Description

[Technical field]

[0001] The present invention relates to a water stop device that can be installed at entrances to buildings such as houses and apartment buildings, and at gates to external structures around the premises. [Background technology]

[0002] 2. Description of the Related Art Water-stopping members have conventionally been used to prevent water from entering buildings such as houses, condominiums, and offices due to localized submersion caused by river floods or heavy rain, and to prevent water from entering through entrances to subways and underground passages.

[0003] There are various types of waterproofing materials, including traditional sandbags, which are bags filled with soil, as well as waterproof plates and sheets.

[0004] For example, Patent Document 1 discloses a waterproof board in which divided panel materials are stacked one above the other and connected to each other to form a desired height, in which a protrusion is formed on the front end of the top surface of the lower panel material, and a groove that fits into the protrusion is formed on the front end of the bottom surface of the upper panel material, and the upper panel material is fitted into the lower panel material, and an engaging piece on the rear surface of the upper panel material engages with a locking piece on the rear surface of the lower panel material to connect and fix the upper and lower panel materials.

[0005] [Patent Document 1] JP 2005-2644 A Summary of the Invention [Problem to be solved by the invention]

[0006] The waterproof board allows the panels to be directly connected to each other, reducing the number of parts and making assembly easy and quick. However, since it is necessary to disassemble the waterproof board in normal times to secure a place to store the panels, there is a risk that the protrusions, locking pieces, engagement pieces, etc. at the connection points between the panels may be deformed or damaged during storage, storage, and assembly of the waterproof board, which may cause problems in connecting the panels to each other. In addition, it is necessary to maintain watertightness between the bottom end of the panel material and the floor surface, and in the case of a floor surface having a groove for storing the bottom end of the panel, if the waterproof board is not used, the groove must be blocked, which may increase the number of parts other than the waterproof board.

[0007] To provide a water stop device which solves the above-mentioned problems, easily ensures a watertight state between the water stop device and the installation surface even if there is no groove or the like on the installation surface, and can be used as a bench or deck when not in use as a water stop device. [Means for solving the problem]

[0008] In order to achieve the above object, the present invention has the following configuration. That is, the water stop device according to the present invention is a water stop device that can be placed in front of an entrance of an installation object, and is provided with a water stop plate portion that is placed across the width of the entrance, an elastic sheet material attached to the lower part of the water stop plate portion, a base portion that is fixed to the rear side of the water stop plate portion, and foldable legs that are attached to the base portion, The water stop portion includes a vertical plate portion arranged in a vertical plate shape, The legs are placed upright on the installation surface in the open state. Water stop plate The present invention is characterized in that the vertical plate portion is capable of being installed with its outer surface facing upward.

[0009] In the present invention, the water stop plate portion comprises a vertical plate portion facing the entrance / exit, a horizontal plate portion formed from the lower end of the vertical plate portion toward the front, and a lower plate portion formed downward from the tip of the horizontal plate portion, and at least a part of the elastic sheet material may be arranged at the lower end of the lower plate portion. Effect of the Invention

[0010] In the water stop device of the present invention, when the water level outside the installed object rises due to flooding or the like, water pressure presses from the water stop plate portion through the elastic sheet material to the installation surface, making it difficult for water to seep in between the water stop plate portion and the installation surface.In addition, under normal circumstances, if the legs are opened, the water stop plate portion can be used as a veranda or deck with the seating area.

[0011] In the present invention, the water stop plate portion comprises a vertical plate portion facing the entrance / exit, a horizontal plate portion formed from the lower end of the vertical plate portion toward the front, and a lower plate portion formed from the tip of the horizontal plate portion toward a downward direction, and at least a part of the elastic sheet material is arranged at the lower end of the lower plate portion.When water enters the structure, a load is applied to the elastic sheet material from the horizontal plate portion through the lower plate portion due to water pressure, which acts biased toward the front side of the elastic sheet material, making it even more difficult for water to penetrate between the elastic sheet material and the installation surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

[0014] In the drawings, reference numeral 10 denotes a waterstop portion, 20 denotes a base portion fixed to the installed object relative to the waterstop portion 10, 30 denotes legs attached to the base portion 20 in a foldable manner, and 40 denotes a pair of side panels arranged on both sides of the waterstop portion 10. The waterstop device 100 of the present invention comprises a waterstop portion 10, a base portion 20, legs 30 and side panels 40, and is placed at the entrance or exit of the installed object to prevent water from entering the installed object when there is a risk of the installed object being flooded due to rainfall or the like, and is normally used as a veranda or deck with the waterstop portion 10 as a seat by opening the legs 30.

[0015] FIG. 1 is an explanatory diagram showing one embodiment of a water stop device 100 according to the present invention, in which (a) is a plan view, (b) is a front view, and (c) is a side view. FIG. 2 is an enlarged cross-sectional view taken along the line AA in FIG. 1. The water stop plate portion 10 is disposed across the width of an entrance to an installation, specifically, the entrance to a building or a gate of an exterior structure of a site, and is disposed at a predetermined height from the ground. Although it is preferable that the water stop plate portion 10 is high, it is not necessarily effective to make it extremely high considering the possibility of water ingress from other parts of the installation, and a height of 400 to 800 mm is preferable, and in this embodiment, it is about 600 mm. Here, the left-right direction, up-down direction, and front-back direction of the water stop device 100 are the same directions as the left-right direction, up-down direction, and front-back direction shown in FIG. 1 unless otherwise specified, and the following description will be based on this.

[0016] As shown in Figure 2, the waterstop plate portion 10 comprises a vertical plate portion 11 facing the entrance / exit of the installed object, a horizontal plate portion 12 formed from the lower end of the vertical plate portion 11 toward the front, and a lower plate portion 13 formed downward from the front side of the horizontal plate portion 12.

[0017] In this embodiment, the waterstop portion 10 is formed by combining a plurality of members whose longitudinal direction is the left-right direction. Specifically, the waterstop portion 10 is formed by combining a plurality of plate-like members 50 and sector-shaped members 60 each having a sector-shaped cross section.

[0018] Fig. 3 is an enlarged view of the plate-like member 50 in Fig. 2, and Fig. 4 is an explanatory diagram showing the engagement structure between the plate-like members 50 in Fig. 2. The plate-like member 50 has steps 51, 51 at the upper and lower ends. The step 51 at the upper end has a recess 52 on the front side and a protrusion 53 on the rear side, and the step 51 at the lower end has a recess 52 on the rear side and a protrusion 53 on the front side.

[0019] As a result, as shown in Fig. 4, by arranging the plate-like members 50, 50 one above the other and engaging the convex portion 53 on one side with the concave portion 52 on the other side at the opposing step portions 51, 51, the plate-like members 50 can be arranged successively in the vertical direction. In this embodiment, as shown in Fig. 3, three plate-like members 50 are arranged successively in the vertical direction to form the vertical plate portion 11 of the waterstop plate portion 10.

[0020] 5 is an enlarged view of the sector member 60 in FIG. 2, and FIG. 6 is an explanatory diagram showing the engagement structure between the plate member 50 and the sector member 60 in FIG. 2. The sector member 60 has a sector-shaped cross section with a central angle of about 90 degrees, and both ends of the sector shape have steps 61, 61 with a recess 62 on the central angle side and a protrusion 63 on the opposite side. In this embodiment, as shown in FIG. 6, one sector member 60 has a recess 62 and a protrusion 63 of the step 61 engaged with a protrusion 53 and a recess 52 of a step 51 of the lowest plate member 50 that are successively arranged in the vertical direction. As a result, the formation direction of the waterstop plate 10 is changed from the vertical direction to the front direction as shown in FIG. 2.

[0021] Fig. 7 is an explanatory diagram showing the engagement structure between the sector-shaped members 60 in Fig. 2. As shown in Fig. 7, on the front side of the sector-shaped member 60 that engages with the lowest plate-like member 50, a sector-shaped member 60 of the same shape engages with one convex portion 63 of each step 61, 61 in the other concave portion 62. As a result, the formation direction of the waterstop plate portion 10 is changed from the front direction to the downward direction, and these two sector-shaped members 60 form the side plate portion 12 and the lower plate portion 13 of the waterstop plate portion 10.

[0022] In this embodiment, as shown in FIG. 2, the step 51 of the topmost plate-like member 50 that is continuously arranged in the vertical direction is engaged with the step 61 of another sector-shaped member 60 .

[0023] In this embodiment, the plate-shaped member 50 and the sector-shaped member 60 are both hollow aluminum alloy members whose surfaces are coated with synthetic resin, but are not particularly limited to this embodiment. In addition, in Figures 4, 6, and 7, when the plate-shaped members 50 engage with each other, when the plate-shaped members 50 engage with the sector-shaped members 60, and when the sector-shaped members 60 engage with each other, packing may be placed between the members.

[0024] Fig. 8 is a rear view of Fig. 1. The base portion 20 is disposed on the rear side of the waterstop portion 10. In this embodiment, it has upper horizontal members 21 and lower horizontal members 22 disposed at an interval in the vertical direction, and vertical members 23 disposed at an interval in the width direction, and the upper horizontal members 21 and lower horizontal members 22 are joined to the vertical members 23. To explain in more detail, the upper horizontal member 21, lower horizontal member 22, and the two vertical members 23 located on both sides form an outer shape into a rectangle. The remaining two vertical members 23 are disposed between the two vertical members 23 on both sides.

[0025] 2, in the base portion 20, the lower cross member 22 is disposed forward of the upper cross member 21. The bottom plate member 24 is disposed rearward of the lower cross member 22 and below the upper cross member 21. The vertical members 23 are disposed between the lower surface of the upper cross member 21 and the upper surface of the bottom plate member 24, and are joined to the upper cross member 21, the bottom plate member 24, and the lower cross member 22, respectively.

[0026] The positional relationship between the waterstop portion 10 and the base portion 20 is such that the upper horizontal member 21 and the vertical member 23 of the base portion 20 are located behind the vertical plate portion 11 of the waterstop portion 10, and the lower horizontal member 22 of the base portion 20 is located below the horizontal plate portion 12. In other words, the horizontal plate portion 12 is placed on the lower horizontal member 22, and the upper horizontal member 21 and the vertical member 23 support the vertical plate portion 11 from the rear.

[0027] The waterstop portion 10 and the base portion 20 are connected by a side plate portion 40. As shown in Fig. 1, the side plate portion 40 is disposed at both the left and right ends of the waterstop portion 10 and the base portion 20, and is fastened to each of the waterstop portion 10 and the base portion 20 by fastening members.

[0028] As a specific fastening method, screws 41 as fastening members are screwed into screw holes 54, 64 formed along the longitudinal direction of the plate-like member 50 and the sector-shaped member 60 from through holes (not shown) penetrating the side plate portion 40 in the left-right direction, and screw holes (not shown) formed in the vertical members 23 at both side ends of the base portion 20. FIG. 1(c) shows the fastening position of the screw 41. As shown in FIG. 3 and FIG. 5, a plurality of screw holes 54 and screw holes 64 are formed for one plate-like member 50 and sector-shaped member 60, and they can be appropriately selected and used. Although not shown, the waterstop portion 10 and the base portion 20 may be fastened by screwing a tapping screw from the waterstop portion 10 toward the base portion 20.

[0029] Furthermore, in this embodiment, an elastically deformable elastic sheet material 71 is arranged between the side panel portion 40 and the water stop plate portion 10 and the base portion 20, thereby making it possible to prevent water from entering between the side panel portion 40 and the water stop plate portion 10 and the base portion 20.

[0030] Next, the water stop structure of the water stop device 100 with respect to the installation surface side of the installation location will be described. As shown in Fig. 2, the water stop plate portion 10 has a spacer 14 attached to the lower end portion of the lower plate portion 13. In this embodiment, the spacer 14 is continuously disposed in front of the lower cross member 22 of the base portion 20, and the height position of the lower end face of the spacer 14 is aligned with the height position of the lower end face of the lower cross member 22. An elastically deformable elastic sheet material 72 is attached to the lower end face of the spacer 14. The elastic sheet material 72 is attached from the lower end face of the spacer 14 to the lower end face of the lower cross member 22.

[0031] As a result, if it is assumed that after installation of the water-stopping device 100, water is submerged up to the middle of the vertical direction of the water-stopping device 100, the elastic sheet material 72 is placed on the installation surface, so even if the installation surface is uneven, a downward load is applied by the weight of the water-stopping device 100, and the elastic sheet material 72 elastically deforms to absorb the unevenness and is pressed against the installation surface, thereby preventing water from entering between the installation surface and the elastic sheet material 72 in the event of flooding.

[0032] In addition, water pressure is generated downwards on the side plate portion 12 and the lower plate portion 13 of the waterstop portion 10 due to infiltration of water, so that the elastic sheet material 72 and the elastic sheet material 72 press more strongly against the installation surface. In this embodiment, the lower plate portion 13 to which the spacer 14 is attached is attached with the sector member 60, and the sector member 60 is located above the front side of the spacer 14, so that a gap S is formed between the rear side of the spacer 14 and the sector member 60. Therefore, the load applied to the lower plate portion 13 acts biasedly on the front side of the spacer 14, so that the front side of the elastic sheet material 72 is easily pressed against the installation surface through the spacer 14, and water infiltration can be further suppressed. In other words, when water infiltrates from the front side of the elastic sheet material 72, the upper part of the waterstop portion 10 is easily loaded in the direction of falling toward the installation object, which promotes water infiltration from the installation surface side, but this embodiment can suppress this.

[0033] In this embodiment, since the spacer 14 is also elastically deformable, the load applied to the lower plate portion 13 is more likely to be transmitted through the spacer 14 to the elastic sheet material 72 located below it, making it easier for the front side of the elastic sheet material 72 to be pressed against the installation surface, thereby further suppressing water intrusion.

[0034] In addition, in this embodiment, as shown in Figures 2 and 8, an elastically deformable elastic sheet material 73 is attached to the underside of the bottom plate material 24 of the base portion 20, thereby absorbing unevenness on the ground side and preventing water from entering between the front and left and right side sides of the water-stopping device 100 and the installation surface.

[0035] Next, the water-stopping structure with respect to the installation object (e.g., entrance) side of the installation location will be described. As shown in Fig. 1 and Fig. 2, an elastic sheet material 74 having elasticity is attached to the rear side of the base part 20. Specifically, the elastic sheet material 74 having elasticity is attached to the vertical members 23, 23 and the upper horizontal member 21 on both ends of the base part 20 in the vertical direction of the surface on the installation object side. If the water-stopping device 100 is installed so that the elastic sheet material 74 abuts against the installation object (e.g., a gatepost), when water ingress occurs, the water pressure is applied from the water-stopping plate part 10 through the base part 20 to the elastic sheet material 74, which tends to press the installation object, making it difficult for water to infiltrate between the elastic sheet material 74 and the installation object.

[0036] 9 is an explanatory diagram of the leg 30 in FIG. 2, where (a) shows the leg 30 in a closed state and (b) shows the leg 30 in an open state. As shown in FIGS. 8 and 9, the leg 30 is attached to the base 20. In this embodiment, the leg 30 is attached in pairs to the two inner vertical members 23 of the four vertical members 23 of the base 20, one above the other. Specifically, the leg 30 is fixed to the vertical members 23 via a connecting metal fitting 31, and can change its position between a folded position along the longitudinal direction of the vertical members 23 with the connecting metal fitting 31 as an axis and an open position in which the tip of the leg 30 faces backward, as shown by the arrow.

[0037] Fig. 10 is a side view showing another state of use of the water stop device 100 of Fig. 1. In the pair of upper and lower legs 30, the lower leg 30 is arranged so that the height position of the lower surface of the elastic sheet material 73 of the bottom plate material 24 matches when in the open position. In other words, the elastic sheet material 75 is attached to the lower leg 30 at a position that becomes the lower surface side when in the open position. As a result, when using the water stop device 100, if the lower leg 30 is used in the open position and does not interfere with the installed object, the water stop device 100 is less likely to tip over towards the installed object.

[0038] Fig. 11 is a side view showing yet another state of use of the water stop device 100 of Fig. 1. The water stop device 100 can be used as a bench or deck by changing the legs 30 to the open position, tilting the water stop device 100, and standing it on the installation surface with the four legs 30. When using it for water stoppage again, simply change the legs 30 to the folded position. There are no particular limitations on the legs 30 as long as they are attached so as to be openable and closable.

[0039] As described above, Water stop device Although the present invention has been described based on the embodiments, the present invention is not limited to these embodiments. Various modifications that can be conceived by a person skilled in the art without departing from the gist of the present invention are also included in the scope of the present invention.

[0040] In this embodiment, the waterstop portion 10 is formed by combining and arranging the plate-shaped member 50 and the sector-shaped member 60, but the waterstop portion 10 may be formed as an integral unit. [Explanation of symbols]
