Description

  The present invention relates to a water stop device.

  In the event of a typhoon or guerrilla rain, facilities such as subway stations and underground parking lots may be flooded. Conventionally, sandbags were piled up at entrances and exits of facilities to reduce damage caused by flooding. However, preparation of the sandbags and stacking of the sandbags at the doorway require a lot of work time. In addition, sandbags may not provide a sufficient water stopping effect in some cases. Therefore, in recent years, a water stoppage measure using a water stoppage plate instead of a sandbag has been studied (for example, see Patent Document 1).

JP-A-2006-223149

  The device disclosed in Patent Literature 1 has a water stop plate attached to an entrance of a facility. By using the water stoppage plate, water stoppage measures at the entrance and exit of the facility can be performed in a short time. However, when using this type of water stoppage plate, it is necessary to use a water stoppage plate having the same length as the width of the entrance. Therefore, for example, when the frontage of the doorway is wide, a water stoppage plate having high rigidity according to the length is required. Such a water stop plate has a high manufacturing cost and is inferior in portability.

  In addition, when using a plurality of water stoppage plates shorter than the width of the entrance, it is necessary to install a column for supporting the waterstop at the entrance. However, the installation of the pillars at the entrance requires a large-scale external construction work, which increases the cost of installing the water stoppage plate. Also, depending on the facility, it may be difficult to permanently install the columns.

  The present invention has been made under the above circumstances, and provides a water stoppage plate that is low in cost, has excellent portability, and is easy to install.

  In order to solve the above-mentioned problem, a water stop device according to an embodiment is a water stop device used at an entrance of a facility, and includes a first water stop plate and a second water stop plate, and the first water stop device. A holding mechanism for holding one end of a plate and one end of the second water stop plate, and a first water stop plate provided on both sides of the entrance and exit so as to project the outside of the facility; A support member that supports the second water blocking plates at a predetermined angle.

  The water stop device 100 according to the embodiment will be described with reference to the drawings. In the description, an XYZ coordinate system including an X axis, a Y axis, and a Z axis that are orthogonal to each other will be used.

  FIG. 1 is a perspective view of a water stop device 100 installed in a building H. The building H is a structure that forms an entrance F such as a subway station, an underground shopping mall, or an underground parking lot. The water stop device 100 is provided at the entrance / exit F of the building H, and suppresses inundation into the inside of the building H. As shown in FIG. 1, the water stopping device 100 includes a water stopping unit 1 and a guide block 30.

  FIG. 2 is a perspective view of the water stop unit 1. As shown in FIG. 2, the water stopping unit 1 has a pair of water stopping plates 2 and a fixing member 10. The water blocking plate 2 is a member whose longitudinal direction is the X-axis direction. The water stop plate 2 is made of, for example, fiber-reinforced plastic or FRP (Fiber-Reinforced Plastics), etc. The length (dimension in the X-axis direction) of the water stop plate 2 is the width of the frontage of the entrance F of the building H. The dimensions of the water blocking plate 2 are, for example, 2000 mm in length, 500 mm in height, and 80 mm in thickness.

  As can be seen with reference to FIG. 2, the pair of water blocking plates 2 are connected by two hinges 7 so as to be able to move up and down around an axis parallel to the Z axis. The hinge 7 is made of two metal members that are detachable from each other. Each component is fixed to the water stop plate 2. For this reason, it is also possible to separate the water blocking plate 2 that is rotatably connected by the hinge 7. As the hinge 7, a release hinge, a hook hinge, or the like can be used.

  FIG. 3 is a plan view of the water stop unit 1 as viewed from above (+ Z side). As shown in FIG. 3, the pair of waterproof plates 2 has side surfaces facing the other waterproof plates 2 inclined at about 15 degrees with respect to the Y axis. Thereby, the range in which the pair of water blocking plates 2 is raised and lowered is regulated. As shown in FIG. 3, the water blocking plate 2 is moved from the state where the angle formed by the two water blocking plates 2 becomes θ1 (= 150 degrees), as shown in FIG. Rotate around the hinge 7 until it is parallel and overlapped.

  As shown in FIG. 3, packings 4 and 5 as water-stop members are adhered to both ends of the water-stop plate 2 in the X-axis direction. As shown in FIG. 2, the packings 4 and 5 are attached so as to cover the entire outer edges of both ends of the water blocking plate 2. The packings 4 and 5 are made of, for example, natural rubber, oil-resistant rubber, or the like. The packing 4 is provided over a side surface in the X-axis direction of the water blocking plate 2 and a surface on the + Y side. The packing 5 is provided over the side surface in the X-axis direction of the water blocking plate 2 and the surface on the −Y side.

  FIG. 5 is a perspective view of the water blocking plate 2. As shown in FIG. 5, a packing 3 as a water stopping member is adhered to a lower surface of the water stopping plate 2. The packing 3 is provided from the −X side end to the + X side end of the lower surface of the water blocking plate 2. A concave portion 3a that is depressed in the + Y direction is formed on the −Y side surface of the packing 3. The concave portion 3 a is a groove provided from the −X side end to the + X side end of the packing 3. The water blocking plate 2 is arranged so that the recess 3a faces the outside of the building H. In this state, the packing 3 comes into close contact with the floor surface G without any gap due to the weight of the water blocking plate 2. 5 and 2, the lower ends of the packings 4, 5 are in close contact with the side surface of the packing 3 in the X-axis direction.

  As shown in FIG. 2, a wedge 8 is provided on the −Y side surface of the water blocking plate 2. The wedge 8 is arranged at a position facing the + Y side portion of the packing 4 via the water blocking plate 2. The wedge 8 is made of a metal such as iron, for example, and is fixed to the water blocking plate 2 by, for example, screws. As shown in FIG. 5, the −Y side surface of the wedge 8 is inclined with respect to the front surface (−Y side surface) of the water blocking plate 2. Specifically, the surface on the −Y side of the wedge 8 is inclined so that the distance from the front surface of the water blocking plate 2 decreases as approaching the packing 4.

  As shown in FIG. 2, a pair of recesses 6 are formed at the upper end of the −Y side surface of the water blocking plate 2. The concave portion 6 can be hung by a finger, and functions as a handle of the water stop plate 2 when the water stop plate 2 is carried. Instead of the concave portion 6, a through-hole that penetrates the water blocking plate 2 may be provided.

  As shown in FIG. 2, the fixing member 10 is a component that is mounted over both the pair of waterproof plates 2 when the pair of waterproof plates 2 is opened until the pair reaches the angle θ1. When the fixing member 10 is fixed to the water blocking plate 2, the angle formed by the pair of water blocking plates 2 is fixed.

  FIG. 6 is a plan view of the fixing member 10. FIG. 7 is a view showing an AA cross section of the fixing member 10 shown in FIG. The fixing member 10 includes a base plate 15 shaped into a V-shape in plan view, two side plates 14 provided along outer edges of both ends of the base plate 15 in the Y-axis direction, and a handle 12 fixed to the base plate 15. It is a member which consists of.

  The base plate 15 is made of a metal such as iron. Each of the two side plates 14 is also made of metal and is welded to the base plate 15. The two side plates 14 are parallel to each other. Each side plate 14 has a cushioning member 13 bonded to a surface facing the other side plate 14. The buffer member 13 is made of, for example, sponge rubber. As shown in FIG. 7, the distance D <b> 1 between the side plates 14 is slightly larger than the thickness of the water stop plate 2. The distance D2 between the two cushioning members 13 attached to the side plate 14 and facing each other is slightly smaller than the thickness of the water blocking plate 2.

  The handle 12 is a U-shaped member, and is welded to the upper surface of the base plate 15. The fixing member 10 can be handled by holding the handle 12. As shown in FIG. 2, the fixing member 10 is attached to a boundary between the two waterproof plates 2 that are opened and closed.

  Returning to FIG. 1, the guide block 30 is a member provided on a wall or the like constituting a frontage of the entrance F provided in the building H. FIG. 8 is a diagram illustrating the pair of guide blocks 30 together with the wall W of the building H. As shown in FIG. 8, the guide block 30 is embedded in a wall W that defines the entrance F. Mortar or the like is appropriately coked between the guide block 30 and the wall W.

  The guide block 30 is made of a material such as iron or stainless steel, and is a member whose longitudinal direction is the Z-axis direction. The guide block 30 is, for example, 600 mm in height, 180 mm in the Y-axis direction, and 100 mm in the X-axis direction. The guide block 30 has grooves 35 formed on surfaces facing each other. The groove 35 is formed from the upper end to the lower end of the guide block 30.

  FIG. 9 is an enlarged view of the guide block 30. As shown in FIG. 9, the groove 35 is defined by three inner wall surfaces 35a, 35b, 35c. The inner wall surface 35a is inclined by θ2 (= 15 degrees) with respect to the YZ plane, and the inner wall surfaces 35b and 35c are inclined by θ2 (= 15 degrees) with respect to the XZ plane. The inner wall surface 35c is formed with a projection 32 protruding toward the inner wall surface 35b. The tip of the projection 32 is shaped into a curved surface or a spherical surface. The protrusion 32 is made of, for example, metal or resin.

  One end of the water blocking plate 2 is inserted into the grooves 35 of the two guide blocks 30 configured as described above. When the water blocking plate 2 is inserted into the groove 35 of the guide block 30, the wedge 8 provided on the water blocking plate 2 comes into contact with the projection 32 of the guide block 30. Thus, when the water stop plate 2 is inserted, the water stop plate 2 is pressed against the inner wall surface 35 b that defines the groove 35 of the guide block 30 by the cooperation of the wedge 8 and the projection 32. As a result, the packing 4 provided on the water blocking plate 2 comes into close contact with the inner wall surface 35b.

  As shown in FIG. 8, by inserting the two water blocking plates 2 of the water blocking unit 1 into the grooves 35 of the guide blocks 30 provided on both sides of the entrance F, the water blocking unit 1 becomes the building H Is held in a state of protruding outside. In this state, as shown in FIG. 5, the packing 3 provided on the lower surface of the water blocking plate 2 is in close contact with the floor surface G. Then, as shown in FIG. 3, the packings 5 provided on each of the pair of waterproof plates 2 are in close contact with each other. Further, as shown in FIG. 9, the packing 4 provided on the side surface of the water blocking plate comes into close contact with the inner wall surfaces 35 a and 35 b constituting the groove 35 of the guide block 30. Thereby, the entrance F of the building H is made watertight by the water stop device 100.

  In the water stopping device 100 configured as described above, the water stopping unit 1 is usually stored in a state where it is detached from the guide block 30, for example, in a folded state as shown in FIG. 4. When using the water stopping unit 1, first, as shown in FIG. 3, the water stopping plates 2 are rotated and deployed. Then, as shown in FIG. 8, while adjusting the angle of the water stop plate 2, one end of the water stop plate 2 is moved horizontally and inserted into the groove 35 of the guide block 30. In this state, the water stop plate 2 does not rotate with respect to the force in the direction indicated by the arrow P, but does not rotate in the direction opposite to the direction indicated by the arrow P. 2 rotates in the closing direction. Therefore, as shown in FIG. 2, the fixing member 10 is mounted on the water blocking plate 2.

  As shown in FIG. 10, when the fixing member 10 is mounted, the water blocking plate 2 is sandwiched by the side plates 14 via the buffer member 13 of the fixing member 10. Thereby, the rotation of the water stop plate 2 is restricted, and the water stop unit 1 is firmly fixed to the guide block 30. For this reason, for example, even if a person who tries to go outside from the entrance F of the building H accidentally puts his feet on the water stop plate 2 or kicks the water stop plate 2, the water stop unit 1 is , Without being dropped from the guide block 30.

  In the water stop unit 1 mounted on the guide block 30 as described above, when water tries to enter the building H from outside to inside as shown by an arrow P in FIG. The water plate 2 receives a force in a direction orthogonal to the −Y side surface. The force indicated by the arrow a acts as a force that pushes the water blocking plate 2 supported at both ends by the guide block 30 in the direction indicated by the outlined arrow b. Therefore, the water stop plate 2 is pressed against the guide block 30 via the packing 4. The reaction force of the force indicated by the white arrow b acts as a force for pressing the water blocking plates 2 via the packing 5. Further, as shown in FIG. 5, when water tries to enter as shown by the arrow P, the water pressure of the water presses the lower end of the packing 5 constituting the recess 3a against the floor surface G. As a result, when the water is going to flood the building H, the watertightness of the packings 3, 4, and 5 increases as the water pressure of the flooding water increases.

  As described above, the water stop device 100 according to the present embodiment includes the pair of water stop plates 2 that are rotatably connected, and the pair of water stop plates 2 are opposite to the direction in which water is flooded. It is supported to protrude in the direction. Thereby, water can be stopped without providing a support at the center of the entrance F of the building H or the like. Therefore, it is possible to easily install the water stop device in the facility.

  In addition, even when the frontage of the entrance F is wide, water can be stopped using the two water stop plates 2. Therefore, it is not necessary to use a water stoppage plate which has high rigidity and is elongated according to the width. For this reason, the manufacturing cost of the water stoppage plate can be reduced.

  Further, the water stopping unit 1 according to the present embodiment includes two water stopping plates 2 that are connected so as to be able to swing up and down. Therefore, as shown in FIG. 4, the water stop unit 1 can be compactly folded and stored. Further, by folding the water stop unit 1, the portability of the water stop unit 1 is improved.

  In the water stop unit 1 according to the present embodiment, the two connected water stop plates 2 can be separated. Therefore, the portability of the water stopping unit 1 is improved by separating the water stopping plate 2.

  Further, the length of the water stop plate 2 can be standardized by adjusting each θ1 of the water stop plate 2 according to the frontage of the entrance F.

  Further, as shown in FIG. 4, when the water blocking plate 2 is folded, the packings 4 and 5 provided on each water blocking plate 2 overlap. For this reason, the packings 4 and 5 serve as cushioning materials, and can be transported without damaging the water blocking plate 2.

  Although the embodiment of the present invention has been described, the above embodiment has been presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in other various forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and their equivalents.
