【発明の属する技術分野】
本発明は、建物の独立基礎や布基礎などを構成するために、基礎地盤上に立設してアンカーボルトを支持すると共に、アンカーボルトの上端ねじ部を突出する態様で基礎コンクリート中に埋設されるアンカーボルトの支持装置に関する。
【０００２】
【従来の技術】
この種のアンカーボルトの支持装置は、アンカーボルトの上端ねじ部を介して建物の柱や土台に連結し、柱や土台からの応力を基礎に伝達すべく基礎コンクリート中に埋設して建物の独立基礎や布基礎などを構成するが、例えば独立基礎の一つである露出形固定柱脚の代表的な工法としては、特許文献１で提案されているようなベースパック工法があり、特許文献２のような改良提案もある。

図１は、特許文献２で提案したアンカーボルトの支持装置１の一実施形態を示すが、基礎地盤２の捨てコンクリート上に設けたベース部１Ａと、ベース部１Ａから立設した支柱部材３と、支柱部材３の上端側に設けたアンカー保持部１Ｂと、アンカー保持部１Ｂを介して支柱部材３に連結されるアンカーボルト４と、アンカーボルト４の上端側に設けたテンプレート部１Ｃで構成されている。
【０００５】
ベース部１Ａは、左右に平行配置した一対の第１のベース部材５，５と、前後に平行配置した一対の第２のベース部材６，６を備え、第１のベース部材５はＬ字状で水平片５ａをウォールアンカー７とナット８で基礎地盤２上に固着すると共に、垂直片５ｂには支柱部材３の下端側をボルト９とナット１０で固着し、第１のベース部材５，５の間には第２のベース部材６，６を架設し、両端側をボルト１１とナット１２で固着して連結する。
【０００６】
アンカー保持部１Ｂは、Ｌ字状の支柱部材３に方形状の保持部材１４をボルト１３で固着し、保持部材１４内にアンカーボルト４を挿通して所望の高さ位置に設定し、支柱部材３に螺合した連結ボルト１５を締め付けて、アンカーボルト４を支柱部材３に連結保持させており、特に支柱部材３の角部からアンカーボルト４を遠ざかる方向に押圧し、支柱部材３の角部とアンカーボルト４との間に空隙を設け、打設するコンクリートの粗骨材が充填できるようにしている。
【０００７】
テンプレート部１Ｃは、４枚のテンプレート１６を互いに直交するようにして方形状に組み合わせ、テンプレート１６の角部にアンカーボルト４の上端ねじ部４ａを挿通させると共に、上端ねじ部４ａに螺合させた上下一対のナット１７によってテンプレート１６を挟持し、これによって各アンカーボルト４の相互間隔が規定される。
【０００８】
このようなアンカーボルトの支持装置では、支持装置の中心を柱や土台の取付け位置中心と正確に一致させるために、テンプレート部１Ｃにおけるアンカーボルト４の上端ねじ部４ａの高さ位置を、アンカー保持部１Ｂによって調整して垂直（Ｚ軸）方向の位置決めすると共に、支柱部材３を介して上端ねじ部４ａの前後及び左右位置を、ベース部１Ａによって調整して水平（Ｘ軸，Ｙ軸）方向の位置決めする必要がある。
【０００９】
しかしながら、特許文献１，２などの従来技術におけるアンカーボルトの支持装置１の場合には、アンカー保持部１Ｂで上端ねじ部４ａの上下位置を調整して垂直（Ｚ軸）方向の位置決めするのは容易であるが、ベース部１Ａによって上端ねじ部４ａの左右及び前後位置を調整して水平（Ｘ軸，Ｙ軸）方向の位置決めする点については、必ずしも十分な構造ではなかった。
【００１０】
すなわち、各支柱部材３の下端側を支持するベース部材５，６が方形枠状に一体化されており、基礎地盤２に打設した捨てコンクリート上面の不陸等の影響をベース部１Ａの全体で受けるので、水平（Ｘ軸，Ｙ軸）方向の位置決め調整を全ての支柱部材３に対して大幅に行う必要が生ずると共に、ベース部材５，６の相互干渉で各支柱部材３を個別に位置決め調整を行うことが困難であった。
【００１１】
そこで、水平（Ｘ軸，Ｙ軸）方向の位置決め調整を容易に行うことを可能にする提案を、本件出願人は先に特願２００２−１１１６４２号（先行技術１）及び特願２００２−２１２４１７号（先行技術２）で行っているが、これらの先行技術１，２の場合には、水平方向の位置決め調整を行った際にウォールアンカーに引き抜き力が作用すると共に、ベース部材が基礎地盤の捨てコンクリート上面から離間して支持力を低下させる恐れがあった。
【００１２】
そこで、先行技術１，２の場合と同様又はそれ以上に水平（Ｘ軸，Ｙ軸）方向の位置決め調整を容易に行うことを可能にすると共に、先行技術１，２の課題であったウォールアンカーに引き抜き力が作用したり、ベース部材が基礎地盤から離間することをなくして支持力の低下を防止することを可能にした提案を、本件出願人は先に特願２００２−３１７１２３号（先行技術３）で行った。
【００１３】
図２は、先行技術３によるアンカーボルトの支持装置におけるベース部２０Ａを示すが、ベース部材２１は水平片２１ａと垂直片２１ｂで形成した断面形状がＬ字状で、水平片２１ａは基礎地盤中に埋設したウォールアンカー２２にナット２３で固着すると共に、垂直片２１ｂにはボルト２４とナット（図示を省略）を介して支柱部材２５の下端側が連結されている。
【００１４】
支柱部材２５は、Ｘ方向に沿った第１支柱片２５ａとＹ方向に沿った第２支柱片２５ｂで形成した断面形状がＬ字状で、第２支柱片２５ｂには（図示の実施形態では、方向性をなくして互換性を持たせるように第１支柱片２５ａにも）ボルト２４のねじ軸が遊嵌する遊動取付孔２６を設け、第１支柱片２５ａには調整ねじ筒２７が溶接などによって固着され、調整ねじ２８を螺合している。
【００１５】
ベース部２０Ａは、調整ねじ筒２７に対して調整ねじ２８の螺合状態を可変して、ねじ頭部を水平片２１ａの上面に圧接させて支圧板にして第１支柱片２５ａを押し上げ、第２支柱片２５ｂを介して垂直片２１ｂをＸ方向の一方向ｘ１に撓み変形させ、これによって支柱部材２５を所望の傾斜状態に保持できるので、支柱部材２５の上端側に連結したアンカーボルトの上端ねじ部の水平位置を、Ｘ方向に位置決め調整することができる。
【００１６】
また、ボルト２４に螺合しているナットを緩めた状態で支柱部材２５をＹ方向の一方向ｙ１又は他方向ｙ２に押圧すると、ボルト２４のねじ軸がルーズホールによる遊動取付孔２６内で遊動し、ナットを締め直すと支柱部材２５を所望の傾斜状態に保持できるので、支柱部材２５の上端側に連結したアンカーボルトの上端ねじ部の水平位置を、ｙ方向に位置決め調整することができる。
【００１７】
このベース部２０Ａの場合には、支柱部材２５をＸ方向の他方向ｘ２に位置決め調整する際は、ベース部２０Ａの対向位置に同様の構成によるベース部を設け、このベース部の調整ねじ筒に対して調整ねじの螺合状態を可変して、対向位置の支柱部材を他方向ｘ２に傾斜状態にすることによって、テンプレート部を介してベース部２０Ａ側の支柱部材２５及び垂直片２１ｂを位置決め調整する。
【００１８】
このようにして、垂直（Ｚ軸）方向の位置決め調整が可能なアンカー保持部を介して、複数の各支柱部材の上端側に各アンカーボルトを装着すると共に、各支柱部材が立設されるベース部にＸ軸及びＹ軸に沿って位置決めする水平方向の位置決め調整部分を設けると、各支柱部材をそれぞれ個別にＸＹＺ方向に調整することが可能となり、各アンカーボルトの上端ねじ部を柱の取付け位置と正確に一致させることができる。
【００１９】
【発明が解決しようとする課題】
しかしながら、改善した先行技術３によるアンカーボルトの支持装置にも改善の余地が残されており、例えばＸ軸方向に沿った位置決め調整において、ｘ２方向又はｘ１方向（図２の状態を１８０度回転させて使用した状態）のいずれか一方を調整する際に、対向位置のベース部との間で完全に相互干渉がない状態で個別に調整することが容易でないと共に、布基礎などに適用する場合のように一本のアンカーボルトで使用する際には一方向のみの調整になってしまう。
【００２０】
また、アンカー保持部の構成において、図１で示すようにアンカーボルトを支持部材の角部から遠ざかる方向に連結ボルトで押圧し、支柱部材の角部とアンカーボルトとの間に空隙を設けると、打設するコンクリートの粗骨材が充填できるように改善されるが、これを更に改善して支持部材の上端側角部に対して、打設するコンクリートの粗骨材がより多く充填できることが望ましい。
【００２１】
そこで本発明では、これらの課題を解決し得るアンカーボルトの支持装置の提供であって、アンカーボルトに対する水平方向の位置決め調整を行う際に、ウォールアンカーに引き抜き力が作用したり、ベース部材が基礎地盤から離間することをなくして支持力の低下を防止すると共に、水平位置決め調整におけるＸ軸方向とＹ軸方向の相互干渉の低減及び、各アンカーボルト毎に単独で水平位置決め調整を容易且つ迅速に行うことを可能にし、独立基礎に加えて布基礎にも適用できるようにしたことを第１の目的とする。
【００２２】
また、支柱部材に対してアンカーボルトをＺ軸方向に沿って高さ調整可能に連結するアンカー保持部における連結構造を改善し、支持部材に対して打設するコンクリートの粗骨材が上端側角部により多く充填できるようにし、アンカーボルト及び支柱部材に対するコンクリートの付着力を高め、地盤に対する支持力を増強したことを第２の目的とする。
【００２３】
【課題を解決するための手段】
本発明は、基礎地盤上に設けたベース部に支柱部材を立設状態で連結し、支柱部材の上端側にはアンカーボルトの上下（Ｚ軸）位置を調整する垂直調整部を介してアンカーボルトを連結すると共に、ベース部にはアンカーボルトの左右及び前後位置を調整する水平調整部を介して支柱部材を連結し、これらを基礎コンクリート中に埋設して上端側に建物の柱又は土台を取り付けるアンカーボルトの支持装置を実施対象とし、独立基礎及び布基礎の双方に適用できる。
【００２４】
本発明のアンカーボルトの支持装置では、前記水平調整部は、支柱部材を左右（Ｘ軸）方向又は前後（Ｙ軸）方向のいずれかの一方へ位置決め調整する第１の水平調整部と、支柱部材を左右（Ｘ軸）方向又は前後（Ｙ軸）方向のいずれかの他方へ位置決め調整する第２の水平調整部を備え、これら第１及び第２の水平調整部は、１本のアンカーボルト毎にそれぞれ設けると共に、鉛直状態に支持した支柱部材を時計方向及び反時計方向に傾斜できるようにした。（請求項１）
【００２５】
このアンカーボルトの支持装置によると、各アンカーボルトを相互に干渉させることがない状態で、各アンカーボルトに対して個別で且つ双方向に水平調整を行うことができるので、調整作業を容易にすると共に調整の精度を高めることが可能であり、また原則的に１本のアンカーボルトを用いる布基礎にも適用することができる。
【００２６】
前記支柱部材は、第１支柱片と第２支柱片でＬ字状に形成すると共に、前記ベース部は、基礎地盤上にウォールアンカーで固着された支圧板と、水平片と垂直片でＬ字状に形成した第１ベース部材と、第１及び第２の垂直片でＬ字状に形成した第２ベース部材を備え、水平片を支圧板に固着した第１ベース部材の垂直片の両側に配置した支柱部材の第２支柱片と第２ベース部材の第２垂直片を、支柱部材の第２支柱片に形成したルーズホールによる遊動取付孔に挿通した連結ボルトとナットで連結すると共に、支圧板を反力受けにした高さ調整用ねじ手段を支柱部材の第２支柱片及び第２ベース部材の第１垂直片に設けて前記水平調整部を構成する形態を採ることができる。（請求項２）
【００２７】
この実施形態によると、連結ボルトに対するナットの螺合を緩めた状態にすると、ルーズホールで形成した遊動取付孔とねじ軸との間で遊動が可能であるから、この遊動範囲内で支柱部材をＸ又はＹのいずれか一方向に傾斜させ、上部に連結したアンカーボルトに対する水平方向の位置決め調整ができると共に、支圧板を反力受けとした高さ調整ねじ手段を調整し、支柱部材の第２支柱片及び第２ベース部材の第１垂直片を押し上げることで、第１ベース部材の水平片を鋭角状又は鈍角状に撓み変形させ、支柱部材をＸ又はＹのいずれか他方向に傾斜させ、上部に連結したアンカーボルトに対する水平方向の位置決め調整ができるが、構成が簡単で安価に提供でき且つ調整作業も容易である。
【００２８】
また、本発明による別のアンカーボルトの支持装置では、前記垂直調整部は、支柱部材の上端側に下部側を固着した連結部材と、連結部材の上部側に固着して内部にアンカーボルトを遊嵌状態で挿通する通孔を形成する保持部材と、前記連結部材又は保持部材に設けたねじ孔に螺合すると共に、ねじ軸の先端が前記通孔内に突出してアンカーボルトを支持する押さえねじで構成したアンカー保持部である。（請求項３）
【００２９】
このアンカーボルトの支持装置によると、従来技術のように支柱部材の上端側にアンカーボルトが挿通されいないので、上端側に十分な空隙部を確保することができ、アンカーボルトの支持装置を基礎コンクリート中に埋設した際に、コンクリート中に混合した粒径の大きな粗骨材も十分に充填されて強固な支持力が得られる。
【００３０】
前記アンカーボルトの支持装置における垂直調整部は、請求項３のアンカー保持部で構成されている形態を採ることができる（請求項４）が、この実施形態によると、請求項１〜３の効果を併せ持ったアンカーボルトの支持装置になる。
【００３１】
【発明の実施の形態】
以下に、本発明によるアンカーボルトの支持装置について、本発明を適用した好適な実施形態を示す添付図面に基づいて詳細に説明するが、図３はアンカーボルトの支持装置３０の全体正面図、図４は同装置３０の第１の実施形態による全体平面図、図５は同装置３０の第２の実施形態による全体平面図、図６は同装置３０の第１の要部となるベース部の第１の実施形態による斜視図、図７は同装置３０の第１の要部となるベース部の第２の実施形態による斜視図、図８〜１２は同装置３０の第２の要部となるアンカー保持部の第１〜５の実施形態による斜視図、をそれぞれ示す。
【００３２】
支持装置３０は、基礎地盤３１の捨てコンクリート上に設けたベース部３０Ａと、ベース部３０Ａから立設した支柱部材３２と、支柱部材３２の上端側に設けたアンカー保持部３０Ｂと、アンカー保持部３０Ｂを介して支柱部材３２に連結されるアンカーボルト３３と、アンカーボルト３３の上端側に設けたテンプレート部３０Ｃで構成されている。
【００３３】
図３〜５は、建物の柱に連結する露出形固定柱脚として独立基礎に適用した支持装置３０をの実施形態であって、複数本の（図面では４本）各アンカーボルト３３の上端側に設けたテンプレート部３０Ｃでは、上端ねじ部３３ａに螺合する上下のナット３５でテンプレート３６が狭持されており、ベース部３０Ａには基礎地盤３１上に載置する支圧板３４が設けられている。
【００３４】
ベース部３０Ａは、図４で示す第１の実施形態の場合には、各アンカーボルト３３に対して個別に設けた支圧板３４Ａを使用し、図５で示す第２の実施形態の場合には、左右に隣接する２本のアンカーボルト３３対して共通に設けた支圧板３４Ｂを使用しているが、各支圧板３４Ａ，３４Ｂは板面に穿設した取付け孔３７に、基礎地盤３１に埋設したウォールアンカー３８を挿通してナット３９で固着している。
【００３５】
ベース部３０Ａは、図６で示すように断面形状がＬ字状で支圧板３４（３４Ａ又は３４Ｂ）上に装着される第１及び第２ベース部材４０，４１を備え、第１ベース部材４０は水平片４０ａを支圧板３４の上面に載置してウォールアンカー３８とナット３９で固着すると共に、垂直片４０ｂは支柱部材３２の第２支柱片３２ｂに宛った状態で、支圧板３４上に起立させている。
【００３６】
また、第２ベース部材４１は第２垂直片４１ｂを垂直片４０ｂの内面に宛った状態で起立させ、支柱部材３２の第２支柱片３２ｂと第１ベース部材４０の垂直片４０ｂ及び、第２ベース部材４１の第２垂直片４１ｂは、第２支柱片３２ｂに形成したルーズホールによる遊動取付孔３２ｃに連結ボルト４２を挿通させ、ナット４３によって固着連結すると共に、第１垂直片４１ａは支圧板３４の上面と離間した状態で起立されている。
【００３７】
また、支柱部材３２の第１支柱片３２ａには溶接その他の固着手段で取付けた調整ねじ筒４４と、調整ねじ筒４４内に螺合させたは調整ねじ４５による第１のＸ軸調整部を設け、調整ねじ４５には一端側（上端側）にドライバーなどの回転工具に対する係合手段として例えば六角レンチの係合溝を設け、調整ねじ４５のねじ込みで他端側（下端側）が支圧板３４を圧接可能にしている。
【００３８】
さらに、第２ベース部材４１の第１垂直片４１ａにも溶接その他の固着手段で取付けた調整ねじ筒４６と、調整ねじ筒４６内に螺合させたは調整ねじ４７による第２のＸ軸調整部を設け、調整ねじ４７には一端側（上端側）にドライバーなどの回転工具に対する係合手段として例えば六角レンチの係合溝を設け、調整ねじ４７のねじ込みで他端側（下端側）が支圧板３４を圧接可能にしている。
【００３９】
なお、図７で示すベース部５０Ａのように図６のベース部３０Ａにおける調整ねじ４５，４７に代えて、調整ねじ４８，４９を用いた形態を採ることも可能であり、このベース部５０Ａの場合は調整ねじ４８，４９として例えばスパナなどで回動可能な六角ボルトを用い、調整ねじ筒４４，４６に対する螺合を緩めると一端側（下端側）のねじ頭部が支圧板３４に圧接可能であり、その他の構成は図６の場合と同様である。
【００４０】
ベース部３０Ａ，５０Ａは、支柱部材３２の第２支柱片３２ｂに形成したルーズホールによる遊動取付孔３２ｃと、この遊動取付孔３２ｃに連結ボルト４２を挿通してナット４３を螺合させ、第１ベース部材４０の垂直片４０ｂと第２ベース部材４１の第２垂直片４１ｂを固着連結することによって、支柱部材３２を介してアンカーボルト３３を前後（Ｙ軸）方向に沿った水平位置決めするＹ軸調整部を構成している。
【００４１】
Ｙ軸調整部は、ナット４３の螺合を緩めた状態で支柱部材３２を前後に押し引きし、遊動取付孔に対して連結ボルト４２のねじ軸を予め設定した遊動可能な範囲内で、垂直片４０ｂの撓み変形不能な強軸方向すなわちＹ軸方向に沿って、支柱部材３２を一方側（前方側）ｙ１又は他方側（後方側）ｙ２へ所望に応じて傾斜させた後に、ナット４３を締め付けて固着できるので、アンカー保持部３０Ｂを介して連結したアンカーボルト３３の上端ねじ部３３ａを、設定位置に位置決めして支持することができる。
【００４２】
またベース部３０Ａ，５０Ａは、支柱部材３２の第１支柱片３２ａ側に設けた第１のＸ軸調整部と、第２ベース部材４１の第１垂直片４１ａ側に設けた第２のＸ軸調整部によって、支柱部材３２を介してアンカーボルト３３を左右（Ｘ軸）方向に沿った水平位置決めするＸ軸調整部を構成している。
【００４３】
Ｘ軸調整部は、第１のＸ軸調整部で支柱部材３２を一方側（右側）ｘ１へ、第２のＸ軸調整部で支柱部材３２を他方側（左側）ｘ２へ傾斜させることができるので、アンカー保持部３０Ｂを介して連結したアンカーボルト３３の上端ねじ部３３ａを、所望に位置決めした状態で締結できる。
【００４４】
第１のＸ軸調整部は、ベース部３０Ａの場合には調整ねじ筒４４に対して調整ねじ４５を締め付け、ベース部５０Ａの場合には調整ねじ筒４４に対して調整ねじ４８の締め付けを緩めると、調整ねじ４５，４８の下端側が支圧板３４の上面に圧接しながら支柱部材３２の第１支柱片３２ａを押し上げる。
【００４５】
その際に、第２のＸ軸調整部側の調整ねじ４７，４９の下端側が支圧板３４の上面から離間した状態にしておくと、支柱部材３２の第２支柱片３２ｂが第２ベース部材４１の第２垂直片４１ｂを一方側（右側）ｘ１へ撓み変形させながら、支柱部材３２を一方側（右側）ｘ１へ傾斜させることができる。
【００４６】
第２のＸ軸調整部は、ベース部３０Ａの場合には調整ねじ筒４６に対して調整ねじ４７を締め付け、ベース部５０Ａの場合には調整ねじ筒４６に対して調整ねじ４９の締め付けを緩めると、調整ねじ４７，４９の下端側が支圧板３４の上面に圧接しながら第２ベース部材４１の第１垂直片４１ａを押し上げる。
【００４７】
その際に、第１のＸ軸調整部側の調整ねじ４５，４８の下端側が支圧板３４の上面から離間した状態にしておくと、第２ベース部材４１の第２垂直片４１ｂが第１ベース部材４０の第１垂直片４１ａを他方側（左側）ｘ２へ撓み変形させながら、支柱部材３２を他方側（左側）ｘ２へ傾斜させることができる。
【００４８】
すなわち、水平片４０ａを支圧板３４に固着した第１のベース部材４０の垂直片４０ｂの両側に、Ｌ字状の支柱部材３２と第２のベース部材４１の一方片３２ｂ，４１ｂを装着し、支圧板３４を反力受けにした高さ調整用ねじ手段（図示の実施形態では、調整ねじと調整ねじ筒）で他方片３２ａ，４１ａを押し上げ、第１のベース部材４０の垂直片４０ｂを、撓み変形が可能な弱軸方向すなわちＸ軸方向（ｘ１またはｘ２方向）へ、水平片４０ａとの角度を鈍角状又は鋭角状に傾斜させて支柱部材３２を個別に水平位置決め調整することができる。
【００４９】
このようにして、第１及び第２のＸ軸調整部によってＸ軸調整部の調整作業を行い、各支柱部材３２を介して複数本の各アンカーボルト３３をＸ軸に沿って個別に水平調整することができるので、先行技術３の場合に比べて調整作業を容易且つ高精度に行うことができると共に、１本のアンカーボルト３３を用いた建物の土台などの布基礎に対するアンカーボルトの支持装置にも適用できる。
【００５０】
Ｘ軸調整部は、ねじ軸の先端を押圧面とする図６の実施形態と、ねじ頭部を押圧面とする図７の実施形態では、前者の場合には調整ねじ４５，４７を締め付けたり緩めたりする作業が容易である利点があり、後者の場合には座面が大きくて支圧板３４を安定状態で押圧できる利点がある。
【００５１】
なお、本発明におけるベース部は図示の実施形態に限定されるものではなく、要旨の範囲内において各種の変形を採り得るものであり、例えば図３〜５の実施形態では支柱部材３２に対して、外側へ突出しないようにベース部３０Ａ，５０Ａを内側に配置したが、支柱部材３２の外側にベース部３０Ａ，５０Ａを配置する実施形態を採ることもできる。
【００５２】
また、図示の実施形態では第１支柱片３２ａが左右方向に延在し、第２支柱片３２ｂが前後方向に延在する態様で支柱部材３２を配置したが、支柱部材３２の向きを９０度回転して第１支柱片３２ａが前後方向に延在し、第２支柱片３２ｂが左右方向に延在する態様で配置する形態を採ることも可能であり、この場合には図示に基づく前記した説明のＸ軸方向とＹ軸方向が入れ替わる。
【００５３】
また、図示の実施形態では調整ねじ４５，４７，４８，４９と調整ねじ筒４４，４６で形成した高さ調整用ねじ手段は、同様に機能するたの構造に置換することも可能であり、その一例としては例えば先行技術３の図９に開示されているような実施形態がある。
【００５４】
次に、図８〜１２に基づいて垂直調整部を構成するアンカー保持部について説明すると、図８によるアンカー保持部３０Ｂの場合には、支柱部材３２の上端側に対して基部側を溶接などで固着した平板状の連結部材５１を設け、連結部材５１の上部側には両端部を溶接などで固着した断面Ｖ字状の保持部材５２を設け、内部にアンカーボルト３３を遊嵌状態で挿通する通孔５４を形成すると共に、板面に穿設したねじ孔に押さえねじ５３を螺合して、ねじ軸の先端を保持部材５２の通孔５４内に突出させている。
【００５５】
また、図９によるアンカー保持部６０Ｂの場合には、支柱部材３２の上端側に対して下部側を溶接などで固着した平板状の連結部材６１を設け、連結部材６１の上部側には一辺側を溶接などで固着した三角筒状の保持部材６２を設け、内部にアンカーボルト３３を遊嵌状態で挿通する通孔６４を形成すると共に、残りの二辺のいずれかの一方板面に穿設したねじ孔に押さえねじ６３を螺合して、ねじ軸の先端を保持部材６２の通孔６４内に突出させている。
【００５６】
また、図１０によるアンカー保持部７０Ｂの場合には、支柱部材３２の上端側に対して下部側を溶接などで固着した溝形状の連結部材７１を設け、連結部材７１の上部側には中央の平坦面に溶接などで固着した円筒状の保持部材７２を設け、内部にアンカーボルト３３を遊嵌状態で挿通する通孔７４を形成すると共に、中央の平坦面に穿設したねじ孔に押さえねじ７３を螺合して、ねじ軸の先端を保持部材７２の通孔７４内に突出させている。
【００５７】
また、図１１によるアンカー保持部８０Ｂの場合には、支柱部材３２の上端側に対して下部側を溶接などで固着した溝形状の連結部材８１を設け、連結部材８１の上部側には溶接などで固着したＬ字状の保持部材８２を設け、内部にアンカーボルト３３を遊嵌状態で挿通する通孔８４を形成すると共に、中央の平坦面に穿設したねじ孔に押さえねじ８３を螺合して、ねじ軸の先端を保持部材８２の通孔８４内に突出させている。
【００５８】
また、図１２によるアンカー保持部９０Ｂの場合には、不等辺のアングル材による支柱部材９１の上端側に対して、下部側を溶接などで固着したＬ字状の連結部材兼用の保持部材９２を設け、内部にアンカーボルト３３を遊嵌状態で挿通する通孔９４を形成すると共に、支柱部材９１の一片側に穿設したねじ孔に押さえねじ９３を螺合して、ねじ軸の先端を連結部材兼用の保持部材９２の通孔９４内に突出させている。
【００５９】
これらのアンカー保持部では、保持部材５２，６２，７２，８２，９２の通孔５４，６４，７４，８４，９４内にアンカーボルト３３の下端側を挿通させ、アンカーボルト３３を所望の設定高さ位置に調整して、押さえねじ５３，６３，７３，８４，９４を締め付けると、ねじ軸の先端と保持部材５２，６２，７２，８２，９２の内面の間にアンカーボルト３３が狭持され、支柱部材３２，９１の上端側にアンカーボルト３３を連結することができる。
【００６０】
これらのアンカー保持部によると、図１などで示すアンカー保持部１Ｂのような従来技術とは異なり、支柱部材３２の上端側角隅部にアンカーボルト３３が挿通されておらず、上端側角隅部に十分な空隙部５５，６５，７５を確保することができるので、アンカーボルトの支持装置を基礎コンクリート中に埋設した際に、コンクリート中に混合した粒径の大きな粗骨材も十分に充填されて強固な支持力が得られる。
【００６１】

Japanese Patent No. 27894952
[Patent Document 2]
JP 2003-3486 A
[0004]
FIG. 1 shows an embodiment of an anchor bolt support device 1 proposed in Patent Document 2, and includes a base portion 1A provided on abandoned concrete of a foundation ground 2, and a column member 3 erected from the base portion 1A. The anchor holding portion 1B provided on the upper end side of the column member 3, the anchor bolt 4 connected to the column member 3 via the anchor holding portion 1B, and the template portion 1C provided on the upper end side of the anchor bolt 4 are configured. ing.
[0005]
1 A of base parts are equipped with a pair of 1st base members 5 and 5 arranged in parallel with right and left, and a pair of 2nd base members 6 and 6 arranged in parallel back and forth, and the 1st base member 5 is L-shaped. The horizontal piece 5a is fixed on the foundation ground 2 with the wall anchor 7 and the nut 8, and the lower end side of the column member 3 is fixed with the bolt 9 and the nut 10 to the vertical piece 5b. Between the two, the second base members 6 and 6 are installed, and both ends are fixedly connected with bolts 11 and nuts 12.
[0006]
The anchor holding portion 1B is configured such that a square holding member 14 is fixed to the L-shaped column member 3 with a bolt 13, and the anchor bolt 4 is inserted into the holding member 14 to set a desired height position. The anchor bolt 4 is fastened to the support member 3 by tightening the connection bolt 15 screwed to the support member 3, and in particular, the anchor bolt 4 is pressed away from the corner of the support member 3, and the corner of the support member 3 is pressed. A space is provided between the anchor bolt 4 and the anchor bolt 4 so that the coarse aggregate of concrete to be cast can be filled.
[0007]
In the template portion 1C, the four templates 16 are combined in a rectangular shape so as to be orthogonal to each other, and the upper end screw portion 4a of the anchor bolt 4 is inserted into the corner portion of the template 16 and screwed into the upper end screw portion 4a. The template 16 is clamped by a pair of upper and lower nuts 17, whereby the mutual interval between the anchor bolts 4 is defined.
[0008]
In such an anchor bolt support device, the height position of the upper end screw portion 4a of the anchor bolt 4 in the template portion 1C is anchor-held in order to make the center of the support device exactly coincide with the center of the mounting position of the pillar or base. Positioned in the vertical (Z-axis) direction by adjusting the portion 1B, and the front and rear and left and right positions of the upper end screw portion 4a via the support member 3 are adjusted by the base portion 1A to be in the horizontal (X-axis, Y-axis) direction. Need to be positioned.
[0009]
However, in the case of the anchor bolt support device 1 in the prior art such as Patent Documents 1 and 2, the vertical position of the upper end screw portion 4a is adjusted by the anchor holding portion 1B for positioning in the vertical (Z-axis) direction. Although easy, the left and right and front and back positions of the upper end screw portion 4a are adjusted by the base portion 1A and positioned in the horizontal (X-axis, Y-axis) direction, which is not necessarily a sufficient structure.
[0010]
That is, the base members 5 and 6 that support the lower end side of each column member 3 are integrated in a rectangular frame shape, and the influence of the unevenness of the upper surface of the discarded concrete placed on the foundation ground 2 is affected by the entire base portion 1A. Therefore, it is necessary to perform positioning adjustment in the horizontal (X axis, Y axis) direction for all the column members 3 and position each column member 3 individually by mutual interference of the base members 5 and 6. It was difficult to make adjustments.
[0011]
Accordingly, the applicant of the present application has previously proposed a patent application that enables easy positioning adjustment in the horizontal (X-axis, Y-axis) direction. Japanese Patent Application No. 2002-111642 (prior art 1) and Japanese Patent Application No. 2002-212417. (Prior art 2) In the case of these prior arts 1 and 2, when the horizontal positioning adjustment is performed, a pulling force acts on the wall anchor, and the base member is discarded from the foundation ground. There was a risk of lowering the supporting force away from the concrete top surface.
[0012]
Therefore, it is possible to easily perform positioning adjustment in the horizontal (X-axis, Y-axis) direction as in the prior arts 1 and 2 or more, and the wall anchor which is a problem of the prior arts 1 and 2 The present applicant has previously proposed Japanese Patent Application No. 2002-317123 (prior art) which can prevent the lowering of the supporting force by preventing the pulling force from acting on the base member and separating the base member from the foundation ground. 3).
[0013]
FIG. 2 shows a base portion 20A in an anchor bolt support device according to Prior Art 3. The base member 21 has an L-shaped cross section formed by a horizontal piece 21a and a vertical piece 21b, and the horizontal piece 21a is in the foundation ground. The vertical anchor 21b is connected to the lower end of the column member 25 via a bolt 24 and a nut (not shown).
[0014]
The column member 25 has an L-shaped cross section formed by a first column piece 25a along the X direction and a second column piece 25b along the Y direction, and the second column piece 25b (in the illustrated embodiment, The first support piece 25a is also provided with a loose mounting hole 26 in which the screw shaft of the bolt 24 is loosely fitted, and the adjusting screw cylinder 27 is welded to the first support piece 25a. The adjustment screw 28 is screwed together.
[0015]
The base portion 20A changes the screwing state of the adjusting screw 28 with respect to the adjusting screw cylinder 27, presses the screw head against the upper surface of the horizontal piece 21a to form a supporting plate, and pushes up the first support piece 25a. Since the vertical piece 21b is bent and deformed in one direction x1 in the X direction via the two post pieces 25b, and thereby the post member 25 can be held in a desired inclined state, the upper end of the anchor bolt connected to the upper end side of the post member 25 The horizontal position of the thread portion can be adjusted in the X direction.
[0016]
Further, when the strut member 25 is pressed in one direction y1 or the other direction y2 in the Y direction while the nut screwed into the bolt 24 is loosened, the screw shaft of the bolt 24 is loosely moved in the loose mounting hole 26 by the loose hole. When the nut is retightened, the column member 25 can be held in a desired inclined state, so that the horizontal position of the upper end thread portion of the anchor bolt connected to the upper end side of the column member 25 can be adjusted in the y direction.
[0017]
In the case of this base portion 20A, when the column member 25 is positioned and adjusted in the other direction x2 in the X direction, a base portion having a similar configuration is provided at a position opposite to the base portion 20A, and the adjustment screw cylinder of this base portion is provided. On the other hand, by adjusting the screwing state of the adjusting screw and inclining the column member at the opposite position in the other direction x2, the column member 25 on the base portion 20A side and the vertical piece 21b are positioned and adjusted via the template portion. To do.
[0018]
In this way, each anchor bolt is mounted on the upper end side of each of the plurality of support members via the anchor holding portion capable of positioning adjustment in the vertical (Z-axis) direction, and the base on which each support member is erected If the horizontal positioning adjustment part that positions along the X-axis and Y-axis is provided in the part, it becomes possible to adjust each strut member individually in the XYZ direction, and the upper end screw part of each anchor bolt is attached to the column The position can be matched exactly.
[0019]
[Problems to be solved by the invention]
However, there is still room for improvement in the anchor bolt support device according to the improved prior art 3. For example, in positioning adjustment along the X-axis direction, the x2 direction or the x1 direction (the state of FIG. 2 is rotated 180 degrees). When adjusting either one of the two), it is not easy to make individual adjustments in the state where there is no mutual interference with the base at the opposite position. Thus, when using with one anchor bolt, it will be adjusted only in one direction.
[0020]
Further, in the configuration of the anchor holding portion, as shown in FIG. 1, when the anchor bolt is pressed with a connecting bolt in a direction away from the corner portion of the support member, and a gap is provided between the corner portion of the support member and the anchor bolt, Although it is improved so that the coarse aggregate of the concrete to be placed can be filled, it is desirable to further improve this so that the coarse aggregate of the concrete to be placed can be filled more with respect to the upper end side corner portion of the support member. .
[0021]
Accordingly, the present invention provides an anchor bolt support device that can solve these problems, and when performing horizontal positioning adjustment with respect to the anchor bolt, a pulling force acts on the wall anchor, or the base member is a foundation. It is possible to prevent the lowering of the supporting force by eliminating the separation from the ground, reduce the mutual interference between the X axis direction and the Y axis direction in the horizontal positioning adjustment, and easily and quickly perform the horizontal positioning adjustment independently for each anchor bolt. The first object is to make it possible to apply to cloth foundations in addition to independent foundations.
[0022]
In addition, the connecting structure in the anchor holding part that connects the anchor bolt to the support member so that the height can be adjusted along the Z-axis direction has been improved, and the concrete coarse aggregate placed on the support member has an upper side corner. The second object is to increase the adhesion force of the concrete to the anchor bolt and the column member and to enhance the support force to the ground so that the portion can be filled more.
[0023]
