Description

本発明は、樹木の支持施工方法と、そのような樹木の支持施工方法に用いる根鉢用固定用具に関する。   TECHNICAL FIELD The present invention relates to a tree support construction method and a root pot fixing tool used for such a tree support construction method.

従来、この種の樹木を支持施工する技術として、たとえば特許文献１乃至３のような特許出願がなされている。特許文献１に係る発明においては、複数の固定板（根鉢用接触体）が根鉢の周面に接触され、それぞれの根鉢用接触体にワイヤ（支持ベルト）が取り付けられて樹木幹部の周囲に配置される一方、根鉢用接触体に杭が連結され、その杭が根鉢の周辺土壌に打設されることにより、根鉢用接触体で根鉢の周面が押さえ付けられ、その根鉢用接触体、ワイヤ、杭によって樹木が支持施工されることとなる。   Conventionally, patent applications such as Patent Documents 1 to 3 have been filed as techniques for supporting and constructing this type of tree. In the invention according to Patent Document 1, a plurality of fixing plates (root pot contact bodies) are brought into contact with the peripheral surface of the root pot, and a wire (support belt) is attached to each root pot contact body to While being placed around, the pile is connected to the root pot contact body, and by placing the pile on the surrounding soil of the root pot, the peripheral surface of the root pot is pressed down by the root pot contact body, The tree is supported and constructed by the root pot contact body, the wire, and the pile.

また特許文献２に係る発明は、上記特許文献１の周辺土壌に打設される杭に代えて植栽ベース（根鉢用載置体）が用いられ、その植栽ベース上に根鉢が載置され、根鉢に接触される押圧板（根鉢用接触体）と植栽ベースとに連結部材が連結されるとともに、押圧板に連結具を介して樹木幹部の周囲に配置される結合ロープ（支持ベルト）が連結され、押圧板、結合ロープ、植栽ベースによって樹木が支持施工されることとなる。   Moreover, the invention which concerns on patent document 2 is replaced with the pile cast | placed in the surrounding soil of the said patent document 1, and a planting base (mounting body for root pots) is used, and a root pot is mounted on the planting base. The connecting rope is placed around the trunk of the tree via a connector while the connecting member is connected to the pressing plate (root pot contact body) placed in contact with the root pot and the planting base. (Support belt) is connected, and trees are supported by the pressing plate, the connecting rope, and the planting base.

上記特許文献１に係る発明及び特許文献２に係る発明は、根鉢用接触体が根鉢の側面と上面の境界部分である肩部に接触されるが、根鉢用接触体が根鉢の側面に接触される特許文献３のような出願もなされている。この特許文献３に係る発明では、根鉢用接触体とともに根鉢用載置体や支持ベルトが用いられる点で、上記特許文献１に係る発明及び特許文献２に係る発明と共通する。   In the invention according to Patent Document 1 and the invention according to Patent Document 2, the root pot contact body is brought into contact with the shoulder that is the boundary between the side surface and the upper surface of the root pot. An application such as Patent Document 3 in contact with the side surface has also been made. The invention according to Patent Document 3 is common to the invention according to Patent Document 1 and the invention according to Patent Document 2 in that a root pot mounting body and a support belt are used together with the root pot contact body.

上記特許文献１乃至３に係る発明では、いずれも支持ベルトの締め付け力、該支持ベルトの締め付けに伴う根鉢用接触体の根鉢に対する押圧力等によって根鉢が固定されて樹木が支持施工されることとなるが、根鉢用接触体は、根鉢に単に当たっているだけであるので、たとえば根鉢を載置している地盤が沈下する場合、或いは風等によって樹木に傾倒力が作用するような場合に、当該根鉢に当たっていた位置から根鉢用接触体が位置ずれするおそれがある。そして、根鉢用接触体が位置ずれすると、支持ベルトが緩むことにもなるので、根鉢に対する根鉢用接触体の押圧力が低下することとなっていた。本来、支持ベルトは上記地盤沈下等が生じるだけでも緩むことになるが、特に、根鉢用接触体が位置ずれすることで、支持ベルトの緩みも一層顕著となるので、その分、根鉢に対する根鉢用接触体の押圧力の低下が著しいものとなっていた。このため根鉢８が確実に固定されず、結果として図４９の２点鎖線に示すように根鉢８が鉛直方向に対して傾くおそれがあるという問題が生じることとなった。   In the inventions according to Patent Documents 1 to 3, the root pots are fixed by the tightening force of the support belt, the pressing force against the root pots of the contact member for root pots accompanying the tightening of the support belt, and the tree is supported and constructed. However, since the contact body for the root pot simply hits the root pot, for example, when the ground on which the root pot is placed sinks, or a tilting force acts on the tree due to wind or the like. In such a case, there is a possibility that the root pot contact body may be displaced from the position where it hits the root pot. When the root pot contact body is displaced, the support belt is also loosened, so that the pressing force of the root pot contact body against the root pot is reduced. Originally, the support belt is loosened only by the above ground subsidence, etc., but in particular, since the root contactor is displaced, the loosening of the support belt becomes more prominent. The pressing force of the root pot contact body was greatly reduced. For this reason, the root pot 8 is not securely fixed, resulting in a problem that the root pot 8 may be inclined with respect to the vertical direction as indicated by a two-dot chain line in FIG.

本発明は、上記のような問題点に鑑みてなされたもので、上記従来の技術に比べて、根鉢をより確実に固定することができ、地盤沈下が生じた場合や樹木に傾倒力が作用する場合における、鉛直方向に対する根鉢の傾きをより好適に防止することができる樹木の支持施工方法と、その支持施工方法に用いる根鉢用固定用具を提供することを課題とするものである。   The present invention has been made in view of the above-described problems, and can fix the root pot more reliably as compared with the conventional technique described above, and when the ground subsidence occurs or the tree has a tilting force. It is an object of the present invention to provide a tree support construction method that can more suitably prevent the inclination of the root pot with respect to the vertical direction when acting, and a root pot fixing tool used in the support construction method. .

本発明は、このような課題を解決するために、樹木の根鉢に根鉢用接触体を接触させ、該根鉢用接触体で根鉢を押圧して該根鉢を固定することにより樹木を支持施工する樹木の支持施工方法において、前記根鉢に根鉢用接触体を接触させた状態で該根鉢用接触体を外側から保持するための根鉢用接触体固定部材を前記根鉢に食い込ませ、該根鉢用接触体固定部材で前記根鉢用接触体を根鉢に固定することを特徴とする樹木の支持施工方法を提供するものである。   In order to solve such a problem, the present invention makes a tree root by contacting the root pot with a root pot of a tree and pressing the root pot with the root pot contact body to fix the root pot. In the support construction method of a tree to be supported, a root pot contact body fixing member for holding the root pot contact body from the outside in a state where the root pot contact body is in contact with the root pot. It is intended to provide a method for supporting and supporting a tree, wherein the root pot contact body is fixed to the root pot by the root pot contact body fixing member.

また本発明は、樹木の根鉢を固定して該樹木を支持するために用いられ、前記根鉢に接触して該根鉢を押圧する根鉢用接触体が具備された根鉢用固定用具であって、前記根鉢に前記根鉢用接触体を接触させた状態で根鉢に食い込ませて前記根鉢用接触体を外側から保持するとともに前記根鉢用接触体を根鉢に固定する根鉢用接触体固定部材がさらに具備されていることを特徴とする根鉢用固定用具を提供するものである。   The present invention also relates to a root pot fixing tool used for fixing a root pot of a tree and supporting the tree, and comprising a contact member for a root pot that contacts the root pot and presses the root pot. The root pot is bitten into the root pot while the root pot contact body is in contact with the root pot to hold the root pot contact body from the outside and the root pot contact body is fixed to the root pot. The present invention provides a root pot fixing tool, further comprising a pot contact body fixing member.

本発明においては、上記のように、根鉢用接触体を根鉢に接触させた状態で、該根鉢用接触体を外側から保持して根鉢に固定するための根鉢用接触体固定部材を根鉢に食い込ませるので、地盤沈下が生じた場合や樹木に傾倒力が作用する場合においても、根鉢に接触した位置から根鉢用接触体が位置ずれするのが極力防止されることとなり、その結果、根鉢に対する根鉢用接触体の押圧力の低下が極力防止されることとなる。また根鉢用接触体固定部材が根鉢に食い込むことによる食い込み力も根鉢に対して作用するので、そのような根鉢用接触体固定部材の根鉢に対する食い込み力と、該根鉢用接触体固定部材によって外側から保持、固定されて根鉢に対する位置ずれが極力防止される根鉢用接触体の押圧力との双方が根鉢に対して作用することで、上記従来の樹木の支持施工技術に比べて、根鉢をより確実に固定することができ、地盤沈下が生じた場合や樹木に傾倒力が作用する場合における、鉛直方向に対する根鉢の傾きをより確実に防止することが可能となる。   In the present invention, as described above, the root pot contact body fixing for holding the root pot contact body from the outside and fixing it to the root pot in a state where the root pot contact body is in contact with the root pot. Since the member is bitten into the root pot, even when ground subsidence occurs or when tilting force acts on the tree, the root pot contactor is prevented from being displaced from the position in contact with the root pot as much as possible. As a result, a decrease in the pressing force of the root pot contact body against the root pot is prevented as much as possible. Further, since the biting force due to the root pot contact body fixing member biting into the root pot also acts on the root pot, the biting force of the root pot contact body fixing member with respect to the root pot, and the root pot contact body The above conventional tree support construction technology because both the pressing force of the root pot contactor that is held and fixed from the outside by the fixing member and prevented from being displaced relative to the root pot as much as possible acts on the root pot. Compared to the above, the root pot can be fixed more reliably, and it is possible to more reliably prevent the inclination of the root pot relative to the vertical direction when land subsidence occurs or when tilting force acts on the tree. Become.

また本発明においては、根鉢用接触体が複数具備され、一つの根鉢用接触体と他の根鉢用接触体との間に掛け回される支持ベルトがさらに具備されていてもよい。このような支持ベルトが具備される場合には、根鉢の周囲に複数の根鉢用接触体が配置され、一つの根鉢用接触体と他の根鉢用接触体との間に支持ベルトが掛け回され、該支持ベルトを締め付けることによって前記根鉢用接触体が根鉢に押し付けされ、前記支持ベルトによって根鉢に押し付けられた状態の根鉢用接触体が、前記根鉢用接触体固定部材で根鉢に固定されることとなる。   In the present invention, a plurality of contact members for root pots may be provided, and a support belt that is wound around between one contact member for root pots and another contact member for root pots may be further provided. When such a support belt is provided, a plurality of root pot contact bodies are arranged around the root pot, and the support belt is provided between one root pot contact body and another root pot contact body. The root pot contact body is pressed against the root pot by tightening the support belt, and the root pot contact body pressed against the root pot by the support belt is the root pot contact body. It will be fixed to the root pot with the fixing member.

このような支持ベルトが根鉢用接触体に掛け回され、支持ベルトが締め付けられることで該支持ベルトに緊締力が生じると、根鉢に対して根鉢用接触体の押圧力が作用することとなる。そして、上記のように支持ベルトを締め付けることによって前記根鉢用接触体で根鉢を押圧した状態で、根鉢用接触体固定部材が根鉢用接触体を外側から保持しつつ根鉢に食い込むことで、根鉢に対する根鉢用接触体の位置ずれがより確実に防止されることとなる。   When such a support belt is wound around the root pot contact body and the support belt is tightened to generate a tightening force on the support belt, the pressing force of the root pot contact body acts on the root pot. It becomes. Then, the root pot contact body fixing member bites into the root pot while holding the root pot contact body from the outside in a state where the root pot is pressed by the root pot contact body by tightening the support belt as described above. Thereby, the position shift of the contact member for the root pot with respect to the root pot will be more reliably prevented.

このように、支持ベルトの締め付けによって根鉢用接触体が固定されて根鉢用接触体の位置ずれがより確実に防止される状態で、該根鉢用接触体の外側から該根鉢用接触体を保持しつつ根鉢用接触体固定部材を根鉢に食い込ませることで、根鉢に対する根鉢用接触体の押圧力の低下をより好適に防止できることとなり、根鉢を固定する効果がより向上することとなる。   In this manner, the root pot contact body is fixed from the outside of the root pot contact body in a state where the root pot contact body is fixed by tightening the support belt and the positional displacement of the root pot contact body is more reliably prevented. By causing the root pot contact body fixing member to bite into the root pot while holding the body, it is possible to more suitably prevent a decrease in the pressing force of the root pot contact body against the root pot, and the effect of fixing the root pot is more Will be improved.

さらに本発明においては、根鉢を載置するための根鉢用載置体がさらに具備されていてもよい。このような根鉢用載置体に根鉢が載置される場合には、連結用部材が根鉢用接触体と根鉢用載置体とに連結されることが望ましい。このような連結用部材が根鉢用接触体と根鉢用載置体とに連結されることによって、根鉢用接触体が根鉢に対して位置ずれするのが好適に防止されることとなる。また、この場合において、上記支持ベルトが樹木の幹部の周囲に配置されて根鉢用接触体に掛け回される場合には、根鉢用接触体の上側は支持ベルトの緊締力によって固定され、根鉢用接触体の下側は根鉢用載置体に連結された連結用部材によって固定され、根鉢用接触体の上下で支持ベルトと連結用部材によって根鉢が固定されることになるので、根鉢用接触体の位置ずれがより確実に防止されることになり、根鉢に対する根鉢用接触体の押圧力の低下をより好適に防止できることとなる。   Furthermore, in this invention, the mounting body for root pots for mounting a root pot may further be comprised. When a root pot is placed on such a root pot mounting body, it is desirable that the connecting member be connected to the root pot contact body and the root pot mounting body. By connecting such a connecting member to the root pot contact body and the root pot mounting body, the root pot contact body is preferably prevented from being displaced with respect to the root pot. Become. In this case, when the support belt is arranged around the trunk of the tree and is hung around the root pot contact body, the upper side of the root pot contact body is fixed by the tightening force of the support belt, The lower side of the root pot contact body is fixed by a connecting member connected to the root pot mounting body, and the root pot is fixed by the support belt and the connecting member above and below the root pot contact body. Therefore, the positional displacement of the root pot contact body can be prevented more reliably, and a decrease in the pressing force of the root pot contact body relative to the root pot can be more suitably prevented.

本発明によって、根鉢をより確実に固定することができ、地盤沈下が生じた場合や樹木に傾倒力が作用する場合における、鉛直方向に対する根鉢の傾きをより好適に防止することができる樹木の支持施工方法と、その支持施工方法に用いる根鉢用固定用具を提供することが可能となる。   According to the present invention, the root pot can be more reliably fixed, and the tree that can more suitably prevent the inclination of the root pot with respect to the vertical direction when ground subsidence occurs or when a tilting force acts on the tree. It is possible to provide a support construction method and a root pot fixing tool used in the support construction method.

接触体中央片２には複数（図１の例では６個）の四角形の孔が穿設されており、それらの孔のうち、５個の孔４ｂ、…は同じ大きさに形成され、最上部の孔４ａは、他の孔４ｂよりも大きく形成されている。この最上部の孔４ａの略中央の位置には、後述する支持ベルトを掛止するための棒状の掛止体５が設けられている。この掛止体５は、図２に示すように前記接触体中央片２を構成する鋼材の一部を湾曲させて形成された湾曲部６内に挿入されることによって設けられている。   A plurality of (six in the example of FIG. 1) quadrangular holes are formed in the contact body central piece 2, and among these holes, the five holes 4b,... The upper hole 4a is formed larger than the other holes 4b. A rod-like hook body 5 for hooking a support belt, which will be described later, is provided at a substantially central position of the uppermost hole 4a. As shown in FIG. 2, the retaining body 5 is provided by being inserted into a curved portion 6 formed by curving a part of the steel material constituting the contact body central piece 2.

また、該掛止体５より上側の最上部の孔４ａの背面側に、前記接触体頭部片３の頭部片上部３ａが位置するように、接触体頭部片３が接触体中央片２の上部２ａの背面側に固着されている。そして、掛止体５より上側の接触体中央片２及び接触体頭部片３が、掛止体５より下側の接触体中央片２及び接触体頭部片３に対してわずかに折り曲げて形成されている。さらに、接触体頭部片３の頭部片上部３ａの略中央には、後述するボルト挿入用の孔７が穿設されている。   Further, the contact body head piece 3 is placed on the contact body center piece so that the head piece upper part 3a of the contact body head piece 3 is positioned on the back side of the uppermost hole 4a above the hooking body 5. 2 is fixed to the back side of the upper portion 2a. Then, the contact body center piece 2 and the contact body head piece 3 above the latch body 5 are slightly bent with respect to the contact body center piece 2 and the contact body head piece 3 below the latch body 5. Is formed. Furthermore, a bolt insertion hole 7 to be described later is formed in the approximate center of the head piece upper portion 3 a of the contact body head piece 3.

上記のように構成された根鉢用接触体１において、掛止体５より下側の接触体中央片２及び接触体頭部片３は真っすぐに形成されているので、鉛直方向に配置して根鉢の側面に接触されるが、掛止体５より上側の接触体中央片２及び接触体頭部片３は、掛止体５より下側の部分に対してわずかに折り曲げて形成されているので、根鉢の肩部に接触されうる。   In the root pot contact body 1 configured as described above, the contact body center piece 2 and the contact body head piece 3 below the hook body 5 are formed straight, so that they are arranged in the vertical direction. The contact body central piece 2 and the contact body head piece 3 above the hook body 5 are slightly bent with respect to the lower part of the hook body 5. Therefore, it can contact the shoulder of the root pot.

上記図１及び図２に示す根鉢用接触体１は、主として根鉢の側面に接触するものの、根鉢の肩部にも接触しうるが、この図１及び図２の形態の根鉢用接触体１に限らず、根鉢の側面のみに接触するような根鉢用接触体１を用いることもできる。   The root pot contact body 1 shown in FIG. 1 and FIG. 2 mainly contacts the side surface of the root pot, but can also contact the shoulder of the root pot, but for the root pot in the form of FIG. 1 and FIG. Not only the contact body 1, but the root pot contact body 1 that contacts only the side surface of the root pot can also be used.

また根鉢の肩部に接触するようなものとして、たとえば図３に示すような、一般に肩パットと称される根鉢用接触体１を用いることも可能である。この根鉢用接触体１は、複数の孔４を有して略ハシゴ形状に形成されており、図４に示すよう折り曲げられつつ根鉢８の肩部８ｂに接触されて使用されるものである。   Moreover, as a thing which contacts the shoulder part of a root pot, it is also possible to use the contact body 1 for root pots generally called a shoulder pad as shown, for example in FIG. The root pot contact body 1 has a plurality of holes 4 and is formed in a substantially ladder shape, and is used while being bent as shown in FIG. 4 while being in contact with the shoulder portion 8b of the root pot 8. is there.

根鉢用接触体は、後述する根鉢用接触体固定部材によって外側から好適に保持されるためには、上記図１乃至図４に示すように、複数の孔を有する略ハシゴ形状に形成されたような形状のものが望ましい。ただし、根鉢用接触体の形状はこれに限定されるものではなく、孔のない板状に形成されたようなものであってもよい。要は、後述する根鉢用接触体固定部材によって外側から保持されうるようなものであれば、その形状は問うのではなく、種々の形状の根鉢用接触体を使用することができる。   The root pot contact body is formed in a substantially ladder shape having a plurality of holes as shown in FIGS. 1 to 4 in order to be suitably held from the outside by a root pot contact body fixing member described later. Such a shape is desirable. However, the shape of the root pot contact body is not limited to this, and it may be formed in a plate shape without holes. In short, as long as it can be held from the outside by a root pot contact body fixing member described later, the shape of the root pot contact body is not questioned, and various shapes of root pot contact bodies can be used.

根鉢の外周面に配置される根鉢用接触体の数は、たとえば４個配置され、或いは３個配置される等、根鉢の大きさに応じて変更可能である。根鉢用接触体の数は１個であってもよいが、後述する支持ベルトを掛け回して支持ベルトを締め付けることによって根鉢用接触体に根鉢に対する押圧力を生じさせるためには、複数の根鉢用接触体が用いられるのが望ましい。また、根鉢用接触体としては、たとえば金属製のものが用いられるが、その材質も限定されるものではない。   The number of root pot contacts arranged on the outer peripheral surface of the root pot can be changed according to the size of the root pot, for example, four or three. The number of root pot contact bodies may be one, but in order to generate a pressing force against the root pots in the root pot contact bodies by tightening the support belt by winding the support belt described later, It is desirable to use a root contactor. Further, as the root pot contact body, for example, a metal one is used, but the material is not limited.

根鉢用接触体固定部材は、要は、根鉢用接触体の外側から保持しつつ根鉢に打ち込むことによって根鉢を固定するようなものであればよく、その形状は問わない。たとえば、図５及び図６に示すように、正面略長方形状、側面略コ字状に形成された根鉢用接触体固定部材９を用いることができる。この根鉢用接触体固定部材９の略中央には、ボルトを挿入させるための孔１０が穿設されている。   The root pot contact body fixing member may be anything as long as it fixes the root pot by driving into the root pot while holding it from the outside of the root pot contact body, and the shape is not limited. For example, as shown in FIGS. 5 and 6, a root pot contact body fixing member 9 formed in a substantially rectangular front shape and a substantially U-shaped side surface can be used. A hole 10 for inserting a bolt is formed in the approximate center of the root pot contact body fixing member 9.

この図５及び図６に示す根鉢用接触体固定部材９の使用例について、上記図１及び図２に示す根鉢用接触体１に適用する場合について説明すると、図７及び８に示すように、根鉢用接触体固定部材９で根鉢用接触体１を保持させつつ、根鉢用接触体固定部材９を根鉢８の側面８ａに打ち込む。より具体的には、根鉢用接触体固定部材９の中央片９ａが、根鉢用接触体１の接触体頭部片３の頭部片下部３ｃの正面に接触し、根鉢用接触体固定部材９の両側片９ｂ、９ｂが前記接触体頭部片３の頭部片下部３ｃの両側に跨るように、根鉢用接触体固定部材９が根鉢８の側面８ａに打ち込まれることとなる。このように根鉢用接触体固定部材９が根鉢８の側面８ａに打ち込まれることで、根鉢用接触体固定部材９が根鉢８の側面８ａに食い込むこととなる。   The usage example of the root pot contact body fixing member 9 shown in FIG. 5 and FIG. 6 will be described with reference to the case where it is applied to the root pot contact body 1 shown in FIG. 1 and FIG. The root pot contact body fixing member 9 is driven into the side surface 8 a of the root pot 8 while holding the root pot contact body 1 with the root pot contact body fixing member 9. More specifically, the central piece 9a of the root pot contact body fixing member 9 contacts the front of the head piece lower part 3c of the contact body head piece 3 of the root pot contact body 1, and the root pot contact body. The root pot contact body fixing member 9 is driven into the side surface 8a of the root pot 8 so that both side pieces 9b, 9b of the fixing member 9 straddle both sides of the head piece lower portion 3c of the contact body head piece 3; Become. In this way, the root pot contact body fixing member 9 is driven into the side surface 8 a of the root pot 8, so that the root pot contact body fixing member 9 bites into the side surface 8 a of the root pot 8.

さらに、ボルト１１が根鉢用接触体固定部材９の孔１０に挿入されることによって、根鉢用接触体固定部材９と根鉢用接触体１との相互間が固定されることとなる。この場合には、接触体頭部片３の頭部片下部３ｃにも、予め孔が穿設されている必要がある。このような頭部片下部３ｃの孔は、たとえば施工現場でドリル等によって穿設されうる。   Further, the bolt 11 is inserted into the hole 10 of the root pot contact body fixing member 9 so that the root pot contact body fixing member 9 and the root pot contact body 1 are fixed to each other. In this case, a hole needs to be drilled in advance in the head piece lower portion 3c of the contact body head piece 3 as well. Such a hole in the lower part 3c of the head piece can be drilled by a drill or the like at a construction site, for example.

また、上記図５及び図６の根鉢用接触体固定部材９と同様に、正面略長方形状、側面略コ字状に形成されているが、図９に示すように、略コ字状に形成された両側片９ｂ、９ｂの先端部９ｃ、９ｃが略楔形に形成されたような根鉢用接触体固定部材９を用いることもできる。より詳細には、図９の実施形態では、根鉢用接触体固定部材９の両側の先端部９ｃが側面略三角形状に形成され、最先端部９ｄより手前側の頂角の部分９ｅは、根鉢用接触体固定部材９の側片９ｂの外面より外側に突出して形成されており、その頂角の部分９ｅから最先端部９ｄに向かって内向きのテーパ状となるように先端部９ｃが形成されている。   Further, like the root pot contact body fixing member 9 shown in FIGS. 5 and 6, the front surface is formed in a substantially rectangular shape and the side surface is formed in a substantially U shape. However, as shown in FIG. It is also possible to use a root pot contact body fixing member 9 in which the tip portions 9c, 9c of the formed side pieces 9b, 9b are formed in a substantially wedge shape. More specifically, in the embodiment of FIG. 9, the tip portions 9c on both sides of the root pot contact body fixing member 9 are formed in a substantially triangular shape on the side, and the apex portion 9e on the front side of the most distal portion 9d is The tip 9c is formed so as to protrude outward from the outer surface of the side piece 9b of the root pot contact body fixing member 9, and has an inward taper shape from the apex portion 9e toward the most distal portion 9d. Is formed.

この図９の実施形態では、根鉢用接触体固定部材９の両側片９ｂ、９ｂの先端部９ｃ、９ｃが略楔形に形成されているので、根鉢用接触体固定部材９を根鉢の側面に容易に打ち込むことができる。また側面略三角形状に形成された根鉢用接触体固定部材９の最先端部９ｄより手前側の頂角の部分９ｅは、側片９ｂの外面より外側に突出して形成されているので、根鉢用接触体固定部材９が一旦根鉢８の側面８ａに打ち込まれた後は、前記側片９ｂの外面より外側に突出した頂角の部分９ｅが抵抗力として作用して根鉢用接触体固定部材９が根鉢８の側面８ａから不用意に抜け出るのが好適に防止される。   In the embodiment of FIG. 9, since the tip portions 9c, 9c of both side pieces 9b, 9b of the root pot contact body fixing member 9 are formed in a substantially wedge shape, the root pot contact body fixing member 9 is Can be easily driven into the side. Further, the apex angle portion 9e on the nearer side than the most distal end portion 9d of the root pot contact body fixing member 9 formed in a substantially triangular shape on the side surface is formed so as to protrude outward from the outer surface of the side piece 9b. After the pot contact member fixing member 9 is once driven into the side surface 8a of the root pot 8, the apex angle portion 9e protruding outward from the outer surface of the side piece 9b acts as a resistance force so that the contact member for the root pot The fixing member 9 is preferably prevented from inadvertently coming out of the side surface 8a of the root pot 8.

また、根鉢用接触体固定部材９として、図１０に示すように、根鉢用接触体固定部材９の側片９ｂの先端部９ｃが、３つの三角形が長さ方向に連続するような釘状に形成されたものを用いることもできる。この図１０の実施形態では、それぞれ３つの三角形の両側の頂角の部分９ｅが、根鉢用接触体固定部材９の側片９ｂの外面より外側に突出して形成されており、その頂角の部分９ｅから先端側に向かって内向きのテーパ状となるように形成されている。そして、先端部９ｃは尖った略楔形に形成されている。   Further, as shown in FIG. 10, the tip 9 c of the side piece 9 b of the root pot contact body fixing member 9 is a nail whose three triangles are continuous in the length direction as the root pot contact body fixing member 9. What was formed in the shape can also be used. In the embodiment of FIG. 10, the apex angle portions 9e on both sides of each of the three triangles are formed to protrude outward from the outer surface of the side piece 9b of the root pot contact body fixing member 9, and It is formed to have an inward taper shape from the portion 9e toward the tip side. And the front-end | tip part 9c is formed in the substantially wedge shape which was sharp.

この図１０の実施形態においても、根鉢用接触体固定部材９の両側の先端部９ｃが略楔形に形成されているので、根鉢用接触体固定部材９を根鉢の側面に容易に打ち込むことができる。また、それぞれ３つの三角形の両側の頂角の部分９ｅが根鉢用接触体固定部材９の側片９ｂの外面より外側に突出して形成されているので、根鉢用接触体固定部材９が一旦根鉢８の側面８ａに打ち込まれた後は、前記側片９ｂの外面より外側に突出した頂角の部分９ｅが抵抗力として作用して根鉢用接触体固定部材９が根鉢の側面から不用意に抜け出るのが好適に防止されることとなる。特に、この図１０の実施形態においては、３つの三角形が長さ方向に連続するような釘状に形成されているので、側片９ｂの外面より外側に突出した頂角の部分９ｅは、図１０に示すように全部で１２個形成されていることになり、従って、根鉢用接触体固定部材９が一旦根鉢８の側面８ａに打ち込まれた後の抜け止め防止効果は、一層良好となる。   Also in the embodiment of FIG. 10, since the tip portions 9c on both sides of the root pot contact body fixing member 9 are formed in a substantially wedge shape, the root pot contact body fixing member 9 is easily driven into the side face of the root pot. be able to. Further, the apex angle portions 9e on both sides of each of the three triangles are formed so as to protrude outward from the outer surface of the side piece 9b of the root pot contact body fixing member 9, so that the root pot contact body fixing member 9 is temporarily provided. After being driven into the side surface 8a of the root pot 8, the apex angle portion 9e protruding outward from the outer surface of the side piece 9b acts as a resistance force so that the root pot contact body fixing member 9 is removed from the side surface of the root pot. Inadvertent escape is preferably prevented. In particular, in the embodiment of FIG. 10, since the three triangles are formed in a nail shape that continues in the length direction, the apex angle portion 9e protruding outward from the outer surface of the side piece 9b is shown in FIG. As shown in FIG. 10, twelve pieces are formed in total, and therefore, the effect of preventing the removal after the root pot contact body fixing member 9 is once driven into the side surface 8 a of the root pot 8 is further improved. Become.

さらに、根鉢用接触体固定部材９として、図１１に示すように、２枚の板状部材１２、１２が、それぞれ回動自在となるようにピン１３で軸支されて構成されたものを用いることもできる。２枚の板状部材１２の先端部１２ａは、尖った形状に形成されている。この図１１の実施形態の根鉢用接触体固定部材９は、たとえば上記図３及び図４に示すような、肩パットと称される根鉢８の肩部８ｂに接触されるような根鉢用接触体１に適用されうる。具体的には、根鉢用接触体１の孔４に根鉢用接触体固定部材９が挿入されるようにして、該根鉢用接触体固定部材９が根鉢８の肩部８ｂに打ち込まれる。   Further, as the root pot contact body fixing member 9, as shown in FIG. 11, two plate-like members 12, 12 are each configured to be pivotally supported by a pin 13 so as to be rotatable. It can also be used. The tip portions 12a of the two plate-like members 12 are formed in a sharp shape. The root pot contact body fixing member 9 of the embodiment of FIG. 11 is a root pot that is in contact with a shoulder portion 8b of a root pot 8 called a shoulder pad, for example, as shown in FIGS. It can be applied to the contact body 1 for use. Specifically, the root pot contact body fixing member 9 is inserted into the hole 4 of the root pot contact body 1 so that the root pot contact body fixing member 9 is driven into the shoulder 8 b of the root pot 8. It is.

この図１１の実施形態においては、根鉢用接触体固定部材９が根鉢８の肩部８ｂに打ち込まれる際に、図１２に示すように、尖った先端部１２ａとは反対側の部分を同図の矢印方向にハンマー等で打設することにより、２枚の板状部材１２、１２がそれぞれピン１３を中心として外向きに少し回動し、２枚の板状部材１２、１２がそれぞれ開いたような状態にされて根鉢用接触体固定部材９が根鉢８の肩部８ｂに打ち込まれることとなる。このように２枚の板状部材１２、１２がそれぞれ開いたような状態にされて根鉢用接触体固定部材９が根鉢８の肩部８ｂに打ち込まれるので、開かれた板状部材１２、１２が抵抗力として作用して根鉢用接触体固定部材９が根鉢８の肩部８ｂから不用意に抜け出るのが好適に防止されることとなる。   In the embodiment of FIG. 11, when the root pot contact body fixing member 9 is driven into the shoulder portion 8b of the root pot 8, as shown in FIG. By placing a hammer or the like in the direction of the arrow in the figure, the two plate-like members 12 and 12 are slightly rotated outward about the pin 13 respectively, and the two plate-like members 12 and 12 are respectively The root pot contact body fixing member 9 is driven into the shoulder portion 8 b of the root pot 8 in an open state. Since the two plate-like members 12 and 12 are thus opened and the root pot contact body fixing member 9 is driven into the shoulder portion 8b of the root pot 8, the opened plate-like member 12 is opened. , 12 acts as a resistance force, and the root pot contact body fixing member 9 is preferably prevented from inadvertently coming out of the shoulder portion 8b of the root pot 8.

さらに、根鉢用接触体固定部材９として、図１３に示すように、棒状体が側面略コ字状となるように形成された２つの側片９ｂが、１つの棒状体９ｆで連結されたように形成されたものを用いることもできる。この図１３の実施形態では、図５乃至図１２の実施形態のように、根鉢用接触体固定部材９が板状の部材で形成されているのではなく、棒状の部材で形成されているので、根鉢用接触体固定部材９を形成する材料を節減することができるという利点がある。   Furthermore, as shown in FIG. 13, as the root pot contact body fixing member 9, two side pieces 9b formed so that the rod-like body has a substantially U-shaped side surface are connected by one rod-like body 9f. What was formed in this way can also be used. In the embodiment of FIG. 13, the root pot contact body fixing member 9 is not formed of a plate-like member as in the embodiments of FIGS. 5 to 12, but is formed of a rod-like member. Therefore, there is an advantage that the material forming the root pot contact body fixing member 9 can be saved.

さらに、根鉢用接触体固定部材９として、図１４に示すように、ボルト状に形成された根鉢用接触体固定部材９を用いることもできる。この場合には、該ボルト状の根鉢用接触体固定部材９に螺合できるようなナット状部材１４が、根鉢用接触体１に取り付けられることになり、図１５のようにボルト状の根鉢用接触体固定部材９がナット状部材１４に螺合されることによって、根鉢用接触体固定部材９と根鉢用接触体１との相互間が固定されることになる。この図１４の実施形態では、根鉢用接触体固定部材９がハンマー等で根鉢８に打ち込まれるわけではないが、ボルト状の根鉢用接触体固定部材９がナット状部材１４に螺合されることによって、結果的に根鉢用接触体固定部材９が根鉢８に食い込むことになる。また、この図１４の実施形態では、汎用性のあるボルト状の部材を根鉢用接触体固定部材９として用いることができるので、根鉢用接触体固定部材の準備のためのコストを節減することができるという利点がある。   Furthermore, as the root pot contact body fixing member 9, as shown in FIG. 14, a root pot contact body fixing member 9 formed in a bolt shape may be used. In this case, a nut-like member 14 that can be screwed to the bolt-shaped root-pot contact body fixing member 9 is attached to the root-basket contact body 1, and the bolt-like shape as shown in FIG. When the root pot contact body fixing member 9 is screwed into the nut-like member 14, the root pot contact body fixing member 9 and the root pot contact body 1 are fixed to each other. In the embodiment of FIG. 14, the root pot contact body fixing member 9 is not driven into the root pot 8 with a hammer or the like, but the bolt-shaped root pot contact body fixing member 9 is screwed onto the nut member 14. As a result, the root pot contact body fixing member 9 bites into the root pot 8 as a result. Further, in the embodiment of FIG. 14, a versatile bolt-shaped member can be used as the root pot contact body fixing member 9, thereby reducing the cost for preparing the root pot contact body fixing member. There is an advantage that you can.

本実施形態の根鉢用固定用具には、上記のような複数の根鉢用接触体１と、複数の根鉢用接触体固定部材９の他に、樹木の幹部の周囲に配置されて、前記複数の根鉢用接触体１に掛け回される支持ベルトがさらに具備されていてもよい。根鉢用接触体には、支持ベルトが直接掛け回されていてもよく、また別の部材を介して間接的に掛け回されていてもよい。いずれの場合でも、支持ベルトが締め付けられることで該支持ベルトに緊締力が生じると、根鉢に対して根鉢用接触体の押圧力が作用することとなる。このような支持ベルトを用いる場合、１本の支持ベルトを複数個の根鉢用接触体１に架け回すことも可能であるが、これに限らず、たとえば樹木の根元部に支持リングを巻装させ、その支持リングと根鉢用接触体１とに支持ベルトを１本ずつ架け渡して支持することも可能である。   In the root pot fixing tool of the present embodiment, in addition to the plurality of root pot contact bodies 1 and the plurality of root pot contact body fixing members 9, the root pot fixing tool is arranged around the trunk of the tree, A support belt that is wound around the plurality of root pot contact bodies 1 may be further provided. A support belt may be directly wound around the root pot contact body, or may be indirectly wound around another member. In any case, when a tightening force is generated on the support belt by tightening the support belt, the pressing force of the root pot contactor acts on the root pot. When such a support belt is used, it is possible to wrap one support belt around a plurality of root pot contact bodies 1, but not limited to this, for example, a support ring is wound around the root of a tree. It is also possible to support the support ring and the root pot contact body 1 by suspending one support belt at a time.

また本実施形態の根鉢用固定用具には、根鉢を載置するための根鉢用載置体１５がさらに具備されていてもよい。根鉢用載置体１５としては、たとえば図１６及び図１７に示すように、根鉢の直接的な載置部分となる固定部材１６と、該固定部材１６に対して移動可能に構成された移動部材１７とで構成されたようなものを用いることができる。   The root pot fixing tool of this embodiment may further include a root pot mounting body 15 for mounting the root pot. As shown in FIGS. 16 and 17, for example, as shown in FIGS. 16 and 17, the root pot mounting body 15 is configured to be movable with respect to the fixing member 16 serving as a direct mounting portion of the root pot and the fixing member 16. The thing comprised with the moving member 17 can be used.

この固定部材１６としては、たとえば図１６、図１７、図１８のように、断面四角形状の細長い四角筒状に形成された２本の枠杆１８、１８を平面略十字状に交差させて形成されたようなものを用いることができる。また、このような平面略十字状のものに限らず、３本の枠杆１８、或いは４本の枠杆１８が、中央で交差するように構成されたものを用いることも可能である。さらに、固定部材１６の２本の枠杆１７、１７が交差されて根鉢用載置体１が形成されているものの他、根鉢用載置体１は、たとえば４本の枠杆で平面略四角形状に形成されたものであってもよく、また３本の枠杆で平面略三角形状に形成されたものであってもよい。   For example, as shown in FIGS. 16, 17, and 18, the fixing member 16 is formed by intersecting two frame rods 18 and 18 formed in an elongated rectangular tube shape having a quadrangular cross section in a plane substantially cross shape. Can be used. Moreover, it is not limited to such a substantially plane cross shape, and it is also possible to use a structure in which three frame rods 18 or four frame rods 18 intersect at the center. Further, in addition to the one in which the two frame rods 17, 17 of the fixing member 16 are intersected to form the root pot mounting body 1, the root pot mounting body 1 is a flat surface with, for example, four frame rods. It may be formed in a substantially square shape, or may be formed in a plane substantially triangular shape with three frame rods.

また移動部材１７としては、たとえば図１６、図１７、図１８のように、前記固定部材１６の枠杆１８にスライド自在に外嵌合され、該枠杆１８と同様に断面四角形状の細長い四角筒状に形成されたスライド杆１９と、該スライド杆１９の先端側に取り付けられた打込部材２０とからなるものを用いることができる。打込部材２０は、図１６及び図１７に示すように、２つの直角部分２０ａ、２０ａと、２つの鈍角部分２０ｂ、２０ｂと、１つの鋭角部分２０ｃとからなり、その１つの鋭角部分２０ｃが先端側とされて、該先端側の鋭角部分２０ｃによって、根鉢が収納される植穴の側壁面に打ち込み可能となるように構成されている。   As the moving member 17, for example, as shown in FIGS. 16, 17, and 18, the movable member 17 is slidably fitted to a frame rod 18 of the fixed member 16, and is elongated rectangular with a rectangular cross section like the frame rod 18. What consists of the slide rod 19 formed in the cylinder shape and the driving | running | working member 20 attached to the front end side of this slide rod 19 can be used. As shown in FIGS. 16 and 17, the driving member 20 includes two right angle portions 20a and 20a, two obtuse angle portions 20b and 20b, and one acute angle portion 20c. The distal end side is configured to be driven into the side wall surface of the planting hole in which the root pot is accommodated by the acute angle portion 20c on the distal end side.

さらに、この打込部材２０は板状に形成されており、植穴の底面に載置された際に、その植穴の底面における土に対して抵抗を生じさせるような機能をも奏するものである。さらに、前記スライド杆１９と打込部材２０との連設部分には、図１９に示すようにハンマーで打設するための打設体２１が上向きに突設されている。   Further, the driving member 20 is formed in a plate shape, and when it is placed on the bottom surface of the planting hole, it also has a function of causing resistance to the soil on the bottom surface of the planting hole. is there. Further, at a connecting portion between the slide rod 19 and the driving member 20, a driving body 21 for driving with a hammer is projected upward as shown in FIG.

また、上記のような根鉢用載置体１５に根鉢８が載置される場合には、連結用部材が根鉢用接触体１と根鉢用載置体１５とに連結されることが望ましい。このような連結用部材としては、たとえば、図２０及び図２１に示すアジャスターのようなものを用いることができる。このアジャスター２２は、根鉢用載置体１５に対する根鉢用接触体１の位置を調整することにより、根鉢の大きさに合わせて根鉢用接触体１を根鉢に接触させることができるようにするためのものである。このアジャスター２２は、図２０及び図２１に示すように、前記固定部材１６の枠杆１８に外嵌できるような大きさの円筒状に形成されたアジャスター軸部２３と、該アジャスター軸部２３に固着されたアジャスターフレーム２４とで構成されている。   Further, when the root pot 8 is placed on the root pot mounting body 15 as described above, the connecting member is connected to the root pot contact body 1 and the root pot mounting body 15. Is desirable. As such a connecting member, for example, an adjuster shown in FIGS. 20 and 21 can be used. The adjuster 22 can bring the root pot contact body 1 into contact with the root pot according to the size of the root pot by adjusting the position of the root pot contact body 1 with respect to the root pot mounting body 15. It is for doing so. As shown in FIGS. 20 and 21, the adjuster 22 includes an adjuster shaft portion 23 formed in a cylindrical shape having a size that can be fitted onto the frame rod 18 of the fixing member 16, and an adjuster shaft portion 23. It is comprised with the adjuster frame 24 to which it adhered.

このアジャスターフレーム２４は、細い鋼材が底部２４ａで折り曲げられ、その折り曲げられた底部２４ａが前記アジャスター軸部２３の外周に沿って固着され、且つ該アジャスター軸部２３から１対の鋼材部分が平行に配置されるように構成されている。そして、該アジャスターフレーム２４の１対の鋼材部分の上部には、板状部材を折り曲げて形成した係止片２５が形成されている。この折り曲げられた係止片２５は、幅の異なる長片２５ａと短片２５ｂとからなり、その係止片２５の略中央にはボルト２６が前記短片２５ｂ側から長片２５ａ側に挿通されるように止着されている。   In the adjuster frame 24, a thin steel material is bent at the bottom portion 24a, the bent bottom portion 24a is fixed along the outer periphery of the adjuster shaft portion 23, and a pair of steel material portions are parallel to the adjuster shaft portion 23. It is configured to be arranged. A locking piece 25 formed by bending a plate-like member is formed on the upper part of the pair of steel parts of the adjuster frame 24. The bent locking piece 25 is composed of a long piece 25a and a short piece 25b having different widths, and a bolt 26 is inserted from the short piece 25b side to the long piece 25a side at the approximate center of the locking piece 25. It is fixed to.

また、このように根鉢用載置体１５に対する根鉢用接触体１の位置を調整することができるアジャスター２２以外に、位置を調整することができない連結用部材を用いることも可能である。   Further, in addition to the adjuster 22 that can adjust the position of the root pot contact body 1 with respect to the root pot mounting body 15 as described above, a connecting member whose position cannot be adjusted can be used.

さらに、上記根鉢用載置体１５には、前記根鉢８の底部８ｃに食い込む根鉢底部固定部材２７が設けられていてもよい。このような根鉢底部固定部材２７が設けられている場合には、根鉢用載置体１５に根鉢８を載置する際、根鉢８の底部８ｃに根鉢底部固定部材２７が突き刺さることとなり、このような根鉢底部固定部材２７の根鉢８の底部８ｃに対する食い込み力と、上記のような根鉢用接触体固定部材９の根鉢外周面への打ち込みによる食い込み力との双方によって、根鉢をより確実に固定することができ、地盤沈下が生じた場合や樹木に傾倒力が作用する場合における、鉛直方向に対する根鉢の傾きをより好適に防止することができる。ここで、地盤沈下が生じた場合や樹木に傾倒力が作用する場合における、鉛直方向に対する根鉢の傾きを好適に防止するためには、根鉢底部固定部材２７は根鉢８の底部８ｃの中央付近に食い込ませることが望ましい。   Further, the root pot mounting body 15 may be provided with a root pot bottom fixing member 27 that bites into the bottom 8 c of the root pot 8. In the case where such a root pot bottom fixing member 27 is provided, when the root pot 8 is placed on the root pot mounting body 15, the root pot bottom fixing member 27 pierces the bottom 8 c of the root pot 8. That is, both the biting force of the root pot bottom fixing member 27 with respect to the bottom 8c of the root pot 8 and the biting force due to driving of the root pot contact body fixing member 9 into the root pot outer peripheral surface as described above. Thus, the root pot can be more reliably fixed, and the inclination of the root pot relative to the vertical direction can be more suitably prevented when ground subsidence occurs or when a tilting force acts on the tree. Here, in order to suitably prevent the inclination of the root pot with respect to the vertical direction when the ground subsidence occurs or when the tilting force acts on the tree, the root pot bottom fixing member 27 is formed on the bottom 8c of the root pot 8.

次に、本実施形態の樹木の支持施工方法は、上記のように、樹木の根鉢に根鉢用接触体を接触させ、該根鉢用接触体で根鉢を押圧して該根鉢を固定することにより樹木を支持施工する樹木の支持施工方法において、前記根鉢に根鉢用接触体を接触させた状態で該根鉢用接触体を外側から保持するための根鉢用接触体固定部材を前記根鉢に食い込ませ、該根鉢用接触体固定部材で前記根鉢用接触体を根鉢に固定するものである。   Next, as described above, the method for supporting and supporting the tree according to the present embodiment contacts the root pot with the root pot of the tree, and fixes the root pot by pressing the root pot with the root pot contact body. In the tree support construction method, the root pot contact body fixing member for holding the root pot contact body from the outside in a state where the root pot contact body is in contact with the root pot. Is rooted in the root pot, and the root pot contact body is fixed to the root pot by the root pot contact body fixing member.

根鉢の周囲に根鉢用接触体を複数配置し、一つの根鉢用接触体と他の根鉢用接触体との間に支持ベルトを掛け回した状態で該支持ベルトを締め付けることによって前記根鉢用接触体で根鉢を押圧した後に、前記根鉢用接触体固定部材を、前記根鉢用接触体の外側から保持しつつ根鉢に打ち込むことも可能である。   A plurality of root pot contact bodies are arranged around the root pot, and the support belt is tightened in a state where the support belt is hung between one root pot contact body and another root pot contact body. After pressing the root pot with the root pot contact body, the root pot contact body fixing member can be driven into the root pot while being held from the outside of the root pot contact body.

このような支持ベルトが複数の根鉢用接触体に掛け回され、支持ベルトが締め付けられることで該支持ベルトに緊締力が生じると、根鉢に対して根鉢用接触体の押圧力が作用することとなる。そして、上記のように支持ベルトを締め付けることによって前記根鉢用接触体で根鉢を押圧した後に、根鉢用接触体固定部材が根鉢用接触体を外側から保持しつつ根鉢に食い込むことで、根鉢に対する根鉢用接触体の位置ずれがより確実に防止されることとなる。この結果、根鉢に対する根鉢用接触体の押圧力の低下をより好適に防止できることとなり、根鉢を固定する効果がより向上することとなる。   When such a support belt is wound around a plurality of root pot contact bodies and a tightening force is generated on the support belt by tightening the support belt, the pressing force of the root pot contact body acts on the root pot. Will be. Then, after pressing the root pot with the root pot contact body by tightening the support belt as described above, the root pot contact body fixing member bites into the root pot while holding the root pot contact body from the outside. Thus, the positional deviation of the root pot contact body with respect to the root pot is more reliably prevented. As a result, it is possible to more suitably prevent the pressing force of the root pot contactor against the root pot, and the effect of fixing the root pot is further improved.

尚、上記のような支持ベルトを複数の根鉢用接触体に掛け回す工程は、根鉢用接触体固定部材を、根鉢用接触体の外側から保持しつつ根鉢に打ち込む工程の後の行うことも可能ではあるが、上記のように、支持ベルトの緊締力による根鉢用接触体の根鉢に対する押圧力を損なわないようにしつつ、根鉢用接触体固定部材が根鉢用接触体を外側から保持しつつ根鉢に打ち込まれることによる根鉢に対する根鉢用接触体の押圧力と、上記根鉢用接触体固定部材が根鉢に打ち込まれることによる食い込み力を好適に生じさせるためには、根鉢用接触体固定部材を、根鉢用接触体の外側から保持しつつ根鉢に打ち込む工程の前に、支持ベルトを複数の根鉢用接触体に掛け回して緊締させることを行うのが望ましい。   In addition, the process of hanging the support belt as described above around a plurality of contact bodies for root pots is performed after the process of driving into the root pot while holding the contact body fixing member for root pots from the outside of the contact body for root pots. Although it is possible to perform, as described above, the root pot contact body fixing member is the root pot contact body while maintaining the pressing force against the root pot of the root pot contact body by the tightening force of the support belt. In order to suitably generate the pressing force of the root pot contact body against the root pot by being driven into the root pot while holding the root from the outside and the biting force due to the root pot contact body fixing member being driven into the root pot. In order to do this, before the step of driving the root pot contact body fixing member into the root pot while holding it from the outside of the root pot contact body, the support belt is hung around a plurality of root pot contact bodies and tightened. It is desirable to do it.

また、樹木の根鉢の外周面に、複数の根鉢用接触体を接触させる工程の前に、根鉢を載置するための根鉢用載置体を地面に設置し、該根鉢用載置体上に根鉢を載置する工程をさらに含むことも可能である。   Further, before the step of bringing a plurality of root pot contact bodies into contact with the outer peripheral surface of a tree root pot, a root pot mounting body for mounting the root pot is installed on the ground, and the root pot mounting is mounted. It is possible to further include a step of placing a root pot on the body.

このような根鉢用載置体が用いられる場合には、複数の根鉢用接触体を接触させる工程の後に、複数の根鉢用接触体と、根鉢用載置体とを、連結用部材によって連結する工程をさらに含むことができる。   When such a root pot mounting body is used, a plurality of root pot contact bodies and a root pot mounting body are connected to each other after the step of contacting the plurality of root pot contact bodies. The method may further include connecting with a member.

また、上記のような根鉢用載置体を用いずに、地面に打ち込み可能な打込杆を用い、該打込杆を根鉢の周囲の地面に打ち込み、打ち込まれた打込杆に連結用部材を介して根鉢用接触体を連結することもできる。この場合においても、根鉢用接触体に、上記のような支持ベルトを掛け回して緊締させることができる。   Moreover, without using the root pot mounting body as described above, a driving rod that can be driven into the ground is used, and the driving rod is driven into the ground around the root pot and connected to the driven driving rod. It is also possible to connect the root pot contact body through the member. Even in this case, the support belt as described above can be wound around the root pot contact body and tightened.

尚、本実施形態の樹木の支持施工方法は、植穴内に根鉢を埋め、土で閉塞して樹木を支持する、いわゆる地下支柱の施工を行う場合に適用される他、たとえば屋上庭園における樹木の支持施工に本発明を適用することも可能である。また一般の地盤の他、人工地盤における樹木の支持施工に本発明を適用することも可能である。   Note that the tree support construction method of this embodiment is applied to the construction of a so-called underground strut in which a root pot is buried in a planting hole and closed with soil to support the tree, for example, a tree in a roof garden It is also possible to apply the present invention to the supporting construction.

ウインチ４８は、図３１及び図３２に示すように、支持ベルト４２の端部を取り付ける軸部５０を具備し、さらに該軸部５０の側部に設けられたラチェット５１と、該ラチェット５１に係止可能な係止体５２とを具備して構成されている。   As shown in FIGS. 31 and 32, the winch 48 includes a shaft portion 50 to which an end portion of the support belt 42 is attached, a ratchet 51 provided on a side portion of the shaft portion 50, and the ratchet 51. The latching body 52 which can be stopped is comprised and comprised.

このようなウインチ４８と、支持ベルト４２の取付金具４４とが、図３３及び図３４に示すように根鉢用接触体１に取り付けられる。この場合、ウインチ４８と４４とは、図３３に示すように、相互に約９０度の角度をなすように、ボルト４９で同軸的に根鉢用接触体１に取り付けられる。そして、ウインチ４８の端部４８ａが根鉢用接触体１を押さえ付けることとなる。そして、ボルト４９が孔７に挿入されて、取付金具４４とウインチ４８とが根鉢用接触体１に取り付けられた状態において、取付金具４４は左右に可動しうるように構成されている。これによって、ウインチ４８の締付力が、該ウインチ４８側に取り付けられた支持ベルト４２の端部のみならず、取付金具４４側に取り付けられた支持ベルト４２の端部にも好適に作用することとなり、支持ベルト４２の張力が好適に生じることとなるのである。   Such a winch 48 and the mounting bracket 44 of the support belt 42 are attached to the root pot contact body 1 as shown in FIGS. 33 and 34. In this case, as shown in FIG. 33, the winches 48 and 44 are coaxially attached to the root pot contact body 1 with bolts 49 so as to form an angle of about 90 degrees. And the edge part 48a of the winch 48 will press down the contact body 1 for root pots. Then, in a state where the bolt 49 is inserted into the hole 7 and the mounting bracket 44 and the winch 48 are mounted on the root pot contact body 1, the mounting bracket 44 is configured to be movable left and right. Thereby, the tightening force of the winch 48 preferably acts not only on the end of the support belt 42 attached to the winch 48 side but also on the end of the support belt 42 attached to the mounting bracket 44 side. Thus, the tension of the support belt 42 is suitably generated.

この支持ベルト４２の素材としては、年月の経過に伴って分解する素材、たとえば生分解樹脂、その他、麻、綿、ジュート等の素材を用いることができる。生分解樹脂としては、ポリ乳酸、ポリブチレンサクシネート等の材質のものを用いることができる。また支持ベルト４２の素材の形態としては、上記生分解樹脂からなる糸であって、たとえばテグス等に用いられるような糸を編成又は織成されたような形態のものを用いることができる。この場合、この支持ベルト４２の全体を上記のような分解性の素材で構成してもよいが、本実施形態では、図３０に示すように、取付金具４４の長孔４６に挿入される部分となる先端部４５のみが分解性の素材で構成されており、それ以外のベルトボディ４３の部分は、たとえば一般の合成樹脂製素材のように分解しにくい素材のものを用いてもよい。このように構成することで、たとえば支持ベルト４２の先端部４５は比較的高価な生分解樹脂で構成し、先端部４５以外の部分を比較的安価な汎用性の合成樹脂で構成し、全体のコストを低減することが可能となる。   As a material of the support belt 42, a material that decomposes with the passage of time, for example, a biodegradable resin, a material such as hemp, cotton, jute, or the like can be used. As the biodegradable resin, a material such as polylactic acid or polybutylene succinate can be used. Moreover, as a form of the material of the support belt 42, it is possible to use a thread made of the above-described biodegradable resin, such as a form in which a thread used for, for example, Tegus is knitted or woven. In this case, the entire support belt 42 may be made of the degradable material as described above, but in this embodiment, as shown in FIG. 30, the portion inserted into the elongated hole 46 of the mounting bracket 44. Only the leading end 45 is made of a degradable material, and the other belt body 43 may be made of a material that is difficult to be decomposed, such as a general synthetic resin material. By configuring in this way, for example, the tip 45 of the support belt 42 is made of a relatively expensive biodegradable resin, and the parts other than the tip 45 are made of a relatively inexpensive general-purpose synthetic resin. Costs can be reduced.

次に、上記のような構成からなる根鉢用固定用具を用いて樹木の支持施工を行う樹木の支持施工方法の実施形態について説明する。上記のような根鉢用固定用具は、植穴の底壁面に設置して使用されるものである。そして、上記のような各構成部材によって根鉢用固定用具が組み立てられる。   Next, an embodiment of a tree support construction method for supporting a tree using the root pot fixing tool having the above-described configuration will be described. The root pot fixing tool as described above is used by being installed on the bottom wall surface of the planting hole. Then, the root pot fixing tool is assembled by the respective constituent members as described above.

すなわち、前記スライド杆１９が枠杆１８に挿入されることによって、移動部材１７が固定部材１６に一体化されて根鉢用載置体１５が形成され、さらに図３５に示すようにアジャスター軸部２３が移動部材１７のスライド杆１９に外嵌されることによって、アジャスター２２が前記根鉢用載置体１５に連結される。このようにして４個のアジャスター２２が図３６及び図３７のように移動部材１７に取り付けられて該移動部材１７上に立設されることとなる。   That is, when the slide rod 19 is inserted into the frame rod 18, the moving member 17 is integrated with the fixed member 16 to form the root pot placement body 15, and further, as shown in FIG. The adjuster 22 is coupled to the root pot mounting body 15 by 23 being externally fitted to the slide rod 19 of the moving member 17. In this way, the four adjusters 22 are attached to the moving member 17 as shown in FIGS. 36 and 37 and are erected on the moving member 17.

このようにして組み立てられた根鉢用固定用具が植穴の底壁面に設置された状態で、打込部材２０を植穴の側壁面に打ち込む。この打ち込みは、打設体２１をハンマーで打設することによって行う。この場合において、本実施形態では、図３６及び図３７に示すように、アジャスター２２が根鉢用載置体１５の移動部材１７のスライド杆１９上に立設され、また前記打設体２１はスライド杆１９の先端側に設けられているため、この打設体２１をハンマーで打設する作業を行う場合、前記根鉢用接触体１が立設されているアジャスター２２の存在が支障となって、ハンマーでの打設作業が行いにくくなる。   With the root pot fixing tool assembled in this manner installed on the bottom wall surface of the planting hole, the driving member 20 is driven into the side wall surface of the planting hole. This driving is performed by driving the driving body 21 with a hammer. In this case, in this embodiment, as shown in FIGS. 36 and 37, the adjuster 22 is erected on the slide rod 19 of the moving member 17 of the root pot mounting body 15, and the placing body 21 is Since it is provided on the distal end side of the slide rod 19, the presence of the adjuster 22 on which the root pot contact body 1 is erected becomes an obstacle when the operation of placing the placing body 21 with a hammer is performed. This makes it difficult to perform a hammering operation.

しかしながら、本実施形態のアジャスター２２は、略円筒状のアジャスター軸部２３に、１対の鋼材部分が平行に配置されるようなアジャスターフレーム２４が固着されて構成されたものであり、そのアジャスター軸部２３が移動部材１７のスライド杆１９に外嵌されて構成されたものであるため、図３８に示すように、アジャスター軸部２３を中心として、アジャスターフレーム２４をスライド杆１９に対して横向きに回動させることが可能となる。この結果、ハンマーで打設体２１を打設する作業を行う場合、前記アジャスター２２が支障となることがなく、打設体２１の打設作業を容易に行うことができる。これによって、図３９に示すように打込部材２０を植穴５３の側壁面５４に容易に打ち込むことができるのである。   However, the adjuster 22 of the present embodiment is configured by fixing an adjuster frame 24 in which a pair of steel parts are arranged in parallel to a substantially cylindrical adjuster shaft portion 23, and the adjuster shaft Since the portion 23 is externally fitted to the slide rod 19 of the moving member 17, as shown in FIG. 38, the adjuster frame 24 is placed sideways with respect to the slide rod 19 around the adjuster shaft portion 23. It can be rotated. As a result, when performing the operation of placing the placing body 21 with a hammer, the adjuster 22 is not hindered, and the placing work of the placing body 21 can be easily performed. As a result, the driving member 20 can be easily driven into the side wall surface 54 of the planting hole 53 as shown in FIG.

次に、上記のようにして、打込部材２０を植穴５３の側壁面５４に打ち込んだ後、アジャスター２２のアジャスターフレーム２４を逆方向に回動させて再度スライド杆１９上に起立させ、その状態で図４０に示すようにアジャスター２２に根鉢用接触体１を取り付ける。より具体的には、アジャスターフレーム２４の上部に取り付けられた係止片２５を、接触体中央片２における２個の孔４ｂ、４ｂに跨がるようにして前記根鉢用接触体１の背面側に係止させる。本実施形態では、計６個の孔のうち、上から４番目の孔４ｂと５番目の孔４ｂとに跨がるようにアジャスター２２の係止片２５が係止される。ただし、何番目の孔４ｂに跨がるようにアジャスター２２の係止片２５を係止させるかは任意に変更可能であり、係止片２５を係止させる孔４ｂの位置によって、根鉢用接触体１の高さが変わることになる。従って、支持する根鉢の高さに応じて根鉢用接触体１の高さを調節することができる。   Next, after driving the driving member 20 into the side wall surface 54 of the planting hole 53 as described above, the adjuster frame 24 of the adjuster 22 is rotated in the reverse direction to stand on the slide rod 19 again. In the state, the root pot contact body 1 is attached to the adjuster 22 as shown in FIG. More specifically, the back surface of the root pot contact body 1 is arranged so that the locking piece 25 attached to the upper part of the adjuster frame 24 straddles the two holes 4b and 4b in the contact body center piece 2. Lock to the side. In the present embodiment, the locking piece 25 of the adjuster 22 is locked so as to straddle the fourth hole 4b and the fifth hole 4b from the top among the six holes in total. However, it can be arbitrarily changed whether the locking piece 25 of the adjuster 22 is locked so as to straddle the hole 4b. Depending on the position of the hole 4b for locking the locking piece 25, the root pot The height of the contact body 1 will change. Therefore, the height of the root pot contact body 1 can be adjusted according to the height of the root pot to be supported.

さらにボルト２６を係止片２５に挿通することによって、孔４ｂ、４ｂに跨がって係止されている係止片２５が接触体中央片２から離脱するのが禁止される。これによって、図４０に示すように、根鉢用接触体１がアジャスター２２に連結されることとなる。そして、図４１に示すように、４個の根鉢用接触体１をすべてアジャスター２２のアジャスターフレーム２４に取り付ける。   Further, by inserting the bolt 26 into the locking piece 25, the locking piece 25 locked across the holes 4b and 4b is prohibited from being detached from the contact body central piece 2. As a result, as shown in FIG. 40, the root pot contact body 1 is connected to the adjuster 22. Then, as shown in FIG. 41, the four root pot contacts 1 are all attached to the adjuster frame 24 of the adjuster 22.

次に、上記のようにして、根鉢用接触体１をアジャスター２２に取り付けた後、根鉢８を根鉢用載置体１５に載置する。この場合、根鉢用接触体１は、図４２に示すようにアジャスター２２とともに、予め傾倒させておく。すなわち、上述のようにアジャスター２２のアジャスター軸部２３を中心に、アジャスターフレーム２４を回動させることができるので、根鉢用接触体１もアジャスター２２とともに傾倒させることができるのである。このようにアジャスター２２のアジャスターフレーム２４をスライド杆１９に対して横向きに回動させて傾倒させることにより、根鉢８を根鉢用載置体１５に載置する作業にも支障を生じさせないこととなる。   Next, after attaching the root pot contact body 1 to the adjuster 22 as described above, the root pot 8 is mounted on the root pot mounting body 15. In this case, the root pot contact body 1 is previously tilted together with the adjuster 22 as shown in FIG. That is, since the adjuster frame 24 can be rotated around the adjuster shaft portion 23 of the adjuster 22 as described above, the root pot contact body 1 can also be tilted together with the adjuster 22. In this way, the adjuster frame 24 of the adjuster 22 is rotated laterally with respect to the slide rod 19 so as to be tilted, so that the work of placing the root pot 8 on the root pot mounting body 15 is not hindered. It becomes.

また、この場合において、根鉢８を根鉢用載置体１５に載置すると、図４３に示すように、根鉢底部固定部材２７が根鉢の底部に突き刺さる。より具体的には、根鉢底部固定部材２７の突片２９の山形状部３０が、根鉢８の底部８ｃに突き刺さって、根鉢底部固定部材２７が根鉢８の底部８ｃに食い込むこととなり、それによって、根鉢８が固定されることとなる。このように、根鉢底部固定部材２７が根鉢８の底部８ｃに食い込んで根鉢８が固定されることで、地盤沈下が生じた場合や樹木に傾倒力が作用する場合における、鉛直方向に対する根鉢８の傾きが防止される要因となる。   In this case, when the root pot 8 is placed on the root pot mounting body 15, as shown in FIG. 43, the root pot bottom fixing member 27 pierces the bottom of the root pot. More specifically, the mountain-shaped part 30 of the protruding piece 29 of the root pot bottom fixing member 27 pierces the bottom part 8c of the root pot 8, and the root pot bottom fixing member 27 bites into the bottom part 8c of the root pot 8. Thereby, the root pot 8 is fixed. Thus, the root pot bottom fixing member 27 bites into the bottom 8c of the root pot 8 and the root pot 8 is fixed, so that when the land subsidence occurs or when a tilting force acts on the tree, It becomes a factor by which the inclination of the root pot 8 is prevented.

次に、アジャスターフレーム２４を逆方向に回動させてアジャスター２２及び根鉢用接触体１を再度起立させる。この場合、アジャスター２２の位置は、図４４に示すように、根鉢８から離間するように設定されている。   Next, the adjuster frame 24 is rotated in the reverse direction, and the adjuster 22 and the root pot contact body 1 are erected again. In this case, the position of the adjuster 22 is set so as to be separated from the root pot 8 as shown in FIG.

そして、図４５に示すように、移動部材１７のスライド杆１９に沿ってアジャスター２２のアジャスター軸部２３を移動させることにより、根鉢用接触体１を根鉢８の側面８ａに接触させる。この場合において、アジャスター軸部２３は略円筒状に形成されたものであって、スライド杆１９に外嵌されているので、そのスライド杆１９上を容易に移動させることができる。また、アジャスター軸部２３が略円筒状に形成されているので、植穴５３の底部の地面との設置面積が少なく、アジャスター軸部２３をスライド杆１９に対してスライドさせる際の抵抗が少ないこととなり、この点でもアジャスター軸部２３を移動させる際の作業が容易となる。図４５には、４個の根鉢用接触体２をすべて根鉢８の側面８ａに当接した全体の状態を示している。   Then, as shown in FIG. 45, by moving the adjuster shaft portion 23 of the adjuster 22 along the slide rod 19 of the moving member 17, the root pot contact body 1 is brought into contact with the side surface 8 a of the root pot 8. In this case, the adjuster shaft portion 23 is formed in a substantially cylindrical shape and is externally fitted to the slide rod 19, so that it can be easily moved on the slide rod 19. Further, since the adjuster shaft portion 23 is formed in a substantially cylindrical shape, the installation area of the bottom of the planting hole 53 with the ground is small, and resistance when the adjuster shaft portion 23 is slid with respect to the slide rod 19 is small. In this respect, the work for moving the adjuster shaft 23 is facilitated. FIG. 45 shows an overall state in which all four root pot contact bodies 2 are in contact with the side surface 8 a of the root pot 8.

次に、図４６及び図４７に示すように、４個の根鉢用接触体１の掛止体５に支持ベルト４２を掛け回す。この場合、支持ベルト４２は前記のウインチ４８によって締め付ける。これによって、根鉢８の上面側が支持ベルト４２によって支持され、さらに支持ベルト４２の締付力によって、根鉢用接触体１が根鉢８側に押圧され、根鉢用接触体１がより確実に固定されることとなる。   Next, as shown in FIGS. 46 and 47, the support belt 42 is wound around the hooks 5 of the four root pot contacts 1. In this case, the support belt 42 is fastened by the winch 48 described above. As a result, the upper surface side of the root pot 8 is supported by the support belt 42, and the root pot contact body 1 is pressed against the root pot 8 side by the tightening force of the support belt 42, so that the root pot contact body 1 is more reliably secured. It will be fixed to.

次に、図７及び図８に示すように、根鉢用接触体固定部材９で根鉢用接触体１を保持させつつ、根鉢用接触体固定部材９を根鉢８の側面８ａに打ち込む。より具体的には、根鉢用接触体固定部材９の中央片９ａが、根鉢用接触体１の接触体頭部片３の頭部片下部３ｃの正面に接触し、根鉢用接触体固定部材９の両側片９ｂ、９ｂが前記接触体頭部片３の頭部片下部３ｃの両側に跨るように、根鉢用接触体固定部材９が根鉢８の側面８ａに打ち込まれることとなる。さらに、ボルト１１が根鉢用接触体固定部材９の孔１０に挿入されることによって、根鉢用接触体固定部材９と根鉢用接触体１との相互間が固定されることとなる。   Next, as shown in FIG. 7 and FIG. 8, the root pot contact body fixing member 9 is driven into the side surface 8 a of the root pot 8 while holding the root pot contact body 1 with the root pot contact body fixing member 9. . More specifically, the central piece 9a of the root pot contact body fixing member 9 contacts the front of the head piece lower part 3c of the contact body head piece 3 of the root pot contact body 1, and the root pot contact body. The root pot contact body fixing member 9 is driven into the side surface 8a of the root pot 8 so that both side pieces 9b, 9b of the fixing member 9 straddle both sides of the head piece lower portion 3c of the contact body head piece 3; Become. Further, the bolt 11 is inserted into the hole 10 of the root pot contact body fixing member 9 so that the root pot contact body fixing member 9 and the root pot contact body 1 are fixed to each other.

このような根鉢用接触体固定部材９は、図４８に示すように、４ケ所の根鉢用接触体１をそれぞれ保持するように、打ち込まれる。
このようにして根鉢用接触体固定部材９を根鉢８の側面８ａに打ち込むことによって、根鉢用接触体１が根鉢用接触体固定部材９に保持されて固定されることとなる。 As shown in FIG. 48, such root pot contact body fixing members 9 are driven so as to hold the four root pot contact bodies 1 respectively.
By driving the root pot contact body fixing member 9 into the side surface 8 a of the root pot 8 in this manner, the root pot contact body 1 is held and fixed by the root pot contact body fixing member 9.

このように根鉢用接触体１が根鉢用接触体固定部材９に保持、固定された状態で、根鉢用接触体固定部材９が根鉢８の側面８ａに打ち込まれることによって、根鉢８に対する根鉢用接触体１の位置ずれが防止されることとなり、また根鉢用接触体固定部材９が根鉢８に打ち込まれることによる食い込み力も根鉢に対して作用することになるので、地盤沈下が生じた場合や樹木に傾倒力が作用する場合における、鉛直方向に対する根鉢の傾きを、従来に比べてより確実に防止することが可能となる。   The root pot contact body fixing member 9 is driven into the side surface 8a of the root pot 8 in a state where the root pot contact body 1 is held and fixed to the root pot contact body fixing member 9 in this manner, thereby The positional displacement of the root pot contact body 1 with respect to 8 will be prevented, and the biting force due to the root pot contact body fixing member 9 being driven into the root pot 8 will also act on the root pot. It is possible to more reliably prevent the inclination of the root pot with respect to the vertical direction when ground subsidence occurs or when a tilting force acts on the tree as compared with the conventional case.

上記のように、根鉢用接触体１を外側から保持しつつ根鉢用接触体固定部材９を根鉢８の側面８ａに打ち込んだ後、植穴５３内に土を埋め、植穴を閉塞する。これによって樹木の支持施工が完了する。   As described above, the root pot contact body fixing member 9 is driven into the side surface 8a of the root pot 8 while holding the root pot contact body 1 from the outside, and then the soil is buried in the planting hole 53 to close the planting hole. To do. This completes the tree support construction.

上記のように、本実施形態では、前記根鉢用接触体固定部材９の作用と、前記根鉢底部固定部材２７の根鉢８の底部８ｃへの打ち込みの作用との双方の作用によって、地盤沈下が生じた場合や樹木に傾倒力が作用する場合における、鉛直方向に対する根鉢の傾きの防止効果が一層良好となる。   As described above, in the present embodiment, the ground is obtained by both the action of the root pot contact body fixing member 9 and the action of driving the root pot bottom fixing member 27 into the bottom 8c of the root pot 8. The effect of preventing the inclination of the root pot with respect to the vertical direction is further improved when subsidence occurs or when a tilting force acts on the tree.
