Description

本考案は、洪水時に河川やマンホール等から水が溢れ、家屋等に浸水する恐れがある際に玄関等に存置して浸水を防ぐ水嚢袋に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water bag bag that is left at an entrance or the like to prevent flooding when there is a risk of water overflowing from rivers, manholes, etc. during a flood and flooding a house or the like.

近年、気象温暖化が原因の一つとされる大雨による洪水が多発し、川の氾濫や雨水の処理不全による家屋等への浸水が大きな問題となっている。 2. Description of the Related Art In recent years, flooding due to heavy rains, which is considered to be one of the causes of climate warming, has occurred frequently, and flooding of houses due to flooding of rivers and incomplete treatment of rainwater has become a serious problem.

この浸水を防ぐには従来より土嚢が用いられることが通常であったが、土嚢を使用する場合、あらかじめ大量の土を準備しておかねばならないことや、個人が家庭で土を袋に詰める作業や持ち運んで所定の場所に設置することは大変な労力が必要であるし、女性や老人ではこのような作業はそもそも困難であり、危急を要する際には対処不能となる場合があった。 Traditionally, sandbags have been used to prevent this flooding, but when using sandbags, it is necessary to prepare a large amount of soil in advance, and the work of packing soil into bags by individuals at home. It requires a great deal of labor to carry the device and install it in a predetermined place, and it is difficult for women and elderly people to do such work in the first place.

また、土嚢使用後には土嚢に詰めた土の廃棄処分も問題となっていた。 Moreover, after using the sandbag, disposal of the soil filled in the sandbag has also been a problem.

最近では、土に代えて水を注入する水嚢が開発され、一般に知られるようになったが、現在知られているものでは次のような欠点があった。 Recently, a sac in which water is injected instead of soil has been developed and has become generally known, but currently known sacs have the following drawbacks.

特開2021-55274号公報 JP 2021-55274 A

特開2008-63925号公報 JP 2008-63925 A

特開2021-55274号公報には水嚢袋が記載しているが、水の袋への注入後、注入体とその取り付け状態の構成が不十分であるため、嚢の注入口周辺の接着端辺が変形したり、袋に想定以上の強い圧力がかかると注入体から内部の水が漏れるという欠点があった。 JP-A-2021-55274 describes a water bag, but after injection into the water bag, the configuration of the injection body and its mounting state is insufficient, so the adhesive end around the injection port of the bag There was a drawback that the water inside leaked from the injection body if the sides were deformed or if the bag was subjected to a stronger pressure than expected.

また、特開2008-63925号公報に記載の防災用水袋のように、バルブのようなプラスチック造形物の注水栓を取り付けたものも知られているが、これでは袋自体が高価となるとともに収納時にかさ張り、家庭で備え付けておくには不都合があった。 In addition, like the disaster prevention water bag described in Japanese Patent Application Laid-Open No. 2008-63925, there is also known a water filling plug of a plastic model such as a valve. It was sometimes bulky and inconvenient to keep at home.

本考案は、上述した従来知られている水嚢袋の欠点を克服し、注入された水が注入口より漏れることを防ぎ、かつ安価に構成され、さらには非使用時にはかさ張らず保管・収納できる水嚢袋を提供することを目的とするものである。 The present invention overcomes the above-mentioned drawbacks of the conventionally known water bladder bag, prevents the injected water from leaking from the injection port, is constructed at a low cost, and can be stored and accommodated without being bulky when not in use. It is an object of the present invention to provide a water bladder bag.

本考案の水嚢袋は、略同寸法の2枚の熱溶融性の矩形状プラスチックフィルムを重ね合わせてその4端辺を熱溶着により接着して密閉袋状となし、その一つの端辺に扁平筒状の逆流防止弁部材を具備してなる水嚢袋である。 The water bag of the present invention is made by superimposing two heat-fusible rectangular plastic films of approximately the same size and adhering the four edges by heat welding to form a sealed bag. The bladder bag is provided with a flat cylindrical backflow prevention valve member.

本考案によれば、大雨等による洪水の際に、家庭の水道の蛇口から一般に用いられるホースを逆流防止弁部材に挿入して水嚢袋に水道水を注入するだけで水嚢とすることができ、玄関や通用口等に置くことにより、洪水から浸水を防ぐことができる。 According to the present invention, in the event of flooding due to heavy rain or the like, a water bag can be made by simply inserting a hose generally used from a household water faucet into the check valve member and injecting tap water into the water bag bag. It is possible to prevent flooding from flooding by placing it at the entrance, side entrance, etc.

また、この水嚢袋のサイズを一般の土嚢袋のサイズより一回り小さく設定することにより、水嚢袋を土嚢袋に収納したのち水嚢袋に水を注入し、その後土嚢袋の口を通常の方法で縛ることにより、より構造的に外部の衝撃に耐えうる水害防止用の袋とすることができる。 In addition, by setting the size of this water bag one size smaller than the size of a general sandbag, water is injected into the water bag after storing the water bag in the sandbag, and then the mouth of the sandbag is opened normally. By tying the bag by the above method, it is possible to obtain a bag for preventing water damage that is more structurally resistant to external shocks.

図1は、逆流防止弁部材51を矩形フィルム状の袋本体1に取り付けた状態の正面図である。袋本体1は、最初の時点で略同寸法である2枚の熱溶融性の合成樹脂よりなる第1フィルム3と第2フィルム5が重ねられ、3端辺が熱溶着された構成となっている。この合成樹脂フィルム3,5は一定の引張強度を有する熱可塑性樹脂であればよく、例えばポリエチレン樹脂を用いることができ、望ましくはバイオマスポリエチレン樹脂用いることがよい。図中熱溶着部を符号7、9、11で示す。また、残りの一つの端辺は開口部13となっている。 FIG. 1 is a front view of a state in which a check valve member 51 is attached to a rectangular film-shaped bag body 1. FIG. The bag body 1 is initially constructed by stacking a first film 3 and a second film 5 made of heat-fusible synthetic resin and having substantially the same size, and heat-sealing the three edges. there is The synthetic resin films 3 and 5 may be any thermoplastic resin having a certain tensile strength, for example, polyethylene resin may be used, and preferably biomass polyethylene resin may be used. In the drawing, the heat-welded portions are denoted by reference numerals 7, 9, and 11. As shown in FIG. Also, the remaining one edge is an opening 13 .

逆流防止弁部材51を上記袋本体1に取り付ける場合には、逆流防止弁部材51を上記開口部13の所定位置に挿し込む。その際、後述する熱硬化性樹脂塗布部61,62を開口部13の溶着部に合わせる。この際、塗布部61,62の位置が判明しやすいように、塗布部を着色しておくことが望ましく、これによって逆流防止弁部材51の差込位置を決めることができる。次に、開口部13を全長にわたって熱溶着する。図中熱溶着部を符号15で示す。このようにして逆流防止弁部材51が袋本体1に取り付けられる。 When attaching the check valve member 51 to the bag body 1 , the check valve member 51 is inserted into the opening 13 at a predetermined position. At that time, thermosetting resin coated portions 61 and 62 to be described later are aligned with the welded portion of the opening 13 . At this time, it is desirable to color the application parts 61 and 62 so that the positions of the application parts 61 and 62 can be easily identified. Next, the opening 13 is thermally welded over its entire length. A heat welded portion is indicated by reference numeral 15 in the figure. The check valve member 51 is attached to the bag body 1 in this way.

逆流防止弁部材51において、熱硬化性樹脂塗布部61,62が設けられている部位は第1フィルム3と第2フィルム5が熱溶着により熱溶着部15が形成されても溶着されることはなく水注入路54が閉塞されることもない。また、後述するように逆流防止弁部材51の第3フィルム52は熱溶着により袋本体1の第2フィルム5に溶着され、第4フィルム53は熱溶着により袋本体1の第1フィルム3に溶着される。 In the check valve member 51, the portions where the thermosetting resin-coated portions 61 and 62 are provided are not welded even if the heat-welded portion 15 is formed by heat-welding the first film 3 and the second film 5. Also, the water injection passage 54 is not blocked. As will be described later, the third film 52 of the check valve member 51 is welded to the second film 5 of the bag body 1 by heat welding, and the fourth film 53 is welded to the first film 3 of the bag body 1 by heat welding. be done.

袋本体の寸法は、例えば縦60cm、横45cmとすることで、標準的な土嚢袋である縦62cm、横48cmの内部に収納することが可能であり、外的な衝撃から本考案の水嚢の破袋を防ぐことができる。また、袋本体を構成するフィルム3,5の厚さは前記縦横の寸法の大きさの場合、通常のバイオマスポリエチレン樹脂を使用すれば40μmのもので十分な強度を得ることが確認されている。 The size of the bag body is, for example, 60 cm long and 45 cm wide, so that it can be stored inside a standard sandbag of 62 cm long and 48 cm wide, and the water bag of the present invention can be protected from external impact. can prevent bag breakage. In addition, it has been confirmed that the thickness of the films 3 and 5 constituting the main body of the bag is 40 μm and sufficient strength can be obtained if an ordinary biomass polyethylene resin is used in the case of the size of the vertical and horizontal dimensions.

熱溶着部7,9,11,15の熱溶着部は、前記サイズと厚みの袋に水が注入された場合、その幅が4mm以上であれば破断することはない。 The thermally welded portions of the thermally welded portions 7, 9, 11 and 15 will not break if the width of the bag is 4 mm or more when water is poured into the bag having the above size and thickness.

次に逆流防止弁部材の構造について説明する。
図2は本実施の形態による逆流防止弁部材51の構成を示す正面図である。この逆流防止弁部材51は第3フィルム52と第4フィルム53を重ね合せた構成をなしている。上記第3フィルム52と第4フィルム53は左右両側部が熱溶着されている。図中熱溶着部を符号57、58で示す。上記第3フィルム52と第4フィルム53の間であって上記熱溶着部57と熱溶着部58との間が水注入路54となっている。上記熱溶着部57、58には内側に突出した複数個の枝状熱溶着部59が設けられている。この形状の熱溶着部59が存在することにより、逆流の防止効果を高めている。
Next, the structure of the check valve member will be described.
FIG. 2 is a front view showing the structure of the check valve member 51 according to this embodiment. This check valve member 51 has a structure in which a third film 52 and a fourth film 53 are superimposed. Both left and right sides of the third film 52 and the fourth film 53 are thermally welded. Reference numerals 57 and 58 denote thermally welded portions in the drawing. A water injection passage 54 is provided between the third film 52 and the fourth film 53 and between the thermally welded portion 57 and the thermally welded portion 58 . A plurality of branch-like heat-welded portions 59 projecting inward are provided on the heat-welded portions 57 and 58 . The presence of the thermally welded portion 59 having this shape enhances the effect of preventing backflow.

また、上記第4フィルム53は上記第3フィルム52に対して所定量短くなっており、第4フィルム53の図2中右端は第3フィルム52の右端に対して所定量ずれている。上記第4フィルム53の上端の位置が水注入口55となっている。上記第4フィルム53の上端を上記第3フィルム52の上端に対して所定量ずらすことにより、上記水注入口55の位置を特定し易くしている。 The fourth film 53 is shorter than the third film 52 by a predetermined amount, and the right end of the fourth film 53 in FIG. 2 is shifted from the right end of the third film 52 by a predetermined amount. A water inlet 55 is provided at the upper end of the fourth film 53 . By shifting the upper end of the fourth film 53 from the upper end of the third film 52 by a predetermined amount, the position of the water inlet 55 can be easily identified.

上記第3フィルム52の上記第4フィルム53側の面には熱硬化性樹脂塗布部61が設けられている。また、上記第4フィルム53の上記第3フィルム52側の面には熱硬化性樹脂塗布部62が設けられている。上記熱硬化性樹脂塗布部61と熱硬化性樹脂塗布部62は例えば輪転機による印刷により面状に設けることができ、熱溶着を施されても溶着されることはない。
なお、上記熱硬化性樹脂塗布部61,62の何れか一方でも非溶着特性を発揮することはできるが、本実施の形態の場合にはそれをより確実なものとすべく二重に設けている。
A thermosetting resin coating portion 61 is provided on the surface of the third film 52 on the fourth film 53 side. A thermosetting resin coating portion 62 is provided on the surface of the fourth film 53 on the third film 52 side. The thermosetting resin-applied portion 61 and the thermosetting resin-applied portion 62 can be provided in a planar manner by printing with a rotary press, for example, and will not be welded even if heat-sealed.
It should be noted that although either one of the thermosetting resin-applied portions 61 and 62 can exhibit the non-welding property, in the case of the present embodiment, two portions are provided in order to make it more reliable. there is

熱硬化性樹脂塗布部に用いられる熱硬化性樹脂は一般に知られている塗布可能な樹脂を用いることができ、例えばプロペン酸とそのエステルモノマーとの間の不飽和結合が架橋反応した結果生成されるポリマーであるアクリル樹脂を用いることができる。 As the thermosetting resin used in the thermosetting resin-coated part, a generally known resin that can be applied can be used, and for example, it is generated as a result of a cross-linking reaction of unsaturated bonds between propenoic acid and its ester monomer. Acrylic resin, which is a polymer that can be used, can be used.

なお、水注入口55を円形状に開口した際の内径は、通常の家庭用ホースの外径にあったものとすることが望ましく、例えば外径22mmのホースであれば、ほぼその外径と同等の寸法となるように熱溶着部57,58を設ければよい。 It is desirable that the inner diameter of the water inlet 55 when it is opened in a circular shape matches the outer diameter of a normal household hose. The thermally welded portions 57 and 58 may be provided so as to have equivalent dimensions.

上述した通りの本考案の実施態様の水嚢袋では、水を注入すると約13kg~15kgとなり、これを並置及び積み重ねることにより十分な浸水防止効果を得ることができる。 As described above, the water bladder bag of the embodiment of the present invention weighs about 13 kg to 15 kg when filled with water.

なお、本考案の水嚢袋は現在上市されている土嚢袋とともに使用することが耐性上望ましい。その際、まず水嚢袋を土嚢袋に入れ、その後逆流防止弁部材の注入口に水道の蛇口に通じたホースを差し込み、水を注入する。袋にはほぼ一杯に水が注入された後、ホースを抜けば逆流防止弁が水圧により緊密に閉じ水が漏れることはない。その後、土嚢袋の開口部を付属の紐等によって閉じることにより簡便で強靭な浸水防止用水嚢とすることができる。 In terms of durability, it is desirable to use the water bag of the present invention together with sandbags that are currently on the market. At that time, first, the waterbag is put into the sandbag, and then a hose connected to a water faucet is inserted into the injection port of the check valve member to inject water. After the bag is almost filled with water, when the hose is removed, the check valve is tightly closed by the water pressure, preventing water from leaking out. After that, by closing the opening of the sandbag with an attached string or the like, it is possible to obtain a simple and strong waterbag for preventing flooding.
