shutter curtain 4 is referred to as a “predetermined portion” (see reference numeral 41 in FIG. 3). The predetermined portion 41 is a portion on the lower end side in the vertical direction of the shutter curtain 4.

  The holding unit 20 holds the sheet 10 with respect to the structure 1 at a position on the outdoor side of the shutter curtain 4. More specifically, the holding part 20 covers the predetermined part 41 of the shutter curtain 4 and the part adjacent to the predetermined part 41 of the structure 1 so as to close the lower end in the vertical direction of the opening 2. The sheet 10 is held. Further, the holding unit 20 holds the sheet 10 such that the lower end portion in the vertical direction of the sheet 10 extends toward the outdoor side along the floor surface 8. Thereby, the sheet | seat 10 can block | close the clearance gap which the shutter curtain 4 has, and the clearance gap between the shutter curtain 4 and the structure 1, and can suppress the water immersion to the indoor side.

  As shown in FIG. 2, the holding unit 20 includes a rail 21 and a bead 22. The rail 21 is attached to the wall surfaces 3a and 3b, respectively. The rail 21 may be fixed to the guide rail 5. The rail 21 has a C-shaped cross section, and slits are formed on surfaces facing each other. The rail 21 extends in the opening / closing direction, and is disposed in a range corresponding to the predetermined portion 41 of the shutter curtain 4. That is, the rail 21 is arranged corresponding to the range from the lower end of the shutter curtain 4 to the upper end of the predetermined portion 41. Note that the slits of the rail 21 may be formed on a surface facing the shutter curtain 4.

  The bead 22 can be inserted into the rail 21. The bead 22 has a C-shaped cross section, and both ends of the C-shape project outward. The bead 22 is formed of a lightweight and flexible material such as a resin material. Instead of this, the bead 22 may be formed of a metal material such as aluminum. The rail 21 and the bead 22 may be integrated.

  The zipper 11 is arrange | positioned at the both ends of the width direction of the sheet | seat 10, respectively. The zipper 11 is disposed at the edge of the sheet 10 and extends in the length direction (opening / closing direction) of the sheet 10. The zipper 11 has a cylindrical shape and can be inserted into the hollow portion of the bead 22. Since the slit width of the bead 22 is smaller than the outer diameter of the zipper 11, the zipper 11 is restricted from coming out of the bead 22 through the slit. In addition, the zipper 11 is not limited to a thing with a circular cross section, For example, a cross section may be a polygonal shape.

  When the sheet 10 is installed in the opening 2, first, the zipper 11 of the sheet 10 is inserted into the hollow portion of the bead 22. Next, as shown by an arrow Y1 in FIG. The width of the sheet 10 is larger than the width W of the opening 2 (see FIG. 2), in other words, the distance between the wall surface 3a and the wall surface 3b. For this reason, the sheet 10 has a slack in a state where both ends of the sheet 10 are held by the holding unit 20. In other words, the holding unit 20 holds the sheet 10 in a state where the sheet 10 has a slack, and allows the sheet 10 to bend toward the shutter curtain 4 side with respect to the holding unit 20 and contact the predetermined unit 41. Therefore, it is possible to place the sheet 10 along the guide rail 5 and the shutter curtain 4 and in contact with the guide rail 5 and the shutter curtain 4 while the sheet 10 is held by the holding unit 20. In addition, it is preferable that the sheet 10 has a slack enough to be in close contact with the shutter curtain 4, the guide rail 5, and the wall surfaces 3 a and 3 b in a state where the sheet 10 is held by the holding unit 20 and before water pressure is applied.

  The means for holding the sheet 10 against the structure 1 is not limited to that using the beads 22 and the rails 21. For example, the sheet 10 may be directly held by the rail 21 installed in the structure 1. Further, the sheet 10 may be fixed to the structure 1 with an adhesive tape, a hook-and-loop fastener, or the like. Alternatively, other known means that can hold the sheet 10 against the structure 1 may be used.

  As shown in FIG. 1, the sheet 10 is provided with a magnet 12. The magnet 12 is disposed at the upper end portion of the sheet 10. The upper end of the sheet 10 is fixed to the shutter curtain 4 by the attractive force of the magnet 12. The magnet 12 may be fixed to the sheet 10 in advance, but instead, a pocket portion may be provided in the sheet 10 and the magnet 12 may be placed in the pocket portion when the sheet 10 is installed. When the sheet 10 is attracted toward the shutter curtain 4 by the magnet 12, the sheet 10 is prevented from hanging down. Thereby, it can hold | maintain above the position of the water level which makes the upper end of the sheet | seat 10 aim.

  The means for holding the sheet 10 against the shutter curtain 4 is not limited to the magnet 12. For example, the sheet 10 may be fixed to the shutter curtain 4 with an adhesive tape, a hook-and-loop fastener, a suction cup, or the like.

  The length of the seat 10 in the opening / closing direction is longer than the length of the predetermined portion 41 of the shutter curtain 4 in the opening / closing direction. Therefore, in a state where the sheet 10 is held by the holding unit 20, the lower end portion in the vertical direction of the sheet 10 can be hung on the floor surface 8 and can be along the floor surface 8. The seat 10 is installed in a state where the lower end portion in the vertical direction of the seat 10 is extended toward the outdoor side along the floor surface 8. In other words, the sheet 10 is disposed such that the lower end in the vertical direction faces the floor surface 8 and is separated from the shutter curtain 4 toward the front end side. In the present specification, the lower end portion in the vertical direction of the sheet 10 and the portion extending along the floor surface 8 in a state where the sheet 10 is held by the holding unit 20 is referred to as a “sheet lower portion 13”.

  In the present embodiment, the pressing member 16 is placed on the lower sheet portion 13. The pressing member 16 presses the sheet 10 toward the structure 1. For example, the pressing member 16 presses the sheet 10 toward the floor surface 8. As shown in FIG. 1, the pressing member 16 is continuously disposed on the sheet lower portion 13 along the width direction of the opening 2. The pressing member 16 may be disposed without a gap or may be disposed with a predetermined gap between adjacent pressing members 16. The pressing member 16 is preferably rod-shaped or plate-shaped. The pressing member 16 according to the present embodiment is a plate-like flat bar. The pressing member 16 is made of, for example, metal, and has a mass and density capable of pressing the sheet lower portion 13 toward the floor surface 8 against buoyancy. The pressing member 16 is installed on the seat lower portion 13 after the seat lower portion 13 is disposed along the floor surface 8.

  As shown in FIGS. 1 and 3, the pressing member 16 is disposed in the vicinity of the lower end portion of the shutter curtain 4, that is, at a position where the sheet 10 is bent from a portion along the shutter curtain 4 to a portion along the floor surface 8. Has been. As a result, the sheet 10 can be kept in close contact with the floor surface 8 in the vicinity of the lower end of the shutter curtain 4.

  When the outdoor water volume increases due to flooding, guerrilla heavy rain, etc., the seat lower portion 13 first comes into contact with water. The sheet lower portion 13 is pressed toward the floor surface 8 by the water pressure and comes into close contact with the floor surface 8. Thereby, it is suppressed that water permeates from between the seat lower portion 13 and the floor surface 8. In addition, since the lower portion 13 of the sheet is pressed toward the floor surface 8 by the pressing member 16, water intrusion through the gap between the lower portion 13 and the floor surface 8 is more reliably suppressed even in the case of a low water level. Is done. The pressing member 16 according to the present embodiment is continuously provided along the width direction of the opening 2, that is, along the outer periphery of the opening 2. In the present embodiment, the plurality of pressing members 16 are continuously arranged along the width direction of the opening 2. Thereby, it is suppressed that a clearance gap arises between the sheet | seat lower part 13 and the floor surface 8. FIG. Further, the pressing member 16 can suppress the sheet lower portion 13 from being lifted by a water flow or the like. The sheet 10 can integrally cover the predetermined portion 41 and the floor surface 8 adjacent to the predetermined portion 41 by water pressure.

  Further, as shown by the white arrow in FIG. 2, the portion of the sheet 10 that covers the shutter curtain 4, the guide rail 5, and the wall surfaces 3a, 3b is directed toward the shutter curtain 4, the guide rail 5, and the wall surfaces 3a, 3b by water pressure. Pressed. Thereby, the sheet | seat 10 can cover the predetermined part 41 of the shutter curtain 4, the guide rail 5 adjacent to the predetermined part 41, and wall surface 3a, 3b integrally. The sheet 10 is pressed against the shutter curtain 4, the guide rail 5, and the wall surfaces 3 a and 3 b by being pressed by water pressure, and water flows between the sheet 10 and the shutter curtain 4, the guide rail 5, and the wall surfaces 3 a and 3 b. Infiltration can be suppressed.

  Moreover, the sheet | seat 10 suppresses the flooding to the indoor side through these clearance gaps by plugging the clearance gap between the shutter curtain 4 and the guide rail 5, and the clearance gap between the guide rail 5 and wall surface 3a, 3b with water pressure. Can do. Moreover, the sheet | seat 10 can suppress the water immersion to the indoor side through this clearance gap by plugging the clearance gap between the mutually adjacent slats 4a and 4a. In addition, the sheet 10 closes the gap between the predetermined portion 41 of the shutter curtain 4 and the floor surface 8 adjacent to the predetermined portion 41 by water pressure, so that the seat 10 moves to the indoor side via the gap between the shutter curtain 4 and the floor surface 8. Infiltration of water can be suppressed.

  Since the sheet 10 is pressed against the shutter curtain 4 and the like by the water pressure, the adhesion to the shutter curtain 4 and the like increases as the water level increases, and the closing property that closes each gap increases. Therefore, the sheet | seat 10 can suppress the water penetration performance according to a water level, and can suppress the inundation to an indoor side appropriately.

  Further, since the sheet 10 is held by the holding unit 20 in a state having a slack in advance, the sheet 10 can be brought into close contact with the shutter curtain 4, the guide rail 5 and the like promptly by water pressure as the water level increases. Further, since it has a slack, it can be appropriately deformed and bent corresponding to the shape of the gap of each part such as the gap between the shutter curtain 4 and the guide rail 5, and each gap can be closed quickly and appropriately. it can.

  From the viewpoint of improving waterproofness, the pressing member 16 is preferably placed on the lower end 15 a of the portion 15 that covers the wall surface of the seat 10. The sheet 10 according to the present embodiment integrally includes a predetermined portion 41, a floor surface 8 adjacent to the predetermined portion 41, and wall surfaces 3a and 3b adjacent to the predetermined portion 41 and facing each other in the width direction of the opening 2. It covers something. Of the seat 10, the length in the opening / closing direction of the portion 15 covering the wall surface is larger than the length of the holding portion 20. The portion 15 that covers the wall surface can integrally cover the wall surfaces 3 a and 3 b and the floor surface 8 in a state where the sheet 10 is held by the holding unit 20. The lower end 15 a of the portion 15 that covers the wall surface is overlaid on the seat lower portion 13.

  The portion 15 that covers the wall surface integrally covers the wall surfaces 3a, 3b and the floor surface 8, so that water from the corner A where the floor surface 8 and the wall surfaces 3a, 3b intersect is suppressed. Moreover, since the pressing member 16 is mounted on the lower end 15a of the portion 15 that covers the wall surface, the flooding from the corner A is further suppressed.

  From the viewpoint of improving waterproofness, it is preferable that the pressing members 16 are continuously arranged in the width direction of the opening 2 so that the end portions thereof are in contact with each other. In this way, the gap between the seat lower portion 13 and the floor surface 8 can be further reduced. The pressing member 16 is preferably provided continuously from one end to the other end in the width direction of the opening 2. For example, as shown in FIG. 4, it is preferable that the pressing member 16 is disposed continuously from one wall surface 3 a to the other wall surface 3 b and in contact with the end portions.

  The pressing member 16 disposed at the end in the width direction of the opening 2 is preferably installed so as to press the portion 15 covering the wall surface of the sheet 10 toward the wall surfaces 3a and 3b by the end portion. For example, it is preferable that the pressing member 16 arranged closest to the wall surface 3b is installed so as to press the sheet 10 toward the wall surface 3b by an end portion on the wall surface 3b side. Thereby, the clearance gap between the sheet | seat 10 and wall surface 3a, 3b can be decreased, and the permeation of the water to the indoor side can be suppressed.

  In the present embodiment, the plurality of pressing members 16 are disposed in the lower sheet portion 13, but one pressing member 16 may be provided. For example, the sheet lower portion 13 may be pressed toward the floor surface 8 by a single pressing member 16 having the same length as the total extension of the plurality of pressing members 16.

  An instruction manual or an instruction manual may be displayed on the sheet 10. For example, if a list of components included in the waterproof device 1-1 of the opening and the installation method / installation procedure are printed on the sheet 10, the installation work can be quickly performed in an emergency such as a flood. It becomes.

  The pressing member 16 may be a ballast (sandbag) instead of the plate-like flat bar. The ballast is built in the sheet 10, for example. The ballast is, for example, built in between the two stacked sheets 10, but is not limited thereto, and may be fixed to the surface of the sheet 10 by adhesion, sewing, or the like. The ballast can be pre-arranged in the lower seat portion 13. The installation position of the ballast can be, for example, the same position as the position indicated by the dashed ellipse in FIG. 1, that is, the position where the flat bar is placed.

  In the present embodiment, the lower end 15a of the portion 15 that covers the wall surface is separated from the seat lower portion 13, but the present invention is not limited to this. For example, the lower end 15 a of the portion 15 that covers the wall surface may be integrated with the seat lower portion 13. In this case, when the sheet 10 is installed in the opening 2, it is preferable to fold the connecting portion between the lower end 15 a and the sheet lower part 13 and overlap the sheet lower part 13. It is preferable that the pressing member 16 is placed on a folded portion that is overlaid on the seat lower portion 13 and presses the folded portion toward the floor surface 8.

[First Modification of First Embodiment]
A first modification of the first embodiment will be described. FIG. 5 is a perspective view showing the installation state of the pressing member according to the first modification of the first embodiment, and FIG. 6 is a cross-sectional view showing the installation state of the pressing member according to the first modification of the first embodiment. is there. In the pressing member 16 according to this modification, the difference from the pressing member 16 of the first embodiment is that the pressing member 16 can be deformed according to the shape of the structure 1.

  As shown in FIGS. 5 and 6, the pressing member 16 includes a main body 16a and a deforming portion 16b. The main body 16a is a flat bar similar to the pressing member 16 of the first embodiment, and can be made of a material having a relatively large specific gravity such as metal or a material having high rigidity. The deformation portion 16b is capable of deformation such as elastic deformation and plastic deformation, and is made of rubber, for example. The deformation portion 16b is formed in a plate shape, and one surface of the main body 16a and one surface of the deformation portion 16b are fixed by adhesion or the like. As shown in FIG. 6, the pressing member 16 is placed with the surface 16 e opposite to the main body 16 a side (hereinafter referred to as “installation surface”) 16 e of the deforming portion 16 b facing the sheet 10.

  When the pressing member 16 is installed on the seat lower portion 13, the pressing member 16 is placed on the seat lower portion 13 with the installation surface 16 e facing downward. When the deforming portion 16 b of the present embodiment is placed on the sheet lower portion 13, the deforming portion 16 b is deformed according to the shape of the floor surface 8 due to the weight of the pressing member 16. For example, when the floor surface 8 is uneven as shown in FIG. 6, the deforming portion 16 b is deformed according to the unevenness of the floor surface 8 by the weight of the pressing member 16. The deforming portion 16b is deformed into a concave shape corresponding to the shape of the convex portion of the floor surface 8, and is deformed into a convex shape corresponding to the shape of the concave portion of the floor surface 8. Thereby, when the sheet lower part 13 is installed on the floor surface 8 having unevenness, the pressing member 16 presses the sheet lower part 13 toward the concave part or the convex part of the floor surface 8, and the sheet lower part 13 and the floor surface 8 are The gap can be reduced.

  Further, when the floor surface 8 is curved, the pressing member 16 can be deformed according to its curved shape by its own weight. Therefore, the pressing member 16 according to the present modification can be easily installed, can suppress the seat lower portion 13 from being lifted from the floor surface 8, and can prevent water from entering the indoor side.

  In addition, the deformation | transformation part 16b deform | transforms according to the shape of a surface by being pressed with respect to surfaces, such as the floor surface 8, etc., and maintains the shape, even after the pressing force by a user is lost, Also good. As an example, the deformable portion 16b may be made of a material that can maintain its shape due to its own weight even after the pressing force by the user is lost.

  In the present modification, a part of the pressing member 16 is the deforming portion 16b, but instead, the entire pressing member 16 may be the deforming portion 16b.

[Second Modification of First Embodiment]
A second modification of the first embodiment will be described. FIG. 7 is an explanatory view of a gap at the corner, FIG. 8 is a perspective view showing an installation state of a pressing member according to a second modification of the first embodiment, and FIG. 9 is a second modification of the first embodiment. It is sectional drawing which shows the installation state of the press member which concerns on. In the pressing member 16 according to this modification, the difference from the pressing member 16 according to the first modification of the first embodiment is that a deforming portion is provided at the end.

  As shown in FIG. 7, at the corner A where the wall surfaces 3 a, 3 b and the floor surface 8 intersect, a gap is likely to occur between the portion 15 that covers the wall surface of the sheet 10. If water pressure is applied to the sheet 10, the gap is reduced by being pressed toward the corner A, but if the water level is low and the water pressure applied to the sheet 10 is not sufficient, the water immersion from the gap in the corner A cannot be ignored. There is sex.

  Since the pressing member 16 according to this modified example has a deformed portion at the end portion, it is possible to reduce the gap of the corner portion A and suppress the flooding. As shown in FIGS. 8 and 9, the pressing member 16 has an end deforming portion 16 c. The end deforming portion 16 c is disposed at one end in the longitudinal direction of the pressing member 16, and faces the wall surfaces 3 a and 3 b in the width direction of the opening 2 when installed on the seat lower portion 13. The end deformation portion 16c is capable of deformation such as elastic deformation and plastic deformation, and is made of rubber, for example. The end deforming portion 16c can be deformed according to the shape of the wall surfaces 3a and 3b by being pressed toward the wall surfaces 3a and 3b. The end deforming portion 16c is formed in a rectangular plate shape, and is fixed to the end surfaces of the main body 16a and the deforming portion 16b by adhesion or the like. In addition, the deformation | transformation part 16b and the edge part deformation | transformation part 16c may be formed integrally.

  The pressing member 16 having the end deforming portion 16c has a surface (hereinafter referred to as a “pressing surface”) 16f opposite to the main body 16a side of the end deforming portion 16c facing the wall surfaces 3a and 3b and an installation surface 16e. Is placed on the lower portion 13 of the seat. The pressing member 16 is preferably installed so as to press the sheet 10 toward the wall surfaces 3a and 3b by the end deforming portion 16c. The end deforming portion 16c is pressed toward the wall surfaces 3a and 3b and deforms according to the shape of the wall surfaces 3a and 3b, so that the gap between the sheet 10 and the wall surfaces 3a and 3b or the gap between the sheet 10 and the corner portion A is obtained. Inundation is suppressed.

  As shown in FIG. 9, the end deforming portion 16c has a corner portion 16d. Since the pressing member 16 has the corner portion 16d, it is possible to reduce the gap at the corner portion A and suppress flooding. The corner portion 16 d is a corner portion corresponding to the corner portion A when placed on the sheet lower portion 13, that is, a corner portion formed by the lower surface and the end surface of the pressing member 16. The shape of the corner portion 16d corresponds to the shape of the corner portion A. In the present embodiment, the corner A is a right angle, and the corner 16d is formed at a right angle correspondingly. The pressing member 16 is installed with the sheet 10 interposed between the corner portion 16d and the corner portion A. When the pressing member 16 is installed by pressing the end deforming portion 16c toward the wall surfaces 3a and 3b, the corner portion 16d presses the sheet 10 toward the corner portion A. Thereby, the clearance gap between the corner A and the sheet | seat 10 reduces, and even if it is a case where a water level is low, the water immersion from the corner A is suppressed appropriately.

  In order to press and install the end deforming portion 16 c toward the wall surfaces 3 a and 3 b, for example, the total extension of the pressing member 16 may be made larger than the width W of the opening 2. In this way, when the pressing member 16 is continuously arranged from one end to the other end in the width direction of the opening 2 as shown in FIG. 4, the end deforming portion 16c is in a compressed state. Therefore, the sheet | seat 10 can be pressed toward wall surface 3a, 3b and the corner part A by the edge part deformation | transformation part 16c, and adhesiveness can be improved.

  Depending on the configuration of the shutter device, there may be no wall surface on which the sheet 10 can be pressed. FIG. 10 is an explanatory diagram of an installation method for pressing the sheet toward the guide rail by the pressing member. As shown in FIG. 10, the holding unit 20 may be attached to the guide rail 5. In this case, waterproofness can be improved by pressing the sheet 10 toward the guide rail 5 by the pressing member 16.

  As shown in FIG. 10, the pressing member 16 is installed on the lower portion 13 of the sheet so as to press the sheet 10 toward the guide rail 5 by the main body 16 a and the end deforming portion 16 c. Thereby, the clearance gap between the sheet | seat 10 and the guide rail 5 is reduced. Further, the gap at the corner where the guide rail 5 and the floor surface 8 intersect is reduced. Therefore, the gap near the floor surface 8 can be made as small as possible to suppress inundation in a low water level state.

  FIG. 11 is a diagram illustrating another example of the pressing member that presses the sheet toward the guide rail. The pressing member 16 shown in FIG. 11 has a deforming portion 16g that protrudes in a direction orthogonal to the longitudinal direction with respect to the main body 16a. The deformation portion 16g is capable of deformation such as elastic deformation and plastic deformation, and is made of rubber, for example. The deformation portion 16g is disposed on the side surface of the end portion of the pressing member 16. The deforming portion 16g may be formed by projecting part of the end deforming portion 16c or the deforming portion 16b. The pressing member 16 is installed so as to press the sheet 10 toward the guide rail 5 by the deforming portion 16g. In addition, in the pressing member 16 shown in FIG. 11, the main body 16a may be replaced with a flat bar and may be angle steel.

[Third Modification of First Embodiment]
As shown in FIG. 12, the end portion in the width direction of the sheet lower portion 13 may be subjected to end processing in advance according to the width of the opening 2. FIG. 12 is a diagram illustrating an end portion in the width direction of the sheet according to the third modified example of the first embodiment. When the width of the sheet lower portion 13 is larger than the width of the opening 2, it is necessary to appropriately treat both end portions 13 a in the width direction in order to make the sheet lower portion 13 adhere to the floor surface 8. Here, when the both ends 13a of the sheet lower portion 13 are not subjected to any treatment and the both ends 13a of the sheet lower portion 13 are set to fit in the field at the time of installation, the sheet 10 can be wrinkled by a crease or the like. There is a fear. In this case, it becomes easy for water to enter from a gap due to a generated wrinkle or the like, which may lead to a decrease in water stopping performance. Moreover, the accommodation of the sheet | seat 10 changes with installers, and there exists a possibility of affecting a water stop performance.

  In this modification, both end portions 13a of the sheet lower portion 13 are folded in advance. Both end portions 13a are fixed in a state of being folded back to the lower surface side of the seat lower portion 13, that is, the side facing the floor surface 8 at the time of installation. The fixing method may be a method such as adhesion or sewing with a double-sided tape or the like. Thereby, it becomes possible to install the sheet lower portion 13 on the floor surface 8 without wrinkles or the like. The width of the sheet lower portion 13 matches the width of the opening 2 in a state where both end portions 13a are folded back. Thereby, it is suppressed that a clearance gap arises between the sheet | seat lower part 13 and wall surface 3a, 3b. Note that both end portions 13 a of the seat lower portion 13 may be folded back to the upper surface side of the seat lower portion 13.

  Since the sheet lower portion 13 is previously folded according to the fit of the corner, it is easy to adjust the attachment of the sheet 10 performed on site. There is an advantage that standard installation is possible, the installation time is shortened, and the water stop performance is improved.

  Note that both end portions of the sheet lower portion 13 may be cut in advance in accordance with the width of the opening 2 instead of having both end portions 13 a of the sheet lower portion 13 folded. In this case, when the wall surfaces 3a and 3b are uneven, both end portions of the sheet lower portion 13 may be cut into a shape matching the unevenness. In addition, the end portion processing of the both end portions 13a of the sheet lower portion 13 can be performed so that the amount of adjustment work on site can be reduced or the adjustment work can be made unnecessary. That is, other means for forming both end portions 13a in advance in accordance with the shapes and irregularities of the wall surfaces 3a, 3b, the guide rail 5, the rail 21, etc. may be employed.

[Fourth Modification of First Embodiment]
A fourth modification of the first embodiment will be described. FIG. 13 is a diagram illustrating a sheet according to a fourth modification of the first embodiment. The installation position of the pressing member 16 may be displayed on the sheet 10. This display can be, for example, a band-shaped mark.

  In addition, the method of pressing the sheet lower portion 13 toward the floor surface 8 may be based on magnetic force. For example, it is possible to embed an iron plate or the like in advance in the floor surface 8 and press the sheet lower portion 13 toward the iron plate by the magnetic force of the magnet.

  In addition, a mark 17 serving as a guide for alignment in the opening / closing direction is displayed on the sheet 10. The mark 17 indicates the lower end of the range along the shutter curtain 4 of the sheet 10 held by the holding unit 20. That is, the mark 17 indicates a position corresponding to the lower end of the shutter curtain 4 on the sheet 10. Positioning in the opening / closing direction of the sheet 10 is performed based on the mark 17, thereby suppressing the occurrence of cover leakage on the lower end side of the sheet 10.

[Fifth Modification of First Embodiment]
A fifth modification of the first embodiment will be described. FIG. 14 is a diagram illustrating a waterproof device 1-1 for an opening according to a fifth modification of the first embodiment. The pressing member 18 according to this modification has water absorption. The pressing member 18 is, for example, a rod-like or plate-like member, and its length corresponds to the width of the sheet lower portion 13. Accordingly, the pressing member 18 can suppress lifting of the sheet 10 by pressing from one end to the other end of the sheet lower portion 13 in the width direction. The pressing member 18 is attached to the sheet 10 in advance.

  The pressing member 18 is made of a material that sucks in water, such as sponge, felt, cloth, or the like. Since these materials are easy to fold together with the sheet 10 and light when dried, convenience in storage, transportation, installation, and the like is improved. In addition, the raw material of the press member 18 is not limited to what was illustrated, Another well-known raw material may be used.

  From the viewpoint of suppressing lifting of the edge portion of the sheet lower portion 13, it is preferable to edge the sheet lower portion 13 with the pressing member 18. The pressing member 18 is disposed, for example, on the most outdoor side edge 13 b in the seat lower portion 13. FIG. 15 is a diagram illustrating an example of the arrangement of the pressing members 18. The pressing member 18 may be disposed on the edge 13c at the end in the width direction in addition to the edge 13b on the outdoor side. The pressing member 18 shown in FIG. 15 has a first portion 18a extending along the edge portion 13b on the outdoor side and a second portion 18b extending along the edge portions 13c at both ends in the width direction. . The first portion 18a and the second portion 18b are integrally formed. The second portion 18b is disposed in a predetermined range on the front end side at the edge 13c at both ends in the width direction. As described above, the pressing member 18 is disposed so as to press the corner of the sheet lower portion 13, so that the lifting of the sheet lower portion 13 is effectively suppressed.

[Sixth Modification of First Embodiment]
A sixth modification of the first embodiment will be described. In the present modification, a part of the sheet 10 is sandwiched between the shutter curtain 4 and the floor surface 8 and is pressed toward the floor surface 8 by the shutter curtain 4. Thereby, the lift of the sheet lower portion 13 can be suppressed by using the shutter curtain 4 instead of the weight. 16, FIG. 17, and FIG. 18 are cross-sectional views showing the seat 10 according to this modification.

  In the seat 10 shown in FIG. 16, a part of the front end side of the seat lower portion 13 is folded back toward the indoor side. A portion 13e at the front end side of the bent portion 13d in the seat lower portion 13 is installed so as to extend to the indoor side from the seat plate 4b of the shutter curtain 4. For example, in a state where the shutter curtain 4 is moved slightly in the opening direction from the fully closed position, the tip end portion 13e is inserted between the seat plate 4b and the floor surface 8. Thereafter, the shutter curtain 4 is moved to the fully closed position and presses the tip end portion 13e toward the floor surface 8.

  In this way, the front end portion 13e is pressed by the shutter curtain 4, so that the sheet lower portion 13 is prevented from being lifted. Further, the sheet lower portion 13 is sandwiched between the shutter curtain 4 and the floor surface 8 to close the gap between the shutter curtain 4 and the floor surface 8. Thereby, inundation through the gap between the shutter curtain 4 and the floor surface 8 is suppressed.

  A sheet 10 shown in FIG. 17 is obtained by connecting a first sheet 25 and a second sheet 26. The first sheet 25 is a sheet that is disposed opposite to the shutter curtain 4 and extends in the opening and closing direction. The second sheet 26 is a sheet disposed opposite to the floor surface 8. The first sheet 25 is connected to the upper surface of the second sheet 26. In the second seat 26, the portion 26 a on the outdoor side of the first seat 25 functions as the seat lower portion 13. In the second sheet 26, the portion 26 b on the indoor side of the first sheet 25 is disposed so as to be sandwiched between the shutter curtain 4 and the floor surface 8.

  A sheet 10 shown in FIG. 18 is obtained by connecting a first sheet 27 and a second sheet 28. The first sheet 27 has a portion 27 b disposed opposite to the shutter curtain 4 and a portion 27 c disposed opposite to the floor surface 8. A portion 27 c arranged opposite to the floor surface 8 functions as the seat lower portion 13. The first sheet 27 and the second sheet 28 are connected such that one ends 27a and 28a in the length direction are overlapped with each other. Specifically, the leading end 27 a of the sheet lower portion 13 of the first sheet 27 and the leading end 28 a of the second sheet 28 are overlapped. The second sheet 28 is connected to the lower surface side with respect to the first sheet 27.

  The second sheet 28 has a floor surface such that an end portion 28 a overlapped with the first sheet 27 is located on the outdoor side of the shutter curtain 4 and the other end 28 b is located on the indoor side of the shutter curtain 4. 8 are arranged opposite to each other. The second sheet 28 is sandwiched between the shutter curtain 4 and the floor surface 8 and pressed toward the floor surface 8. Since the first sheet 27 and the second sheet 28 are overlapped and connected, the floating of the end portions 27a and 28a on the outdoor side is suppressed.

[Seventh Modification of First Embodiment]

The pressing member 50 is preferably made of a lightweight material so that it can be handled easily. The main body 50a is a flat bar and can be made of a material having high rigidity. The deformable portion 50b is capable of deformation such as elastic deformation and plastic deformation, and is made of rubber, for example. The deformation portion 50b is formed in a plate shape, and one surface of the main body 50a and one surface of the deformation portion 50b are fixed by adhesion or the like. The pressing member 50 is installed with the installation surface 50c opposite to the main body 50a side of the deforming portion 50b facing the sheet 10.

  The pressing member 50 is pressed toward the wall surfaces 3a and 3b by the pressing device 51, for example. The pressing device 51 has a main body 52 and a fixing portion 53. The main body 52 is a member having a right triangle shape in plan view. The main body 52 is fixed to the floor surface 8 by the fixing portion 53 in a state where the pressing member 50 is pressed toward the wall surfaces 3 a and 3 b by the one side 52 a that sandwiches the right angle. The fixing portion 53 fixes the main body 52 to the floor surface 8 by, for example, a combination of bolts and nuts. The pressing member 50 and the pressing device 51 according to this modification can function as a holding unit that holds the sheet 10.

  Note that the means for pressing the pressing member 50 toward the wall surfaces 3a and 3b is not limited to the exemplified one. For example, the pressing member 50 may be pressed toward the wall surfaces 3a and 3b by a tension rod. Further, the pressing member 50 may be attracted toward the wall surfaces 3a and 3b by a magnetic force.

[Second Embodiment]
A second embodiment will be described with reference to FIG. In the second embodiment, the same reference numerals are given to components having the same functions as those described in the above embodiment, and duplicate descriptions are omitted. FIG. 23 is a diagram illustrating a support member of the waterproof device 2-1 for an opening according to the present embodiment. The waterproof device 2-1 for the opening portion of the present embodiment is different from the waterproof devices 1-1, 1-2, and 1-3 for the opening portion of the first embodiment in that it includes a support member that supports the opening / closing body. Is a point. The strength of the shutter device is designed to satisfy the wind pressure resistance performance, but the water pressure associated with the shutter device during floods such as guerrilla heavy rain is much higher than the wind pressure. For this reason, when installing the sheet | seat 10 and stopping water, it is preferable to be able to support the shutter curtain 4 against the force by water pressure.

  As shown in FIG. 23, a mounting hole 36 is provided on the floor 8 on the indoor side of the shutter curtain 4. The attachment holes 36 are arranged along the thickness direction of the shutter curtain 4. The support member 37 has a protrusion 37 b corresponding to the contact portion 37 a and the attachment hole 36.

The support member 37 has a triangular shape, and the contact portion 37a is one side thereof. The protrusion 37b is disposed on the other side and protrudes outward. The support member 37 is, for example, a right triangle, and in this case, one side of the contact portion 37a and one side having the protrusion 37b are orthogonal to each other. The protrusion 37b is inserted into the mounting hole 36 and restricts the support member 37 from moving in the thickness direction.

  The support member 37 is positioned by the protrusion 37b and the attachment hole 36, and is installed, for example, so as to face the seat plate 4b of the shutter curtain 4 in the thickness direction. When the shutter curtain 4 bends indoors due to water pressure applied to the shutter curtain 4 from the outdoor side, the seat plate 4 b comes into contact with the contact portion 37 a of the support member 37. Thereby, the further deformation | transformation of the seat board 4b is suppressed. By suppressing the deformation of the seat plate 4b, the deformation of each slat 4a connected to the seat plate 4b is also suppressed. That is, the support member 37 suppresses deformation of the shutter curtain 4 by supporting the shutter curtain 4 against the force of water pressure from the outdoor side.

  The support member 37 can suppress the deformation of the shutter curtain 4 by supporting the seat plate 4 b and can prevent the shutter curtain 4 from coming out of the guide rail 5. Further, the support member 37 can suppress water immersion caused by the deformation of the shutter curtain 4.
