Description

本発明は床形成方法および床形成構造に関する。さらに詳しくは、コンクリートスラブと梁とを一体化してなる床形成方法および床形成構造に関する。
従来より、梁１００の剛性や耐力の向上を図る観点から、図４に示すように、梁１００の上フランジ１０１にスタッドボルト１２０を植設し、このスタッドボルト１２０をコンクリートスラブ１３０に固着してコンクリートスラブ１３０を梁１００に一体化してなる合成梁Ｂが知られている。
しかしながら、かかる合成梁Ｂにおいては、コンクリートスラブ１３０と梁１００との分離が困難であるため、梁１００の再利用が困難であるという問題がある。この問題は、循環型社会構造の構築が急務とされている現状において、大きな問題となっている。
本発明はかかる従来技術の課題に鑑みなされたものであって、コンクリートスラブと梁との分離が容易になし得る床形成方法および床形成構造を提供することを目的としている。
本発明の床形成方法は、梁を柱に接合する手順と、スラブ受け部材を梁に接合して組立材となす手順と、コンクリートスラブ形成領域に対応させて型枠を形成する手順と、前記コンクリートスラブ形成領域に鉄筋を配筋する手順と、前記型枠内にコンクリートを打設する手順と、所定の養生の後、脱型する手順とを含んでいることを特徴とする。
本発明によれば、梁とコンクリートスラブとの分離が容易となり、しかも梁の再利用が可能となるという優れた効果が得られる。
以下、添付図面を参照しながら本発明を実施形態に基づいて説明するが、本発明はかかる実施形態のみに限定されるものではない。
本発明の一実施形態に係る床形成方法が適用されてなる床形成構造を図１に概略図で示す。
床形成構造Ｋは、図１に示すように、梁１と、コンクリートスラブ２と、梁１とコンクリートスラブ２との間に介装されるスラブ受け部材３とを主要構成要素として備えてなるものとされる。
梁１は、上フランジ１ａにスタッドボルトが植設されておらず、かつスラブ受け部材３を固定するためのボルト挿通孔（図示省略）が上フランジ１ａ設けられている他は、従来の梁と同様とされている。なお、符号１ｂは下フランジを示す。
コンクリートスラブ２は、スラブ受け部材３に植設されたスタッドボルト４が固着されることによりスラブ受け部材３に一体化されている他は、従来のコンクリートスラブと同様とされている。なお、符号２ａは鉄筋を示す。
スラブ受け部材３は、上フランジ３ａの幅が下フランジ３ｂの幅より狭くされた異形Ｈ型鋼を補強リブ５により補強してなるものとされ、上フランジ３ａに例えば２００ｍｍ〜４００ｍｍピッチでスタッドボルト４が植設されている。このスラブ受け部材３の梁１へのボルト・ナット留めは、いわゆるＳ基準で組立材とみなされるピッチでなされる。つまり、細長比が５０以下となるようなピッチでボルト・ナット留めがなされる。
図２および図３に、スラブ受け部材３の端部を示す。図２および図３に示すように、スラブ受け部材３は、柱Ｃとは接合されずに縁切りがなされている。なお、図３に示す例においては、スラブ受け部材３の下フランジ３ｂが梁１と柱Ｃの仕口との接合部における目板に兼用されている。
次に、かかる構成とされている床形成構造Ｋの施工について説明する。
手順１：梁１を柱Ｃに接合する。
手順２：梁１にスラブ受け部材３をボルト・ナット留めにて接合して組立材となす。
手順３：コンクリートスラブ２形成領域に対応させて定法にて型枠を形成する。
手順４：定法にてコンクリートスラブ２を形成する領域に鉄筋２ａを配筋する。
手順５：型枠内にコンクリートを打設する。
手順６：所定の養生の後、脱型する。
これらの一連の手順により、梁１にコンクリートスラブ２が一体化された床形成構造Ｋが完成する。
また、この床形成構造Ｋの解体においては、スラブ受け部材３のボルト・ナット留めを解除することにより、コンクリートスラブ２を梁１から分離させる。
このように、本実施形態においては、梁１とコンクリートスラブ２との間にスラブ受け部材３を梁１とボルト・ナット留めにて介装するようにしているので、コンクリートスラブ２の梁１からの分離が、梁１の再利用可能な状態でなし得る。また、梁１とスラブ受け部材３とが組立材とされているので、梁１の撓みを小さくすることができる。この効果は、梁１のスパンが長大化した場合に特に有効となる。
なお、コンクリートスラブ２もブロック化しておけば、コンクリートスラブ２とスラブ受け部材３とが一体化されているので、コンクリートスラブ２およびスラブ受け部材３の再利用も可能となる。
以上、本発明を実施形態に基づいて説明してきたが、本発明はかかる実施形態のみに限定されるものではなく、種々改変が可能である。例えば、実施形態ではスラブ受け部材３は異形Ｈ型鋼とされているが、上下フランジの幅が等しい通常のＨ型鋼とされてもよい。
本発明は、コンクリートスラブが用いられている床に適用できる。
本発明の一実施形態に係る床形成構造の概略図である。 同床形成構造における端部の一例の概略図である。 同他の例の概略図である。 従来の床形成構造の概略図である。
