Description

  TECHNICAL FIELD The present invention relates to a water blocking board for closing an opening of a building to block water from the outside and blocking water from entering the inside, and relates to a water blocking board which can be installed in the opening more simply and reliably.

  Recently, due to abnormal weather caused by global warming, record rapid guerrilla heavy rainfall frequently occurs in various places, and paving of roads is progressing in urban areas, and most of the rainwater that has rained Without infiltrating into the ground, the river rapidly flows from the sewerage facility to the river, and the river overflows in a short time, rainwater from the sewerage facility spouts out, and floods such as inundation under the floor and flooding on the floor occur.

  In the event of such flood damage, sandbags are conventionally stacked at building openings such as building entrances to form a water barrier to prevent water from entering the interior of buildings etc. However, sandbags are very heavy, so they are stacked The operation takes a lot of time and effort, it is difficult to prevent water damage that occurs in a short time, and it is bulky, so it is not easy to secure a storage place.

  Therefore, a dedicated water blocking board formed in accordance with the shape and size of the opening of the building such as the entrance may be used, and a more reliable water blocking method is being established. The water blocking plate is fixed to the opening to seal the opening and prevents the entry of water. For example, the water blocking plate is disposed in the opening and the inner side with respect to the frame constituting the opening A tension-type water stop plate is used that is tensioned and fixed in the horizontal direction.

  However, although the water blocking plate using such a fixing method can be fixed if the frame constituting the opening is provided substantially parallel to the front to the rear of the opening, the frame is not parallel. If it does not work in the horizontal direction, you can not do a secure fixing. In addition, even in the case where a concavo-convex having a certain height is formed on the frame that constitutes the opening, there are cases where reliable fixing can not be performed.

  On the other hand, according to Patent Document 1 (Japanese Patent Laid-Open No. 2016-204948), a hook is hooked on the rear side corner of the frame constituting the opening, and a water blocking plate disposed in front of the frame is connected to the hook On the other hand, there is disclosed a water immersion prevention device which fixes the water blocking plate to the opening by pulling the two in the front-rear direction. Thereby, even if the frame which comprises an opening is non-parallel, it is supposed that a water stop board can be fixed to the said opening.

JP, 2016-204948, A

  However, since the water immersion prevention device of Patent Document 1 includes the hook and the mechanical mechanism for pulling the hook as described above, the weight is increased together with the water blocking plate main body. For this reason, before fixing with the opening, it took time to move the water immersion prevention device in the vicinity of the opening, and the movement itself was also difficult. In addition, it is also difficult to ensure that there is no gap between the opening and the water blocking plate main body, and there is a problem that water intrudes from the derived gap to the building side.

  That is, focusing on the structure of the conventional water blocking plate, a mechanism for assisting the transport of the water blocking plate main body is not provided, and it is difficult to move the water blocking plate main body to the opening only with the strength of the installer. Yes, there is still room for improvement. Then, an object of this invention is to provide the water stop board provided with the mechanism which biases the water stop board main body which can arrange | position a water stop board main body to opening easily and reliably to an opening side.

In order to solve the above problems, the present invention is
A water blocking plate provided with a biasing mechanism that biases a water blocking plate for closing a building opening toward the opening side,
Water blocking plate body,
Floor contact part,
And an inclined plate whose angle of inclination can be changed with the floor contact portion as a fulcrum,
The floor surface contact portion is disposed on the bottom surface of one end region of the inclined plate, and the other end is slidably connected to the water stop plate in a substantially vertical direction,
Biasing the water blocking plate by further tilting the tilting angle of the tilting plate,
To provide a water blocking plate characterized by

  In the water blocking board of the present invention having such a configuration, the water blocking board main body can be biased toward the opening side of the building by, for example, the installer stepping on the inclined board and applying the treading force downward from above . More specifically, in a state in which the floor surface contact portion included in one end region of the inclined plate abuts on the floor surface, the other end region slides downward by the treading force, and the inclined plate moves to the floor It inclines to the surface side. As a result, the other end of the inclined plate exerts an urging force toward the opening side with the contact position of the floor surface abutting portion and the floor surface as a fulcrum, and the water blocking plate main body is biased and moved It can be done.

  The configuration of the present invention is preferably applicable to a type of water blocking board in which the installer carries the water blocking board and places the water blocking board on the floor surface of the opening to close the opening. In the water plate, a space may be generated between the water blocking plate and the opening side without the installer being aware. In particular, a gap is likely to be generated at the lower end side of the water blocking plate because the installer is hard to see, and installing the water blocking plate as it is may cause water leakage from between the water blocking plate and the opening (in particular, the lower side of the water blocking plate) There is. According to the configuration of the present invention, since the water blocking plate can be moved to the opening side by biasing, such a problem can be eliminated easily and surely. In addition, although it is intended to further improve water-repellency by using a backing material (seal material and packing) described later, it functions suitably also when there is a possibility that leakage to water may occur due to insufficient biasing to the opening side.

  Further, in the water blocking plate of the present invention described above, the water blocking plate main body is provided with at least one connection piece having a long hole extending from the water blocking plate surface and extending in a substantially vertical direction, Preferably, the other end area of the plate is slidably connected along said slot.

  In the water blocking plate of the present invention having such a configuration, the other end of the inclined plate is connected to the elongated hole provided in the connection piece, and if it is slidable along the shape of the elongated hole, the inclined plate is tilted. The operation can be stabilized, and the water blocking plate main body can be urged to the building opening side more reliably.

  Further, in the water blocking plate of the present invention, the inclined plate is connected to the water blocking plate main body by using a fixture, and the fixture is substantially perpendicular to the fixing surface and the fixing surface. The connection pieces disposed at both ends of the fixed surface, and both of the connection pieces have long holes extending substantially in the vertical direction, and the other end region of the inclined plate is along the long holes. It is desirable that it is connected slidably and the fixing surface is fixed to the water blocking plate main body.

  In the water blocking plate of the present invention having such a configuration, a mechanism for generating a biasing force can be used as a fixing member separate from the water blocking plate main body, which facilitates the manufacture of the device and makes two opposing The slide of the inclined plate can be made more stable by having the connection piece.

  Further, in the water blocking plate of the present invention described above, the inclined plate includes inclined holding means, and the inclined holding means pulls or lowers the other end region of the inclined plate upward. It is desirable that it is an elastic body that performs a push-up biasing to push up from the above.

  In the water blocking plate of the present invention having such a configuration, a treading force is applied by performing a pulling and biasing operation to lift the other end region of the tilting plate upward or a pressing force from below using the tilt holding means. The inclined state of the inclined plate at the time of not being maintained is maintained. Therefore, when the installer releases the depression force on the inclined plate, the inclined plate can be automatically returned to the original inclined state. Further, the other end region of the inclined plate is pulled upward, whereby one end region is oriented downward, and the floor surface contact portion can be reliably made to abut on the floor surface.

  Furthermore, after the treading force is added to the tilting plate to tilt it, and the water blocking plate main body is urged toward the opening side, one end region of the tilting plate is restored by the original tilting state return of the tilting plate by releasing the treading force. Move to the opening side. Therefore, the water blocking plate main body can be gradually moved to the opening side only by repeating application and release of the treading force to the inclined plate, and the opening can be closed easily and reliably.

  Further, in the water blocking plate of the present invention described above, it is preferable that the inclined plate can be rotated and locked with respect to the water blocking plate main body with the other end as an axis.

  In the water blocking plate of the present invention having such a configuration, the inclined plate is pivoted to the water blocking plate main body side about the other end (the connection portion with the connection piece) of the inclined plate as a shaft to connect the projection. The inclined plate can be erected substantially parallel to the water blocking plate main body by engaging with the engaging portion of the piece. As a result, when the water blocking plate is not in use, or after the installation in the opening is completed, it is possible to more easily store in the storage space while not using while preventing an accident such as a person accidentally putting a foot on the inclined plate. can do.

  Further, in the water blocking plate of the present invention described above, it is preferable that the floor surface contact portion is substantially hemispherical projecting downward.

  In the water blocking plate of the present invention having such a configuration, the floor surface contact portion is substantially hemispherical, and the arc arc side faces the floor surface, so that the contact area between the floor surface contact portion and the floor surface is It becomes smaller and can be a more stable fulcrum when the inclined plate is inclined. That is, even if the inclination angle of the inclined plate changes, any point of the substantially spherical floor surface contact portion comes into contact with the floor surface, and contacts with a small area with high surface pressure, without slipping It can be gripped securely and can function as a fulcrum.

  According to the present invention, it is possible to provide a water shut-off plate that includes a mechanism that biases the water shut-off plate main body toward the opening side, and allows the water shut-off plate main body to be easily and reliably disposed at the opening. Then, since the biasing mechanism is disposed on the lower end side of the water blocking plate, the lower end side that is likely to form a gap is reliably biased to fill the space between the water blocking plate and the opening to eliminate water leakage. it can.

  As shown in FIG. 6 (a) (the state before and after the application of the treading force is shown, the solid line indicates the state before the application, and the chain line indicates the state after the application). The other end region of the inclined plate 7 is pressed downward by the above-mentioned tread force in a state where the end region of is oriented toward the floor surface 59 and the lower surface of the floor contact portion 11 abuts on the floor surface 59 (In the present specification, the end in contact with the floor surface 59 and the area thereof are referred to as “one end” and “one end area”, respectively, and the opposite end and the area thereof Are respectively referred to as “the other end” and “the other end region”. At this time, the inclined plate 7 is inclined toward the floor surface 59 along the arc line L1 formed with the contact position between the floor surface contact portion 11 and the floor surface 59 as a fulcrum. Further, along with the inclination of the inclined plate 7, the penetration 13 slides downward along the long hole 37 of the fixing tool 9.

  As described above, the inclined plate 7 slides along the inclined line 37 and the long hole 37 along the arc line L1. At this time, since the floor contact portion 11 (fulcrum) of the inclined plate 7 strongly abuts on the floor 59 due to the treading force, it does not slip or shift, and the contact position is not changed. Thereby, the penetration 13 is biased rearward by a component force in the horizontal direction caused by the inclined movement of the penetration 13 along the arc line L1. That is, the fixing tool 9 and the water blocking plate main body 3 can be pressed to the opening 51 side through the penetration 13. More specifically, since the penetration 13 moves forward and downward along the arc line L1 and the long hole 37 along with the inclination, the horizontal distance L2 of the penetration 13 before and after the inclination is a biasing force. The water blocking plate main body 3 can be moved to the opening 51 side. At this time, along with the downward movement of the through 13, the elastic body 15 is extended, and the upward pulling force of the inclined plate 7 is further increased (see FIG. 6 (b)).

  Next, as shown in FIGS. 7A and 7B, the installer releases the treading force on the inclined plate 7 and pulls the inclined plate 7 upward by the elastic force (contraction force) of the elastic body 15. The floor contact portion 11 becomes capable of changing its position with the release of the treading force, and the floor contact portion 11 of the inclined plate 7 is on the side of the opening 51 by pulling the inclined plate 7 upward. As the contact position between the floor surface contact portion 11 and the floor surface 59 is changed, the fulcrum also moves to the opening 51 side.

  By repeating the application and release of the treading force described above a plurality of times, the water blocking plate 1 of the present embodiment can be gradually moved to the opening 51 side (the horizontal distance L2 can be moved by each application of the treading force). It is possible to make sure that the water blocking plate body 3 abuts on the opening edge portion 57. Even if the water blocking plate main body 3 has a weight which is difficult to move easily by the arm force, the installer can stop the water safely and easily by putting the weight on the inclined plate 7 as described above. It is possible to adjust the arrangement of the plate (depending on the mounting position of the water blocking plate 1, it is needless to say that the addition of one depression may be sufficient). If it does in this way, it goes without saying that the water blocking plate main body 3 and the opening edge portion 57 come in close contact and the water blocking property is improved, but if the abutment material 61A is provided on both end sides of the water blocking plate main body 3, The pad material 61A formed flexibly can be elastically crushed by the biasing force to further improve the water barrier property. Then, the installer repeatedly applies a certain degree of treading force, and this work may be stopped in a state in which movement is not possible (in a state where the inclined plate 7 is no longer inclined even if the stepping force is applied).

  After the arrangement adjustment of the water blocking plate 1 in the present embodiment is performed according to the above-described procedure, as shown in FIG. 9, the floor surface 59 is pressed using the pressing mechanism 63 provided in the water blocking plate main body 3. As this pressing mechanism 63, for example, a mechanism for pressing the water blocking plate 1 disclosed in JP-A-2017-160693 can be adopted. That is, when the operation lever is turned down, the fixed rotation shaft to which the rotation shaft core is fixed rotates, and the pressing portion abuts against the opening inner wall 65 in conjunction with the rotation of the shaft, and further falls the lever, As a result, the water blocking plate main body 3 can be pressed downward (floor surface 59 side) while the pressing portion abuts against the opening inner wall 65 and presses.

  After the water blocking plate main body 3 is brought into contact with the floor surface 59 and the opening edge portion 57 by moving the main water blocking plate 1 using the biasing device 5, the floor surface 59 is moved using the pressing mechanism 63. Press. In addition, when activating the pressing mechanism 63, the installer performs the operation in a state where the inclined plate 7 is depressed (in a state where a stepping force is applied), whereby the water blocking plate main body 3 is biased toward the opening 51 side. It is more preferable because it can be pressed and fixed to the floor surface 59. Thereby, the main water blocking plate 1 after the arrangement adjustment can be fixed more firmly, and the opening 51 can be sealed easily and reliably. In addition, FIG. 9 is a schematic diagram which shows the fixing method of the water stop plate 1 in this embodiment.

5. Storage of Inclined Plate 7 In the water blocking plate 1 of the present embodiment, the inclined plate 7 can be pivoted to the side of the fixture 9 when not in use. The method of storing the inclined plate 7 will be described in detail with reference to FIGS. 8 (a) and 8 (b). 8 (a) and 8 (b) are diagrams showing a method of storing the inclined plate 7, and FIG. 8 (a) is a schematic view showing a state in which the inclined plate 7 is rotated to the water blocking plate main body 3 side. FIG. 8B is a schematic view showing a state in which the projection 27 is engaged with the engagement portion 35.

  Storage of the inclined plate 7 can be achieved by rotating the inclined plate 7 to the water blocking plate main body 3 side as shown in FIGS. 8 (a) and 8 (b). More specifically, with respect to the storage method, turning is performed such that one end region of the inclined plate 7 is flipped up toward the water blocking plate main body 3 with the penetration 13 as a fulcrum (one end region of the inclined plate 7 It is rotated to move upward, and the projection 27 is engaged with and engaged with the engaging portion 35 of the fixing tool 9. That is, the water blocking plate 1 of the present embodiment has a configuration in which the inclined plate 7 can be pivoted and locked with respect to the water blocking plate main body 3 with the other end as the axis. .

  As described above, since the inclined plate 7 is pulled upward by the elastic body 15 through the penetration 13, the projection 27 is pulled upward, and the engagement between the engaging portion 35 and the projection 27 is achieved. Is maintained. By the said state, the inclination board 7 stands upright substantially parallel to the water stop board main body 3, and it will be in a storing state. In this way, by placing the inclined plate 7 in the stored state, when the water blocking plate 1 of this embodiment is not used or after the installation to the opening 51 is completed, a person erroneously hooks the inclined plate 7 etc. Can be stored in the storage space more easily when not in use while preventing an accident.
