Description

本発明は、止水装置に関し、更に詳しくは、一方から他方への水の浸入を、シンプルな構造の装置を用いて確実に阻止することのできる止水装置に関するものである。 The present invention relates to a water stop device, and more particularly, to a water stop device that can reliably prevent water from entering from one side to the other using a device having a simple structure.

昨今、地球温暖化が要因の一つとされる異常気象に伴い、各地で短時間の記録的なゲリラ豪雨が頻発している。周知のように、都市部では道路の舗装化が進んでおり、降雨した雨水は殆ど地中に浸透することなく、下水道施設から河川へと一気に流入するため、短時間で河川が氾濫したり下水道施設から雨水が噴き出したりして、各地で床下浸水や床上浸水などの甚大な被害を出している。 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.

従来、このような水害時には、土嚢を建物や地下の出入口等に積み上げて遮水壁を作り、建物等の内部への浸水を防いでいた。しかしながら、土嚢は非常に重いため、積み上げ作業には大変な労力を要し、また、嵩張るため保管場所の確保も容易ではなかった。しかも、上記のように、昨今の水害は短時間の内に被害が出ることが多く、土嚢を保管場所から運び出して積み上げる作業に時間を要すると、遮水壁を構築するまでに浸水してしまうことも珍しくなかった。 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.

かかる事情に鑑みて、Ｌ字型の遮水板の水平面に補給式吸水シートを取付けると共に、遮水板の立設面に自給式吸水シートを取付けてなる遮水装置が提案されている（特許文献１）。 In view of such circumstances, there has been proposed a water shielding device in which a replenishing water absorbing sheet is attached to the horizontal surface of an L-shaped water shielding plate and a self-contained water absorbing sheet is attached to a standing surface of the water shielding plate (patent) Reference 1).

上記特許文献１の遮水装置は、吸水シートが水分を吸収していない状態では、比較的軽量のため、従来のように、多数の土嚢を保管場所から運び出して遮水壁を構築するという重労働から解放されるものであった。また、その機能面においても、装置を設置した際に、補給式吸水シートの注入口より水を注入することにより重量が増して、安定感と水密性が向上し、水位が自給式吸水シートまで達すると、自給式吸水シートが水を吸水して重量がより一層増加し、それに伴い安定感と水密性がさらに向上するというものである。 Since the water impervious device of the above-mentioned Patent Document 1 is relatively light when the water absorbing sheet does not absorb moisture, as in the past, a heavy labor of carrying out a large number of sandbags from a storage place to construct a water impervious wall. It was to be released from. Also, in terms of its function, when the device is installed, water is injected from the inlet of the replenishing water absorbent sheet, the weight increases, stability and water tightness are improved, and the water level reaches the self-contained water absorbent sheet. When it reaches, the self-contained water-absorbing sheet absorbs water and the weight further increases, and accordingly, the sense of stability and water tightness are further improved.

特開２００１−１４０２３５号公報JP 2001-140235 A

しかしながら、上記特許文献１の遮水装置は、装置を設置する際に、補給式吸水シートの注入口より水を注入するという工程が必要となるため、その分の余計な時間と手間がかかるという問題があった。また、吸水シートに水が吸収されるようにするためには、高分子吸収剤や膨縮可能な透水性の袋などの特殊材料を用いる必要があることから、コストがかかるという問題もあり、さらに、吸水シートの吸水性能は、高分子吸収剤に依存することから、吸水性能が一定せずに不安が残るものであった。 However, the water-impervious device disclosed in Patent Document 1 requires a process of injecting water from the inlet of the replenishing water-absorbing sheet when the device is installed. There was a problem. In addition, in order to allow water to be absorbed by the water-absorbent sheet, it is necessary to use a special material such as a polymer absorbent or a water-permeable bag that can be expanded and contracted. Furthermore, since the water absorption performance of the water absorbent sheet depends on the polymer absorbent, the water absorption performance is not constant and anxiety remains.

本発明は上記の問題に鑑みてなされたもので、その解決しようとする課題は、コストの増加なしに容易且つ迅速に設置することができ、水が押し寄せた初期の段階から、装置の重量が確実に増加して、水密性が向上すると共に固定具等を用いなくとも流されることがない、浸水の危険性が極めて低い止水装置を提供することにある。 The present invention has been made in view of the above problems, and the problem to be solved is that it can be easily and quickly installed without an increase in cost, and the weight of the apparatus is reduced from the initial stage when water has rushed. An object of the present invention is to provide a water-stopping device that is surely increased and has improved water tightness and is not flushed without using a fixture or the like, and has a very low risk of inundation.

上記目的を達成するため、本発明に係る止水装置は、一方から他方への水の浸入を阻止する止水装置であって、上記止水装置の内部に水を導入する開口部が、止水装置の下部であって水の浸入側に形成されていることを特徴とするものである。 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 an opening for introducing water into the water stop device has a stop. It is a lower part of the water device and is formed on the water ingress side.

本発明の止水装置においては、上記開口部が止水装置の前面側に形成されていることが好ましい。また、上記止水装置が縦止水面材と枠材とを備え、該枠材は中空筒状のものであって、その上端部に上記縦止水面材を挿入する挿入部が形成されていると共に、前面側に開口部が形成されており、上記開口部と上記挿入部が、枠材の内部で連通していることが好ましく、上記開口部が複数形成されており、少なくとも２つの開口部が連通していることがより好ましい。 In the water stop device of the present invention, the opening is preferably formed on the front side of the water stop device. The water stop device includes a vertical water surface member and a frame member, and the frame member has a hollow cylindrical shape, and an insertion portion for inserting the vertical water stop surface member is formed at an upper end portion thereof. In addition, an opening is formed on the front side, and it is preferable that the opening and the insertion portion communicate with each other inside the frame member, and a plurality of the openings are formed, and at least two openings are formed. Is more preferably communicated.

本発明の止水装置は、止水装置の水が浸入する側の下部に、内部に水を導入する開口部が形成されているため、水害時は押し寄せた水が該開口部より導入されて止水装置の重量が増加する。装置の重量が増加すると、設置面に対して装置を鉛直方向に押し付ける力が作用し、安定感が増すと共に水密性も向上することから、別途固定具等を用いなくとも、流される心配なくして止水装置を設置することができる。このように本発明は、注入口より水を注入する工程を省くことができ、単に建物や地下の出入口等の前に装置を載置するという容易な作業で浸水を確実に防ぐことができるため、短時間の内に多くの被害をもたらす昨今の水害にも十分に対応することができる。また、従来のように、高分子吸収剤等の特殊な材料を必要としないため、余計なコストがかからず、吸水性能を特殊な材料に依存することがないため、水が押し寄せた初期の段階から、安定的に浸水を防ぐことができる。 In the water stop device of the present invention, since an opening for introducing water is formed in the lower part of the water stop device on the side where water enters, the water that has been pushed in is introduced from the opening during a flood. The weight of the water stop device increases. When the weight of the device increases, the force that presses the device in the vertical direction acts on the installation surface, which increases the sense of stability and improves watertightness. A water stop device can be installed. As described above, the present invention can omit the step of injecting water from the inlet, and can reliably prevent inundation by an easy operation of simply placing the device in front of a building or underground entrance / exit. It is possible to cope with the recent flood damage that causes a lot of damage within a short time. In addition, unlike conventional materials, no special materials such as polymer absorbents are required, so there is no extra cost and water absorption performance does not depend on special materials. From the stage, water can be stably prevented.

また、上記開口部が止水装置の前面側に形成されている止水装置は、最も水が浸入し易い位置に開口部が形成されているため、水が押し寄せた初期の段階から、より確実に水を止水装置の内部に導入して、重量を増加させることができる。 Further, the water stop device in which the opening is formed on the front side of the water stop device has an opening formed at a position where water is most likely to enter. Water can be introduced into the water stop device to increase the weight.

さらに、上記止水装置が縦止水面材と枠材とを備え、該枠材は中空筒状のものであって、その上端部に上記縦止水面材を挿入する挿入部が形成されていると共に、前面側に開口部が形成されており、上記開口部と上記挿入部が、枠材の内部で連通している止水装置は、次のようなメリットがある。即ち、止水装置において、水が押し寄せた際に、最も水圧が加わる部分は装置の下端部である。そこで、止水装置を縦止水面材と枠材から構成し、水圧が最も加わる下端部に位置する枠材を高強度の材料で形成し、枠材程の強度が必要とされない縦止水面材を軽量な材料で形成することにより、水圧に十分に耐え得る装置を、最大限軽量に製造することが可能となる。勿論、枠材と縦止水面材とは、開口部及び挿入部で連通していることから、導入された水により装置の重量は確実に増加して、安定感に問題もない。 Further, the water stop device includes a vertical water stop surface member and a frame member, the frame member has a hollow cylindrical shape, and an insertion portion for inserting the vertical water stop surface member is formed at an upper end portion thereof. In addition, the water stop device in which an opening is formed on the front surface side and the opening and the insertion portion communicate with each other inside the frame member has the following merit. That is, in the water stop device, the portion to which the water pressure is most applied when the water is pushed is the lower end portion of the device. Therefore, the waterstop device is composed of a vertical waterstop material and a frame material, and the frame material located at the lower end where the water pressure is most applied is formed of a high-strength material, so that the strength of the vertical waterstop material is not required. It is possible to manufacture a device that can sufficiently withstand the water pressure with the lightest material. Of course, since the frame member and the vertical water surface member communicate with each other at the opening and the insertion portion, the weight of the apparatus is surely increased by the introduced water, and there is no problem in stability.

また、水害とは、常に一定方向から水が押し寄せてくるとは限らないものであり、開口部が１つしか形成されて装置の場合には、水が上手く装置内部に導入されない恐れも生じるが、上記開口部が複数形成されており、少なくとも２つの開口部が連通している止水装置のように、開口部が複数形成されていると、どの方向から水が押し寄せてきたとしても、装置内部に水を導入することができる。そして、少なくとも２つの開口部が連通しているため、１つの開口部から導入された水は、連通するもう１つの開口部まで導かれ、例えば、装置の右側だけが重く、左側は軽いなど、重量バランスが狂うといった不具合を生じることもない。 In addition, water damage does not always impinge water from a certain direction, and in the case of a device having only one opening, water may not be introduced into the device well. If a plurality of openings are formed, such as a water stop device in which a plurality of openings are formed and at least two openings communicate with each other, no matter which direction the water has come from, the device Water can be introduced inside. And since at least two openings are in communication, water introduced from one opening is led to another opening that communicates, for example, only the right side of the device is heavy, the left side is light, etc. There is no problem that the weight balance goes wrong.

以下、図面を参照して本発明の具体的な実施形態を詳述する。 Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

図１に示す本発明の止水装置１０は、縦止水面材１と枠材２と横止水面材３とを備えた略Ｌ字型をした装置であって、一方から他方への水の浸入を阻止するために、例えば建物や地下の出入口等の柱体８，８間に設置されるものである。
ここで一方とは、水の浸入側（押し寄せてくる側）のことをいい、他方とは、水の被浸入側（本実施形態では屋内側）のことをいう。 A water stop device 10 according to the present invention shown in FIG. 1 is a substantially L-shaped device including a vertical water stop material 1, a frame member 2, and a horizontal water stop surface material 3, and water from one to the other. In order to prevent intrusion, it is installed between pillars 8, 8 such as a building or an underground entrance.
Here, one side refers to the water ingress side (the side that approaches), and the other refers to the water ingress side (in the present embodiment, the indoor side).

上記縦止水面材１は、淡く着色された透光性樹脂を押出成形した平面パネルであって、１対の表面材の間に、複数の隔壁部（横の隔壁部、縦の隔壁部、斜めの隔壁部）を形成することにより、縦止水面材１の鉛直方向に貫通する多数の中空部が形成されたものである。このように横、縦、斜めの隔壁部によって多数の中空部を形成すると、縦止水面材１が軽量且つ高強度な中空構造となるため、保管場所からの持ち運びや設置作業に要する労力を大幅に軽減するだけでなく、後述するように、その内部に水を導入することで、止水装置１０の重量を増加させることができるようになる。また、縦止水面材１が透光性を有するため、水の被浸入側（ここでは屋内側）から、水位を容易に把握することができるようにもなっている。本実施形態の縦止水面材１は、軽量なポリカーボネート樹脂により成形されているが、その他にも塩化ビニル樹脂やポリアミド樹脂等の合成樹脂で成形してもよく、重量が増加するため運搬性等が多少劣ることになるが、ステンレスやアルミなどの金属製のものであってもよい。 The vertical water stop material 1 is a flat panel obtained by extruding a lightly colored translucent resin, and a plurality of partition walls (horizontal partition walls, vertical partition walls, By forming the slanted partition wall portion, a large number of hollow portions penetrating in the vertical direction of the longitudinal water surface material 1 are formed. If a large number of hollow portions are formed by the horizontal, vertical, and oblique partition walls in this way, the vertical water surface material 1 has a lightweight and high-strength hollow structure, which greatly increases the labor required for carrying from the storage location and installation work. As will be described later, the weight of the water stop device 10 can be increased by introducing water therein. In addition, since the vertical water surface material 1 has translucency, the water level can be easily grasped from the water ingress side (here, the indoor side). The vertical water surface material 1 of the present embodiment is formed of a lightweight polycarbonate resin, but may be formed of a synthetic resin such as a vinyl chloride resin or a polyamide resin. However, it may be made of a metal such as stainless steel or aluminum.

上記の縦止水面材１は、図２に示すように、枠材２により保持されている。この枠材２は、その上端部に縦止水面材１の下端部を挿入（嵌挿）する、凹空状の挿入部２ａが形成された中空筒状のものであって、図１に示すように、その前面側、即ち、水の浸入側には、止水装置１０の内部に水を導入するための開口部４が複数（本実施形態では３つ）形成されている。この開口部４は、枠材２の前面側を方形状に切り欠くことにより形成されたものであり、上記のように、枠材２が中空筒状であることから、これら３つの開口部４は、枠材２内部で全て連通している。枠材２の体積がおおよそ１０００〜７０００ｃｍ^３であるため、枠材２内部が導入された水によって満水になると、１〜７ｋｇ程度、枠材２の重量が増加することとなる。
なお、開口部４は、水を導入し易い形状であれば、本実施形態のように、方形状に限定されるものではなく、円形やその他の形状であっても構わないものであり、その個数も必要に応じて適宜増減すればよい。また、開口部４を形成する箇所は、水の浸入側であれば枠材２の前面側に限定されるものではない。例えば止水装置１０の側面下部であってもよく、前面側と側面の双方に形成してもよい。この開口部４を止水装置１０の側面下部に形成する場合は、後述する端板５に方形状又は円形状の孔を穿孔すればよいのであって、端板５の開口部４より導入された水は、枠材２内部から縦止水面材１の中空部にも導入されるようになる。 The vertical waterstop material 1 is held by a frame material 2 as shown in FIG. This frame member 2 is a hollow cylinder having a hollow insertion portion 2a in which the lower end portion of the vertical water surface member 1 is inserted (inserted) into the upper end portion, and is shown in FIG. As described above, a plurality of (three in the present embodiment) openings 4 for introducing water into the water stop device 10 are formed on the front side, that is, the water ingress side. The opening 4 is formed by cutting out the front side of the frame member 2 into a square shape. Since the frame member 2 has a hollow cylindrical shape as described above, these three opening portions 4 are formed. Are all in communication within the frame member 2. Since the volume of the frame member 2 is approximately 1000 to 7000 cm ³ , when the inside of the frame member 2 is filled with water, the weight of the frame member 2 increases by about 1 to 7 kg.
Note that the opening 4 is not limited to a rectangular shape as in the present embodiment as long as water is easily introduced, and may be a circular shape or other shapes. The number may be increased or decreased as necessary. Moreover, if the location which forms the opening part 4 is a water infiltration side, it will not be limited to the front side of the frame material 2. FIG. For example, the lower part of the side surface of the water stop device 10 may be used, and it may be formed on both the front side and the side surface. When the opening 4 is formed in the lower part of the side surface of the water stop device 10, a square or circular hole may be perforated in the end plate 5 described later, and is introduced from the opening 4 of the end plate 5. Water is also introduced into the hollow portion of the vertical water surface material 1 from the inside of the frame material 2.

上記開口部４と挿入部２ａは、図４に示すように、枠材２の内部で連通している。従って、水害時に、開口部４より導入された水は挿入部２ａに達し、その挿入部２ａに挿入される上記縦止水面材１が、多数の中空部が形成されたものであることと相俟って、該水は挿入部２ａを経由して、さらに縦止水面材１の内部にも導入される。上記のように、枠材２は、縦止水面材１を挿入する挿入部２ａが形成されている関係から、その上端は開口しているが、下端は底板２ｂにより閉口しているため、止水装置１０は枠材２と縦止水面材１の内部に導入された水の重さ分だけ重量が増加する。従って、止水装置１０の自重に導入された水の重さがプラスされた重量分が底板２ｂに加わり、その底板２ｂにより設置面（地面）を押圧する力が作用するため、土嚢等と比較すると遥かに軽量であるにも拘わらず、固定具等を用いなくとも水流に負けて止水装置１０が流されてしまう心配がない。 As shown in FIG. 4, the opening 4 and the insertion portion 2 a communicate with each other inside the frame member 2. Therefore, at the time of flooding, the water introduced from the opening 4 reaches the insertion portion 2a, and the vertical water surface material 1 inserted into the insertion portion 2a is in combination with a number of hollow portions formed. Thus, the water is further introduced into the longitudinal water surface material 1 via the insertion portion 2a. As described above, the frame member 2 has an opening at the upper end because the insertion portion 2a for inserting the vertical water surface member 1 is formed, but the lower end is closed by the bottom plate 2b. The water device 10 increases in weight by the amount of water introduced into the frame member 2 and the vertical water surface member 1. Accordingly, the weight added to the weight of the water stop device 10 plus the weight of the water is added to the bottom plate 2b, and the force pressing the installation surface (ground) by the bottom plate 2b acts. Then, although it is much lighter, there is no fear that the water stop device 10 will be washed away by the water flow without using a fixture or the like.

また、上記枠材２の内部には、図２等に示すように、縦止水面材１の下端面を受ける面材受け片２ｃが形成されており、その面材受け片２ｃの上側には、縦止水面材１を挟持する小凸条２ｄが、枠材２の幅方向に亘って形成されている。さらに、枠材２内部の略真ん中には、水平中間板２ｅが形成されており、枠材２に求められる強度を確保している。これら面材受け片２ｃ、小凸条２ｄ、水平中間板２ｅは、枠材２の幅方向全域に亘って形成されている必要はなく、部分的に途切れていても構わないものであって、本実施形態では、図４に示すように、上記開口部４の位置には形成されていない。 Further, as shown in FIG. 2 and the like, a surface material receiving piece 2c for receiving the lower end surface of the vertical water surface material 1 is formed inside the frame material 2, and on the upper side of the surface material receiving piece 2c. The small protrusions 2 d that sandwich the vertical water stop material 1 are formed across the width direction of the frame member 2. Further, a horizontal intermediate plate 2e is formed substantially in the middle of the frame member 2 to ensure the strength required for the frame member 2. These face material receiving pieces 2c, small ridges 2d, and horizontal intermediate plate 2e do not need to be formed over the entire width direction of the frame material 2, and may be partially interrupted, In the present embodiment, as shown in FIG. 4, it is not formed at the position of the opening 4.

上記構成の枠材２は、縦止水面材１を保持することから、縦止水面材１の重量を支えるだけの強度が必要となる。また、水害時には、縦止水面材１に加わった水圧により、縦止水面材１が撓まないように保持するだけの強度と、開口部４より導入された水の重量増加分にも耐え得る強度（特に底板２ｂ）も必要となる。さらに、一方の回動連結部２ｆには、縦止水面材１が水圧により後方（他方）に倒れようとする力が加わるため、その際に破損しないだけの十分な強度も必要となる。このように、枠材２は、止水装置１０において、最も強度が求められることから、合成樹脂製のものでも構わないが、アルミ、ステンレス等の金属製のものが好ましい。 Since the frame member 2 having the above configuration holds the vertical water surface material 1, the frame material 2 needs to be strong enough to support the weight of the vertical water surface material 1. Further, at the time of flooding, the water pressure applied to the vertical water surface material 1 can withstand the strength of holding the vertical water surface material 1 so as not to bend and the increased amount of water introduced from the opening 4. Strength (especially the bottom plate 2b) is also required. Further, since the force that causes the vertical water surface material 1 to fall backward (the other) due to the water pressure is applied to the one rotation connecting portion 2f, it is necessary to have sufficient strength not to be damaged at that time. As described above, the frame member 2 may be made of a synthetic resin because the strength is most required in the water stop device 10, but is preferably made of a metal such as aluminum or stainless steel.

図２に示すように、枠材２の前面側の下端部と底板２ｂの前端部が切り欠かれ、この切り欠かれた枠材２の下端前面側から底面前面側に亘って一方の回動連結部２ｆが一体に形成されている。そして、この一方の回動連結部２ｆと、後述する横止水面材３に形成された他方の回動連結部３ａとが、互いに回動可能に連結されている。また、枠材２の両側面には、端板５を取付けるためのビス穴２ｇが形成されており、枠材２の側面に端板５を配置し、ビス穴２ｇにビス５ａをねじ込み固定することによって、枠材２の開口した側面が覆われている。 As shown in FIG. 2, the lower end portion on the front side of the frame member 2 and the front end portion of the bottom plate 2b are notched, and one rotation is performed from the lower end front side to the bottom front side of the notched frame member 2. The connecting portion 2f is integrally formed. And this one rotation connection part 2f and the other rotation connection part 3a formed in the horizontal water surface material 3 mentioned later are connected so that rotation is mutually possible. Further, screw holes 2g for attaching the end plates 5 are formed on both side surfaces of the frame material 2, and the end plates 5 are arranged on the side surfaces of the frame material 2, and screws 5a are screwed into the screw holes 2g and fixed. Thus, the opened side surface of the frame member 2 is covered.

上記枠材２に形成された一方の回動連結部２ｆは、図１、図２に示すように、枠材２の底板２ｂの前端上側に一体に形成された前側が開放する略半円外筒部２０ｆと、この略半円外筒部２０ｆの上端に形成された当止部２１ｆ（他方の回動連結部３ａの略半円筒部３ｂの後端を当止する当止部）と、この当止部２１ｆの先端に形成された後方斜め下側が開放する略半円小筒部２２ｆと、この略半円小筒部２２ｆの後端から枠材２の下端に連なるように形成された前側が開放する収容部２３ｆ（他方の回動連結部３ａの略半円筒部３ｂの厚肉化された前半部３ｃを収容する収容部）とを備えたものである。 As shown in FIG. 1 and FIG. 2, the one rotary connecting portion 2 f formed on the frame member 2 is substantially semicircular outside where the front side formed integrally with the front end of the bottom plate 2 b of the frame member 2 opens. A cylindrical portion 20f, and a stopper 21f formed at the upper end of the substantially semicircular outer cylindrical portion 20f (a stopper for stopping the rear end of the substantially semi-cylindrical portion 3b of the other rotation connecting portion 3a); The semi-cylindrical small cylindrical portion 22f formed at the front end of the stopper 21f and opened obliquely downward from the rear side is formed, and the rear end of the semi-cylindrical small cylindrical portion 22f is connected to the lower end of the frame member 2. And a housing portion 23f (a housing portion that houses the thickened front half portion 3c of the substantially semi-cylindrical portion 3b of the other rotation connecting portion 3a).

これに対して、上記枠材２に連結される横止水面材３は、アルミ、ステンレス等の金属で成形された方形の板体であって、横止水面材３の後端上面側には、図２に示すように、上記枠材２に形成された一方の回動連結部２ｆと互いに回動可能に連結される他方の回動連結部３ａが、横止水面材３の全幅に亘って一体に形成されている。 On the other hand, the lateral water surface material 3 connected to the frame material 2 is a rectangular plate formed of a metal such as aluminum or stainless steel. As shown in FIG. 2, the other rotation connecting portion 3 a that is rotatably connected to one rotation connecting portion 2 f formed on the frame member 2 extends over the entire width of the lateral water stop surface material 3. Are integrally formed.

この他方の回動連結部３ａは、図２に示すように、横止水面材３の後端上面側に一体に形成された上側が開放する略半円筒部３ｂと、この略半円筒部３ｂの後半部の内面から求心方向に突出する突出部３ｃと、この突出部３ｃの先端に一体に形成された丸棒状の回動中心部３０とを備えたものであって、略半円筒部３ｂの前半部３ｄは厚肉化されている。 As shown in FIG. 2, the other rotation connecting portion 3a includes a substantially semi-cylindrical portion 3b that is integrally formed on the upper surface side of the rear end of the lateral water surface member 3 and that is open on the upper side. A projecting part 3c projecting in the centripetal direction from the inner surface of the rear half part of the first part, and a round bar-shaped rotation center part 30 integrally formed at the tip of the projecting part 3c. The first half 3d is thickened.

一方の回動連結部２ｆと他方の回動連結部３ａは、一方の回動連結部２ｆの内側空間（即ち、略半円外筒部２０ｆと当止部２１ｆと略半円小筒部２２ｆによって囲まれる内側空間）に、他方の回動連結部３ａ（即ち、略半円筒部３ｂの厚肉化されていない後半部と突出部３ｃと回動中心部３０）を、一方の回動連結部２ｆのいずれか一端から挿入することによって、互いに回動可能に且つ前後方向に外れないように連結されており、一方の回動連結部２ｆの内側空間から他方の回動連結部３ａを引き抜くと連結が解除されるようになっている。 One rotation connecting portion 2f and the other rotation connecting portion 3a are arranged in an inner space of one rotation connecting portion 2f (that is, a substantially semicircular outer cylindrical portion 20f, a stopper portion 21f, and a substantially semicircular small cylindrical portion 22f. The other rotation connecting portion 3a (that is, the non-thickened rear half portion of the substantially semi-cylindrical portion 3b, the projecting portion 3c, and the rotation center portion 30) is connected to one rotation connection. By being inserted from either one end of the portion 2f, they are connected to each other so as to be able to rotate and not to be disengaged in the front-rear direction, and the other rotating connecting portion 3a is pulled out from the inner space of one rotating connecting portion 2f. And the connection is released.

上記のように、一方の回動連結部２ｆと他方の回動連結部３ａを連結し、回動させて縦止水面材１を真上に９０°起立させた図２の状態では、他方の回動連結部３ａの略半円筒部３ｂの厚肉化されていない後半部が一方の回動連結部２ｆの略半円外筒部２０ｆで受けられ、略半円筒部３ｂの後半部の外面が略半円外筒部２０ｆの内面に回動可能に摺接している。そして、他方の回動連結部３ａの回動中心部３０は一方の回動連結部２ｆの略半円小筒部２２ｆで受けられ、回動中心部３０の外面が略半円小筒部２２ｆの内面に回動可能に摺接している。しかし、他方の回動連結部３ａの略半円筒部３ｂの厚肉化された前半部３ｄは一方の回動連結部２ｆの収容部２３ｆに収容されてなく、また、略半円筒部３ｂの後端も一方の回動連結部２ｆの当止部２１ｆで当止されていない。 As described above, in the state of FIG. 2 in which the one rotation connecting portion 2f and the other rotation connecting portion 3a are connected and rotated so that the vertical water surface material 1 is erected 90 ° directly above, The non-thickened rear half portion of the substantially semi-cylindrical portion 3b of the rotational connecting portion 3a is received by the substantially semicircular outer cylindrical portion 20f of one rotational coupling portion 2f, and the outer surface of the rear half portion of the substantially semi-cylindrical portion 3b Is in sliding contact with the inner surface of the substantially semicircular outer cylindrical portion 20f so as to be rotatable. And the rotation center part 30 of the other rotation connection part 3a is received by the substantially semicircular small cylinder part 22f of one rotation connection part 2f, and the outer surface of the rotation center part 30 is substantially semicircle small cylinder part 22f. It is slidably contacted with the inner surface. However, the thickened front half 3d of the substantially semi-cylindrical part 3b of the other pivotal connecting part 3a is not accommodated in the accommodating part 23f of the one pivotal connecting part 2f. The rear end is not secured by the retaining portion 21f of the one rotation connecting portion 2f.

この図２の状態から縦止水面材１を前方に倒すと、枠材２の一方の回動連結部２ｆが横止水面材３の他方の回動連結部３ａの回動中心部３０の周りに回動し、図３に示すように、他方の回動連結部３ａの略半円筒部３ｂの厚肉化された前半部３ｄが一方の回動連結部２ｆの収容部２３ｆに収容されて、縦止水面材１が横止水面材３の上に重なって折り畳まれる。このように縦止水面材１を横止水面材３の上に折り畳むと、止水装置１０の嵩が低くなり、複数の止水装置を積み重ねてコンパクトに保管したり運搬することが可能となる。 When the vertical water surface member 1 is tilted forward from the state of FIG. 2, one rotation connecting portion 2 f of the frame member 2 is around the rotation center portion 30 of the other rotation connecting portion 3 a of the lateral water blocking surface member 3. As shown in FIG. 3, the thickened front half 3d of the substantially semi-cylindrical portion 3b of the other rotation connecting portion 3a is accommodated in the accommodating portion 23f of the one rotation connecting portion 2f. The vertical water surface material 1 is overlapped on the horizontal water surface material 3 and folded. When the vertical water stop material 1 is folded on the horizontal water stop material 3 in this manner, the bulk of the water stop device 10 is reduced, and a plurality of water stop devices can be stacked and stored compactly or transported. .

上記のような横止水面材３に水圧（下方に押圧する力）が加わると、その水圧は他方の回動連結部３ａから一方の回動連結部２ｆを介して枠材２の底板２ｂに伝わり、止水装置１０をより強く下方に押圧する力が作用する。これに枠材２の内部に導入された水の重量増加分をプラスして、止水装置１０を強固に設置面に押圧するため、より安定的に止水装置１０を設置することができる。 When water pressure (force for pressing downward) is applied to the lateral water surface material 3 as described above, the water pressure is applied to the bottom plate 2b of the frame member 2 from the other rotation connection portion 3a via one rotation connection portion 2f. The force which pushes down the water stop apparatus 10 more strongly acts acts. Since the weight increase of the water introduced into the frame member 2 is added to this and the water stop device 10 is firmly pressed against the installation surface, the water stop device 10 can be installed more stably.

以上のような構成の止水装置１０は、図１に示すように、縦止水面材１の両側に略凹型の縦枠６，６を取付けると共に、縦止水面材１の上端に略凹型の横枠７を取付けて、建物や地下の出入口等の両側にある柱体８，８との間に設置される。水害時には、縦止水面材１の内部にも水が導入されることから、横枠７により中空部を完全に塞いでしまうと空気が抜けず、水が入ってこない。従って、縦止水面材１の上端と横枠７との間には少しの隙間を設けるか、或いは、別途空気抜き孔等を設けることが好ましい。また、縦止水面材１の背面に止水パッキン９を設け、柱体８，８との間の水密性を向上させることが好ましい。図示はしないが、横止水面材３と設置面との間にも、止水パッキン９を設けてもよい。勿論、本発明の設置される場所は、柱体８，８間により形成される出入口等に限られるものではなく、水の浸入を阻止したいありとあらゆる箇所に設置できるものであることは言うまでもない。 As shown in FIG. 1, the water stop device 10 having the above-described configuration attaches substantially concave vertical frames 6 and 6 to both sides of a vertical water stop face material 1 and has a substantially concave shape at the upper end of the vertical water stop face material 1. The horizontal frame 7 is attached and installed between the pillars 8 and 8 on both sides of the building and underground entrance / exit. At the time of water damage, water is also introduced into the vertical water surface material 1, and therefore, if the hollow portion is completely blocked by the horizontal frame 7, air does not escape and water does not enter. Therefore, it is preferable to provide a small gap between the upper end of the vertical water surface material 1 and the horizontal frame 7 or to provide a separate air vent hole or the like. Moreover, it is preferable to provide the water-stopping packing 9 on the back surface of the vertical water-stopping material 1 to improve the watertightness between the column bodies 8 and 8. Although not shown, a water blocking packing 9 may be provided between the lateral water blocking material 3 and the installation surface. Of course, the place where the present invention is installed is not limited to the entrance and the like formed between the column bodies 8 and 8, and it goes without saying that it can be installed at any place where it is desired to prevent water from entering.

本発明の止水装置１０は、設置する場所の大きさに合致する寸法のものを用いればいいものであり、特に限定されるものではないが、運搬性や主に設置される場所の広さ等を考慮すると、概ねその高さが２０〜１００ｃｍ（本実施形態では５０ｃｍ）、幅が５０〜２５０ｃｍ（本実施形態では１００ｃｍ）程度のものが好適に用いられる。 The water stop device 10 of the present invention may be of a size that matches the size of the place where it is installed, and is not particularly limited. In consideration of the above, those having a height of approximately 20 to 100 cm (50 cm in the present embodiment) and a width of approximately 50 to 250 cm (100 cm in the present embodiment) are preferably used.

上記の説明から明らかなように、本発明の止水装置１０は、水が浸入する枠材２の前面側の下部に、内部に水を導入する開口部４が形成されているため、水害時に押し寄せた水は該開口部４より止水装置１０の内部（枠材２内部及び縦止水面材１内部）に導入されて、導入された水の重量分だけ止水装置１０の重量が増加する。従って、設置面に対して止水装置１０を鉛直方向に押し付ける力が作用し、安定感が増して水密性も向上することから、別途固定具等を用いなくとも、流される心配なくして止水装置１０を設置することができる。このように本発明は、従来のような注入口より水を注入する工程等を省くことができ、単に建物や地下の出入口等の前に装置を載置するという容易な作業で浸水を確実に防ぐことができるため、短時間の内に多くの被害をもたらす昨今の水害にも十分に対応することができ、また、特殊な吸水材料を必要としないため、余計なコストがかからず、吸水性能を特殊な吸水材料に依存することがないため、水が押し寄せた初期の段階から、安定的に浸水を防ぐことができる。 As is clear from the above description, the water stop device 10 of the present invention has an opening 4 for introducing water into the lower part on the front side of the frame material 2 into which water enters. The pushed water is introduced from the opening 4 into the water stop device 10 (inside the frame member 2 and inside the vertical water surface material 1), and the weight of the water stop device 10 increases by the amount of the introduced water. . Accordingly, a force that presses the water stop device 10 in the vertical direction acts on the installation surface, so that the sense of stability is increased and the water tightness is also improved. The device 10 can be installed. As described above, the present invention can eliminate the step of injecting water from the conventional inlet, and can ensure the inundation by simply placing the device in front of the building or underground entrance / exit. Because it can prevent, it can sufficiently cope with recent water damage that causes a lot of damage within a short time, and it does not require special water absorption material, so there is no extra cost and water absorption Since the performance does not depend on a special water-absorbing material, it is possible to stably prevent flooding from the initial stage when water has rushed.

図５は本発明の他の実施形態に係る止水装置を示す斜視図、図６は図５のＢ−Ｂ線断面図、図７は同止水装置の開口部を別の箇所に形成した形態を示す概略部分断面図である。 5 is a perspective view showing a water stop device according to another embodiment of the present invention, FIG. 6 is a cross-sectional view taken along line BB of FIG. 5, and FIG. 7 is an opening of the water stop device formed at another location. It is a general | schematic fragmentary sectional view which shows a form.

本実施形態の止水装置１０は、縦止水面材１と枠材２を備えたものであり、前述した図１〜図４に示す止水装置１０とは異なり、横止水面材３は用いずに一方から他方への水の浸入を阻止するものである。 The water stop device 10 of the present embodiment includes the vertical water stop surface material 1 and the frame material 2, and unlike the water stop device 10 shown in FIGS. 1 to 4 described above, the horizontal water stop surface material 3 is used. Without blocking water from one to the other.

この縦止水面材１は、前述した図１〜図４に示す止水装置１０の縦止水面材１と同様に、１対の表面材の間に、複数の隔壁部（横の隔壁部、縦の隔壁部、斜めの隔壁部）が形成された、鉛直方向に貫通する多数の中空部が形成されたものであって、本実施形態の止水装置１０は、前述した図１〜図４に示す止水装置１０よりも小型のものであることから、図１に示す縦止水面材１よりも中空部の数が少なく、幅狭となっている。 Like the vertical water stop material 1 of the water stop device 10 shown in FIGS. 1 to 4 described above, the vertical water stop material 1 has a plurality of partition walls (horizontal partition walls, A plurality of hollow portions penetrating in the vertical direction in which vertical partition walls and oblique partition walls are formed, and the water stop device 10 of the present embodiment is the above-described FIGS. Therefore, the number of hollow portions is smaller than that of the vertical water stop face material 1 shown in FIG. 1, and the width is narrower.

また、図６に示すように、枠材２も前述した図１〜図４に示す実施形態と同様、その上端部に、縦止水面材１の下端部を挿入する凹空状の挿入部２ａが形成されると共に、下端は底板２ｂによって閉口した中空筒状のものであって、図５に示すように、その前面側の下部には、２つの開口部４が形成されている。この開口部４も、枠材２の前面側を方形状に切り欠くことにより形成されたものであり、これら３つの開口部４は、枠材２内部で全て連通しており、挿入部２ａとも連通している。 Moreover, as shown in FIG. 6, the frame material 2 is also the hollow insertion part 2a which inserts the lower end part of the vertical water surface material 1 in the upper end part similarly to embodiment shown in FIGS. 1-4 mentioned above. Is formed, and the lower end has a hollow cylindrical shape closed by the bottom plate 2b. As shown in FIG. 5, two openings 4 are formed in the lower part on the front side. This opening 4 is also formed by cutting out the front side of the frame member 2 into a square shape, and these three openings 4 are all in communication within the frame member 2, and are also connected to the insertion portion 2 a. Communicate.

同様に、上記枠材２の内部には、縦止水面材１の下端面を受ける面材受け片２ｃが形成されており、その面材受け片２ｃの上側には、縦止水面材１を挟持する小凸条２ｄが、枠材２の幅方向に亘って形成されている。本実施形態の止水装置１０は、水を導入する開口部４が底板２ｂの真上に形成されていることから、前述した図１〜図４に示す実施形態とは異なり、枠材２の強度を確保する水平中間板２ｅは形成されていない。この止水装置１０は、前述した止水装置１０よりも小型のものであることから、強度的に問題が生じることは少ないものであるが、所々で左側の面材受け片２ｃと右側の面材受け片２ｃを連結して強度を確保してもよく、或いは、図７に示すように、面材受け片２ｃを形成せずに、縦止水面材１の下端面を底板２ｂの上に載置することにより、枠材２の強度を確保してもよい。この際、単に枠材２の挿入部２ａに上記縦止水面材１を挿入するだけでは、開口部４が殆ど塞がれて水が導入されなくなるため、縦止水面材１の前面側の下部に、水を導入する連通孔１ａを設ける必要がある。 Similarly, a surface material receiving piece 2c for receiving the lower end surface of the vertical water stop surface material 1 is formed inside the frame material 2, and the vertical water stop surface material 1 is provided above the surface material receiving piece 2c. A small protruding line 2 d to be sandwiched is formed across the width direction of the frame member 2. Unlike the embodiment shown in FIGS. 1 to 4 described above, the water stop device 10 of the present embodiment has an opening 4 for introducing water formed directly above the bottom plate 2b. The horizontal intermediate plate 2e that ensures the strength is not formed. Since the water stop device 10 is smaller than the water stop device 10 described above, it is less likely to cause a problem in terms of strength. The material receiving piece 2c may be connected to ensure strength, or, as shown in FIG. 7, the bottom end surface of the vertical water face material 1 is placed on the bottom plate 2b without forming the face material receiving piece 2c. You may ensure the intensity | strength of the frame material 2 by mounting. At this time, simply by inserting the vertical water surface material 1 into the insertion part 2a of the frame material 2, the opening 4 is almost blocked and water is not introduced. It is necessary to provide a communication hole 1a for introducing water.

上記のように、本実施形態の止水装置１０は横止水面材３を用いないものであるため、枠材２には、前述した実施形態のような、一方の回動連結部２ｆは設けられていない。そのため、設置面に対して下方へ押し付ける力は若干劣ることになるが、軽量であるため運搬性に優れ、例えば柱体８等の立設物に立て掛けるようにして用いれば一切の問題は生じない。
本実施形態の止水装置１０のその他の構成は、前述した図１〜図４に示す実施形態の止水装置１０と同様であるので、同一部材に同一符号を附して説明を省略する。 As described above, since the water stop device 10 of the present embodiment does not use the horizontal water stop surface material 3, the frame member 2 is provided with one rotating connection portion 2f as in the above-described embodiment. It is not done. For this reason, the force pressing downward on the installation surface is slightly inferior, but it is lightweight and has excellent transportability. For example, if it is used leaning against a standing object such as the column 8, no problems will occur. .
Since the other structure of the water stop apparatus 10 of this embodiment is the same as that of the water stop apparatus 10 of embodiment shown in FIGS. 1-4 mentioned above, the same code | symbol is attached | subjected to the same member and description is abbreviate | omitted.

図８は本発明の更に他の実施形態に係る止水装置を示す斜視図である。 FIG. 8 is a perspective view showing a water stop device according to still another embodiment of the present invention.

この実施形態の止水装置１０も、縦止水面材１と枠材２を備えたものであり、縦止水面材１は、前述した図１〜図４に示す実施形態のものと同様に、１対の表面材の間に、複数の隔壁部（横の隔壁部、縦の隔壁部、斜めの隔壁部）からなる多数の中空部が形成されたものを用いているが、該実施形態とは異なり、中空部が水平方向に貫通するようにして用いられる（つまり９０°回転させて用いている）。 The water stop device 10 of this embodiment is also provided with the vertical water stop material 1 and the frame material 2, and the vertical water stop material 1 is similar to that of the embodiment shown in FIGS. A material in which a large number of hollow portions made of a plurality of partition walls (horizontal partition walls, vertical partition walls, diagonal partition walls) are formed between a pair of surface materials is used. In contrast, the hollow portion is used so as to penetrate in the horizontal direction (that is, rotated by 90 °).

上記縦止水面材１を保持する枠材２は、図８に示すように、底板２ｂに対して天板の面積が小さい台形状をしたものであり、その内部は中空状となっている。このように枠材２を台形状にすることによって、枠材２が倒れ難くなるのは勿論のこと、水害時に枠材２に水圧が加わると、下方へ押圧する力が、方形状の枠材２に比較すると強く作用することから、止水装置１０がより安定的に設置されるようになる。 As shown in FIG. 8, the frame member 2 that holds the vertical water stop material 1 has a trapezoidal shape in which the area of the top plate is smaller than the bottom plate 2b, and the inside thereof is hollow. By making the frame material 2 trapezoidal in this way, the frame material 2 is not easily toppled, and when water pressure is applied to the frame material 2 in the event of a flood, the downward pressing force is applied to the square frame material. Since it acts strongly compared to 2, the water stop device 10 is more stably installed.

また、枠材２内側面の上端部から下端部にかけて、上記縦止水面材１を挿入する凹型の挿入部２ａが鉛直方向に延びるように形成されている。そして、枠材２の前面側の下部には、方形状の開口部４が形成されており、枠材２の内部に押し寄せた水を導入できるようになっている。このとき、縦止水面材１を保持する挿入部２ａに貫通孔を設けていると、開口部４より導入された水が、貫通孔を経由して縦止水面材１にも流入するようにできる。
本実施形態の止水装置１０のその他の構成は、前述した図１〜図４に示す実施形態の止水装置１０と同様であるので、同一部材に同一符号を附して説明を省略する。 Moreover, the concave insertion part 2a which inserts the said vertical water stop surface material 1 is formed so that it may extend in a perpendicular direction from the upper end part of a frame material 2 inner surface to a lower end part. A rectangular opening 4 is formed in the lower part on the front side of the frame member 2 so that water rushed into the frame member 2 can be introduced. At this time, if a through hole is provided in the insertion portion 2a that holds the vertical water surface material 1, water introduced from the opening 4 flows into the vertical water surface material 1 through the through hole. it can.
Since the other structure of the water stop apparatus 10 of this embodiment is the same as that of the water stop apparatus 10 of embodiment shown in FIGS. 1-4 mentioned above, the same code | symbol is attached | subjected to the same member and description is abbreviate | omitted.

この止水装置１０は、縦止水面材１と一対の枠材２，２を備えていることから、運搬性等は多少犠牲になるが、内部に導入する水の容量が非常に多いため、止水装置１０をより安定的に設置することができ、例えば建物や地下の出入口等だけでなく、防水扉などとしても用いることができる。 Since the water stop device 10 includes the vertical water stop material 1 and the pair of frame members 2 and 2, the transportability and the like are somewhat sacrificed, but the capacity of water introduced into the interior is very large. The water stop device 10 can be more stably installed. For example, the water stop device 10 can be used not only as a building or underground entrance but also as a waterproof door.

図９は本発明の更に他の実施形態に係る止水装置を示す斜視図である。 FIG. 9 is a perspective view showing a water stop device according to still another embodiment of the present invention.

本実施形態の止水装置１０は、縦止水面材１のみを備えたものであり、前述したような枠材２、横止水面材３は用いない態様である。 The water stop device 10 according to the present embodiment includes only the vertical water stop material 1 and does not use the frame material 2 and the horizontal water stop material 3 as described above.

この縦止水面材１は、前述した図８に示す実施形態と同様に、１対の表面材の間に、複数の隔壁部（横の隔壁部、縦の隔壁部、斜めの隔壁部）により形成された多数の中空部が、水平方向に貫通するようにして用いられるものである。上記のように、本実施形態では、枠材２等を用いないため、枠材２に形成された水を導入する開口部４も存在しないが、縦止水面材１には多数の中空部が形成されているため、その中空部が開口部４となり、そこから止水装置１０の内部に水が導入されるようになっている。勿論、この側面の開口部４の他にも、縦止水面材１の前面側の下部に、別途開口部４を形成してもよいことは言うまでもない。
本実施形態の止水装置１０のその他の構成は、前述した図１〜図４に示す実施形態の止水装置１０と同様であるので、同一部材に同一符号を附して説明を省略する。 As in the embodiment shown in FIG. 8 described above, the vertical water surface material 1 includes a plurality of partition walls (horizontal partition walls, vertical partition walls, diagonal partition walls) between a pair of surface materials. A large number of formed hollow portions are used so as to penetrate in the horizontal direction. As described above, in this embodiment, since the frame member 2 or the like is not used, there is no opening 4 for introducing water formed in the frame member 2, but the vertical water surface member 1 has a large number of hollow portions. Since it is formed, the hollow portion becomes the opening 4, and water is introduced into the water stop device 10 from there. Of course, it is needless to say that the opening 4 may be separately formed in the lower part on the front side of the longitudinal water blocking material 1 in addition to the opening 4 on the side surface.
Since the other structure of the water stop apparatus 10 of this embodiment is the same as that of the water stop apparatus 10 of embodiment shown in FIGS. 1-4 mentioned above, the same code | symbol is attached | subjected to the same member and description is abbreviate | omitted.

上記実施形態のように、本発明の止水装置１０は、縦止水面材１のみからでも構築することができ、このような縦止水面材１からなる止水装置１０は、非常に簡易（柱体８，８等に立て掛けるだけ）に設置することができる。また、水を導入する開口部４は、前述した実施形態のように装置の前面側だけでなく、側面側に形成しても内部に水を導入することができる。 Like the said embodiment, the water stop apparatus 10 of this invention can be constructed | assembled only from the vertical water surface material 1, and the water stop apparatus 10 which consists of such a vertical water surface material 1 is very simple ( It can be installed on the column body 8, 8 or the like. Moreover, even if the opening 4 for introducing water is formed not only on the front side of the apparatus but also on the side surface as in the above-described embodiment, water can be introduced into the inside.

図１０は本発明の更に他の実施形態に係る止水装置を示すものであって、止水装置同士を連結した状態の斜視図である。 FIG. 10 shows a water stop device according to still another embodiment of the present invention, and is a perspective view of a state where the water stop devices are connected to each other.

図１０は、複数の止水装置１０を左右に連結する態様を示すものであって、より広範囲の浸水を防止する態様である。この縦止水面材１も前述した図９に示す実施形態と同様に、縦止水面材１の中空部が水平方向に貫通するようにして用いる。 FIG. 10 shows an aspect in which a plurality of water stop devices 10 are connected to the left and right, and is an aspect that prevents water in a wider range. Similarly to the embodiment shown in FIG. 9 described above, the vertical water stop material 1 is also used so that the hollow portion of the vertical water stop material 1 penetrates in the horizontal direction.

本実施形態の縦止水面材１は、枠材２の挿入部２ａに挿入されて保持されており、縦止水面材１の左右両側面には、略コ字状の縦枠６が取付けられている。このような止水装置１０を左右に連結するには、一方の止水装置１０の側面（縦枠６）を、他方の止水装置１０の側面（縦枠６）に突き合わせて、連結固定具１１により固定する。この連結固定具１１は、止水装置１０，１０を左右に簡単且つ確実に連結できるものであればどのような形態のものでもよい。そして、図１０に示すように、相対面する止水装置１０，１０に取付けられた縦枠６，６の間には、止水性を向上させるための止水パッキン９が介在されており、連結箇所からの浸水を防止している。 The vertical water stop material 1 of this embodiment is inserted and held in the insertion portion 2a of the frame material 2, and substantially U-shaped vertical frames 6 are attached to the left and right side surfaces of the vertical water stop material 1. ing. In order to connect such a water stop device 10 to the left and right, the side surface (vertical frame 6) of one water stop device 10 is abutted against the side surface (vertical frame 6) of the other water stop device 10, and a connecting fixture 11 to fix. The connecting fixture 11 may have any form as long as it can easily and reliably connect the water stop devices 10 and 10 to the left and right. And as shown in FIG. 10, between the vertical frames 6 and 6 attached to the water stop apparatus 10 and 10 which face each other, the water stop packing 9 for improving water stop is interposed, and it connects. Prevents water from entering the area.

この止水装置１０も、上記のように、縦止水面材１の中空部が水平方向に貫通している。これを換言すれば、枠材２と縦止水面材１の中空部が連通していないということであり、前述した実施形態のように、枠材２の前面側下部に開口部４を形成しても、枠材２の内部にのみ水が導入されるだけで、縦止水面材１の中空部には水が流入してこない。そこで本実施形態では、図１０に示すように、縦枠６の前面側下部に複数の開口部４を形成し、縦止水面材１の側端面と対向する縦枠６との間に少しの隙間を設けて、縦枠６に形成された開口部４より導入された水が、縦止水面材１の中空部にも流入するようにしている。また、図示はしないが、縦枠６の側面下部（図１０でいう右側の止水装置１０の右側面に取付けられている縦枠６の側面下部、及び、左側の止水装置１０の左側面に取付けられている縦枠６の側面下部）に、方形状又は円形状の孔を穿孔して開口部４を形成することも好ましい。このように縦枠６の下部に開口部４を形成すると、縦止水面材１の中空部が水平方向に貫通していることから、縦枠６の前面側下部に上記のような開口部４を形成しなくとも、縦止水面材１の内部に水を導入することができるようになる。
本実施形態の止水装置１０のその他の構成は、前述した図１〜図４、図９に示す実施形態の止水装置１０と同様であるので、同一部材に同一符号を附して説明を省略する。 As described above, the water blocking device 10 also has the hollow portion of the vertical water blocking material 1 penetrating in the horizontal direction. In other words, the hollow part of the frame member 2 and the longitudinal water surface member 1 is not in communication, and the opening 4 is formed in the lower part on the front side of the frame member 2 as in the above-described embodiment. However, water is only introduced into the frame member 2, and water does not flow into the hollow portion of the vertical water surface member 1. Therefore, in the present embodiment, as shown in FIG. 10, a plurality of openings 4 are formed in the lower part on the front side of the vertical frame 6, and a little between the vertical frame 6 facing the side end surface of the vertical waterstop material 1. A gap is provided so that water introduced from the opening 4 formed in the vertical frame 6 also flows into the hollow portion of the vertical waterstop 1. Moreover, although not shown in figure, the lower part of the side surface of the vertical frame 6 (the lower part of the side surface of the vertical frame 6 attached to the right side surface of the water stop device 10 on the right side in FIG. 10 and the left side surface of the water stop device 10 on the left side) It is also preferable to form an opening 4 by drilling a square or circular hole in the lower part of the side surface of the vertical frame 6 attached to the vertical frame 6. When the opening 4 is formed in the lower part of the vertical frame 6 as described above, the hollow part of the vertical water surface material 1 penetrates in the horizontal direction. Even if not formed, water can be introduced into the longitudinal water surface member 1.
Since the other structure of the water stop apparatus 10 of this embodiment is the same as that of the water stop apparatus 10 of embodiment shown in FIGS. 1-4, FIG. 9 mentioned above, the same code | symbol is attached | subjected and demonstrated to the same member. Omitted.

以上のように、止水装置１０，１０同士を連結する一例（図９の連結態様）を説明してきたが、例えば図１〜図８に示す止水装置１０においても、同様に連結することができる。このように、止水装置１０を複数連結することにより、水の浸入を阻止する箇所が、広範囲に亘ったとしても対応することができる。 As mentioned above, although the example (connection aspect of FIG. 9) which connects the water stop apparatuses 10 and 10 has been demonstrated, it can connect similarly also in the water stop apparatus 10 shown, for example in FIGS. it can. In this way, by connecting a plurality of water stop devices 10, it is possible to cope with a wide range of locations where water entry is prevented.

図１１は本発明の更に他の実施形態に係る止水装置を示す斜視図である。 FIG. 11 is a perspective view showing a water stop device according to still another embodiment of the present invention.

本実施形態の止水装置１０は、図１１に示すように、縦止水面材１と横止水面材３とを備えた略Ｌ字型の装置であって、縦止水面材１には、強度を確保するため必要十分な厚みを有する平板が用いられている。また、横止水面材３には、前述した図１に示す縦止水面材１の中空部が、一方（水の浸入側）に向くように配置したものを用いている。従って、横止水面材３の中空部が開口部４としての役割を果たし、別途開口部４を形成しなくとも、中空部から横止水面材３の内部に水が導入されて、横止水面材３を下方へ押圧する力が作用する。
なお、本実施形態では、複数の隔壁部（横の隔壁部、縦の隔壁部、斜めの隔壁部）が形成されたものを横止水面材３としているが、隔壁部が形成されていない単なる角筒を複数連結したものを横止水面材３とすることもできる。また、枠材２を省略しているが、縦止水面材１の挿入部２ａ、及び、横止水面材３の挿入部２ａが形成された枠材２により、縦止水面材１と横止水面材３を連結しても構わない。
本実施形態の止水装置１０のその他の構成は、前述した図１〜図４に示す実施形態の止水装置１０と同様であるので、同一部材に同一符号を附して説明を省略する。 As shown in FIG. 11, the water stop device 10 of the present embodiment is a substantially L-shaped device provided with a vertical water stop material 1 and a horizontal water stop material 3. A flat plate having a necessary and sufficient thickness for securing strength is used. Further, as the lateral water stop material 3, one in which the hollow portion of the vertical water stop material 1 shown in FIG. 1 described above is directed to one side (water ingress side) is used. Accordingly, the hollow portion of the lateral water surface material 3 serves as the opening 4, and water is introduced into the lateral water surface material 3 from the hollow portion without forming the separate opening 4, and the lateral water surface The force which presses the material 3 below acts.
In the present embodiment, the lateral water stop face material 3 is formed with a plurality of partition walls (horizontal partition walls, vertical partition walls, and diagonal partition walls), but the partition walls are simply not formed. A structure in which a plurality of rectangular tubes are connected to each other can be used as the lateral water surface material 3. Although the frame material 2 is omitted, the vertical water surface material 1 and the horizontal stopper are formed by the frame material 2 in which the insertion portion 2a of the vertical water surface material 1 and the insertion portion 2a of the horizontal water surface material 3 are formed. The water surface material 3 may be connected.
Since the other structure of the water stop apparatus 10 of this embodiment is the same as that of the water stop apparatus 10 of embodiment shown in FIGS. 1-4 mentioned above, the same code | symbol is attached | subjected to the same member and description is abbreviate | omitted.

図１２は本発明の更に他の実施形態に係る止水装置を示す斜視図である。 FIG. 12 is a perspective view showing a water stop device according to still another embodiment of the present invention.

本実施形態の止水装置１０も、縦止水面材１と横止水面材３とを備えた略Ｌ字型の装置であって、縦止水面材１には、前述した図１１に示す縦止水面材１と同様に、強度を確保するため必要十分な厚みを有する平板が用いられている。また、横止水面材３には、横の隔壁部、縦の隔壁部、斜めの隔壁部によって、中空部が１つだけ形成された方形状の角筒が用いられている。この横止水面材３も、隔壁部が形成されていない単なる角筒を横止水面材３として用いてもよい。 The water stop device 10 of the present embodiment is also a substantially L-shaped device provided with the vertical water stop material 1 and the horizontal water stop material 3, and the vertical water stop material 1 includes the vertical water stop material 1 shown in FIG. Similar to the water-stop face material 1, a flat plate having a necessary and sufficient thickness is used to ensure strength. Further, the lateral water blocking member 3 is a rectangular square tube in which only one hollow portion is formed by a horizontal partition wall portion, a vertical partition wall portion, and an oblique partition wall portion. As this lateral water surface material 3, a simple square tube in which no partition wall is formed may be used as the lateral water surface material 3.

本実施形態のように、横止水面材３が２本の角筒から形成されていると、止水装置１０の重量が非常に軽量なものとなり、さらに運搬性に優れるという利点がある。しかしながら、縦止水面材１と横止水面材３の連結している面積が小さいため、縦止水面材１と横止水面材３の連結強度が弱く、一方（前方）から水圧が加わると、連結が外れて縦止水面材１が他方（後方）に倒れてしまう恐れも生じる。そこで、図１２に示すように、縦止水面材１と横止水面材３を引張具１２により連結することによって、縦止水面材１の倒れを防止している。
本実施形態の止水装置１０のその他の構成は、前述した図１〜図４に示す実施形態の止水装置１０と同様であるので、同一部材に同一符号を附して説明を省略する。 If the horizontal water stop face material 3 is formed of two rectangular tubes as in this embodiment, the weight of the water stop device 10 is very light, and there is an advantage that it is excellent in transportability. However, since the area where the vertical water surface material 1 and the horizontal water surface material 3 are connected is small, the connection strength between the vertical water surface material 1 and the horizontal water surface material 3 is weak, and when water pressure is applied from one (front), There is also a risk that the longitudinal water surface material 1 falls to the other side (rear side) due to disconnection. Therefore, as shown in FIG. 12, the vertical water surface material 1 and the horizontal water surface material 3 are connected by a tension tool 12 to prevent the vertical water surface material 1 from falling.
Since the other structure of the water stop apparatus 10 of this embodiment is the same as that of the water stop apparatus 10 of embodiment shown in FIGS. 1-4 mentioned above, the same code | symbol is attached | subjected to the same member and description is abbreviate | omitted.

図１３は本発明の更に他の実施形態に係る止水装置を示す斜視図である。 FIG. 13 is a perspective view showing a water stop device according to still another embodiment of the present invention.

図１３に示す止水装置１０は、方形状の横止水面材３の略中間地点から縦止水面材１が上方に立設された逆Ｔ字型をしたものであり、横止水面材３の前面側に、止水装置１０の内部に水を導入するための開口部４が複数形成されたものである。 The water stop device 10 shown in FIG. 13 has an inverted T-shape in which the vertical water stop material 1 is erected upward from a substantially middle point of the rectangular horizontal water stop material 3. A plurality of openings 4 for introducing water into the water stop device 10 are formed on the front side.

このような逆Ｔ字型の止水装置１０は、安定して設置することができ、水圧によって倒れてしまう心配が皆無に等しくなる。
本実施形態の止水装置１０のその他の構成は、前述した図１〜図４に示す実施形態の止水装置１０と同様であるので、同一部材に同一符号を附して説明を省略する。 Such an inverted T-shaped water stop device 10 can be installed stably, and there is no fear of falling down due to water pressure.
Since the other structure of the water stop apparatus 10 of this embodiment is the same as that of the water stop apparatus 10 of embodiment shown in FIGS. 1-4 mentioned above, the same code | symbol is attached | subjected to the same member and description is abbreviate | omitted.

図１４は本発明の更に他の実施形態に係る止水装置を示す斜視図である。 FIG. 14 is a perspective view showing a water stop device according to still another embodiment of the present invention.

本実施形態の止水装置１０は、中空状の方形の筐体であって、前面側下部に開口部４が形成されている。この止水装置１０は、一つあたりの体積が小さいため、図１４に示すように、左右に連結するだけでなく、図示はしないが、上下にも連結することで遮水壁を構築していくことも可能となる。
本実施形態の止水装置１０のその他の構成は、前述した図１〜図４に示す実施形態の止水装置１０と同様であるので、同一部材に同一符号を附して説明を省略する。 The water stop device 10 of the present embodiment is a hollow rectangular housing, and an opening 4 is formed in the lower part on the front side. Since the water stop device 10 has a small volume per unit, as shown in FIG. 14, not only is it connected to the left and right, but it is not shown, but it is also connected to the upper and lower sides to construct a water shielding wall. It is also possible to go.
Since the other structure of the water stop apparatus 10 of this embodiment is the same as that of the water stop apparatus 10 of embodiment shown in FIGS. 1-4 mentioned above, the same code | symbol is attached | subjected to the same member and description is abbreviate | omitted.

以上、本発明の種々の態様を詳述してきたが、止水装置１０の水の浸入側に開口部４が形成されているものであれば、本発明の技術的範囲に含まれるものであって、前述した図１〜図１４の実施形態に限定されるものではない。例えば、図１に示す横止水面材３が用いられる態様において、図８〜図１０に示す縦止水面材１の中空部を水平方向に貫通するようにして用いるなど、種々の設計変更を許容し得るものである。 As described above, various aspects of the present invention have been described in detail. However, as long as the opening 4 is formed on the water ingress side of the water stop device 10, it is included in the technical scope of the present invention. Thus, the present invention is not limited to the embodiment shown in FIGS. For example, in the aspect in which the transverse water face material 3 shown in FIG. 1 is used, various design changes are allowed, such as using the hollow part of the vertical water face material 1 shown in FIGS.
