Description

本発明は、止水機能を有する扉に関する。 The present invention relates to a door having a water blocking function.

従来、室内外の空気の出入りを規制して気密性を高める気密扉が知られている。このような気密扉は、室内で稼働している冷暖房における熱負荷を低減したり、室内外の遮音性を高めたり、外部からの粉塵などの室内への吹き込みを防止したりするなどの機能を有する。 Conventionally, an airtight door has been known that regulates the inflow and outflow of indoor and outdoor air to improve airtightness. Such an airtight door has functions such as reducing the heat load in the heating and cooling operating indoors, improving the sound insulation inside and outside the room, and preventing dust from being blown into the room from the outside. Have.

また、水害や火災などにおける浸水を防止する防水扉が知られている。防水扉は、扉本体と扉本体を受け入れる枠体との密着性を高めることで止水機能を発揮する。そして、扉本体と枠体との密着性を高めるための技術が提案されている（例えば、特許文献１、２を参照）。 In addition, waterproof doors that prevent flooding due to floods and fires are known. The waterproof door exerts a water blocking function by improving the adhesion between the door body and the frame body that receives the door body. Then, a technique for improving the adhesion between the door body and the frame has been proposed (see, for example, Patent Documents 1 and 2).

特開２０１５−５５０４９号公報Japanese Unexamined Patent Publication No. 2015-55049 特開２０１５−８１４４２号公報JP-A-2015-81442

一般に、防水扉には、扉の開閉に使用されるハンドルとは別に、扉本体と枠体との密着性を高めるための締め付け用のハンドルが設けられている。また、締め付け用のハンドルは、扉の戸先側と丁番側とにそれぞれ設けられている。そして、使用者は、防水扉の止水が必要になる度に、防水扉に赴き、それぞれの締め付け用のハンドルを操作する必要がある。従来の防水扉はこのように防水扉の締め付け用の各ハンドルの操作が必要となるため、防水扉の運用上の手間が無視できない。 In general, the waterproof door is provided with a handle for tightening to improve the adhesion between the door body and the frame, in addition to the handle used for opening and closing the door. Further, the tightening handles are provided on the door end side and the hinge side of the door, respectively. Then, every time the user needs to stop the water from the waterproof door, he / she needs to go to the waterproof door and operate the respective tightening handles. Since the conventional waterproof door requires the operation of each handle for tightening the waterproof door in this way, the time and effort required to operate the waterproof door cannot be ignored.

また、締め付け用の各ハンドルが操作されたときに扉本体が枠体側に略平行に押し込まれる。したがって、防水扉に使用される丁番は、このような扉本体の平行移動を許容する特殊な構造を有する。このため、一般的な丁番を用いる場合に比べて防水扉の製造コストが高くなる可能性がある。 Further, when each of the tightening handles is operated, the door body is pushed substantially parallel to the frame body side. Therefore, the hinge used for the waterproof door has a special structure that allows such translation of the door body. Therefore, the manufacturing cost of the waterproof door may be higher than that when a general hinge is used.

本件開示の技術は、上記の事情に鑑みてなされたものであり、その目的とするところは、製造コストを抑えつつ止水機能を向上することが可能な扉を提供することである。 The technology disclosed in the present disclosure has been made in view of the above circumstances, and the purpose thereof is to provide a door capable of improving the water blocking function while suppressing the manufacturing cost.

本件開示の一側面における止水機能を有する扉は、枠体と、丁番を介して枠体に取り付けられ、枠体の開口部を開閉する扉本体と、枠体に設けられ、扉本体の閉鎖状態において扉本体の周縁部に当接することで枠体と扉本体との間を水密状態にする止水部材と、扉本体の戸先側のみに設けられ、扉本体の閉鎖状態において扉本体を枠体側に押し込むことで扉本体に止水部材を圧縮させる押し込み手段とを有する。これにより、従来の気密性を確保する扉よりも扉本体と止水部材との密着性を高めつつ、従来の防水扉と比べて特殊な丁番が不要となることから製造コストを抑えることができる。 The door having a water blocking function on one side of the present disclosure is attached to the frame body via a hinge and opens and closes the opening of the frame body, and is provided on the frame body and is provided on the door body. A water blocking member that makes the space between the frame and the door body watertight by contacting the peripheral edge of the door body in the closed state, and a water blocking member provided only on the door end side of the door body, and the door body in the closed state of the door body The door body has a pushing means for compressing the water blocking member by pushing the door toward the frame body. As a result, the adhesion between the door body and the water blocking member is improved compared to the conventional door that ensures airtightness, and a special hinge is not required compared to the conventional waterproof door, so the manufacturing cost can be suppressed. it can.

さらに、扉本体は、押し込み手段によって枠体側に押し込まれたときに、止水部材に面接触で当接する。また、止水部材は非中空である。さらに、枠体は、扉本体の閉鎖状態に
おいて扉本体の外周を囲み、止水部材は枠体に沿って延伸し、止水部材の端部は枠体の四隅において互いに接合され、端部の接合面と水平面とのなす角が鋭角である構成としてもよい。また、扉本体は、板材が接合されて形成され、板材が接合される継ぎ目は、扉本体の閉鎖状態において、止水部材に対して室外側に設けられている構成としてもよい。 Further, when the door body is pushed toward the frame by the pushing means, the door body comes into contact with the water blocking member by surface contact. Further, the water blocking member is non-hollow. Further, the frame body surrounds the outer periphery of the door body in the closed state of the door body, the water blocking member extends along the frame body, and the ends of the water blocking members are joined to each other at the four corners of the frame body. The angle formed by the joint surface and the horizontal plane may be an acute angle. Further, the door body may be formed by joining the plate materials, and the seam to which the plate materials are joined may be provided on the outdoor side of the water blocking member in the closed state of the door body.

本件開示の技術によれば、製造コストを抑えつつ止水機能を向上することが可能な扉を提供することができる。 According to the technology disclosed in the present invention, it is possible to provide a door capable of improving the water blocking function while suppressing the manufacturing cost.

以下に、図面を参照して本発明の実施の形態について説明する。図１〜３に、本実施形態の止水機能を有する扉１の概略構成を示す。扉１はビル、工場、マンション、変電所などの施設に設けられる。図１は、扉１が閉鎖状態である場合に室内側から扉１を見た図を示す。図２は、図１のＡ−Ａ線による断面を示す図であり、図３は、図１のＢ−Ｂ線による断面を示す図である。扉１は扉本体１０と扉本体１０を受け入れる枠体２０を有する。扉本体１０は、枠体２０の開口部を開閉する。なお、図２および図３では、扉本体１０の一部の断面を省略している。扉本体１０および枠体２０は、ステンレススチールの板部材により形成されている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIGS. 1 to 3 show a schematic configuration of the door 1 having a water blocking function according to the present embodiment. Door 1 is provided in facilities such as buildings, factories, condominiums, and substations. FIG. 1 shows a view of the door 1 viewed from the indoor side when the door 1 is in the closed state. FIG. 2 is a diagram showing a cross section taken along the line AA of FIG. 1, and FIG. 3 is a diagram showing a cross section taken along the line BB of FIG. The door 1 has a door body 10 and a frame body 20 that receives the door body 10. The door body 10 opens and closes the opening of the frame body 20. In addition, in FIG. 2 and FIG. 3, a part of the cross section of the door body 10 is omitted. The door body 10 and the frame body 20 are formed of stainless steel plate members.

扉本体１０と枠体２０とは、３つのステンレススチール製の丁番３０によって互いに固定されている。なお、丁番３０の数や位置などは図１に示す構成に限られない。また、丁番３０は、いわゆるエアタイト扉またはセミエアタイト扉と呼ばれる扉閉鎖時に気密性が確保される扉に用いられる一般的な丁番である。 The door body 10 and the frame 20 are fixed to each other by three stainless steel hinges 30. The number and position of the hinges 30 are not limited to the configuration shown in FIG. Further, the hinge 30 is a general hinge used for a so-called airtight door or a semi-airtight door that ensures airtightness when the door is closed.

扉本体１０の内部には、鉛直方向に延伸する４本の金属製の補強部材４０が設けられている。補強部材４０の端部は、扉本体１０の上面部１０ａと下面部１０ｂとにそれぞれ接合されている。また、図３に示すように、補強部材４０は扉本体１０の水平方向における断面形状がコの字形となるように形成されている。なお、補強部材４０の数や位置などは図１に示す構成に限られない。 Inside the door body 10, four metal reinforcing members 40 extending in the vertical direction are provided. The end portion of the reinforcing member 40 is joined to the upper surface portion 10a and the lower surface portion 10b of the door body 10, respectively. Further, as shown in FIG. 3, the reinforcing member 40 is formed so that the cross-sectional shape of the door body 10 in the horizontal direction is U-shaped. The number and positions of the reinforcing members 40 are not limited to the configuration shown in FIG.

扉本体１０の戸先側にはグレモン締り装置１２０が設けられている。グレモン締り装置１２０は、ハンドル５０、ケース６０、シリンダ７０、ラッチボルト８０、ロッド棒９０、ロッド棒受け部１００を有する。以下にグレモン締り装置１２０の各部について説明する。 A Gremon tightening device 120 is provided on the door end side of the door body 10. The Gremon tightening device 120 includes a handle 50, a case 60, a cylinder 70, a latch bolt 80, a rod rod 90, and a rod rod receiving portion 100. Each part of the Gremon tightening device 120 will be described below.

扉本体１０の両側（室内側および室外側）には、扉１の開閉を行うために使用者が操作するステンレススチール製のハンドル５０がそれぞれ設けられている。使用者はハンドル５０を操作して扉本体１０と枠体２０とを密着させる。ハンドル５０はステンレススチー
ル製のケース６０に取り付けられている。ケース６０はシリンダ７０およびラッチボルト８０を備える。なお、図示を省略するが、ケース６０は、デッドボルトやシリンダ７０と接続するサムターンも備える。 Stainless steel handles 50 operated by the user to open and close the door 1 are provided on both sides (indoor side and outdoor side) of the door body 10. The user operates the handle 50 to bring the door body 10 and the frame 20 into close contact with each other. The handle 50 is attached to a stainless steel case 60. The case 60 includes a cylinder 70 and a latch bolt 80. Although not shown, the case 60 also includes a dead bolt and a thumb turn for connecting to the cylinder 70.

扉本体１０の内部において、ケース６０の上面６０ａと下面６０ｂには、ロッド棒９０の一端がそれぞれ接続されている。また、ロッド棒９０の他端は、扉本体１０の外部に突出している。それぞれのロッド棒９０は、ハンドル５０の動作に連動して、その延伸方向、すなわち扉本体１０の上下方向において移動する。 Inside the door body 10, one end of the rod rod 90 is connected to the upper surface 60a and the lower surface 60b of the case 60, respectively. Further, the other end of the rod rod 90 projects to the outside of the door body 10. Each rod rod 90 moves in the extending direction of the handle 50, that is, in the vertical direction of the door body 10.

枠体２０には、扉本体１０から突出するロッド棒９０の他端にあたる先端部９０ａを受け入れるロッド棒受け部１００が設けられている。ロッド棒受け部１００は、図２に示すように、段差１００ａが設けられている。段差１００ａが設けられていることにより、ロッド棒受け部１００は、扉本体１０の上下方向における深さが浅い部分１００ｂと深い部分１００ｃとを有する。また、深さが深い部分１００ｃは、深さが浅い部分１００ｂに対して室内側に設けられている。 The frame body 20 is provided with a rod rod receiving portion 100 that receives a tip portion 90a, which is the other end of the rod rod 90 protruding from the door body 10. As shown in FIG. 2, the rod rod receiving portion 100 is provided with a step 100a. Since the step 100a is provided, the rod rod receiving portion 100 has a shallow portion 100b and a deep portion 100c in the vertical direction of the door body 10. Further, the deep portion 100c is provided on the indoor side with respect to the shallow portion 100b.

また、図４に、本実施形態に係る枠体２０の概略構成の一例を示す。枠体２０は、扉本体１０が閉鎖状態であるときに、扉本体１０の外周を囲むようにロの字形に形成されている。また、枠体２０には、扉１が閉鎖状態であるときに扉本体１０と当接する非中空（密実）のパッキン１１０が枠体２０の溝２０ａに嵌め込まれている。パッキン１１０が止水部材の一例に相当する。なお、溝２０ａは、扉１が閉鎖状態であるときに扉本体１０の室内側の面の周縁部に対向するように設けられている。このため、扉１が閉鎖状態であるときに、パッキン１１０は扉本体１０の周縁部に当接する。 Further, FIG. 4 shows an example of a schematic configuration of the frame body 20 according to the present embodiment. The frame body 20 is formed in a square shape so as to surround the outer periphery of the door body 10 when the door body 10 is in the closed state. Further, in the frame body 20, a non-hollow (solid) packing 110 that comes into contact with the door body 10 when the door 1 is in the closed state is fitted into the groove 20a of the frame body 20. The packing 110 corresponds to an example of a water blocking member. The groove 20a is provided so as to face the peripheral edge of the indoor surface of the door body 10 when the door 1 is in the closed state. Therefore, when the door 1 is in the closed state, the packing 110 comes into contact with the peripheral edge of the door body 10.

使用者は、ハンドル５０を操作して、扉本体１０を枠体２０に設けられたパッキン１１０に当接させる。このとき、ロッド棒９０が、ハンドル５０の移動に連動して、扉本体１０の上面部１０ａと下面部１０ｂからそれぞれ突出する方向に移動する。ロッド棒９０の先端部９０ａは、ロッド棒受け部１００の深さが浅い部分１００ｂに当接する。そして、ハンドル５０の移動に連動してロッド棒９０は扉本体１０からさらに突出するように移動する。このとき、ロッド棒９０の先端部９０ａはロッド棒受け部１００の深さが浅い部分１００ｂから段差１００ａを経由して深さが深い部分１００ｃに移動する。そして、ロッド棒９０も、先端部９０ａのロッド棒受け部１００における移動に従って室内側に移動する。この結果、ロッド棒９０の移動に伴って扉本体１０も室内側に押し込まれ、扉本体１０が枠体２０に設けられたパッキン１１０を圧縮する。この結果、扉本体１０と枠体２０との間が水密状態となる。 The user operates the handle 50 to bring the door body 10 into contact with the packing 110 provided on the frame body 20. At this time, the rod rod 90 moves in the direction of protruding from the upper surface portion 10a and the lower surface portion 10b of the door body 10 in conjunction with the movement of the handle 50. The tip 90a of the rod rod 90 comes into contact with the shallow portion 100b of the rod rod receiving portion 100. Then, in conjunction with the movement of the handle 50, the rod rod 90 moves so as to further protrude from the door body 10. At this time, the tip 90a of the rod rod 90 moves from the shallow portion 100b of the rod rod receiving portion 100 to the deep portion 100c via the step 100a. Then, the rod rod 90 also moves indoors according to the movement of the tip portion 90a in the rod rod receiving portion 100. As a result, the door body 10 is also pushed into the room side as the rod rod 90 moves, and the door body 10 compresses the packing 110 provided on the frame body 20. As a result, the space between the door body 10 and the frame 20 becomes watertight.

本実施形態では、グレモン締り装置１２０が、扉本体を枠体側に押し込むことで扉本体に止水部材を圧縮させる押し込み手段の一例に相当する。なお、本実施形態では、グレモン締り装置１２０のハンドル５０が、扉１の開閉を行う機能も有する構成としている。しかし、グレモン締り装置１２０が扉本体１０の戸先側のみに設けられていれば、扉１の開閉を行うハンドルとグレモン締り装置１２０を作動させるハンドルとを別体として設けてもよい。 In the present embodiment, the Gremon tightening device 120 corresponds to an example of a pushing means for compressing the water blocking member into the door body by pushing the door body toward the frame body. In this embodiment, the handle 50 of the Gremon tightening device 120 also has a function of opening and closing the door 1. However, if the Gremon tightening device 120 is provided only on the door end side of the door body 10, the handle for opening and closing the door 1 and the handle for operating the Gremon tightening device 120 may be provided separately.

図５に、扉１が閉鎖状態であるときの扉本体１０と枠体２０に設けられたパッキン１１０との当接状態の一例を示す。図５は、図３と同様の扉本体１０、枠体２０、パッキン１１０の断面図である。図５に示すように、扉１が閉鎖状態であるとき、扉本体１０はパッキン１１０に面接触で当接する。 FIG. 5 shows an example of the contact state between the door body 10 and the packing 110 provided on the frame body 20 when the door 1 is in the closed state. FIG. 5 is a cross-sectional view of the door body 10, the frame body 20, and the packing 110 similar to those in FIG. As shown in FIG. 5, when the door 1 is in the closed state, the door body 10 comes into contact with the packing 110 by surface contact.

また、扉本体１０は、ステンレススチール製の板材により形成されている。そして、扉本体１０を形成する板材の接合部である継ぎ目１０ｃが、扉本体１０がパッキン１１０を
圧縮する際に、パッキン１１０のいわゆる止水ラインに対して室外側にある。このため、扉本体１０が浸水したときに、継ぎ目１０ｃから水が室内に漏れ出る懸念がない。 The door body 10 is made of a stainless steel plate material. The seam 10c, which is a joint portion of the plate materials forming the door body 10, is located on the outdoor side of the so-called water stop line of the packing 110 when the door body 10 compresses the packing 110. Therefore, when the door body 10 is flooded, there is no concern that water leaks into the room from the seam 10c.

本実施形態においては、上記の扉１の代わりに図６に示す扉２を用いることもできる。なお、図６に示す以外の扉２の構成は扉１と同じであるため、図示および説明を省略する。図６には、扉本体２００、枠体２１０、パッキン２２０の圧縮状態を示す。扉２においては、扉本体２００にエッジ２３０が設けられている。また、パッキン２２０は非中空であり、エッジ２３０がパッキン２２０を圧縮する際に、パッキン２２０が変形してエッジ２３０を受け入れることで、パッキン２２０とエッジ２３０とが密着した状態となる。 In the present embodiment, the door 2 shown in FIG. 6 can be used instead of the door 1 described above. Since the configuration of the door 2 other than that shown in FIG. 6 is the same as that of the door 1, illustration and description thereof will be omitted. FIG. 6 shows the compressed state of the door body 200, the frame body 210, and the packing 220. In the door 2, the door body 200 is provided with an edge 230. Further, the packing 220 is non-hollow, and when the edge 230 compresses the packing 220, the packing 220 is deformed to receive the edge 230, so that the packing 220 and the edge 230 are in close contact with each other.

エッジ２３０は、扉本体２００の枠体２１０に対向する面から所定の長さ突出する突起である。エッジ２３０は、防水扉２が閉鎖状態であるときに、枠体２１０に嵌め込まれたパッキン２２０に当接するように、扉本体２００に設けられている。エッジ２３０は溶接などによって扉本体２００と接合されている。また、エッジ２３０の接合部２３０ａは、エッジ２３０がパッキン２２０を圧縮する際に、パッキン２２０の止水ラインに対して室外側にある。このため、扉本体２００が浸水したときに、扉本体２００の内部に侵入した水が接合部２３０ａを経由して室内に漏れ出る懸念がない。 The edge 230 is a protrusion protruding by a predetermined length from the surface of the door body 200 facing the frame body 210. The edge 230 is provided on the door body 200 so as to come into contact with the packing 220 fitted in the frame body 210 when the waterproof door 2 is in the closed state. The edge 230 is joined to the door body 200 by welding or the like. Further, the joint portion 230a of the edge 230 is located on the outdoor side of the water stop line of the packing 220 when the edge 230 compresses the packing 220. Therefore, when the door body 200 is flooded, there is no concern that the water that has entered the inside of the door body 200 leaks into the room via the joint 230a.

扉１の閉鎖状態において扉本体１０とパッキン１１０とが当接する面積は、扉２の閉鎖状態においてエッジ２３０とパッキン２２０とが当接する面積よりも大きいと言える。すなわち、本実施形態において、扉１と扉２とを比較すると、扉１の扉本体１０とパッキン１１０との密着性は、扉２のエッジ２３０とパッキン２２０との密着性よりも高いと考えられる。したがって、扉１の方が扉２よりもより高い止水性能を期待できる。 It can be said that the area in which the door body 10 and the packing 110 abut in the closed state of the door 1 is larger than the area in which the edge 230 and the packing 220 abut in the closed state of the door 2. That is, in the present embodiment, when the door 1 and the door 2 are compared, it is considered that the adhesion between the door body 10 of the door 1 and the packing 110 is higher than the adhesion between the edge 230 of the door 2 and the packing 220. .. Therefore, the door 1 can be expected to have higher water stopping performance than the door 2.

図７に、本実施形態における扉１の枠体２０の溝２０ａに嵌め込まれたパッキン１１０の一部拡大図を示す。本実施形態では、パッキン１１０は、４本の直方体のパッキンが溝２０ａの四隅において互いに接合され、枠体２０と同様にロの字形に形成されている。また、パッキン１１０の素材には、シリコーンゴムに気泡を含有させたシリコーンスポンジが用いられている。図７には、枠体２０の溝２０ａの四隅のうち１つの隅におけるパッキン１１０の接合を示す。パッキン１１０の端部は、溝２０ａの隅において、接着剤により互いに接着された後に接着部分が加熱されて一体的に接合される。 FIG. 7 shows a partially enlarged view of the packing 110 fitted in the groove 20a of the frame body 20 of the door 1 in the present embodiment. In the present embodiment, the packing 110 has four rectangular parallelepiped packings joined to each other at the four corners of the groove 20a, and is formed in a square shape like the frame body 20. Further, as the material of the packing 110, a silicone sponge in which air bubbles are contained in silicone rubber is used. FIG. 7 shows the joining of the packing 110 at one of the four corners of the groove 20a of the frame body 20. The ends of the packing 110 are bonded to each other by an adhesive at the corner of the groove 20a, and then the bonded portions are heated and integrally joined.

また、図７に示すように、パッキン１１０の端部における接合面１１０ａは、水平面２００となす角度θが約４５°、すなわち、パッキン１１０の接合面１１０ａの面積が最大化されるように設定されている。なお、角度θは、止水部材の端部の接合面と水平面とのなす角の一例である。また、角度θは約４５°に限られず、接合面と水平面とのなす角が鋭角（０°＜θ＜９０°）になるように設定してもよい。本実施形態では、パッキン１１０が枠体２０の溝２０ａの四隅において接合されるため、例えば接合前に各パッキンの長さを調整するなどの変更を柔軟に行えるため、パッキン１１０を１部材としてロの字形に成形する場合に比べて設計変更がしやすいと言える。また、本実施形態におけるパッキン１１０によれば、パッキン１１０を１部材としてロの字形に成形する場合に比べて製造しやすく、製造コストの低減も期待できる。 Further, as shown in FIG. 7, the joint surface 110a at the end of the packing 110 is set so that the angle θ formed with the horizontal plane 200 is about 45 °, that is, the area of the joint surface 110a of the packing 110 is maximized. ing. The angle θ is an example of the angle formed by the joint surface at the end of the water blocking member and the horizontal plane. Further, the angle θ is not limited to about 45 °, and the angle formed by the joint surface and the horizontal plane may be set to be an acute angle (0 ° <θ <90 °). In the present embodiment, since the packing 110 is joined at the four corners of the groove 20a of the frame body 20, changes such as adjusting the length of each packing before joining can be flexibly performed. Therefore, the packing 110 is used as one member. It can be said that it is easier to change the design than when molding it into the shape of. Further, according to the packing 110 in the present embodiment, it is easier to manufacture as compared with the case where the packing 110 is formed into a square shape as one member, and a reduction in manufacturing cost can be expected.

図８に、従来の防水扉の枠体３００の溝３００ａの１つの隅におけるパッキン３１０の接合を示す。なお、溝３００ａの幅は、上記の枠体２０の溝２０ａと同じであると想定する。従来の防水扉においては、パッキン３１０は１本の棒状のパッキンであり、パッキン３１０は溝３００ａに沿って嵌め込まれているだけである。すなわち、パッキン３１０の一端の端面３１０aがパッキン３１０の他端側の側面に接しているだけであり、一体的に
接合されていない。図８に示すように、パッキン３１０の端面３１０ａは、鉛直面あるいは水平面（図中、点線にて示す）である。したがって、図７に示す接合面１１０ａの面積
に比べて、パッキン３１０の端面３１０ａの面積は小さい。このため、図８に示す枠体３００を用いる防水扉が浸水したときに、防水扉に加わる水圧が大きくなると、扉本体からパッキン３１０に加わる圧力も大きくなる結果、パッキン３１０が溝３００ａ内で変形する際にパッキン３１０の端面３１０ａとパッキン３１０との間に隙間が生じ、当該隙間に水が進入して室内側に水が漏れ出る可能性がある。 FIG. 8 shows the joining of the packing 310 at one corner of the groove 300a of the frame body 300 of the conventional waterproof door. It is assumed that the width of the groove 300a is the same as the groove 20a of the frame body 20 described above. In the conventional waterproof door, the packing 310 is a single rod-shaped packing, and the packing 310 is only fitted along the groove 300a. That is, the end surface 310a at one end of the packing 310 is only in contact with the side surface on the other end side of the packing 310, and is not integrally joined. As shown in FIG. 8, the end face 310a of the packing 310 is a vertical plane or a horizontal plane (indicated by a dotted line in the figure). Therefore, the area of the end surface 310a of the packing 310 is smaller than the area of the joint surface 110a shown in FIG. Therefore, when the waterproof door using the frame body 300 shown in FIG. 8 is flooded, if the water pressure applied to the waterproof door increases, the pressure applied from the door body to the packing 310 also increases, and as a result, the packing 310 deforms in the groove 300a. At that time, a gap is generated between the end surface 310a of the packing 310 and the packing 310, and there is a possibility that water may enter the gap and leak to the indoor side.

これに対し、本実施形態においては、枠体２０の溝２０ａの四隅におけるパッキン１１０の接合面１１０ａの面積は、図８に示す端面３１０ａの面積よりも大きく、パッキン１１０は接合面１１０ａで互いに接合されている。したがって、扉１が浸水して扉本体１０からパッキン１１０に加わる圧力が大きくなってパッキン１１０が溝２０ａ内で変形したときに、パッキン１１０の接合部に隙間が生じる可能性が図８に示す場合よりも低いと言える。 On the other hand, in the present embodiment, the area of the joint surface 110a of the packing 110 at the four corners of the groove 20a of the frame body 20 is larger than the area of the end surface 310a shown in FIG. 8, and the packing 110 is joined to each other at the joint surface 110a. Has been done. Therefore, when the door 1 is flooded and the pressure applied from the door body 10 to the packing 110 increases and the packing 110 is deformed in the groove 20a, there is a possibility that a gap may be formed at the joint portion of the packing 110, as shown in FIG. It can be said that it is lower than.

ここで、本実施形態に係る扉１、２の止水性能を確認するため、扉１、２を閉鎖状態にして浸水させたときの漏水量を計測する試験を行った。なお、扉１、２に用いられている扉本体とパッキンの密着性を比較するため、パッキンが中空である場合における扉本体あるいはエッジとパッキンとの密着性が確保される場合についても同様の試験を行った。なお、試験水位は１ｍまたは２ｍとした。また、以下の説明において、エッジによって扉本体とパッキンとの密着性が確保される場合を「エッジ方式」、扉本体がパッキンに面接触で当接することにより扉本体とパッキンとの密着性が確保される場合を「面タッチ方式」と称する。 Here, in order to confirm the water stopping performance of the doors 1 and 2 according to the present embodiment, a test was conducted to measure the amount of water leakage when the doors 1 and 2 were closed and flooded. In order to compare the adhesion between the door body and the packing used for the doors 1 and 2, the same test is performed when the adhesion between the door body or the edge and the packing is ensured when the packing is hollow. Was done. The test water level was 1 m or 2 m. Further, in the following description, the case where the adhesion between the door body and the packing is ensured by the edge is the "edge method", and the adhesion between the door body and the packing is ensured by the door body contacting the packing by surface contact. This case is referred to as a "face touch method".

具体的には、（１）エッジ方式でパッキンは中空である場合（２）エッジ方式でパッキンは非中空である場合（３）面タッチ方式でパッキンは中空である場合（４）面タッチ方式でパッキンは非中空である場合の４つの構成についてそれぞれ漏水量を計測した。なお、本実施形態の扉１の扉本体１０とパッキン１１０の構成は（４）の場合に対応する。また、扉２の扉本体２００のエッジ２３０とパッキン２２０の構成は（２）の場合に対応する。 Specifically, (1) when the packing is hollow by the edge method (2) when the packing is non-hollow by the edge method (3) when the packing is hollow by the surface touch method (4) when the packing is hollow by the surface touch method The amount of water leakage was measured for each of the four configurations when the packing was non-hollow. The configuration of the door body 10 and the packing 110 of the door 1 of the present embodiment corresponds to the case of (4). Further, the configuration of the edge 230 and the packing 220 of the door body 200 of the door 2 corresponds to the case (2).

上記の試験の結果、漏水量は、（１）の場合よりも（２）の場合の方が漏水量が少なく、（３）の場合よりも（４）の場合の方が漏水量が少ないことがわかった。このことから、パッキンについては、中空である場合よりも非中空である場合の方が、漏水量が少なくなると言える。また、（１）の場合よりも（３）の場合の方が漏水量が少なく、（２）の場合よりも（４）の場合の方が漏水量が少ないこともわかった。このことから、扉本体とパッキンとの当接は、エッジ方式よりも面タッチ方式の方が、漏水量が少なくなると言える。 As a result of the above test, the amount of water leakage is smaller in the case of (2) than in the case of (1), and less in the case of (4) than in the case of (3). I understood. From this, it can be said that the amount of water leakage of the packing is smaller when it is non-hollow than when it is hollow. It was also found that the amount of water leakage was smaller in the case of (3) than in the case of (1), and was smaller in the case of (4) than in the case of (2). From this, it can be said that the amount of water leakage is smaller in the surface touch method than in the edge method for the contact between the door body and the packing.

そして、本発明に係る業界において基準値０．０２ｍ3／ｈ以下（試験水位１ｍ、２ｍ
）であれば防水扉と取り扱われているところ、上記の（４）の場合によれば基準値に比べて極めて少ない０．００２ｍ3／ｈ（試験水位１ｍ）、０．００１ｍ3／ｈ（試験水位２ｍ）という結果が得られた。以上より、本実施形態に係る扉１の扉本体１０とパッキン１１０の構成は、上記の他の扉本体およびパッキンの構成に比べてより高い止水機能を発揮すると考えられる。 Then, in the industry according to the present invention, the standard value is 0.02 m 3 / h or less (test water level 1 m, 2 m).
If) where being handled waterproof door, very small in comparison with the reference value, according to the case of the above (4) 0.002m 3 / h (test level 1m), 0.001m 3 / h (Test The result was that the water level was 2 m). From the above, it is considered that the configuration of the door body 10 and the packing 110 of the door 1 according to the present embodiment exhibits a higher water stopping function than the configurations of the other door body and the packing described above.

以上のように、本実施形態に係る止水機能を有する扉によれば、扉本体の押し込み手段の一例であるグレモン締り装置を戸先側のみに設けるだけで扉本体とパッキンの密着性を確保しつつ必要十分な止水機能を実現することができる。したがって、本実施形態に係る止水機能を有する扉によれば、従来の防水扉のように、戸先側と丁番側の双方に高価な締付け専用のグレモン締り装置を設置する必要がない。また、従来の防水扉のように戸先側と丁番側の双方に締付け専用のグレモン締り装置を設置する必要がないため、枠体側に対
して扉本体を平行に押し込むことを可能とする非常に高価かつ特殊な丁番も使用する必要がなく、通常の気密扉に使用される比較的廉価な丁番を使用することができる。よって、本実施形態に係る止水機能を有する扉によれば、従来の防水扉と同等の防水（止水）機能を担保しつつ、製造コストを低減することができる。 As described above, according to the door having the water blocking function according to the present embodiment, the adhesion between the door body and the packing is ensured only by providing the Gremon tightening device, which is an example of the pushing means of the door body, only on the door end side. While doing so, it is possible to realize the necessary and sufficient water stopping function. Therefore, according to the door having the water blocking function according to the present embodiment, unlike the conventional waterproof door, it is not necessary to install an expensive glemmon tightening device dedicated to tightening on both the door end side and the hinge side. In addition, unlike conventional waterproof doors, it is not necessary to install a dedicated tightening device for tightening on both the door end side and the hinge side, so it is possible to push the door body parallel to the frame body side. It is not necessary to use expensive and special hinges, and relatively inexpensive hinges used for ordinary airtight doors can be used. Therefore, according to the door having a water blocking function according to the present embodiment, it is possible to reduce the manufacturing cost while ensuring the waterproof (water stopping) function equivalent to that of the conventional waterproof door.

以上が本実施形態に関する説明であるが、上記の扉１、２の構成は、上記の実施形態に限定されるものではなく、本発明の技術的思想と同一性を失わない範囲内において種々の変更が可能である。例えば、扉１、２が浸水したときに水位がサムターンの配置位置よりも高くなることが想定される場合は、サムターンから室内に水が漏れ出ることを防止するためにサムターンに止水機能を付加してもよい。なお、サムターンに止水機能を付加する場合は、周知の技術を用いて実現できるため、ここでは詳細な説明は省略する。 The above is the description of the present embodiment, but the configuration of the doors 1 and 2 is not limited to the above embodiment, and various types are provided within a range that does not lose the identity with the technical idea of the present invention. It can be changed. For example, if it is assumed that the water level will be higher than the position where the thumb turn is placed when the doors 1 and 2 are flooded, a water stop function is added to the thumb turn to prevent water from leaking into the room from the thumb turn. You may. It should be noted that the case of adding the water blocking function to the thumb turn can be realized by using a well-known technique, and therefore detailed description thereof will be omitted here.
