Description

本発明は、バルコニー等の腰壁に取り付けられた通気水切に関する。 The present invention relates to a vent drainer attached to a waist wall such as a balcony.

建物の劣化対策等級を高めるには、屋根扱いとなるバルコニー（屋上を含む）に何らかの小屋換気設備を必要とする。多少の漏水リスクを含む方法であれば、換気ガラリや笠木裏側で換気をとることも可能であるが、長期耐久性を視野に、漏水リスクを限りなくゼロに近づけるには、高次元の止水換気装置が必要であった。それに相当する従来の技術は、独立した換気口をバルコニー近傍の壁面に設けることで意匠性に影響を与える、突起が避けられないことから足掛かりになる、壁体内に納まり交換が困難である、高価である、という側面を有していた。 In order to raise the grade of measures against deterioration of buildings, some kind of hut ventilation system is required for balconies (including rooftops) that are handled as roofs. If the method involves some risk of water leakage, it is possible to ventilate through the ventilation gallery or behind the caps, but in order to bring the risk of water leakage to zero as much as possible from the perspective of long-term durability, a high-dimensional water stoppage is required. A ventilator was needed. The corresponding conventional technology has an independent ventilation opening on the wall near the balcony, which affects the design, becomes a stepping stone because protrusions are unavoidable, is difficult to replace within the wall, and is expensive It had the aspect of being.

建物において、外壁材と下地との間には壁体内への水の侵入を防止する水切り構造が設けられる。水切り構造として一般的なものは、外壁材と下地との間から外部へ突出した水切り板金を設けるが、この水切り板金は風雨にさらされて劣化する。このため、水切りが劣化した際に取り替えができるように、取り外し可能にした構造がある（例えば、特許文献１〜４参照）。取り外しの際、従来は板金状の水切り板の端部を変形させて、水切り板固定部から取り外していた。 In the building, a draining structure for preventing water from entering the wall is provided between the outer wall material and the base. A common draining structure is provided with a draining sheet metal projecting from between the outer wall material and the base, and this draining sheet metal is deteriorated by exposure to wind and rain. For this reason, there exists a structure which made it removable so that it can replace | exchange when draining deteriorates (for example, refer patent documents 1-4). At the time of removal, conventionally, the end portion of the sheet metal-like draining plate is deformed and removed from the draining plate fixing portion.

また、水切りを設置する外壁材と下地との空間に通気穴を形成し、通気性能を持たせた通気水切がある（例えば、特許文献２〜６参照）。このような通気水切は通気性能を有する点で優れるが、雨水の吹き込み等により通気穴から雨水が侵入するといった問題がある。このため、通気穴から雨水を侵入させないように通気穴に弁を取り付けたものがある（例えば、特許文献５〜６参照）。 In addition, there is a vent drainer in which a vent hole is formed in the space between the outer wall material on which the drainer is installed and the base so that the vent performance is provided (see, for example, Patent Documents 2 to 6). Such a drainage drain is excellent in that it has ventilation performance, but there is a problem that rainwater enters from the vent hole due to rainwater blowing. For this reason, there exists what attached the valve to the vent hole so that rainwater may not enter from the vent hole (for example, refer to patent documents 5 to 6).

しかしながら、特許文献１、２ではバネ系止体（取付金具）を通りよくかつ、各個ビスで取り付けることを要し、組立作業が手間となる問題があった。特許文献３、４では通気の為には水切り本体及び固定基体に通気穴を設けることを要し、それぞれについて、一般にプレス金型等の設備を要することになり、通気穴を開ける加工により製作が容易に出来ない問題があった。また、特許文献５、６については、耐久性の観点から開閉弁は容易に交換し得ることが望ましい。 However, in Patent Documents 1 and 2, there is a problem that the assembly work is troublesome because it is necessary to pass through the spring-type stationary body (mounting bracket) and to be attached with individual screws. In Patent Documents 3 and 4, for ventilation, it is necessary to provide a vent hole in the draining main body and the fixed base, and each of them generally requires equipment such as a press die, which is manufactured by processing to open the vent hole. There was a problem that could not be easily done. In Patent Documents 5 and 6, it is desirable that the on-off valve can be easily replaced from the viewpoint of durability.

本発明は、メンテナンスが容易で且つ風雨が強い場合において雨水の侵入を防止する通気水切を提供することを目的とする。 It is an object of the present invention to provide a ventilating drainer that prevents rainwater from entering when maintenance is easy and wind and rain are strong.

図を用いて本願発明の実施形態を説明する。 Embodiments of the present invention will be described with reference to the drawings.

（通気水切１の概略構成）
まず、通気水切１の概略構成及び周辺構成を説明する。図１は通気水切の全体構成を示す断面図であり、（ａ）が建物のうち通気水切を取り付ける場所を示す概略図、（ｂ）が通気水切の全体断面図である。図２は通気水切の全体構成を示す斜視図である。 (Schematic configuration of venting drainer 1)
First, a schematic configuration and a peripheral configuration of the ventilating drainer 1 will be described. 1A and 1B are cross-sectional views showing the overall configuration of the ventilating drain, wherein FIG. 1A is a schematic diagram showing a place where the venting drainage is attached in a building, and FIG. FIG. 2 is a perspective view showing the entire structure of the ventilating water drainer.

図１（ａ）に示すように、通気水切１は、例えば、建物２の小屋裏５上部のバルコニー３の外壁４内部に設けると好適である。通気水切１が通気性を有することで、雨水の侵入を防止しつつ、バルコニー３から小屋裏５に空気を取り入れることができる。尚、通気水切１の設置場所はこの場所に限るものではない。 As shown in FIG. 1 (a), the ventilating drainer 1 is preferably provided inside the outer wall 4 of the balcony 3 at the upper part of the hut 5 of the building 2, for example. Since the ventilation drainer 1 has air permeability, air can be introduced from the balcony 3 to the hut back 5 while preventing rainwater from entering. In addition, the installation location of the ventilator 1 is not limited to this location.

図１（ｂ）及び図２に示すように、通気水切１は、腰壁６と下地７との間に形成される通気穴８に取り付けられる。通気水切１は、雨水を通気穴８から遠ざけるように、外部下方に傾斜した水切片１１が形成される水切カバー１０と、風が吹き込むと閉まる開閉弁１２を有する。この構成により、通気水切１の内部への雨水の侵入を防ぐ。また、通気水切１は、壁面に取り付けるための取付基材２０を有する。取付基材２０は下地７の上に載置される載置部２０ａと、腰壁６の方向に立ち上がる腰壁６内に固定される板状部２０ｂとを一体的に有する。 As shown in FIGS. 1B and 2, the ventilating drainer 1 is attached to a vent hole 8 formed between the waist wall 6 and the base 7. The vent drainer 1 has a drainer cover 10 formed with a water slice 11 inclined downward to the outside so as to keep rainwater away from the vent hole 8, and an on-off valve 12 that closes when wind blows. This configuration prevents rainwater from entering the inside of the ventilating drainer 1. Moreover, the ventilating drainer 1 has the attachment base material 20 for attaching to a wall surface. The mounting base material 20 integrally includes a placement portion 20 a placed on the base 7 and a plate-like portion 20 b fixed in the waist wall 6 rising in the direction of the waist wall 6.

尚、本実施形態の通気穴８は、図１（ｂ）に示すように、通気層８ａの最下端に位置し水平方向に延びる長穴である。通気層８ａは、外装材６ａの裏面方向に形成される空間である。通気層８ａは、外装材６ａの裏面の防水シート６ｂと防水層７ｂとの間に形成される。 In addition, the ventilation hole 8 of this embodiment is an elongate hole located in the lowest end of the ventilation layer 8a and extending in a horizontal direction, as shown in FIG.1 (b). The ventilation layer 8a is a space formed in the back surface direction of the exterior material 6a. The ventilation layer 8a is formed between the waterproof sheet 6b on the back surface of the exterior material 6a and the waterproof layer 7b.

通気水切１は、腰壁６と下地７とに渡り取り付く。ここで、腰壁６と下地７の構成を説明する。腰壁６は、最外層を形成する外装材６ａと、防水性を有する防水シート６ｂと、外装材下地６ｃと、通気水切１を取り付けるための取付下地６ｄと、を有する。一方、下地７は、スラグ石膏板等で構成された立ち上がり壁７ａの外部及び上部にＦＲＰ等による防水層７ｂを形成した構造である。 The ventilating drainer 1 is attached to the waist wall 6 and the base 7. Here, the configuration of the waist wall 6 and the base 7 will be described. The waist wall 6 includes an exterior material 6 a that forms the outermost layer, a waterproof waterproof sheet 6 b, an exterior material base 6 c, and an attachment base 6 d for attaching the ventilating drainer 1. On the other hand, the base 7 has a structure in which a waterproof layer 7b made of FRP or the like is formed on the outside and upper part of the rising wall 7a made of slag gypsum board or the like.

尚、外装材下地６ｃとしては、好ましくは例えば特開２０００−１６０７３２号公報に記載のパネル部材と同様の構成を備えるものがよい。当該パネル部材では、間隔をおいて平行に配置された複数の表側帯状小幅板と、間隔をおいて平行に配置された複数の裏側帯状小幅板とを互いに交差させた状態で接合一体化してなる壁下地パネルが用いられている。このような壁下地パネルは、各帯状小幅板間の間隔部分を経て空気を上昇させることにより十分な通気を確保することが可能な通気層を、外壁仕上げ材の背面側に形成することができ、また相反する方向に傾斜させた各帯状小幅板を筋交いのように機能させて、構造用耐力部材としての所望の強度が得られるようになっている。当該パネルを設けることによって、図１（ｂ）に示すように通気層８ａを形成することができる。 The exterior material base 6c preferably has the same configuration as the panel member described in, for example, Japanese Patent Application Laid-Open No. 2000-160732. In the panel member, a plurality of front side belt-like narrow plates arranged in parallel at intervals and a plurality of back side belt-like narrow plates arranged in parallel at intervals are joined and integrated in a state of crossing each other. Wall base panel is used. Such a wall foundation panel can form a ventilation layer on the back side of the outer wall finishing material that can ensure sufficient ventilation by raising the air through the space between each strip-shaped narrow plate. In addition, each band-shaped narrow plate inclined in the opposite direction is caused to function like a brace so that a desired strength as a structural strength member can be obtained. By providing the panel, the ventilation layer 8a can be formed as shown in FIG.

ここで、通気層８ａの形成方法はこのようなパネルを用いるものに限らない。例えば、その他の通気層８ａの形成方法として、前記防水層７ｂの裏面に合板又は火山性ガラス質複層板等の耐力面材を配置し、防水層７ｂと外装材６ａの間に縦胴縁を用いて通気層８ａを確保してもよい。 Here, the method of forming the ventilation layer 8a is not limited to using such a panel. For example, as another method for forming the air-permeable layer 8a, a load bearing surface material such as a plywood or a volcanic glassy multilayer board is disposed on the back surface of the waterproof layer 7b, and a vertical trunk edge is provided between the waterproof layer 7b and the exterior material 6a. The air-permeable layer 8a may be secured using

この構成により通気水切１は、取付基材２０の載置部２０ａが下地７上に載置され、その下方が固定される。また、通気水切１は、腰壁６の防水シート６ｂと外装材下地６ｃとの間に取付基材２０の板状部２０ｂが挟み込まれ、その水平方向が固定される。尚、腰壁６の外装材６ａは、取付基材２０の外装材受部２０ｃに載置される。 With this configuration, in the ventilating drainer 1, the placement portion 20a of the mounting base 20 is placed on the base 7, and the lower part thereof is fixed. Further, in the ventilating drainer 1, the plate-like portion 20b of the mounting base material 20 is sandwiched between the waterproof sheet 6b of the waist wall 6 and the exterior material base 6c, and the horizontal direction thereof is fixed. Note that the exterior material 6 a of the waist wall 6 is placed on the exterior material receiving portion 20 c of the attachment base material 20.

（通気水切１の詳細構成）
図３を用いて通気水切１の詳細構成を説明する。図３は通気水切の各部構成を示す断面図であり、（ａ）は通気水切１の完成図、（ｂ）は通気水切１を各部に分解した図である。 (Detailed structure of ventilating drainer 1)
The detailed structure of the ventilating drainer 1 will be described with reference to FIG. FIG. 3 is a cross-sectional view showing the configuration of each part of the ventilating drain, where (a) is a completed drawing of the venting drainer 1 and (b) is an exploded view of the venting drainer 1 into parts.

図３（ａ）に示すように、通気水切１は、雨水の侵入を防ぐ水切カバー１０と、壁面に取り付けるための取付基材２０と、水切カバー１０と取付基材２０とを連結し通気孔２２と水切カバー１０とを所定間隔離隔させるためのブラケット３０から構成される。水切カバー１０、取付基材２０、ブラケット３０はアルミニウム等、軽量で、風雨に強く、劣化しにくい材料であることが望ましい。 As shown in FIG. 3 (a), the ventilating drainer 1 is formed by connecting a draining cover 10 for preventing rainwater from entering, a mounting base material 20 for mounting on a wall surface, the draining cover 10 and the mounting base material 20, and a vent hole. And a bracket 30 for separating the drain cover 10 and the drain cover 10 from each other by a predetermined distance. The drainage cover 10, the mounting base material 20, and the bracket 30 are desirably made of a material such as aluminum that is lightweight, resistant to wind and rain, and hardly deteriorates.

図３（ｂ）に示すように、水切カバー１０は、下に行くに連れて内側から外側方向に傾斜した水切片１１を有する。 As shown in FIG. 3 (b), the drain cover 10 has a water section 11 that is inclined from the inside to the outside as it goes down.

また、水切片１１の上端である一端部に嵌合凸部１３が形成され、水切片１１の下端である他端部の内側に開閉弁１２が形成される。開閉弁１２の弁部１２ａは樹脂の押出成形等により作られ、そのヒンジ部１２ｂは軟質樹脂によって作られることが望ましい。この構造によって、弁部１２ａの開閉が行われる。開閉動作については後述する。 In addition, a fitting convex portion 13 is formed at one end that is the upper end of the water slice 11, and an on-off valve 12 is formed inside the other end that is the lower end of the water slice 11. It is desirable that the valve portion 12a of the on-off valve 12 is made by resin extrusion or the like, and the hinge portion 12b is made of a soft resin. With this structure, the valve portion 12a is opened and closed. The opening / closing operation will be described later.

水切カバー１０は、水切片１１の内側中央部にブラケット係止部１４を有し、ブラケット３０に対して係止される構造を有する。また、水切片１１の内側上部に下方に開口した部材保持部１５を有する。部材保持部１５には、例えば、通気水切１を防火仕様にするときに、不燃性体積膨張材を挿入することができる。 The drainer cover 10 has a bracket locking portion 14 at the inner central portion of the water slice 11 and has a structure that is locked to the bracket 30. Moreover, the member holding | maintenance part 15 opened below on the inner upper part of the water slice 11 is provided. For example, a non-flammable volumetric expansion material can be inserted into the member holding portion 15 when the ventilating drainer 1 is fireproof.

取付基材２０は、腰壁６と下地７に水切カバー１０を取り付けるための部材であり、上述のように、載置部２０ａ、板状部２０ｂ、外装材受部２０ｃを有する。 The attachment base material 20 is a member for attaching the drainage cover 10 to the waist wall 6 and the base 7, and includes the placement portion 20a, the plate-like portion 20b, and the exterior material receiving portion 20c as described above.

取付基材２０には、外装材受部２０ｃの付け根部分の反対面には嵌合凸部１３と嵌合する嵌合凹部２１が形成される。嵌合凹部２１下方に腰壁６に形成される通気穴８と連通する通気孔２２が形成される。通気孔２２は縦長等に開口した複数のスリット孔とすることが好ましい（図４参照）。これは、長手方向の全てを開口としてしまうと、ネズミ等の小動物が侵入するため、これを防止するためである。 A fitting recess 21 that fits with the fitting protrusion 13 is formed on the attachment base 20 on the opposite surface of the base portion of the exterior material receiving portion 20c. A vent hole 22 communicating with the vent hole 8 formed in the waist wall 6 is formed below the fitting recess 21. The vent hole 22 is preferably a plurality of slit holes opened vertically or the like (see FIG. 4). This is to prevent a small animal such as a mouse from invading the entire longitudinal direction as an opening.

取付基材２０の下端には開閉弁１２の弁部１２ａを受ける弁受部２３が形成される。また、ブラケット３０を取り付けるために、通気孔２２の上方に第一ブラケット係止部２４が形成され、通気孔２２の下方で弁受部２３の上部には第二ブラケット係止部２５が形成される。 A valve receiving portion 23 that receives the valve portion 12 a of the on-off valve 12 is formed at the lower end of the mounting base material 20. In order to attach the bracket 30, a first bracket locking portion 24 is formed above the vent hole 22, and a second bracket locking portion 25 is formed below the vent hole 22 and above the valve receiving portion 23. The

尚、載置部２０ａの下面には水密材４１が配設される。水密材４１は下地７に当接し、通気水切１と下地７との取り合いから内部への水の侵入を防ぐ。水密材４１の材質としては透水性を有する半独立発泡のＥＰＤＭ発泡体等が好ましい。 A watertight material 41 is disposed on the lower surface of the mounting portion 20a. The watertight material 41 abuts on the base 7 and prevents water from entering into the interior from the contact between the ventilating drainer 1 and the base 7. As the material of the watertight material 41, semi-independent foamed EPDM foam having water permeability is preferable.

ブラケット３０は、その断面が傾斜して前方に張り出す張出部３０ａと、張出部前端から垂下する垂下部３０ｂと、他部材との係合や弁に当接する作用部３０ｃとから構成される。ブラケット３０は他部材と連結するための部材であるため、複数の爪状の係止部が形成される。 The bracket 30 is composed of an overhanging portion 30a that has an inclined cross section and projects forward, a drooping portion 30b that hangs down from the front end of the overhanging portion, and an action portion 30c that engages with other members and abuts against a valve. The Since the bracket 30 is a member for connecting to other members, a plurality of claw-shaped locking portions are formed.

ブラケット３０は通気水切１の長手方向に複数配設固定される。１つのブラケット３０は係止部を少なくとも３つ有する。まず、それぞれ、取付基材２０の第一ブラケット係止部２４及び第二ブラケット係止部２５に対して係止される、第一係止部３１と第二係止部３２とを有する。第一係止部３１はブラケット３０の後方（図中左側方向）上部に形成され、第二係止部３２はブラケット３０の前方（図中右側方向）下部に形成される。また、水切カバー１０のブラケット係止部１４に対して係止される第三係止部３３を有する。第三係止部３３は、ブラケット３０の前方で且つ上方に突出するように形成される。 A plurality of brackets 30 are arranged and fixed in the longitudinal direction of the ventilating drainer 1. One bracket 30 has at least three locking portions. First, it has the 1st latching | locking part 31 and the 2nd latching | locking part 32 latched with respect to the 1st bracket latching | locking part 24 and the 2nd bracket latching | locking part 25 of the attachment base material 20, respectively. The first locking portion 31 is formed at the rear (left side in the drawing) upper portion of the bracket 30, and the second locking portion 32 is formed at the front (right side in the drawing) lower portion of the bracket 30. Moreover, it has the 3rd latching | locking part 33 latched with respect to the bracket latching | locking part 14 of the drainage cover 10. FIG. The third locking portion 33 is formed so as to protrude forward and upward of the bracket 30.

また、張出部３０ａ上面に、上方に開口したクッション材保持部３４を有する。クッション材保持部３４は、クッション材４２を保持する。そして、クッション材４２は水切カバー１０に圧接される。即ち、図３（ａ）に示すように、ブラケット３０は水切カバー１０との間のクッション材４２を介して圧接される。このようにブラケット３０にクッション材４２があることにより、水切カバー１０のがたつきや横ずれを防止することができる。 Moreover, it has the cushion material holding | maintenance part 34 opened upwards on the upper surface of the overhang | projection part 30a. The cushion material holding part 34 holds the cushion material 42. Then, the cushion material 42 is pressed against the drain cover 10. That is, as shown in FIG. 3A, the bracket 30 is pressed against the drainage cover 10 via the cushion material 42. As described above, the bracket 30 has the cushion material 42, so that the drainage cover 10 can be prevented from rattling or lateral displacement.

張出部３０ａの下部には、下方に開口した部材保持部３５を有する。部材保持部３５には、例えば通気水切１を防火仕様にする際に不燃性体積膨張材を挿入する。 The lower part of the overhang | projection part 30a has the member holding part 35 opened below. For example, a non-combustible volume expansion material is inserted into the member holding portion 35 when the ventilating drainer 1 is fireproof.

作用部３０ｃの下端には、取付基材２０の弁受部２３に当接するストッパー３６が形成される。ストッパー３６は弁受部２３よりも通気水切１の通気通路Ｗ内部側に突出しているため、開閉弁１２の通気通路Ｗ内部への入り込みを防止することができる。 At the lower end of the action portion 30c, a stopper 36 that abuts on the valve receiving portion 23 of the mounting base 20 is formed. Since the stopper 36 protrudes to the inside of the ventilation passage W of the ventilating drain 1 from the valve receiving portion 23, it is possible to prevent the on-off valve 12 from entering the ventilation passage W.

（通気水切１の組立）
図４を用いて通気水切１の組立について説明する。図４は通気水切の取付構成を示す斜視図であり、（ａ）が取付基材２０にブラケット３０を取り付けた状態、（ｂ）がブラケット３０に水切カバー１０を取り付けた状態である。 (Assembly of ventilation drainer 1)
The assembly of the ventilating drainer 1 will be described with reference to FIG. FIGS. 4A and 4B are perspective views showing an aeration drainage mounting configuration, in which FIG. 4A shows a state where the bracket 30 is attached to the attachment base material 20, and FIG. 4B shows a state where the drainage cover 10 is attached to the bracket 30.

通気水切１を組立てる際は、まず図４（ａ）に示すように、取付基材２０に対して複数のブラケット３０を所定間隔で取付ける。次に図４（ｂ）に示すように、全てのブラケット３０に対して水切カバー１０を取付ける。 When assembling the ventilation drainer 1, first, as shown in FIG. 4A, a plurality of brackets 30 are attached to the attachment base material 20 at a predetermined interval. Next, as shown in FIG. 4B, the drain cover 10 is attached to all the brackets 30.

具体的には、図４に示すように、まず、取付基材２０の第一ブラケット係止部２４と第二ブラケット係止部２５に対して、それぞれブラケット３０の第一係止部３１と第二係止部３２とを係止する。次に図４（ｂ）に示すように、水切カバー１０の嵌合凸部１３を取付基材２０の嵌合凹部２１に嵌入して水切カバー１０の上部を回動可能に保持し、次に水切カバー１０のブラケット係止部１４をブラケット３０の第三係止部３３と係止させる。これにより通気水切１の組立て作業が完了する。水切カバー１０の交換の際は、水切カバー１０の動作を逆にすればよい。 Specifically, as shown in FIG. 4, first, with respect to the first bracket locking portion 24 and the second bracket locking portion 25 of the mounting base material 20, the first locking portion 31 and the second bracket locking portion 25 of the bracket 30, respectively. The two locking portions 32 are locked. Next, as shown in FIG. 4 (b), the fitting convex portion 13 of the draining cover 10 is fitted into the fitting concave portion 21 of the mounting base material 20, and the upper portion of the draining cover 10 is rotatably held. The bracket locking portion 14 of the drainage cover 10 is locked with the third locking portion 33 of the bracket 30. Thereby, the assembly work of the ventilating drainer 1 is completed. When the drain cover 10 is replaced, the operation of the drain cover 10 may be reversed.

このように、通気水切１は、取付基材２０に対してブラケット３０を係止によって固定している。このため、容易に取り付けや交換をすることができる。また、通気水切１の長手方向の複数箇所に分けてブラケット３０が取り付くため、通気通路Ｗを長手方向にわたって塞ぐことがなく、空気の通りを維持することができる。 As described above, the ventilating drainer 1 fixes the bracket 30 to the mounting base 20 by locking. For this reason, attachment and replacement can be easily performed. Moreover, since the bracket 30 is attached to a plurality of portions in the longitudinal direction of the ventilating drainer 1, the air passage can be maintained without blocking the ventilation passage W over the longitudinal direction.

また、水切カバー１０は、通気孔２２の上下に係止されるブラケット３０を介して取付基材２０に取り付く。このため、取付基材２０の通気孔２２を塞ぐ位置に取付部材等を配設する必要がない。このため、通気孔２２を塞ぐことなく、水切カバー１０を取付基材２０に取り付けることができる。 Further, the drain cover 10 is attached to the mounting base 20 via a bracket 30 that is locked above and below the vent hole 22. For this reason, it is not necessary to arrange | position an attachment member etc. in the position which plugs the ventilation hole 22 of the attachment base material 20. FIG. For this reason, the drain cover 10 can be attached to the attachment base material 20 without blocking the vent hole 22.

また、通気水切１の外観を形成する水切カバー１０は、取付基材２０及びブラケット３０に対して着脱可能に構成される。このように着脱可能に構成し、交換が可能な構成とすると、経年劣化や衝撃等により水切カバー１０が傷んだ場合、新しいものと容易に交換することができる。このため、外観に優れる通気水切１とすることができる。 Further, the drain cover 10 that forms the appearance of the vent drain 1 is configured to be detachable from the mounting base 20 and the bracket 30. When the drainage cover 10 is configured to be detachable and replaceable as described above, the drainage cover 10 can be easily replaced with a new one when the drainage cover 10 is damaged due to aging or impact. For this reason, it can be set as the ventilation drainer 1 which is excellent in an external appearance.

また、開閉弁１２は、その交換が容易となるように、水切カバー１０に取り付けられる。 Moreover, the on-off valve 12 is attached to the drain cover 10 so that the exchange is easy.

（開閉弁１２の動作）
図５を用いて開閉弁１２の動作について説明する。図５は通気水切の開閉弁の動作を示す断面図であり、（ａ）が弁が開いた状態、（ｂ）が弁が閉じた状態を示す。 (Operation of on-off valve 12)
The operation of the on-off valve 12 will be described with reference to FIG. FIG. 5 is a cross-sectional view showing the operation of the on / off valve for venting water, where (a) shows a state where the valve is open and (b) shows a state where the valve is closed.

図５（ａ）に示すように、風が強くない通常時は開閉弁１２が開いた状態になっている。図５（ｂ）に示すように、風が強くなると、風によって開閉弁１２のヒンジ部１２ｂを回動軸として弁部１２ａが押し上げられる。押し上げられた弁部１２ａは、取付基材２０の弁受部２３に当接することで通気通路Ｗの開口を閉鎖する。また、取付基材２０の弁受部２３の前方には、前方下方に突出するブラケット３０のストッパー３６がある。この構成により、更に風が強くなったときでも、ストッパー３６が弁部１２ａの上昇を押さえるため、弁部１２ａがめくり上がって通気通路Ｗに入ってしまうことがない。 As shown in FIG. 5 (a), the on-off valve 12 is open during normal times when the wind is not strong. As shown in FIG. 5B, when the wind becomes strong, the valve portion 12a is pushed up by the wind with the hinge portion 12b of the on-off valve 12 as a rotation axis. The pushed-up valve part 12a closes the opening of the ventilation passage W by contacting the valve receiving part 23 of the mounting base 20. Further, in front of the valve receiving portion 23 of the mounting base member 20, there is a stopper 36 of the bracket 30 that protrudes forward and downward. With this configuration, even when the wind becomes stronger, the stopper 36 prevents the valve portion 12a from rising, so that the valve portion 12a does not turn up and enter the ventilation passage W.

尚、従来のように外装材と下地との間にある通気穴に対して、通気穴とほぼ同じ位置に開閉弁がある構成においては、強風が下地に当たって跳ね返り、開閉弁を開放させる方向に圧力が生じることがある。すると、開閉弁が強風にもかかわらず閉じないこともあり得る。これを解決するため本実施形態では、水切片１１の下端内部の開閉弁１２を通気通路Ｗ側に持ち出すことで、風を受けやすくする構成とした。これにより、開閉弁１２が風を受けて円滑に閉じることができる。また、開閉弁１２の先端を下方に傾斜させて持ち出すことが排水の都合上好ましい。 In the conventional configuration where the on / off valve is located at the same position as the vent hole, the pressure is in the direction that the strong wind bounces off the base and opens the on / off valve. May occur. Then, the on-off valve may not close despite the strong wind. In order to solve this, in this embodiment, it was set as the structure which makes it easy to receive a wind by taking out the on-off valve 12 inside the lower end of the water piece 11 to the ventilation passage W side. Thereby, the on-off valve 12 can receive air and can be closed smoothly. Moreover, it is preferable for the convenience of drainage to take the tip of the on-off valve 12 inclining downward.

また、本実施形態のように、通気通路Ｗを弁部１２ａと弁受部２３とがある位置で閉鎖しうる。このため、雨水の侵入する位置を通気通路Ｗの入り口に設けることができることとなる。すると、通気孔２２と通気通路Ｗの入り口との距離を多く取ることができるため、雨水が通気通路Ｗから入って通気孔２２にまで到達する可能性を低くすることができる。この結果、雨水の通気孔２２への侵入を更に防止することができる。 Further, as in the present embodiment, the ventilation passage W can be closed at a position where the valve portion 12a and the valve receiving portion 23 are located. For this reason, the position where rainwater enters can be provided at the entrance of the ventilation passage W. Then, since the distance between the vent hole 22 and the entrance of the vent path W can be increased, the possibility that rainwater enters from the vent path W and reaches the vent hole 22 can be reduced. As a result, it is possible to further prevent rainwater from entering the ventilation hole 22.

通気水切が設置される位置は屋上へ用いることもあり、漏水リスクが非常に高い部位である。本実施形態においては、水切カバー１０によって水を切り、開閉弁１２によって止水を行い、防水層７ｂの存在によって水を返し、重力によって水をそぐというように技術的な工夫をこらした。本実施形態では、これら雨仕舞の基本要素が渾然一体となるディテールを構築した。 The location where the ventilation drainage is installed is a part where the risk of water leakage is extremely high because it may be used on the rooftop. In the present embodiment, technical ideas have been devised, such as draining water by the drain cover 10, stopping water by the on-off valve 12, returning water by the presence of the waterproof layer 7 b, and pouring water by gravity. In the present embodiment, a detail is constructed in which these basic elements of rain performance are united.

上述のように、水切カバーと取付基材はブラケットを介して係止して取り付ける構成であるため、組立が容易となり、かつ必ずしも水切カバーに通気孔を開ける作業を要さないので製作が容易となる。また、風雨が強い場合において通気通路を閉鎖し得る開閉弁は、取り外しし得る水切カバーに設置する構成であるため、開閉弁の交換が容易になし得る。 As described above, the drainage cover and the mounting base are configured to be locked and attached via a bracket, so that the assembly is easy, and the manufacture of the drainage cover is not necessarily required because the operation of opening the vent hole is not necessarily required. Become. In addition, since the on-off valve that can close the ventilation passage when wind and rain are strong is configured to be installed on a drainage cover that can be removed, the on-off valve can be easily replaced.
