【発明の属する技術分野】
本発明はエレベータシャフトや免震ビル等の一方の建物の開口部の床面と目地部を介して側壁や塀を備える躯体や建物等の他方の建物との床面とを接続する床用目地装置に関する。
【０００２】
【従来の技術】
従来のこの種の床用目地装置は一方の建物の開口部の床面に一端部が左右方向にスライド移動可能に取付けられ、他端部が他方の建物の床面に支持された、目地部の幅寸法の約２倍の長方形状の目地プレートと、この目地プレートの目地部に位置する部位以外の他端部の上部を前後方向にスライド移動可能に覆うカバープレートとで構成されている。
【０００３】
【発明が解決しようとする課題】
従来の目地部を長方形状の目地プレートで覆う床用目地装置は、揺れ動き量を大きく設定した免震構造の建物では目地プレートの一端部を左右方向にスライド移動可能に取付けられた一方の建物が目地部の幅寸法がなくなるように揺れ動いた場合、該一方の建物と一体になって目地プレートが他方の建物方向にスライド移動するとともに、一方の建物の両端部の外壁面と他方の建物の側壁との間を伸縮可能に覆う壁用目地装置が傾斜状態となり、該壁用目地装置と目地プレートとの間に三角形状の目地部が開口するという欠点があった。
【０００４】
本発明は以上のような従来の欠点に鑑み、免震建物等で大きく揺れ動いても、目地プレートの両側部に目地部が開口して危険になるのを確実に防止することができる床用目地装置を提供することを目的としている。
【０００５】

【０００９】
１６、１６は前記一方の建物２の開口部３側の両壁面２ａ、２ａと前記他方の建物７の目地部側の側壁６、６との間を伸縮可能に覆う壁面用目地装置で、この壁面用目地装置１６、１６は異なる前後左右方向に一方の建物２と他方の建物７が揺れ動いても伸縮し、前後方向に回動してその揺れ動きを吸収することができる、従来から一般に使用されているものを使用している。
【００１０】
前記取付け金具９は図３に示すように、複数本のビス１７等によって一方の建物２の開口部３の床躯体４に固定されるクランク状の支持金具１８と、この支持金具１８に支持された前記目地プレート１１の一端部が、該支持金具１８から脱落するのを阻止する複数本のビス１７等によって該支持金具１８の上部の床躯体４に固定されるアングル状の脱落防止バー１９とで構成されている。
【００１１】
前記目地プレート１１は図５に示すように目地プレート本体２０と、この目地プレート本体２０の一端部の底面に取付けられた、前記取付け金具９の支持金具１８のガイドレール部１８ａをスライド移動する複数個のローラー２１と、前記目地プレート本体２０の他端部の底面に取付けられた前記凹部１０内をスライド移動する複数個のローラー２２とで構成されている。
【００１２】
前記カバープレート１２は図６に示すように、前記凹部１０より大きい寸法に形成され、該凹部１０の周縁部にカバープレート１２の厚さ寸法分のカバープレート支持凹部２３を形成し、該カバープレート支持凹部２３に複数本のビス２４等によってカバープレート１２を固定している。
なお、カバープレート１２の厚さ寸法の段差が生じてもさしつかえない場合には、直接凹部１０の外周部の床面８に複数本のビス２４等によって固定してもよい。
【００１３】
前記一対の補助目地プレート１４、１４は図７に示すように、前記目地プレート１１の両端部寄りの部位の底面に固定された内側および一方の建物２側が開口する薄い箱状のケース体２５と、このケース体２５内を先端部がスライド移動する先端部が四角形状で、後端部の内側部分が弧状に切欠き２６された補助目地プレート本体２７と、この補助目地プレート本体２７の後端部に形成された枢支金具２８の枢支ピン１３が挿入される枢支ピン挿入孔２９とで構成されている。

上記構成の床用目地装置１は地震等によって一方の建物２と他方の建物７とが異なる左右方向に揺れ動いた場合には、図８に示すように一方の建物２に対して目地プレート１１が左右方向にスライド移動して、その揺れ動きを吸収する。
また、図９に示すように、一方の建物の２の開口部３側の目地部５が広くなるように揺れ動いた場合、目地プレート１１の他端部が他方の建物７の凹部１０内を前後方向にスライド移動して、その揺れ動きを吸収する。
【００１６】
一方の建物２の開口部３側の目地部５が狭くなるように揺れ動いた場合、図１０および図１１に示すように、目地プレート１１が一方の建物２によって、他方の建物７方向に押し圧されるため、目地プレート１１の他端部は他方の建物７の凹部１０内へ押し込まれる。
この時、一対の補助目地プレート１４、１４の補助目地プレート本体２７、２７は目地プレート１１と一体に移動しないため、目地プレート１１の一方の建物２側へ突出し、壁面用目地装置１６、１６が傾斜面になっても、突出する補助目地プレート本体２７、２７によって目地部５が開口するのを確実に防止することができる。
【００１７】
また、このように目地部５が狭くなりかつ左右方向に揺れ動いた場合には、補助目地プレート本体２７、２７の弧状の切欠部２６、２６と一方の建物２の外壁面とが接触して、補助目地プレート本体２７、２７が目地プレート１１側へ押し圧され、目地部５が開口することなくかつ補助目地プレート本体２７、２７を損傷させることなく回動させることができる。
