Description

【０００１】
【産業上の利用分野】
本発明は、エキスパンションジョイントカバーに関するものである。
【０００２】
【従来の技術】
エキスパンションジョイントカバーの従来例を図５に示す。この従来例において、エキスパンションジョイントカバーは、建造物の躯体１０、１０に固定される固定部材２０、２０と、固定部材２０間に架設されるカバープレート３０と、カバープレート３０を表面から押さえつけるカバー体４０とから構成される。固定部材２０には、シート保持溝２２ａが開設されており、止水シート５０の端縁が圧入される。
【０００３】
【発明が解決しようとする課題】
しかし、上述した従来例おいて、カバー体４０は固定部材２０に形成された支持部７１に止着されて固定されるが、図５に示すように、両端縁を自由端として中間部のみが固定される構造を取るために左右自由端方向に揺れやすく、施工後のがたつき等を惹起しやすいという欠点を有する。
【０００４】
さらに、カバー体４０と固定部材２０とはパッキン７２を介して接触しているために、カバー体４０がぐらつきやすい点と相まって、当該部位からの浸水が生じやすく、躯体１０側にダメージを与えやすいという欠点をも有する。
【０００５】
本発明は、以上の欠点を解消すべくなされたもので、施工後の安定性に優れたエキスパンションジョイントカバーの提供を目的とする。
【０００６】
【課題を解決するための手段】
本発明に係るエキスパンションジョイントカバーは、図１に示すように、
所定間隔をおいて配置される建造物の躯体１０に固定される固定部材２０と、固定部材２０、２０間に架設されて躯体１０間の間隙Ｄを塞ぐカバープレート３０と、固定部材２０に固定され、固定部材２０と共働してカバープレート３０を挟持して保持するカバー体４０と、固定部材２０に両端縁を嵌合、保持されて躯体１０間の間隙Ｄ部に架設される止水シート５０とを有して構成される。
【０００７】
固定部材２０は、躯体１０への固定片２１の一端縁部に設けられ、止水シート５０の端縁を嵌合、保持するシート保持部２２と、前記固定片２１の他端縁部から鉛直に立ち上げられ、自由端部に固定片２１と平行なカバー固定片２３をシート保持部２２側に突設した立ち上がり壁２４を備え、カバー体４０は、カバー固定片２３に止着され、先端にカバープレート３０の表面に摺接するパッキン６０を保持するカバー片４１と、カバー片４１の他端縁から突設され、前記固定部材２０の立ち上がり壁２４に沿う支持片４２とを備える。
【０００８】
カバー体４０のカバー片４１と支持片４２との境界部には、Ｕ字状の折り返し部４３が設けられるとともに、固定部材２０には、折り返し部４３に挿入され、折り返し部４３の対向する内壁に当接する転動防止用突部２５が設けられる。
【０００９】
【作用】
固定部材２０に止着されるカバー体４０にはＵ字状の折り返し部４３が設けられ、該折り返し部４３内に固定部材２０の転動防止用突部２５が挿入される。しかして、カバー体４０は、基端側において、支持片４２を固定部材２０の立ち上がり壁２４に当接し、かつ、折り返し部４３の対向内壁が固定部材２０の転動防止用突部２５の外壁に当接することから、容易にぐらつくことがなくなり、設置安定性が向上する。
【００１０】
また、カバー体４０の折り返し部４３と躯体１０との間に形成される隙間にコーキング材を充填することにより、固定部材２０は完全にカバー体４０内に収納される状態となり、かつ、カバー体４０と躯体１０表面との間もコーキング材によりシールされることとなり、シール効果の向上が図られる。
【００１１】
【実施例】
以下、本発明の望ましい実施例を添付図面に基づいて詳細に説明する。
図１、図２に壁躯体１０、１０間に設置されるエキスパンションジョイントカバーの実施例を示す。この実施例において、壁躯体１０には、各々固定部材２０がボルト１１により止着されており、該固定部材２０に支持されるようにしてカバープレート３０が装着される。
【００１２】
固定部材２０は、ステンレス、あるいはアルミニウム材等により形成されており、固定片２１の端縁を躯体１０の縁部に一致させる状態で固定される。この端縁には、隣接する他の躯体１０側に向けて開口する溝状のシート保持部２２が設けられており、該シート保持部２２内に止水シート５０の圧入部５１が圧入される。シート保持部２２側の端縁を躯体１０の辺縁に沿わせて固定することは、位置出し等を簡単に行うために有効であり、シート保持部２２を形成する下方突起２２ｂと躯体１０との間には、適宜の隙間２２ｃが設けらる。この隙間２２ｃを設けることにより、圧入部５１が圧入する際に容易に下方突起２２ｂが隙間２２ｃ方向に弾性変形することができるようになり、止水シート５０の装着作業性を良好にすることができる。また、上記固定部材２０の上方突起２２ｄは上方、正確にはカバープレート３０側に折り返されてプレート支持片２６が形成される。
【００１３】
一方、固定部材２０の他端縁には、躯体１０外方に突出する立ち上がり壁２４が立設され、立ち上がり壁２４の上端から隣接する他の躯体１０側にカバー固定片２３が折曲形成される。カバー固定片２３は、ボルト締結作業時に干渉しない位置まで延設されており、その自由端近傍にネジ孔が設けられる。さらに、カバー固定片２３の基端部は外方に延長されて転動防止用突部２５が突設される。
【００１４】
カバープレート３０は、固定部材２０のプレート支持片２６により背面を支持された状態で装着され、該カバープレート３０を固定するために、固定片２１にカバー体４０が装着される。カバー体４０は、一端縁にパッキン６０を保持するカバー片４１の他端縁を略Ｕ字状に折り返すとともに、該折り返し部４３の自由端から躯体１０側にさらに支持片４２を折り返して形成され、カバー片４１を固定部材２０のカバー固定片２３にネジ止めして固定される。
【００１５】
上記折り返し部４３の対向する内壁間の間隔は、固定部材２０側の転動防止用突部２５の対向壁面間の間隔に略一致しており、設置状態において、転動防止用突部２５の対向壁面が折り返し部４３の内壁に当接するとともに、固定部材２０の立ち上がり壁２４が支持片４２に当接し、カバー体４０の転びが防止される。また、上記折り返し部４３の躯体１０表面に対向する壁面と、躯体１０表面との間には、隙間が形成され、該隙間にコーキング材８０が充填される。かかる構成の下、固定部材２０の表面部は概ねカバー体４０により覆われることとなり、かつ、躯体１０とカバー体４０間にはコーキング材８０が充填されるとともに、カバー体４０とカバープレート３０間はパッキン６０によりシールされるために、防水性能を飛躍的に高めることが可能になる。
【００１６】
図３、図４に本発明の他の実施例を示す。なお、本実施例の説明において、上述した実施例と同一の構成要素は、図中に同一の符号を付して説明を省略する。
この実施例は、壁躯体１０、１０’同士のコーナ部に装着されるエキスパンションジョイントカバーを示すもので、コーナ部を形成する一方の躯体１０表面には、上述したと同様の構成が採用される。また、カバープレート３０の端縁が垂直に対峙する側の躯体１０’に固定される固定部材２０’は、躯体１０’への固定片２１の一端縁から他の躯体１０側に突出し、シート保持部２２を先端に備えたシート保持片２７を有し、他の躯体１０側に端縁を嵌合固定される止水シート５０の他端縁が保持される。また、シート保持部２２の上部には、カバープレート３０の背面を支持するプレート支持片２６が突設されるとともに、固定片２１の上端には、上述した実施例と同様に、立ち上がり壁２４、転動防止用突部２５、およびカバー固定片２３が設けられる。
【００１７】
一方、この固定部材２０’に止着されるカバー体４０’は、上述した実施例と同様に、カバー片４１、折り返し部４３、支持片４２を備えており、折り返し部４３と躯体１０との間に形成される隙間にコーキング材８０が充填されてシールされる。
【００１８】
【発明の効果】
以上の説明より明らかなように、本発明によれば、カバー体が容易にぐらつくことがないために、設置の安定性を向上させることができる。
