Description

この発明は、例えば建築物の出入口、地下街の出入口などに設置される防水扉に係り、特に、防水扉の材質をＦＲＰで構成すると共に防水扉を出入口の床面に形成した床溝で支持するようにして、防水扉の軽量化と水密性を更に高める床支持方式防水扉構造に関するものである。   The present invention relates to a waterproof door installed at, for example, an entrance / exit of a building, an entrance / exit of an underground mall, and the like. In particular, the waterproof door is made of FRP and supported by a floor groove formed on the floor surface of the entrance / exit. Thus, the present invention relates to a floor-supporting waterproof door structure that further increases the weight and water tightness of the waterproof door.

近年異常気象に伴う局部的な集中豪雨が発生したり、又都市部の道路の整備により、雨水が急速に道路側溝に流入し、その氾濫水が低地部や地下室、地下駐車場地下街に流入する異常事態が頻発している。また河川の整備は行われているが、一部においては、洪水が発生し、その氾濫水が上記の場所に集中し、また同じような事態が発生している。このような事態を防ぐために、建築物の出入口、地下街の出入口にいろいろな防水扉が設置されている。
その製品を大別すると
１）機械式、電動式、エアー式、水圧式
防水扉は常時その位置に設置され、その位置で機械的に作動する。
２）手動式
人が防水扉を所定のところより持ち運び、取付位置に設置する。 In recent years, localized torrential rain due to abnormal weather has occurred, and due to urban road construction, rainwater rapidly flows into the road ditch, and the flood water flows into the lowland, basement, and underground parking lot underground Abnormal situations are frequent. Rivers are being developed, but in some areas floods occur, and the flood water is concentrated in the above locations, and the same situation occurs. To prevent this situation, various waterproof doors are installed at the entrances and exits of buildings and underground malls.
The products can be broadly classified as follows: 1) Mechanical, electric, pneumatic and hydraulic waterproof doors are always installed at that position and mechanically operated at that position.
2) Manual type A person carries the waterproof door from a predetermined location and installs it at the installation position.

ところで、前記の手動式については、次のような課題がある。
１）製品重量について
既存の手動式製品はステンレス製やアルミ製により作られている。出願人により市場リサーチを行った際、現在使用されているユーザーのほとんどの意見として重量が非常に重すぎるということであった。防水扉を操作する人（管理人）は多くのビル等においてその年齢が高く、その負担は考えている以上に大きいということである。
２）荷重支持方式について
通常手動式と呼ばれているものは、防水扉１０１の左右両端側を左右の壁の側面に形成された壁溝１０２の中に挿入して水圧がかかった時、左右の壁溝１０２で防水扉１０１を支える方式をとっている（図７（Ａ）参照）。
通常の防水扉は高さ５００ｍｍ位が標準となっている。このため、入口開口寸法が大きくなれば、当然防水扉の剛性を大きくしなければならず、また重量も重くなってくる。つまり、扉を両側の壁の側面の壁溝で支持する両端単純支持は、開口寸法の横方向の長さに比例して横向きのたわみが大きくなり、これを防ぐためには防水扉の剛性を大きくする必要があり、防水扉の厚みは大きくなり、その結果、重量も重くなる。
３）水密性について
防水扉１０１の目的はもちろん洪水等による水を止水することにある。既存の製品はステンレスやアルミで製作されており、その本体にゴム１０３を取り付け締付金具１０４により防水扉本体（つまりゴム）を溝面に押し付けてゴム１０３を変形させることにより止水している（図７（Ｂ）参照）。
図７（Ｂ）において締付金具１０４を回転させることにより、防水扉１０１及びゴム１０３が埋込枠１０５に押し付けられ、この時ゴム１０３が圧縮されて、止水部を構成する。
しかしながら防水扉が曲がっていたり、埋込枠が曲がっていると、ゴムが圧縮されても完全な止水部が構成できなくなり、部分的にすきまが生じる。当然この部分より水漏れが発生する。
これは、防水扉の材質がステンレスやアルミであり、溶接構造となっているので、溶接歪が発生し、平面度をだすのがむつかしいからである。さらに防水扉の剛性が大きいので、手で締付金具を押し付けるぐらいの力では、防水扉は変形せず、結局完全な止水部が構成されないからである。 By the way, the above-mentioned manual type has the following problems.
1) Product weight Existing manual products are made of stainless steel or aluminum. When conducting market research by the applicant, the weight of most users currently in use was too heavy. The person (administrator) who operates the waterproof door is older in many buildings and the burden is larger than expected.
2) About the load support method What is usually called the manual type is that when the right and left ends of the waterproof door 101 are inserted into the wall grooves 102 formed on the side surfaces of the left and right walls and water pressure is applied, The wall groove 102 supports the waterproof door 101 (see FIG. 7A).
Standard waterproof doors are about 500mm in height. For this reason, if the entrance opening size is increased, the rigidity of the waterproof door must be increased, and the weight is also increased. In other words, the simple support at both ends, which supports the door with the wall grooves on the sides of the walls on both sides, increases the lateral deflection in proportion to the lateral length of the opening dimension. To prevent this, the rigidity of the waterproof door is increased. The thickness of the waterproof door increases, and as a result, the weight also increases.
3) Water-tightness The purpose of the waterproof door 101 is to stop water from flooding. The existing products are made of stainless steel or aluminum. The rubber 103 is attached to the main body, and the waterproof door main body (that is, rubber) is pressed against the groove surface by the fastening metal fitting 104, and the rubber 103 is deformed to stop the water. (See FIG. 7B).
In FIG. 7B, by rotating the fastening metal fitting 104, the waterproof door 101 and the rubber 103 are pressed against the embedding frame 105, and at this time, the rubber 103 is compressed to constitute a water stop portion.
However, if the waterproof door is bent or the embedded frame is bent, even if the rubber is compressed, a complete water stop portion cannot be formed, and a gap is partially generated. Naturally, water leaks from this part.
This is because the waterproof door is made of stainless steel or aluminum and has a welded structure, so that welding distortion occurs and it is difficult to obtain flatness. Furthermore, since the waterproof door has a high rigidity, the waterproof door is not deformed by a force of pressing the fastening bracket by hand, and a complete water stop portion is not formed after all.

この発明は、上記のような課題に鑑み、その課題を解決すべく創案されたものであって、その目的とするところは、防水扉の材質をＦＲＰで構成すると共に防水扉を出入口の床面に形成した床溝で支持することにより、防水扉の軽量化と水密性を更に高めることのできる床支持方式防水扉構造を提供することにある。   The present invention has been made in view of the above problems, and has been devised to solve the problems.

以上の記載より明らかなように、この発明に係るによれば、防水扉の材質をＦＲＰ製にしたので、防水扉の軽量化を図ることができ、防水扉の設置にかかわる作業員の負担を軽減することができる。また、従来の金属製に比べて可塑性が高いので、防水扉と床溝や側溝との水密性を高めて止水機能を高めることができる。これに加えて、防水扉の高さは例えば５００ｍｍが標準であり、このような防水扉を下部で支持する片持梁構造であるので、防水扉の両側端を支える両端単純支持に比較すると、そのたわみが非常に小さくなり、さらに、防水扉が設置される出入口の開口幅寸法が変化しても、そのたわみの大きさは変わらない。つまり、防水扉の幅（入口開口寸法）が変わっても防水扉に加わる水圧による曲げモーメントは、変化しないので防水扉の厚みを変える必要はない。従って、防水扉の重量を結果的に軽くすることができる。   As is clear from the above description, according to the present invention, since the waterproof door is made of FRP, the waterproof door can be reduced in weight, and the burden on workers involved in the installation of the waterproof door can be reduced. Can be reduced. Moreover, since plasticity is high compared with the conventional metal products, it is possible to increase the water tightness between the waterproof door, the floor groove and the side groove, thereby enhancing the water stop function. In addition to this, the height of the waterproof door is, for example, 500 mm as a standard, and since it is a cantilever structure that supports such a waterproof door at the bottom, compared to simple support on both ends that support both ends of the waterproof door, Even if the deflection becomes very small, and the opening width dimension of the entrance / exit where the waterproof door is installed changes, the size of the deflection does not change. That is, even if the width of the waterproof door (inlet opening size) changes, the bending moment due to the water pressure applied to the waterproof door does not change, so there is no need to change the thickness of the waterproof door. Therefore, the weight of the waterproof door can be reduced as a result.

また、請求項１，２の発明にあっては、上記の効果に加えて、洪水時でない通常時においては、下部支持部材は床溝の内部に横置状態で収容され、横置状態では下部支持部材の一側面が上面となり、床溝の表面を塞ぐ蓋の機能を果たすため、この上を車や人が往来しても通行や往来の妨げになることがない。つまり、横置状態の下部支持部材の一側面は床溝の溝蓋として機能するため、床溝を塞ぐための別個の溝蓋を必要せず、効率的である。しかも、下部支持部材は床溝内に収容されているため、洪水時には直ちに取り出して使用することができ、防水扉の設置時間を短縮することが可能となる。また、別個に下部支持部材を保管するためのスペースを省略でき、下部支持部材の保管場所までの移動などの作業も全く省略でき、防水扉の設置及び撤去作業を非常に効率的に行うことができる。 In addition, in the inventions of claims 1 and 2 , in addition to the above-described effects, the lower support member is accommodated in the floor groove in a normal state other than during a flood, and in the horizontal state, the lower support member is Since one side surface of the support member serves as the upper surface and functions as a lid that closes the surface of the floor groove, even if a car or a person travels on this, there is no hindrance to traffic or traffic. In other words, since one side surface of the lower support member in the horizontal state functions as a groove cover for the floor groove, a separate groove cover for closing the floor groove is not required, which is efficient. Moreover, since the lower support member is accommodated in the floor groove, it can be immediately taken out and used in the event of a flood, and the installation time of the waterproof door can be shortened. Moreover, the space for storing the lower support member separately can be omitted, and the operation of moving the lower support member to the storage location can be omitted at all, and the waterproof door can be installed and removed very efficiently. it can.

以下、図面に記載の発明を実施するための最良の形態に基づいて、この発明をより具体的に説明する。
ここで、図１（Ａ）は床支持方式防水扉構造の支持方式の概念説明用の平面図、図１（Ｂ）は床支持方式防水扉構造の支持方式の概念説明用の側断面図、図２は床支持方式防水扉構造における洪水時の床溝部分の側断面図、図３は床支持方式防水扉構造における通常時の床溝部分の側断面図、図４は床支持方式防水扉構造における洪水時の側溝部分の側断面図、図５（Ａ）は側部押圧部材の平断面図、図５（Ｂ）は側部押圧部材の側面図、図５（Ｃ）は側部押圧部材の正断面図、図６は床支持方式防水扉構造における洪水時の支持状態での力の伝わり説明用の側断面図である。 Hereinafter, the present invention will be described more specifically based on the best mode for carrying out the invention described in the drawings.
Here, FIG. 1A is a plan view for explaining the concept of the support method of the floor-supporting waterproof door structure, and FIG. 1B is a side sectional view for explaining the concept of the support method of the floor-supporting waterproof door structure. 2 is a side cross-sectional view of a floor groove portion in a flood in a floor-supporting waterproof door structure, FIG. 3 is a side cross-sectional view of a floor groove portion in a normal state in a floor-supporting waterproof door structure, and FIG. 4 is a floor-supporting waterproof door. 5A is a side sectional view of the side pressing member, FIG. 5B is a side view of the side pressing member, and FIG. 5C is a side pressing. FIG. 6 is a sectional side view for explaining the transmission of force in a support state during a flood in a floor-supporting waterproof door structure.

図において、床支持方式防水扉構造は、出入口の開口部に設置される所定高さｈの防水扉１、防水扉１が設置される床面ａに形成された床溝２、防水扉１の下部側の両面を床溝２の一側面２ａとの間で挟圧支持する下部支持部材３、開口部の左右側壁面ｂに形成された側溝４、防水扉１の左右の側端側の片面を各側溝４の一側面に押止して止水する側部押圧部材５などから構成される。   In the figure, the floor-supporting waterproof door structure includes a waterproof door 1 having a predetermined height h installed at an opening of an entrance, a floor groove 2 formed on a floor surface a on which the waterproof door 1 is installed, and a waterproof door 1. Lower support member 3 that supports both sides of the lower side with one side 2a of floor groove 2, side grooves 4 formed on left and right side wall surfaces b of the opening, one side on the left and right side end sides of waterproof door 1 Is formed by a side pressing member 5 or the like that stops water on one side surface of each side groove 4 to stop water.

防水扉１は、例えば建築物の出入口、地下街の出入口などの開口部に一時的に設置されて、集中豪雨などによって水が建物内に浸入するのを防ぐもので、厚みを有する横長な長方形状の形状している。洪水時に防水扉１はその下部側１ａが床溝２内に挿入されて挟圧支持及び止水し、左右側端側１ｂが左右の側溝４内に挿入されて止水する構造になっている。   The waterproof door 1 is, for example, temporarily installed at an opening of a building entrance or an underground street entrance to prevent water from entering the building due to heavy rain, etc., and has a horizontally long rectangular shape. It has the shape of In the event of a flood, the waterproof door 1 has a structure in which the lower side 1a is inserted into the floor groove 2 to support clamping and stop water, and the left and right end sides 1b are inserted into the left and right side grooves 4 to stop water. .

長方形状の防水扉１は高さが所定高さｈの例えば５００mm程度であり、その下部側１ａが床溝２内に設置された下部支持部材３により、床溝２内の一側面に挟圧されて支持される。所定高さｈの防水扉１はその下部側１ａが支持されることで洪水時の水圧に抵抗できる構造になっている。防水扉１はその高さが所定高さｈの例えば５００mm程度であり、高さが任意に変更することがないので、防水扉１は所定の高さで下部側１ａが支持されるのみで洪水時の水圧に十分に抵抗できる構造になっている。   The rectangular waterproof door 1 has a predetermined height h of about 500 mm, for example, and its lower side 1a is clamped on one side surface of the floor groove 2 by the lower support member 3 installed in the floor groove 2. Has been supported. The waterproof door 1 having a predetermined height h has a structure capable of resisting water pressure during a flood by supporting the lower side 1a. The waterproof door 1 has a predetermined height h of about 500 mm, for example, and the height is not arbitrarily changed. Therefore, the waterproof door 1 is flooded only by supporting the lower side 1a at the predetermined height. It has a structure that can sufficiently resist the water pressure of the time.

防水扉１は高さが所定高さｈで一定でその下部側１ａが支持されることで洪水時の水圧に抵抗できる構造、つまり片持梁での支持構造になっていて、防水扉１の左右両側端側１ｂでは支持しない構造つまり両端支持構造でないため、防水扉１の長さが任意に長くなっていても、防水扉１の長さに無関係に同じ構造で支持することができる。   The waterproof door 1 has a structure with a predetermined height h that is constant and supports the lower side 1a so that it can resist the water pressure during flooding, that is, a cantilever support structure. Since it is not a structure that is not supported on the left and right side ends 1b, that is, a both-end support structure, even if the waterproof door 1 is arbitrarily long, it can be supported by the same structure regardless of the length of the waterproof door 1.

防水扉１は、その材質がＦＲＰ（ガラス繊維強化プラスチック）製から構成されている。ＦＲＰは比重が一般に1.6〜1.8で、従来の鋼製防水扉の比重の約7.8に比べて４分の１以下であり、かなり軽量化することができる。前記したように、防水扉を操作する人（管理人）は多くのビル等においてその年齢が高く、その負担は考えている以上に大きい。強度が高く、比重が小さいＦＲＰを使用することで軽量化を計りこの問題を解決できることになる。   The waterproof door 1 is made of FRP (glass fiber reinforced plastic). FRP has a specific gravity of generally 1.6 to 1.8, which is less than a quarter of the specific gravity of a conventional steel waterproof door, and can be considerably reduced in weight. As described above, the person (administrator) who operates the waterproof door is older in many buildings and the burden is larger than expected. By using FRP with high strength and low specific gravity, this problem can be solved by reducing the weight.

また、前記したように、防水扉の材質がステンレスやアルミの場合には、溶接構造となっているので溶接歪が発生し、平面度をだすのがむつかしく、さらに防水扉の剛性が大きいので、手で締付金具を押し付けるぐらいの力では、防水扉は変形せず、結局完全な止水部が構成されない不都合が生じる。これに対して本願発明の防水扉１は、その材質がＦＲＰの為、可塑性を有しており、防水扉１が変形していたり、埋込枠が変形していても、この製品を構成している支持金具を締め付ければ、防水扉１は埋込枠にそって変形しながら、ゴムを圧縮し、ゴムと埋込枠が隙間なくなじんでいき、もちろん最終的に支持金具を締め付けてしまえば、ＦＲＰ製の防水扉１と埋込枠は、一体となり、本来のＦＲＰの剛性が発揮される。   In addition, as described above, when the material of the waterproof door is stainless steel or aluminum, since it has a welded structure, welding distortion occurs, it is difficult to obtain flatness, and the rigidity of the waterproof door is large, With the force of pressing the tightening bracket by hand, the waterproof door will not be deformed, resulting in the inconvenience that a complete water stop is not formed. On the other hand, the waterproof door 1 of the present invention has plasticity because the material is FRP, and even if the waterproof door 1 is deformed or the embedding frame is deformed, this product is constituted. If the support bracket is tightened, the waterproof door 1 will be deformed along the embedded frame, compressing the rubber, and the rubber and the embedded frame will become familiar without any gaps. Of course, the support bracket will eventually be tightened. For example, the waterproof door 1 made of FRP and the embedding frame are integrated, and the original rigidity of FRP is exhibited.

床溝２及び側溝４の一側面と接する防水扉１の下部側１ａ及び両側端側１ｂの片面には、弾性止水板１１がそれぞれ取り付けられている。床溝２と接する側に取り付けられる弾性止水板１１は防水扉１の下部側１ａに水平方向に取り付けられ、側溝４と接する側に取り付けられる弾性止水板１１は防水扉１の左右側端側１ｂに上下方向に取り付けられている。各弾性止水板１１は床溝２及び側溝４の一側面と密着して止水するもので、例えばゴム製パッキンが使用される。   Elastic water stop plates 11 are respectively attached to one side of the lower side 1a and the side end sides 1b of the waterproof door 1 in contact with one side surface of the floor groove 2 and the side groove 4. The elastic water stop plate 11 attached to the side in contact with the floor groove 2 is attached horizontally to the lower side 1 a of the waterproof door 1, and the elastic water stop plate 11 attached to the side in contact with the side groove 4 is the left and right side ends of the waterproof door 1. Attached to the side 1b in the vertical direction. Each elastic water stop plate 11 is in close contact with one side surface of the floor groove 2 and the side groove 4 and stops water. For example, rubber packing is used.

床溝２の一側面と接する防水扉１の下部側１ａの片面には、弾性止水板１１を挟んでその上下に受圧板１２が平行にそれぞれ取り付けられている。上下の受圧板１２は防水扉１の下部側１ａが床溝２の一側面に押し付けられる際に、その圧力を均等にして分散して床溝２の一側面に作用させて防水扉１が傾いたりするのを防ぐ機能を果たす。   On one surface of the lower side 1a of the waterproof door 1 in contact with one side surface of the floor groove 2, pressure receiving plates 12 are attached in parallel above and below the elastic water stop plate 11, respectively. When the lower side 1 a of the waterproof door 1 is pressed against one side surface of the floor groove 2, the upper and lower pressure receiving plates 12 cause the waterproof door 1 to incline by distributing the pressure evenly and acting on one side surface of the floor groove 2. It fulfills the function to prevent

洪水時に防水扉１の下部側１ａが挿入される床溝２は、出入口の開口部の床面ａに開口幅の全幅方向にわたって形成されている。床溝２はその断面が溝深さに比べ溝幅が大きい横長な矩形断面から構成されている。床溝２には防水扉１の下部側１ａを挟圧して支持する下部支持部材３が収容されている。   The floor groove 2 into which the lower side 1a of the waterproof door 1 is inserted in the event of a flood is formed on the floor surface a of the opening of the entrance / exit over the entire width direction of the opening width. The floor groove 2 is composed of a horizontally long rectangular section whose section has a larger groove width than the groove depth. The floor groove 2 accommodates a lower support member 3 that supports the lower side 1a of the waterproof door 1 by sandwiching it.

出入口の開口部の左右側壁面ｂには床溝２の左右の各端部から上向き方向に洪水時に防水扉１の左右の側端側１ｂが挿入される側溝４がそれぞれ形成されている。各側溝４には防水扉１の側端側１ｂを押圧して止水するための側部押圧部材５がそれぞれ配置されている。   Side walls 4 into which the left and right side end sides 1b of the waterproof door 1 are inserted in the upward direction from the left and right ends of the floor groove 2 are respectively formed on the left and right side wall surfaces b of the opening of the entrance / exit. Each side groove 4 is provided with a side pressing member 5 for pressing the side end side 1b of the waterproof door 1 to stop water.

上下方向に形成された左右の各側溝４はその下端が床面ａに水平状に形成された床溝２の両端と繋がっている。各側溝４の断面は例えば床溝２の断面と同一の断面形状になっている。即ち、各側溝４は床溝２と同様に、断面が溝深さに比べ溝幅が大きい横長な矩形断面から構成されている。   Each of the left and right side grooves 4 formed in the vertical direction has a lower end connected to both ends of the floor groove 2 formed horizontally on the floor surface a. The cross-section of each side groove 4 has the same cross-sectional shape as that of the floor groove 2, for example. That is, each side groove 4 is formed of a horizontally long rectangular cross section whose cross section has a groove width larger than the groove depth, like the floor groove 2.

下部支持部材３は、洪水時には縦置状態の一側面３ａで防水扉１の下部側１ａの両面を床溝２の一側面２ａとの間で挟圧支持すると共に防水扉１の下部側１ａの片面に取り付けた上記弾性止水板１１を床溝２の一側面２ａに押止して当該弾性止水板１１により止水する機能を果たす。下部支持部材３はその取り扱いが容易になるようにその長さは例えば２ｍ程になっていて、これが複数床溝２内に配置されている。この理由は下部支持部材３を９０度回転させて横置状態から縦置状態にするとき一人でもてるようにするためである。   The lower support member 3 supports the both sides of the lower side 1a of the waterproof door 1 with the one side 2a of the floor groove 2 with one side 3a in a vertically placed state in the event of a flood, and at the lower side 1a of the waterproof door 1 The elastic water stop plate 11 attached to one side is pressed against the one side surface 2a of the floor groove 2 and water is stopped by the elastic water stop plate 11. The lower support member 3 has a length of, for example, about 2 m so that it can be easily handled, and is disposed in the plurality of floor grooves 2. This is because when the lower support member 3 is rotated 90 degrees to change from the horizontal position to the vertical position, only one person can be provided.

また、下部支持部材３は、通常時つまり防水扉１が使用されない時には横置状態、つまり縦置状態から９０度横に倒した状態で床面ａと略同一平面となって床溝２を塞ぐような状態で床溝２内に収容されるようになっている。すなわち、下部支持部材３の一部は横置状態では床溝２の表面の蓋のような機能を果たす。下部支持部材３は、縦置状態で一側面３ａとなる部分が９０度横に倒した横置状態では上面側となって床溝２の表面の蓋のような機能を果たす。   Further, the lower support member 3 becomes substantially flush with the floor surface a and closes the floor groove 2 in a horizontal state, that is, in a state where the waterproof door 1 is tilted 90 degrees from the vertical state when the waterproof door 1 is not used. It is accommodated in the floor groove 2 in such a state. That is, a part of the lower support member 3 functions like a lid on the surface of the floor groove 2 in the horizontal state. The lower support member 3 functions as a lid on the surface of the floor groove 2 when it is in the horizontal position in which the portion that becomes the one side surface 3a in the vertical position is turned 90 degrees sideways.

下部支持部材３は、防水扉１を使用しない通常時には床溝２内に横置状態で収容することができ、洪水時には直ちに使用できると共に別途に保管場所を必要とすることがなく、しかもその収容した際には一側面３ａが床溝２の蓋としての機能を果たすため、床溝２が通常時に通行の妨げとなるのを防ぐための蓋を別途に取り付ける必要もない。   The lower support member 3 can be accommodated in the floor groove 2 in a normal state when the waterproof door 1 is not used, can be used immediately in the event of a flood, and does not require a separate storage location. In this case, since the one side surface 3a functions as a cover for the floor groove 2, it is not necessary to separately attach a cover for preventing the floor groove 2 from obstructing passage during normal times.

下部支持部材３は、洪水時の縦置状態でその断面が溝型断面となり、通常時の横置状態でその断面がコ字型断面となっている。縦置状態で溝型断面の左右側面部分を構成する平行な一側面３ａと他側面３ｂと、縦置状態で溝型断面の底面部分を構成する連結面３ｃとから構成されている。縦置状態で連結面３ｃは一側面３ａと他側面３ｂの下端間に配置されている。   The lower support member 3 has a groove-shaped cross section in a vertical state during a flood, and has a U-shaped cross section in a normal horizontal state. It is comprised from the parallel one side 3a and the other side 3b which comprise the right-and-left side part of a groove type cross section in the vertical state, and the connection surface 3c which comprises the bottom face part of a groove type cross section in the vertical state. In the vertically placed state, the connecting surface 3c is disposed between the lower ends of the one side surface 3a and the other side surface 3b.

縦置状態から９０度横に倒した横置状態では、一側面３ａは床溝２の上面側となり、他側面３ｂは床溝２の底面側２ｃとなり、連結面３ｃは床溝２の一側面２ａ側となる。洪水時の縦置状態でその断面が溝型断面となる下部支持部材３の内側部分には溝型形状を保持するブラケット３ｄが適宜間隔で配置されている。   In the horizontal state in which it is tilted 90 degrees from the vertical state, one side surface 3a is the upper surface side of the floor groove 2, the other side surface 3b is the bottom surface side 2c of the floor groove 2, and the connecting surface 3c is one side surface of the floor groove 2. 2a side. Brackets 3d that hold the groove shape are arranged at appropriate intervals on the inner side portion of the lower support member 3 whose cross section is a groove-shaped cross section in a vertically placed state during a flood.

下部押圧力付与軸３１は、床溝２の一側面２ａと向かい合う他側面２ｂに先端が当接しその反作用で下部支持部材３の縦置状態の一側面３ａを防水扉１に向けて押圧移動させる機能を有する。下部押圧力付与軸３１は床溝２内に挿入された防水扉１に取り付けた上下の受圧板１２の中間高さ位置に対応する下部支持部材３の縦置状態の他側面３ｂの高さ位置に貫通状態で螺合されている。下部押圧力付与軸３１は、適宜の間隔例えば５００ｍｍの間隔で下部支持部材３に取り付けられている。   The lower pressing force applying shaft 31 has its tip abutted against the other side surface 2 b facing the one side surface 2 a of the floor groove 2, and pushes and moves the one side surface 3 a of the lower support member 3 toward the waterproof door 1 by its reaction. It has a function. The lower pressing force applying shaft 31 is located at the height position of the other side surface 3b of the lower supporting member 3 in the vertical state corresponding to the intermediate height position of the upper and lower pressure receiving plates 12 attached to the waterproof door 1 inserted into the floor groove 2. Screwed in a through state. The lower pressing force applying shaft 31 is attached to the lower support member 3 at an appropriate interval, for example, an interval of 500 mm.

すなわち、下部支持部材３の他側面３ｂの対応する高さ位置には螺子孔が形成され、下部押圧力付与軸３１の外周には螺子山が刻設されていて、下部押圧力付与軸３１はその外周の螺子山が螺子孔に螺合されることで螺子運動により進退動する構造になっている。   That is, a screw hole is formed at a corresponding height position of the other side surface 3b of the lower support member 3, a screw thread is formed on the outer periphery of the lower pressing force applying shaft 31, and the lower pressing force applying shaft 31 is The outer peripheral screw thread is screwed into the screw hole so that the screw thread moves forward and backward.

下部押圧力付与軸３１の位置は防水扉１に取り付けた上下の受圧板１２の中間高さ位置に対応しており、下部押圧力付与軸３１からの付与される押圧力は上下の受圧板１２に均等に分散されるため、防水扉１は下部押圧力付与軸３１からの押圧力によって傾いたりするのが防止される。   The position of the lower pressing force applying shaft 31 corresponds to the intermediate height position of the upper and lower pressure receiving plates 12 attached to the waterproof door 1, and the pressing force applied from the lower pressing force applying shaft 31 is the upper and lower pressure receiving plates 12. Therefore, the waterproof door 1 is prevented from being tilted by the pressing force from the lower pressing force applying shaft 31.

また、下部押圧力付与軸３１は下部支持部材３の他側面３ｂに螺合されているため、その前進及び後退の移動は微小移動となり、押圧力の細かな微調整が可能となり、また微小移動のために大きな押圧力を下部押圧力付与軸３１は下部支持部材３を通じて防水扉１に付与することができ、防水扉１を下部支持部材３の一側面３ａと床溝２の一側面２ａとの間で挟圧して支持させることができる。   Further, since the lower pressing force applying shaft 31 is screwed to the other side surface 3b of the lower support member 3, the forward and backward movements are fine movements, and the fine pressing force can be finely adjusted. For this reason, the lower pressing force applying shaft 31 can apply a large pressing force to the waterproof door 1 through the lower support member 3, and the waterproof door 1 is attached to one side 3 a of the lower support member 3 and one side 2 a of the floor groove 2. It is possible to support by pressing between the two.

下部押圧力付与軸３１の後部には当該押圧力付与軸３１を軸転させる下部ハンドル３２が設けられている。作業員はこの下部ハンドル３２を手で回すことにより下部押圧力付与軸３１を軸転させて、螺子運動により下部押圧力付与軸３１の先端を床溝２の他側面２ｂに当接させて、その反作用によって下部支持部材３を床溝２の一側面２ａ側に向けて押圧移動させることができる。   A lower handle 32 for rotating the pressing force applying shaft 31 is provided at the rear of the lower pressing force applying shaft 31. An operator rotates the lower pressing force applying shaft 31 by turning the lower handle 32 by hand, and the tip of the lower pressing force applying shaft 31 is brought into contact with the other side surface 2b of the floor groove 2 by screw movement. By the reaction, the lower support member 3 can be pressed and moved toward the one side surface 2 a of the floor groove 2.

床溝２内に挿入された防水扉１に取り付けた上下の受圧板１２の中間高さ位置に対応する下部支持部材３の縦置状態の一側面３ａの高さ位置には下部押込板３３が取り付けられている。下部押込板３３は下部支持部材３の一側面３ａと接する側の防水扉１の表面を直接押圧する板である。下部支持部材３の一側面３ａや防水扉１の表面が僅かに変形している場合、下部支持部材３の一側面３ａが防水扉１の表面を均一に押圧できなくなるのを回避するために、下部押込板３３は取り付けられている。   A lower pushing plate 33 is provided at the height position of the one side surface 3a of the lower support member 3 corresponding to the intermediate height position of the upper and lower pressure receiving plates 12 attached to the waterproof door 1 inserted into the floor groove 2. It is attached. The lower pushing plate 33 is a plate that directly presses the surface of the waterproof door 1 on the side in contact with the one side surface 3 a of the lower support member 3. In order to avoid that one side surface 3a of the lower support member 3 and the surface of the waterproof door 1 are slightly deformed, the one side surface 3a of the lower support member 3 cannot press the surface of the waterproof door 1 uniformly. The lower pushing plate 33 is attached.

側部押圧部材５は、洪水時に一側面５ａが防水扉１の左右の側端側１ｂの片面を各側溝４の一側面４ａに押止して片面に取り付けた上記弾性止水板１１により止水させる機能を果たす。側部押圧部材５は左右の各側溝４の内側にそれぞれ配置されている。   The side pressing member 5 is stopped by the elastic water stop plate 11 attached to the one side surface 5a of one side surface 5a of the waterproof door 1 on one side surface 4a of each side groove 4 while the side surface pressing member 5 is flooded. Performs the function of water The side pressing members 5 are respectively arranged inside the left and right side grooves 4.

各側部押圧部材５は、その断面が溝型断面となっていて、溝型断面の左右側面部分を構成する平行な一側面５ａと他側面５ｂと、溝型断面の底面部分を構成する連結面５ｃとから構成されている。   Each side pressing member 5 has a groove-shaped cross section, and one parallel side surface 5a and another side surface 5b constituting the left and right side surface portions of the groove type cross section, and a connection constituting the bottom surface portion of the groove type cross section. It is comprised from the surface 5c.

側部押圧力付与軸５１は、側溝４の一側面４ａと向かい合う他側面４ｂに先端が当接しその反作用で側部押圧部材５の一側面５ａを防水扉１に向けて押圧移動させる機能を有する。側部押圧力付与軸５１は側溝４内に挿入された防水扉１に取り付けた弾性止水板１１と同一位置に対応する側部押圧部材５の他側面５ｂの位置に貫通状態で螺合されている。   The side pressing force applying shaft 51 has a function of causing the tip to abut on the other side surface 4b facing the one side surface 4a of the side groove 4 and pressing and moving the one side surface 5a of the side pressing member 5 toward the waterproof door 1 by its reaction. . The side pressing force applying shaft 51 is threadably engaged with the position of the other side surface 5b of the side pressing member 5 corresponding to the same position as the elastic water stop plate 11 attached to the waterproof door 1 inserted into the side groove 4. ing.

すなわち、側部押圧部材５の他側面５ｂの対応する位置には螺子孔が形成され、側部押圧力付与軸５１の外周には螺子山が刻設されていて、側部押圧力付与軸５１はその外周の螺子山が螺子孔に螺合されることで螺子運動により進退動する構造になっている。   That is, a screw hole is formed at a corresponding position on the other side surface 5 b of the side pressing member 5, and a screw thread is formed on the outer periphery of the side pressing force applying shaft 51. The screw thread of the outer periphery is structured to move forward and backward by screw movement by being screwed into the screw hole.

側部押圧力付与軸５１の位置は防水扉１に取り付けた弾性止水板１１の位置に対応しており、側部押圧力付与軸５１からの反作用で付与される押圧力は同じ位置ある弾性止水板１１に作用するため、防水扉１の弾性止水板１１は側溝４の一側面４ａに十分に密着して止水機能が遺憾なく発揮されて、防水扉１の左右の側端側１ｂから水漏れが生じるのを確実に阻止することができる。   The position of the side pressing force applying shaft 51 corresponds to the position of the elastic water blocking plate 11 attached to the waterproof door 1, and the pressing force applied by the reaction from the side pressing force applying shaft 51 is the same elasticity. Since it acts on the water stop plate 11, the elastic water stop plate 11 of the waterproof door 1 is sufficiently adhered to the one side surface 4 a of the side groove 4 so that the water stop function is fully exhibited. It is possible to reliably prevent water leakage from 1b.

また、側部押圧力付与軸５１は側部押圧部材５の他側面５ｂに螺合されているため、その前進及び後退の移動は微小移動となり、押圧力の細かな微調整が可能となり、また微小移動のために大きな押圧力を側部押圧力付与軸５１は側部押圧部材５を通じて防水扉１に付与することができ、防水扉１の弾性止水板１１の側溝４の一側面４ａに対する密着を更に高めて止水効果を更に高めることができる。   Further, since the side pressing force applying shaft 51 is screwed to the other side surface 5b of the side pressing member 5, the forward and backward movements are minute movements, and fine adjustment of the pressing force is possible. The side pressing force applying shaft 51 can apply a large pressing force for the minute movement to the waterproof door 1 through the side pressing member 5, and the one side 4 a of the side groove 4 of the elastic water stop plate 11 of the waterproof door 1. Adhesion can be further enhanced to further enhance the water stop effect.

側部押圧力付与軸５１の後部には当該押圧力付与軸５１を軸転させる側部ハンドル５２が設けられている。作業員はこの側部ハンドル５２を手で回すことにより側部押圧力付与軸５１を軸転させて、螺子運動により側部押圧力付与軸５１の先端を側溝４の他側面４ｂに当接させて、その反作用によって側部押圧部材５を側溝４の一側面４ａ側に向けて押圧移動させることができる。   A side handle 52 for rotating the pressing force applying shaft 51 is provided at the rear portion of the side pressing force applying shaft 51. The operator rotates the side handle 52 by hand to rotate the side pressing force applying shaft 51, and the tip of the side pressing force applying shaft 51 is brought into contact with the other side surface 4 b of the side groove 4 by screw movement. Thus, the side pressing member 5 can be pressed and moved toward the one side surface 4a of the side groove 4 by the reaction.

また、側部押圧部材５が側溝４から外れないように、側部押圧部材５の連結面５ｃと側溝４の底面４ｃとは遊嵌状に連結されている。側部押圧部材５は連結面５ｃが側溝４の底面４ｃに沿って前後にスライドできる状態で連結されている。このため、側部押圧部材５の連結面５ｃにはスライドできるように長孔５ｄが形成され、この長孔５ｄに側溝４の底面４ｃと連結する連結ボルト５ｅが取り付けられている。   Further, the connecting surface 5c of the side pressing member 5 and the bottom surface 4c of the side groove 4 are connected in a loose fit so that the side pressing member 5 does not come off from the side groove 4. The side pressing members 5 are connected so that the connecting surface 5c can slide back and forth along the bottom surface 4c of the side groove 4. For this reason, a long hole 5d is formed in the connecting surface 5c of the side pressing member 5 so as to be slidable, and a connecting bolt 5e connected to the bottom surface 4c of the side groove 4 is attached to the long hole 5d.

次に、上記発明を実施するための最良の形態の構成に基づく作用について以下説明する。
洪水時でない通常時においては、下部支持部材３は床溝２の内部に横置状態で収容されている。横置状態では下部支持部材３の一側面３ａが上面となる。一側面３ａの上面の高さは床面ａの高さと略同一である。横置状態の下部支持部材３の一側面３ａは、床溝２の表面を塞ぐため、この上を車や人が往来しても支障をきたすことがない。 Next, the operation based on the configuration of the best mode for carrying out the invention will be described below.
The lower support member 3 is accommodated in the floor groove 2 in a horizontal state during a normal time other than a flood. In the horizontal position, one side surface 3a of the lower support member 3 is the upper surface. The height of the upper surface of the one side surface 3a is substantially the same as the height of the floor surface a. Since one side surface 3a of the lower support member 3 in the horizontal state closes the surface of the floor groove 2, there is no problem even if a car or a person goes on the side surface 3a.

つまり、横置状態の下部支持部材３の一側面３ａは床溝２の溝蓋として機能するため、床溝２を塞ぐための別個の溝蓋を必要せず、効率的である。しかも、下部支持部材３は床溝２内に収容されているため、洪水時には直ちに取り出して使用することができ、効率的な使用が可能となる。また、別個に下部支持部材３を保管するためのスペースを省略でき、下部支持部材３の保管場所までの移動などの作業も全く省略でき、非常に効率的である。   That is, since the one side surface 3a of the lower support member 3 in the horizontal state functions as a groove cover of the floor groove 2, a separate groove cover for closing the floor groove 2 is not required, which is efficient. In addition, since the lower support member 3 is accommodated in the floor groove 2, it can be immediately taken out and used in the event of a flood, enabling efficient use. Further, a space for storing the lower support member 3 separately can be omitted, and operations such as movement of the lower support member 3 to the storage location can be omitted at all, which is very efficient.

洪水になると予想される時には、床溝２内に横置状態で収容していた下部支持部材３を９０度起こして縦置状態にする。下部支持部材３はその取り扱いが容易になるようにその長さは例えば２ｍ程になっているので、一人でも簡単に横置状態から縦置状態に起こすことができる。縦置状態にして下部支持部材３の一側面３ａと床溝２の一側面２ａとの間に防水扉１の下部側１ａが挿入できる隙間をあけ、保管場所から持ち出した防水扉１の下部側１ａをその隙間に上方から挿入して差し込む。   When it is predicted that a flood will occur, the lower support member 3 accommodated horizontally in the floor groove 2 is raised 90 degrees to be placed vertically. Since the length of the lower support member 3 is, for example, about 2 m so that it can be easily handled, even one person can easily raise from the horizontal position to the vertical position. The lower side of the waterproof door 1 taken out from the storage place with a gap in which the lower side 1a of the waterproof door 1 can be inserted between the one side surface 3a of the lower support member 3 and the one side surface 2a of the floor groove 2 in a vertical state. 1a is inserted into the gap from above.

防水扉１の下部側１ａを床溝２と下部支持部材３との間の隙間に差し込んだ後、各下部支持部材３の他側面３ｂに適宜間隔で取り付けられた複数の下部押圧力付与軸３１の下部ハンドル３２を手で一定方向回りに回転させる。一定方向に回転させると、下部押圧力付与軸３１は螺子運動によって、先端が他側面３ｂから突出して床溝２の他側面２ｂに向かって移動する。移動した下部押圧力付与軸３１の先端が床溝２の他側面２ｂに当接した後も更に下部押圧力付与軸３１を回転させると、下部押圧力付与軸３１が螺合している他側面２ｂの下部支持部材３は相対的に床溝２の一側面２ａに向かって移動する。   After inserting the lower side 1a of the waterproof door 1 into the gap between the floor groove 2 and the lower support member 3, a plurality of lower pressing force application shafts 31 attached to the other side surface 3b of each lower support member 3 at appropriate intervals. The lower handle 32 is rotated by a hand around a certain direction. When rotated in a certain direction, the lower pressing force applying shaft 31 is moved toward the other side surface 2b of the floor groove 2 with its tip protruding from the other side surface 3b by screw motion. When the lower pressing force application shaft 31 is further rotated after the tip of the moved lower pressing force application shaft 31 has come into contact with the other side surface 2b of the floor groove 2, the other side surface with which the lower pressing force application shaft 31 is screwed. The lower support member 3 of 2b moves relatively toward the one side surface 2a of the floor groove 2.

移動する下部支持部材３はその一側面３ａが、挿入されている防水扉１の下部側１ａに当接する。詳しくは、一側面３ａに取り付けられた下部押込板３３が防水扉１の下部側１ａの表面に当接する。防水扉１の下部側１ａの表面に当接した下部支持部材３の一側面３ａは、防水扉１の下部側１ａを押圧して床溝２の一側面２ａに向けて移動させる。下部支持部材３とこれに押圧された防水扉１とは一緒になって床溝２の一側面２ａに向けて移動する。   One side surface 3a of the moving lower support member 3 comes into contact with the lower side 1a of the waterproof door 1 inserted therein. Specifically, the lower pushing plate 33 attached to the one side surface 3 a abuts on the surface of the lower side 1 a of the waterproof door 1. One side surface 3 a of the lower support member 3 that is in contact with the surface of the lower side 1 a of the waterproof door 1 presses the lower side 1 a of the waterproof door 1 and moves it toward one side 2 a of the floor groove 2. The lower support member 3 and the waterproof door 1 pressed by the lower support member 3 move together toward the one side surface 2a of the floor groove 2.

押圧されて移動した防水扉１はその下部側１ａに取り付けられた例えばゴム製のパッキンなどが使用された弾性止水板１１が床溝２の一側面２ａに押し付けられ、弾性止水板１１は圧縮されて止水部を構成する。   The waterproof door 1 that has been moved by being pressed is pressed against the one side surface 2a of the floor groove 2 by the elastic water stop plate 11 attached to the lower side 1a using, for example, rubber packing. Compressed to form a water stop.

ここで重要なのは下部押圧力付与軸３１の力をバランスよく防水扉１に伝え、さらに、その力の外的つりあいを作り出す必要がある。前記したように下部支持部材３の一側面３ａには下部押込板３３が取り付けられている。これは下部押圧力付与軸３１の回転によって下部支持部材３が移動して防水扉１に接触するとき、確実にこの下部押込板３３の幅の範囲内で、下部押圧力付与軸３１による移動力を防水扉１に伝えるためである。   What is important here is that it is necessary to transmit the force of the lower pressing force applying shaft 31 to the waterproof door 1 in a well-balanced manner and to create an external balance of the force. As described above, the lower pressing plate 33 is attached to the one side surface 3 a of the lower support member 3. This is because when the lower support member 3 is moved by the rotation of the lower pressing force applying shaft 31 and comes into contact with the waterproof door 1, the moving force by the lower pressing force applying shaft 31 is surely within the range of the width of the lower pressing plate 33. This is to convey to the waterproof door 1.

これをつけないと、下部支持部材３が防水扉１の方向に移動したとき、下部支持部材３の一側面３ａのどの部分が防水扉１に接触するか確定できない。下部支持部材３の一側面３ａの上部が接触すると防水扉１の下部は拘束がなくなり、防水扉１はふらつく。また、下部支持部材３の一側面３ａの下部が接触すると、同じように防水扉１の上部は拘束がなくなり、防水扉１はふらつく。つまり図で示すように下部押圧力付与軸３１の移動力Ｐの位置が、２個の上下の受圧板１２の内側に常にあることで力のつりあいが生じ、防水扉１が固定されるということである。また、このような方法をとることで、例えばゴム製パッキンなどが使用される弾性止水板１１に過大な力がかからなくなる。   Without this, when the lower support member 3 moves in the direction of the waterproof door 1, it cannot be determined which part of the one side surface 3 a of the lower support member 3 contacts the waterproof door 1. When the upper part of the one side surface 3a of the lower support member 3 comes into contact, the lower part of the waterproof door 1 is not restrained, and the waterproof door 1 fluctuates. Moreover, when the lower part of the one side surface 3a of the lower support member 3 contacts, similarly, the upper part of the waterproof door 1 is not restrained, and the waterproof door 1 is staggered. That is, as shown in the figure, the position of the moving force P of the lower pressing force applying shaft 31 is always inside the two upper and lower pressure receiving plates 12, so that the balance of force occurs and the waterproof door 1 is fixed. It is. Moreover, by taking such a method, an excessive force is not applied to the elastic water stop plate 11 in which, for example, rubber packing is used.

このようにして、防水扉１はその下部側１ａが床溝２の一側面２ａと下部支持部材３の一側面３ａとの間で挟圧されて支持され、従来のように防水扉の長さ方向の両側端側１ｂを側溝４で支えるのではなく床溝２で支える構造になっている。   In this way, the waterproof door 1 is supported by the lower side 1a being sandwiched between the one side 2a of the floor groove 2 and the one side 3a of the lower support member 3, and the length of the waterproof door as in the prior art. The structure is such that both side ends 1b in the direction are supported not by the side grooves 4 but by the floor grooves 2.

通常の防水扉は高さ５００ｍｍ位が標準となっている。依って仮に高さが５００ｍｍの製品とすると、長さＬ＝５００ｍｍの片持梁と考えられ、両端単純支持に比較すると、そのたわみが非常に小さくなる。さらに、開口寸法が変化しても、そのたわみの大きさは変わらず、つまり扉の剛性を変える必要がなくなり常に同じ扉の厚みで良いのである。   Standard waterproof doors are about 500mm in height. Therefore, if the product has a height of 500 mm, it can be considered as a cantilever having a length L = 500 mm, and its deflection is very small compared to simple support at both ends. Further, even if the opening size changes, the size of the deflection does not change, that is, it is not necessary to change the rigidity of the door, and the same door thickness is always required.

図のように防水扉１を床溝２内の下部支持部材３で挟圧して固定することにより、防水扉１の幅（入口開口寸法）が変わっても防水扉１に加わる水圧による曲げモーメントは、変化しないので防水扉１の厚みを変える必要はない。従って、防水扉１の重量を結果的に軽くすることができる。   As shown in the figure, when the waterproof door 1 is clamped and fixed by the lower support member 3 in the floor groove 2, even if the width of the waterproof door 1 (inlet opening size) changes, the bending moment due to the water pressure applied to the waterproof door 1 is Since it does not change, there is no need to change the thickness of the waterproof door 1. Therefore, the weight of the waterproof door 1 can be reduced as a result.

防水扉１の下部側１ａを床溝２で支持し且つ止水した後に、左右の側溝４に挿入された防水扉１の長さ方向の両側端側１ｂを側部押圧部材５により押し付けて止水する。すなわち、各側部押圧部材５の他側面５ｂに適宜間隔で取り付けられた複数の側部押圧力付与軸５１の側部ハンドル５２を手で一定方向回りに回転させる。   After the lower side 1a of the waterproof door 1 is supported by the floor groove 2 and water is stopped, both side ends 1b in the length direction of the waterproof door 1 inserted into the left and right side grooves 4 are pressed by the side pressing members 5 and stopped. Water. That is, the side handles 52 of the plurality of side pressing force applying shafts 51 attached to the other side surface 5b of each side pressing member 5 at appropriate intervals are manually rotated around a certain direction.

一定方向に回転させると、側部押圧力付与軸５１は螺子運動によって、先端が他側面５ｂから突出して側溝４の他側面４ｂに向かって移動する。移動した側部押圧力付与軸５１の先端が側溝４の他側面４ｂに当接した後も更に側部押圧力付与軸５１を回転させると、側部押圧力付与軸５１が螺合している他側面５ｂの側部押圧部材５は相対的に側溝４の一側面４ａに向かって移動する。   When rotating in a certain direction, the side pressing force applying shaft 51 is moved toward the other side surface 4b of the side groove 4 by protruding from the other side surface 5b by screw movement. When the side pressing force applying shaft 51 is further rotated even after the tip of the moved side pressing force applying shaft 51 comes into contact with the other side surface 4b of the side groove 4, the side pressing force applying shaft 51 is screwed. The side pressing member 5 on the other side surface 5 b moves relatively toward the one side surface 4 a of the side groove 4.

移動する側部押圧部材５はその一側面５ａが、挿入されている防水扉１の各側端側１ｂにそれぞれ当接する。防水扉１の各側端側１ｂの表面に当接した側部押圧部材５の一側面５ａは、防水扉１の各側端側１ｂを押圧して側溝４の一側面４ａに向けて移動させる。側部押圧部材５とこれに押圧された防水扉１とは一緒になって側溝４の一側面４ａに向けて移動する。   One side surface 5a of the moving side pressing member 5 abuts on each side end side 1b of the waterproof door 1 inserted therein. One side surface 5a of the side pressing member 5 that is in contact with the surface of each side end side 1b of the waterproof door 1 presses each side end side 1b of the waterproof door 1 and moves it toward one side 4a of the side groove 4. . The side pressing member 5 and the waterproof door 1 pressed by the side pressing member 5 move toward the one side surface 4a of the side groove 4 together.

押圧されて移動した防水扉１はその各側端側１ｂに取り付けられた例えばゴム製のパッキンなどが使用された弾性止水板１１が側溝４の一側面４ａに押し付けられ、弾性止水板１１は圧縮されて止水部を構成する。   The waterproof door 1 that has been moved by being pressed is pressed against the one side surface 4a of the side groove 4 by the elastic water stop plate 11 attached to each side end 1b using, for example, rubber packing. Is compressed to form a water stop.

側溝４の役目は、防水扉１の左右両側端側１ｂの止水が目的である。つまり側溝４に設置される側部押圧部材５や側部押圧力付与軸５１は例えばゴム製パッキンが使用される弾性止水板１１を圧縮するためのものである。   The purpose of the side groove 4 is to stop the water on the left and right side ends 1b of the waterproof door 1. That is, the side pressing member 5 and the side pressing force applying shaft 51 installed in the side groove 4 are for compressing the elastic water stop plate 11 in which, for example, rubber packing is used.

本願発明の製品は、水圧を床溝２で支持するので、開口寸法が大きい、つまり防水扉１の長さが長くなっても１枚板で設計することができる。どうしても分割が必要な場合は、既存の製品はその分割部に支柱をたてなければならないが、本願発明の製品は、分割部に外力が加わらないので、支柱は必要ない。ただし、分割部にワンタッチ式の止水ゴムを取り付ける。   Since the product of the present invention supports the water pressure by the floor groove 2, it can be designed with a single plate even when the opening size is large, that is, the length of the waterproof door 1 is increased. If division is absolutely necessary, the existing product must have struts in the divided part, but the product of the present invention does not require external force on the divided part, so no struts are necessary. However, a one-touch type still water rubber is attached to the split part.
