FIG. 1 is a front view of a water stop plate according to an embodiment of the present invention. 2 and 3 are a rear view and a plan view of the water stop plate shown in FIG. 1, respectively, and FIG. 4 is an enlarged view of a part of the water stop plate shown in FIG. As shown in FIGS. 1 to 4, the water stop plate 1 of the present embodiment is arranged between the pair of side walls 91 and 92 of the structure via the first water stop members 3 and 3. Water can be stopped between the pair of side walls 91 and 92.

The water stop plate 1 is a rectangular flat plate-shaped plate body 2 arranged on the floor surface F in an upright state, a second water stop member 4 provided on the lower end surface of the plate body 2, and a back surface side of the plate body. It is provided with two holding members 10 and 20 provided on both the left and right sides, respectively.

The first water blocking members 3, 3 are band-shaped or plate-shaped members made of rubber, resin, or the like, and are interposed between the pair of side walls 91, 92 and both side end faces of the plate body 2 in the entire vertical direction. .. As shown in FIGS. 3 and 4, in the present embodiment, a first water blocking member 3 made of P-shaped watertight rubber is fixed to one side wall 91, and a strip plate is attached to one side end surface of the plate body 2. 6 is fixed, and the tubular portion of the first water blocking member 3 covers the strip 6 from the front (from the surface side of the plate body 2), so that one side wall 91 and the plate body 2 are separated from each other. It is sealed. A strip 7 is fixed to the other side wall 92, and a first water blocking member 3 made of P-shaped watertight rubber is fixed to the other side end surface of the plate body 2, and the first water stopping member 3 is fixed. By covering the strip 7 from the front with the tubular portion of the above, the space between the other side wall 92 and the plate body 2 is sealed.

The first water blocking member 3 interposed between the side walls 91, 92 and the plate body 2 may be fixed to either the side walls 91, 92 or the plate body 2, and the side walls 91, 92 and the plate body 2 may be fixed. It may be fixed to both sides. Alternatively, the first water blocking member 3 can be interposed at the time of construction without being fixed to the plate body 2. The first water blocking member 3 is not limited to the P-type watertight rubber, and may have another shape or material as long as it can be hermetically sealed.

For the plate body 2, for example, a honeycomb panel in which a core material having a honeycomb structure made of aluminum is coated with an aluminum plate can be used, and weight reduction can be achieved while maintaining rigidity. On the upper end surface of the plate body 2, rod-shaped grip portions 2a and 2a extending horizontally are provided in a portion cut out toward the back surface side.

The second water stop member 4 is a band-shaped or plate-shaped member made of rubber, resin, or the like like the first water stop member 3, and is arranged so as to partially project toward the surface side of the plate body 2. Therefore, it is provided over substantially the entire left-right direction of the plate body 2. A P-type watertight rubber can also be used for the second water-stopping member 4, and in this case, it is preferable to arrange the P-type watertight rubber so that the tubular portion protrudes.

The protruding portion of the second water blocking member 4 is covered with a third water stopping member 5 provided so as to hang down from the lower surface of the plate body 2. The third water blocking member 5 can also be formed in the shape of a band or a plate made of rubber, resin, or the like, similarly to the second water stopping member 4.

The holding members 10 and 20 include holding portion main bodies 11 and 21 formed in a hollow plate shape, and brackets 12 and 22 for fixing the holding portion main bodies 11 and 21 to the plate main body 2.

FIG. 5 is a cross-sectional view taken along the line AA of FIG. As shown in FIG. 5, the holding portion main body 11 of one holding member 10 is formed in a right-angled triangular shape in a side view so that the lower surface can contact the floor surface F to hold the plate main body 2 in an upright state. In addition, it has an appropriate thickness. The bracket 12 is integrated with the holding portion main body 11 and is formed in an L-shaped cross section so that the lower portion in contact with the floor surface F projects toward the back surface side of the plate main body 2, and the locking portion 13 is formed at the lower portion. It is formed. The other holding member 20 has the same configuration as the one holding member 10, and is arranged symmetrically with the one holding member 10. In the present embodiment, two holding members 10 and 20 are provided for the plate body 2, but the holding members may be single or three or more, and the length of the plate body 2 in the left-right direction and the like may be used. It is possible to provide an appropriate number according to the above.

As shown in FIG. 4, the locking portion 13 is formed of an elongated hole extending in the projecting direction of the bracket 12, and the opening width gradually widens from the base end portion 13a on the plate body 2 side toward the tip end portion 13b. It is formed. The protrusion 30 protruding from the floor surface F can be accommodated in the opening of the locking portion 13 so as to be relatively movable from the position indicated by the broken line.

Next, a method of stopping water between the pair of side walls 91 and 92 will be described using the water stop plate 1 having the above configuration. First, the protrusion 30 is installed in advance on the floor surface F on which the water stop plate 1 is installed. The configuration of the protrusion 30 is not particularly limited, but in the present embodiment, as shown in FIG. 6, the protrusion 30 having the head portion 30a formed of a countersunk bolt is used, and the inner peripheral surface thereof is used. A tubular body 31 having a threaded portion formed therein is embedded in the floor surface F, and a protrusion 30 is screwed into the tubular body 31. According to this configuration, in the normal state when the water stop plate 1 is not used, the head surface 30a of the protrusion 30 is shown by a two-dot chain line so as not to obstruct the passage of pedestrians and the like. It can be held in one state, and when the water stop plate 1 is used, the protrusion 30 can be rotated and pulled up so that the water stop plate 1 can be quickly and easily projected from the floor surface F.

The configuration for moving the protrusion 30 up and down may be such that the protrusion 30 can be held in the raised position, and other means such as fitting and meshing other than screwing the protrusion 30 and other members may be used. There may be. Further, the protrusion 30 may be fixed in a state of protruding from the floor surface F, and by appropriately covering the protrusion 30 with a floor mat or the like, it is possible to prevent a pedestrian from stumbling due to the protrusion 30.

Then, as shown in FIG. 7A, the water stop plate 1 is placed on the floor surface F so that the protrusion 30 is accommodated in the wide tip portion 13b of the locking portion 13. Then, as shown in FIG. 7B, by pressing the surface side of the plate body 2 in the direction indicated by the arrow, the protrusion 30 is relative to the base end portion 13a of the locking portion 13 as shown in FIG. It moves and the head 30a engages with the upper edge of the opening of the locking portion 13. In this way, the installation work of the water stop plate 1 is completed. The shape of the protrusion 30 is not particularly limited, but it is preferable that the upper portion can be bent into a hook shape so as to be engaged with the upper edge of the opening of the locking portion 13 as in the present embodiment, thereby stopping water. The plate 1 can be installed reliably.

According to the above water stopping method, as shown in FIG. 5, when water W stays on the surface side (outdoor side) of the water stopping plate 1 due to heavy rain or the like, the second water stopping member 5 is used to prevent the water W from staying. A pressing force P due to water pressure acts on the protruding portion of the water blocking member 4, and the second water stopping member 4 comes into close contact with the floor surface F. In the present invention, the third water stop member 5 is not indispensable, and the second water stop member 4 can be brought into close contact with the floor surface F even if the third water stop member 5 is not provided. Alternatively, the third water blocking member 5 can be integrated with the protruding portion of the second water stopping member 4.

When the plate body 2 receives water pressure on the surface, the holding member 10 is also pressed, so that the base end portion 13a of the locking portion 13 is locked to the protrusion 30 (the same applies to the holding member 20). As a result, the water stop plate 1 is securely fixed at a predetermined position on the floor surface F, so that the water stop by the second water stop member 4 can be well maintained for a long time.

The locking portion 13 with which the protrusion 30 is engaged is a long hole in the present embodiment, but there may be a notch or the like that can accommodate the protrusion 30 so as to be relatively movable. Further, the locking portion 13 is not necessarily limited to a configuration capable of accommodating the protruding portion 30, and the locking portion 13 protrudes when the surface side of the plate body 2 is pressed, for example, an overhanging piece projecting to the side of the holding member 10. Any configuration may be used as long as it can engage with the portion 30.

As described above, when the water stop plate 1 of the present embodiment receives water pressure on the surface side of the plate body 2, the second water stop member 4 prevents water from entering from below the plate body 2 and at the same time. The locking portions 13 and 23 are self-supportingly fixed by being locked to the protrusions 30 and 30. Therefore, not only can the water be stopped by a single water stop plate 1, but also a plurality of water stop plates 1 can be connected to stop the water. When a plurality of water stop plates 1 are used, the locking portions 13 and 23 are arranged so as to be locked to the protrusions 30 and 30 provided in advance corresponding to each, and the first water stop member 3 is provided. Can be connected via.

For example, in the water stopping method shown in FIG. 8, a plurality of water stopping plates 1 are arranged in a row between a pair of side walls 91 and 92 facing each other, and between the water stopping plates 1 and stopping. A first water blocking member 3 is interposed between the side walls 91 and 92 of the water plate 1. Since the water stop plate 1 is fixed independently by receiving water pressure in the direction indicated by the arrow, it is not necessary to provide an intermediate pillar or the like, and the installation work of the water stop plate 1 can be performed quickly and easily. Also in the water stopping method shown in FIG. 8, the fixing position of the first water stopping member 3 with respect to the plate body 2 is not particularly limited, but it is preferable that the first water stopping member 3 is fixed to only one of the end faces on both sides of the plate body 2. A plurality of first water blocking members 3 having the same configuration can be sequentially connected, and workability can be improved.

The pair of side walls 91, 92 do not necessarily have to be arranged so as to face each other. For example, with respect to the pair of side walls 91 and 92 shown in FIG. 9, water can be stopped between the pair of side walls 91 and 92 by connecting a plurality of water blocking plates 1 so as to bend at a right angle in the middle. .. In this water stopping method, the connecting bodies of the plurality of water stopping plates 1 are bent at right angles, and the side end faces of the other water stopping plates 1 are connected to the back surface of one water stopping plate 1 to stop these. Since the water pressure in the direction indicated by the arrow acts on the water plates 1 and 1, they are in close contact with each other, so that the water can be stopped reliably. In this configuration, one water stop plate 1 and the other water stop plate 1 do not necessarily have to be orthogonal to each other, and can be connected in an inclined state.
