Description

Technical Field

[0001] The present invention relates to a water stop plate that prevents water from entering openings in buildings and underpasses during water level rise.

Background Art

[0002] Conventionally, when water level rises due to typhoons or heavy rainstorms and enters openings in buildings and underpasses, there is a risk of significant damage caused by flooding. Therefore, in preparation for such a situation, grooved columns are erected opposite each other on both sides of the openings of buildings and underpasses in advance, and a water stop plate is stored near these columns. When water level rise occurs, the water stop plate is inserted into the groove of the column to close the opening and prevent water from entering. This has been conventionally known (see Patent Document 1). By the way, while the above-mentioned water stop plate can prevent the intrusion of rising water as described above, it acts as an obstacle to pedestrians and the like trying to pass through the opening. Therefore, in order to solve such a problem, for example, in the invention described in Patent Document 2, an auxiliary waterproof panel is fitted into the opening of a waterproof door through a sealing member, and this auxiliary waterproof panel is pushed in the door thickness direction by a number of pressure contact handles and pressed against the sealing member.

[0008] Next, embodiments of the present invention will be described in detail with reference to the drawings.

[0009] <First Embodiment> Next, a specific embodiment having the above-described features will be explained in detail with reference to the drawings. The water-stopping device 1 comprises a water-stopping plate 10 that prevents water from flowing from one side to the other, and left and right water-stopping support parts 20, 20 that support the water-stopping plate 10 on both sides, and is installed on a stationary surface such as a floor so as to close off an opening in a building or the like. In the illustrated example, the one side and the other side are the outdoor side and the indoor side, respectively. Alternatively, one side may be the indoor side and the other side the outdoor side.

[0010] The water-stopping plate 10 comprises a main water-stopping plate 11 having a notch 11a on its upper end, an auxiliary water-stopping plate 12 that fits detachably into the notch 11a, and watertight materials 31, 32, and 33 that are compressed by being sandwiched between the inner surface 11a1 of the notch 11a and the end of the auxiliary water-stopping plate 12 facing the inner surface 11a1.

[0011] The main water-stopping plate 11 is formed in the shape of a horizontally elongated rectangular plate, and has a notch 11a on its upper side that penetrates in the thickness direction and is concave when viewed from the front. The upper end of the main water-stopping plate 11 is provided with a handle portion 11b that can be gripped by hand. In other words, the main water-stopping plate 11 is normally stored in a designated storage place, and when the water level rises, it is transported by gripping the handle portion 11b and set between the left and right water-stopping support portions 20.

[0012] The notch 11a has an inner surface 11a1 that is concave when viewed from the outside, and a protruding piece 11a2 that extends from the indoor side of the inner surface 11a1 (see Figure 4).

[0013] Furthermore, a watertight material (not shown) made of an elastic material is provided between the main watertight plate 11 and the left and right watertight support parts 20, and between the lower end of the main watertight plate 11 and the lower immovable surface. The main watertight plate 11 is detachably attached to the left and right watertight support parts 20 via a locking mechanism (not shown).

[0014] Each water-stopping support section 20 is a columnar member that is elongated in the vertical direction and is fixed to an opening or floor surface of a building or the like where the water-stopping device 1 is to be installed.

[0015] Further, the auxiliary water stop plate 12 has a substantially rectangular plate shape and is inserted from the upper side into the notch 11a of the main body water stop plate 11 via watertight materials 31, 32, and 33 described later. A hand-held portion 11b for the insertion operation is provided at the upper end portion of the auxiliary water stop plate 12.

[0016] The left and right ends of the auxiliary water stop plate 12 are formed in a substantially trapezoidal cross-section shape that gradually thins towards the side. In other words, inclined surfaces 12a are formed on the front and back surfaces of the auxiliary water stop plate 12 at its left and right ends so that the thickness decreases towards the end sides.

[0017] The left end side of the auxiliary water stop plate 12 fits and is press-fitted into the watertight material 31, and the right end side of the auxiliary water stop plate 12 fits and is press-fitted into the watertight material 32. Also, the lower end of the auxiliary water stop plate 12 is press-fitted into the watertight material 33.

[0018] The watertight materials 31, 32, and 33 are each formed from an elastic material such as rubber or elastomer resin.

[0019] These watertight materials 31, 32, and 33 are fixed to the inner surface 11a1 of the notch 11a in the main body water stop plate 11. Specifically, the watertight material 31 is overlapped and adhered to the left side portion of the inner surface 11a1 of the notch 11a, and its indoor-side end is in contact with the protruding piece portion 11a2 (see FIG. 4). The watertight material 32 is overlapped and adhered to the right side portion of the inner surface 11a1 of the notch 11a, and its indoor-side end is in contact with the protruding piece portion 11a2. The watertight material 33 is overlapped and adhered to the lower side portion of the inner surface 11a1 of the notch 11a, and its indoor-side end is in contact with the protruding piece portion 11a2.

[0020] The watertight material 31 has a concave cross-section that fits into the end in the width direction of the auxiliary water stop plate 12 and is continuous in the vertical direction along the inner surface 11a1 of the notch 11a. More specifically, the watertight material 31 is formed in a concave cross-section, having a base piece 31a that overlaps the inner surface 11a1 of the notch 11a, a first projection 31b protruding from the outdoor end of the base piece 31a, and a second projection 31c protruding from the indoor end of the base piece 31a (see Figures 3 and 4).

[0021] The first projection 31b and the second projection 31c are inclined inward in the thickness direction of the auxiliary water-stopping plate 12, so that they approach the surface of the auxiliary water-stopping plate 12 (more specifically, the inclined surface 12a) as they move towards the tip (see Figure 3).

[0022] The first projection 31b is exposed to the outside on the outdoor side (see Figures 1 and 2) and functions as a surface that receives water pressure during floods. That is, when the first projection 31b receives water pressure from the back side, it bends inward and is pressed against the auxiliary water-stopping plate 12, improving watertightness.

[0023] Furthermore, when the auxiliary water-stopping plate 12 is pushed inward by water pressure, the second projection 31c is sandwiched and pressed between the auxiliary water-stopping plate 12 and the projection 11a2 of the notch 11a, thereby improving watertightness.

[0024] The watertight material 32 has a shape symmetrical to the watertight material 31 and, like the watertight material 31, has a base portion 32a, a first projection portion 32b, and a second projection portion 32c.

[0025] The watertight material 33 is formed in the shape of a rectangular flat plate that is in contact with the inner surface 11a1 on the bottom side of the notch 11a. As another example, this watertight material 33 can also be formed with a concave cross-section, similar to the watertight materials 31 and 32.

[0026] Next, the characteristic effects of the water-stopping device 1 with the above configuration will be explained in detail. As shown in Figure 1, with the auxiliary water stopper 12 removed, it is possible to prevent water from entering to a depth of H1 between the main water stopper 11 and the watertight material 33. In this state, a person can easily step over the notched portion 11a.

[0027] If the depth of the rising water is expected to exceed dimension H1, the auxiliary water stopper plate 12 can be fitted into the notch 11a of the main water stopper plate 11 to prevent water from entering up to a depth of dimension H2. In this case, the fitted auxiliary water-stopping plate 12 presses its lower end against the watertight material 33, and its left and right ends are fitted watertightly to the watertight materials 31 and 32, respectively. Therefore, the gap between the main water-stopping plate 11 and the auxiliary water-stopping plate 12 is eliminated, thereby preventing water from entering the indoor side.

[0028] <Second Embodiment> The water-stopping device 2 shown in Figure 5 is constructed by replacing the auxiliary water-stopping plate 12 with an auxiliary water-stopping plate 13 in the water-stopping device 1 described above. The auxiliary water-stopping plate 13 is formed in the shape of a rectangular plate and fits into the notch 11a via a watertight material (not shown). One end of the auxiliary water-stopping plate 13 is pivotally supported by a hinge 14 at the lower end of the notch 11a on the outdoor side surface of the main water-stopping plate 11. The auxiliary water-stopping plate 13 can rotate between a position where it is fitted into the notch 11a and a position where it has rotated outwards from the notch 11a (see Figure 5), using the hinge 14 as a pivot point.

[0029] Therefore, according to the water-stopping device 2 shown in Figure 5, when the auxiliary water-stopping plate 13 is rotated to the outdoor side, it is possible to prevent water from entering to a depth of height H1, and a person can easily step over the notch 11a. Also, when the auxiliary water-stopping plate 13 is fitted into the notch 11a, it is possible to prevent water from entering to a depth of height H2.

[0030] <Variation> In the above embodiment, the watertight materials 31, 32, and 33 are each made as separate components, but these watertight materials can be made as a single, concave component when viewed from the front.

[0031] Furthermore, in the above embodiment, a single notch 11a on the central side of the main water-stopping plate 11 is closed by the auxiliary water-stopping plate 12. However, other examples include providing a notch on the end side in the width direction of the main water-stopping plate 11 and closing this notch with the auxiliary water-stopping plate, or providing multiple notches in the width direction of the main water-stopping plate 11 and closing each of these notches with the auxiliary water-stopping plate.

[0032] Furthermore, in the above embodiment, watertight materials 31, 32, and 33 are provided only on the notched portion 11a side. However, other examples include a configuration in which watertight materials are provided only on the auxiliary watertight plate 12 side of the notched portion 11a and the auxiliary watertight plate 12, or a configuration in which watertight materials are provided on both the notched portion 11a and the auxiliary watertight plate 12.

[0033] Furthermore, while the above-described water-stopping device 1 allows the auxiliary water-stopping plate 12 to be inserted into and removed from the notch 11a from above, another example would be a configuration in which the auxiliary water-stopping plate 12 can be fitted into and removed from the notch 11a from the outdoor or indoor side.

[0034] Furthermore, in the above-described water-stopping device 2, the auxiliary water-stopping plate 13 is rotated using the horizontal rotation axis (hinge 14) as a pivot point to fit into and out of the notch 11a. However, in another example, it is also possible to rotate the auxiliary water-stopping plate 13 using the vertical rotation axis as a pivot point to fit into and out of the notch 11a.

[0035] Furthermore, the present invention is not limited to the specific configurations described above, and can be modified as appropriate without altering the essence of the invention.

(1) A water-stopping plate that prevents water from flowing from one side to the other, comprising a main water-stopping plate having a notch at its upper end, an auxiliary water-stopping plate that fits detachably into the notch, and a watertight material that is compressed between the inner surface of the notch and the end of the auxiliary water-stopping plate facing the inner surface (see Figure 1).
