【発明の属する技術分野】
本発明は、壁体の下部に配置されて水切りを行うとともに壁体内に通気を行う壁体内通気用水切り材に関する。
【0002】
【従来の技術】
住宅の壁体の下部に配置されて水切りを行う水切り材において、該水切り材を介して壁体内に空気を通気させるものとして、水切り材に単純に通気孔が上下方向に形成された構造のものがある(特開平4−222734号公報)。
【0003】
【発明が解決しようとする課題】
上記構成の水切り材においては、特に風雨が強い場合に、通気孔から雨が壁体内部に吹き込んでしまうという問題があった。
したがって、本発明の目的は、風雨が強い場合においても通気孔から雨が壁体内部に吹き込んでしまうことを防止できる壁体内通気用水切り材を提供することである。
【0004】
【課題を解決するための手段】
上記目的を達成するため、本発明の請求項1記載の壁体内通気用水切り材は、壁体の下部に配置されて水切りを行うとともに壁体内に通気を行う通気孔が形成されたものであって、第一部材と、第二部材とが外側に向けて開口した断面コ字状に組み合わされ、前記第一部材は、布基礎の上面に配置される第一平板部と、前記第一平板部から上方に延出し土台の外面の外側に配置される第二平板部とを有し、前記第二部材は、前記壁体の下面に配置され前記通気孔が形成された平板基部と、前記通気孔の前記壁体における外壁面側であって、前記第一部材の前記第一平板部の外壁面側端部よりも内側に、前記第一部材の前記第二平板部に平行に延在する第一平板部と、該第一平板部の突出先端位置に可撓性の柔軟部を介して揺動自在に設けられた弁体とを有し、前記通気孔の壁体における外壁面に対し反対側には、前記弁体が前記通気孔側に揺動した際に該弁体に当接して該弁体とによって前記通気孔を閉じる弁座部が設けられていることを特徴としている。
これにより、風雨が強くなると、通気孔の壁体における外壁面側に揺動自在に設けられた弁体が風雨で揺動させられ、通気孔の壁体における外壁面に対し反対側に設けられた弁座部に当接して通気孔を閉じ、通気孔を介しての風雨の侵入を防止する。
【0005】
本発明の請求項2記載の壁体内通気用水切り材は、請求項1記載のものに関し、前記弁体は該弁体を除く本体側に、間に柔軟部を介在させた状態で該柔軟部とともに一体成形されていることを特徴としている。
これにより、成形時に弁体および弁体を揺動自在とする柔軟部を本体側と一体成形できるため、製作が容易となる。
【0006】
本発明の請求項3記載の壁体内通気用水切り材は、壁体の下部に配置されて水切りを行うとともに壁体内に通気を行うものであって、下側仕切部と該下側仕切部の上側に中空部を介して配置された上側仕切部とを有し、前記下側仕切部および前記上側仕切部には、それぞれ通気孔が形成されており、前記下側仕切部の通気孔および前記上側仕切部の通気孔は、互いに全く重なりを生じないよう前後方向および左右方向に位置をずらしていることを特徴としている。
これにより、間に中空部を介在させつつ通気孔を有する下側仕切部と通気孔を有する上側仕切部とを設けて二重構造とし、しかも下側仕切部の通気孔と上側仕切部の通気孔とを横方向に位置をずらして配置しているため、下側仕切部の通気孔から侵入しようとする風雨が上側仕切部の通気孔を通過して壁体内に至るまでの流路が複雑となって、その侵入が防止される。
加えて、下側仕切部の通気孔から侵入する雨水の量が増加してくると中空部に雨水が充満し、該雨水の重量が風圧と均衡状態となり、雨も風も壁体内に侵入しなくなる。
【0007】
本発明の請求項4記載の壁体内通気用水切り材は、請求項3記載のものに関し、前記上側仕切部には、その通気孔より前記下側仕切部の通気孔側に、下方に突出する突出板部が形成されていることを特徴としている。
このように上側仕切部に、その通気孔より下側仕切部の通気孔側に、下方に突出する突出板部が形成されているため、下側仕切部の通気孔から侵入しようとする風雨が上側仕切部の通気孔を通過して壁体内に至るまでの流路がさらに複雑となって、その侵入がさらに防止される。
【0008】
【発明の実施の形態】
本発明の壁体内通気用水切り材の第1の実施の形態を図1および図2を参照して以下に説明する。
図中符号11は布基礎を、符号12は土台を、符号13はこの実施の形態の壁体内通気用水切り材を、符号14は壁体を、それぞれ示している。
土台12は、その鉛直延在する外面12aが布基礎11の鉛直延在する外面11aから若干建物内側(図1における右側)にずらされた状態で布基礎11の上面11b上に設置されている。
【0009】
壁体内通気用水切り材13は、壁体14の下部に配置されて水切りを行うもので、第一部材16および第二部材17の二つが組み合わされて構成されている。第一部材16は、布基礎11の上面11b上に配置される第一平板部19と、該第一平板部19の一側から垂直方向に突出して布基礎11の外面11aに係止される係止部20と、第一平板部19の係止部20に対し反対側から係止部20に対し裏方向に延出して土台12の外面12aの外側に配置される第二平板部21と、該第二平板部21の第一平板部19に対し反対側であって土台12に対し反対側に設けられた、第二部材17を接合するための接合凹部形成部22とを有している。
【0010】
第二部材17は、平板基部24と、平板基部24の一側に設けられて該平板基部24を第一部材16の第一平板部19に対し平行させた状態で上記接合凹部形成部22に接合される接合凸部25と、接合された第一部材16の第一平板部19側に平板基部24から突出し第一部材16の第二平板部21に平行に延在する第一平板部26と、平板基部24における第一平板部26の接合凸部25に対し反対側に該第一平板部26と平行に延在して、接合された第一部材16の第一平板部19側に突出する第二平板部27と、平板基部24の第二平板部27に対し裏側に第二平板部27と同一平面をなすよう延在する第三平板部28と、平板基部24の第三平板部28と接合凸部25との間位置から第三平板部28と同側に平行に突出延在する第四平板部29とを有している。ここで、第四平板部29の高さは接合された第一部材16の第二平板部21の高さと一致されている。
【0011】
第二部材17の平板基部24の接合凸部25と、第一平板部26および第四平板部29との間位置には、壁体14内に通気を行う通気孔30が、取り付け状態において上下となる方向に貫通形成されている。
そして、この実施の形態において、第二部材17には、その第一平板部26の突出先端位置の接合凸部25側の端縁部に、平板状の弁体32が繰り返し可撓可能な軟質の柔軟部33を介して揺動自在に設けられている。なお、この弁体32は、該弁体32を除く第二部材17側に、柔軟部33とともに一体成形されている。
【0012】
取り付け状態において、弁体32は、自重により下側に延出すると第一部材16から離間して通気孔30を開放させる一方、通気孔30側に揺動すると第一部材16の係合凹部形成部22の下面側の弁座部34に当接して通気孔30を閉じる。
なお、上記により、弁体32は通気孔30の壁体14における外壁面14a側(図1における左側)に揺動自在に設けられ、弁座部34は通気孔30の壁体14における外壁面14aに対し反対側(図1における右側)に設けられることになる。
【0013】
壁体14は、壁体内通気用水切り材13の第一部材16の第二平板部21および第二部材17の第四平板部29上に配置される下地桟木36と、この下地桟木36と第二部材17の第三平板部28との間に配置されるモルタル下地板37と、モルタル下地板37の外側すなわち壁体14の最も外側に施行されるモルタル38とで構成されている。
【0014】
上記壁体内通気用水切り材13の周囲の施行手順は、まず、布基礎11が施行完成すると、布基礎11に土台12および図示せぬ柱を設置し、次に、下地桟木36を土台12の外面12aに固定する。そして、下地桟木36の外面36aにモルタル下地板37を固定した後、下地桟木36およびモルタル下地板37と布基礎11との間に壁体内通気用水切り材13を挿入しつつこれを固定し、モルタル下地板37の外側をモルタル38で仕上げる。
【0015】
以上に述べた第1の実施の形態によれば、風雨が強くなると、風雨の力で、通気孔30の壁体14における外壁面14a側に揺動自在に設けられた弁体32が柔軟部33が撓むことで揺動させられ、通気孔30の壁体14における外壁面14aに対し反対側に設けられた弁座部34に当接して通気孔30を閉じ、通気孔30を介しての風雨の侵入を防止する。
したがって、風雨が強い場合においても通気孔30から雨が壁体14の内部に吹き込んでしまうことを防止できる。
勿論、風雨がない場合は、弁体32が自重で弁座部34から離間し通気孔30を開放させて壁体14の内部の通気を良好に行わせることになる。
なお、弁体32は、該弁体32を除く第二部材17側に柔軟部33とともに一体成形されているため、製作が容易となる。
【0016】
次に、本発明の壁体内通気用水切り材の第2の実施の形態を図3および図4を参照して第1の実施の形態との相違部分を中心に以下に説明する。なお、第1の実施の形態と同様の部分には同一の符号を付しその説明を略す。
【0017】
第2の実施の形態の壁体内通気用水切り材40も、第一部材41および第二部材42の二つが組み合わされて構成されている。
第一部材41は、布基礎11の上面11b上に配置される第一平板部44と、該第一平板部44の一側から垂直方向に突出して布基礎11の外面11aに係止される係止部45と、第一平板部44の係止部45に対し反対側から係止部45に対し裏方向に延出して土台12の外面12aの外側に配置される第二平板部46と、該第二平板部46の第一平板部44に対し反対側から第一平板部44と平行をなして延在する平板基部(下側仕切部)47とを有している。
【0018】
加えて、第一部材41は、平板基部47の第二平板部46に対し裏側に突出形成された、第二部材42を接合するための接合凸部48と、第一平板部44側に平板基部47から突出し第二平板部46に平行に延在する第三平板部49と、平板基部47における第三平板部49の第二平板部46に対し反対側に該第三平板部49と平行に延在して第一平板部44側に突出する第四平板部50と、平板基部47の第四平板部50に対し裏側に第四平板部50と同一平面をなすよう延在する第五平板部51と、平板基部47の第五平板部51と接合凸部48との間位置にこれらと同側に第五平板部51と平行に突出延在する第六平板部52とを有している。
【0019】
第二部材42は、平板基部(上側仕切部)54と、平板基部54の一側から該平板基部54に垂直に突出形成されることにより、該平板基部54を第一部材41の平板基部47に対し平行させるようにして上記接合凸部48に接合される接合凹部形成部55と、平板基部54の他側から接合凹部形成部55と平行かつ同高さに延在形成された第一平板部56と、平板基部54における第一平板部56と接合凹部形成部55との間にこれらと同側にこれらと平行かつこれらより低く突出形成された第二平板部(突出板部)57とを有している。
【0020】
そして、接合凸部48と接合凹部形成部55との接合によりこれら第一部材41および第二部材42を接合させると、第一部材41の平板基部47と第二部材42の平板基部54とが平行をなすとともに、第一部材41の第六平板部52の内側に第二部材42の第一平板部56が配置されることになり、第一部材41の平板基部47と、第二部材42の接合凹部形成部55、平板基部54および第一平板部56とで、中空部59が画成されることになる。
【0021】
そして、この実施の形態においては、第一部材41の平板基部47には中空部59を外部に連通させる通気孔60が形成されており、第二部材42の平板基部54にも中空部59を外部に連通させる通気孔61が形成されている。これらの通気孔60,61は、互いに横方向に、全く重なりを生じないよう位置をずらしており、具体的には、図4に示すように前後方向および左右方向の両方向に位置をずらしている。ここで、第一部材41の通気孔60は第二部材42の通気孔61より壁体14における外壁面14a側に配置されている。
加えて、第二部材42の第二平板部57は、横方向において通気孔61より通気孔60側の位置であって該通気孔60に若干重なる位置から下方に突出している。
【0022】
以上に述べた第2の実施の形態によれば、間に中空部59を介在させつつ通気孔60を有する下側の平板基部47と通気孔61を有する上側の平板基部54とを設けて二重構造とし、しかも下側の平板基部47の通気孔60と上側の平板基部54の通気孔61とを横方向に位置をずらして配置しているため、下側の平板基部47の通気孔60から侵入しようとする風雨が上側の平板基部54の通気孔61を通過して壁体14の内部に至るまでの流路が複雑となって、その侵入が防止される。
加えて、下側の平板基部47の通気孔60から侵入する雨水の量が増加してくると中空部59に雨水が充満し、該雨水の重量が風圧と均衡状態となり、雨も風も壁体14の内部に侵入しなくなる。
したがって、風雨が強い場合において通気孔60,61から雨が壁体14の内部に吹き込んでしまうことを防止できる。
【0023】
しかも、上側の平板基部54には、その通気孔61より通気孔60側に、下方に突出する第二平板部57が形成されているため、下側の平板基部47の通気孔60から侵入しようとする風雨が上側の平板基部54の通気孔61を通過して壁体14の内部に至るまでの流路がさらに複雑となって、その侵入がさらに防止される。
したがって、風雨が強い場合においても通気孔60,61から雨が壁体14の内部に吹き込んでしまうことを確実に防止できる。
【0024】
【発明の効果】
以上詳述したように、本発明の請求項1記載の壁体内通気用水切り材によれば、風雨が強くなると、通気孔の壁体における外壁面側に揺動自在に設けられた弁体が風雨で揺動させられ、通気孔の壁体における外壁面に対し反対側に設けられた弁座部に当接して通気孔を閉じ、該通気孔を介しての風雨の侵入を防止する。
したがって、風雨が強い場合においても通気孔から雨が壁体内部に吹き込んでしまうことを防止できる。
【0025】
本発明の請求項2記載の壁体内通気用水切り材によれば、成形時に弁体および弁体を揺動自在とする柔軟部を本体側と一体成形できるため、製作が容易となる。
【0026】
本発明の請求項3記載の壁体内通気用水切り材によれば、間に中空部を介在させつつ通気孔を有する下側仕切部と通気孔を有する上側仕切部とを設けて二重構造とし、しかも下側仕切部の通気孔と上側仕切部の通気孔とを横方向に位置をずらして配置しているため、下側仕切部の通気孔から侵入しようとする風雨が上側仕切部の通気孔を通過して壁体内に至るまでの流路が複雑となって、その侵入が防止される。
加えて、下側仕切部の通気孔から侵入する雨水の量が増加してくると中空部に雨水が充満し、該雨水の重量が風圧と均衡状態となり、雨も風も壁体内に侵入しなくなる。
したがって、風雨が強い場合においても通気孔から雨が壁体内部に吹き込んでしまうことを防止できる。
【0027】
本発明の請求項4記載の壁体内通気用水切り材によれば、上側仕切部に、その通気孔より下側仕切部の通気孔側に、下方に突出する突出板部が形成されているため、下側仕切部の通気孔から侵入しようとする風雨が上側仕切部の通気孔を通過して壁体内に至るまでの流路がさらに複雑となって、その侵入がさらに防止される。
したがって、風雨が強い場合においても通気孔から雨が壁体内部に吹き込んでしまうことを確実に防止できる。
