Description

  The present invention relates to a water stop device, and more particularly, to a water stop device that employs a simple connection structure and is excellent in water stop and durability.

  In recent years, record guerrilla heavy rains have occurred frequently for a short time in various places due to abnormal weather caused by global warming. As is well known, roads are being paved in urban areas, and since rainwater that has rained flows into the river from the sewerage facility almost without penetrating into the ground, the river overflows or sewers in a short time. Rainwater erupts from the facility, causing tremendous damage such as underfloor inundation and underfloor in various locations.

  Conventionally, during such floods, sandbags were piled up at buildings and underground entrances to create a water-impervious wall to prevent water from entering the building. However, since the sandbag is very heavy, it takes a lot of labor for the stacking work, and it is not easy to secure a storage place because it is bulky. Moreover, as mentioned above, recent flood damage often occurs within a short period of time, and if it takes time to carry out the sandbag from the storage location and stack it up, it will be flooded before the impermeable wall is constructed. It was not unusual.

  In view of such circumstances, a substantially L-shaped portable device in which a standing wall erected in a substantially vertical direction and a support plate disposed in a substantially horizontal direction are sandwiched between a flexible sheet and a substantially L-shaped support bracket. A waterproof wall (Patent Document 1), a water shielding device in which a rectangular flat plate and a flat plate are connected in a substantially L shape by a hinge have been proposed (Patent Document 2).

US Pat. No. 7,121,764 Japanese Patent Application No. 2001-140235

  Since the devices of Patent Document 1 and Patent Document 2 are lighter than sandbags, they are freed from the heavy labor of transporting a large number of sandbags from a storage location and constructing a water shielding wall as in the past. .

However, in the portable waterproof wall of Patent Document 1, since the standing wall and the support plate are simply sandwiched between the flexible sheet and the support bracket, the connection strength is very weak so that the waterproof wall can withstand water pressure. In order to achieve this, it is necessary to take measures such as connecting the standing wall and the support plate with a stick or providing an anchor on the ground, which increases the number of parts and increases the cost, and installation work is also required. There was a problem of becoming complicated.
Moreover, in the water shielding apparatus of the above-mentioned patent document 2, since there is a risk of flooding from the gap between the connecting portions of the flat plate, it is necessary to ensure water-stopping separately, and in addition, rusting occurs when the hinge is immersed in water. There was also a problem of end up. Furthermore, since the flat plate and the flat plate are connected only by a hinge, it cannot be said that the connection strength is sufficient.

  The present invention has been made in view of the above problems, and the problem to be solved is a water-stopping excellent in water-stopping and durability, which employs a simple but strong connection structure that is easy to install. To provide an apparatus.

  In order to achieve the above object, a water stop device according to the present invention is a water stop device that prevents water from entering from one side to the other, and is a vertical water stop surface that is erected in a substantially vertical direction with respect to an installation surface. And a transverse water face material arranged in a substantially horizontal direction with respect to the installation surface, and either one or both of the vertical water face material and the transverse water face material are inserted and retained. It is held by a possible insertion holding part, and the vertical water surface material and the horizontal water surface material are connected.

  In the water stop device of the present invention, it is preferable that the vertical water stop surface material and the horizontal water stop surface material are connected by a connecting member having an insertion holding portion. Moreover, it is preferable that the said connection member has a horizontal water stop material insertion holding part opened in the substantially horizontal direction, and it is more preferable that the said connection member has a vertical water stop material insertion holding part opened in the substantially vertical direction. . In particular, the connecting member has a lateral water surface material insertion holding portion and a vertical water surface material insertion holding portion, and the lower end portion of the vertical water surface material insertion holding portion is behind the horizontal water surface material insertion holding portion. It is preferable to be located at.

  The vertical waterstop material and the horizontal waterstop material constituting the waterstop device of the present invention are much smaller in volume and lighter than conventional sandbags, so that many sandbags can be stored as in the past. You are freed from the heavy labor of transporting out of the place and building the impermeable walls. And either one or both of the vertical waterstop surface material and the horizontal waterstop surface material is securely held by the insertion holding portion that can insert and hold the waterstop surface material, the vertical waterstop surface material and the horizontal waterstop surface material, Since these are firmly connected, there is no fear that the connection will be lost due to water immersion or water pressure without using a water-stopping member or a reinforcing member. In addition, since the connection of the vertical water surface material and the horizontal water surface material is completed by a simple operation of inserting either one or both into the insertion holder, it can be quickly installed in the event of a flood, Since the vertical water surface material and the horizontal water surface material can be disconnected and stored, it is easy to secure a storage location.

  In particular, in the waterstop device in which the vertical waterstop material and the horizontal waterstop material are connected by a connecting member having an insertion holding portion, for example, the vertical waterstop material and the horizontal waterstop material are formed of a lightweight material. In addition, a lightweight and high-strength water stop device can be easily constructed, for example, by forming a connecting member that requires the most strength from a high-strength material.

Further, the water stop device in which the connecting member has a horizontal water stop surface material insertion holding portion that is opened in a substantially horizontal direction, only inserts the horizontal water stop surface material into the horizontal water stop surface material insertion holding portion that is opened in a substantially horizontal direction. By simple work, we can hold side water surface material surely,
Furthermore, the water stop device in which the connecting member has a vertical water surface material insertion holding portion that is open in a substantially vertical direction, simply inserts the vertical water surface material into a vertical water surface material insertion holding portion that is open in a substantially vertical direction. The vertical water surface material can be reliably held by simple work.

  In a device in which a vertical water surface material and a horizontal water surface material are connected and integrated by a connecting member as in the water stopping device according to claim 2 or claim 3 of the present invention, the depth dimension (front and rear dimensions) of the connecting member. The longer the is, the more difficult it is for the vertical waterstop surface material to bend, and the strength of the entire waterstop device is improved, reducing the risk of flooding and damage. Therefore, the connecting member has a lateral water surface material insertion holding portion and a vertical water surface material insertion holding portion, and the lower end portion of the vertical water surface material insertion holding portion is behind the horizontal water surface material insertion holding portion. If the lower end of the vertical water surface material insertion holder is located behind the horizontal water surface material insertion holder, the depth dimension of the connecting member will inevitably become longer. The material becomes difficult to bend, and the strength and stability of the water stop device are further improved. In addition, since the lower end of the vertical water stop face material is located at a low position, the overall height of the water stop device can be suppressed.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

  The water stop device 10 of the present invention shown in FIG. 1 includes a vertical water stop material 1 erected in a substantially vertical direction with respect to an installation surface, and a horizontal water stop material 2 disposed in a substantially horizontal direction with respect to the installation surface. In order to prevent water from entering from one (for example, the outdoor side) to the other (for example, the indoor side). belongs to.

  In the present embodiment, the longitudinal water stop material 1 is a translucent panel obtained by extrusion-molding a lightly colored translucent resin. As shown in FIG. 3, between the pair of surface materials 1 a and 1 a. By forming a plurality of partition walls (horizontal partition walls 1b, vertical partition walls 1c, diagonal partition walls 1d), a large number of hollow portions 1e penetrating in the width direction of the vertical waterstop material 1 are formed. Yes. In this way, by forming a large number of hollow portions 1e by the horizontal, vertical, and diagonal partition wall portions 1b, 1c, and 1d, the vertical water stop material 1 has a high-strength and lightweight honeycomb structure (hollow structure). The labor required for carrying from the storage location and installation work is greatly reduced. Moreover, by making the vertical water surface material 1 have translucency, it is freed from the feeling of blockage when it is installed, and the water level can be easily confirmed from the side opposite to the water ingress side (for example, indoor side). Will be able to.

  As shown in FIGS. 2 and 3, a connecting convex portion 1 f to be inserted into a vertical water surface material insertion holding portion 3 b of the connecting member 3 described later is provided at the lower end of the vertical water surface material 1 having the above-described configuration. As shown in FIG. 4 and FIG. 5, the connecting convex portion 1 f is formed in a convex shape having a substantially elliptical cross section formed integrally with the vertical water stop material 1. It is formed continuously over the entire width of the lower end of 1.

  Next, the horizontal water stop material 2 arranged in a substantially horizontal direction with respect to the installation surface is the same as the vertical water stop material 1 and is used after being rotated by 90 °. That is, as shown in FIG. 3, a plurality of partition walls (vertical partition walls 2b, horizontal partition walls 2c, and diagonal partition walls 2d) formed between the pair of surface materials 2a and 2a in the width direction. A large number of hollow portions 2e are formed, thereby realizing a hollow structure having high strength and light weight. Further, at the rear end of the lateral water surface material 2, a convex connecting convex portion 2 f having a substantially elliptical cross section formed integrally with the lateral water surface material 2 is provided at the rear end of the lateral water surface material 2. It is formed continuously over the entire width.

As the material resin for the vertical water surface material 1 and the horizontal water surface material 2, various thermoplastic resins such as polyvinyl chloride, polyacryl, polyolefin, and polyester can be used, and among them, a polycarbonate resin that is a kind of polyester. Is particularly preferably used. This is because the polycarbonate resin has a good balance of strength, moldability, price, etc., and can produce the high-quality vertical water surface material 1 and the horizontal water surface material 2 relatively inexpensively. Such a polycarbonate vertical water surface material 1 and / or a horizontal water surface material 2 may contain an ultraviolet absorber or a light stabilizer to enhance weather resistance.
In addition, the material resin of the vertical water surface material 1 and the horizontal water surface material 2 can be formed of FRP or metal in addition to the synthetic resin as described above, and the material is not particularly limited. . Moreover, in this embodiment, although the vertical water surface material 1 and the horizontal water surface material 2 use the completely same thing, the vertical water surface material 1 and the horizontal water surface material 2 do not need to be the same, In particular, the lateral water surface material 2 that does not require as much strength as the vertical water surface material 1 may use, for example, a thin flat plate or slope.

  As shown in FIG. 1, the vertical water stop material 1 and the horizontal water stop material 2 are connected in a substantially L shape by a connecting member 3. As shown in FIG. 3, the connecting member 3 has a horizontal water stop surface material insertion holding portion 3 a that is open in a substantially horizontal direction so that the connection convex portion 2 f of the horizontal water stop surface material 2 can be inserted and held on the front surface side thereof. A vertical waterstop material insertion holding portion 3b that is open in a substantially vertical direction that can be inserted and held by the connecting convex portion 1f of the vertical waterstop material 1 is formed on the upper surface side. The lower end portion of the vertical water surface material insertion holding portion 3b of the connecting member 3 is formed to be positioned behind the horizontal water surface material insertion holding portion 3a.

The transverse water face material insertion holding part 3a and the vertical water face material insertion holding part 3b (hereinafter referred to as the insertion holding parts 3a and 3b together unless otherwise specified) are connected to the horizontal water face material 2. The convex part 2f and the connecting convex part 1f of the longitudinal water surface member 1 (hereinafter referred to as the connecting convex parts 1f and 2f together unless otherwise specified) are fitted into a substantially elliptical annular concave shape. The lateral water blocking surface material insertion holding portion 3 a and the vertical water blocking surface material insertion holding portion 3 b are formed integrally with the connecting member 3.
In addition, the said connection convex part 1f, 2f and the insertion holding | maintenance part 3a, 3b are the vertical water stop surface material 1 and the horizontal water stop surface material 2 (Hereafter, these are called the water stop surface materials 1 and 2 unless there is special circumstances. ) And the connecting member 3, but separate connecting convex portions 1 f and 2 f and insertion holding portions 3 a and 3 b may be attached to the water-stopping surface materials 1 and 2 and the connecting member 3 later. .

  As shown in FIG. 5, the thickness t of the connecting convex portions 1f and 2f is formed to be larger than the dimension w of the opening front of the insertion holding portions 3a and 3b. Therefore, if the connecting projections 1f and 2f are normally pressed against the insertion holding portions 3a and 3b of the connecting member 3, the thickness t of the connecting projections 1f and 2f is set to the insertion holding portions 3a and 3b. Therefore, the connecting convex portions 1f and 2f and the insertion holding portions 3a and 3b are not connected (can be connected by being slid and inserted from the side), and it is difficult to say that the workability is excellent. Therefore, in the present embodiment, the longitudinally facing water surface material 1 (the lateral water blocking surface material 2) is obtained by making the connecting convex portions 1f and 2f and the insertion holding portions 3a and 3b elastically deformable and reversible. Are pressed toward the vertical water stop surface material insertion / holding portion 3b (horizontal water stop surface material insertion / holding portion 3a) from the upper side to the lower side (front to rear), and the connecting convex portions 1f, 2f and the insertion holding portions 3a, 3b Are connected.

That is, since the connecting convex portions 1f and 2f are integrally formed with the water-stop surface materials 1 and 2 made of polycarbonate or the like as described above, the connecting convex portions 1f and 2f are also of the same type of material resin. Formed from. As is well known, such a material resin can be elastically deformed / restored. In addition, the connecting convex portions 1f and 2f of the present embodiment are hollow as shown in FIGS. Since the thickness is about 0.3 mm to 1.5 mm in order to make elastic deformation easy to occur, elastic deformation is more likely to occur. Similarly to the connecting convex portions 1f and 2f, the insertion holding portions 3a and 3b are also formed in a hollow shape. Therefore, the vertical water surface material insertion holding part 3b (horizontal water stop surface) of the connecting member 3 located below (rear) is connected to the connection convex portion 1f (connection convex portion 2f) of the vertical water surface material 1 (horizontal water surface material 2). When pressed against the material insertion holding portion 3a), not only the connecting convex portions 1f and 2f but also the insertion holding portions 3a and 3b start to deform, and the thickness t of the connecting convex portions 1f and 2f is equal to the opening opening of the insertion holding portions 3a and 3b. Even if it is larger than the dimension w, the thickness t of the connecting projections 1f, 2f is reduced and the dimension w of the opening opening of the insertion holding portions 3a, 3b is increased, thereby connecting the connecting projections 1f, 2f and the insertion holding portions 3a, 3b. It can be connected. When the connecting convex portions 1f, 2f and the insertion holding portions 3a, 3b are connected, the connecting convex portions 1f, 2f and the connected portion 3 are restored and return to their original shapes, so that the connecting convex portions 1f, 2f And the gap between the insertion holding portions 3a and 3b is completely eliminated, and it is possible to reliably prevent water from entering from the connected portion.
In addition, that the insertion holding parts 3a and 3b are formed in a hollow shape means that the connecting member 3 constituting the periphery of the insertion holding parts 3a and 3b is formed in a hollow shape.

  As described above, the lower end portion of the vertical water surface material insertion holding portion 3b of the connecting member 3 is formed to be located behind the horizontal water surface material insertion holding portion 3a. As in the present invention, in the device in which the longitudinal water surface material 1 and the lateral water surface material 2 are connected and integrated by the connecting member 3, the longitudinal water surface material becomes longer as the depth dimension (front and rear dimensions) of the connecting member 3 becomes longer. 1 becomes difficult to bend, the strength of the water stop device 10 as a whole is improved, and risks such as water immersion and breakage are reduced. Therefore, if the vertical water stop material insertion holding part 3b and the horizontal water stop material insertion holding part 3a are formed in such a positional relationship, the depth dimension of the connecting member 3 is inevitably increased, so that the vertical water stop material 1 bends. It becomes difficult and the strength and stability of the water stop device 10 are further improved. In addition, since the lower end of the vertical water stop face material 1 is located at a low position, the overall height of the water stop device 10 can be suppressed.

  However, as described above, the connecting member 3 of the water stop device 10 of the present invention is limited to one in which the lower end portion of the vertical water surface material insertion holding portion 3b is located behind the horizontal water stop surface material insertion holding portion 3a. For example, the vertical water stop material 1 and the horizontal water stop material 2 may be connected by a connecting member 3 as shown in FIGS. 6 and 7.

  That is, the connecting member 3 shown in FIG. 6 has a substantially L-shaped cross-sectional shape, and a lateral water stop surface material insertion holding portion 3a that allows the horizontal water stop surface material 2 to be inserted and held in the lower part on the front surface side. Is formed, and on the upper surface side, a vertical water stop material insertion holding portion 3b that can hold the vertical water stop material 1 by insertion is formed. When the longitudinal water surface material 1 and the lateral water surface material 2 are connected using such a connecting member 3, most of the rear end portion of the lateral water surface material 2 is inserted and held in the lateral water surface material insertion holding portion 3a. Therefore, when the weight of water is added to the upper surface of the lateral water stop face material 2, the water stop device 10 can be installed more stably.

  7 also includes a vertical water surface material insertion holding portion 3b and a horizontal water surface material so that the lower end portion of the vertical water surface material 1 is positioned above the rear end portion of the horizontal water surface material 2. Although the insertion holding part 3a is formed, the depth dimension of the connecting member 3 is short unlike the embodiment shown in FIG. Such a connection member 3 is slightly inferior in the connection strength between the water blocking surface materials 1, 2 and the connection member 3, but makes the water stop device 10 compact (especially the length in the front-rear direction can be suppressed). Is possible. In the water stop device 10 using such a connecting member 3, the lack of strength can be compensated by forming the connecting member 3 with a material having high strength and heavy weight.

  In addition, when the shape of the connecting convex portions 1f and 2f is formed in a convex shape having a substantially elliptical cross section as in this embodiment, the water-stopping surface material can be simply pressed as described above. Since the connection between 1 and 2 and the connecting member 3 is completed, there is a merit that the connecting operation becomes very easy. However, the shape of the connecting projections 1f and 2f is not limited to the substantially elliptical ring shape as long as the water blocking surface materials 1 and 2 and the connecting member 3 can be connected securely and firmly. For example, FIG. As shown, the connecting convex portions 1f and 2f are formed in a convex shape, the insertion holding portions 3a and 3b are formed in a concave shape, and the concave insertion holding portions 3a and 3b are connected to the convex connecting convex portions 1f and 3f. 2f may be slid and inserted from the side, and the vertical water stop material 1, the horizontal water stop material 2 and the connecting member 3 may be connected.

  Since the water stop device 10 having the above-described configuration uses the high-strength and lightweight water stop surface materials 1 and 2 having a hollow structure, the water stop device 10 can be carried and installed in various places. Therefore, the dimensions may be appropriately selected according to the installation location, but considering the transportability and installation workability, the width is about 50 to 250 cm and the height is about 20 to 150 cm (the water level is increased). A height that does not overflow even if used) is preferably used. Of course, there are many cases where the range for preventing water from entering from one side to the other is wider than the width dimension. In such a case, a plurality of water stop devices 10 having the above dimensions are connected to the left and right. By doing so, what is necessary is just to respond. The right and left connection between the water stop devices 10 may be any method and is not particularly limited. Moreover, in order to more reliably prevent movement of the water stop device 10 due to water pressure and water flow, a pressing member (not shown) that presses the water stop device 10 (particularly the lateral water stop face material 2) downward is placed, You may provide the location which fits and fixes this press member on the upper surface of the water stop apparatus 10 (horizontal water stop surface material 2).

FIG. 9 is an exploded perspective view showing a water stop device according to a reference example of the present invention.

The water stop device 10 of the reference example shown in FIG. 9 is different from the water stop device 10 shown in FIGS. 1 to 8 described above, without using the connecting member 3, the vertical water stop material 1 and the horizontal water stop surface material 2. Are concatenated.

That is, the transverse water face material 2 of the present reference example uses a slope having a front and lower inclined surface, and the connecting convex portion 1f of the vertical water face material 1 is inserted over the entire width of the rear end portion. A vertical water surface material insertion holding portion 3b that can be held is formed. Thus, the water stop device 10 in which the vertical water stop material insertion holding portion 3b is formed on the lateral water stop material 2 has a slightly lower connection strength than the water stop device 10 shown in FIGS. However, even if the connecting member 3 is not used separately, one simple operation of pressing the connecting convex portion 1f of the vertical water surface material 1 downward from above the vertical water surface material insertion holding portion 3b of the horizontal water surface material 2 is possible. The vertical water stop material 1 and the horizontal water stop material 2 can be connected only by work. Moreover, if the horizontal water surface material 2 is installed, it can also be used as a slope, and the vertical water surface material 1 and the horizontal water surface material 2 can be used by carrying the vertical water surface material 1 from the storage location only during a flood. It becomes possible to connect. Further, when a slope is used for the lateral water surface material 2, water pressure is applied to the lateral water surface material 2 from when the water level is low. When water pressure is applied to the lateral water stop material 2 in this manner, a force that presses the lateral water stop material 2 downward acts, so that there is an advantage that the water stop device 10 can be installed more stably. .

As in the reference example shown in FIG. 9 described above, the water stop device 10 of the present reference example connects the vertical water stop material 1 and the horizontal water stop material 2 without using the connecting member 3. That is, as shown in FIG. 10, the slope-shaped lateral waterstop material 2 is used, and the connecting convex portion 2 f is formed over the entire width of the rear end portion. And the horizontal water surface material insertion holding | maintenance part 3a which inserts this connection convex part 2f is formed in the lower end part by the side of the front surface of the vertical water surface material 1.
