Description

【０００１】
【発明の属する技術分野】
本発明は屋根やバルコニーの床や外壁等の防水構造に関し、特にバルコニーの床に好適な防水構造に関する。
【０００２】
【従来の技術】
従来、屋根やバルコニーの床や外壁等の防水構造としては種々知られている。例えば、実公昭５５−１３５２１号公報や特開平１０−１１４９９７号公報には、バルコニー床梁の上に防水材（上記公報では床水切り板や不透水性床材と記載されている）を取り付けたバルコニー床の防水構造が記載されている。
又、特開平９−２０９５１２号公報や特許第２９８７７４６号には、屋根、バルコニー、外壁等の直線状の溝が形成された下地材の表面を防水する防水構造が記載されている。
【０００３】
即ち、特開平９−２０９５１２号公報の防水構造は、溝の深さとほぼ同じ深さに窪んだ断面コ字形の窪みと、この窪みの両側に設けられた平板状の鍔とからなる長尺体の溝部取付材と、この溝部取付材の窪みの中に挿入可能で、中央部に係合凹部を有する長尺体の保持材と、平板状の防水材と、下面に嵌合凸部が設けられた長尺体の結合部とからなり、溝部取付材が、窪みを溝の中に挿入し、鍔を溝の周縁部の下地材に載せた状態に、取り付けられ、保持材が、溝部取付材の窪みの中に挿入され、防水材が、端面を保持材の係合凹部の上方で対峙させ、この対峙する端面間に若干隙間を設けた状態に、取り付けられ、結合材が、両側を防水材の側縁部に重ね、係合凸部を防水材の対峙している端面の間から窪みの中に挿入し、この嵌合凸部を保持材の係合凹部に嵌合させた状態に、取り付けられている構造をしている。
【０００４】
又、特許第２９８７７４６号の防水構造は、下地材を覆う防水材には、一側縁部に、溝の内側に沿う形状の断面コ字形の窪みと、この窪みの先端側に設けられた平板状の鍔と、この窪みの中に窪みの深さとほぼ同じ長さに立上された立ち上がり部と、この立ち上がり部の先端に設けられたほぼ水平な水平部とからなる板端受け部とが設けられ、他側縁部に、先端から下方にほぼ直角に折曲した状態に延設されたＶ字状部と、前記板端受け部に引っ掛け可能な引掛部とが設けられていて、防水材が、窪みを溝部の中に挿入した状態に取り付けられ、隣の防水材が、既に取り付けられている防水材の窪みの中に設けられている板端受け部に、引掛部を引っ掛けた状態に、取り付けられている構造をしている。
【０００５】
【発明が解決しようとする課題】
しかし、実公昭５５−１３５２１号公報や特開平１０−１１４９９７号公報に記載されているバルコニーの床の防水構造は、床面積が比較的小さく、１枚の防水材を取り付けるだけで、バルコニーの床を防水構造にする場合には極めて好適であるが、バルコニーの床面積が大きくなると、複数の防水材を接続する必要があり、この防水材の接続部分から雨水が漏れるという問題がある。
【０００６】
そこで、この防水材の重ねられている接続部分を防水するために、この重合された防水材の間にシール材を設けて防水しようとしたが、長年月使用している間にシール材が劣化することと、防水材が夏冬の温度差によって膨張収縮を繰り返すこととで、このシール材に亀裂が入り、重合されている防水材の間から雨水が漏れ出すことが判明した。
【０００７】
又、特開平９−２０９５１２号公報や特許第２９８７７４６号に記載されている防水構造は、下地材に溝を設け、この溝の中に樋とほぼ同じ作用をする窪みのある長尺体を設けていて、防水材の上に降った雨水を窪みの中に流れ込むようにしているので、防水材が膨張収縮しても、雨水が漏れず好ましい構造である。
【０００８】
しかし、上記特開平９−２０９５１２号公報に記載されている防水構造では、溝部取付材と保持材と防水材と結合部とからなるように、多くの部材が必要であり、しかも、この部材が、例えば、係合凸部や嵌合凹部を設けるというように、複雑な形状をしていて、製造が困難である。又、この防水構造は屋根や外壁等のように人が殆ど載らない場所を防水する防水構造としては好適であるが、この防水構造をバルコニーの床のように人が度々載る床に適用すると、溝の上方の結合材の上に人が載ったときに、結合材の嵌合凸部が保持材の係合凹部の中を上下に移動し不安定であり、更に、重い人が載ったり、上下に度々移動していると、下方に移動した結合材が元の形状に戻らなくなり、この部分に窪みが生じ、水溜まりが発生するという問題がある。
【０００９】
又、特許第２９８７７４６号に記載されている防水構造では、防水材の一側縁部に、窪みと鍔と立ち上がり部と板端受け部とを設け、他側縁部に、Ｖ字状部と引掛部とを設けるというように、複雑な形状の防水材を必要とし、製造し難く不便であると同時に、この防水材は複雑な形状をしていて嵩張るので、防水材の運搬に多くのスペースが必要であり、運搬費用が高くなるという問題がある。又、この防水構造をバルコニーの床に適用すると、防水材と隣の防水材のＶ字状部と間に隙間が形成されるので、この上に人工芝等を敷いても、この部分が窪み醜悪となる。
【００１０】
そこで、本発明の目的は、防水材が膨張収縮しても雨水の漏れない溝が形成された下地材を防水する防水構造であって、部材数が少なく、部材や防水材を複雑な形状にする必要がなく、しかも、溝の上方に人が載っても窪まない防水構造を提供することである。
【００１１】
【課題を解決するための手段】
本発明は上記目的を達成するためになしたものであって、請求項１記載の発明は、直線状の溝が形成された下地材の表面を防水する防水構造であって、前記溝の深さとほぼ同じ深さに窪んだ窪みと、この窪みの両側に設けられた平板状の鍔とからなる長尺体の溝部取付材と、平板状の防水材と、平らな上面と、下面のほぼ中央に溝部取付材の窪みの深さとほぼ同じ長さに下方に突出した突出部とを有する長尺体のカバー材とからなり、前記溝部取付材が、窪みを下地材の溝の中に挿入し、鍔を溝の周縁部の下地材に載せた状態に、取り付けられ、前記防水材が、側縁部を窪みの縁から窪みの中に突出させた状態に、下地材と溝部取付材の鍔の上に、取り付けられ、前記カバー材が、突出部を窪みの中に挿入し、両側縁部を防水材の側縁部の上に載せた状態に、取り付けられているものである。
【００１２】
請求項２記載の発明は、直線状の溝が形成された下地材の表面を防水する防水構造であって、前記溝の深さとほぼ同じ深さに窪んだ窪みと、この窪みの両側に設けられた平板状の鍔と、この窪みのほぼ中央に窪みの深さとほぼ同じ高さに上方に突出した突出部とからなる長尺体の溝部取付材と、平板状の防水材と、平板状長尺体のカバー材とからなり、前記溝部取付材が、窪みを下地材の溝の中に挿入し、鍔を溝の周縁部の下地材に載せた状態に、取り付けられ、前記防水材が、側縁部を窪みの縁から窪みの中に突出させた状態に、下地材と溝部取付材の鍔の上に、取り付けられ、前記カバー材が、中央部を溝部取付材の突出部に載せ、両側縁部を防水材の側縁部の上に載せた状態に、取り付けられているものである。
【００１３】
さらに、本発明は、上記した発明に係り、前記溝部取付材の鍔と前記防水材の側縁部との間と、前記防水材の側縁部と前記カバー材の間とにシール材が設けられているものである。
【００１４】
（作用）
請求項１記載の発明では、防水材が、側縁部を窪みの縁から窪みの中に突出させた状態にして、下地材と溝部取付材の鍔の上に、取り付けられているので、防水材の上に降った雨水は、窪みの中に突出している防水材の先端から溝部取付材の窪みの中に落下する。
しかも、この防水材の側縁部は窪みの中に突出しているので、防水材が熱膨張収縮しても、この窪みの中に突出している長さが長くなったり、短くなるだけである。従って、長年月使用しても防水効果が低下しない。
【００１５】
又、請求項１記載の発明に使用する溝部取付材は、溝の深さとほぼ同じ深さに窪んだ窪みと、この窪みの両側に設けられた平板状の鍔とからなる。
そして、この請求項１記載の発明では、この溝部取付材が、窪みを下地材の溝の中に挿入し、鍔を溝の周縁部の下地材に載せた状態に、取り付けられている。
従って、この取り付けられた溝部取付材は、窪みの下面が溝の底面に沿い、鍔が溝の周縁部の下地材の表面に沿った状態になっていて、上方から溝部取付材に力が加わっても窪みや鍔が下方に移動しないようになっている。
【００１６】
又、請求項１記載に使用するカバー材は、平らな上面と、下面のほぼ中央に溝取付材の窪みの深さとほぼ同じ長さに下方に突出した突出部とを有する。
そして、この請求項１記載の発明では、このカバー材が、突出部を窪みの中に挿入し、両側縁部を防水材の側縁部の上に載せた状態に、取り付けられている。このようになっているので、カバー材は、両側縁部が、下地材に下方に移動しないように載っている鍔とその上の防水材の上に載せられて支持され、中央部の突出部が、下方に移動しないように取り付けられている溝部取付材の底面に載せられて支持されていて、溝の上方のカバー材の上に人が載っても窪まないようになっている。
【００１７】
又、カバー材の上面は平らであり、しかも、カバー材の両側縁部が防水材の側縁部の上に載っていて、平板状の防水材と、カバー材の上面とは、カバー材の厚みだけの凹凸があるがこの凹凸は小さく、床面全体がほぼ平らな面となっていて歩き易い。
このように、この請求項１記載の防水構造は、溝の上に人が載っても窪まないし、床面が平らで歩き易くバルコニーの床に好適な防水構造である。
又、この請求項１記載の防水構造に使用する部材は、溝部取付材、防水材、カバー材というように、特開平９−２０９５１２号公報に記載されている防水構造に使用する部材より数が少なく、しかも、この使用する部材が簡単な構造をしていて製造し易く便利であるし、防水材は平板状で運搬し易い。
【００１８】
請求項２記載の発明では、防水材が、側縁部を窪みの縁から窪みの中に突出させた状態にして、下地材と溝部取付材の鍔の上に、取り付けられているので、防水材の上に降った雨水は窪みの中に突出している先端から溝部取付材の窪みの中に落下する。
しかも、この防水材の側縁部は窪みの中にほぼ水平に突出しているので、防水材が熱膨張収縮しても、この窪みの中に突出している長さが長くなったり、短くなるだけである。従って、長年月使用しても防水効果が低下しない。
【００１９】
又、請求項２記載の発明に使用する溝部取付材は、溝の深さとほぼ同じ深さに窪んだ窪みと、この窪みの両側に設けられた平板状の鍔と、この窪みのほぼ中央に窪みの深さとほぼ同じ高さに上方に突出した突出部とからなる。
そして、請求項２記載の発明では、この溝部取付材が、窪みを下地材の溝の中に挿入し、鍔を溝の周縁部の下地材に載せた状態に、取り付けられている。
従って、この取り付けられた溝部取付材は、窪みの下面が溝の底面に沿い、鍔が溝の周縁部の下地材の表面に沿った状態になっていて、上方から溝部取付材の鍔部、窪みの底面や、窪みから突出している突出部に力が加わっても移動しないようになっているし、突出部は鍔とほぼ同じ高さになっている。
【００２０】
請求項２記載の発明に使用するカバー材は平板状長尺体である。
そして、請求項２記載の発明では、このカバー材が、中央部を溝取付部材の突出部に載せ、両側縁部を防水材の側縁部の上に載せた状態に、取り付けられている。
このようになっているので、カバー材は、両側縁部が、下地材に下方に移動しないように載っている鍔とその上の防水材の側縁部に支持され、中央部が、溝取付部材の鍔とほぼ同じ高さに突出していて、下方に移動しない突出部に支持されていて、下地材の溝の上方のカバー材の上に人が載っても窪まないようになっている。尚、防水材の両側縁部と中央部との高さは防水材の厚みだけ異なるが、この差は小さく問題にならない。
【００２１】
又、カバー材の上面は平らであり、しかも、カバー材の両側縁部を防水材の側縁部の上に載っていて、平板状の防水材と、カバー材の上面とは、カバー材の厚みだけの凹凸があってもこの凹凸はきわめて小さく、床面全体がほぼ平らな面となっていて歩き易い。
このように、この請求項２記載の防水構造は、溝部の上に人が載っても窪まないし、床面が平らで歩き易いバルコニーの床に好適な防水構造である。
又、この請求項２記載の防水構造に使用する部材は、溝部取付材、防水材、カバー材というように、特開平９−２０９５１２号公報に記載されている防水構造に使用する部材より数が少なく、しかも、この使用する部材が簡単な構造をしていて製造し易く便利であるし、防水材は平板状で運搬し易い。
【００２２】
さらに、本発明では、上記した発明に係り、前記溝部取付材の鍔と前記防水材の側縁部との間と、前記防水材の側縁部と前記カバー材の間とにシール材が設けられているので、この溝部取付材の鍔と防水材の側縁部との間と、防水材の側縁部とカバー材の間の防水性能が更に向上するし、防水材が移動しなくなる。
【００２３】
しかも、長年月使用している間にシール材が劣化してこのシール材に亀裂が生じても、この亀裂を通して浸入する雨水は溝部取付材の窪みの中に落下するので下地材まで漏れることがないし、この亀裂から浸入する雨水は少なく、従って、大雨のときでも、溝部取付材の窪みの中の雨水が溢れるということがない。
【００２４】
【発明の実施の形態】
次に、本発明の実施の形態を実施例で説明する。
（実施例１）
図１〜図６は本発明をユニット建物に採用した一実施例を示すもので、図１はユニット建物を示す斜視図、図２は建物ユニットを示す一部切欠斜視図、図３は図１のＡ−Ａ線における断面図、図４はバルコニー床の溝部分を構成部材に分解した状態を示す断面図、図５は溝部取付材の斜視図、図６はカバー材の斜視図である。
【００２５】
図１〜図６において、Ｕはユニット建物であり、このユニット建物Ｕは、図１に示すように、基礎９９の上に９個の建物ユニット１が据え付けられて１階が形成され、この１階の建物ユニット１の上に９個の建物ユニット１が据え付けられて２階が形成され、この２階の建物ユニット１の上に屋根パネル２が取り付けられ、２階の開口部３の屋外側にバルコニー４が取り付けられたものである。
【００２６】
このとき使用する建物ユニット１は、図２に示すように、矩形の四隅に立設された４本の鋼製の四角筒体の柱１１と、この４本の柱１１の下端部を矩形の辺に沿って連結した４本の鋼製の断面コ字形長尺体の床梁１２と、この４本の柱１１の上端部を矩形の辺に沿って連結した４本の鋼製の断面コ字形長尺体の天井梁１３とからなる骨格を備えている。
【００２７】
そして、この建物ユニット１は、この骨格の対向する長辺の床梁１２、１２に複数本の鋼製の四角筒体の床小梁１５がほぼ平行に差し渡されて取り付けられ、この床小梁１５の上に木製の床根太１６が取り付けられ、この上にパーチクルボードの床材１４が取り付けられて床が形成され、対向する長辺の天井梁１３、１３に複数本の木製の天井野縁１７がほぼ平行に差し渡されて取り付けられ、この天井野縁１７の下面に石膏ボードの天井材１８が取り付けられて天井が形成され、外壁を設ける場所には、床梁１２と天井梁１３との間に間柱１９が取り付けられ、この間柱１９の屋外側と屋内側に外壁パネルと、内壁パネルとが取り付けられ、この外壁パネルと内壁パネルの間にガラスウールの断熱材が設けられて壁が形成されたものである。
【００２８】
開口部３には、窓３１が取り付けられていて、この窓３１を開いて、バルコニー４に出入可能になっている。
バルコニー４は、図３に示すように、ほぼ矩形状に組み立てられた鋼製の断面コ字形長尺体のバルコニー床梁４１と、この対向するバルコニー床梁４１に複数本の鋼製の四角筒体のバルコニー床小梁４２が屋外方向に傾斜した状態に差し渡されて取り付けられ、このバルコニー床小梁４２の上に木製の床根太４３が取り付けられ、この床根太４３の上にバルコニー床４４が設けられ、屋外側のバルコニー床梁４１に手摺り４５が取り付けられ、バルコニー床小梁４２の屋外側には樋４６が取り付けられたものである。又、バルコニー床４４の下方には軒天井４８が設けられている。
【００２９】
そして、このバルコニー４は、図１に示すように、屋内側が開口部３の屋外側に取り付けられ、屋外側が支柱４９に支持されていて、この支柱４９に沿って縦樋４７が取り付けられ、この縦樋の先端は前記樋４６に接続されている。
バルコニー床４４は、図４に示すように、床根太４３の上に取り付けられた下地材５と溝部取付材６と防水材７とカバー材８と床仕上げ材９とからなる。
【００３０】
下地材５は、床根太４３の上に取り付けられた合板の下側下地材５１と、この下側下地材５１の上に、ほぼ中央に隙間を設けて取り付けられた合板の上側下地材５２と、この上側下地材５２の隙間に形成された溝５３とからなる。
溝部取付材６は、塩化ビニル樹脂被覆鋼板であり、図５に示すように、窪み６１と鍔６２と壁取付部６３と水切り６４とからなる。
【００３１】
窪み６１は、下地材５の溝５３の中に挿入可能で、この溝５３の深さとほぼ同じ深さに窪んだ断面コ字形をしている。又、鍔６２は平板状をしていて、この窪み６１の両側に設けられている。そして、この窪み６１と鍔６２とは塩化ビニル樹脂被覆鋼板をΩ形に折曲して製造した断面Ω形長尺体であり、この長尺体の長さは下地材５の屋外側から屋内側までとほぼ等しい。
【００３２】
壁取付部６３は、窪み６１と鍔６２とからなる長尺体の屋内側に立設され、溶接で長尺体に取り付けられている。
水切り６４は、窪み６１から延設されたものであり、窪み６１の屋外側から垂れ下げられている。
防水材７は、平板状の塩化ビニル樹脂被覆鋼板である。
【００３３】
カバー材８は、図６に示すように、本体８１と壁取付部８２とからなる。
本体８１は、図４、図６に示すように、塩化ビニル樹脂被覆金属板を折曲して製造したものであって、下面のほぼ中央に溝部取付材６の窪み６１とほぼ同じ高さに下方断面コ字形に突出した突出部８１１と、平らな上面８１２とを有する下地材５の屋外側から屋内側までとほぼ等しい長さの長尺体である。
【００３４】
壁取付部８２は本体８１の屋内側に立設され、溶接で本体８１に取り付けられている。
床仕上げ材９は合成樹脂製の人工芝である。
９５はシール材である。
屋根パネル２は従来とほぼ同じであるので説明を省略する。
【００３５】
次に、このユニット建物の施工方法について説明する。
図２に示すように、工場で、矩形の四隅に４本の柱１１を立設し、この４本の柱１１の下端部を４本の床梁１２で連結し、４本の柱１１の上端部を４本の天井梁１３で連結して建物ユニット１の骨格を製造する。
【００３６】
そして、この建物ユニット１の骨格の対向する長辺の床梁１２、１２に複数本の床小梁１５をほぼ平行に差し渡して取り付け、この床小梁１５の上に床根太１６を取り付け、この上に床材１４を取り付けて床を形成し、対向する長辺の天井梁１３、１３に複数本の天井野縁１７をほぼ平行に差し渡して取り付け、この天井野縁１７の下面に天井材１８を取り付けて天井を形成し、外壁を設ける場所には、床梁１２と天井梁１３との間に間柱１９を取り付け、この間柱１９の屋外側と屋内側に外壁パネルと、内壁パネルを取り付け、この外壁パネルと内壁パネルの間にガラスウールの断熱材を設けて壁を形成し、種々な仕上げを行うと建物ユニット１が完成する。
【００３７】
尚、この際、バルコニー４を取り付ける建物ユニット１には開口部３を設け、この開口部３に窓３１を取り付ける。
又、屋根パネル２を製造する。
又、バルコニー床梁４１をほぼ矩形状に組み立て、この対向するバルコニー床梁４１にバルコニー床小梁４２を屋外方向に傾斜した状態に差し渡して取り付け、このバルコニー床小梁４２の上に床根太４３を取り付け、この床根太４３の上にバルコニー床４４を取り付け、屋外側のバルコニー床梁４１に手摺り４５を取り付け、バルコニー床小梁４２の屋外側に樋４６を取り付けてバルコニー４を製造する。
【００３８】
この際のバルコニー床４４の施工方法について説明する。
図４に示すように、床根太４３の上に下側下地材５１を取り付け、この下側下地材５１の上に、ほぼ中央に隙間を設けて上側下地材５２を取り付けて、この隙間に溝５３を形成した状態に、下地材５を設ける。
一方、塩化ビニル被覆鋼板を、図５に示すように、断面コ字形に折り曲げて窪み６１と鍔６２とからなる長尺体とし、窪み６１の屋外側先端を下方に折り曲げて水切り６４を形成し、屋内側端部に壁取付部６３を溶接して取り付けて溝部取付材６を製造する。
【００３９】
又、塩化ビニル樹脂被覆鋼板を、図６に示すように、折り曲げて、突出部８１１と上面８１２とからなる本体８１とし、この屋内側端部に壁取付部８２を溶接して取り付けてカバー材８を製造する。
そして、壁取付部６３を屋内側に立設させ、水切り６４を屋外側に垂下させ、図４に示すように、窪み６１を下地材５の溝５３の中に挿入し、鍔６２を溝５３の周縁部の下地材５に載せて、溝部取付材６を下地材５に取り付ける。
この水切り６４の下方に軒樋４６を取り付ける。
【００４０】
次に、溝部取付材６の鍔６２の上にシール材９５を塗布し、防水材７を上側下地材５２の上に取り付ける。
この際、図４に示すように、防水材７の側縁部を、溝部取付材６の鍔６２の上を通って窪み６１の中にほぼ水平に突出させ、シール材９５の上から防水材７の側縁部を溝部取付材６の鍔６２に押し付けて防水材７を溝部取付材６に接着する。
【００４１】
次に、防水材７の側縁部にシール材９５を塗布し、カバー材８を取り付ける。この際、カバー材８の突出部８１１を溝部取付材６の窪み６１の中に挿入し、突出部８１１の両側縁部をシール材９５の上から防水材７の側縁部に押し付けて、カバー材８を防水材７に接着する。
この防水材７とカバー材８の上に床仕上げ材９を敷いて、バルコニー床４４を製造する。
このようにして製造した建物ユニット１、屋根パネル２、バルコニー４を施工現場に運搬する。
【００４２】
施工現場では、予め設けられている基礎９９の上に９個の建物ユニット１を据え付けて１階を形成し、この１階の建物ユニット１の上に９個の建物ユニット１を据え付けて２階を形成し、この２階の建物ユニット１の上に屋根パネル２を取り付ける。
又、１階の天井梁１３に屋内側のバルコニー床４１を取り付け、屋外側に支柱４９を立設し、この支柱に屋外側のバルコニー床４１を取り付けて、２階の開口部３の屋外側にバルコニー４を取り付ける。
【００４３】
すると、壁取付部６３、８２が壁面に沿うので、この部分にシール材を取り付けてシールする。
更に、バルコニー床４４の防水材７と壁面との隙間をシールしたり、軒樋４６に縦樋４７を取り付けたり、種々な仕上げを行うとユニット建物Ｕが完成する。
【００４４】
このようにして完成したユニット建物Ｕでは、防水材７が、側縁部を窪み６１の縁から窪み６１の中にほぼ水平に突出させた状態にして、下地材５と溝部取付材６の鍔６２の上に、取り付けられているので、防水材７の上に降った雨水は溝部取付材６の窪み６１の中に落下し、この窪み６１の中を流れ、水切り６４から樋４６、縦樋４７を経て地上に流れ落ちる。
そして、この防水材７の側縁部は窪み６１の中にほぼ水平に突出しているので、防水材７が熱膨張収縮しても、この窪みの中に突出している長さが長くなったり、短くなるだけである。従って、長年月使用しても防水効果が低下しない。
【００４５】
又、溝部取付材６が、窪み６１を下地材５の溝５３の中に挿入し、鍔６２を溝５３の周縁部の下地材５に載せた状態に、取り付けられているので、上方から溝部取付材６に力が加わっても窪み６１や鍔６２が下方に移動しないようになっている。
そして、カバー材８は、突出部８１１を窪み６１の中に挿入し、両側縁部を防水材５の側縁部の上に載せた状態に、取り付けられているので、カバー材８は、両側縁部が防水材７の上に載せられて下方に移動しないように支持され、又、ほぼ中央に設けられている突出部８１１の先端が、下方に移動しない溝部取付材６の窪み６１の底面に当接して下方に移動しないように支持されている。
【００４６】
このようになっているので、この溝５３の上方のカバー材８の上に人が載っても窪まない。
又、カバー材８の上面はほぼ平らで、しかも、カバー材８の両側縁部が防水材５の側縁部の上に載っていて、平板状の防水材５と、カバー材８の上面とは、カバー材８の厚みだけの凹凸があるがこの凹凸はきわめて小さく、床面全体がほぼ平らな面となっていて歩き易い。特に、床仕上げ材９を敷いていると、この凹凸が隠れて床仕上げ材９の上は歩き易くなる。
【００４７】
又、このバルコニー床４４の防水構造に使用する部材は、溝部取付材６、防水材７、カバー材８というように、種類が少なく、しかも、この使用する部材が簡単な構造をしていて製造し易く便利である。
又、溝部取付材６の鍔６２と防水材７の側縁部との間と、防水材７の側縁部とカバー材８の間とにシール材９５が設けられているので、この溝部取付材６の鍔６２と防水材７の側縁部との間と、防水材５の側縁部とカバー材８の間の防水性能が更に向上するし、防水材７が移動しなくなる。
【００４８】
しかも、長年月使用している間に、シール材９５が劣化してこのシール材９５に亀裂が生じても、この亀裂を通して浸入する雨水は溝部取付材６の窪みの中に落下するので下地材５まで漏れることがないし、この亀裂から浸入する雨水は少なく、従って、大雨のときでも、溝部取付材６の窪みの中の雨水が溢れるということがない。
尚、この実施例１では、突出部８１１を１条設けているが、２条以上設けてもよい。
【００４９】
（実施例２）
図７〜図９は本発明の他の一実施例を示すもので、図７はバルコニー床の溝部分を構成部材に分解した状態を示す断面図、図８は溝部取付材の斜視図、図９はカバー材の斜視図である。
【００５０】
この図７〜図９に示す実施例２を図１〜図６に示す実施例１と比較すると、バルコニー床４４ａの構造が異なり、その他は、ほぼ同じであるので、このバルコニー床４４ａの構造について説明し、その他の構造の説明を省略する。
【００５１】
バルコニー床４４ａは、図７に示すように、床根太４３ａの上に取り付けられた下地材５ａと溝部取付材６ａと防水材７ａとカバー材８ａと床仕上げ材９ａとからなる。
下地材５ａは、床根太４３ａの上に取り付けられた合板の下側下地材５１ａと、この下側下地材５１ａの上に、ほぼ中央に隙間を設けて取り付けられた合板の上側下地材５２ａと、この上側下地材５２ａの隙間に形成された溝５３ａとからなる。
【００５２】

突出部６９ａは、窪み６１ａのほぼ中央部に、窪み６１ａとほぼ同じ高さに上方に断面コ字形に突出したものである。
【００５３】
鍔６２ａは平板状であり、この窪み６１ａの両側に設けられている。そして、この窪み６１ａと突出部６９ａと鍔６２ａとは塩化ビニル樹脂被覆鋼板を折曲して成形したもので、下地材５ａの屋外側から屋内側までとほぼ等しい長さの長尺体である。
壁取付部６３ａは、窪み６１ａと突出部６９ａと鍔６２ａとからなる長尺体の屋内側に立設され、溶接で長尺体に取り付けられている。
水切り６４ａは、窪み６１ａから延設されたもので、窪み６１ａの屋外側から垂れ下げられている。
防水材７ａは、平板状の塩化ビニル樹脂被覆鋼板である。
【００５４】
カバー材８ａは、図９に示すように、本体８１ａと壁取付部８２ａとからなる。
本体８１ａは、平板状の塩化ビニル樹脂被覆鋼板であり、壁取付部８２ａは本体８１ａの屋内側に立設されたものである。
床仕上げ材９ａは合成樹脂製の人工芝である。
９５ａはシール材である。
【００５５】
次に、このバルコニー床４４ａの施工方法ついて説明する。
図７に示すように、床根太４３ａの上に下側下地材５１ａを取り付け、この下側下地材５１ａの上に、ほぼ中央に隙間を設けて上側下地材５２ａを取り付けて、この隙間に溝５３ａを形成した状態にして下地材５ａを設ける。
一方、図８に示すように、塩化ビニル被覆鋼板を断面コ字形に折り曲げて窪み６１ａと突出部６９ａと鍔６２ａとからなる長尺体とし、窪み６１ａの屋外側先端を下方に折り曲げて水切り６４ａを形成し、屋内側端部に壁取付部６３ａを溶接して取り付けて溝部取付材６ａを製造する。
【００５６】
又、塩化ビニル樹脂被覆鋼板を、図９に示すように、折り曲げて、本体８１ａと壁取付部８２ａとからなるカバー材８ａを製造する。
そして、壁取付部６３ａを屋内側に立設させ、水切り６４ａを屋外側に垂下させ、図７に示すように、窪み６１ａを下地材５ａの溝５３ａの中に挿入し、鍔６２ａを溝５３ａの周縁部の下地材５ａに載せて、溝部取付材６ａを下地材５ａの上に取り付ける。
この水切り６４ａの下方に軒樋を取り付ける。
【００５７】
次に、溝部取付材６ａの鍔６２ａの上にシール材９５ａを塗布し、防水材７ａを上側下地材５２の上に取り付ける。
この際、図７に示すように、防水材７ａの側縁部を、溝部取付材６ａの鍔６２ａの上を通って窪み６１ａの中にほぼ水平に突出させ、このシール材９５ａの上から防水材７ａの側縁部を溝部取付材６ａの鍔６２ａに押し付けて防水材７ａを溝部取付材６ａに接着する。
【００５８】
次に、防水材７ａの側縁部にシール材９５ａを塗布し、カバー材８ａを取り付ける。
この際、カバー材８ａの中央部を溝部取付材６ａの突出部６９ａの上に載せ、カバー材８ａの両側縁部をシール材９５ａの上から防水材７ａの側縁部に押し付けて、カバー材８ａを防水材７ａに接着する。
【００５９】
この防水材７ａとカバー材８ａの上に床仕上げ材９ａを敷いて、バルコニー床４４ａを製造する。
その他の施工方法、例えば、バルコニー床４４ａを使用してバルコニーを製造する製造方法、建物ユニット、屋根パネル等の製造方法は実施例１とほぼ同じであるので、説明を省略する。
このようにして製造したバルコニー床４４ａを備えたバルコニー、建物ユニット、屋根パネル等を、実施例１と同様にして、施工現場に運搬し、施工現場で建物ユニットに取り付けてユニット建物を完成する。
【００６０】
このようにして完成したユニット建物では、防水材７ａが側縁部を窪み６１ａの縁から窪み６１ａの中に突出させた状態にして下地材５ａと溝部取付材６ａの鍔６２ａの上に取り付けられているので、防水材７ａの上に降った雨水は溝部取付材６ａの窪み６１ａの中に落下し、この窪み６１ａの中を流れ、水切り６４ａから樋、縦樋を経て地上に流れ落ちる。
そして、この防水材７ａの側縁部は窪み６１ａの中にほぼ水平に突出しているので、防水材７ａが熱膨張収縮しても、この窪み６１ａの中に突出している長さが長くなったり短くなるだけである。
従って、長年月使用しても防水効果が低下しない。
【００６１】
又、溝部取付材６ａが、窪み６１ａを下地材５ａの溝５３ａの中に挿入し、鍔６２ａを溝５３ａの周縁部の下地材に載せた状態に、取り付けられているので、溝部取付材６ａは上方から溝部取付材６ａに力が加わっても窪み６１ａや鍔６２ａや突出部６９ａが下方に移動しない。
【００６２】
そして、カバー材８ａは、中央部を溝部取付材６ａの突出部６９ａに載せ、両側縁部を防水材７ａの側縁部の上に載せた状態に、取り付けられているので、カバー材８ａは、両側縁部が防水材７ａの側縁で支持され、中央部が、溝部取付材６ａの突出部６９ａに支持されていて、この溝５３ａの上方のカバー材８ａの上に人が載っても窪まないようにない。
【００６３】
又、カバー材８ａの上面は平らで、しかも、カバー材８ａの両側縁部が防水材５ａの側縁部の上に載っているので、平板状の防水材５ａとカバー材８ａの上面とは、カバー材８ａの厚みだけの凹凸があるがこの凹凸は極めて小さく、床面全体がほぼ平らな面となっていて歩き易い。特に、床仕上げ材９ａの上は歩き易い。
又、このバルコニー床４４ａの防水構造に使用する部材は、溝部取付材６ａ、防水材７ａ、カバー材８ａというように、数が少なく、しかも、この使用する部材が簡単な構造をしていて製造し易く便利である。
【００６４】
又、溝部取付材６ａの鍔６２ａと防水材７ａの側縁部との間と、防水材７ａの側縁部とカバー材８ａの間とにシール材９５ａが設けられているので、この溝部取付材６ａの鍔６２ａと防水材７ａの側縁部との間と、防水材７ａの側縁部とカバー材８ａの間の防水性能が更に向上するし、防水材７ａが移動しなくなる。
しかも、このシール材９５ａが長年月使用している間に劣化してシール材９５ａに亀裂が生じても、この亀裂を通して浸入する雨水は溝部取付材６ａの窪み６１ａの中に落下するので下地材５ａまで漏れることがないし、この亀裂から浸入する雨水は少なく、従って、大雨のときでも、溝部取付材６ａの窪み６１ａの中の雨水が溢れるということがない。
尚、この実施例２では、突出部６９ａを１条設けているが、２条以上設けてもよい。
【００６５】

BACKGROUND OF THE INVENTION
The present invention relates to waterproof structures such as roofs and balcony floors and outer walls, and more particularly to waterproof structures suitable for balcony floors.
[0002]
[Prior art]
Conventionally, various waterproof structures such as roofs, floors of balconies and outer walls are known. For example, in Japanese Utility Model Publication Nos. 55-13521 and 10-114997, a waterproof material (described as a floor drainer or an impermeable floor material in the above publication) is attached on a balcony floor beam. The waterproof structure of the balcony floor is described.
Japanese Patent Application Laid-Open No. 9-209512 and Japanese Patent No. 2987746 describe a waterproof structure for waterproofing the surface of a base material on which linear grooves such as a roof, a balcony, and an outer wall are formed.
[0003]
That is, the waterproof structure disclosed in Japanese Patent Laid-Open No. 9-209512 is a long body composed of a U-shaped recess that is recessed to substantially the same depth as the groove and flat plate-like ridges provided on both sides of the recess. The groove mounting material, a long holding material having an engaging recess at the center, a flat waterproof material, and a fitting convex on the lower surface can be inserted into the recess of the groove mounting material. The groove attachment material is attached in a state where the recess is inserted into the groove and the ridge is placed on the base material on the peripheral edge of the groove, and the holding material is attached to the groove portion. The waterproofing material is inserted into the material recess, and the waterproofing material is attached with the end face facing the engaging recess of the holding material, and a slight gap is provided between the facing end faces. Overlap the side edge of the waterproof material and insert the engaging convex part into the recess from between the facing end faces of the waterproofing material. In a state of fitted into the engaging recesses of the lifting member, and the attached structure.
[0004]
In addition, the waterproof structure of Japanese Patent No. 2998746 is a waterproof material that covers the base material, and has a U-shaped recess with a shape along the inside of the groove on one side edge, and a flat plate provided on the tip side of the recess. A plate end receiving portion comprising a ridge, a rising portion that rises in the dent to approximately the same length as the depth of the dent, and a substantially horizontal horizontal portion provided at the tip of the rising portion. Provided on the other side edge portion is a V-shaped portion extending in a state of being bent substantially perpendicularly downward from the tip, and a hook portion that can be hooked on the plate end receiving portion, and is waterproof. The material is attached with the recess inserted into the groove, and the adjacent waterproof material is hooked on the plate end receiving portion provided in the already installed waterproof recess. It has a structure that is attached.
[0005]
[Problems to be solved by the invention]
However, the waterproof structure of the balcony floor described in Japanese Utility Model Publication Nos. 55-13521 and 10-114997 has a relatively small floor area, and it is only necessary to attach one waterproof material to the balcony floor. However, if the floor area of the balcony becomes large, it is necessary to connect a plurality of waterproof materials, and there is a problem that rainwater leaks from the connecting portions of the waterproof materials.
[0006]
Therefore, in order to waterproof the connection part where this waterproof material is piled up, we tried to provide a seal material between this polymerized waterproof material to make it waterproof, but the seal material deteriorated during many years of use. It was found that the sealing material was cracked and the rainwater leaked out from the polymerized waterproofing material by repeating the expansion and contraction due to the temperature difference between summer and winter.
[0007]
Further, the waterproof structure described in Japanese Patent Application Laid-Open No. 9-209512 and Japanese Patent No. 29987746 is provided with a groove in the base material, and a long body having a recess that has almost the same function as a ridge is provided in the groove. In addition, rainwater that has fallen on the waterproof material is allowed to flow into the recess, so that even if the waterproof material expands and contracts, rainwater does not leak, which is a preferable structure.
[0008]
However, in the waterproof structure described in the above-mentioned Japanese Patent Application Laid-Open No. 9-209512, a large number of members are required so as to be composed of the groove mounting material, the holding material, the waterproof material, and the coupling portion. For example, it has a complicated shape such as providing an engaging convex portion or a fitting concave portion, and is difficult to manufacture. In addition, this waterproof structure is suitable as a waterproof structure for waterproofing places where people are hardly placed such as roofs and outer walls, but when this waterproof structure is applied to floors on which people often sit like floors of balconies, When a person is placed on the bonding material above the groove, the fitting convex portion of the bonding material moves up and down in the engagement concave portion of the holding material and is unstable. If it is frequently moved up and down, there is a problem that the binding material moved downward does not return to its original shape, a recess is formed in this portion, and a water pool is generated.
[0009]
In the waterproof structure described in Japanese Patent No. 2998746, a dent, a ridge, a rising portion and a plate end receiving portion are provided on one side edge of the waterproof material, and a V-shaped portion is provided on the other side edge. It is difficult to manufacture and inconvenient, requiring a waterproof material with a complicated shape, such as providing a hook, and at the same time, this waterproof material has a complicated shape and is bulky. Is necessary, and there is a problem that the transportation cost becomes high. In addition, when this waterproof structure is applied to the floor of a balcony, a gap is formed between the waterproof material and the V-shaped portion of the adjacent waterproof material. Become ugly.
[0010]
Accordingly, an object of the present invention is a waterproof structure that waterproofs a base material in which a groove that does not leak rainwater is formed even when the waterproof material expands and contracts, and the number of members is small, and the members and the waterproof material are made into complicated shapes. It is another object of the present invention to provide a waterproof structure that does not have to be depressed and does not dent even if a person is placed above the groove.
[0011]
[Means for Solving the Problems]

[0012]
The invention according to claim 2 is a waterproof structure for waterproofing the surface of the base material on which linear grooves are formed, and is provided on both sides of the depressions which are recessed to substantially the same depth as the grooves. A long groove mounting material comprising a flat plate-shaped ridge and a protruding portion protruding upward at substantially the same height as the depth of the depression at the center of the depression, a flat waterproof material, and a flat shape The groove mounting material is mounted in a state where the recess is inserted into the groove of the base material and the ridge is placed on the base material of the peripheral portion of the groove, and the waterproof material is The side edge is projected from the edge of the recess into the recess, and is mounted on the base material and the groove mounting material, and the cover material is placed on the protruding portion of the groove mounting material. The both side edges are mounted on the side edges of the waterproof material.
[0013]
Furthermore, the present invention is as described above. According to the invention, a sealing material is provided between the flange of the groove mounting material and the side edge of the waterproof material, and between the side edge of the waterproof material and the cover material.
[0014]
(Function)
In the first aspect of the invention, the waterproof material is mounted on the base material and the groove mounting material with the side edge protruding from the edge of the recess into the recess. Rainwater that has fallen on the material falls from the tip of the waterproof material protruding into the recess into the recess of the groove mounting material.
Moreover, since the side edge of the waterproof material protrudes into the recess, even if the waterproof material is thermally expanded and contracted, the length of the waterproof material protruding into the recess is only increased or decreased. Accordingly, the waterproof effect does not deteriorate even after many years of use.
[0015]
In addition, the groove mounting material used in the invention described in claim 1 is composed of a dent recessed to substantially the same depth as the groove, and flat plate-shaped ridges provided on both sides of the dent.
And in this invention of this Claim 1, this groove part attachment material is attached in the state which inserted the hollow in the groove | channel of the base material, and mounted the collar | guard on the base material of the peripheral part of a groove | channel.

And in this invention of this Claim 1, this cover material is attached in the state which inserted the protrusion part in the hollow and mounted the both-sides edge part on the side edge part of a waterproof material. In this way, the cover material is supported by being placed on the heel and the waterproof material on the heel that is placed so that the side edges of the cover material do not move downward on the base material. However, it is placed on and supported by the bottom surface of the groove mounting member that is mounted so as not to move downward, so that it does not sink even if a person is placed on the cover material above the groove.
[0017]
Further, the upper surface of the cover material is flat, and both side edges of the cover material are placed on the side edges of the waterproof material. The flat waterproof material and the upper surface of the cover material are There is unevenness only in thickness, but this unevenness is small, and the entire floor surface is almost flat and easy to walk.
Thus, the waterproof structure according to claim 1 is a waterproof structure suitable for the floor of a balcony because the floor surface is flat and easy to walk even if a person is placed on the groove.
Further, the members used in the waterproof structure according to claim 1 are more than the members used in the waterproof structure described in JP-A-9-209512, such as groove mounting materials, waterproof materials, and cover materials. In addition, the member to be used has a simple structure and is easy to manufacture, and the waterproof material is flat and easy to carry.
[0018]
In the invention according to claim 2, since the waterproof material is attached on the base material and the groove attachment material with the side edge protruding from the edge of the recess into the recess, the waterproof material is waterproof. The rainwater that has fallen on the material falls into the recess of the groove mounting material from the tip protruding into the recess.
Moreover, since the side edge of this waterproof material protrudes almost horizontally into the recess, even if the waterproof material expands and contracts, the length protruding into this recess will only increase or decrease. It is. Accordingly, the waterproof effect does not deteriorate even after many years of use.
[0019]
Further, the groove mounting material used in the invention according to claim 2 is a depression recessed to substantially the same depth as the groove, a flat plate provided on both sides of the depression, and substantially at the center of the depression. It consists of the protrusion part which protruded upwards in the height substantially the same as the depth of a hollow.
In the invention according to claim 2, the groove mounting material is mounted in a state in which the recess is inserted into the groove of the base material and the ridge is placed on the base material of the peripheral portion of the groove.
Therefore, the attached groove part attachment material is in a state where the bottom surface of the recess is along the bottom surface of the groove, and the heel is along the surface of the base material of the peripheral part of the groove, and the groove part of the groove part attachment material from above, Even if a force is applied to the bottom surface of the dent or the protrusion protruding from the dent, the protrusion does not move, and the protrusion is almost the same height as the ridge.
[0020]
The cover material used in the invention of claim 2 is a flat plate-like long body.
In the invention according to claim 2, the cover member is attached in a state where the central portion is placed on the protruding portion of the groove mounting member and both side edges are placed on the side edge portions of the waterproof material.
Because of this, the cover material is supported by the side edges of the heel and the waterproof material on the side of the base material so that the side edges do not move downward on the base material, and the center part is attached to the groove It protrudes at almost the same height as the ridge of the member, and is supported by a protruding portion that does not move downward, so that it does not sink even if a person is placed on the cover material above the groove of the base material. In addition, although the height of the both-sides edge part and center part of a waterproof material changes only with the thickness of a waterproof material, this difference is small and does not become a problem.
[0021]
Further, the upper surface of the cover material is flat, and both side edges of the cover material are placed on the side edges of the waterproof material. The flat waterproof material and the upper surface of the cover material are Even if there is unevenness of only thickness, this unevenness is very small, and the entire floor surface is almost flat and easy to walk.
Thus, the waterproof structure according to claim 2 is a waterproof structure suitable for the floor of a balcony where the floor is flat and easy to walk even if a person is placed on the groove.
Further, the members used for the waterproof structure according to claim 2 are more than the members used for the waterproof structure described in JP-A-9-209512, such as groove mounting materials, waterproof materials, and cover materials. In addition, the member to be used has a simple structure and is easy to manufacture, and the waterproof material is flat and easy to carry.
[0022]
Furthermore, in the present invention, the above-described According to the invention, since the sealing material is provided between the flange of the groove mounting material and the side edge of the waterproof material and between the side edge of the waterproof material and the cover material, the groove mounting The waterproof performance between the heel of the material and the side edge of the waterproof material and between the side edge of the waterproof material and the cover material is further improved, and the waterproof material does not move.
[0023]
In addition, even if the sealing material deteriorates during use for many years and this sealing material cracks, rainwater that enters through this crack falls into the recess of the groove mounting material and may leak to the base material. In addition, there is little rainwater entering from the cracks, and therefore there is no overflow of rainwater in the recess of the groove mounting material even during heavy rain.
