【０００１】
【発明の属する技術分野】
本発明は、水平基準を形成するための水準形成装置、水準形成システム、および特にコンクリート基礎を形成するために有用であるコンクリート基礎の形成方法に関する。
【０００２】
【背景技術】
従来、建造物としての木造家屋を建築する際、まず木造家屋を安定に支持するためのコンクリート基礎を構築する。このコンクリート基礎を構築する際、所定の地所内の木造家屋を建築する領域を囲むように、水平の基準となる柵状基準構築物、いわゆる遣方を構築する。
【０００３】
この遣方は、木造家屋を建築する領域を示すいわゆる地縄を囲むように、所定間隔で角材や木杭である水杭を地面に打設する。そして、トランシット（transit）を用いて、各水杭に同一水平位置となる印を付ける。この印の位置が所定の幅寸法の巾木である水貫の長手方向の一側を位置合わせし、各水杭を水貫にて連結して地縄を囲むように水貫を水貫に釘止めして遣方を形成している。
【０００４】
この遣方の水貫の縁にて形成される平面は、水平面となる。このことにより、地縄内でコンクリート基礎を形成するために溝状に掘削、すなわち根切りを実施する場合、水貫の長手方向の一縁である上縁に適宜水糸を張設する。そして、所定の長さ寸法の印が設けられた材木や所定の長さ寸法に切断した材木を用い、水糸からの深さを確認しつつ所定の深さに掘削し、水糸を基準に所定の高さ寸法のコンクリート基礎を形成する。このことにより、上端が水平なコンクリート基礎が得られる。
【０００５】
【発明が解決しようとする課題】
【０００６】
しかしながら、従来のコンクリート基礎の形成では、遣方を設けて水糸を張設し、深さを確認しつつ根切り作業することとなり、水糸が根切り作業の邪魔となり、根切り作業が煩雑で、効率よくコンクリート基礎を形成できない。また、遣方に用いる水貫は、水平の基準となる長手方向の縁が略直線となる材木を用いる必要があり、遣方の形成も煩雑となる問題がある。
【０００７】
本発明は、上記問題点に鑑みて、簡単な構成で容易に水平基準を形成できる水準形成装置、水準形成システム、および容易に水平基準が形成されコンクリート基礎の形成方法を提供することを目的とする。
【０００８】

【００４４】
【発明の実施の形態】
以下、本発明の一実施の形態の水準形成システムの構成を図面に基づいて説明する。
【００４５】
〔水準形成システムの構成〕
図１において、１は水準形成システムで、この水準形成システム１は、建造物としての例えば図示しない木造家屋を建築するために木造家屋を安定して支持するための図示しないコンクリート基礎の形成に用いる。そして、水準形成システム１は、両腕水準形成装置２と片腕水準形成装置３とを備え、これら両腕水準形成装置２および片腕水準形成装置３の組み合わせにて構成される。すなわち、水準形成システム１は、形成するコンクリート基礎の平面形状に対応して、両腕水準形成装置２および片腕水準形成装置３のうちの少なくとも両腕水準形成装置２を含む少なくとも一対以上の組み合わせで、複数の両腕水準形成装置２および片腕水準形成装置３にて構成される。
【００４６】
また、両腕水準形成装置２および片腕水準形成装置３には、それぞれアタッチメント部としてのブロック積み用アタッチメント５および傾斜アタッチメント６が着脱可能に取り付けられ、水準形成システムとしての変則水準形成装置７，８を構成する。
【００４７】
（両腕水準形成装置）
そして、両腕水準形成装置２は、図２および図３に示すように、支柱部１１と、両腕部１２と、水糸取付部１３とを備えている。
【００４８】
支柱部１１は、杭部１５とを有している。なお、支柱部１１は、十分な高さ寸法が得られない場合、図４に示すように、継部１６を杭部１５に一体的に連結した構成としてもよい。
【００４９】
杭部１５は、図２および図３に示すように、例えば鋼材にて四角棒状に形成されている。この杭部１５の長手方向の一端には、先端に向けて次第に径小となる先細り部１７が設けられている。この先細り部１７が地面に打ち込まれ、杭部１５は先細り部１７と反対側の端部が地面から上方に向けて突出する状態に地面に立設される。
【００５０】
杭部１５の中間には、例えば鋼管にて略四角筒状に形成された一対の筋交い取付部１８が溶接などにより一体的に取り付けられている。これら筋交い取付部１８は、軸方向が杭部１５の長手方向である軸方向に対して交差し、杭部１５の異なる面に互いに軸方向が交差する状態で、杭部１５の端部から異なる距離の位置に段違い状に設けられる。
【００５１】
これら筋交い取付部１８の外周面には、ナット１９が溶接にて一体的に取り付けられている。このナット１９は、内周面に設けられた図示しない雌ねじが筋交い取付部１８の内周面に連続する状態に取り付けられる。そして、このナット１９には、操作ねじ２０が取り付けられている。この操作ねじ２０は、雄ねじ部２０ａと、この雄ねじ部２０ａの軸方向の一端に設けられ把持される操作部２０ｂとを有している。そして、操作ねじ２０は、雄ねじ部２０ａを回転軸とした操作部２０ｂの回転操作により、雄ねじ部２０ａの先端が筋交い取付部１８の内周面から内方に向けて進退可能に筋交い取付部１８に取り付けられる。
【００５２】
そして、筋交い取付部１８には、操作ねじ２０により例えば鉄筋棒などの細長棒状の筋交い部材２１が取り付けられる。この筋交い部材２１は、筋交い取付部１８に嵌挿され、操作ねじ２０のねじ込み操作により雄ねじ部２０ａの先端で筋交い取付部１８の内周面に押し付けられ、筋交い取付部１８に位置決め固定される。このことにより、杭部１５が安定して地面に立設される。
【００５３】
一方、杭部１５に連結する継部１６は、図４に示すように、例えば鋼材にて形成され、四角筒状の嵌挿連結部２５と、この嵌挿連結部２５に同軸上に設けられた四角柱状の延長部２６とを有している。嵌挿連結部２５は、杭部１５の端部側である先細り部１７とは反対側を嵌挿可能に四角筒状に形成されている。また、延長部２６は、杭部１５と略同寸法の四角柱状に形成されている。そして、延長部２６は、嵌挿連結部２５の軸方向の一端に、この嵌挿連結部２５に対して略同軸上に溶接などにより一体的に設けられている。
【００５４】
さらに、嵌挿連結部２５の外周面には、杭部１５の筋交い取付部１８に設けられたものと同様のナット１９が、嵌挿連結部２５の軸方向に沿って複数併設、例えば２つ設けられている。そして、これらナット１９には、杭部１５の筋交い取付部１８に設けられたものと同様の操作ねじ２０がそれぞれ設けられている。これら操作ねじ２０は、雄ねじ部２０ａを回転軸とした操作部２０ｂの回転操作により、雄ねじ部２０ａの先端が嵌挿連結部２５の内周面から内方に向けて進退可能に取り付けられる。
【００５５】
そして、支柱部１１は、継部１６の嵌挿連結部２５に杭部１５の他端側が嵌挿され、操作ねじ２０のねじ込みにより杭部１５と継部１６とが一体的に連結されて構成される。
【００５６】
なお、杭部１５は、例えば図５に示す構成の杭打ち治具２７により地面に打ち込まれる。すなわち、杭打ち治具２７は、例えば鋼材にて形成され、嵌挿保持部２８と打ち込み部２９とを有し、継部１６と同様に形成されている。すなわち、嵌挿保持部２８は、杭部１５の他端側である先細り部１７とは反対側を嵌挿可能に四角筒状に形成されている。また、打ち込み部２９は、嵌挿保持部２８の一端にこの嵌挿保持部２８に対して略同軸上に溶接などにより一体的に設けられている。そして、嵌挿保持部２８に杭部１５の他端側を嵌挿し、打ち込み部２９を図示しない木槌などにて打ち込むことにより杭部１５を地面に立設する。このことにより、杭部１５の端部が打撃による潰れなどの変形を防止できる。
【００５７】
一方、両腕部１２は、例えば鋼管にて略四角筒状に形成された胴体部３１を有している。この胴体部３１は、支柱部１１の杭部１５や継部１６の延長部２６を嵌挿可能に形成されている。また、胴体部３１の外周面には、支柱部１１の継部１６と同様にナット１９が複数、例えば２つのナット１９が胴体部３１の軸方向に沿って併設されている。そして、これらナット１９には、支柱部１１と同様に操作ねじ２０がそれぞれ設けられている。これら操作ねじ２０は、雄ねじ部２０ａを回転軸とした操作部２０ｂの回転操作により、雄ねじ部２０ａの先端が胴体部３１の内周面から内方に向けて進退可能に取り付けられる。
【００５８】
胴体部３１の外周面には、例えば鋼管にて略四角筒状に形成された第１腕部３２ａが設けられている。この第１腕部３２ａは、軸方向が胴体部３１の外面に略垂直に交差する状態に溶接などにより一体的に取り付けられている。
【００５９】
また、胴体部３１の外周面には、例えば鋼管にて略四角筒状に形成された腕保持部３３が設けられている。この腕保持部３３は、第１腕部３２ａが設けられた面に隣接する面に設けられ、第１腕部３２ａより短い寸法に形成されている。この腕保持部３３は、軸方向が胴体部３１の外面に略垂直に交差するとともに、第１腕部３２ａに対して軸方向が互いに略直交する状態に取り付けられている。そして、腕保持部３３の先端部分と第１腕部３２ａの基端部分との間には、これら第１腕部３２ａおよび腕保持部３３とにて直角三角形を構成するように補強板３４が溶接などにより一体的に取り付けられている。
【００６０】
さらに、腕保持部３３には、上述したものと同様のナット１９および操作ねじ２０が設けられている。この操作ねじ２０も、雄ねじ部２０ａを回転軸とした操作部２０ｂの回転操作により、雄ねじ部２０ａの先端が腕保持部３３の内周面から内方に向けて進退可能に取り付けられる。
【００６１】
腕保持部３３には、着脱可能に連結腕部３５が設けられている。この連結腕部３５は、例えば鋼材にて四角筒状に形成されている。また、連結腕部３５の軸方向の一端には、腕保持部３３に嵌挿可能な棒状の連結部３６が略同軸上に設けられている。そして、連結腕部３５の連結部３６が腕保持部３３に嵌挿され、腕保持部３３の操作ねじ２０の締め付けにより、腕保持部３３に連結腕部３５が一体的に取り付けられ、第２腕部３２ｂが構成される。なお、操作ねじ２０の締め込みにより、突出する操作ねじ２０の雄ねじ部２０ａの先端にて連結腕部３５が腕保持部３３の内周面に押し付けられ、一体的に連結される。
【００６２】
なお、第１腕部３２ａおよび第２腕部３２ｂの腕保持部３３には、図示しない水準器が設けられている。なお、水準器は、例えば磁力にて着脱可能に取り付けられる構成としたり、設けなくてもよく、また連結腕部３５や支柱部１１に設けてもよい。
【００６３】
また、水糸取付部１３は、摺動部３７と糸取付板３８とを備えている。摺動部３７は、例えば鋼管にて四角筒状で、内周に第１腕部３２ａや第２腕部３２ｂの連結腕部３５を嵌挿可能な四角筒状に形成されている。また、この摺動部３７には、上述したナット１９および操作ねじ２０と同一のものが設けられている。そして、摺動部３７は、操作ねじ２０の回転操作により雄ねじ部２０ａの先端が摺動部３７の内周面から突出して第１腕部３２ａや第２腕部３２ｂの連結腕部３５に当接し、第１腕部３２ａや第２腕部３２ｂの連結腕部３５に対して相対的な摺動が規制される。
【００６４】
また、糸取付板３８は、例えば鋼板にて長方形平板状に形成されている。この糸取付板３８は、長手方向の一縁が摺動部３７の軸方向の一端一縁に連続し、平面が第１腕部３２ａや第２腕部３２ｂの連結腕部３５の軸方向に対して略直交する状態に溶接などにより一体的に取り付けられている。さらに、糸取付板３８には、略所定間隔で複数、例えば３つの取付孔３９が穿設されている。これら取付孔３９は、例えば釘などが嵌挿可能に設けられている。
【００６５】
（片腕水準形成装置）
片腕水準形成装置３は、図６および図７に示すように、上述した両腕水準形成装置２と同様の支柱部１１と、片腕部４１と、水糸取付部４２とを備えている。なお、支柱部１１は、両腕水準形成装置２と同一の構成であり、説明は省略する。また、図８に示すように、継部１６を杭部１５に連結して支柱部１１としてもよい。すなわち、両腕水準形成装置２と片腕水準形成装置３とは、支柱部１１を共用できる。
【００６６】
片腕部４１は、両腕水準形成装置２の両腕部１２と同様に、例えば鋼管にて略四角筒状に形成された胴体部３１を有している。この胴体部３１は、支柱部１１の杭部１５や継部１６の延長部２６を嵌挿可能に形成されている。
【００６７】
そして、胴体部３１の外周面には、伸縮腕保持部４３が設けられている。この伸縮腕保持部４３は、例えば鋼管にて略四角筒状に形成されている。また、伸縮腕保持部４３には、一面の略中央に軸方向に沿った切り溝４４が設けられている。そして、伸縮腕保持部４３は、軸方向が胴体部３１の軸方向に対して略直交する十文字状に溶接などにより一体的に取り付けられている。さらに、伸縮腕保持部４３には、例えば軸方向の両端部に位置して、上述したナット１９および操作ねじ２０と同様のものが一対設けられている。これら操作ねじ２０も、回転操作により雄ねじ部２０ａの先端が伸縮腕保持部４３の内周面から進退可能に取り付けられている。
【００６８】
伸縮腕保持部４３には、着脱可能に両腕水準形成装置２の水糸取付部１３に対応する伸縮連結腕部４５が設けられている。この伸縮連結腕部４５は、例えば鋼板にて四角筒状で、伸縮腕保持部４３の内周に嵌挿可能な形状に形成されている。そして、この伸縮連結腕部４５が伸縮腕保持部４３に摺動可能に嵌挿され、操作ねじ２０の締め込みにより伸縮連結腕部４５の摺動が規制可能に組み付けられて腕部４６が構成されている。
【００６９】
また、伸縮連結腕部４５には、軸方向の一端側外周面に、両腕水準形成装置２と同様の取付孔３９を有した平板状の糸取付板３８が設けられている。この糸取付板３８は、平面が伸縮連結腕部４５の軸方向に沿う状態で溶接などにより一体的に取り付けられている。そして、糸取付板３８は、伸縮連結腕部４５の伸縮腕保持部４３に対する摺動により、伸縮腕保持部４３の切り溝４４に摺動可能に係合し、糸取付板３８が伸縮腕保持部４３に対して移動される。すなわち、伸縮腕保持部４３に摺動する伸縮連結腕部４５とにて水糸取付部４２を構成する。
【００７０】
そして、伸縮腕保持部４３には、図示しない水準器が設けられている。なお、水準器は、例えば磁力にて着脱可能に取り付けたる構成としたり、設けなくてもよく、また伸縮連結腕部４５や支柱部１１に設けてもよい。
【００７１】

連結支柱部５１は、伸縮支柱部５５と、伸縮連結支柱部５６と、伸縮連結杭部５７とを備えている。
【００７３】
伸縮支柱部５５は、上述した片腕水準形成装置３の伸縮腕保持部４３と略同形状、すなわち切り溝４４を有した四角筒状に形成されている。そして、この伸縮支柱部５５には、上述したナット１９および操作ねじ２０と同様のものが両端部および中間部に設けられている。
【００７４】
伸縮連結支柱部５６は、片腕水準形成装置３の伸縮連結腕部４５と同様に、伸縮支柱部５５に摺動可能な四角柱状に形成されている。そして、この伸縮連結支柱部５６の軸方向の一端部には、片腕水準形成装置３と同様に、取付孔３９を有した糸取付板３８が設けられている。この伸縮連結支柱部５６は、糸取付板３８が下端側および上端側のいずれ側となる状態でも伸縮支柱部５５に嵌挿保持可能となっている。なお、糸取付板３８は、伸縮支柱部５５の切り溝４４を挿通可能に切り込み５８が設けられている。
【００７５】
伸縮連結杭部５７は、上述した杭部１５と同様に一端が先細り状に形成された四角棒状に形成され、伸縮支柱部５５に嵌挿して連結される。
【００７６】
なお、伸縮支柱部５５および伸縮連結杭部５７は、一体に形成した構成としてもできる。例えば伸縮支柱部５５を四角棒状に形成して一端側を杭状に縮径して一体形成したり、伸縮支柱部５５に伸縮連結杭部５７を溶接などにて接合するなどしてもできる。また、伸縮支柱部５５を四角柱状に形成した場合、伸縮連結支柱部５６は、例えば両腕水準形成装置２の摺動部３７のように伸縮支柱部５５を移動可能に嵌挿する四角筒状や切り溝４４を有する筒形状とすることもできる。
【００７７】
さらに、伸縮支柱部５５を柱状に形成し、伸縮連結支柱部５６を筒形状とする場合には、伸縮連結支柱部５６が後述するアタッチメント腕部５２に当接しない構成とすることが好ましい。例えば、伸縮支柱部５５の両側面に軸方向に沿って凹溝や凸状のガイド部を設ける。また、伸縮連結支柱部５６を断面略コ字状に形成するとともに、開口縁部にガイド部に摺動可能に係合する係合案内部を設ける構成とするなどが好ましい。
【００７８】
そして、この連結支柱部５１の伸縮支柱部５５の中間部には、操作ねじ２０が取り付けられる面にアタッチメント腕部５２が一体に設けられている。このアタッチメント腕部５２は、例えば図９に示すように、片腕水準形成装置３の伸縮連結腕部４５と同形状、すなわち腕部である伸縮腕保持部４３に嵌挿可能な四角柱状に形成されている。
【００７９】
なお、アタッチメント腕部５２は、四角柱状に限らず、例えば両腕水準形成装置２の摺動部３７と同様に、ナット１９および操作ねじ２０を備えた四角筒状や切り溝４４を有した筒形状に形成したものなどでもできる。この構成とすることにより、両腕水準形成装置２にも取り付けられる構成が得られる。
【００８０】
（傾斜アタッチメント）
アタッチメント部としての傾斜アタッチメント６は、図１１に示すように、傾斜支柱部６１と、回動連結腕部６２とを備えている。
【００８１】
傾斜支柱部６１は、ブロック積み用アタッチメント５と同様の伸縮支柱部５５と、伸縮杭部６５とを備えている。伸縮杭部６５は、上述した杭部１５と同様に一端が先細り状に形成された四角棒状に形成され、伸縮支柱部５５に嵌挿して連結される。さらに、伸縮杭部６５には、軸方向が交差する方向に略四角筒状の筋交い取付部１８が溶接などにより一体的に取り付けられている。なお、傾斜支柱部６１は、ブロック積み用アタッチメント５と同様に、伸縮支柱部５５および伸縮杭部６５とを一体に形成した構成とすることもできる。
【００８２】
傾斜支柱部６１の伸縮杭部６５が取り付けられる側と反対側には、回動連結腕部６２が回動可能に設けられている。この回動連結腕部６２は、例えば片腕水準形成装置３の伸縮連結腕部４５と同形状、すなわち腕部である伸縮腕保持部４３に嵌挿可能な四角柱状に形成されている。
【００８３】
〔水準形成システムの動作〕
次に、上記水準形成システム１の動作について、コンクリート基礎を形成する動作を例示して図面に基づいて説明する。
【００８４】
（水準形成システム）
図１に示すように、まず図示しない木造家屋を建築する所定の地所７１内に、基準点７２から木造家屋が建築される領域を囲む地縄７３を形成する。例えば、図面に表示される地縄７３の角部分を、基準点７２を結ぶ直線上で基準点７２から図面中の寸法の距離となる位置を地面に記す。この位置から、基準点７２を結ぶ直線に対する垂線上で図面中の寸法の距離となる位置を、地縄７３の角部分として地面に記す。このようにして記した各地縄７３の角部分を直線で結んで囲まれた地縄７３を地面に形成する。なお、地面への印は、例えば鉄筋棒や木杭の一部を地面に埋めて立設し、これら鉄筋棒や木杭間に白線を形成して地縄７３を形成する。
【００８５】
そして、この地縄７３から所定距離、例えば１〜２ｍ程度離れた位置に両腕水準形成装置２や片腕水準形成装置３を配設する。すなわち、図１に示すように、地縄７３の角近傍には両腕水準形成装置２が配設される。また、地縄７３の辺の位置で反対側に両腕水準形成装置２が設置される位置には片腕水準形成装置３が配設される。
【００８６】
これら両腕水準形成装置２および片腕水準形成装置３は、まず杭部１５の先細り部１７を目測にて地縄７３から例えば１〜２ｍ離れた位置に突き刺す。そして、図５に示すように、突き刺した杭部１５の上端側となる先細り部１７と反対側の端部に杭打ち治具２７の嵌挿保持部２８を取り付け、杭部１５に杭打ち治具２７を取り付ける。杭部１５に取り付けた杭打ち治具２７の打ち込み部の端部を木槌などにて叩き、杭部１５を地面に立設する。
【００８７】
なお、この杭部１５の打ち込みの際、地縄７３の角近傍に立設される両腕水準形成装置２のための杭部１５は、筋交い取付部１８が地縄７３が設けられている領域と反対側となる外側に位置し、かつ筋交い取付部１８が設けられた杭部１５の面が地縄７３の辺に略沿う状態とする。また、地縄７３の辺近傍に立設される片腕水準形成装置３のための杭部１５は、一方の筋交い取付部１８が地縄７３と反対側となる外側に位置し、他方の筋交い取付部１８の下端が地縄７３と反対側の外側に向けて傾斜する状態とする。
【００８８】
所定位置に杭部１５を立設した後、地面が傾斜しており各杭部１５の地面から突出する上端の位置が水平面において大きく、例えば１〜２ｍ程度異なる場合には、低い位置となる杭部１５に継部１６を連結する。すなわち、杭部１５の上端部が継部１６の嵌挿連結部２５に嵌挿する状態に杭部１５に継部１６を取り付ける。この状態で、杭部１５の操作ねじ２０を締め込んで継部１６を杭部１５に一体的に組み付け、支柱部１１を組立形成する。なお、継部１６が取り付けられない高い位置の杭部１５は、杭部１５自体を支柱部１１とする。
【００８９】
そして、杭部１５および支柱部１１の継部１６に両腕部１２あるいは片腕部４１を組み付ける。なお、地縄７３の角近傍に配設された杭部１５あるいは支柱部１１には両腕部１２が組み付けられ、地縄７３の辺近傍に配設された杭部１５あるいは支柱部１１には片腕部４１が組み付けられる。すなわち、両腕部１２あるいは片腕部４１の胴体部３１に杭部１５および継部１６の延長部２６を嵌挿させ、両腕部１２あるいは片腕部４１が地面から所定の位置、例えば１ｍ程度の高さの位置で両腕部１２あるい片腕部４１の各操作ねじ２０を締め込み、杭部１５および支柱部１１の継部１６に両腕部１２あるいは片腕部４１を一体的に組み付ける。
【００９０】
さらに、両腕部１２には、この両腕部１２の腕保持部３３に連結腕部３５の連結部３６を嵌挿し、腕保持部３３の操作ねじ２０を締め込む。このことにより、腕保持部３３に連結腕部３５が一体的に組み付けられ、両腕部１２に２本の第１腕部３２ａおよび第２腕部３２ｂが略直角方向に延出する状態に組立形成される。
【００９１】
この後、杭部１５に設けられた筋交い取付部１８に、例えば鉄筋棒などの細長棒状の筋交い部材２１を嵌挿し、筋交い部材２１の端部を地面に打ち込む。そして、両腕部１２および片腕部４１に設けられた水準器を確認しつつ、杭部１５の軸方向が略鉛直方向に沿うようにし、筋交い取付部１８の操作ねじ２０を締め込む。このことにより、杭部１５は軸方向が略鉛直方向に沿う状態が維持されて地面に立設される。
【００９２】
なお、地縄７３の角近傍に立設される杭部１５の筋交い取付部１８が地縄７３が設けられている領域と反対側となる外側に位置し、かつ筋交い取付部１８が設けられた杭部１５の面が地縄７３の辺に略沿う状態に杭部１５が地面に立設されている。このことにより、地縄７３の角近傍の杭部１５に取り付けられた筋交い部材２１は、第１腕部３２ａおよび第２腕部３２ｂが延出する方向に沿って杭部１５から地面に向けて斜めに打ち込まれた状態となり、設置領域が最小限となる。
【００９３】
また、地縄７３の辺近傍に立設される杭部１５の一方の筋交い取付部１８が地縄７３が設けられている領域と反対側となる外側に位置し、他方の筋交い取付部１８の下端が外側に向けて傾斜する状態に杭部１５が地面に立設されている。このことにより、地縄７３の辺近傍の杭部１５に取り付けられた一方の筋交い部材２１は腕部４６が延出する方向に沿って杭部１５から地面に向けて斜めに打ち込まれ状態となり、設置領域が縮小できる。また、他方の筋交い部材２１は、地縄７３が設けられている領域と反対側の地面に向けて斜めに打ち込まれる。このため、筋交い部材２１が後述する根切り作業の際に掘り返されることが防止され、支柱部１１が確実に安定して立設される。
【００９４】
次に、両腕部１２に設けられた第１腕部３２ａおよび第２腕部３２ｂには、水糸取付部１３を取り付ける。また、片腕部４１の伸縮腕保持部４３には、伸縮連結腕部４５を取り付ける。
【００９５】
すなわち、水糸取付部１３は、摺動部３７に両腕部１２の各第１腕部３２ａおよび第２腕部３２ｂがそれぞれ嵌挿する状態に、各第１腕部３２ａおよび第２腕部３２ｂにそれぞれ取り付ける。そして、目測で糸取付板３８が地縄７３の辺の延長線上に位置するように、水糸取付部１３を各第１腕部３２ａおよび第２腕部３２ｂに対して摺動させる。この後、操作ねじ２０を締め付けて各第１腕部３２ａおよび第２腕部３２ｂの所定の位置に位置決め固定する。
【００９６】
同様に、片腕部４１の伸縮腕保持部４３に伸縮連結腕部４５を嵌挿する。そして、目測により伸縮連結腕部４５の糸取付板３８が地縄７３の辺の延長線上に位置するように、伸縮連結腕部４５を伸縮腕保持部４３に対して摺動させ、操作ねじ２０を締め付けて伸縮連結腕部４５を固定し腕部４６を組立形成する。
【００９７】
このようにして、両腕水準形成装置２および片腕水準形成装置３を所定の位置に組立形成し、水準形成システム１を構築する。なお、杭部１５および継部１６に両腕部１２および片腕部４１を取り付けた後に第２腕部３２ｂおよび腕部４６を組立形成したが、あらかじめ第２腕部３２ｂを組立形成した両腕部１２、あるいは第２腕部３２ｂおよび水糸取付部１３を取り付けた両腕部１２、および腕部４６を組立形成した片腕部４１を杭部１５および継部１６に取り付けてもよい。
【００９８】
そして、図示しないトランシット（transit）を用いて、各両腕水準形成装置２および片腕水準形成装置３の糸取付板３８が略同一水平面上に位置するように、両腕部１２および片腕部４１の支柱部１１に対する位置を可変設定する。すなわち、両腕部１２および片腕部４１の各操作ねじ２０を緩めて、支柱部１１に対して両腕部１２および片腕部４１を移動可能とする。そして、トランシットの望遠鏡の視野内に糸取付板３８が確認される位置で、操作ねじ２０を再び締め付け、両腕部１２および片腕部４１を支柱部１１に位置決め固定する。この後、各糸取付板３８にトランシットの望遠鏡のメモリ位置に対応する位置に印を設ける。なお、トランシットの代わりにレーザ光を用いた自動水準器を用いてレーザ光が当たる水平位置にそれぞれ印を設けてもよい。
【００９９】
さらに、図３および図７に示すように、糸取付板３８の印の位置で水糸７５を糸取付板３８に取り付け、地縄７３の辺の延長線上に位置する糸取付板３８間に水糸７５を張設する。この水糸７５の糸取付板３８への取り付けは、水糸７５を糸取付板３８に巻き付けて糸取付板３８に設けた印の位置で水糸７５が張設されるようにしたり、水糸７５の端部を環状に結んで形成した環状部を糸取付板３８に引っ掛けたり、水糸７５の端部に取り付けた釘などを糸取付板３８の取付孔３９に係止して取り付ける。
【０１００】
また、水糸７５を張設する際、水糸７５が地縄７３の略鉛直方向の上方に地縄７３に対して略平行とならない場合には、両腕水準形成装置２の水糸取付部１３あるいは片腕水準形成装置３の伸縮連結腕部４５を移動させる。すなわち、両腕水準形成装置２の水糸取付部１３を移動する場合には、水糸取付部１３に設けられた操作ねじ２０を緩め、水糸７５が地縄７３の上方において略平行となるように水糸取付部１３を摺動させ、再び操作ねじ２０を締め付けて水糸取付部１３を位置決め固定する。また、片腕水準形成装置３の場合、伸縮腕保持部４３に設けられた操作ねじ２０を緩め、水糸７５が地縄７３の上方において略平行となるように伸縮連結腕部４５を摺動させ、再び操作ねじ２０を締め付けて水糸取付部１３を位置決め固定する。
【０１０１】
そして、適宜取り付けた水糸７５を基準とし、水糸７５から所定の深さで地面を掘削して図３および図７に示すように、根切り溝７７を形成し、この根切り溝７７の底部に図示しないコンクリート基礎を形成する。なお、水糸７５を張設する前に、地面に設けた白線に基づいて図示しないバックホウにてある程度の深さに地面を掘削する。この後、水糸７５を張設し、所定の深さとなるように深さを確認しつつ根切り溝７７を形成するなどしてもよい。
【０１０２】
（ブロック積み用アタッチメント）
次に、ブロック積み用アタッチメントの動作について説明する。なお、片腕水準形成装置に取り付ける構成について説明する。
【０１０３】
片腕水準形成装置３から伸縮連結腕部４５を取り外す。そして、片腕水準形成装置３の一側に、片腕水準形成装置３の杭部１５と同様にして伸縮連結杭部５７を略鉛直方向に沿って立設する。この後、片腕水準形成装置３の胴体部３１に設けた操作ねじ２０を緩め、胴体部３１が上下方向に移動可能にする。
【０１０４】
そして、移動可能になった片腕部４１の伸縮腕保持部４３にブロック積み用アタッチメント５のアタッチメント腕部５２を嵌挿するとともに、ブロック積み用アタッチメント５の伸縮支柱部５５の下端を伸縮連結杭部５７と嵌合させる。この後、伸縮支柱部５５の操作ねじ２０、片腕水準形成装置３の伸縮腕保持部４３の操作ねじ２０、および、片腕水準形成装置３の胴体部３１の操作ねじ２０をそれぞれ締め付け、位置決め固定する。
【０１０５】
さらに、伸縮連結支柱部５６を伸縮支柱部５５に嵌挿する。この後、トランシットなどを用いて伸縮支柱部５５に適宜印を設け、糸取付板３８が印の位置となるように移動し、伸縮支柱部５５の操作ねじ２０を適宜締め付け、所定の位置に位置決めし、ブロック積み用アタッチメント５を片腕水準形成装置３に組み付けて変則水準形成装置７を組立形成する。
【０１０６】
この後、糸取付板３８に水糸７５の一端を取り付け、水糸７５の他端側を対向する位置に組立形成した変則水準形成装置７のブロック積み用アタッチメント５の糸取付板３８に取り付ける。そして、この水糸７５を基準として、ブロック積みをする。
【０１０７】
（傾斜アタッチメント）
次に、傾斜アタッチメントの動作について説明する。なお、片腕水準形成装置に取り付ける構成について説明する。
【０１０８】
片腕水準形成装置３から伸縮連結腕部４５を取り外す。そして、片腕水準形成装置３の一側に、法面勾配に沿うようにして伸縮杭部６５を斜めに立設する。この後、片腕水準形成装置３の胴体部３１に設けた操作ねじ２０を緩め、胴体部３１が上下方向に移動可能にする。
【０１０９】
そして、移動可能になった片腕部４１の伸縮腕保持部４３に傾斜アタッチメント６の回動連結腕部６２を嵌挿するとともに、傾斜アタッチメント６の伸縮連結支柱部５６をあらかじめ嵌挿した伸縮支柱部５５の下端を伸縮杭部６５と嵌合させる。この際、回動連結腕部６２と伸縮支柱部５５との連結位置が法面の頂部の上方に位置するようにするとともに、伸縮支柱部５５が法面勾配と略平行となるようにする。この状態で、伸縮支柱部５５の操作ねじ２０、片腕水準形成装置３の伸縮腕保持部４３の操作ねじ２０、および、片腕水準形成装置３の胴体部３１の操作ねじ２０をそれぞれ締め付け、位置決め固定し、傾斜アタッチメント６を片腕水準形成装置３に組み付けて変則水準形成装置８を組立形成する。
【０１１０】
この後、回動連結腕部６２と伸縮支柱部５５との連結位置から法面の頂部までの高さ寸法を測定する。また、伸縮連結支柱部５６を糸取付板３８が連結位置から所定の距離となるように位置させて、対向して組立形成した変則水準形成装置８間で水糸７５を張設する。そして、水糸７５からあらかじめ測定しておいた高さ寸法分下方の位置が法面となるので、この位置に頂部が位置するように木杭などを打設する。このようにして、木杭などを適宜打設し、木杭の頂部が法面となるように整地することで、設定通りの勾配を有した法面を形成できる。
【０１１１】
〔水準形成システムの効果〕
上記一実施の形態によれば、次のような効果が得られる。
【０１１２】
（１）軸方向が略鉛直方向に沿って地面に立設した支柱部１１に、軸方向が略水平方向に沿う状態に、両腕水準形成装置２の場合には第１腕部３２ａおよび第２腕部３２ｂを、片腕水準形成装置３の場合には腕部４６を設け、水糸７５を略鉛直方向で異なる位置に取付可能な水糸取付部１３の糸取付板３８を第１腕部３２ａおよび第２腕部３２ｂ、あるいは腕部４６に設ける。このため、例えばコンクリート基礎を建造する際に、水糸７５を張設するために一対配設して各糸取付板３８の同一水平面となる位置で水糸７５を張設すればよく、従来の形成が煩雑な遣方のようにコンクリート基礎を形成する領域が囲まれることはなく、簡単な構造で容易に水平基準を形成でき、作業効率を向上できる。
【０１１３】
（２）軸方向が略鉛直方向に沿って地面に立設した支柱部１１に、軸方向が略水平方向に沿う状態で略鉛直方向に移動可能に第１腕部３２ａおよび第２腕部３２ｂを有した両腕部１２、あるいは腕部４６を有した片腕部４１を設け、これら第１腕部３２ａおよび第２腕部３２ｂ、あるいは腕部４６に水糸７５が取り付けられる糸取付板３８を設ける。このため、例えばコンクリート基礎を建造する際に、水糸７５を張設するために一対配設し、糸取付板３８が設けられる両腕部１２あるいは片腕部４１を糸取付板３８の位置で略同一水平面となる状態に適宜鉛直方向で移動させて水糸７５を張設すればよく、従来の形成が煩雑な遣方のようにコンクリート基礎を形成する領域が囲まれることはなく、簡単な構成で容易に水平基準を形成でき、作業効率を向上できる。
【０１１４】
（３）軸方向が略鉛直方向に沿って地面に立設した支柱部１１に、軸方向が略水平方向に沿う状態で第１腕部３２ａおよび第２腕部３２ｂ、あるいは腕部４６を設け、これら第１腕部３２ａおよび第２腕部３２ｂ、あるいは腕部４６に水糸７５が取り付けられる糸取付板３８を第１腕部３２ａおよび第２腕部３２ｂ、あるいは腕部４６の軸方向に沿って相対的に摺動可能に設ける。このため、例えばコンクリート基礎を建造する際に、水糸７５を張設するために一対配設し、第１腕部３２ａおよび第２腕部３２ｂ、あるいは腕部４６に対して適宜摺動して所定の位置に移動した糸取付板３８に水糸７５を張設することで、支柱部１１を立設する位置がずれていても水糸７５が所定の位置に張設されるので、従来の形成が煩雑な遣方のようにコンクリート基礎を形成する領域が囲まれることはなく、簡単な構成で容易に水糸７５による水平基準を形成でき、作業効率を向上できる。
【０１１５】
（４）支柱部１１に軸方向の一端が地面に埋設されて立設される杭部１５を設ける。このため、杭部１５を軸方向の一端が地面に埋設されて立設することにより支柱部１１が軸方向を略鉛直方向に沿って容易に立設され、構成が簡単で、製造性を向上できるとともに、設置および保管のスペースも縮小し、搬送や保守管理性も向上できる。
【０１１６】
（５）支柱部１１に設けた筋交い取付部１８に、筋交い部材２１の軸方向が支柱部１１の軸方向に対して交差するとともに互いの軸方向が交差する状態に取り付ける。このため、筋交い部材２１として例えば鉄筋棒などを用いることにより、簡単な構成で支柱部１１を軸方向が略鉛直方向に沿う状態に安定して立設できる。
【０１１７】
（６）支柱部１１を軸方向の長さ寸法が伸縮可能、すなわち例えば図４あるいは図８に示すように継部１６を適宜杭部１５に連結して支柱部１１としての長さ寸法を可変可能とする。このため、例えば傾斜する地面に設置する場合でも、支柱部１１を伸長すなわち継部１６を連結することにより、水平基準を形成可能に水糸７５を張設することが可能となって汎用性を向上できるとともに、支柱部１１を短縮すなわち継部１６を取り外すことにより、収納や搬送などが容易にできる。
【０１１８】
（７）両腕水準形成装置２として第１腕部３２ａおよび第２腕部３２ｂを軸方向が互いに略直交する状態に一対設ける。このため、例えば地縄７３の角部分において水糸７５を直交する状態で張設する場合でも、一台で２本の水糸７５を直交する状態に容易に張設でき、水平基準を容易に形成できる。
【０１１９】
（８）糸取付板３８に取り付けられる水糸７５の鉛直方向での移動を規制する位置決め手段としての取付孔３９を設ける。このため、取り付けた水糸７５の位置ずれを防止でき、また取付孔３９に水糸７５を結束することにより水糸７５の脱落も防止でき、安定して水糸７５を取り付けできる。
【０１２０】
（９）第１腕部３２ａおよび第２腕部３２ｂ、あるいは腕部４６の水平状態を検出する水準器を設ける。このため、第１腕部３２ａおよび第２腕部３２ｂ、あるいは腕部４６において軸方向に沿ったいずれの位置でも取り付ける水糸７５の水平位置が得られ、水糸７５の水平状態が得られる広範囲な取付位置を容易に得ることができ、水平基準を容易に形成できる。
【０１２１】
（１０）第２腕部３２ｂを腕保持部３３および連結腕部３５の連結により構成、すなわち長さ寸法を伸縮可能とする。このため、連結（伸長）することにより杭部１５からより離れた位置でも水糸７５を取り付けることができ、水糸７５の張設可能範囲が拡大し、水糸７５の張設作業が容易にできるとともに、連結腕部３５を腕保持部３３から取り外す（伸縮）ことにより、収納や搬送などが容易にできる。
【０１２２】
（１１）地縄７３の角部分、すなわちコンクリート基礎を形成するために地面に掘削される溝の角に対応する位置近傍に両腕水準形成装置２を配置する。このため、必要最小限の台数で水糸７５を張設して水平基準を形成することができる。
【０１２３】
（１２）少なくとも１対以上の両腕水準形成装置２および片腕水準形成装置３を組み合わせた水準形成システム１の各糸取付板３８に、トランシットを用いて同一水平面上に位置する印を設け、各糸取付板３８間に印の位置で水糸７５を張設し、この張設した水糸７５から所定の距離の位置にコンクリート基礎を形成する。このため、従来の遣方を形成する必要がなく容易に水平基準を形成でき、地面の掘削やコンクリート基礎の形成の際に遣方が邪魔となって作業性が低下することもなく、容易に効率よくコンクリート基礎を形成できる。
【０１２４】
（１３）片腕水準形成装置３の伸縮腕保持部４３に着脱可能にアタッチメント腕部５２を取り付けるとともに、このアタッチメント腕部５２に設けられ水糸７５が取り付けられる糸取付板３８を略鉛直方向に移動可能に設ける連結支柱部５１を軸方向が略鉛直方向に沿って地面に立設してブロック積み用アタッチメント５を取り付ける。このため、例えばコンクリート基礎を建造するために設置された片腕水準形成装置３に取り付けるのみで、ブロック積み用アタッチメント５を略鉛直状態にするための作業が不要で、かつ、筋交い部材２１を打設する作業をする必要がなく、容易に糸取付板３８が略鉛直方向に沿って移動可能な構成が得られ、コンクリート基礎の施工後にブロック積みなどの水平基準となる水糸７５を上下動させる構成が簡単な構成で容易に得られ、作業効率を向上できる。
【０１２５】
（１４）ブロック積み用アタッチメント５の伸縮連結支柱部５６に軸方向の一端側に糸取付板３８を設ける。このため、例えば伸縮連結杭部５７を連結する構成でも、糸取付板３８が下端側に位置するように伸縮連結支柱部５６を伸縮支柱部５５に嵌挿することにより、連結支柱部５１の下端部に糸取付板３８が位置する状態が得られる。また、糸取付板３８が上端側に位置するように伸縮連結支柱部５６を伸縮支柱部５５に嵌挿することにより、連結支柱部５１の上端部に糸取付板３８が位置する状態があられる。このため、必要最小限の操作ねじ２０でアタッチメント腕部５２が突設された構成でも糸取付板３８が下端側から上端側まで移動可能な構成が得られる。
