Description

  The present invention relates to a waterstop material for measures against water damage.

As a method of urgently preventing inundation due to the ingress of water from the entrances and exits of buildings such as houses, buildings, garages, etc. in the event of floods, such as tsunamis, floods, flooding of nearby rivers, and ruptures of main pipes, It is common to temporarily dam the water using a sandbag.
However, it is hard work to pile a lot of heavy sandbags at the entrances and exits of the above buildings, and it is difficult for a powerless person such as an elderly person, a child, or a woman to quickly install sandbags in an emergency.
In addition, sandbags need to be properly stacked, and water intrusion cannot be reliably prevented.
On the other hand, if the automatic doors and shutters in front of the doors and shutters are filled with waterproofing materials in preparation for typhoons and heavy rain, the automatic doors and shutters cannot be opened or closed until the disaster passes. It becomes impossible to go in and out of things.
For this reason, the waterproof device shown, for example in patent documents 1-4 is proposed as a simple flood damage prevention means replaced with a sandbag.

  Patent Document 1 discloses a water stop device installed at an entrance / exit having a floor surface, and shuts off the entrance / exit in a state of being horizontally placed on the floor surface and partitions an upstream side and a downstream side.

(A) is a schematic side view of the embodiment shown in FIG. 1, (B) is a schematic side view showing a use state at the time of the occurrence of water damage of (A).

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, for convenience of explanation, U is above the building w, S is below the building w, F is the front of the building w, B is the back of the building w, L is the left side of the building, R Is to the right of the building w.
In the following description, it is assumed that an opening k is provided on the front surface w1 of the building w. In other words, in the building w, the front surface w1 refers to the surface provided with the opening k. Therefore, the front surface w1 is not limited to the front surface of the building w, and may be the outer surface or the back surface of the building w.

(Basic configuration)
As shown in FIGS. 1 and 2, the water damage-preventing waterproofing material 1 is disposed in front of an opening k such as an entrance / exit of a building w, and includes a water-stop sheet 2 and a guide 3.

(Water stop sheet 2)
The waterproof sheet 2 is a flexible and waterproof sheet. A plastic sheet can be adopted as the water stop sheet 2. A laminate sheet such as a lami sheet (registered trademark) or an adhesive sheet such as sanitect (registered trademark) can be used for the water stop sheet 2.
However, the water stop sheet 2 is not limited to a plastic sheet as long as it prevents water from entering, and may be a cloth, paper, or rubber sheet. For example, the waterproof sheet 2 may be a cloth coated with a water repellent or oil paper.
The water-stop sheet 2 has a vertical and vertical width larger than the expected height of water immersion from the ground g, and a horizontal width that is larger than the left and right widths of the opening k that prevents water from entering. The waterstop sheet 2 is not particularly limited in shape as long as it has the above dimensions, but in this example, it is a substantially rectangular sheet having an upper side 21, a lower side 22, a left side 23, and a right side 24. .
The dimensions of the water stop sheet 2 may be adapted to the size of various sizes of shutters, automatic doors, and installation spaces on both sides of the doors.
There is no particular limitation on the size of the water-stop sheet 2, but the width of the 60 cm water-stop sheet 2 is large with respect to the size of the door to be installed. It is preferable to do this. Further, it is preferable that the vertical width is a size obtained by adding at least 1 m to the installation height. For example, it is preferable to set the height from 60 to 70 cm from the upper part of the installation position to the floor as a balance between strength and a height that can be crossed by a person entering and exiting from the opening k.
However, the waterproof sheet 2 is not limited to the above dimensional range as long as it extends over the left and right sides of the opening k and can be straddled as described above, and can be carried out even if it takes dimensions outside the above range. .
In this example, the lateral width of the waterproof sheet 2 is the same as or larger than the left and right widths in the longitudinal direction of the guide 3. However, as long as the lateral width of the water stop sheet 2 is larger than the left and right widths of the opening k, the water stop sheet 2 can be implemented even if it is smaller than the left and right widths of the guide 3.
The upper end portion of the water-stop sheet 2, that is, the upper side 21 side is fixed to the guide 3 by attachment means 7 such as an adhesive or an adhesive tape. For example, as the adhesive tape, a double-sided tape may be provided on one of the waterproof sheet 2 and the guide 3 and the waterproof sheet 2 may be attached to the guide 3. The adhesive tape may be provided on the guide 3 in advance, or may be provided on the waterstop sheet 2 conversely. Moreover, it can implement also as what prepares an adhesive tape at the time of installation.
The means 7 for attaching the waterstop sheet 2 to the guide 3 is not limited to the adhesive tape, and a chuck tape may be employed instead of the adhesive tape 7. In particular, it is convenient to employ a mounting means 7 that can remove the water-stop sheet 2 from the guide 3 during normal times, such as the adhesive tape 7 and the chuck tape.
Therefore, a raised surface tape is used as the attachment means 7, one of the raised surface tapes is provided on the guide 3, and the other one of the raised surface tapes is provided in the vicinity of the upper side 21 of the water blocking sheet 2. The waterproof sheet 2 may be detachably attached, and a snap may be employed as the attachment means 7.
The above-described attachment of the water stop sheet 2 to the guide 3 may be performed after the guide 3 is installed in the building during disaster prevention. However, if the water stop sheet 2 is provided on the guide 3 from the beginning, it is convenient to install the water stop sheet 2 simply by fixing the guide 3 to the building during disaster prevention. The attachment means 7 is not limited to a detachable means, and may be configured such that the water stop sheet 2 cannot be easily detached from the guide 3 after the water stop sheet 2 is once attached to the guide 3. The use of an adhesive can be exemplified as a means that cannot be removed.

(Guide 3)
The guide 3 fixes the water stop sheet | seat 2 to the outer side (front F side) of the opening k of the building w provided with closing means, such as a shutter.
The guide 3 is a bag-like body filled with gas. The guide 3 includes a valve at the gas inlet. As the valve, the guide 3 can be filled without causing gas to flow out when the water-stopping material 1 for water damage countermeasures is used, and after the water-stopping material 1 for water damage countermeasures is used, the gas easily filled with the fingertips can be filled outside the guide 3. It is convenient to provide a check valve (not shown) that can be discharged into the tank. By adopting the check valve, once the gas is injected into the guide 3 and used, the gas is discharged from the guide 3 through the check valve, and the guide 3 can be folded and stored in the other for the next use. Because. An existing one can be adopted as the check valve. By using an existing check valve, air can be discharged by inserting a cylindrical instrument such as a straw into the check valve.
However, the guide 3 may be filled with gas from the beginning, that is, when shipped as a product. Further, even if the guide 3 is provided with a valve and a user injects gas into the guide 3 at the time of use, the guide 3 can be implemented so that it cannot be discharged after gas injection. In particular, in the case where the water-stopping material 1 for water damage countermeasures is disposable, it is conceivable to employ the guide 3 filled with gas from the beginning or the guide 3 that cannot discharge the gas 3 as described above. It does not restrict | limit taking the same aspect in what reuses the material 1. FIG.
In this example, the guide 3 is formed in a bag shape with one or more flexible plastic sheets. However, the guide 3 may be made of a material other than plastic as long as the filled gas does not easily escape. For example, the guide 3 may be formed as a bag-like body with rubber, waterproof cloth or paper.

In this example, the inside of the guide 3 is a single bubble cushioning material partitioned into a plurality of vesicles 4, and each of the vesicles 4 is filled with the gas. The gas to be filled is air. However, the present invention can also be carried out by filling the vesicle 4 with an inert gas having a low flammability such as helium instead of air.
The plurality of vesicles 4 are arranged in parallel and extend to the left and right of the front surface w1 of the building w by attaching the guide 3 to the building w. A space between adjacent vesicles 4 is defined by a seal 5. The seal part 5 can be formed by heat sealing. In this example, the vesicles 4 are in communication with each other. In addition, it can be carried out on the assumption that the vesicles 4 are also airtightly partitioned.
When the plurality of vesicles 4 are partitioned in an airtight manner, a check valve is provided for each of the vesicles 4.

The left and right end sides of the guide 3 are provided with an arrangement portion 31 on the back surface of the guide 3. The arrangement | positioning part 31 is a site | part which can be attached to the building w front surface w1 located in the right and left of the opening k. Specifically, the left and right lengths of the guide 3, that is, the lateral width of the guide 3 is larger than the left and right widths of the opening k. When the guide 3 is passed to the front of the opening k, a portion of the guide 3 that is positioned on the front surface w1 of the left and right building w of the opening k is set as the placement portion 31.
As long as the arrangement portion 31 is provided, the size of each portion of the guide 3 is not particularly limited.
The guide 3 can be attached to the left and right of the opening k at the arrangement portion 31. Specifically, the arrangement portion 31 includes an attachment portion 6 for attaching the guide 3 to the building w.
In this example, the attachment portion 6 is an adhesive layer formed of an adhesive. When the waterproof material for water damage prevention 1 is not used, the adhesive layer is covered with a release paper, and when the guide 3 is attached to the building w, the release paper is peeled off from the adhesive layer, and the adhesive layer is removed from the front of the building w. What is necessary is just to stick to w1.
However, the attachment portion 6 is not formed as an adhesive layer from the beginning, but a tape having an adhesive layer such as a double-sided tape is attached to the arrangement portion 31 or the building w when the waterproof material 1 is used. In addition, the guide 3 may be attached to the building w. Moreover, it can implement also as what attaches an adhesive to the arrangement | positioning part 31 or the building w, and attaches the guide 3 to the building w at the time of use of the water stop material 1 for a flood damage countermeasure. In each case described above, the attachment portion 6 is a portion of the guide 3 that is adhered to the double-sided tape or the applied adhesive.
The front surface w1 of the building w described above may be a surface positioned outside the building from the closing means d. In addition to the wall surface of the building w, the shutter frame, the automatic door, or the door of the shutter, which is the closing means d. including.
Therefore, a well-known adhesive capable of fixing the guide 3 to the concrete of the building or the metal frame of the shutter or the door is adopted as the adhesive used as each adhesive layer or the adhesive applied as described above.

As shown in FIG. 3 (A), when a disaster occurs, the guide 3 is disposed in front of the opening k at a position higher than the expected height of the inundation of the building w, and is fixed to the building front surface w1 by the mounting portion 6. . The water stop sheet 2 is fixed to the lower front portion of the guide 3 or the bottom of the guide 3 by the mounting means 7 described above. Due to the fixing to the guide 3, the water-stop sheet 2 is suspended from the guide 3 toward the ground g over the left and right of the opening k, and the lower end side of the water-stop sheet 2, that is, the lower side 22 side is hung on the ground g. As shown in FIG. 3 (B), when a flood occurs, the water pressure is applied to the water-stop sheet 2 as indicated by the white arrow, and the water-stop sheet 2 is pressed to the front surface w1 side of the building w to guide the opening k. Sealing below 3 to suppress flooding.
In particular, until the occurrence of water damage after the installation of a water-stop material for countermeasures against water damage, the water-stop sheet 2 does not obstruct the opening and closing of the closing means d such as a door, and the door 3 may enter and exit from the opening k. it can.
After the disaster has passed, the guide 3 adhered to the building w at the attachment portion 6 may be peeled off from the building w to prepare for the next use.
