【発明の属する技術分野】
本発明は免震ビル等の下部外周部に形成された目地部を覆う免震ビル等の目地装置に関する。
【０００２】
【従来の技術】
従来、免震ビル等の下部外周部に形成された目地部は、該目地部を構成する躯体が地震等によって上下方向および前後左右方向に揺れ動いても、隙間が生じないように防水ゴムシートを用いた目地装置を設置している。
【０００３】
【発明が解決しようとする課題】
従来の防水ゴムシートを用いた目地装置では防水を図ることができるが、断熱性や耐火性に欠けるという欠点があるとともに、地震等で免震ビル等が大きく揺れ動くと、防水ゴムシートを用いた目地装置では目地部に隙間が生じやすく、点検修理が必要にな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、十分な断熱性と耐火性が得られるとともに、地震等によって免震ビル等が大きく揺れ動いても、自動的に元の状態に戻って、目地部に隙間が生じるのを確実に防止できる免震ビル等の目地装置を提供することを目的としている。
【０００５】
また、本発明は火災時等に所定温度以上になると膨脹させて、目地部を強固に密封して火災の侵入を阻止したり、あるいは耐火体の動きによって耐火シートで確実に目地部を覆って、火災の侵入を阻止することができる免震ビル等の目地装置を提供することを目的としている。
【０００６】
本発明の前記ならびにそのほかの目的と新規な特徴は次の説明を添付図面と照らし合わせて読むと、より完全に明らかになるであろう。
ただし、図面はもっぱら解説のためのものであって、本発明の技術的範囲を限定するものではない。
【０００７】
【課題を解決するための手段】
上記目的を達成するために、本発明は免震ビル等の外壁面の下端部の下部に空間部を介して設置されたよう壁に、前記空間部へ突出して最適な目地部となるように設けられた下部見切壁、前記免震ビル等の外壁面の下端部に前記空間部へ突出して最適な目地部となるように設けられた上部見切壁の両方あるいはいずれか一方と、この上部見切壁あるいは下部見切壁に取付け具を介して密封状態で前記目地部を覆うように取付けられた耐火シートの内部に耐火綿、ロックウール等の耐火材が収納された耐火帯と、この耐火帯を所定温度以上になると膨脹できるように該耐火帯内に設けられた感熱膨脹材とで免震ビル等の目地装置を構成している。
【０００８】
【発明の実施の形態】
以下、図面に示す実施の形態により、本発明を詳細に説明する。
【０００９】

【００１０】
前記取付け具９、９Ａの一方の取付け具９は図４に示すように、アングル状の一方の取付け具本体１４と、この一方の取付け具本体１４の前記上部見切壁７の底面と当接する当接部材１４ａに所定間隔で形成された複数個のビス挿入孔１５と、この複数個のビス挿入孔１５と対応する部位の耐火シート取付け部材１４ｂにそれぞれ形成されたビス１６で固定する場合のドライバー等の挿入切欠部１７とで構成されている。
【００１１】
また、前記取付け具９、９Ａの他方の取付け具９Ａは図５に示すように、前記上部見切壁７の下部角部に複数本のビス１６で固定されるアングル状に形成された他方の取付け具本体１８と、この他方の取付け具本体１８の前記上部見切壁７の側面と当接する部位に所定間隔に形成された複数個のビス挿入孔１９とで構成されている。
【００１２】
上記構成の免震ビル等の目地装置１は、上部見切壁７の一方側の底面に複数本のビス１６によって一方の取付け具９を固定する。
しかる後、ほぼ中央部に感熱膨脹材１３を取付けた耐火シート１０の一端部１０ａを支持板２０と複数本のビス２１を用いて一方の取付け具９に密封状態で固定する。
【００１３】
次に、耐火シート１０内に耐火綿、ロックウール等の耐火材１１を目地部５に隙間が生じないように入れるとともに、耐火シート１０の他端部１０ｂを他方の取付け具９Ａに支持板２０と複数本のビス２１を用いて取付ける。
次に、他方の取付け具９Ａを上部見切壁７の他方側の角部に押し当て、複数本のビス１６で上部見切壁７に固定する。
【００１４】
上記のように取付けられた免震ビル等の目地装置１は、上部見切壁７に耐火帯１２が取付けられているため、地震等によって上下方向および前後左右方向に揺れ動いても、耐火帯１２が伸縮して、目地部５に隙間が生じることなく覆った状態を保つことができる。
また、火災が発生した場合には、その熱によって感熱膨脹材１３が作動して耐火帯１２を膨脹させ、目地部５に隙間が生じないように密閉することができ、火災の内部への侵入を効率よく阻止することができる。
【００１５】
