Moreover, FIG. 2 is a top view which shows the installation state of the water stop board.

  In this embodiment, an example will be described in which the water stop plate 1 is attached by inserting both ends 1a of the water stop plate 1 into a pair of vertical grooves 10 formed of shutter door grooves as shown in FIG.

  As shown in FIG. 1, the water stop plate 1 has a rectangular shape in which a pair of flexible support plates 3 and 4 are provided on both sides with a water stop rubber plate 2 in between. ), The width dimension (horizontal dimension) is longer than the height dimension (vertical dimension). And the both ends 1a of the width direction of the water stop board 1 are inserted in each vertical groove 10, and it attaches between a pair of vertical grooves 10. FIG. The width dimension of the water stop plate 1 is set to be longer than the dimension between the pair of vertical grooves 10, and the water stop plate 1 is bent between the pair of vertical grooves 10 (see FIG. 2). )become.

  The rubber plate 2 has a rectangular shape with a thickness of about 10 mm to 12 mm, for example, and the support plates 3 and 4 have a rectangular shape with a thickness of about 1 mm made of, for example, stainless steel, aluminum, steel, or resin. Is used. Both of the support plates 3 and 4 have the same width dimension (horizontal dimension) and height dimension (vertical dimension), and the width dimension of the support plates 3 and 4 is shorter than the width dimension of the rubber plate 2. The height dimensions of the plates 3 and 4 are set shorter than the height dimension of the rubber plate 2. The material of the support plates 3 and 4 may be the same or different.

  One of the support plates 3 and 4, in the illustrated example, the support plate 3 is bonded to the rubber plate 2, and the other support plate 4 is attached to the rubber plate 2 via bolts 5 a and nuts 5 b. Specifically, for example, three bolts 5a and three nuts 5b in the width direction of the water blocking plate 1 and three in the height direction are provided, for example, a total of nine support plates 3 sandwiching the rubber plate 2, 4 is sandwiched between the head 5c of the bolt 5a and the nut 5b, so that the separation distance between the support plates 3 and 4 is maintained substantially constant. And in the state hold | maintained in this way, the circumference | surroundings of the rubber plate 2 protrude outside the outer edge of the support plates 3 and 4 in four directions, The length of the protrusion part 2a is about 3 mm-5 mm, for example It has become. The rubber plate 2 is provided with a circular through hole 2b through which the bolt 5a passes. The diameter of the through hole 2b is set to be approximately the same as or shorter than the diameter of the bolt 5a, It can be done. The support plate 3 is provided with a circular through hole 3a having the same diameter as that of the bolt 5a.

  In addition, a round hole 4a through which the bolt 5a is passed is provided in the center portion in the width direction of the other support plate 4, and the left and right sides of the support plate 4 are bent so that the width direction of the water stop plate 1 is curved. A long hole 4b that allows movement of the bolt 5a is provided. The long hole 4 b is long in the width direction of the water blocking plate 1. This long hole 4b allows the position of the bolt 5a to change as the water stop plate 1 is bent.

  The water stop plate 1 configured in this manner is bent so that the width direction of the water stop plate 1 is curved so that the length between both ends 1a is shorter than the distance between the pair of vertical grooves 10, and that state It is attached by inserting both ends 1a into each longitudinal groove 10 in. In this attached state, as described above, since the width dimension of the water stop plate 1 is set longer than the dimension between the pair of vertical grooves 10, the water stop plate 1 is curved between the pair of vertical grooves 10. A bent mounting state is obtained. At this time, the water stop plate 1 is curved so as to protrude outward in the direction of receiving the water pressure. In addition, as the protrusion length, it is preferable to make it within about 100 mm, for example with the water stop board whose width dimension is 1800 mm. However, it may be curved and protrude outward, either on the support plate 3 side or on the support plate 4 side, and the elongated hole 4b allows the bolt 5a to move regardless of which side is selected.

  Since the water stop plate 1 is bent and attached between the pair of longitudinal grooves 10 as described above so as to protrude toward the side receiving the water pressure, the water pressure received by the water stop plate 1 is applied to both ends 1a of the water stop plate 1. Can be received while pressing the groove bottom 11 of the longitudinal groove 10. Thereby, the water pressure receiving force in the water stop plate 1 itself can be reduced.

In addition, since the rubber plate 2 has the protruding portion 2a described above, the protruding portion 2a presses the periphery of the groove bottom 11 as shown in FIG. 3, and this also provides excellent water tightness.

  Furthermore, since the water stop plate 1 adopts a sandwich structure in which water is stopped by the rubber plate 2 between the pair of support plates 3 and 4, the water stop plate is constituted only by the same material as the support plates 3 and 4. Further, the weight can be reduced by the presence of the rubber plate 2. Further, when the water stop plate 1 is not used, the water stop plate 1 is changed from a curved shape to a flat shape, so that there is an advantage that it can be easily stored in advance using a gap near the shutter.

  In addition, since the rubber plate 2 protrudes outward from the both support plates 3 and 4 in the four directions of the water stop plate 1, the water stop plate has one direction (lower side) intersecting the direction of both ends 1a facing downward. Is attached to the pair of vertical grooves 10 and the water stop portion, that is, the floor surface (including the ground etc.) of the portion where the shutter is provided, and protrudes outward from the support plates 3 and 4 of the rubber plate 2. Since the part 2a contacts, it is excellent in watertightness. In this embodiment, the projecting portions 2a are provided in the four directions of the water stop plate 2. However, by determining in advance the direction of the lower side, the projecting portions in the three directions of the lower side and both ends 1a are provided. 2a may be provided. Conversely, when the protrusions 2a are provided in four directions, they can be used regardless of the vertical direction.

  Although not explicitly stated in the above-described embodiment, the rubber plate having the same quality is used throughout, but the present invention is not limited to this. For example, by changing the material between the upper part and the lower part of the rubber plate 2 and using soft rubber for the part used as the lower part, the soft rubber is applied to the floor surface (including the ground) of the water stop part. The watertightness can be ensured regardless of some unevenness.

  Moreover, although the case where a water stop board is attached using the door groove | channel of a shutter is mentioned as an example in embodiment mentioned above, this invention is not limited to this. For example, as shown in FIG. 4, in a location where no shutter is provided, a groove steel 21 is provided in the longitudinal direction on each of the side wall surfaces 20 facing the entrance and exit, and a longitudinal groove 21 a made up of a groove in the groove steel 21. By inserting the end 1a of the water stop plate 1 into the water stop plate 1, the water stop plate 1 can be attached.
