  In the water shielding apparatus described in Patent Document 1, since a total of four water stop plate pressing tools are used, the work for mounting the water stop plate on the opening is troublesome and the workability is not good.

  This invention is made | formed in order to cope with the said problem, and it aims at providing the water shielding apparatus which can improve workability | operativity.

  In order to achieve the above object, a feature of the present invention is a water shielding device for blocking the flow of water that attempts to flow from an outside to an inside provided in a building, and is attached to and detached from the opening. A water-impervious plate that can be provided and blocks the flow of water, and is provided at a horizontal end of the opening so as to face the horizontal end of the water-impervious plate from the inside. A supporting portion that supports the water plate from the inside and a horizontal end portion of the opening so as to face the horizontal end portion of the water shielding plate from above, and the water shielding plate moves upward. And a first water blocking member provided between the water shielding plate and the bottom of the opening, and an inner portion directed toward the inner side of the water shielding plate. The angle formed between the side surface and the upper surface of the bottom of the opening is that it is smaller than 90 degrees.

  In this configuration, when the water pressure acts on the water shielding plate from the outside, the water shielding plate is pressed against the support portion and fixed. Therefore, the structure for fixing a water shielding board can be simplified and workability can be improved.

  Since the angle formed by the inner surface of the water shielding plate and the upper surface of the bottom of the opening is smaller than 90 degrees, when the lower end of the water shielding plate is pushed inward by water pressure, the angle increases and the shielding is performed. The upper end portion of the water plate is pressed against the first movement blocking portion. Thereby, a 1st water stop member is compressed between a water shielding board and the bottom part of an opening part, and the penetration | invasion of the water from these is prevented.

  Another feature of the present invention is that the upper surface of the bottom portion of the opening is formed horizontally, and the water shielding plate is disposed so as to be inclined such that the upper end portion is located on the inner side of the lower end portion. There is in being.

  In this configuration, the water shielding plate can be pressed against the support portion by the gravity acting on the water shielding plate, and the stability of the water shielding plate can be enhanced. In addition, the 2nd water stop member may be arrange | positioned between the water shielding board and the support part.

It is in having 1 contact surface and the 2nd contact surface which a said 1st water stop member contacts when the said water shielding board receives the water pressure and curves.

  When the water shielding plate receives water pressure from the upstream side, the water shielding plate is deformed so that the horizontal center portion swells inward, and the first water stop member is pressed against the second contact surface and compressed. This prevents water from entering between the water shielding plate and the bottom of the opening.

  Another feature of the present invention is that the water shielding plate is formed of fiber reinforced plastic.

  In this configuration, since the water shielding plate is formed of fiber reinforced plastic, the weight of the water shielding plate can be greatly reduced as compared with the case where the water shielding plate is formed of metal such as stainless steel.

  Another feature of the present invention is that it is provided at the horizontal end of the opening so as to face the lower end of the horizontal end of the water shielding plate from the outside, and the water shielding plate extends outward. The object of the present invention is to provide a second movement blocking unit for blocking the movement.

  In this configuration, when the water shielding plate is attached to the opening, the lower end portion of the horizontal end portion of the water shielding plate can be positioned between the support portion and the second movement blocking portion. Therefore, after that, it is only necessary to press the water shielding plate against the support portion, and the water shielding plate can be easily arranged at an appropriate position of the opening.

  Another feature of the present invention is that the water shielding plate includes a plate-shaped main body portion and a contact portion that is provided at a lower end portion of the main body portion and contacts the second movement blocking portion from the inside. The first water stop member is provided on the inner portion of the lower end portion of the main body portion with respect to the abutting portion, and includes a virtual surface including a surface facing the outer side of the main body portion. Assuming that the abutting surface directed to the outside of the abutting portion is disposed on the inside of the virtual surface.

  When mounting the water shielding plate on the opening, first, the lower end of the horizontal end of the water shielding plate is inserted between the support portion and the second movement blocking portion. Subsequently, the entire water shielding plate is rotated inward about the contact point between the contact portion and the second movement blocking portion, and the water shielding plate is pressed against the support portion. At this time, the first water stop member is rotated while being pressed against the bottom of the opening, but the first water stop member has a small turning radius and a short moving distance. Hard to damage.

  Another feature of the present invention includes a base portion provided with the support portion and the first movement prevention portion, and the base portion is fixed to a horizontal end portion of the opening portion using a fixing means. There is.

  In this configuration, it is possible to reduce the number of parts and reduce the manufacturing cost and the construction cost.

  Another feature of the present invention is provided so as to be movable between a lock position opposed to the horizontal end of the water shielding plate from the outside and an unlock position deviated from the lock position. It is in providing the locking means which has a locking member.

  Since the water shielding plate is detachably attached to the outdoor opening, the water shielding plate may be damaged by theft. In the above configuration, since the water shielding plate cannot be detached from the opening when the lock member is disposed at the lock position, the water shielding plate can be prevented from being stolen by fixing the lock member at the lock position. As a fixing means for fixing the lock member to the lock position, a commercially available padlock can be appropriately selected and used.

  Another feature of the present invention is that the locking means has a holding member for holding the lock member at the unlocked position.

  In this configuration, when the water shielding plate is attached to and detached from the opening, the lock member can be retracted to the unlock position by the holding member. Therefore, even one person can easily perform the attaching / detaching work of the water shielding plate.

The thickness of the interference preventing member 32 is made thicker than the protruding length (length in the left-right direction) of the bolt 38 protruding from the one surface 24a of the base 24. Accordingly, the bolt 38 does not protrude from the storage space S to the outside.

  Below, the usage method of the water shielding apparatus 10 shown in FIG. 1 and FIG. 2 is demonstrated. As shown in FIG. 2, in the normal state, the opening 16 is used for traffic, so the water shielding plate 12 is not attached to the opening 16. When heavy rain, flooding, tsunami, or the like occurs, it is necessary to prevent water flowing on the ground surface G from entering the inside of the building 14 through the opening 16. Therefore, the worker attaches the water shielding plate 12 to the opening 16.

  As shown by a two-dot chain line in FIG. 3, when the water shielding plate 12 is attached to the opening portion 16, the lower end portion 12 b of the water shielding plate 12 is interposed between the support portion 26 and the second movement blocking portion 30. The lower end 12b is positioned between them. Thereafter, as shown by a solid line in FIG. 3, the entire water shielding plate 12 is rotated inward about the contact point K between the lower end portion 12 b of the water shielding plate 12 and the second movement blocking portion 30, The plate 12 is pressed against the support portion 26 via the second water stop member 22. Since there is nothing in the passage R that obstructs the mounting of the water shielding plate 12, the mounting operation of the water shielding plate 12 can be easily performed with one touch.

As shown in FIG. 3, in a state where the water shielding plate 12 is attached to the opening 16, when the water W flowing on the ground surface G increases, the water pressure of the water W acts on the lower end portion 12 b of the water shielding plate 12. The lower end 12b is moved inward. As shown in FIG. 2, the bottom 16 a of the opening 16 includes a first contact surface Q <b> 1 with which the first water blocking member 20 (FIG. 4) contacts when the water shielding plate 12 is not subjected to water pressure, When the plate 12 receives water pressure and curves inward (see the two-dot chain line in FIG. 1), it has a second contact surface Q2 with which the first water stop member 20 (FIG. 4) contacts. The first contact surface Q1 and the second contact surface Q2 are formed continuously in the horizontal direction. Therefore, in the process in which the first water stop member 20 (FIG. 4) moves from the first contact surface Q1 to the second contact surface Q2, the first water stop member 20 (FIG. 4) is placed on the bottom 16a of the opening 16. It is possible to prevent the water from entering due to the floating of the first water stop member 20 (FIG. 4).

  As shown by a two-dot chain line in FIG. 1, when the lower end portion 12b of the water shielding plate 12 is bent so as to bulge inward due to water pressure, the inclination angle of the water shielding plate 12 approaches 90 degrees. The upper end portion 12 a of the plate 12 is moved upward and is brought into contact with the first movement blocking portion 28. Then, the upward movement of the upper end portion 12a of the water shielding plate 12 is blocked, and the movement of the water shielding plate 12 to the inside of the lower end portion 12b is blocked. Thereby, since the 1st water stop member 20 (FIG. 4) is compressed greatly, the permeation of the water from between the water shielding board 12 and the bottom part 16a of the opening part 16 can be prevented.

(Effect of 1st Embodiment)
According to the present embodiment, the following effects can be achieved by the above configuration. That is, as shown in FIG. 3, when the water pressure acts on the water shielding plate 12 from the outside, the water shielding plate 12 is pressed against the support portion 26 via the second water stop member 22. Therefore, the structure for fixing the water shielding plate 12 can be simplified, and workability can be improved. Moreover, since the movement to the upper side of the upper end part 12a of the water shielding board 12 can be blocked | prevented by the 1st movement prevention part 28, the movement to the inner side of the lower end part 12b of the water shielding board 12 can also be blocked | prevented. Thereby, the 1st water stop member 20 can be compressed greatly between the water shielding board 12 and the bottom part 16a of the opening part 16, and it can prevent that water permeates from between these.

  As shown by a two-dot chain line in FIG. 3, when installing the water shielding plate 12, the lower end portion 12 b of the horizontal end portion 12 e (FIG. 1) of the water shielding plate 12 is connected to the support portion 26 and the second movement prevention After that, it is only necessary to press the water shielding plate 12 against the support portion 26 via the second water blocking member 22, and the water shielding plate 12 is positioned at the appropriate position of the opening 16. It can be easily installed.

  As shown in FIG. 6, since the support part 26, the 1st movement prevention part 28, and the 2nd movement prevention part 30 are integrally provided with respect to the plate-shaped base 24, it manufactures by reducing a number of parts. Costs and construction costs can be reduced.

  As shown in FIG. 5, since the interference preventing member 32 is provided on the one surface 24a of the base 24, the bolt 38 (FIG. 6) as the “fixing means” and the water shielding plate 12 (FIG. 3) are provided. Interference can be prevented.

  In carrying out the present invention, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the object of the present invention. For example, as shown in FIG. 6, in the above embodiment, the storage space S in which the bolt 38 as the “fixing means” is arranged is configured by the hole 64 and the notch 66, but the storage space S is an interference prevention member. It may be configured by a recess (not shown) provided in 32.

The attachment member 70 has a plate-like first portion 70a and a plate-like second portion 70b that are joined so that the shape when viewed from above is T-shaped. A plurality of (two in this embodiment) through-holes 78 into which the first bolts 74 are inserted are formed in the first portion 70a, and a plurality of through-holes 78 are inserted into the second portion 70b. (Three in this embodiment) through-holes 80 are formed.

  When the base 24 is directly attached to the horizontal end 16b of the opening 16, the attachment position is limited. However, in the configuration shown in FIG. 7, the attachment is performed via the attachment member 70. Can be changed.

  FIG. 8 is a perspective view showing a state in which the lock member 82 is attached to the support portion 26. As shown in FIG. 8, the water-impervious device 10 moves between a lock position P1 that faces the horizontal end 12e of the water-impervious plate 12 from the outside and an unlock position P2 that is out of the lock position P1. A lock member 82 provided as possible may be provided. The lock member 82 is an L-shaped member when viewed from the right side, and includes a plate-like first portion 82a and a plate-like second portion 82b. An attachment plate portion 86 is provided at an end portion of the first portion 82 a via a hinge portion 84, and the attachment plate portion 86 is joined to the upper end portion of the support portion 26.
