Description

【0001】
【発明の属する技術分野】
本発明は壁用プレキャストコンクリート板および壁ならびにその構築方法に関するものである。
【0002】
【従来の技術】
上階と下階とのバルコニーの間の立ち上げ壁に沿って設けたマリオン壁は、図12に示すように、上部を上階のバルコニー25の下面にファスナー27で固定するとともに、下部を下階のバルコニー26の立ち上げ壁26aに固定していた。またマリオン壁28の構築は、上階と下階とのバルコニー25、26の間に壁用プレキャストコンクリート板29を設置した後、上部を上階のバルコニー25の下面にファスナー27で固定した後、下部と下階のバルコニー25、26の立ち上げ壁26aとの間にモルタル30を充填していた。
【0003】
【発明が解決しようとする課題】
しかし、上記のマリオン壁は、上部を上階のバルコニーの下面にファスナーで固定していたため、該ファスナーを隠すためのカバーを必要としていた。また、このカバーを設けたとしてもマリオン壁の上部にカバーで覆われたファスナーが露出するため見栄えが悪かった。
【0004】
本発明はこれらの問題に鑑みてなされたものであり、その目的は、見栄えが良く、かつ簡単に構築できる壁用プレキャストコンクリート板および壁ならびにその構築方法を提供することである。
【0005】
【課題を解決するための手段】
以上の課題を解決するため手段は、請求項1の発明が、プレキャストコンクリート板の小口部の一方に設けた凹溝内に受け金物が設置され、該受け金物は長孔を備えた上部プレートと、該上部プレートの下面に設けた断面凹形の受け体とからなり、該受け体には凹溝の側壁に設けた引きボルトがねじ込まれる一方、前記側壁に設けた押しボルトの先端部が当接されたことを特徴とする。
【0006】
請求項1の発明によれば、壁を簡単に構築することができる壁用プレキャストコンクリート板が提供できる。
【0007】
また請求項2の発明が、上階の床と下階の床との間に壁用プレキャストコンクリート板が設けられ、該壁用プレキャストコンクリート板の上部は小口部の受け金物に上階の床の下面から突出した接合ピンが挿入して面内方向に移動可能に接合され、壁用プレキャストコンクリート板の下部は下階の床に剛接合されたことを特徴とする。
【0008】
請求項2の発明によれば、上階の床と下階の床とはバルコニーも含むものであり、マリオン壁、外壁または間仕切壁のいずれもファスナーを隠すカバーを必要とせずに構築できるとともに、これらの壁によって層間変位を吸収することもできるようになる。
【0009】
また請求項3の発明が、上階の床と下階の床との間に壁用プレキャストコンクリート板を設置し、該壁用プレキャストコンクリート板の小口部の受け金物に上階の床から突出した接合ピンを挿入するとともに、前記受け金物の面外方向の位置を調整した後、壁用プレキャストコンクリート板の下部を下階の床に剛接合することを特徴とする。
【0010】
請求項3の発明によれば、上階の床と下階の床とはバルコニーも含むものであり、壁用プレキャストコンクリート板によりマリオン壁、外壁または間仕切壁のいずれを構築する場合、受け金物の面外方向の位置を調整するだけで壁用プレキャストコンクリート板の上部の位置合わせをすることができる。また受け金物を調整することにより接合ピンの取り付け誤差を吸収することができる。
【0011】
【発明の実施の形態】
以下、本発明の壁用プレキャストコンクリート板および壁ならびにその構築方法の実施の形態について説明する。
【0012】
図1の(1)は壁用プレキャストコンクリート板(以下、壁用PC板という)の背面図、(2)は(1)のA−A線断面図、図2の(1)は受け金物の斜視図、(2)は同断面図、図3は要部の背面図、図4は図3のB−B線断面図、図5の(1)は図3のC−C線断面図、(2)は同D−D線断面図である。
【0013】
壁用PC板1は、いわゆるフルプレキャストコンクリート板の上側小口部に設けた一対の凹溝2に受け金物3が設置されて構成されている。この受け金物3は、図2に示すように、長孔5を備えた上部プレート4と、この下面に設けた断面凹形の受け体6とから構成され、該受け体6の背板7が前板8より幅広に形成されている。
【0014】
受け金物3の上部プレート4は凹溝2の開口部を塞ぐとともに、凹溝2内の受け体6には操作溝9の固定板10の引きボルト11が一対ねじ込まれるとともに、これらの間に設置された押しボルト12の先端部が当接している。
【0015】
したがって、この引きボルト11と押しボルト12との操作で受け金物3が凹溝2内で面外方向に移動可能となる。例えば、引きボルト11を右に回すとともに押しボルト12を左に回すと受け金物3は前方に移動し、これとは反対に引きボルト11を左に回すとともに押しボルトを右に回すと受け金物3は手前側に移動する。このように凹溝2は受け体6が自由に移動できる大きさになっている。
【0016】
次に、壁の第1の実施の形態について説明する。図6〜図9は壁の第1の実施の形態であるマリオン壁13を示したものであり、上階の床と下階の床は上下のバルコニー14、15であり、これらのバルコニー14、15の間の立ち上げ壁14a、15aに沿って壁用PC板1が設けられ、受け金物3に上階のバルコニー14から突出した接合ピン16が挿入して上部が面内方向に移動可能に固定されるとともに、下部が下階のバルコニー15の立ち上げ壁15aに剛接合されている。
【0017】
前記接合ピン16は上階のバルコニー14に埋設されたインサートパイプ17から突出し、その先端部が上部プレート4の長孔5および受け体6内に挿入されている。この長孔5と受け体6とは面内方向に長く形成されているため、マリオン壁13の上部が面内方向に移動可能となって層間変位を吸収することができる構成となっている。また凹溝2と操作溝9とにはモルタル18が充填されている。
【0018】
また図10は、壁の第2の実施の形態であるマリオン壁19を示したものであり、接合ピン16がボルト20に代わった以外は第1の実施の形態のマリオン壁13と同じ構成である。第1の実施の形態のマリオン壁13においては接合ピン16が受け体6の底面に当接するまでインサートパイプ17から突出していたが、このボルト20は頭部のナット21が収納孔22の段部23に引っ掛かって下部だけが受け体6内に挿入されている。
【0019】
また図11は、壁の第3の実施の形態を示したものであり、上記のマリオン壁13、19の他に壁用PC板1を使用して外壁13aおよび間仕切壁13bを構築したものである。
【0020】
以下に、図6〜図9における壁の第1の実施の形態であるマリオン壁13に基づいて壁の構築方法について説明する。まず、図1に示す壁用PC板1、すなわち上側小口部に受け金物3が設置されたものを現場に搬入する。一方、前記壁用PC板1が設置される各階のバルコニー14、15…には接合ピン16が予め収納され、図9の(1)に示すように、止め板24で下側への突出を押さえている。
【0021】
次に、上記の壁用PC板1をクレーンで吊り上げて、図6に示すように、上階および下階のバルコニー14、15の間に設置して、上部の位置合わせを行うとともに上階のバルコニー14における止め板24を取り外して接合ピン16を上部プレートの長孔5と受け体6とに挿入する。このように接合ピン16が上階のバルコニー14内に収納されているため、壁用PC板1の位置合わせをした後に接合ピン16を受け金物3内に挿入することができるようになる。
【0022】
この接合ピン16が受け金物3に挿入されて壁用PC板1の上部が仮固定されると、図8に示すように引きボルト11と押しボルト12で受け金物3を移動させて面外方向の微調整を行う。この微調整、すなわち壁用PC板1の表面と上階のバルコニーの立ち上げ壁14aの表面とを一致させた後に凹溝2と操作溝9とにモルタル18を充填する。
【0023】
このように壁用PC板1の上部の固定が終わったら、下部を下階のバルコニー15の立ち上げ壁15aにモルタル18などで剛接合すると、図6に示すような、上部が面内方向に移動可能となったマリオン壁1が構築される。
【0024】
【発明の効果】
壁を簡単に構築できる壁用PC板を提供することができる。
【0025】
ファスナーを隠すカバーを必要とせず、かつ見栄えの良い壁を構築できるとともに層間変位を吸収することができる壁を構築することができる。
【0026】
壁用PC板の上部の位置合わせが、受け金物の面外方向の位置を調整するだけでできる。
【0027】
受け金物を調整することにより接合ピンの取り付け誤差を吸収することができる。
