Description

【０００１】
【発明の属する技術分野】
この発明は、例えば公園や舗道、その他各所で、人為的に植栽される樹木を支持するための方法および構造の改良に関する。
【０００２】
【従来の技術】
従来、この種の発明として、予め地面に形成された植穴内に根鉢を収納し、その根鉢の上面を押え部材で固定するとともに、その押え部材と、地面に打ち込まれるアンカーとにワイヤーを連結し、そのワイヤーの緊縮力によって樹木を支持する構造が知られている。
しかし、この従来構成では、ワイヤーの上下方向の緊縮力によってのみ根鉢を支持固定するものであるため、地盤沈下等によりワイヤーが緩むおそれがあり、それによって根鉢に対する緊縮力が損なわれるという問題点があった。
そこで、本発明者は、特開２００１−５４３２７の稙栽樹木の支持構造に係る発明を提案し、本締め用締付部材と、仮締め用締付部材とを用いて、根鉢を強固に支持固定することができ、相応の成果を挙げている。
本発明者は、更に、鋭意研究の結果、支持杭にアンカーとなる根枷部材を取り付けて地中に埋設し、支持杭の引き抜き強度を高めて、根鉢が大きくても強固に支持することができるようにした植栽樹木の支持構造を開発し、本発明を完成するに至った。
【０００３】
【発明が解決しようとする課題】
この発明の課題は、支持杭に根枷取付具を設けてアンカーとなる木製の根枷部材を取り付けて地中に埋設し、締付部材によって根鉢を囲むように緊締された支持杭の引き抜き強度や根鉢の支持強度を高めることができるようにした植栽樹木の支持構造およびその方法を提供することにある。

【０００６】
【発明の実施の形態】
以下に、この発明の植栽樹木の支持構造およびその方法の好適実施例について図面を参照しながら説明する。
図１に示す第１実施例の植栽樹木の支持構造は、樹木Ｔの根鉢１を載置するために地面に形成された植え穴からなる凹部２と、上記凹部２内で根鉢１の周面に沿って、複数（図示例では４本）打ち込まれる丸太製の支持杭３と、各支持杭３に装着されて、前記凹部２内でアンカーとなる根枷部材４を横向きに取付ける根枷取付具５と、前記支持杭３で根枷取付具５より上方位置に設けられて、上記支持杭３相互を根鉢１に沿って締め付ける締付部材１０とからなっている。
【０００７】
ここで支持杭３は、先端を削った丸太が用いられるが、間伐採を使用するため廉価であって、白木で使用できて地上支柱で行われるクレオソート防腐処理をする必要がなく、土に還元される杉丸太を使用することが好ましい。
この支持杭３は、上記凹部２の中で、根鉢１の周面に沿って打ち込まれる。
打ち込みに際しては、締付後に支持杭３が垂直になるように多少斜めにして打ち込むことが好ましい。
【０００８】
この支持杭３には、中途位置に、予め、根枷取付具５を装着した構成であってもよいが、本実施例では、根枷取付具５は支持杭３と別体となっており、支持杭３が打ち込まれた後に、支持杭３に差し込まれて装着される。
【０００９】
即ち、本実施例で、根枷取付具５は鉄などの金属製で、支持杭３に差し込み可能な第１リング５ａと、該第１リング５ａに直交して固着されて根枷部材４を差し込み可能な第２リング５ｂとからなっている。　　　　　　　　　　　　　　従って、根枷部材４を支持杭３に装着するには、前記第１リング５ａを支持杭３に挿入し、凹部２の底まで差し込こむだけでよい。
【００１０】
次に、支持杭３には、前記根枷部材４の装着位置の上方に、ワイヤーロープ等を用いて支持杭３相互を緊締するための締付部材１０を、その上端が地上に突出しないような位置、図示例では凹部２の上端でほぼグランドラインと一致する位置に装着する。
締付部材１０は、適宜、公知構成のものを使用しうるが、本実施例の場合、一例として、第１締付具１１と、第２締付具１２とを用いている。
【００１１】
この第１締付具１１は、図４に示すように、リング１１ａの一方に、先端にワイヤーロープＷを結ぶためのボルト１１ｂを軸支したブラケット１１ｃを固着し、これと直交する位置に、アーム１１ｄを介して、ワイヤーロープＷを牽引して巻き取る逆転防止爪１１ｅ付きウインチ１１ｆを装着した構成からなっている。また、第２締付具１２は、定滑車となるシーブ１２ｂ付きリング１２ａからなっている。
【００１２】
そこで、図３に一例を示すように、１本の支持杭３に、前記第１締付具１１のリング１１ａを挿入して装着し、残りの支持杭３には、前記第２締付具１２のリング１２ａを挿入して装着する。
そして、第１締付具１１のボルト１１ｂに一端を結んだワイヤーロープＷを第２締付具１２のシーブ１２ｂに通して回し、他端を前記第１締付具１１のウインチ１１ｆで巻き取って、支持杭３相互を環状に巻かれたワイヤーロープＷの縮小方向に牽引して緊締する。
【００１３】
上記締付固定の後に、上記第１締付具１１や第２締付具１２のリング１１ａ、１２ａ上端に突出して地上に出る支持杭を切断する。
この支持杭３の切断片３’は、アンカーとなる根枷部材５として使用される。
即ち、この丸太からなる根枷部材５は、前記根枷取付具５の第２リング５ｂに差し込まれてアンカーとなる（図１（ｂ）参照）。
次いで、前記凹部２を埋め戻すことにより、根鉢１や根枷部材４、支持杭３が埋設され、支持杭３は、地下支柱として機能する。
【００１４】
上記実施例では、支持杭３の上部を切断して根枷部材４として利用したが、予め丸太などの木製の根枷部材４を別に用意しておいてもよい。
また、支持杭３は、上端まで地中に埋設される例を示したが、上部が地上に露出し、または突出するものであってもよい。
【００１５】
図２に示す第２実施例の植栽樹木Ｔの支持構造は、締付部材として、支持杭３の中途位置であって前記根枷取付具５より上方位置に取り付けられる本締め用締付部材１０Ａと、該本締め用締付部材１０Ａより上方位置に取り付けられる仮締め用締付部材１０Ｂとを上下二段に用いており、その他の構成は第１実施例と同様である。
【００１６】
ここで、本締め用締付部材１０Ａは、前記第１実施例の締付部材１０と同じく第１締付具１１と、第２締付具１２を用いた構成である。
仮締め用締付部材１０Ｂは、本締め用締付部材１０Ａと全く同様であってもよいが、本実施例では、前記第１締付具１１と、第２締付具１２のリング１１ａ、１２ａが、それぞれ支持杭３の上端に着脱可能に嵌着するキャップ形状からなっており、その他の構成は同様であるので、それらの説明を省略する。
【００１７】
上記構成からなっているので、締付部材の緊締時には、本締め用締付部材１０Ａと仮締め用締付部材１０Ｂとを用い、それぞれのワイヤロープＷを交互に締め付けて、支持杭３を根鉢２に沿って固定させる。
この実施例では、締付部材として、本締め用締付部材１０Ａと仮締め用締付部材１０Ｂとを用いるので、一層強固に全部の支持杭３を根鉢１に沿って締め付けることができる。
【００１８】
そして、この締付後に、本締め用締付部材１０Ａから上方に突出する支持杭３の上部を切断し、その切断片３’を根枷部材４として使用する。
上記切断片３’の切断時には、予め前記仮締め用締付部材１０Ｂの締付を解いて支持杭３から外しておいてもよいが、切断後に外してもよい。
【００１９】
そして、前述の通り、根枷部材４を根枷取付具５に差し込んで掛止め、あるいは固定してアンカーとなし、凹部２を埋め戻して、残存する支持杭３を、根鉢１や根枷部材４と共に埋設することにより地下支柱として機能させることができる。
支持杭３は、上端まで地中に埋設される例を示したが、この場合も、上部が地上に露出し、または突出するものであってもよい。
【００２０】
図５および図６に示す第３実施例の植栽樹木の支持構造は、締付部材（図示例では本締め用締付部材１０Ａ）の異なる実施例を示す。
その他の構成は、前記第２実施例と同様である。
この場合に、締付部材としてスライドリンク式の第３締付具１３と第４締付具１４とを用いている。
【００２１】
第３締付具１３と第４締付具１４とは、いずれも隣接する２つの支持杭３、３間に架け渡されて使用に供される。
即ち、第３締付具１３は、図８に示すように、左右に離間して、支持杭３に差し込まれる一対のリング１３ａと、この一対のリング１３ａに固着されたブラケット１３ｈを介してリング１３ａ間に架け渡された長さ調整可能なリンク１３ｉとを有している。
【００２２】
このリンク１３ｉは二重管構造によって、伸縮自在な構造となっており、内管に複数の長さ調整孔を穿設しておき、その選択された長さ調整孔の１つを、外管の基準孔と整合してボルト止めしてリンクを所望の長さに調整可能とする公知の長さ調整構造が用いられている。
【００２３】
また、一方のリング１３ａには、先端にワイヤーロープＷを結ぶためのボルト１３ｂを軸支したブラケット１３ｃを前記ブラケット１３ｈと直交する位置に固着している。また、他方のリング１３ａには、前記ブラケット１３ｈと直交する位置にアーム１３ｄを固着し、該アーム１３ｄに逆転防止爪１３ｅ付きウインチ１３ｆを枢着している。
【００２４】
次ぎに、第４締付具１４は、図９に示すように、支持杭３に差し込まれる一対のリング１４ａと、この一対のリング１４ａに固着されたブラケット１４ｈを介してリング１４ａ間に架け渡された長さ調整可能なリンク１４ｉとを有している点は第３締付具１３と同様である。
そして、一対のリング１４ａには、前記ブラケット１４ｈと直交する位置に、定滑車となるシーブ１４ｊを固着している。
【００２５】
第３実施例では、図６に示すように、４本打ち込まれた支持杭３の隣接する２つを１組として、一方の１組に、リンク１３ｉを長さ調節した第３締付具１３のリング１３ａを支持杭３に差し込んで装着し、他方の対向する１組に、第４締付具１４のリング１４ａを差し込んで装着する。
【００２６】
そして、第３締付具１３のブラケット１３ｃのボルト１３ｂに一端に結んだワイヤーロープＷを、第４締付具１４の両端のシーブ１４ｊ、１４ｊを通してから第３締付具１３のウインチ１３ｆに戻り、ウインチ１３ｆで結んで巻き取って支持杭３を緊締することができる。
【００２７】
この場合も、本締め用締付部材１０Ａと図示省略の仮締め用締付部材とで支持杭３を強固に締め付けて、本締め用締付部材１０Ａの各リングから上の部分を切断し、この切断片３’を根枷部材５として根枷取付具５に差し込み、前記凹部２を埋め戻して、前記実施例と同様にアンカーとして用いる。
【００２８】
次ぎに、図７および図１０に示す第４実施例の植栽樹木Ｔの支持構造は、８本の支持杭３を用いた場合の本締め用締付部材１０Ａの異なる実施例を示す。
その他の構成は、前記第２実施例と同様である。
この場合に、締付部材としてスライドリンク式の第５締付具１５を用いている。
【００２９】
第５締付具１５は、隣接する２つの支持杭間に架け渡されて使用に供されるもので、図１１に示すように、左右に離間して、支持杭３に差し込まれる一対のリング１５ａと、この一対のリング１５ａに固着されたブラケット１５ｈを介してリング１５ａ間に架け渡された長さ調整可能なリンク１５ｉとを有している。
このリンク１５ｉは前記第３締付具１３、第４締付具１４のリンク１３ｉ、１４ｉと同じ長さ調整構造を有している。
【００３０】
そして、一方のリング１５ａには、前記ブラケット１５ｈと直交する位置にアーム１５ｄを固着し、該アーム１５ｄに逆転防止爪１５ｅ付きウインチ１５ｆを枢着している。
また、他方のリング１５ａには、前記ブラケット１５ｈと直交する位置に、定滑車となるシーブ１５ｊを固着している。
【００３１】
そして第４実施例では、図１０に示すように、８本打ち込まれた支持杭３の隣接する２つを１組として、リンク１５ｉを長さ調節した４組の第５締付具１５がそのリング１５ａにそれぞれ支持杭３を差し込んで装着されている。
そして、それぞれの第５締付具１５のウインチ１５ｆは、他の第５締付具１５の対向するシーブ１５ｊとの間にワイヤーロープＷを掛け渡して締め付けている。
【００３２】
この第４実施例の植栽樹木Ｔの支持構造では、同一の第５締付具１５で連結されなかった隣接する支持杭３間の一対の根枷取付具５、５の第２リング５ｂ、５ｂを同軸線上に並べて、１本の長い根枷部材４を両者に差し込んで掛け渡している。
この場合、支持杭３は８本であるが、根枷部材４は４本でよい。
【００３３】
この根枷部材４は、支持杭３の上部を切断する場合は、支持杭３の切断する長さを前記実施例の場合よりも長く（隣接する支持杭３、３の間隔より長く）する必要があるが、少なくとも４本の支持杭３から上記根枷部材４を得ればよく、他の支持杭３からは、根枷部材４を得る必要はないので短くてもよい。
あるいは、支持杭３の切断片３’を根枷部材４として用いず、別に所定長さに切断した丸太を根枷部材４として予め準備するものでもよい。
【００３４】
次ぎに、図１２および図１３に示す第５実施例の植栽樹木Ｔの支持構造は、８本の支持杭３を用いた本締め用締付部材１０Ａの更に別の実施例を示す。
この場合に、締付部材として、第３実施例と同様に、図８の第３締付具１３と、図９の第４締付具１４とを組み合わせて用いている。
即ち、隣接する支持杭３、３間に第３締付具１３と第４締付具１４とを、相互に対向するように各２組づつ使用する。
【００３５】
従って、前記第３実施例における締付部材を、クロス状に組み合わせた用いた態様となる。
また、各根枷取付具５には、それぞれ支持杭３の切断片３’からなる根枷部材５が差し込まれる。
なお、図示例では、根枷取付具５の取付位置の他の一例として、交互にやや高低差をつけているが、全てを同一高さ位置としてもよい。
このように根枷取付具５の取付位置は、一律でなく適宜に変更してもよい。
その他の構成は前記実施例と同様であるので、その説明を省略する。
【００３６】
次ぎに、図１４および図１５に示す第６実施例の植栽樹木Ｔの支持構造は、１２本の支持杭３を用いた本締め用締付部材１０Ａの別の実施例を示す。
この場合に、上記締付部材１０Ａには、図８の第３締付具１３のみを用いている。
即ち、隣接する支持杭３、３間に第３締付具１３を６組用いており、対向する第３締付具１３間においては、ボルト１３ｂを軸支したブラケット１３ｃと、
逆転防止爪１３ｅ付きウインチ１３ｆとが対峙するように配置される。
【００３７】
そして、ワイヤーロープＷの一端を前記ボルト１３ｂに結び、他端をウインチ１３ｆで巻き取り締め付けている。
また、第４実施例と同様に、同一の第３締付具１３で連結されなかった隣接する支持杭３間の一対の根枷取付具５、５の第２リング５ｂ、５ｂを同軸線上に並べて、１本の長い根枷部材４を両者に差し込んで掛け渡している。
この場合、支持杭３は１２本であるが、根枷部材４は６本でよい。
その他の構成は前記実施例と同様であるので説明を省略する。
【００３８】
なお、第３実施例から第６実施例の植栽樹木の支持構造は、全て仮締め用締付部材と本締め用締付部材を用いた場合について説明したが、仮締め用締付部材を用いずに、締付部材のみを用いた場合も同様であるので、その説明を省略する。
【００３９】
上記実施例では、第１から第５締付具を例示したが、締付具の構成はこれらに限らず、ワイヤーロープなどの線条材を牽引して支持杭を締め付ける公知構成を用いることができる。
また、前記実施例では、根枷取付具や締付具は、支持杭を打ち込んだ後に取り付けるようになっているが、この発明では、根枷取付具およびまたは締付具は予め支持杭に取り付けられているものでもよい。
【００４０】
更に、締付部材は、本締め用と仮締め用と用いる場合に、両者に用いる締付具は、同一のものであっても、異なるものであってもよい。
また、仮締め専用に、キャップ式などの支持杭から取り外しやすい構造の締付具を用いてもよい。
また、根鉢に沿って打ち込む支持杭の数は、実施例に限定されるものではなく、根鉢の大きさや支持強度に応じて適宜変更することができ、締付部材によるワイヤーロープの締付方法も支持杭の数や配置に応じて適宜に変更することができる。
【００４１】
また仮締め用締付部材や本締め用締付部材は、支持杭に固定されるものでも、あるいは作業者の手で持って締め付けるまで一時的に掛止められるものでもよい。
例えば、ワイヤーロープだけで支持杭を根鉢に沿って緊締するだけの構造であってもよい。
同様に根枷取付具は、根枷を横向きにした状態で支持杭に連結するものであればよく、実施例の構造に限定されない。
その他、要するにこの発明の要旨を変更しない範囲で種々設計変更しうること勿論である。
【００４２】
【発明の効果】
この発明の植栽樹木の支持構造では、支持杭に根枷取付具を設けてアンカーとなる木製の根枷部材を取り付けて地中に埋設するので、締付部材によって根鉢を囲むように緊締された支持杭は、引き抜き強度や根鉢の支持強度を高めることができるので、根鉢の大小にかかわらず支持することができる。
また、支持杭やアンカーとなる根枷部材は木製であるので、根鉢が根付いた後には地中で土に還元されるので、環境を損なうおそれがない。
更に、支持杭の上部を切断して根枷部材として用いる場合は、予め根枷部材を用意する必要がなく、無駄がない。
そして、支持杭を地中に埋設すれば、簡単な構造で強固な地下支柱を廉価で実現することができ、極めて有益である。

Also, the number of support piles driven along the root mortar is not limited to the embodiment, and can be appropriately changed according to the size and the support strength of the root mortar. The method can be appropriately changed according to the number and arrangement of the support piles.
[0041]
Further, the temporary tightening member and the final tightening member may be fixed to the support pile, or may be temporarily stopped by the operator's hand until they are tightened.
For example, a structure in which the support pile is simply tightened along the root pot with only a wire rope may be used.
Similarly, the shackle attachment is not limited to the structure of the embodiment as long as the shackle is connected to the support pile with the shackle turned sideways.
In other words, it goes without saying that various design changes can be made without departing from the scope of the present invention.
[0042]
【The invention's effect】
In the support structure of the planted tree according to the present invention, the anchoring fixture is provided on the supporting pile, and the wooden anchoring member serving as the anchor is mounted and buried in the ground, so that the fastening member surrounds the root mortar. The support pile thus set can increase the pull-out strength and the support strength of the root mortar, so that it can be supported regardless of the size of the root mortar.
In addition, since the shackle members serving as support piles and anchors are made of wood, they are returned to the soil in the ground after the root mortar is rooted, so there is no risk of damaging the environment.
Furthermore, when the upper part of the support pile is cut and used as a shackle member, there is no need to prepare a shackle member in advance, and there is no waste.
If the support pile is buried in the ground, a strong underground column with a simple structure can be realized at low cost, which is extremely useful.
