【発明の属する技術分野】
本発明は、止水板同士を連結するために用いる継手構造体および該継手構造体を用いる止水板の連結方法に関する。
【０００２】
【従来の技術】
コンクリート構造物を施工する場合、構造物を構成するコンクリートを一度に打設することは困難であり、すでに固まったコンクリートに新しいコンクリートを打ち込んで一体化する打継ぎが行われている。この打継ぎによって生じる打継部は、曲げ、剪断、引張りなどの強度上、防水機能上、耐久性上に問題があるために、コンクリートの乾燥収縮や温度変化による体積変化に対して変形が行えるように伸縮目地が設けられている。特に止水を要するコンクリート構造物の伸縮目地や打継部には、漏水を防止するために止水板が設けられている。止水板は、両端がコンクリート構造物に埋め込まれ、中央部が伸縮目地や打設部となるように設けられる。従来、止水板は、銅製またはステンレス製などの金属板が用いられていたが、近年においては、十分な変形能力や完全な復元力を有し、水圧に耐え、コンクリートに密着して水みちのつかない、耐久性の良い、施工が容易といった点からゴム製のものや塩化ビニル樹脂製のものが用いられている。また、上述した曲げなどの伸縮目地の変形に応じて止水板も変形できるように複雑な形状とされている。
【０００３】
伸縮目地や打継部に設けられる止水板同士の連結においては、単なる重ね合わせでは漏水の原因となりやすいために、止水板に銅板やステンレス板などの金属板を用いる場合においては突き合わせ溶接が行われている。また、上述したゴム製または塩化ビニル樹脂製の止水板を使用する場合においては、互いの止水板の先端部を溶着させることにより行われている。
【０００４】
しかしながら、上述した複雑な形状においては、止水板同士の面合わせが難しく、さらに溶接や溶着を行うことは困難であった。こうして溶接または溶着された止水板においては、溶接不良または溶着不良を招いている場合が多いといった問題があった。
【０００５】
【発明が解決しようとする課題】
本発明は、上述した止水板の施工に関し、溶着や溶接を行うことなく、適切に止水板同士を連結することができ、高い止水性を付与することができる継手構造体および該継手構造体を用いる連結方法を提供することを目的とする。

【発明の実施の形態】
以下、本発明を図面を参照して詳細に説明する。図１は、本発明の継手構造体を用いて止水板を連結し、連結した止水板を伸縮目地に配設したところを示した図である。図１に示す伸縮目地１は、構造物２のコンクリート施工する際、所定位置に設けられ、コンクリートの乾燥収縮や温度による体積変化による変形を可能にしている。また、伸縮目地１には、目地材が詰め込まれ隙間が埋められている。図１に示す止水板３は、構造物２の伸縮目地１に跨るように両端がコンクリート内部に埋め込まれるように配設され、伸縮目地１に詰め込まれた目地材の隙間を通して流れる水を止水するために用いられている。また、図１に示す止水板３は、鉄筋４の間に配設され、コンクリートとの密着を良好にするために断面に凹凸が設けられて付着面積が大きくされている。また、止水板３同士は、本発明の継手構造体５により連結され、止水板３と同様に伸縮目地１を跨ぐように設けられている。
【００１４】
図１に示す実施の形態では、伸縮目地１が水平方向に設けられていて、伸縮目地１に跨るように垂直方向に止水板３が設置されている。また、止水板３は、鉄筋４の間に配置されるとともに別の止水板３と継手構造体５を用いて連結され、まわりをコンクリートで固定されている。また、伸縮目地１には、セメントペースト、モルタル、アスファルト、樹脂モルタルなどの充填材が目地材として詰め込まれている。図１に示す本発明の継手構造体５は、両端に開口および嵌合部が設けられていて止水板３を挿嵌することにより互いに隣接する止水板３を連結することができるようになっている。以下、本発明の継手構造体５を、図２および図３に示す実施例を用いて詳細に説明する。
【００１５】
図２は、本発明の継手構造体の第１の実施例を示した図である。図２に示す継手構造体５は、止水板３同士を連結して隙間から漏水しないようにするために用いられる。図２（ａ）には、止水板３の一部を示し、図２（ｂ）には、本発明の継手構造体５の第１の実施例を示す。図２（ａ）に示す止水板３は、Ｖ字形を連ねた断面形状をしていて、同じ断面形状でかつ同じ大きさとされたまま一方向に延ばされている。また、図２（ｂ）に示す継手構造体５は、略矩形とされた断面の中央に図２（ａ）と同じ断面形状の開口６と、開口６に連続する開口６と同じ形状かつ同じ大きさのまま挿嵌方向に形設された嵌合部７が設けられている。
【００１６】
図２（ｂ）に示す嵌合部７は、所定の挿入長とされていて、止水板３が容易に抜けない長さとなっている。また、図２（ｂ）に示す継手構造体５は、継手構造体５の裏側にも同様の開口６および嵌合部７が設けられていて、図２（ａ）に示す止水板３を挿嵌できるようになっている。したがって、止水板３と隣接する止水板３とを継手構造体５に挿嵌させることにより、止水板３と隣接する止水板３とを互いに連結させることができる。
【００１７】
本発明の継手構造体５は、使用する止水板の材質によって金属製、塩化ビニル樹脂製、ゴム製といったものを用いることができる。近年においては、塩化ビニル樹脂製やゴム製の止水板が用いられており、本発明の継手構造体５においても適切に止水することができ、耐久性が良いものとして塩化ビニル樹脂製とすることができる。さらに、変形能力や水圧、水みちのつかないといった点においてゴム製とすることもできる。
【００１８】
また、本発明の継手構造体５は、略矩形に限らず、いかなる形状のものでも用いることができる。本発明の継手構造体５の開口６は、上述した止水板３を挿入することができるのであればいかなる形状または大きさであっても良い。本発明の継手構造体５の嵌合部７は、止水板３を適切に挿嵌させることができ、止水板３が容易に抜けない挿入長とすることができる。また、挿入長は、止水板３と嵌合部７との隙間を通して漏水する水を止水するためには長いほど効果的であるが、施工性を考慮して適切な長さとすることができる。さらに、本発明の継手構造体５の嵌合部７は、異なる形状の止水板３を連結することができるように互いに異なる形状または大きさとされていても良い。
【００１９】
図３は、本発明の継手構造体の第２の実施例を示した図である。図３に示す継手構造体５は、止水板３同士を連結して隙間から漏水しないようにするために用いられる。図３（ａ）には、止水板３の一部を示し、図３（ｂ）には、本発明の継手構造体５の第２の実施例を示す。図３（ａ）に示す止水板３は、断面が矩形とされた平板に、両端部に半円筒が上下に設けられ、また角柱が上下に、さらに中央部が中空とされた半円筒が設けられた形状とされている。図３（ｂ）に示す継手構造体５は、略矩形とされた断面の中央に図３（ａ）と同じ断面形状の開口６と、開口６に連続する開口６と同じ形状かつ同じ大きさのまま挿嵌方向に形設された嵌合部７が設けられている。
【００２０】
図３（ｂ）に示す嵌合部７は、所定の挿入長とされていて、止水板３が容易に抜けない長さとなっている。図３（ｂ）に示す継手構造体５は、継手構造体５の裏側にも同様の開口６および嵌合部７が設けられていて、図３（ａ）に示す止水板３を挿嵌できるようになっている。これにより、裏側に設けられた同様の嵌合部７にも、隣接する止水板３を挿嵌させて止水板３と隣接する止水板３とを互いに連結させることができるようになっている。
【００２１】
図４は、本発明の継手構造体により止水板を連結しているところを示した図である。図４に示す継手構造体５は、止水板３を挿入するための開口６と、止水板３を適切に挿嵌できる嵌合部７とが設けられている。また、継手構造体５には、裏側の面にも同様の嵌合部６が設けられ、隣接する止水板３が挿嵌できるようになっている。図４に示す実施の形態では、継手構造体５の一端の開口６に向けて止水板３を挿入し、止水板３を押し込むことによって、止水板３が嵌合部７に挿嵌されるようになっている。
【００２２】
また、図４に示す継手構造物５の他端の開口６に向けて隣接する止水板３を挿入し、隣接する止水板３を押し込むこんで嵌合部７に挿嵌する。こうすることにより、止水板３と隣接する止水板３とは、継手構造体５により連結される。連結された止水板３を図１に示す伸縮目地１などに設置することにより、止水板３同士の隙間からの漏水も防止することができる。また、従来においては、止水板３同士を溶接や溶着などして隙間を無くしていたが、継手構造体５を用いる連結方法により容易に連結して漏水も防止することができる。
【００２３】
また、止水板３を挿嵌した後に継手構造体５の開口６にコーキング材や接着剤を用いて封止することができる。本発明に用いることができるコーキング材としては、エポキシ樹脂、樹脂モルタル、レジンコンクリート、セメントモルタル、コンクリートなどを用いて止水板３と開口６との隙間を埋めることができる。また、エポキシ樹脂を原料とした接着材を用いて互いを接合させることで開口６または嵌合部７と止水板３との隙間を埋めることができる。本発明においては、上述したコーキング材や接着剤のほか隙間を埋めることができるのであればこれまで知られたいかなるものでも用いることができる。
【００２４】
また、本発明においては、打継部に止水板３を配置する場合には、すでに打設されたコンクリートに止水板３を挿入できる溝を設けておき、止水板３を挿入して継手構造体５を用いて連結し、隙間を充填材などを用いてシールした後に打継することで止水板３を設置することができる。
【００２５】
上述したように本発明の継手構造体および該継手構造体を用いる連結方法について説明してきたが、本発明においては、上述した実施の形態に限定されるわけではなく、使用する止水板に応じていかなる断面形状、大きさ、挿入長とされていても良い。また、使用する止水板の数に応じて必要な数の継手構造体を用いることができる。さらに、異なる止水板を用いて止水する場合には、異なる止水板を嵌合することのできる嵌合部を設けることができる。
【００２６】
【発明の効果】
上述したように、本発明の継手構造体および該継手構造体を用いる連結方法を提供することにより、止水板の施工に関し、溶着や溶接を行うことなく、適切に止水板同士を連結することができ、高い止水性を確保することができる。また、本発明の継手構造体および該継手構造体を用いる連結方法を用いることにより、構造物に止水板を設置する作業が容易となり、作業の効率化を図ることができる。
