Description

本発明は、止水部材に関する。 The present invention relates to a water blocking member.

従来、構造物の開口部に適用して当該構造物の内部への浸水を抑制する止水板（防水板、止水部材）が知られている。例えば、外開き式の扉体が構造物の開口部（ドア枠）に開閉可能に取り付けられている場合で、ドア枠に設けられた戸当りとドアの間、つまりドアの内側（屋内側）に止水板を挟持させて止水を行う防水ドア構造及び止水板が提案されている（特許文献１参照）。この防水ドア構造の止水板は、扁平な板材の外縁部の表裏にシールを備えたもので、戸当りと扉体との僅かな隙間に止水板を挟み込むことでシールを変形させて止水性能を向上させている。 Conventionally, a waterstop plate (waterproof plate, waterstop member) that is applied to an opening of a structure to prevent water from entering the structure is known. For example, when an outward-opening door body is attached to an opening (door frame) of a structure so as to be openable and closable, the space between the door stop and the door provided in the door frame, that is, the inside of the door (indoor side). A waterproof door structure and a waterstop plate that stop water by sandwiching the waterstop plate have been proposed (see Patent Document 1). The waterstop of this waterproof door structure is equipped with seals on the front and back of the outer edge of the flat plate material, and by sandwiching the waterstop in the slight gap between the door stop and the door body, the seal is deformed and stopped. The water performance is improved.

特開２０１４－２１８７９４号公報Japanese Unexamined Patent Publication No. 2014-218794

一般的な止水板は、ドアの外側（屋外側）にされるものが主流であり、上述したような屋内側に配置する止水板には、設置時や運搬時の取り扱いや機能に関して改善の余地があった。 Most of the general waterstops are on the outside (outdoor side) of the door, and the waterstops placed on the indoor side as described above have improved handling and functions during installation and transportation. There was room for.

本発明は、上記の事情に鑑みてなされたものであって、取り扱い性や機能性が改善されたシンプルな構造の止水部材を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a water blocking member having a simple structure with improved handleability and functionality.

上記目的を達成するために、本実施形態に係る止水部材は、構造物の開口部の一方側と他方側とを仕切る扉が閉じられた状態で、上記扉の下縁部および側縁部と、上記扉に対して上記一方側に位置され上記他方側を向いた戸当りと、の間の隙間に挿入され挟持可能な第一の部分と同一平面上で、かつ上記第一の部分より内側で、閉じられた状態の上記扉の上記一方側の下部と対向可能な第二の部分と、上記第一の部分の上記一方側のみで、かつ上記第一の部分の外縁部より内側の位置に上記外縁部に沿って設けられた第一のシール部材と、上記第一の部分の上記他方側と上記第二の部分の上記他方側の少なくとも一方に、閉じられた状態の上記扉の上記一方側と上記第二の部分の上記他方側との間に所定の隙間を形成するスペーサと、を備える。この構成によれば、例えば、第一の部材の他方側の面には、シール部材が存在しない。従って、第二の部材の他方側が、閉じられた状態の扉と対面した場合で、扉の他方側が浸水していた場合、扉の周囲から第二の部材と扉との間に意図的に水を浸入させることができる。つまり、扉の他方側（屋外側）の水圧と、扉の一方側（屋内側）と止水部材の第二の部分の他方側（屋外側）との間の隙間における水圧とをつり合わせる（打ち消し合う）ことができる。その結果、扉は、水中に浸かっている場合と同じ状態になり、扉に作用する力は水の抵抗のみになり、例えば、救出や非難の際に容易に扉を開くことができる。また、シール部材は、第一の部分の外縁部より内側の位置で外縁部に沿って設けられているので、止水部材の保管時に、シール部材は、他の物体との接触を回避し易く、劣化抑制ができる。また、スペーサを設けることにより、より広い隙間が形成され、扉の周囲を通過した水をより多く、また確実に扉と第二の部材の間に導入し易くすることができる。その結果、扉をより開け易くすることができる。 In order to achieve the above object, the water blocking member according to the present embodiment has a lower edge portion and a side edge portion of the door in a state where the door partitioning one side and the other side of the opening of the structure is closed. On the same plane as the first part that can be inserted and pinched in the gap between the door stop located on one side of the door and facing the other side, and from the first part. Inside, only the second part facing the lower part of the one side of the closed door and the one side of the first part, and inside the outer edge of the first part. A first sealing member provided at a position along the outer edge portion, and at least one of the other side of the first portion and the other side of the second portion, the door in a closed state. It is provided with a spacer that forms a predetermined gap between the one side and the other side of the second portion . According to this configuration, for example, there is no sealing member on the other side surface of the first member. Therefore, if the other side of the second member faces the closed door and the other side of the door is flooded, water is intentionally placed between the second member and the door from around the door. Can be infiltrated. That is, the water pressure on the other side (outdoor side) of the door is balanced with the water pressure in the gap between one side of the door (indoor side) and the other side (outdoor side) of the second part of the waterproof member (outdoor side). Can cancel each other out). As a result, the door is in the same state as if it were submerged in water, and the only force acting on the door is the resistance of the water, for example, the door can be easily opened during rescue or blame. Further, since the seal member is provided along the outer edge portion at a position inside the outer edge portion of the first portion, the seal member can easily avoid contact with other objects when the waterproof member is stored. , Deterioration can be suppressed. Further, by providing the spacer, a wider gap can be formed, more water can be passed around the door, and more water can be reliably introduced between the door and the second member. As a result, the door can be opened more easily.

上記目的を達成するために、本実施形態に係る止水構造は、構造物の開口部の一方側と他方側とを仕切る開閉可能な扉と、上記開口部に固定され、閉じられた状態の上記扉に対して上記一方側に位置し、上記他方において、上記扉の下縁部および側縁部に対向する戸当りを備えるドア枠と、閉じられた状態の上記扉と、上記戸当りと、の間の隙間に挿入され挟持可能な第一の部分と、上記第一の部分と同一平面上で、かつ上記第一の部分より内側で、閉じられた状態の上記扉の上記一方側の下部と対向可能な第二の部分と、上記第一の部分の上記一方側のみで、かつ上記第一の部分の外縁部より内側の位置に上記外縁部に沿って設けられた第一のシール部材と、上記第一の部分の上記他方側と上記第二の部分の上記他方側の少なくとも一方と、閉じられた状態の上記扉の上記一方側との間に、閉じられた状態の上記扉の上記一方側と上記第二の部分の上記他方側との間に所定の隙間を形成するスペーサと、を備える。この構成によれば、例えば、第一の部材の他方側の面には、シール部材が存在しない。従って、第二の部材の他方側が、閉じられた状態の扉と対面した場合で、扉の他方側が浸水していた場合、扉の周囲から第二の部材と扉との間に意図的に水を浸入させることができる。つまり、扉の他方側（屋外側）の水圧と、扉の一方側（屋内側）と止水部材の第二の部分の他方側（屋外側）との間の隙間における水圧とをつり合わせる（打ち消し合う）ことができる。その結果、扉は、水中に浸かっている場合と同じ状態になり、扉に作用する力は水の抵抗のみになり、例えば、救出や非難の際に容易に扉を開くことができる。また、シール部材は、第一の部分の外縁部より内側の位置で外縁部に沿って設けられているので、止水部材の保管時に、シール部材は、他の物体との接触を回避し易く、劣化抑制ができる。また、スペーサを介在させることにより、より広い隙間が形成され、扉の周囲を通過した水をより多く、また確実に扉と第二の部材の間に導入し易くすることができる。その結果、扉をより開け易くすることができる。 In order to achieve the above object, the waterproof structure according to the present embodiment has a door that can be opened and closed that separates one side and the other side of the opening of the structure, and a closed state that is fixed to the opening. A door frame located on one side of the door and having a door stop facing the lower edge portion and the side edge portion of the door, the closed door, and the door stop. The first part that can be inserted and pinched in the gap between the doors, and the one side of the door that is closed on the same plane as the first part and inside the first part. A first seal provided along the outer edge portion of the second portion facing the lower portion and only on one side of the first portion and at a position inside the outer edge portion of the first portion. The door in a closed state between the member and at least one of the other side of the first part and the other side of the second part and the one side of the door in the closed state. A spacer that forms a predetermined gap between the one side of the above and the other side of the second portion is provided. According to this configuration, for example, there is no sealing member on the other side surface of the first member. Therefore, if the other side of the second member faces the closed door and the other side of the door is flooded, water is intentionally placed between the second member and the door from around the door. Can be infiltrated. That is, the water pressure on the other side (outdoor side) of the door is balanced with the water pressure in the gap between one side of the door (indoor side) and the other side (outdoor side) of the second part of the waterproof member (outdoor side). Can cancel each other out). As a result, the door is in the same state as if it were submerged in water, and the only force acting on the door is the resistance of the water, for example, the door can be easily opened during rescue or blame. Further, since the seal member is provided along the outer edge portion at a position inside the outer edge portion of the first portion, the seal member can easily avoid contact with other objects when the waterproof member is stored. , Deterioration can be suppressed. Further, by interposing the spacer, a wider gap is formed, and more water can be surely introduced between the door and the second member. As a result, the door can be opened more easily.

また、本実施形態に係る止水部材の上記第一のシール部材は、例えば、上記戸当りの上記他方側に設けられた第二のシール部材と接触可能な位置に設けられ、上記扉が閉じられた状態で上記第一のシール部材と上記第二のシール部材のうち少なくとも一方が弾性変形するようにしてもよい。また、本実施形態に係る止水構造の上記戸当りは、上記他方側に第二のシール部材を備え、上記第一のシール部材は、例えば、第二のシール部材と接触可能な位置に設けられ、上記扉が閉じられた状態で上記第一のシール部材と上記第二のシール部材のうち少なくとも一方が弾性変形するようにしてもよい。この構成によれば、例えば、第二の部材の一方側（屋内側）への水の浸入をより抑制し易くすることができる。 Further, the first sealing member of the water blocking member according to the present embodiment is provided, for example, at a position where it can come into contact with the second sealing member provided on the other side of the door stop, and the door is closed. At least one of the first sealing member and the second sealing member may be elastically deformed in this state. Further, the door stop of the waterproof structure according to the present embodiment is provided with a second seal member on the other side, and the first seal member is provided, for example, at a position where it can come into contact with the second seal member. Therefore, at least one of the first sealing member and the second sealing member may be elastically deformed with the door closed. According to this configuration, for example, it is possible to more easily suppress the infiltration of water into one side (indoor side) of the second member.

また、本実施形態に係る止水部材または止水構造の上記第二の部分の上記一方側の面に、例えば、少なくとも一つの取っ手が設けられていてもよい。この構成によれば、例えば、止水部材の設置、運搬または止水構造の構築を容易に行うことができる。 Further , for example, at least one handle may be provided on the one-sided surface of the water-stopping member or the water-stopping structure according to the present embodiment. According to this configuration, for example, the water blocking member can be easily installed, transported, or the water blocking structure can be constructed.

FIG. 1 is a perspective view of the water blocking member 10 according to the first embodiment, and is a view in which the first portion 14 and the second portion 16 on the side facing the door 12 (see FIG. 3) are visible at the time of installation. Is. Further, FIG. 2 is a perspective view in which the first portion 14 and the second portion 16 on the side not facing the door 12 (indoor side) are visible when the waterproof member 10 is installed. FIG. 3 is a perspective view of a door frame 18 fixed to an opening of a structure (not shown) and a door 12 attached to the door frame 18. In the case of FIG. 3, the door 12 is, for example, an outward-opening type door that can partition one (for example, the indoor side) and the other (for example, the outdoor side) of the opening. The door frame 18 is formed with a support surface that is located on one side (indoor side) of the opening with respect to the door 12 and faces the other side (outdoor side) of the opening when the door 12 is closed. The support surface is formed, for example, on the lower frame portion and the vertical frame portion of the door frame 18. In the lower frame portion of the door frame 18, for example, a lower door contact 18a facing the lower edge portion 12a of the door 12 when the door 12 is closed is formed as a support surface. Further, in the vertical frame portion of the door frame 18, a vertical door contact 18b with which the side edge portions 12b of the door 12 face each other when the door 12 is closed is formed as a support surface. In the case of FIG. 3, only the vertical door 18b on the side where the hinge connecting the door 12 and the door frame 18 is provided is shown, and when the door frame 18 is closed, the vertical door on the side close to the knob 20 is shown. The hit 18b is not shown. When the door 12 is closed, a gap (first gap A, which will be described later) is formed between each door stop and the door 12. In FIG. 3, for example, a packing (seal member) (not shown) is attached to the lower door stop 18a, the left and right vertical door stops 18b, and the upper door stop (not shown) formed on the upper part of the door frame 18. You may. Then, when the door 12 is closed, the door 12 comes into contact with the packing or the packing is crushed to reduce the first gap A formed between each door stop and the door 12 (first). It may be possible to improve the airtightness in the room by sealing the gap A in the room.

図１、図２に戻り、止水部材１０は、第一の部分１４と第二の部分１６とを備える。第一の部分１４は、止水部材１０を構造物の開口部、すなわちドア枠１８に設置する場合に、各戸当りと扉１２との間に形成される第一の隙間Ａに挿入される部分である。具体的には、第一の部分１４のうちドア枠１８の幅方向に沿って形成された下部挿入部１４ａは、扉１２が閉じられることにより、下部戸当り１８ａと下縁部１２ａ（図３参照）とによって挟持される。同様に、第一の部分１４のうちドア枠１８の縦方向に沿って形成された縦挿入部１４ｂは、扉１２が閉じられることにより、縦戸当り１８ｂと側縁部１２ｂとによって挟持される。 Returning to FIGS. 1 and 2, the water blocking member 10 includes a first portion 14 and a second portion 16. The first portion 14 is a portion inserted into the first gap A formed between each door stop and the door 12 when the water blocking member 10 is installed in the opening of the structure, that is, the door frame 18. Is. Specifically, of the first portion 14, the lower insertion portion 14a formed along the width direction of the door frame 18 has a lower door contact 18a and a lower edge portion 12a (FIG. 3) when the door 12 is closed. See) and sandwiched by. Similarly, of the first portion 14, the vertical insertion portion 14b formed along the vertical direction of the door frame 18 is sandwiched between the vertical door contact 18b and the side edge portion 12b when the door 12 is closed. ..

第二の部分１６は、第一の部分１４よりも扉１２の周縁部から一方側（屋内側）に離れて位置される。つまり、扉１２の周縁部である下縁部１２ａ及び側縁部１２ｂに挟持される第一の部分１４より第二の部分１６は屋内側に位置される。第二の部分１６は、扉１２の下部（例えば扉１２の下端から６０ｃｍ）の一方側（屋内側）で、第一の隙間Ａよりも大きい第二の隙間Ｂをあけて面するように構成されている。止水部材１０は、図１に示すように、扁平の第二の部分１６の周縁部のうちドア枠１８の幅方向に沿って、第二の部分１６と直交するように幅方向縁部１６ａに連設された底壁部２２ａと、ドア枠１８の縦方向に沿って、第二の部分１６と直交するように縦方向縁部１６ｂに連設された側壁部２２ｂとを備える。このように、第二の部分１６及びそれに直交する底壁部２２ａと側壁部２２ｂとによって、止水部材１０がドア枠１８に設置されて扉１２と対面したときに第二の隙間Ｂが形成される。そして、底壁部２２ａの一端側に下部挿入部１４ａが縦方向に突出するように接続されている。つまり、下部挿入部１４ａは、底壁部２２ａにおいて第二の部分１６から遠い側に形成されたフランジである。同様に、側壁部２２ｂの一端側に縦挿入部１４ｂが幅方向に突出するように接続されている。つまり、縦挿入部１４ｂは、側壁部２２ｂにおいて第二の部分１６から遠い側に形成されたフランジである。つまり、このフランジ（下部挿入部１４ａ及び縦挿入部１４ｂ）が第一の隙間Ａに挿入される。 The second portion 16 is located closer to one side (indoor side) from the peripheral edge of the door 12 than the first portion 14. That is, the second portion 16 from the first portion 14 sandwiched between the lower edge portion 12a and the side edge portion 12b, which are the peripheral edges of the door 12, is located on the indoor side. The second portion 16 is configured to face one side (indoor side) of the lower part of the door 12 (for example, 60 cm from the lower end of the door 12) with a second gap B larger than the first gap A. Has been done. As shown in FIG. 1, the water blocking member 10 has a widthwise edge portion 16a so as to be orthogonal to the second portion 16 along the width direction of the door frame 18 in the peripheral edge portion of the flat second portion 16. A bottom wall portion 22a connected to the door frame 18 and a side wall portion 22b connected to the vertical edge portion 16b so as to be orthogonal to the second portion 16 along the vertical direction of the door frame 18 are provided. In this way, the second portion 16 and the bottom wall portion 22a and the side wall portion 22b orthogonal to the second portion 16 form a second gap B when the water blocking member 10 is installed on the door frame 18 and faces the door 12. Will be done. The lower insertion portion 14a is connected to one end side of the bottom wall portion 22a so as to project in the vertical direction. That is, the lower insertion portion 14a is a flange formed on the bottom wall portion 22a on the side far from the second portion 16. Similarly, the vertical insertion portion 14b is connected to one end side of the side wall portion 22b so as to project in the width direction. That is, the vertical insertion portion 14b is a flange formed on the side wall portion 22b on the side far from the second portion 16. That is, this flange (lower insertion portion 14a and vertical insertion portion 14b) is inserted into the first gap A.

また、下部挿入部１４ａの一方側及び縦挿入部１４ｂの一方側、すなわちドア枠１８に設置した場合に屋内側に向く側には、シール部材２４が固定されている。シール部材２４については、後述するが、例えば、柔軟性（可撓性、弾性）を有する材料、例えば合成樹脂材料（ゴム、エラストマ、柔軟性樹脂等）で形成されている。例えば、独立発泡型の気泡を多く含むゴム材料で、温度変化に対する劣化が少なく、耐摩耗性のある材料で構成することが望ましい。一例として、エプトシーラー（登録商標）等を利用することができる。 Further, the seal member 24 is fixed to one side of the lower insertion portion 14a and one side of the vertical insertion portion 14b, that is, the side facing the indoor side when installed in the door frame 18. The seal member 24 will be described later, but is made of, for example, a material having flexibility (flexibility, elasticity), for example, a synthetic resin material (rubber, elastomer, flexible resin, etc.). For example, it is desirable to use a rubber material containing a large amount of independent foam type bubbles, which is less deteriorated by temperature changes and has wear resistance. As an example, Eptsealer (registered trademark) and the like can be used.

また、止水部材１０は、第二の部分１６において、底壁部２２ａから縦枠（高さ）方向に離れた位置に止水部材１０を運搬するときやドア枠１８に設置する際に手指を挿入して持ち上げる開口部２６が例えば左右２カ所に形成されている。止水部材１０が扉１２に対面したときでも、第二の隙間Ｂが存在するため開口部２６に利用者は手指を挿入し易く、容易に止水部材１０を運搬したり、ドア枠１８に設置する際に位置決めすることができる。なお、開口部２６に代えて、または加えて例えば第二の部分１６の一方側（屋内側）や第二の部分１６の上端部（上面部）に取っ手を設けてもよい。また、止水部材１０にストラップ等を付けてもよく、同様の効果を得ることができる。 Further, the waterproof member 10 is a finger when transporting the waterproof member 10 to a position separated from the bottom wall portion 22a in the vertical frame (height) direction in the second portion 16 or when installing the waterproof member 10 on the door frame 18. The openings 26 for inserting and lifting the are formed in, for example, two places on the left and right. Even when the water stop member 10 faces the door 12, the presence of the second gap B makes it easy for the user to insert a finger into the opening 26, so that the water stop member 10 can be easily carried or the door frame 18 can be used. It can be positioned when it is installed. In addition, instead of the opening 26, or in addition, for example, a handle may be provided on one side (indoor side) of the second portion 16 or the upper end portion (upper surface portion) of the second portion 16. Further, a strap or the like may be attached to the water blocking member 10, and the same effect can be obtained.

止水部材１０は、例えば、扁平な金属板（例えば、鉄板やステンレス板）を曲げ加工するとともに、適宜溶接等を行うことで形成することができる。また、止水部材１０は、樹脂（例えば、繊維強化プラスチック等）を用いて成形してもよい。 The water blocking member 10 can be formed, for example, by bending a flat metal plate (for example, an iron plate or a stainless steel plate) and appropriately welding or the like. Further, the water blocking member 10 may be molded using a resin (for example, fiber reinforced plastic or the like).

このように構成される止水部材１０の設置例を図４～図６を用いて説明する。図４は、止水部材１０の設置状態を示す図であり、開口部の他方側（屋外側）から見た場合の斜視図である。図５は、止水部材１０の設置状態を示す横断面図である。また、図６は、止水部材１０の設置状態を示す縦断面図である。 An installation example of the water blocking member 10 configured in this way will be described with reference to FIGS. 4 to 6. FIG. 4 is a view showing an installed state of the water blocking member 10, and is a perspective view when viewed from the other side (outdoor side) of the opening. FIG. 5 is a cross-sectional view showing an installed state of the water blocking member 10. Further, FIG. 6 is a vertical sectional view showing an installed state of the water blocking member 10.

図４に示すように、止水部材１０は、扉１２が開かれた状態（屋外側に外開きの状態）のときに、ドア枠１８の開口部に設置される。すなわち、扉１２が閉じられたときに当該扉１２の下縁部１２ａと下部戸当り１８ａとの間及び側縁部１２ｂと縦戸当り１８ｂとの間に形成される第一の隙間Ａに第一の部分１４が挿入されるように設置される。具体的には、止水部材１０の第一の部分１４のうち下部挿入部１４ａが下部戸当り１８ａに当接するように挿入され、縦挿入部１４ｂが縦戸当り１８ｂに当接するように挿入される。この場合、止水部材１０は、第一の部分１４が第二の部分１６より屋外側になるような姿勢（向き）で支持されて、屋外側から下部戸当り１８ａ、縦戸当り１８ｂに当接するような姿勢で設置される。前述したように、第一の部分１４より第二の部分１６が屋内側に位置するので、止水部材１０の重心が当該止水部材１０をドア枠１８に寄りかからせるような位置に存在するので、止水部材１０の設置時に止水部材１０は自立し易く、屋外側に倒れにくくなる。その結果、設置準備時の取り扱いが容易になる。また、止水部材１０が設置し易くなり、設置機能性が改善（向上）される。 As shown in FIG. 4, the water blocking member 10 is installed in the opening of the door frame 18 when the door 12 is open (outside open to the outdoor side). That is, when the door 12 is closed, the first gap A formed between the lower edge portion 12a of the door 12 and the lower door stop 18a and between the side edge portion 12b and the vertical door stop 18b is the first. It is installed so that one part 14 is inserted. Specifically, of the first portion 14 of the water blocking member 10, the lower insertion portion 14a is inserted so as to abut against the lower door stop 18a, and the vertical insertion portion 14b is inserted so as to abut against the vertical door stop 18b. To. In this case, the water blocking member 10 is supported in a posture (orientation) such that the first portion 14 is on the outdoor side of the second portion 16 and hits the lower door contact 18a and the vertical door stop 18b from the outdoor side. It is installed in a contacting posture. As described above, since the second portion 16 is located indoors from the first portion 14, the center of gravity of the waterproof member 10 is located at a position where the waterproof member 10 leans toward the door frame 18. Therefore, when the water blocking member 10 is installed, the water blocking member 10 is easy to stand on its own and is less likely to fall to the outdoor side. As a result, it becomes easy to handle when preparing for installation. In addition, the water blocking member 10 can be easily installed, and the installation functionality is improved (improved).

第一の隙間Ａに止水部材１０を挿入した後、図５、図６に示すように、扉１２を閉じる。扉１２を閉じることにより、下縁部１２ａが下部戸当り１８ａに対面し、側縁部１２ｂが縦戸当り１８ｂに対面する。前述したように、下部戸当り１８ａ、縦戸当り１８ｂ、上部戸当り１８ｃには、パッキン２８（シール部材）が配置され、扉１２が閉じられたときに、パッキン２８に接触する、またはパッキン２８が変形するようになっている。図６の場合、例えば、扉１２の上縁部１２ｃが上部戸当り１８ｃに配置されたパッキン２８を変形させて、気密性の向上（すきま風等の侵入抑制）を行っている。下縁部１２ａおよび側縁部１２ｂも同様にパッキン２８を変形させて気密性の向上に寄与できる。 After inserting the water blocking member 10 into the first gap A, the door 12 is closed as shown in FIGS. 5 and 6. By closing the door 12, the lower edge portion 12a faces the lower door contact 18a, and the side edge portion 12b faces the vertical door contact 18b. As described above, the packing 28 (seal member) is arranged at the lower door stop 18a, the vertical door stop 18b, and the upper door stop 18c, and when the door 12 is closed, it comes into contact with the packing 28 or the packing 28. Is designed to be deformed. In the case of FIG. 6, for example, the upper edge portion 12c of the door 12 deforms the packing 28 arranged at the upper door contact 18c to improve the airtightness (suppress the intrusion of drafts and the like). The lower edge portion 12a and the side edge portion 12b can also deform the packing 28 to contribute to the improvement of airtightness.

扉１２の下部Ｃにおける第一の隙間Ａは、止水部材１０の第一の部分１４が挿入されるとパッキン２８が更に変形して（潰れて）第一の隙間Ａにおける止水部材１０の第一の部分１４の挿入状態を許容する。図５に示すように、縦挿入部１４ｂに固定されたシール部材２４が縦戸当り１８ｂに固定されたパッキン２８に当接して、互いにまたは一方が弾性変形する。同様に、図６に示すように、下部挿入部１４ａに固定されたシール部材２４が下部戸当り１８ａに固定されたパッキン２８に当接して、互いにまたは一方が弾性変形する。その結果、パッキン２８は、止水部材１０の第一の部分１４が介在しない場合に比べて大きく変形する。そして、ドア枠１８、第一の部分１４（止水部材１０）、扉１２の三者の密着性（水密性）が向上される。つまり、仮に扉１２の他方側（屋外側）で冠水した場合でも、シール部材２４及びパッキン２８により止水部材１０の一方側（屋内側）がシール（止水）されるので、止水部材１０の周囲から屋内側へ水が浸入することが抑制できる。 In the first gap A in the lower portion C of the door 12, the packing 28 is further deformed (crushed) when the first portion 14 of the water blocking member 10 is inserted, and the water stopping member 10 in the first gap A is further deformed (crushed). The insertion state of the first portion 14 is allowed. As shown in FIG. 5, the seal member 24 fixed to the vertical insertion portion 14b abuts on the packing 28 fixed to the vertical door stop 18b, and one or the other is elastically deformed. Similarly, as shown in FIG. 6, the seal member 24 fixed to the lower insertion portion 14a abuts on the packing 28 fixed to the lower door stop 18a, and one or the other is elastically deformed. As a result, the packing 28 is greatly deformed as compared with the case where the first portion 14 of the water blocking member 10 does not intervene. Then, the adhesion (watertightness) of the door frame 18, the first portion 14 (water blocking member 10), and the door 12 is improved. That is, even if the other side (outdoor side) of the door 12 is flooded, the sealing member 24 and the packing 28 seal (stop water) one side (indoor side) of the water blocking member 10, so that the water blocking member 10 It is possible to prevent water from entering from the surrounding area to the indoor side.

なお、図５、図６の例では、シール部材２４及びパッキン２８を用いる場合を示したが、いずれか一方、または両方を省略してもよい。例えば、構造物の仕様によっては、ドア枠１８側のパッキン２８がない場合がある。このような場合は、ドア枠１８と第一の部分１４との間のシールをシール部材２４のみで行うようにしてもよい。この場合も、第一の隙間Ａに、第一の部分１４及びシール部材２４が介在する（挟み込まれる）ことにより、ドア枠１８、第一の部分１４（止水部材１０）、扉１２の三者の密着性（水密性）を向上させることができる。逆に、例えば、第一の部分１４のシール部材２４を省略してもよい。この場合、ドア枠１８のパッキン２８に直接第一の部分１４を接触させることになる。パッキン２８は第一の部分１４が介在する場合、第一の部分１４が介在しない場合に比べてより圧縮させられるので、ドア枠１８、第一の部分１４（止水部材１０）、扉１２の三者の密着性（水密性）を向上させることができる。また、扉１２は、一般的に金属等で形成されたフレームの表面を薄板材で覆うことによって構成されている。したがって、扉１２は厚み方向に僅かに弾性変形可能である場合がある。このような場合は、シール部材２４及びパッキン２８の両方を省略することができる。この場合、止水部材１０が設置されない場合の第一の隙間Ａの寸法より僅かに第一の部分１４の厚み寸法を大きくする。その結果、扉１２の弾性変形を利用して、ドア枠１８と扉１２とによって直接第一の部分１４を挟持する。この場合もドア枠１８、第一の部分１４（止水部材１０）、扉１２の三者の密着性（水密性）を向上させることができる。 In the examples of FIGS. 5 and 6, the case where the seal member 24 and the packing 28 are used is shown, but either one or both may be omitted. For example, depending on the specifications of the structure, the packing 28 on the door frame 18 side may not be provided. In such a case, the sealing between the door frame 18 and the first portion 14 may be performed only by the sealing member 24. Also in this case, the door frame 18, the first portion 14 (water blocking member 10), and the door 12 are formed by interposing (sandwiching) the first portion 14 and the sealing member 24 in the first gap A. It is possible to improve the adhesion (watertightness) of a person. Conversely, for example, the seal member 24 of the first portion 14 may be omitted. In this case, the first portion 14 is brought into direct contact with the packing 28 of the door frame 18. When the packing 28 is interposed, the packing 28 is more compressed than when the first portion 14 is intervened. Therefore, the door frame 18, the first portion 14 (water blocking member 10), and the door 12 are packed. It is possible to improve the adhesion (watertightness) of the three parties. Further, the door 12 is generally configured by covering the surface of a frame made of metal or the like with a thin plate material. Therefore, the door 12 may be slightly elastically deformable in the thickness direction. In such a case, both the sealing member 24 and the packing 28 can be omitted. In this case, the thickness dimension of the first portion 14 is slightly larger than the dimension of the first gap A when the water blocking member 10 is not installed. As a result, the first portion 14 is directly sandwiched between the door frame 18 and the door 12 by utilizing the elastic deformation of the door 12. Also in this case, the adhesion (watertightness) of the door frame 18, the first portion 14 (water blocking member 10), and the door 12 can be improved.

なお、止水部材１０の第二の部分１６は、扉１２の幅方向で構造物（ドア枠１８）に接する位置まで延設してもよい。例えば、図５に示すように、止水部材１０の幅Ｗ１（対向する側壁部２２ｂの外面間距離）は、ドア枠１８（開口部）の開口幅Ｗ０より僅かに大きくすることができる。つまり、ドア枠１８に止水部材１０を設置する場合、止水部材１０を僅かに幅方向に圧縮させながら圧入状態で設置するようにしてもよい。このように、圧入状態で設置することにより、止水部材１０の設置姿勢が安定する。また、後述するが、冠水状態で扉１２を開けて屋外に出る場合でも、止水部材１０がドア枠１８から外れ難くなる。つまり、冠水時に扉１２を開けた場合でも屋内側に水が浸入することが抑制され、利用者に安心感を与えやすくなる。なお、他の実施例では、止水部材１０の幅Ｗ１をドア枠１８の開口幅Ｗ０と同等または開口幅Ｗ０より小さくしてもよい。この場合、ドア枠１８の所定位置に止水部材１０を設置し易くなり（単に置くだけになり）、固定はもっぱら扉１２とドア枠１８とによる挟持により行われる。この場合、止水部材１０の設置及び取り外し時の作業が容易になるというメリットがある。 The second portion 16 of the water blocking member 10 may be extended to a position in contact with the structure (door frame 18) in the width direction of the door 12. For example, as shown in FIG. 5, the width W1 of the water blocking member 10 (distance between the outer surfaces of the facing side wall portions 22b) can be slightly larger than the opening width W0 of the door frame 18 (opening portion). That is, when the water blocking member 10 is installed on the door frame 18, the water blocking member 10 may be installed in a press-fitted state while being slightly compressed in the width direction. By installing in the press-fitted state in this way, the installation posture of the water blocking member 10 is stabilized. Further, as will be described later, even when the door 12 is opened and the vehicle goes outdoors in a flooded state, the water blocking member 10 does not easily come off from the door frame 18. That is, even if the door 12 is opened at the time of flooding, water is suppressed from entering the indoor side, and it becomes easy to give a sense of security to the user. In another embodiment, the width W1 of the water blocking member 10 may be equal to or smaller than the opening width W0 of the door frame 18. In this case, the water blocking member 10 can be easily installed at a predetermined position of the door frame 18 (simply placed), and the fixing is performed exclusively by the door 12 and the door frame 18. In this case, there is an advantage that the work at the time of installing and removing the water blocking member 10 becomes easy.

図７は、止水部材１０のシール部材２４の固定位置を示す斜視図である。シール部材２４は、第一の部分１４（下部挿入部１４ａ、縦挿入部１４ｂ）の一方側（屋内側）のみに設けられる。また、シール部材２４は、第一の部分１４の外縁部１４ｃから離れた位置に固定されている。つまり、下部挿入部１４ａに固定されるシール部材２４は、外縁部１４ｃより底壁部２２ａに近い位置に固定されている。同様に、縦挿入部１４ｂに固定されるシール部材２４は、外縁部１４ｃより側壁部２２ｂに近い位置に固定されている。このように、シール部材２４を外縁部１４ｃから離れた位置に固定することにより、例えば止水部材１０の保管時に、シール部材２４が他の物体（例えば床や壁）と接触する可能性が低減できる。その結果、保管時のシール部材２４の劣化を軽減できる。例えばシール部材２４が保管時に壁や床に接触して長時間圧縮変形した状態が継続され弾性力（復元力）が低下してしまうことが抑制できる。なお、止水部材１０を保管する場合は、図７に示すように下部挿入部１４ａが上方になるように、設置時とは逆さまにして保管することが望ましい。また、この場合、第一の部分１４に対して第二の部分１６が離れた位置に存在するので、立て掛けやすく保管しやすいというメリットもある。なお、図７の場合、方形（平帯状）のシール部材２４を第一の部分１４（下部挿入部１４ａ、縦挿入部１４ｂ）に配置（固定）する例を示した。別の実施例においては、シール部材２４が底壁部２２ａや側壁部２２ｂまで跨いで配置（固定）されるようにしてもよい。例えば、断面形状が略Ｌ字形状のシール部材２４を用いて、下部挿入部１４ａと底壁部２２ａとの両方を跨ぎシールするようにしてもよい。同様に、縦挿入部１４ｂと側壁部２２ｂとの両方を跨ぎシールするようにしてもよい。この場合、ドア枠１８（戸当り）との密着性が更に増し、シール性をより向上させることができる。なお、下部挿入部１４ａと底壁部２２ａに別々のシール部材を配置（固定）してもよい。また、一方を止水部材１０側、他方をドア枠１８側に配置するようにしてもよく、同様の効果を得ることができる。 FIG. 7 is a perspective view showing a fixed position of the seal member 24 of the water blocking member 10. The seal member 24 is provided only on one side (indoor side) of the first portion 14 (lower insertion portion 14a, vertical insertion portion 14b). Further, the seal member 24 is fixed at a position away from the outer edge portion 14c of the first portion 14. That is, the seal member 24 fixed to the lower insertion portion 14a is fixed at a position closer to the bottom wall portion 22a than the outer edge portion 14c. Similarly, the seal member 24 fixed to the vertical insertion portion 14b is fixed at a position closer to the side wall portion 22b than the outer edge portion 14c. By fixing the seal member 24 at a position away from the outer edge portion 14c in this way, the possibility that the seal member 24 comes into contact with another object (for example, a floor or a wall) can be reduced, for example, when the water stop member 10 is stored. .. As a result, deterioration of the seal member 24 during storage can be reduced. For example, it is possible to prevent the sealing member 24 from coming into contact with the wall or floor during storage and being continuously compressed and deformed for a long time to reduce the elastic force (restoring force). When storing the water blocking member 10, it is desirable to store it upside down from the time of installation so that the lower insertion portion 14a faces upward as shown in FIG. 7. Further, in this case, since the second portion 16 is located at a position separated from the first portion 14, there is an advantage that it is easy to lean against and store. In the case of FIG. 7, an example in which the square (flat band-shaped) sealing member 24 is arranged (fixed) in the first portion 14 (lower insertion portion 14a, vertical insertion portion 14b) is shown. In another embodiment, the seal member 24 may be arranged (fixed) so as to straddle (fix) the bottom wall portion 22a and the side wall portion 22b. For example, a sealing member 24 having a substantially L-shaped cross section may be used to straddle and seal both the lower insertion portion 14a and the bottom wall portion 22a. Similarly, both the vertical insertion portion 14b and the side wall portion 22b may be straddled and sealed. In this case, the adhesion to the door frame 18 (door contact) is further increased, and the sealing property can be further improved. Separate sealing members may be arranged (fixed) on the lower insertion portion 14a and the bottom wall portion 22a. Further, one may be arranged on the water blocking member 10 side and the other on the door frame 18 side, and the same effect can be obtained.

ところで、扉１２が閉じられた状態で、扉１２の他方側（屋外側）が冠水した場合、扉１２の屋外側に水圧が作用して扉１２が容易に開けない場合があるという問題がある。例えば、屋外の冠水が初期の段階では、構造物内（屋内）に避難している場合が多い。一方、冠水が所定値を越えた場合には、より安全な避難場所に移動することが望ましい場合がある。そこで、第１実施形態の止水部材１０は、扉１２が閉じた状態で、かつ止水部材１０がドア枠１８に設置された状態で、扉１２の他方側（屋外側）から水（冠水した水）を止水部材１０と扉１２との間に導入できるように、第二の部分１６が第二の隙間Ｂを形成している。 By the way, when the other side (outdoor side) of the door 12 is flooded with the door 12 closed, there is a problem that the door 12 may not be easily opened due to water pressure acting on the outdoor side of the door 12. .. For example, in the early stages of outdoor flooding, there are many cases of evacuation inside the structure (indoors). On the other hand, if the flooding exceeds a predetermined value, it may be desirable to move to a safer evacuation site. Therefore, in the water stop member 10 of the first embodiment, with the door 12 closed and the water stop member 10 installed on the door frame 18, water (submerged) from the other side (outdoor side) of the door 12. The second portion 16 forms a second gap B so that the water can be introduced between the water blocking member 10 and the door 12.

扉１２は、ドア枠１８に対して開閉自在とするために、一般的にドア枠１８と扉１２の下面部１２ｄ、側面部１２ｅ、上面部１２ｆとの間には隙間が形成されている。例えば、図５に示すように、側面部１２ｅとドア枠１８との間には、縦隙間Ｄが形成されている。同様に、図６に示すように、下面部１２ｄとドア枠１８との間には、下部隙間Ｅが形成されている。そのため、冠水した水の一部は、ドア枠１８と扉１２との間を通過することができる。図５、図６に示すように、扉１２の下縁部１２ａと下部挿入部１４ａとが当接し、側縁部１２ｂと縦挿入部１４ｂとが当接するが、扉１２の表面は完全な平面ではなく、凹凸が存在する場合がある。例えば、意匠性の向上のために縦縞等のような凹凸の模様が付与されている場合がある。また、第１実施形態の止水部材１０の場合、下縁部１２ａと下部挿入部１４ａとの間や側縁部１２ｂと縦挿入部１４ｂとの間にはシール部材を介在させない。そのため、図８に示すように下部隙間Ｅ（及び縦隙間Ｄ）から浸入した水は、下縁部１２ａと下部挿入部１４ａとの間（及び側縁部１２ｂと縦挿入部１４ｂとの間）を通り、矢印Ｑで示すように、止水部材１０の第二の部分１６、底壁部２２ａ、側壁部２２ｂ及び扉１２の一方側の面（屋内側の面）で囲まれた空間（第二の隙間Ｂ）に意図的に浸入させられる。 In order to make the door 12 openable and closable with respect to the door frame 18, a gap is generally formed between the door frame 18 and the lower surface portion 12d, the side surface portion 12e, and the upper surface portion 12f of the door 12. For example, as shown in FIG. 5, a vertical gap D is formed between the side surface portion 12e and the door frame 18. Similarly, as shown in FIG. 6, a lower gap E is formed between the lower surface portion 12d and the door frame 18. Therefore, a part of the flooded water can pass between the door frame 18 and the door 12. As shown in FIGS. 5 and 6, the lower edge portion 12a of the door 12 and the lower insertion portion 14a are in contact with each other, and the side edge portion 12b and the vertical insertion portion 14b are in contact with each other, but the surface of the door 12 is completely flat. Instead, there may be irregularities. For example, an uneven pattern such as vertical stripes may be added to improve the design. Further, in the case of the water blocking member 10 of the first embodiment, no sealing member is interposed between the lower edge portion 12a and the lower insertion portion 14a or between the side edge portion 12b and the vertical insertion portion 14b. Therefore, as shown in FIG. 8, the water that has entered from the lower gap E (and the vertical gap D) is between the lower edge portion 12a and the lower insertion portion 14a (and between the side edge portion 12b and the vertical insertion portion 14b). As shown by the arrow Q, the space surrounded by the second portion 16, the bottom wall portion 22a, the side wall portion 22b, and the door 12 on one side (indoor side surface) of the water blocking member 10. It is intentionally infiltrated into the second gap B).

この場合、下部隙間Ｅ（及び縦隙間Ｄ）を通過して浸入する水の流れは、扉１２の他方側（屋外側）の水頭高さと扉１２の一方側（屋内側）の第二の隙間Ｂにおける水頭高さとが同じになった時点で停止する。この場合、扉１２の他方側（屋外側）の水圧Ｐ１と扉１２の一方側（屋内側）の第二の隙間Ｂにおける水圧Ｐ２とがつり合う（打ち消し合う）。その結果、扉１２は、水中に浸かっている場合と同じ状態になり、扉１２に作用する力は水の抵抗のみになり容易に開くことができる。その結果、構造物の屋内側にいた利用者は、扉１２を開き屋外に移動することが可能になる。なお、この場合もドア枠１８と止水部材１０の第一の部分１４との水密状態は、シール部材２４やパッキン２８により維持されるので、水が屋内側に浸入してしまうことが抑制できる。また、扉１２が開かれた場合、それまでドア枠１８に対して第一の部分１４を押圧していた力が解放されるが、第一の部分１４及び第二の部分１６の他方側（屋外側）は、水圧が作用してドア枠１８側（下部戸当り１８ａ側、縦戸当り１８ｂ側）に押圧されるので、第一の部分１４の付勢状態が維持される。また、図５に示すように、止水部材１０の幅Ｗ１（対向する側壁部２２ｂの外面間距離）をドア枠１８（開口部）の開口幅Ｗ０より僅かに大きくすることにより、扉１２を開いた場合でも止水部材１０をドア枠１８に対して自立させやすくなり、水圧により倒れたり、止水可能な姿勢が損なわれないようにすることができる。 In this case, the flow of water that enters through the lower gap E (and the vertical gap D) is the head height on the other side (outdoor side) of the door 12 and the second gap on one side (indoor side) of the door 12. It stops when the height of the head in B becomes the same. In this case, the water pressure P1 on the other side (outdoor side) of the door 12 and the water pressure P2 in the second gap B on one side (indoor side) of the door 12 are balanced (cancelled). As a result, the door 12 is in the same state as when it is immersed in water, and the force acting on the door 12 is only the resistance of water and can be easily opened. As a result, the user who was on the indoor side of the structure can open the door 12 and move to the outside. In this case as well, the watertight state between the door frame 18 and the first portion 14 of the water blocking member 10 is maintained by the sealing member 24 and the packing 28, so that it is possible to prevent water from entering the indoor side. .. Further, when the door 12 is opened, the force that has previously pressed the first portion 14 against the door frame 18 is released, but the other side of the first portion 14 and the second portion 16 ( The outdoor side) is pressed against the door frame 18 side (lower door contact 18a side, vertical door contact 18b side) by the action of water pressure, so that the urging state of the first portion 14 is maintained. Further, as shown in FIG. 5, the door 12 is made slightly larger than the opening width W0 of the door frame 18 (opening) by making the width W1 of the water blocking member 10 (distance between the outer surfaces of the facing side wall portions 22b) slightly larger than the opening width W0 of the door frame 18 (opening). Even when the water blocking member 10 is opened, the water blocking member 10 can be easily made to stand on the door frame 18 so as not to fall down due to water pressure or to impair the posture in which the water can be stopped.

図９は、止水部材１０の変形例を示す斜視図である。前述したように、止水部材１０は、意図的に第二の隙間Ｂに水を導入するが、その浸入経路は下縁部１２ａと下部挿入部１４ａとの間に形成される隙間や側縁部１２ｂと縦挿入部１４ｂとの間に形成される隙間である。そこで、図９に示すように、第一の部分１４（下部挿入部１４ａ、縦挿入部１４ｂ）に連通溝３０を形成して、より積極的に第二の部分１６と扉１２の一方との間の第二の隙間Ｂに水が導入できるようにしている。この場合、扉１２の他方側（屋外側）の水頭高さの上昇速度と扉１２の一方側（屋内側）の第二の隙間Ｂにおける水頭高さの上昇速度の差を低減することができる。その結果、扉１２を開けようとしたときに、第二の隙間Ｂにおける水頭高さの上昇を待たなければならないという不都合の発生を低減できる。なお、図９の場合、下部挿入部１４ａと縦挿入部１４ｂの両方に連通溝３０が形成されている例を示しているが、連通溝３０は、下部挿入部１４ａと縦挿入部１４ｂのいずれか一方でもよく、同様の効果を得ることができる。なお、連通溝３０は、下部挿入部１４ａに形成することにより冠水の初期の段階から第二の隙間Ｂに水の導入ができるので、扉１２の他方側と一方側の水頭高さの差の発生が抑制し易い。 FIG. 9 is a perspective view showing a modified example of the water blocking member 10. As described above, the water blocking member 10 intentionally introduces water into the second gap B, but the intrusion path is a gap or a side edge formed between the lower edge portion 12a and the lower insertion portion 14a. It is a gap formed between the portion 12b and the vertical insertion portion 14b. Therefore, as shown in FIG. 9, a communication groove 30 is formed in the first portion 14 (lower insertion portion 14a, vertical insertion portion 14b), and the second portion 16 and one of the doors 12 are more positively formed. Water can be introduced into the second gap B between them. In this case, it is possible to reduce the difference between the rising speed of the head height on the other side (outdoor side) of the door 12 and the rising speed of the head height in the second gap B on one side (indoor side) of the door 12. .. As a result, it is possible to reduce the occurrence of the inconvenience of having to wait for the head height to rise in the second gap B when the door 12 is to be opened. Note that FIG. 9 shows an example in which the communication groove 30 is formed in both the lower insertion portion 14a and the vertical insertion portion 14b, but the communication groove 30 is either the lower insertion portion 14a or the vertical insertion portion 14b. On the other hand, the same effect can be obtained. By forming the communication groove 30 in the lower insertion portion 14a, water can be introduced into the second gap B from the initial stage of flooding, so that the difference in head height between the other side and one side of the door 12 can be seen. It is easy to suppress the occurrence.

止水部材１０の幅は、止水部材１０を設置する構造物（開口部）の仕様によって決定され、止水部材１０の高さは、冠水の特性に応じて決定することが望ましい。例えば、扉１２の幅が広ければ、それに応じて止水部材１０も幅の広いものが選択される。また、止水部材１０の高さは、過去に発生した冠水の高さに応じて、それに余裕値を加えた高さのものを選択すればよい。また、扉１２の一方側（屋内側）には、様々な突起物が存在する場合がある。例えば、図１０、図１１に示すように、一方側（屋内側）に郵便ポスト３２を備える扉１２がある。このような扉１２に止水部材１０を適用する場合、止水部材１０の高さは、郵便ポスト３２と干渉しない（非干渉となる）ように選択される。図１０は、標準的な大きさ（高さ）の止水部材１０（例えば、５０ｃｍ程度までの冠水が予想される地域で利用可能な止水部材１０）の設置例を示す図である。図１０は、第二の隙間Ｂが郵便ポスト３２の厚みより薄く、高さが郵便ポスト３２の下端位置より低い止水部材１０が設置されている例である。このように、止水部材１０は必要最小限の大きさとすることで、運搬が容易にできるととともに、保管スペースの軽減に寄与できる。 It is desirable that the width of the water stop member 10 is determined by the specifications of the structure (opening) in which the water stop member 10 is installed, and the height of the water stop member 10 is determined according to the characteristics of flooding. For example, if the width of the door 12 is wide, a water blocking member 10 having a wide width is selected accordingly. Further, the height of the water blocking member 10 may be selected by adding a margin value to the height of the flooding that has occurred in the past. Further, various protrusions may be present on one side (indoor side) of the door 12. For example, as shown in FIGS. 10 and 11, there is a door 12 provided with a mailbox 32 on one side (indoor side). When the waterproof member 10 is applied to such a door 12, the height of the waterproof member 10 is selected so as not to interfere with (non-interfere with) the post box 32. FIG. 10 is a diagram showing an installation example of a water blocking member 10 having a standard size (height) (for example, a water blocking member 10 that can be used in an area where flooding up to about 50 cm is expected). FIG. 10 shows an example in which a water blocking member 10 having a second gap B thinner than the thickness of the post box 32 and a height lower than the lower end position of the post box 32 is installed. As described above, by making the water blocking member 10 the minimum necessary size, it is possible to easily carry the water stop member 10 and contribute to the reduction of the storage space.

図１１は、冠水高さが高いことが予想される地域で適用可能な止水部材１０の設置例である。このような地域で利用するする止水部材１０は、第二の隙間Ｂが郵便ポスト３２の厚みより厚く、高さが郵便ポスト３２の少なくとも一部を覆うような形状にすることができる。図１１の場合、止水部材１０が郵便ポスト３２をほぼ覆っている。このように、扉１２の突起物を覆うように止水部材１０を構成することにより、冠水高さが高い場合でも、止水が良好にできる。なお、いずれの場合も、扉１２が閉じられた状態で、第二の隙間Ｂに水を導くことができるので、冠水時に扉１２を容易に開けて屋外に移動することができる。また、救助等のために扉１２を容易に開けて屋内に入ることができる。なお、図１０、図１１に示す止水部材１０は、図４等で説明する止水部材１０と第二の隙間Ｂの厚み及び高さが異なるのみで、基本的な構成は同じであり、同様の効果を得ることができる。 FIG. 11 is an installation example of the water blocking member 10 that can be applied in an area where the flood height is expected to be high. The water blocking member 10 used in such an area can be shaped so that the second gap B is thicker than the thickness of the post box 32 and the height covers at least a part of the post box 32. In the case of FIG. 11, the water blocking member 10 substantially covers the post box 32. By configuring the water blocking member 10 so as to cover the protrusions of the door 12 in this way, the water can be stopped well even when the flood height is high. In either case, since water can be guided to the second gap B with the door 12 closed, the door 12 can be easily opened and moved outdoors when flooded. In addition, the door 12 can be easily opened to enter the room for rescue or the like. The water stop member 10 shown in FIGS. 10 and 11 has the same basic configuration except that the thickness and height of the second gap B are different from those of the water stop member 10 described with reference to FIGS. 4 and the like. A similar effect can be obtained.

このように、第１実施形態によれば、取り扱いやすく設置や撤去が容易な止水部材１０を提供できる。また、止水部材１０と扉１２との間に形成される第二の隙間Ｂに水を挿入するので、冠水時でも扉１２の表裏に作用する水圧差が低減可能となり、扉１２の開放を容易にできる。つまり、止水の前後においても取り扱いが容易な止水部材１０が提供できる。 As described above, according to the first embodiment, it is possible to provide the water blocking member 10 which is easy to handle and easy to install and remove. Further, since water is inserted into the second gap B formed between the water blocking member 10 and the door 12, the difference in water pressure acting on the front and back of the door 12 can be reduced even when flooded, and the door 12 can be opened. You can easily do it. That is, it is possible to provide the water stop member 10 which is easy to handle even before and after the water stop.

第２実施形態．
図１２に第２実施形態の止水部材４０の斜視図を示す。この止水部材４０も第１実施形態の止水部材１０と同様に、第一の部分４２と第二の部分４４を備える。図１２は、設置時に扉１２に面しない側（屋内側）の第一の部分４２及び第二の部分４４が見えている図である。図１２に示すように、第一の部分４２と第二の部分４４とは、実質的に同一平面上に位置する。つまり、止水部材４０の少なくとも他方側（屋外側）は、扁平な面を有する。第一の部分４２は、構造物の開口部（ドア枠１８）の一方と他方とを仕切る扉１２が閉じられた状態で、扉１２の下縁部１２ａまたは側縁部１２ｂと、扉１２に対して一方側に位置され他方を向いた構造物の支持面と、の間の第一の隙間Ａに挿入される。すなわち、第一の部分４２は、止水部材４０を構造物の開口部、すなわちドア枠１８に設置する場合に、支持面となる各戸当りと扉１２との間に形成される第一の隙間Ａに挿入される部分である（図３参照）。具体的には、第一の部分４２のうちドア枠１８の幅方向に沿って形成された下部挿入部４２ａは、扉１２が閉じられることにより、下部戸当り１８ａと下縁部１２ａとによって挟持される。同様に、第一の部分４２のうちドア枠１８の縦方向に沿って形成された縦挿入部４２ｂは、扉１２が閉じられることにより、縦戸当り１８ｂと側縁部１２ｂとによって挟持される。 Second embodiment.
FIG. 12 shows a perspective view of the water blocking member 40 of the second embodiment. The water stop member 40 also includes a first portion 42 and a second portion 44, similarly to the water stop member 10 of the first embodiment. FIG. 12 is a diagram in which the first portion 42 and the second portion 44 on the side not facing the door 12 (indoor side) are visible at the time of installation. As shown in FIG. 12, the first portion 42 and the second portion 44 are substantially coplanar. That is, at least the other side (outdoor side) of the water blocking member 40 has a flat surface. The first portion 42 is provided on the lower edge portion 12a or the side edge portion 12b of the door 12 and the door 12 in a state where the door 12 that separates one and the other of the opening (door frame 18) of the structure is closed. It is inserted into the first gap A between the support surface of the structure located on one side and facing the other. That is, the first portion 42 is a first gap formed between each door stop serving as a support surface and the door 12 when the water blocking member 40 is installed in the opening of the structure, that is, the door frame 18. This is the part inserted in A (see FIG. 3). Specifically, of the first portion 42, the lower insertion portion 42a formed along the width direction of the door frame 18 is sandwiched by the lower door stop 18a and the lower edge portion 12a when the door 12 is closed. Will be done. Similarly, of the first portion 42, the vertical insertion portion 42b formed along the vertical direction of the door frame 18 is sandwiched between the vertical door contact 18b and the side edge portion 12b when the door 12 is closed. ..

第二の部分４４は、第一の部分４２よりも扉１２の周縁部から離れて位置される。つまり、扉１２の周縁部である下縁部１２ａ及び側縁部１２ｂに挟持される第一の部分４２より第二の部分４４は内側に位置される。前述したように、第一の部分４２と第二の部分４４とは、実質的に同一平面上に位置するので、第一の部分４２が、第一の隙間Ａに挿入され、ドア枠１８と扉１２との間に挟持されている場合、第二の部分４４は扉１２の一方側（屋内側）の下部Ｃの部分で、実質的に扉１２に面する（接触する）。 The second portion 44 is located farther from the peripheral edge of the door 12 than the first portion 42. That is, the second portion 44 from the first portion 42 sandwiched between the lower edge portion 12a and the side edge portion 12b, which are the peripheral edges of the door 12, is located inside. As described above, since the first portion 42 and the second portion 44 are substantially on the same plane, the first portion 42 is inserted into the first gap A, and the door frame 18 and the first portion 42 are inserted into the first gap A. When sandwiched between the door 12 and the door 12, the second portion 44 is a portion of the lower portion C on one side (indoor side) of the door 12 and substantially faces (contacts) the door 12.

また、下部挿入部４２ａ及び縦挿入部４２ｂの一方側、すなわちドア枠１８に設置した場合に屋内側に向く側には、シール部材４６が固定されている。シール部材４６は、第１実施形態のシール部材２４と同じであり、同様の機能を有する。すなわち、シール部材４６は、例えば、柔軟性（可撓性、弾性）を有する材料、例えば合成樹脂材料（ゴム、エラストマ、柔軟性樹脂等）で形成されている。例えば、独立発泡型の気泡を多く含むゴム材料で、温度変化に対する劣化が少なく、耐摩耗性のある材料で構成することが望ましい。一例として、エプトシーラー（登録商標）等を利用することができる。 Further, the seal member 46 is fixed to one side of the lower insertion portion 42a and the vertical insertion portion 42b, that is, the side facing the indoor side when installed in the door frame 18. The seal member 46 is the same as the seal member 24 of the first embodiment, and has the same function. That is, the seal member 46 is made of, for example, a material having flexibility (flexibility, elasticity), for example, a synthetic resin material (rubber, elastomer, flexible resin, etc.). For example, it is desirable to use a rubber material containing a large amount of independent foam type bubbles, which is less deteriorated by temperature changes and has wear resistance. As an example, Eptsealer (registered trademark) and the like can be used.

また、止水部材４０は、第二の部分４４において、下部挿入部４２ａから離れた位置に止水部材４０を運搬するときやドア枠１８に設置する際に用いる取っ手４８が例えば左右２カ所に形成されている。止水部材４０は、第１実施形態の止水部材１０と異なり、手指を挿入し易い広い第二の隙間Ｂを持たないので、屋内側に突出して取っ手４８が有効である。取っ手４８を用いることで、容易に止水部材４０を運搬したり、ドア枠１８に設置する際に位置決めすることができる。なお、取っ手４８に代えて、または加えて例えば第二の部分４４の上端部（上面部）に別の取っ手を設けてもよい。また、止水部材４０にストラップ等を付けてもよく、同様の効果を得ることができる。 Further, in the second portion 44, the water stop member 40 has two handles 48 on the left and right, for example, when the water stop member 40 is transported to a position away from the lower insertion portion 42a or when the water stop member 40 is installed on the door frame 18. It is formed. Unlike the water stop member 10 of the first embodiment, the water stop member 40 does not have a wide second gap B into which a finger can be easily inserted, so that the handle 48 projects to the indoor side and is effective. By using the handle 48, the water blocking member 40 can be easily transported or positioned when it is installed on the door frame 18. In addition, instead of the handle 48, or in addition, another handle may be provided, for example, on the upper end portion (upper surface portion) of the second portion 44. Further, a strap or the like may be attached to the water blocking member 40, and the same effect can be obtained.

止水部材４０は、例えば、扁平な金属板（例えば、鉄板やステンレス板）や樹脂（例えば、繊維強化プラスチック等）を用いて形成することができる。 The water blocking member 40 can be formed by using, for example, a flat metal plate (for example, an iron plate or a stainless steel plate) or a resin (for example, a fiber reinforced plastic).

このように構成される止水部材４０の設置例を図１３を用いて説明する。図１３は、止水部材４０の設置状態を示す縦断面図である。止水部材４０も第１実施形態の止水部材１０と同様に、扉１２が開かれた状態（屋外側に外開きの状態）のときに、ドア枠１８の開口部に設置される。すなわち、扉１２が閉じられたときに当該扉１２の下縁部１２ａと下部戸当り１８ａとの間及び側縁部１２ｂと縦戸当り１８ｂとの間に形成される第一の隙間Ａに第一の部分４２が挿入されるように設置される。具体的には、止水部材４０の第一の部分４２のうち下部挿入部４２ａが下部戸当り１８ａに当接するように挿入され、縦挿入部４２ｂが縦戸当り１８ｂに当接するように挿入される（図３参照）。 An installation example of the water blocking member 40 configured in this way will be described with reference to FIG. FIG. 13 is a vertical sectional view showing an installed state of the water blocking member 40. Similar to the water stop member 10 of the first embodiment, the water stop member 40 is also installed in the opening of the door frame 18 when the door 12 is in the open state (outside open state to the outdoor side). That is, when the door 12 is closed, the first gap A formed between the lower edge portion 12a of the door 12 and the lower door stop 18a and between the side edge portion 12b and the vertical door stop 18b is the first. It is installed so that one part 42 is inserted. Specifically, of the first portion 42 of the water blocking member 40, the lower insertion portion 42a is inserted so as to abut against the lower door stop 18a, and the vertical insertion portion 42b is inserted so as to abut against the vertical door stop 18b. (See Fig. 3).

第一の隙間Ａに止水部材４０を挿入した後、図１３に示すように、扉１２を閉じる。扉１２を閉じることにより、下縁部１２ａが下部戸当り１８ａに対面し、側縁部１２ｂが縦戸当り１８ｂに対面する。第１実施形態で示したように、下部戸当り１８ａ、縦戸当り１８ｂ、上部戸当り１８ｃには、パッキン２８（シール部材）が配置され、扉１２が閉じられたときに、パッキン２８に接触する、またはパッキン２８が変形するようになっている。 After inserting the water blocking member 40 into the first gap A, the door 12 is closed as shown in FIG. By closing the door 12, the lower edge portion 12a faces the lower door contact 18a, and the side edge portion 12b faces the vertical door contact 18b. As shown in the first embodiment, packing 28 (seal member) is arranged at the lower door contact 18a, the vertical door contact 18b, and the upper door contact 18c, and comes into contact with the packing 28 when the door 12 is closed. Or the packing 28 is designed to be deformed.

第１実施形態と同様に、扉１２の下部Ｃにおける第一の隙間Ａは、止水部材４０の第一の部分４２が挿入されるとパッキン２８が更に変形して（潰れて）第一の隙間Ａにおける止水部材４０の第一の部分４２の挿入状態を許容する。そして、第１実施形態の止水部材１０と同様に、縦挿入部４２ｂに固定されたシール部材４６が縦戸当り１８ｂに固定されたパッキン２８に当接して、互いにまたは一方が弾性変形する。同様に、下部挿入部４２ａに固定されたシール部材４６が下部戸当り１８ａに固定されたパッキン２８に当接して、互いにまたは一方が弾性変形する。その結果、パッキン２８は、止水部材４０の第一の部分４２が介在しない場合に比べて大きく変形する。そして、ドア枠１８、第一の部分４２（止水部材４０）、扉１２の三者の密着性（水密性）が向上される。つまり、仮に扉１２の他方側（屋外側）で冠水した場合でも、シール部材４６及びパッキン２８により止水部材４０の一方側（屋内側）がシール（止水）されるので、止水部材４０の周囲から屋内側へ水が浸入することが抑制できる。 Similar to the first embodiment, in the first gap A in the lower portion C of the door 12, the packing 28 is further deformed (crushed) when the first portion 42 of the water blocking member 40 is inserted. The insertion state of the first portion 42 of the water blocking member 40 in the gap A is allowed. Then, similarly to the water blocking member 10 of the first embodiment, the seal member 46 fixed to the vertical insertion portion 42b abuts on the packing 28 fixed to the vertical door stop 18b, and one or the other is elastically deformed. Similarly, the seal member 46 fixed to the lower insertion portion 42a abuts on the packing 28 fixed to the lower door stop 18a, and one or the other is elastically deformed. As a result, the packing 28 is greatly deformed as compared with the case where the first portion 42 of the water blocking member 40 does not intervene. Then, the adhesion (watertightness) of the door frame 18, the first portion 42 (water blocking member 40), and the door 12 is improved. That is, even if the other side (outdoor side) of the door 12 is flooded, the seal member 46 and the packing 28 seal (water stop) one side (indoor side) of the water stop member 40, so that the water stop member 40 It is possible to prevent water from entering from the surrounding area to the indoor side.

なお、図１３の例では、シール部材４６及びパッキン２８を用いる場合を示したが、パッキン２８を省略してもよい。例えば、構造物の仕様によっては、ドア枠１８側のパッキン２８がない場合がある。このような場合は、ドア枠１８と第一の部分４２との間のシールをシール部材４６のみで行うようにしてもよい。この場合も、第一の隙間Ａに、第一の部分４２及びシール部材４６が介在する（挟み込まれる）ことにより、ドア枠１８、第一の部分４２（止水部材４０）、扉１２の三者の密着性（水密性）を向上させることができる。 In the example of FIG. 13, the case where the seal member 46 and the packing 28 are used is shown, but the packing 28 may be omitted. For example, depending on the specifications of the structure, the packing 28 on the door frame 18 side may not be provided. In such a case, the sealing between the door frame 18 and the first portion 42 may be performed only by the sealing member 46. Also in this case, the door frame 18, the first portion 42 (water blocking member 40), and the door 12 are formed by interposing (sandwiching) the first portion 42 and the sealing member 46 in the first gap A. It is possible to improve the adhesion (watertightness) of a person.

なお、図１２に示すように、シール部材４６は、第一の部分４２（下部挿入部４２ａ、縦挿入部４２ｂ）の一方側（屋内側）のみに設けられる。また、シール部材４６は、第一の部分４２の外縁部４２ｃから離れた位置に固定されている。つまり、下部挿入部４２ａに固定されるシール部材４６は、外縁部４２ｃより第二の部分４４に近い位置に固定されている。同様に、縦挿入部４２ｂに固定されるシール部材４６は、外縁部４２ｃより第二の部分４４に近い位置に固定されている。このように、シール部材４６を外縁部４２ｃから離れた位置に固定することにより、例えば止水部材４０の保管時に、シール部材４６が他の物体（例えば床や壁）と接触する可能性が低減できる。その結果、シール部材４６の保管時の劣化が軽減できる。例えばシール部材４６が保管時に壁や床に接触して長時間圧縮変形した状態が継続されて弾性力（復元力）が低下してしまうことが抑制できる。 As shown in FIG. 12, the seal member 46 is provided only on one side (indoor side) of the first portion 42 (lower insertion portion 42a, vertical insertion portion 42b). Further, the seal member 46 is fixed at a position away from the outer edge portion 42c of the first portion 42. That is, the seal member 46 fixed to the lower insertion portion 42a is fixed at a position closer to the second portion 44 than the outer edge portion 42c. Similarly, the seal member 46 fixed to the vertical insertion portion 42b is fixed at a position closer to the second portion 44 than the outer edge portion 42c. By fixing the seal member 46 at a position away from the outer edge portion 42c in this way, the possibility that the seal member 46 comes into contact with another object (for example, a floor or a wall) can be reduced, for example, when the water stop member 40 is stored. .. As a result, deterioration of the seal member 46 during storage can be reduced. For example, it is possible to prevent the sealing member 46 from coming into contact with the wall or floor during storage and being continuously compressed and deformed for a long time to reduce the elastic force (restoring force).

ところで、扉１２が閉じられた状態で、扉１２の他方側（屋外側）が冠水した場合、扉１２の屋外側に水圧が作用して扉１２が容易に開けない場合があるという問題がある。例えば、屋外の冠水が初期の段階では、構造物内（屋内）に避難している場合が多い。一方、冠水が所定値を越えた場合には、より安全な避難場所に移動することが望ましい場合がある。そこで、第２実施形態の止水部材４０は、扉１２が閉じた状態で、かつ止水部材４０がドア枠１８に設置された状態で、扉１２の他方側（屋外側）から水（冠水した水）を止水部材４０と扉１２との間に導入できるように構成されている。 By the way, when the other side (outdoor side) of the door 12 is flooded with the door 12 closed, there is a problem that the door 12 may not be easily opened due to water pressure acting on the outdoor side of the door 12. .. For example, in the early stages of outdoor flooding, there are many cases of evacuation inside the structure (indoors). On the other hand, if the flooding exceeds a predetermined value, it may be desirable to move to a safer evacuation site. Therefore, in the water stop member 40 of the second embodiment, with the door 12 closed and the water stop member 40 installed on the door frame 18, water (submerged) from the other side (outdoor side) of the door 12. Water) can be introduced between the water blocking member 40 and the door 12.

前述したように、扉１２は、ドア枠１８に対して開閉自在とするために、一般的にドア枠１８と扉１２の下面部１２ｄ、側面部１２ｅ、上面部１２ｆとの間には隙間が形成されている。例えば、第１実施形態の図５を参照すると、側面部１２ｅとドア枠１８との間には、縦隙間Ｄが形成されている。また、図６を参照すると、下面部１２ｄとドア枠１８との間には、下部隙間Ｅが形成されている。そのため、冠水した水の一部は、ドア枠１８と扉１２との間を通過することができる。図５、図６に示すように、扉１２の下縁部１２ａと下部挿入部１４ａとが当接し、側縁部１２ｂと縦挿入部１４ｂとが当接するが、扉１２の表面は完全な平面ではなく、凹凸が存在する場合がある。例えば、意匠性の向上のために例えば縦縞等のような凹凸の模様が付与されている場合がある。止水部材４０の場合、下縁部１２ａと下部挿入部４２ａとの間や側縁部１２ｂと縦挿入部４２ｂとの間にはシール部材を介在させない。そのため、図１３に示すように下部隙間Ｅ（及び縦隙間Ｄ）から浸入した水は、下縁部１２ａと下部挿入部４２ａとの間（及び側縁部１２ｂと縦挿入部４２ｂとの間）を通り、矢印Ｑで示すように、止水部材４０の第二の部分４４と扉１２の一方側の面（屋内側の面）との間に意図的に浸入させられる。 As described above, in order to allow the door 12 to be opened and closed with respect to the door frame 18, generally, there is a gap between the door frame 18 and the lower surface portion 12d, the side surface portion 12e, and the upper surface portion 12f of the door 12. It is formed. For example, referring to FIG. 5 of the first embodiment, a vertical gap D is formed between the side surface portion 12e and the door frame 18. Further, referring to FIG. 6, a lower gap E is formed between the lower surface portion 12d and the door frame 18. Therefore, a part of the flooded water can pass between the door frame 18 and the door 12. As shown in FIGS. 5 and 6, the lower edge portion 12a of the door 12 and the lower insertion portion 14a are in contact with each other, and the side edge portion 12b and the vertical insertion portion 14b are in contact with each other, but the surface of the door 12 is completely flat. Instead, there may be irregularities. For example, in order to improve the design, an uneven pattern such as vertical stripes may be added. In the case of the water stop member 40, no sealing member is interposed between the lower edge portion 12a and the lower insertion portion 42a or between the side edge portion 12b and the vertical insertion portion 42b. Therefore, as shown in FIG. 13, the water that has entered from the lower gap E (and the vertical gap D) is between the lower edge portion 12a and the lower insertion portion 42a (and between the side edge portion 12b and the vertical insertion portion 42b). As shown by the arrow Q, it is intentionally inserted between the second portion 44 of the water blocking member 40 and one side surface (indoor side surface) of the door 12.

この場合、下部隙間Ｅ（及び縦隙間Ｄ）を通過して浸入する水の流れは、扉１２の他方側（屋外側）の水頭高さと扉１２の一方側（屋内側）の第二の隙間Ｂにおける水頭高さとが同じになった時点で停止する。止水部材４０の場合、第二の部分４４の他方側（屋外側）と扉１２の一方側（屋内側）とは接近しているための、両者間に形成される隙間は小さいが、屋外側の水圧により水が下部隙間Ｅ（縦隙間Ｄ）を介して押し込まれる。この場合、扉１２の他方側（屋外側）の水圧Ｐ１と扉１２の一方側（屋内側）と第二の部分４４の他方側（屋外側）との間の隙間における水圧Ｐ２とがつり合う（打ち消し合う）。その結果、扉１２は、水中に浸かっている場合と同じ状態になり、扉１２に作用する力は水の抵抗のみになり容易に扉１２を開くことができる。その結果、構造物の屋内側にいた利用者は、扉１２を開き屋外に移動することが可能になる。なお、この場合もドア枠１８と止水部材４０の第一の部分４２との水密状態は、シール部材４６やパッキン２８により維持されるので、水が屋内側に浸入してしまうことが抑制できる。また、扉１２が開かれた場合、それまでドア枠１８に対して第一の部分４２を押圧していた力が解放されるが、第一の部分４２及び第二の部分４４の他方側（屋外側）は、水圧が作用してドア枠１８側（下部戸当り１８ａ側、縦戸当り１８ｂ側）に押圧されるので、第一の部分４２の付勢状態が維持される。その結果、扉１２を開いた場合でも止水部材４０をドア枠１８に対して自立させやすくなり、水圧により倒れたり、止水可能な姿勢が損なわれないようにすることができる。 In this case, the flow of water that enters through the lower gap E (and the vertical gap D) is the head height on the other side (outdoor side) of the door 12 and the second gap on one side (indoor side) of the door 12. It stops when the height of the head in B becomes the same. In the case of the water stop member 40, since the other side (outdoor side) of the second portion 44 and one side (indoor side) of the door 12 are close to each other, the gap formed between the two is small, but the shop Water is pushed in through the lower gap E (vertical gap D) by the water pressure on the outside. In this case, the water pressure P1 on the other side (outdoor side) of the door 12 and the water pressure P2 in the gap between one side (indoor side) of the door 12 and the other side (outdoor side) of the second portion 44 are balanced ( Cancel each other). As a result, the door 12 is in the same state as when it is immersed in water, and the force acting on the door 12 is only the resistance of water, and the door 12 can be easily opened. As a result, the user who was on the indoor side of the structure can open the door 12 and move to the outside. In this case as well, the watertight state between the door frame 18 and the first portion 42 of the water blocking member 40 is maintained by the sealing member 46 and the packing 28, so that it is possible to prevent water from entering the indoor side. .. Further, when the door 12 is opened, the force that has previously pressed the first portion 42 against the door frame 18 is released, but the other side of the first portion 42 and the second portion 44 ( The outdoor side) is pressed against the door frame 18 side (18a side per lower door and 18b side per vertical door) by the action of water pressure, so that the urging state of the first portion 42 is maintained. As a result, even when the door 12 is opened, the water blocking member 40 can be easily made to stand on the door frame 18 so as not to fall down due to water pressure or to impair the posture in which the water can be stopped.

図１４は、止水部材４０を用いた止水構造の変形例を示す横断面図である。具体的には、第二の部分４４と扉１２の一方側（屋内側）との間の隙間を拡大するためのスペーサ５０を介在させた場合を示す例である。前述したように、止水部材４０は、第一の部分４２と第二の部分４４が、実質的に同一平面上に位置するため、第二の部分４４と扉１２との隙間は僅かである。つまり、止水部材４０と扉１２との間に導入できる水の量が少量である。そこで、止水部材４０と扉１２との間にスペーサ５０を介在させる。スペーサ５０は、例えば、ブロック形状の樹脂（プラスチック、ゴム等）や木材等で構成することができる。スペーサ５０は、例えば、止水部材４０と扉１２との間で、縦挿入部４２ｂに沿った位置に連続的または間欠的に配置することができる。スペーサ５０は、止水部材４０側に固定してもよいし、扉１２側に固定してもよい。また、止水部材４０を設置するときに、単体のスペーサ５０を配置するようにしてもよい。図１４に示すように、止水部材４０と扉１２との間にスペーサ５０を介在させることにより隙間Ｆが形成され、下部隙間Ｅ（図１３参照）や縦隙間Ｄを通過した水をより多く、また確実に扉１２と止水部材４０の間に導入することができる。つまり、扉１２の一方側（屋内側）に十分な水を導入し、冠水時に扉１２が水の中に浸かっている状態をより確実に実現して、扉１２をより容易に開けるようにすることができる。なお、スペーサ５０の厚みは、数ｍｍ～数ｃｍ程度とすることができる。 FIG. 14 is a cross-sectional view showing a modified example of the water blocking structure using the water blocking member 40. Specifically, it is an example showing the case where the spacer 50 for expanding the gap between the second portion 44 and one side (indoor side) of the door 12 is interposed. As described above, in the water blocking member 40, since the first portion 42 and the second portion 44 are located substantially on the same plane, the gap between the second portion 44 and the door 12 is small. .. That is, the amount of water that can be introduced between the water blocking member 40 and the door 12 is small. Therefore, a spacer 50 is interposed between the water blocking member 40 and the door 12. The spacer 50 can be made of, for example, a block-shaped resin (plastic, rubber, etc.), wood, or the like. The spacer 50 can be continuously or intermittently arranged, for example, between the water blocking member 40 and the door 12 at a position along the vertical insertion portion 42b. The spacer 50 may be fixed to the water blocking member 40 side or the door 12 side. Further, when installing the water blocking member 40, a single spacer 50 may be arranged. As shown in FIG. 14, a gap F is formed by interposing a spacer 50 between the water blocking member 40 and the door 12, and more water has passed through the lower gap E (see FIG. 13) and the vertical gap D. Also, it can be reliably introduced between the door 12 and the water blocking member 40. That is, sufficient water is introduced into one side (indoor side) of the door 12 so that the state in which the door 12 is submerged in water at the time of flooding is more reliably realized, and the door 12 can be opened more easily. be able to. The thickness of the spacer 50 can be about several mm to several cm.

このように、第一の部分４２と第二の部分４４とが実質的に同一平面上に位置するようにした止水部材４０は、シンプルな構成で取り扱いやすく設置や撤去が容易となる。また、止水部材４０と扉１２との間に水を挿入するので、冠水時でも扉１２の表裏に作用する水圧差が低減可能となり、扉１２の開放を容易にできる。つまり、止水の前後においても取り扱いが容易な止水部材４０が提供できる。 As described above, the water blocking member 40 in which the first portion 42 and the second portion 44 are substantially located on the same plane has a simple structure and is easy to handle and install or remove. Further, since water is inserted between the water blocking member 40 and the door 12, the difference in water pressure acting on the front and back of the door 12 can be reduced even when flooded, and the door 12 can be easily opened. That is, it is possible to provide the water stop member 40 that is easy to handle even before and after the water stop.

第３実施形態．
図１５は、第３実施形態の止水部材６０の横断面図である。止水部材６０は、第１実施形態で示した止水部材１０の変形例である。止水部材１０の場合、第一の部分１４や第二の部分１６は、水圧に耐えうる剛性を確保するために、例えば金属で構成される。その場合、重量が重くなってしまい、運搬性が低下してしまう場合がある。一方、止水部材１０を樹脂で構成する場合、軽量化は容易であるが剛性の確保が難しくなる場合がある。そこで、止水部材６０は、軽量化を重視して表面部分を樹脂で構成するとともに、補強を施し水圧に耐えうる構造を有する。 Third embodiment.
FIG. 15 is a cross-sectional view of the water blocking member 60 of the third embodiment. The water stop member 60 is a modified example of the water stop member 10 shown in the first embodiment. In the case of the water blocking member 10, the first portion 14 and the second portion 16 are made of, for example, metal in order to secure rigidity that can withstand water pressure. In that case, the weight becomes heavy and the transportability may decrease. On the other hand, when the water blocking member 10 is made of resin, it is easy to reduce the weight, but it may be difficult to secure the rigidity. Therefore, the water blocking member 60 has a structure in which the surface portion thereof is made of resin with an emphasis on weight reduction and is reinforced to withstand water pressure.

止水部材６０は、第一の部分６２と第二の部分６４を備える。そして、第二の部分６４は軽量化のため樹脂の薄板材で形成されている。一方、第一の部分６２（下部挿入部６２ａ、縦挿入部６２ｂ）は第二の部分６４に水圧がかかったときに挟持されていない部分が撓んだりしないように、例えば金属で形成されて、例えば矩形のフレーム６６にネジ等の締結部材により固定されている。第二の部分６４は、フレーム６６の他面側（屋外側）に固定されている。フレーム６６は例えば金属で構成することができるが、止水部材６０の全てを金属で形成する場合に比べて軽量化に寄与できる。また、フレーム６６を合成の高い樹脂で形成してもよい。フレーム６６の一方側（屋内側）には、樹脂の薄板材等で形成される化粧板６８ａが固定されている。なお、図１５の場合、第二の部分６４の外縁部をフレーム６６に固定するための化粧板６８ｂを配置しているが、第二の部分６４を樹脂成形するときに化粧板６８ｂを一体的に成形してもよい。また、フレーム６６の底面部には、樹脂の薄板材等で形成される底面板６８ｃが固定されている。なお、図示を省略しているが、フレーム６６の上面部には、樹脂の薄板材等で形成される上面板が固定されている。つまり、フレーム６６は樹脂の薄板材で覆われている。また、第二の部分６４と化粧板６８ａとの間には、複数の補強部材７０が配置されている。補強部材７０は、例えば高さ方向（紙面鉛直方向）に延びる、例えば弾性変形し難い樹脂ブロック等で構成され、第二の部分６４を一方側（屋内側）から支える。 The water blocking member 60 includes a first portion 62 and a second portion 64. The second portion 64 is made of a thin resin plate for weight reduction. On the other hand, the first portion 62 (lower insertion portion 62a, vertical insertion portion 62b) is formed of, for example, metal so that the portion that is not sandwiched does not bend when water pressure is applied to the second portion 64. For example, it is fixed to a rectangular frame 66 by a fastening member such as a screw. The second portion 64 is fixed to the other surface side (outdoor side) of the frame 66. Although the frame 66 can be made of metal, for example, it can contribute to weight reduction as compared with the case where all of the water blocking members 60 are made of metal. Further, the frame 66 may be formed of a highly synthetic resin. A decorative plate 68a made of a thin resin plate or the like is fixed to one side (indoor side) of the frame 66. In the case of FIG. 15, the decorative plate 68b for fixing the outer edge portion of the second portion 64 to the frame 66 is arranged, but the decorative plate 68b is integrally formed when the second portion 64 is resin-molded. May be molded into. Further, a bottom plate 68c formed of a thin resin plate or the like is fixed to the bottom surface of the frame 66. Although not shown, a top plate made of a thin resin plate or the like is fixed to the top surface of the frame 66. That is, the frame 66 is covered with a thin resin plate material. Further, a plurality of reinforcing members 70 are arranged between the second portion 64 and the decorative plate 68a. The reinforcing member 70 is composed of, for example, a resin block that extends in the height direction (vertical direction of the paper surface) and is not easily elastically deformed, and supports the second portion 64 from one side (indoor side).

このように構成される止水部材６０は、樹脂の薄板材が多用されるので、軽量化に寄与できる。また、第二の部分６４は、フレーム６６や補強部材７０によって一方側（屋内側）から支えられるので、薄板材の第二の部分６４が水圧によって変形する（撓む）ことを抑制できる。 Since the water blocking member 60 configured in this way often uses a thin resin plate material, it can contribute to weight reduction. Further, since the second portion 64 is supported from one side (indoor side) by the frame 66 and the reinforcing member 70, it is possible to prevent the second portion 64 of the thin plate material from being deformed (bent) by water pressure.

図１６は、扉１２とドア枠１８との間に設置された状態の止水部材１０に水圧が付与された場合（第二の隙間Ｂに水が導入された場合）に、第二の部分１６の撓み（変形）による外れや水漏れを抑制するための止水構造を示す斜視図である。例えば、住宅の玄関の場合、扉１２の内側には玄関床面７２ａ（靴脱ぎ場）が広がり、さらに玄関床面７２ａから一段高くなったフロア床面７２ｂ（室内床面）があることがある。そこで、図１６に示す止水構造の場合、止水部材１０を（一方側）屋内側から支える支持部材７４を玄関床面７２ａとフロア床面７２ｂとの段差部分で固定する（突っ張る）ようにしている。支持部材７４は、例えば、支持バー７４ａ、突っ張り部７４ｂ、固定座部７４ｃ、高さ調整部７４ｄを含む。支持バー７４ａは、止水部材１０の幅方向に延びる棒状部材であり、止水部材１０に対して支持部材７４を設置する場合、第二の部分１６を他方側（屋外側）に押し戻さないように配置される。つまり、止水部材１０が、水圧により変形していない場合には、僅かな隙間を有して配置されるか、触れている姿勢（実質的に押圧しない姿勢）で配置される。したがって、第一の部分１４が下部戸当り１８ａ側から離れない（水密を低下させない）ようにしている。突っ張り部７４ｂは、支持バー７４ａと固定座部７４ｃとを接続して、仮に止水部材１０が一方側（屋内側）に、変形して支持バー７４ａを屋内側に押した場合に突っ張る。固定座部７４ｃは、玄関床面７２ａとフロア床面７２ｂとの段差部分に当接して、支持部材７４が屋内側に後退しないように支持する。高さ調整部７４ｄは、突っ張り部７４ｂの傾斜姿勢を調整して、玄関床面７２ａに位置する固定座部７４ｃに対する支持バー７４ａの高さを決定する。なお、支持部材７４は、玄関床面７２ａとフロア床面７２ｂとの段差部分以外、例えば屋内側の側壁７６と接触して突っ張るようにしてもよい。この場合、例えば支持バー７４ａに対する突っ張り部７４ｂの角度を調整可能として側壁７６に向かって延びるようにしてもよく、同様の効果を得ることができる。 FIG. 16 shows a second portion when water pressure is applied to the water blocking member 10 installed between the door 12 and the door frame 18 (when water is introduced into the second gap B). 16 is a perspective view showing a water blocking structure for suppressing disengagement and water leakage due to bending (deformation) of 16. For example, in the case of the entrance of a house, the entrance floor surface 72a (shoe removal area) may spread inside the door 12, and there may be a floor floor surface 72b (indoor floor surface) that is one step higher than the entrance floor surface 72a. .. Therefore, in the case of the waterproof structure shown in FIG. 16, the support member 74 that supports the waterproof member 10 from the (one side) indoor side is fixed (stretched) at the step portion between the entrance floor surface 72a and the floor floor surface 72b. ing. The support member 74 includes, for example, a support bar 74a, a tension portion 74b, a fixed seat portion 74c, and a height adjusting portion 74d. The support bar 74a is a rod-shaped member extending in the width direction of the water stop member 10, and when the support member 74 is installed with respect to the water stop member 10, the second portion 16 is not pushed back to the other side (outdoor side). Placed in. That is, when the water blocking member 10 is not deformed by water pressure, it is arranged with a slight gap or in a touching posture (a posture in which it is not substantially pressed). Therefore, the first portion 14 is prevented from being separated from the lower door contact 18a side (does not reduce the watertightness). The tension portion 74b connects the support bar 74a and the fixed seat portion 74c, and is tensioned when the water blocking member 10 is deformed to one side (indoor side) and the support bar 74a is pushed to the indoor side. The fixed seat portion 74c abuts on the stepped portion between the entrance floor surface 72a and the floor floor surface 72b, and supports the support member 74 so as not to retreat to the indoor side. The height adjusting portion 74d adjusts the inclined posture of the tension portion 74b to determine the height of the support bar 74a with respect to the fixed seat portion 74c located on the entrance floor surface 72a. The support member 74 may be stretched in contact with, for example, the side wall 76 on the indoor side, other than the stepped portion between the entrance floor surface 72a and the floor floor surface 72b. In this case, for example, the angle of the tension portion 74b with respect to the support bar 74a may be adjustable so as to extend toward the side wall 76, and the same effect can be obtained.

このように、止水部材１０に対して支持部材７４を用いることにより、止水部材１０の変形や設置ズレ、それらに伴う水漏れを抑制することができる。なお、支持部材７４は、止水部材１０の非変形時には、止水部材１０を押圧しないので、設置および取り外しが容易である。また、支持部材７４は組み立て式としてもよく、収納時には分解して収納スペースを低減することができる。また、支持部材７４は、止水部材４０にも適用可能であり同様な効果を得ることができる。 By using the support member 74 with respect to the water stop member 10 in this way, it is possible to suppress deformation of the water stop member 10, installation misalignment, and water leakage associated therewith. Since the support member 74 does not press the water stop member 10 when the water stop member 10 is not deformed, it is easy to install and remove. Further, the support member 74 may be an assembly type, and can be disassembled at the time of storage to reduce the storage space. Further, the support member 74 can be applied to the water blocking member 40, and the same effect can be obtained.

図１７は、止水部材１０の補強を行う場合の一例を示す斜視図である。図１７の場合、止水部材１０の第二の部分１６に補強部７８を形成して止水部材１０自体の剛性を増加させている。図１７の場合、補強部７８は、例えば、第二の部分１６の成形時にプレス加工等により、第二の部分１６の一部を一方側（屋内側）に突出させ、第二の部分１６の幅方向に延びる凸部が形成されている。このような補強部７８を形成することで、止水部材１０（第二の部分１６）が水圧により一方側（屋内側）に撓み（曲がり）、第一の部分１４がドア枠１８と扉１２とによる挟持部分から抜けてしまうことが抑制できる。補強部７８は、第２実施形態の止水部材４０にも適用可能であり、同様の効果を得ることができる。補強部７８は、図１７に示すような屋内側に突出した凸部の他、例えば、第二の隙間Ｂ側に突出した形状（屋内側から見ると凹部）にしてもよいし、波型形状にしてもよく、同様の効果を得ることができる。第２実施形態の止水部材４０に屋内側から見て凹部の補強部７８や波形の補強部７８を適用することにより、スペーサ５０を介在させた場合と同じ状態となり、水を導入するための隙間Ｆを形成することができる。また、補強部７８は、棒状の別部材（リブ）を溶接や接着等により固定してもよく、同様の効果を得ることができる。 FIG. 17 is a perspective view showing an example of a case where the water blocking member 10 is reinforced. In the case of FIG. 17, a reinforcing portion 78 is formed in the second portion 16 of the waterproof member 10 to increase the rigidity of the waterproof member 10 itself. In the case of FIG. 17, the reinforcing portion 78 projects a part of the second portion 16 to one side (indoor side) by press working or the like at the time of forming the second portion 16, for example, and the second portion 16 is formed. A convex portion extending in the width direction is formed. By forming such a reinforcing portion 78, the water blocking member 10 (second portion 16) bends (bends) to one side (indoor side) due to water pressure, and the first portion 14 forms the door frame 18 and the door 12. It is possible to prevent the door from coming off from the pinched portion. The reinforcing portion 78 can also be applied to the water blocking member 40 of the second embodiment, and the same effect can be obtained. In addition to the convex portion protruding toward the indoor side as shown in FIG. 17, the reinforcing portion 78 may have a shape protruding toward the second gap B side (concave portion when viewed from the indoor side), or may have a corrugated shape. However, the same effect can be obtained. By applying the concave reinforcing portion 78 and the corrugated reinforcing portion 78 to the water blocking member 40 of the second embodiment when viewed from the indoor side, the state is the same as when the spacer 50 is interposed, and water is introduced. A gap F can be formed. Further, the reinforcing portion 78 may have another rod-shaped member (rib) fixed by welding, adhesion, or the like, and the same effect can be obtained.

ところで、上述した第１実施形態の止水部材１０の場合、図７に示すように、底壁部２２ａを備えている。この場合、下部挿入部１４ａが下部戸当り１８ａと下縁部１２ａとの間に挟持されるので、止水性能が高い。一方、簡略化した別の実施例によれば、底壁部２２ａおよび下部挿入部１４ａを省略することができる。つまり、簡略化された止水部材１０の場合、縦挿入部１４ｂ、側壁部２２ｂ、第二の部分１６、側壁部２２ｂ、縦挿入部１４ｂが連続する形状としてもよい。この場合、止水部材１０を金属板で成形する場合、折り曲げ加工のみで成形可能となり、製造工数の削減および製造コストの低減に寄与することができる。なお、この場合、止水部材１０の底辺部のシールが低下する場合がある。この場合、底面部に沿って例えば、シール部材２４と同等のシール部材を設ける。このような簡易型の止水部材１０を設置する場合、止水部材１０は、縦戸当り１８ｂと側縁部１２ｂとの間に挟持される縦挿入部１４ｂのみで支持される。そして、第二の隙間Ｂのシールは、縦挿入部１４ｂと底辺部に固定されたシール部材とで行う。したがって、簡易型の止水部材１０を設置する場合は、止水部材１０を下方に押し下げて底辺部のシール部材を圧縮変形させた上で、扉１２を閉めて底辺部の水密性を維持するようにする。逆に下部挿入部１４ａのみで止水部材１０を挟持して縦挿入部１４ｂを省略するようにしてもよい。この場合、側壁部２２ｂの端部が縦戸当り１８ｂの端部に当接することになる。したがって、側壁部２２ｂにシール部材を固定しておくことにより、第二の隙間Ｂに対するシールを行い、第１実施形態の止水部材１０と同様に機能させることができる。 By the way, in the case of the water blocking member 10 of the first embodiment described above, as shown in FIG. 7, the bottom wall portion 22a is provided. In this case, since the lower insertion portion 14a is sandwiched between the lower door contact 18a and the lower edge portion 12a, the water blocking performance is high. On the other hand, according to another simplified embodiment, the bottom wall portion 22a and the lower insertion portion 14a can be omitted. That is, in the case of the simplified water stop member 10, the vertical insertion portion 14b, the side wall portion 22b, the second portion 16, the side wall portion 22b, and the vertical insertion portion 14b may be continuous. In this case, when the water blocking member 10 is molded from a metal plate, it can be molded only by bending, which can contribute to a reduction in manufacturing man-hours and a reduction in manufacturing cost. In this case, the seal at the bottom of the water blocking member 10 may be lowered. In this case, for example, a seal member equivalent to the seal member 24 is provided along the bottom surface portion. When such a simple type water blocking member 10 is installed, the water blocking member 10 is supported only by the vertical insertion portion 14b sandwiched between the vertical door contact 18b and the side edge portion 12b. Then, the seal of the second gap B is performed by the vertical insertion portion 14b and the seal member fixed to the bottom portion. Therefore, when installing the simple water stop member 10, the water stop member 10 is pushed downward to compress and deform the seal member at the bottom, and then the door 12 is closed to maintain the watertightness of the bottom. To do so. On the contrary, the water stop member 10 may be sandwiched only by the lower insertion portion 14a, and the vertical insertion portion 14b may be omitted. In this case, the end portion of the side wall portion 22b comes into contact with the end portion of the vertical door contact 18b. Therefore, by fixing the seal member to the side wall portion 22b, the second gap B can be sealed and can function in the same manner as the water stop member 10 of the first embodiment.

なお、図１０、図１１においては、扉１２の突起物の一例として、郵便ポスト３２を示したが、突起物は、これに限定されず、例えば、ドアノブや扉１２の下部に取り付けられたドアストッパ等でもよく、止水部材１０は、これらの突起物と非干渉であればよく、同様の効果を得ることができる。また、図１０は、止水部材１０の高さを突起物である郵便ポスト３２に干渉しないようにする場合を示し、図１１は、止水部材１０は、郵便ポスト３２を覆う場合を説明したが、これに限らず、止水部材１０と突起物とが非干渉となればよい。例えば、図１０、図１１では、第二の部分１６が扁平である場合を示したが、突起物の位置及び大きさに対応して、第二の部分１６の一部に突起物を受け入れるような形状にしてもよい。例えば、第二の部分１６の一部に凹部（屋内側に凹んだ部分）を設けたり、第二の部分１６の上部の一部を下方に向けて切り欠いた部分（下方に凹んだ部分）を設けて干渉しないようにしてもよい。 In FIGS. 10 and 11, the post box 32 is shown as an example of the protrusion of the door 12, but the protrusion is not limited to this, and the protrusion is not limited to this, for example, a door knob or a door attached to the lower part of the door 12. A stopper or the like may be used, and the water blocking member 10 may be non-interfering with these protrusions, and the same effect can be obtained. Further, FIG. 10 shows a case where the height of the water blocking member 10 does not interfere with the post box 32 which is a protrusion, and FIG. 11 illustrates a case where the water blocking member 10 covers the post box 32. However, the present invention is not limited to this, and it is sufficient that the water blocking member 10 and the protrusion do not interfere with each other. For example, in FIGS. 10 and 11, the case where the second portion 16 is flat is shown, but the protrusion is accepted in a part of the second portion 16 according to the position and size of the protrusion. It may have a different shape. For example, a recess (a recessed portion on the indoor side) may be provided in a part of the second portion 16, or a portion of the upper portion of the second portion 16 may be cut out downward (a recessed portion downward). May be provided to prevent interference.

上述した本発明の実施形態、変形例に係る止水部材または止水構造は、上述した実施形態、変形例に限定されず、特許請求の範囲に記載された範囲で種々の変更が可能である。本実施形態に係る止水部材または止水構造は、以上で説明した各実施形態の構成要素を適宜組み合わせることで構成してもよい。

止水部材は、構造物の開口部の一方と他方とを仕切る扉が閉じられた状態で、上記扉の下縁部または側縁部と、上記扉に対して上記一方に位置され上記他方を向いた上記構造物の支持面と、の間の第一の隙間に挿入される第一の部分と、上記第一の部分よりも上記扉の周縁部から離れて位置され、上記扉の下部の上記一方で、上記第一の隙間よりも大きい第二の隙間をあけて面した第二の部分と、を備える。この構成によれば、例えば、扉が閉じられた状態で第二の部分が扉の一方から第二の隙間をあけて面するので、扉と第二の部分との間に手指が挿入可能となる。その結果、設置作業の最後まで止水部材の支持が容易になり、止水部材の設置姿勢の調整が容易にできる。また、支持面と接する第一の部分より第二の部分が開口部の一方（例えば屋内側）に位置するので、止水部材の重心位置が開口部の一方側になる（偏る）。その結果、設置作業及び取り外し作業を行う場合に、止水部材が支持面に寄りかかり倒れにくい状態になるので、止水部材の取り扱いが容易になるとともに設置機能性が改善できる。
また、止水部材の上記第一の部分は、例えば、上記扉の上記他方の側から上記第二の隙間に水を導入可能に構成されてもよい。この構成によれば、例えば、扉の他方（例えば屋外側）が冠水して扉の他方に水圧がかかっている場合でも、扉の一方（例えば屋内側）と第二の部分で形成される第二の隙間に水が導入されるので、扉の一方と他方で水圧差が軽減される。その結果、取り扱いを容易にしつつ、扉の外が冠水した状態でも扉を開けやすくなり、設置時（止水時）の機能性(利便性)が改善（向上）できる。
また、止水部材の上記第一の部分には、例えば、上記第二の部分と上記扉の一方との間の上記第二の隙間に水を導入する連通溝が形成されていてもよい。この構成によれば、例えば、第二の隙間に積極的に水が導入できるので、扉の一方と他方とで水圧差をより効率的に軽減することができる。
また、止水部材の上記第二の部分は、例えば、上記扉の幅方向で上記構造物に接する位置まで延設されていてもよい。この構成によれば、例えば、扉の一方と他方とで水の受圧面積の差を小さくすることができる。その結果、冠水時の扉の開放に必要な力を低減することができる。
また、止水部材の上記第一の部分と上記支持面との間には、例えば、シール部材が介在してもよい。この構成によれば、第二の隙間に水が導入された場合でも第二の部材より構造物の一方側への水の浸入抑制効果がより向上できる。
また、止水部材の上記シール部材は、例えば、上記第一の部分の外縁部から離れた位置に固定されてもよい。この構成によれば、例えば、止水部材の保管時に、シール部材が他の物体（例えば床や壁）と接触する可能性が低減できる。その結果、シール部材の保管時の劣化（例えば弾性力の低下）が軽減できる。 The water-stopping member or the water-stopping structure according to the above-described embodiment and modification of the present invention is not limited to the above-mentioned embodiment and modification, and various modifications can be made within the scope of the claims. .. The water-stopping member or the water-stopping structure according to the present embodiment may be configured by appropriately combining the components of each of the above-described embodiments.
In addition, the appendix of the embodiment is disclosed below.
The water blocking member is located at the lower edge or side edge of the door and the other with respect to the door in a state where the door separating one and the other of the opening of the structure is closed. The first portion inserted into the first gap between the support surface of the structure facing and the first portion, located away from the peripheral edge of the door than the first portion, at the bottom of the door. On the other hand, it includes a second portion facing with a second gap larger than the first gap. According to this configuration, for example, when the door is closed, the second part faces with a second gap from one side of the door, so that a finger can be inserted between the door and the second part. Become. As a result, the water blocking member can be easily supported until the end of the installation work, and the installation posture of the water blocking member can be easily adjusted. Further, since the second portion from the first portion in contact with the support surface is located on one side of the opening (for example, the indoor side), the center of gravity of the water blocking member is located on one side of the opening (biased). As a result, when the installation work and the removal work are performed, the water stop member leans against the support surface and is less likely to fall down, so that the water stop member can be easily handled and the installation functionality can be improved.
Further, the first portion of the water blocking member may be configured so that water can be introduced into the second gap from the other side of the door, for example. According to this configuration, for example, even if the other side of the door (for example, the outdoor side) is flooded and the other side of the door is under water pressure, the first part of the door (for example, the indoor side) and the second part are formed. Since water is introduced into the gap between the two, the difference in water pressure between one door and the other is reduced. As a result, while facilitating handling, it becomes easier to open the door even when the outside of the door is flooded, and the functionality (convenience) at the time of installation (when the water is stopped) can be improved (improved).
Further, in the first portion of the water blocking member, for example, a communication groove for introducing water may be formed in the second gap between the second portion and one of the doors. According to this configuration, for example, since water can be positively introduced into the second gap, the water pressure difference between one of the doors and the other can be reduced more efficiently.
Further, the second portion of the water blocking member may be extended to a position in contact with the structure in the width direction of the door, for example. According to this configuration, for example, the difference in the water pressure receiving area between one of the doors and the other can be reduced. As a result, the force required to open the door when flooded can be reduced.
Further, for example, a seal member may be interposed between the first portion of the water blocking member and the support surface. According to this configuration, even when water is introduced into the second gap, the effect of suppressing the infiltration of water into one side of the structure can be further improved as compared with the second member.
Further, the sealing member of the water blocking member may be fixed at a position away from the outer edge portion of the first portion, for example. According to this configuration, for example, when the waterproof member is stored, the possibility that the sealing member comes into contact with another object (for example, a floor or a wall) can be reduced. As a result, deterioration of the sealing member during storage (for example, decrease in elastic force) can be reduced.
