【発明の属する技術分野】
この発明は、布基礎に部分的に設けられる土台を施工するアンカー土台基礎の施工方法、そのアンカー土台、およびアンカー土台設置治具セットに関する。
【0002】
【従来の技術】
従来、布基礎に部分的に設けられる土台を施工するのに、アンカーボルトを埋め込んで布基礎を打設し、そのアンカーボルトに土台を据え付けている。土台のレベル調整は、布基礎の天端面を基準にして行う。モジュールの位置指定は、アンカーボルトを位置決め用補助具などで位置決めすることにより行う。
【0003】
【発明が解決しようとする課題】
しかし、上記施工方法では、以下に挙げるような種々の問題点がある。
(1)土台のレベル調整の基準となる基礎天端面のレベルは、基礎コンクリート打設後に、レベラーを一様に流し込み、調整しているが、作業者の技量に左右されバラツキが生じる。また、基礎天端面レベルが許容範囲外となった部分は、煩雑な是正作業を要するので、施工性が低下する。
(2)建方のベース部品である土台は、アンカーボルトに据え付けられるが、布基礎に埋め込まれた後のアンカーボルトに据え付けるので、単独で位置指定することができず、建方時の最終段階で指定位置が被る結果となっている。
(3)基礎天端面の不陸に伴い、サッシ対角寸法不良が頻繁に発生している。
(4)コンクリート打設後のアンカーボルト位置精度不良による手直しが依然として発生している。
【0004】
この発明の目的は、布基礎に部分的に設けられる土台の施工性の向上、および土台の天端面の精度向上が図れるアンカー土台基礎の施工方法、そのアンカー土台、およびアンカー土台設置治具セットを提供することである。
【0005】
【課題を解決するための手段】
この発明のアンカー土台基礎の施工方法は、布基礎に部分的に設けられる土台を施工する方法であって、土台とアンカーボルトとを相互に組み立てた部材であるアンカー土台を準備する。このアンカー土台を、基礎型枠内の所定の据付位置に、土台配置定規および定規支持部品を介して設置する。定規支持部品は、土台配置定規をレベル調整可能に基礎型枠に設置する部品である。このようにアンカー土台の設置された基礎形枠内に基礎コンクリートを打設して養生することにより、アンカー土台のアンカーボルトが埋め込まれた基礎を構築する。
この施工方法によると、土台とアンカーボルトとを予め組み立てたアンカー土台とし、このアンカー土台の据え付けは、基礎コンクリートの打設前に行う。その据え付けには、土台配置定規および定規支持部品を用いる。このときに、アンカー土台天端面における水平および鉛直方向の施工精度を調節することができ、その後にコンクリート打設を行う。そのため、基礎天端面における厳しいレベル調整作業が不要となる。したがって、施工性が向上し、また作業者の技量に左右され難く、土台天端面の水平および垂直精度も向上する。
【0006】
この発明のアンカー土台基礎の施工方法において、次のように施工しても良い。配筋および基礎型枠の施工完了後、基礎型枠の長手方向の複数箇所におけるおおよそのアンカー土台据付位置に幅止め金物を据え付ける。定規支持部品を基礎型枠へ固定し、この定規支持部品の有するレベル調整ナットを基礎天端レベルのおおよその位置へ調整する。上記基礎型枠上に据え付けられた各幅止め金物にアンカー土台を順次配置する。基礎型枠の任意に選定した基準となる隅部より、基礎型枠の長手方向に並べて上記土台配置定規を順次組付ける。これら土台配置定規にアンカー土台を取付けた後、上記幅止め金物を除去して上記土台配置定規を上記定規支持部品の上記ナット上に載せる。隣合う土台配置定規を、上記基準となる隅部から順次ジョイント部材にて組付け、各定規支持部品を各々基準高さレベルに調整して固定し、基礎型枠に基礎コンクリートを打設する。なお、上記ナットへ載せるのは、座金を介して載せても良い。
この方法の場合、土台配置定規にアンカー土台を取付け、土台配置定規を定規支持部品のレベル調整ナット上に載せ、定規支持部品を基準高さレベルに調整することにより土台のレベル調整を行うので、土台のレベル調整を容易にかつ精度よく行うことができる。また、土台配置定規を、基礎型枠の基準となる隅部から長手方向に並べ、隣合う土台配置定規を順次ジョイント部材にて組付けるので、土台の位置指定を容易にかつ精度よく行うことができる。
【0007】
この発明のアンカー土台は、布基礎に部分的に設けられる土台とアンカーボルトとを相互に組み立ててなり、この組み立て状態で基礎型枠に設置されて上記アンカーボルトが布基礎に埋め込まれるものする。
この構成によると、アンカーボルトと共に、土台を基礎型枠に水平および鉛直方向に位置決めすることができ、その状態で基礎コンクリートの打設が行える。そのため、施工性が向上し、土台天端面の精度も向上する。また、土台を布基礎の施工段階で位置指定することができる。
【0008】
この発明のアンカー土台設置治具セットは、布基礎に部分的に設けられる土台と、この土台に相互に組み立てられたアンカーボルトとでなるアンカー土台を、基礎型枠上に位置決めして設置するものであって、基礎型枠上に設置されて定規支持レベルが調整可能な複数の定規支持部品と、基礎型枠の長手方向に並べて配置され、上記定規支持部品上に配置されてアンカー土台が取付けられる複数の土台配置定規とを含むものとしている。
この構成のアンカー土台設置治具セットによると、この発明の上記施工方法で施工できて、施工性が向上し、また作業者の技量に左右され難く、土台天端面の水平および垂直精度も向上する。
【0009】
【発明の実施の形態】
この発明の一実施形態を図1ないし図7と共に説明する。この実施形態に係るアンカー土台基礎の施工方法は、布基礎に部分的に設けられる土台を施工する方法であって、その施工途中の状態を、図1〜図3に平面図、正面図および側面図で示し、そのアンカー土台を図4に示す。この施工方法は、図4に示すように、土台2とアンカーボルト3とを相互に組み立てた部材であるアンカー土台1を準備する。このアンカー土台1を、図5(A)〜(C)に示す複数の定規支持部品5と、複数の土台配置定規6と、複数のジョイント部材7とを含むアンカー土台設置治具セット4を用いて、基礎型枠8(図3)の所定の位置に設置する。
【0010】
図4に斜視図で示すように、アンカー土台1の上面には、土台配置定規6に取付けるための複数の位置決め孔18が形成されている。アンカー土台1を構成する土台2は、溝形鋼からなる土台本体13の両端にエンドプレート14を溶接し、土台本体13の上下面13a,13b間に一対の補強板15,15を介挿すると共に、土台本体13の下面13bに水平プレート16を溶接して構成される。土台本体13の下面13b側に一対のアンカーボルト3,3がナット17で締結して垂直に支持される。土台本体13の上面13aに、上記位置決め孔18が形成されている。
【0011】
図1〜図3において、アンカー土台設置治具セット4は、アンカー土台1を基礎型枠8上に位置決めして設置するものである。このアンカー土台設置治具セット4における定規支持部品5は、基礎型枠8上に設置されて定規支持レベルが調整可能な部品である。この定規支持部品5は、図5(A)に示すように、下側ボルト21と、この下側ボルト21が貫通する上下一対の型枠固定用座金22,22と、下側ボルト21に螺合して前記座金22を基礎型枠8に押し付ける筒形ナット23と、この筒形ナット23に螺合する上側ボルト24とを有する。さらにこの定規支持部品5は、上側ボルト24に螺合し座金25を介して前記筒形ナット23の上端に押し当てられるナット26と、上側ボルト24に螺合するレベル調整ナット27と、上側ボルト24が貫通し上側ボルト24の前記レベル調整ナット27より上位置に配置される上下一対の定規固定用座金28,28と、上側ボルト24に螺合して前記座金28を土台配置定規6に押し付ける筒形ナット29とを備える。
【0012】
アンカー土台設置治具セット4における土台配置定規6は、基礎型枠8の長手方向に並べて配置されると共に、定規支持部品5上に配置されてアンカー土台1が取付けられる定規である。この土台配置定規6は、図5(B)に平面図で示すように、基礎型枠8と略同じ幅寸法とした金属製の平板状枠部材からなる。土台配置定規5は、基礎型枠8へ設置した状態で、基礎型枠8内への基礎コンクリート打設を可能とするためのコンクリート注入用の開口30と、この土台配置定規5へクランプ40を用いてアンカー土台1を取付けるときにクランプ40の配置を許容する開口31を有する。また、この土台配置定規5は、アンカー土台1を取付けるための複数の位置決め孔32と、定規支持部品5に支持させるための複数のボルト挿通孔33と、隣合う土台配置定規5,5同士を、ジョイント部材7を介して組付けるための複数の位置決め孔34を有する。
【0013】
アンカー土台設置治具セット4におけるジョイント部材7は、隣合う土台配置定規6,6同士を組付ける連結用の部材である。このジョイント部材7は、土台配置定規6と略同じ幅寸法とした金属製の平板部材からなり、土台配置定規6の位置決め孔34と整合する複数の位置決め孔35を両端部に有する。
【0014】
次に、このアンカー土台基礎の施工方法の具体的な手順を、図1〜図3、および図6,図7を参照して説明する。
先ず、図6(A)のように、配筋9(図3)および基礎型枠8の施工が完了した後で、基礎型枠8の長手方向の複数箇所におけるおおよそのアンカー土台据付位置に幅止め金物38を据え付ける。つぎに、図6(B)のように、定規支持部品5を基礎型枠8へ固定し、この定規支持部品5のレベル調整ナット27を基礎天端レベルのおおよその位置へ調整する。基礎型枠8への定規支持部品5の固定は、図3のように、定規支持部品5の下側ボルト21を基礎型枠8の上端フランジ8aのボルト挿通孔(図示せず)に挿通して、下側ボルト21が貫通する上下一対の型枠固定用座金22,22で前記上端フランジ8aを挟み、下側ボルト21に螺合する筒形ナット23で前記座金22を上端フランジ8aに締め付けることにより行う。
【0015】
ついで、図6(C)のように、基礎型枠8上に据え付けられた各幅止め金物38にアンカー土台1を順次配置する。この後、図7(A),(B)のように、基礎型枠8の(つまり構築される布基礎の)任意に選定した基準となる隅部より、基礎型枠8の長手方向に土台配置定規6を並べて配置し、これら土台配置定規6に位置決めピン39およびクランプ40を用いてアンカー土台1を取付ける。土台配置定規6の配置では、土台配置定規6のボルト挿通孔33(図5)を対応する定規支持部品5の上側ボルト24に挿通させた状態で、アンカー土台1の上に載置し、これにより土台配置定規6の位置決めを行う。また、土台配置定規6へのアンカー土台1の取付けでは、図2のように土台配置定規6の位置決め孔32(図5)と土台2の対応する位置決め孔18(図4)とに位置決めピン39を挿通させると共に、図1のように土台2と土台配置定規6とをクランプ40で把持することにより行う。なお、基礎型枠8の隅部に用いる土台配置定規6およびアンカー土台1は、基礎型枠8の直線部分に用いる土台配置定規6およびアンカー土台1とは若干形状が異なる(概形L字状とされる)が、機能は同じである。
【0016】
この後、図7(A),(B)のように、幅止め金物38を基礎型枠8から除去して、土台配置定規6を定規支持部品5のレベル調整ナット27上に載せ、隣合う土台配置定規6,6を、基準となる隅部から順次ジョイント部材7により組付け、各定規支持部品5を各々基準高さレベルに調整して固定する。ジョイント部材7による隣合う土台配置定規6,6の組付けでは、図1および図2のように、ジョイント部材7の位置決めピン35(図5)と土台配置定規6の対応する位置決め孔34(図5)とに位置決めピン39を挿通させ、必要に応じてジョイント部材7と土台配置定規6をクランプ40で把持することにより行う。定規支持部品5のレベル調整ナット27でレベル調整した土台配置定規6は、レベル調整ナット27の上位置の一対の定規固定用座金28で挟み、その座金28を図7(C)のように上側ボルト24に螺合させた筒形ナット29で土台配置定規6に押し付けることにより固定する。これにより、基礎型枠8内の所定の据付位置に土台配置定規6を介してアンカー土台1が設置される。このようにアンカー土台1の設置された基礎型枠8内に基礎コンクリートを打設して養生することにより、アンカー土台1のアンカーボルト3が埋め込まれた布基礎50(図3参照)を構築する。
【0017】
このように、このアンカー土台基礎の施工方法によると、土台2とアンカーボルト3とを相互に組み立ててなるアンカー土台1を基礎型枠8内の所定の据付位置に土台配置定規6を介して設置してから、基礎型枠8内に基礎コンクリートを打設するので、布基礎の天端面レベルを調整するなどの作業を要することなく、容易に土台2を指定位置にレベル調整して設置でき、施工性が向上する。
【0018】
また、この施工方法では、土台配置定規6にアンカー土台1を取付け、土台配置定規6を定規支持部品5のレベル調整ナット27上に載せ、定規支持部品5を基準高さレベルに調整することにより土台2のレベル調整を行うので、土台2のレベル調整を容易にかつ精度よく行うことができる。また、土台配置定規6を、基礎型枠8の基準となる隅部から長手方向に並べ、隣合う土台配置定規6,6を順次ジョイント部材7にて組付けるので、土台2の位置指定を容易にかつ精度よく行うことができる。
【0019】
さらに、この施工方法に用いるアンカー土台1は、布基礎に部分的に設けられる土台2とアンカーボルト3とを相互に組み立ててなり、この組み立て状態で基礎型枠8に設置されて前記アンカーボルト3が布基礎に埋め込まれるものとしているので、布基礎に対する所定の指定位置に土台2を容易にかつ精度良く設置できる。
【0020】
また、この施工方法に用いるアンカー土台設置治具セット4は、基礎型枠8上に設置されて定規支持レベルが調整可能な複数の定規支持部品5と、基礎型枠8の長手方向に並べて配置され、前記定規支持部品5上に配置されてアンカー土台1が取付けられる複数の土台配置定規6とを含むものとしているので、基礎型枠8上に定規支持部品5を設置し、この定規支持部品5上に配置する土台配置定規6にアンカー土台1を取付けてから、定規支持部品5で土台配置定規6の支持レベルを調整することにより、土台2のレベル調整を容易にかつ精度良く行うことができる。
【0021】
この実施形態におけるアンカー土台基礎の施工方法の利点をまとめると、つぎのようになる。
・土台天端面の精度向上(例えば、水平精度が±1mm以下、レベル位置公差が3 mm以下とできる)。
・基礎施工延べ作業工数の短縮(例えば、標準的な敷地面積の住宅で、6.0時間以上短縮される)。
・1棟当たりのトータルコストの低減。
・レベル位置不良によるグラインダーの研磨作業の排除。
・アンカーボルトの位置精度不良ゼロ。
・建方作業工数の軽減。
・サッシ対角不良の軽減。
