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。   The present invention relates to a method for supporting and constructing trees, and a root holder fixing tool used for such a method for supporting and supporting trees.

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 made as techniques for supporting and installing this type of tree. In the invention according to Patent Document 1, a plurality of fixing plates (contact members for root pot) are in contact with the circumferential surface of the root pot, and wires (support belts) are attached to the contact members for root pots, respectively. A pile is connected to the contact body for the root pot while being arranged around, and the pile is cast on the soil around the root pot, whereby the circumferential surface of the root pot is pressed by the contact body for the root pot, A tree will be supported and constructed by the contact body for the pot, 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。   In the invention according to Patent Document 2, a planting base (mounting base for root pot) is used in place of a pile driven in the surrounding soil of Patent Document 1 and a root pot is placed on the planting base. The connecting member is connected to the pressing plate (contact member for root bowl) and the planting base which are placed and brought into contact with the root bowl, and the connecting rope is disposed around the tree trunk via the connector to the pressing plate (Support belts) are connected, and trees will be supported and constructed by pressing plates, connecting ropes, and planting bases.

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 contact body for the root pot is in contact with the shoulder which is the boundary portion between the side surface and the upper surface of the root pot. Applications such as U.S. Pat. No. 5,677,067 are also made where the sides are contacted. The invention according to Patent Document 3 is in common with the invention according to Patent Document 1 and the invention according to Patent Document 2 in that a mounting body for a pot and a support belt are used together with the contact member for a root pot.

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 any of the inventions according to Patent Documents 1 to 3, the root pot is fixed by the tightening force of the support belt, the pressing force of the contact body for the root pot with the tightening of the support belt, etc. However, since the contact body for the root bowl is only in contact with the root bowl, when the ground on which the root bowl is placed settles down, for example, the wind exerts a tilting force on the tree. In such a case, there is a possibility that the contact object for root pot may be displaced from the position where it has been in contact with the base pot. And since the support belt will also be loosened when the contact body for root pots is displaced, the pressing force of the contact body for root pots with respect to the root pot is reduced. Essentially, the support belt is loosened simply by the occurrence of the above ground subsidence and the like, but in particular, the looseness of the support belt becomes more remarkable as the contact body for the root bowl is displaced, and accordingly, the part for the root pot The decrease in pressing force of the rootpiece contact body has been significant. For this reason, the root bowl 8 is not fixed reliably, and as a result, as shown to the dashed-two dotted line of FIG. 49, the problem that the root bowl 8 may incline with respect to the perpendicular direction arose.

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 problems, and it is possible to more securely fix the root basin as compared with the above-mentioned prior art, and in the case where ground subsidence has occurred or in the case of trees having a tilting force. An object of the present invention is to provide a method of supporting and supporting a tree capable of more preferably preventing the inclination of a root bowl with respect to the vertical direction in the case of acting, and a fixing tool for a root bowl used in the method of supporting and supporting the tree. .

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 problems, the present invention brings a root canal contact body into contact with a root beak of a tree, and presses the root pot with the root beard contact to fix the root beard. In a supporting construction method of a tree to be supported and constructed, a root holder 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 trees, characterized in that the contact body for root pot is fixed to the root pot by biting in and the contact body fixing member for root pot is used.

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。   Further, the present invention is a fixing tool for a root pot provided with a contact for a root pot, which is used to fix a root pot of a tree and support the tree, and which contacts the root pot to press the root pot. A root which bites into the root bowl with the root bowl contact body in contact with the root bowl and holds the root bowl contact body from the outside and fixes the root bowl contact body to the root bowl. The present invention also provides a root pot fixing device characterized in that a pot contact body fixing member is further provided.

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, with the contact body for root pot in contact with the root pot, the contact body for root pot is fixed for holding the contact body for root pot from the outside and fixing to the root pot. Since the member bites into the root bowl, it is prevented as much as possible that the root basin contact body deviates from the position where it contacts the root bowl, even when ground subsidence occurs or the tree is subjected to tilting force. As a result, the decrease in the pressing force of the contact body for the root pot against the root pot can be prevented as much as possible. Further, since the biting force by biting the root body contact body fixing member into the root bowl also acts on the root bowl, the biting force of such root body contact body fixing member to the root bowl, and the root body contact body Both of the pressing force of the contact member for the root bowl, which is held and fixed from the outside by the fixing member and the positional displacement with respect to the root bowl is prevented as much as possible, act on the root bowl, thereby supporting the above-mentioned conventional tree support construction technology It is possible to fix the root basin more securely than in the case, and to prevent the inclination of the root basin in the vertical direction more reliably in the case of ground subsidence or in the case where tilting force acts on a 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 root basin contacts may be provided, and a support belt may further be provided which is wound around one root basin contact and another root basin contact. When such a support belt is provided, a plurality of root contact bodies are disposed around the root pot, and the support belt is disposed between one root contact and the other root contact. And the contact body for the root pot is pressed against the root pot by tightening the support belt, and the contact body for the root pot in a state pressed against the root pot by the support belt is the contact body for the root pot It will be fixed to a root bowl with a 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 contact body for the root pot and a tightening force is generated on the support belt by tightening the support belt, the pressing force of the contact body for the root pot acts on the root pot. It becomes. And in the state which pressed the root bowl by the contact body for said root pots by clamping a support belt as mentioned above, the contact body fixing member for root pots bites into the root pot while holding the contact body for root basins from the outside As a result, positional deviation of the contact body for the root pot with respect to the root pot can 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 contact for the root pot is fixed from the outside of the contact for the root pot in a state in which the contact for the root pot is fixed by the tightening of the support belt and the displacement of the contact for the root pot is more reliably prevented. By holding the body and biting the contact holder fixing member for the root bowl into the root bowl, it is possible to more preferably prevent a decrease in the pressing force of the contact body for the root basin against the root bowl, and the effect of fixing the root bowl is more effective. It will improve.

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 the present invention, a root pot mounting body for mounting a root pot may further be provided. When the root pot is placed on such a base holder, it is desirable that the connecting member be connected to the root holder contact and the root holder. By connecting such a connecting member to the contact member for the root pot and the mounting member for the root pot, it is suitably prevented that the contact member for the root pot is displaced relative to the root pot. Become. Also, in this case, when the support belt is disposed around the trunk of the tree and wound around the root contact, the upper side of the root contact is fixed by the tightening force of the support belt, The lower side of the root basin contact body is fixed by the connecting member connected to the root bowl mounting body, and the root basin is fixed by the support belt and the connecting member at the upper and lower sides of the root basin contact body. Therefore, the positional displacement of the root canal contact body can be prevented more reliably, and a reduction in the pressing force of the root canal contact body against the root can be prevented more preferably.

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, it is possible to more securely fix the root basin, and to prevent the inclination of the root basin with respect to the vertical direction more preferably in the case of ground subsidence or in the case where tilting force acts on the tree. It becomes possible to provide the fixing tool for root pots used for the support construction method of these, and its support construction method.

The upper holes 4a are larger than the other holes 4b. A rod-shaped hooking member 5 for hooking a support belt described later is provided at a substantially central position of the top hole 4a. The hooking body 5 is provided by being inserted into a curved portion 6 formed by curving a part of the steel material constituting the contact center piece 2 as shown in FIG.

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。   In addition, the contact body head piece 3 is a contact body central piece so that the head piece upper portion 3 a of the contact body head piece 3 is positioned on the back side of the hole 4 a on the upper side above the hooking body 5. It is fixed to the back side of the upper part 2a of 2. Then, the contact center piece 2 and contact head piece 3 on the upper side of the locking body 5 are slightly bent relative to the contact center piece 2 and contact head piece 3 on the lower side than the locking body 5. It is formed. Further, a hole 7 for inserting a bolt, which will be described later, is formed substantially at the center of the upper portion 3a of the head portion 3 of the contact body.

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 contact member for a root bowl 1 configured as described above, since the contact center piece 2 and the contact head piece 3 below the hooking member 5 are formed straight, they are disposed in the vertical direction. The contact center piece 2 and contact head piece 3 on the upper side of the hook 5 are in contact with the side of the root bowl, and are formed by slightly bending the lower part of the hook 5. So it can touch the shoulders of the root bowl.

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。   Although the contact body for a root pot 1 shown in FIGS. 1 and 2 mainly contacts the side surface of the root pot, it may also contact the shoulder portion of the root pot. Not only the contact body 1 but also a contact body 1 for root can be used which contacts only the side surface of the root pot.

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。   In addition, it is also possible to use a contact member 1 for a root pot generally referred to as a shoulder pad as shown in FIG. The contact member 1 for root pot has a plurality of holes 4 and is formed in a substantially ladder shape, and is used by being in contact with the shoulder 8b of the root pot 8 while being bent as shown in FIG. 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。   In order to be suitably held from the outside by a contact holder fixing member for a root pot described later, the root holder contact member is formed in a substantially ladder shape having a plurality of holes as shown in FIGS. 1 to 4. It is desirable to have a shape like that. However, the shape of the rootpiece contact body is not limited to this, and may be formed in a plate shape without holes. The point is that the shape is not questioned as long as it can be held from the outside by the root holder contact body fixing member described later, and various shapes of root holder contacts 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 contactors for root canal disposed on the outer peripheral surface of the root can be changed according to the size of the root can, for example, four or three. The number of root basin contacts may be one, but in order to cause the root basin contact to generate pressing force on the root basin by encircling the support belt described later and tightening the support belt It is desirable to use a root contact for Moreover, although the thing made of metal, for example is used as a contact member for root pots, the material is not limited, either.

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 contact member fixing member for the root pot may be anything that fixes the root pot by driving it into the root pot while holding it from the outside of the contact pot for the root pot, and the shape is not limited. For example, as shown in FIGS. 5 and 6, it is possible to use the contact pot fixing member 9 for a root pot formed in a substantially rectangular shape on the front side and a substantially U-shaped side surface. A hole 10 for inserting a bolt is bored in the approximate center of the rootpiece contact member 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 application example of the contact member fixing member 9 for a root pot shown in FIGS. 5 and 6 will be described as applied to the contact member 1 for a root pot shown in FIGS. 1 and 2 as shown in FIGS. 7 and 8. The root holder contact member fixing member 9 is driven into the side surface 8 a of the root holder 8 while holding the root holder contact member 1 by the root holder contact member fixing member 9. More specifically, the central piece 9a of the contact member fixing member 9 for the root pot contacts the front of the lower portion 3c of the head portion 3 of the contact portion 3 of the contact member 1 for the root pot, and the contact member for the root pot The root holder contact member fixing member 9 is driven into the side surface 8 a of the root pot 8 so that both side pieces 9 b and 9 b of the fixing member 9 straddle both sides of the head lower portion 3 c of the contact head portion 3. Become. As described above, when the root holder contact body fixing member 9 is driven into the side surface 8 a of the root bowl 8, the root pot contact member 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。   Furthermore, the bolt 11 is inserted into the hole 10 of the contact member fixing member 9 for the root pot, whereby the mutual contact between the contact member fixing member 9 for the root pot and the contact member 1 for the root pot is fixed. In this case, the lower part 3c of the head portion 3 of the contact head 3 also needs to be bored in advance. Such a hole in the lower part of the head piece 3c can be drilled by, for example, a drill at a construction site.

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, similar to the contact member fixing member 9 for a root bowl of FIGS. 5 and 6, the front surface is formed in a substantially rectangular shape and the side surface in a substantially U shape, but as shown in FIG. It is also possible to use the root holder contact body fixing member 9 in which the tip portions 9c, 9c of the formed both side pieces 9b, 9b are formed in a substantially bowl shape. More specifically, in the embodiment of FIG. 9, the tip portions 9c on both sides of the rootpiece contact member fixing member 9 are formed in a substantially triangular shape on the side surface, and the apex angle portion 9e on the front side of the foremost portion 9d is The tip end 9c is formed so as to project outward from the outer surface of the side piece 9b of the contact member fixing member 9 for the root pot, and to taper inward from the apex portion 9e to the foremost end 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 and 9c of the side pieces 9b and 9b of the contact member fixing member 9 for the root pot are formed in a substantially bowl shape, the contact member fixing member 9 for the root pot is It can be easily driven into the side. Further, the apex portion 9e on the front side of the foremost end 9d of the root holder contact member fixing member 9 formed in a substantially triangular shape on the side surface is formed projecting outward from the outer surface of the side piece 9b. Once the pot contact body fixing member 9 is once driven into the side surface 8 a of the root bowl 8, the apex portion 9 e protruding outward from the outer surface of the side piece 9 b acts as a resistance to contact the root pot contact body. It is suitably prevented that the fixing member 9 comes out of the side surface 8a of the root bowl 8 carelessly.

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。   Moreover, as the contact member fixing member 9 for the root pot, as shown in FIG. 10, a nail in which three triangles are continuous in the length direction as the tip 9c of the side piece 9b of the contact member fixing member 9 for root pot. It is also possible to use those formed into a shape. In the embodiment of FIG. 10, the apexes 9e on both sides of three triangles are formed to project outward from the outer surface of the side piece 9b of the contact member fixing member 9 for the root pot, and the apex angles thereof are It is formed to be tapered inward from the portion 9 e toward the tip end side. Then, the tip end portion 9c is formed in a pointed and substantially wedge shape.

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 contact member fixing member 9 for the root pot are formed in a substantially bowl shape, the contact member fixing member 9 for the root pot is easily driven into the side surface of the root pot. be able to. Further, since the apex portions 9e on both sides of each of the three triangles are formed to project outward from the outer surface of the side piece 9b of the contact member fixing member 9 for the root pot, the contact member fixing member 9 for root pot is temporarily After being driven into the side surface 8a of the root bowl 8, a portion 9e of the apex angle protruding outward from the outer surface of the side piece 9b acts as a resistance force, and the root body contact member fixing member 9 is from the side surface of the root bowl. Careless escape is preferably prevented. In particular, in the embodiment of FIG. 10, since the three triangles are formed in the shape of a nail continuous in the longitudinal direction, the portion 9e of the apex angle projecting outward from the outer surface of the side piece 9b is As shown in FIG. 10, a total of 12 pieces are formed, and therefore, the prevention effect of the detachment prevention after the root body contact body fixing member 9 is once driven into the side surface 8 a of the root bowl 8 is better. 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。   Furthermore, as the contact member fixing member 9 for the root pot, as shown in FIG. 11, two plate-like members 12 12 are pivotally supported by pins 13 so as to be rotatable, respectively. It can also be used. The tip portions 12 a of the two plate members 12 are formed in a pointed shape. The root holder contact member fixing member 9 of the embodiment of FIG. 11 is, for example, a root pot as shown in FIGS. 3 and 4 described above and which is in contact with the shoulder 8b of the root pot 8 called a shoulder pad. It can apply to the contact body 1. Specifically, the root holder contact body fixing member 9 is inserted into the hole 4 of the root holder contact body 1 so that the root holder contact body fixing member 9 is driven into the shoulder 8 b of the root holder 8. Be

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 contact holder fixing member 9 for the root bowl is driven into the shoulder 8b of the root bowl 8, as shown in FIG. 12, a portion opposite to the pointed end 12a is pointed. By driving with a hammer or the like in the direction of the arrow in the figure, the two plate-like members 12, 12 rotate slightly outward around the pin 13, respectively, and the two plate-like members 12, 12 respectively In the open state, the root holder contact member fixing member 9 is driven into the shoulder 8 b of the root holder 8. In this manner, the two plate members 12, 12 are respectively opened, and the contact holder fixing member 9 for the root bowl is driven into the shoulder 8b of the root bowl 8. Therefore, the plate member 12 is opened. , 12 acts as a resisting force, and inadvertent removal of the root body contact member fixing member 9 from the shoulder 8 b of the root bowl 8 is suitably prevented.

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 contact member fixing member 9 for the root pot, two side pieces 9 b formed such that the rod-like body has a substantially U-shaped side are connected by one rod-like body 9 f It is also possible to use those formed as such. In the embodiment of FIG. 13, as in the embodiment of FIGS. 5 to 12, the root holder contact member fixing member 9 is not formed of a plate-like member but formed of a rod-like member. Therefore, there is an advantage that the material for forming the root holder 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 shown in FIG. 14, as the contact member fixing member 9 for a root pot, the contact member fixing member 9 for a root pot formed in a bolt shape can also be used. In this case, a nut-like member 14 which can be screwed to the bolt-like contact member fixing member 9 for a root pot is attached to the contact member 1 for a root pot, and as shown in FIG. By screwing the root holder contact member fixing member 9 to the nut-like member 14, the base holder contact member fixing member 9 and the root holder contact member 1 are fixed to each other. In the embodiment of FIG. 14, the contact holder fixing member 9 for the root pot is not driven into the base bowl 8 with a hammer or the like, but the bolt-shaped contact holder fixing member 9 for the root pot is screwed to the nut-like member 14. As a result, the contact holder fixing member 9 for the root pot bites into the root pot 8. Further, in the embodiment of FIG. 14, since a versatile bolt-like member can be used as the contact member fixing member 9 for the root pot, the cost for preparing the contact member fixing member for the root pot is reduced. It has the advantage of being able to

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。   The root pot fixing device according to the present embodiment is arranged around the trunk of a tree in addition to the plurality of root bowl contact bodies 1 and the plurality of root bowl contact body fixing members 9 as described above, A support belt may be further provided to be wound around the plurality of root basin contacts 1. The supporting belt may be directly wound around the root contact body or may be indirectly wound via another member. In any case, when a tightening force is generated on the support belt by the support belt being tightened, the pressing force of the contact body for the root bowl acts on the root bowl. In the case of using such a support belt, it is possible to bridge one support belt around a plurality of contact members for a root bowl 1, but the present invention is not limited thereto. For example, a support ring is wound around the root of a tree. It is also possible to support and support one support belt over the support ring and the contact body 1 for the root pot.

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。   In addition, the root bowl fixing tool of the present embodiment may further include a root bowl mounting body 15 for placing the root bowl. For example, as shown in FIGS. 16 and 17, the root holder 15 is configured to be movable relative to the fixing member 16, which is a direct mounting portion of the root pot, and the fixing member 16. It is possible to use one configured with the moving member 17.

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 FIG. 16, FIG. 17 and FIG. 18, the fixing member 16 is formed by intersecting two frame ridges 18, 18 formed in an elongated square tube shape having a rectangular cross section in a plane substantially cross shape. You can use something like Moreover, it is also possible to use what was comprised so that three frame ridges 18 or four frame ridges 18 may cross | intersect in the center not only in the thing of such a plane substantially cross shape. Furthermore, in addition to those in which the two frame ridges 17 of the fixing member 16 are crossed to form the root pot mounting body 1, the root pot mounting body 1 is, for example, a plane with four frame ridges. It may be formed in a substantially rectangular shape, or may be formed in a substantially triangular planar shape with three frame ridges.

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。   Further, as the moving member 17, for example, as shown in FIGS. 16, 17 and 18, it is externally fitted slidably to the frame rod 18 of the fixing member 16 and, like the frame rod 18, it has an elongated square A slide rod 19 formed in a tubular shape and a driving member 20 attached to the tip end side of the slide rod 19 can be used. The driving member 20, as shown in FIGS. 16 and 17, comprises two right angle portions 20a, 20a, two obtuse angle portions 20b, 20b, and one acute angle portion 20c, one acute angle portion 20c of which is shown. The distal end side is configured to be able to be driven into the side wall surface of the planting hole in which the root bowl 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。   Furthermore, the driving member 20 is formed in a plate shape, and when placed on the bottom surface of the planting hole, the driving member 20 also has a function of causing resistance to the soil at the bottom surface of the planting hole. is there. Further, in the portion where the slide rod 19 and the driving member 20 are continuously provided, as shown in FIG. 19, a driving body 21 for driving with a hammer is protruded upward.

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。   Moreover, when the root pot 8 is placed on the base 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 such as shown in FIGS. 20 and 21 can be used. The adjuster 22 can bring the contact holder 1 for the root pot into contact with the root pot according to the size of the root pot by adjusting the position of the contact member 1 for the root pot with respect to the base holder 15 for the root pot. It is intended to The adjuster 22 is, as shown in FIGS. 20 and 21, a cylindrical adjuster shaft 23 of such a size that can be fitted onto the frame 18 of the fixing member 16, and the adjuster shaft 23. It is comprised with the adjuster frame 24 fixed.

In this case, the winches 48 and 44 are coaxially attached to the root contact 1 by bolts 49 so as to form an angle of about 90 degrees with each other, as shown in FIG. Then, the end 48 a of the winch 48 presses the contact member 1 for the root bowl. Then, in a state where the bolt 49 is inserted into the hole 7 and the mounting bracket 44 and the winch 48 are attached to the contact member 1 for a root bowl, the mounting bracket 44 is configured to be movable left and right. By this, the tightening force of the winch 48 suitably acts not only on the end of the support belt 42 attached to the winch 48 but also to the end of the support belt 42 attached to the attachment bracket 44. 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 the material of the support belt 42, a material that decomposes with the passage of years, for example, biodegradable resin, other materials such as hemp, cotton, jute and the like can be used. As the biodegradable resin, those made of materials such as polylactic acid and polybutylene succinate can be used. Moreover, as a form of the raw material of the support belt 42, it is a thread | yarn which consists of said biodegradable resin, Comprising: For example, the thing of the form which knitted or weaved the thread | yarn used for a tag etc. can be used. In this case, the entire support belt 42 may be made of the above-described degradable material, but in the present embodiment, as shown in FIG. Only the front end portion 45 which is to be a component is made of a decomposable material, and other parts of the belt body 43 may be made of a material that is hard to be decomposed like a general synthetic resin material. With this configuration, for example, the tip 45 of the support belt 42 is made of relatively expensive biodegradable resin, and the portion other than the tip 45 is made of relatively inexpensive versatile synthetic resin. It is possible to reduce the cost.

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 supporting and constructing method for supporting and constructing a tree using the root holder fixing tool configured as described above 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. And the fixing tool for root pots is assembled by each above components.

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, by inserting the slide rod 19 into the frame rod 18, the moving member 17 is integrated with the fixing member 16 to form the base holder mounting body 15, and as shown in FIG. 35, the adjuster shaft portion By externally fitting the slide rod 19 of the moving member 17, the adjuster 22 is connected to the base holder 15. In this manner, four adjusters 22 are attached to the moving member 17 as shown in FIGS. 36 and 37 and 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 holder 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 mounting body 21 with a hammer. In this case, in the present 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 basepiece mounting body 15, and the impacting body 21 is Since it is provided on the tip end side of the slide rod 19, the presence of the adjuster 22 on which the contact member 1 for the root pot is erected becomes a hindrance when performing an operation of placing the driven body 21 with a hammer. This makes it difficult to carry out the 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 such that the adjuster frame 24 in which a pair of steel members are disposed in parallel is fixed to the substantially cylindrical adjuster shaft portion 23, and the adjuster shaft is 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 oriented horizontally with respect to the slide rod 19 with the adjuster shaft 23 as the center. It becomes possible to turn. As a result, when performing the work of placing the placing body 21 with a hammer, the placing operation of the placing body 21 can be easily performed without any trouble of the adjuster 22. By this, as shown in FIG. 39, the driving member 20 can be easily driven into the side wall surface 54 of the planting hole 53.

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 the driving member 20 is driven 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, as shown in FIG. 40, the base body contact body 1 is attached to the adjuster 22. More specifically, the locking piece 25 attached to the upper portion of the adjuster frame 24 is straddled over the two holes 4b and 4b in the contact center piece 2, and the back surface of the rootpiece contact body 1 is obtained. 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, the position of the hole 4b at which the locking piece 25 of the adjuster 22 is locked so as to straddle the hole 4b can be arbitrarily changed, and depending on the position of the hole 4b for locking the locking piece 25, The height of the contact body 1 will change. Therefore, the height of the contact body 1 for root can be adjusted according to the height of the supporting root.

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。   Furthermore, by inserting the bolt 26 into the locking piece 25, the locking piece 25 strung across the holes 4 b and 4 b is inhibited from being separated from the contact center piece 2. As a result, as shown in FIG. 40, the rootholder contact body 1 is connected to the adjuster 22. Then, as shown in FIG. 41, all of the four rootholder contacts 1 are 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, as described above, after the contact member 1 for the root pot is attached to the adjuster 22, the root pot 8 is placed on the mounting member 15 for the root pot. In this case, as shown in FIG. 42, the rooter contact 1 is tilted in advance together with the adjuster 22. That is, since the adjuster frame 24 can be rotated about the adjuster shaft portion 23 of the adjuster 22 as described above, the contact member for a root can 1 can be tilted together with the adjuster 22. As described above, by causing the adjuster frame 24 of the adjuster 22 to rotate sideways with respect to the slide rod 19 and tilting it, the operation of mounting the root pot 8 on the mounting base 15 for the root holder is not disturbed. 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。   Further, in this case, when the root pot 8 is placed on the base holder 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 portion 30 of the projecting piece 29 of the root pot fixing portion 27 pierces the bottom 8 c of the root pot 8 and the root pot fixing portion 27 bites into the bottom 8 c of the root pot 8. , Thereby fixing the base 8. As described above, when the root bowl fixing portion 27 bites into the bottom portion 8c of the root bowl 8 and the root bowl 8 is fixed, the ground sink is generated or the tilting force acts on the tree in the vertical direction. It becomes a factor by which inclination of the root 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 pivoted in the reverse direction to raise the adjuster 22 and the contact member 1 for the foundation again. In this case, as shown in FIG. 44, the position of the adjuster 22 is set to be separated from the base 8.

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 contact body 1 for root pot is brought into contact with the side surface 8a of the root pot 8. In this case, since the adjuster shaft 23 is formed in a substantially cylindrical shape and is externally fitted to the slide rod 19, it is possible to easily move the slide rod 19. Further, since the adjuster shaft 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 the resistance when sliding the adjuster shaft 23 with respect to the slide rod 19 is small. This also makes it easy to move the adjuster shaft 23 at this point. FIG. 45 shows the entire state in which all four contact members 2 for root pot 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 FIG. 46 and FIG. 47, the support belt 42 is wound around the hooking members 5 of the four contact members for a root canal 1. In this case, the support belt 42 is tightened by the winch 48 described above. By this, the upper surface side of the root bowl 8 is supported by the support belt 42, and further, the contact body 1 for root bowl is pressed toward the root bowl 8 by the tightening force of the support belt 42, and the contact body 1 for root basin is more reliable. Will be fixed.

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, while holding the contact member 1 for root pot by the contact member fixing member 9 for root pot, the contact member fixing member 9 for root pot is driven into the side surface 8 a of the root pot 8 . More specifically, the central piece 9a of the contact member fixing member 9 for the root pot contacts the front of the lower portion 3c of the head portion 3 of the contact portion 3 of the contact member 1 for the root pot, and the contact member for the root pot The root holder contact member fixing member 9 is driven into the side surface 8 a of the root pot 8 so that both side pieces 9 b and 9 b of the fixing member 9 straddle both sides of the head lower portion 3 c of the contact head portion 3. Become. Furthermore, the bolt 11 is inserted into the hole 10 of the contact member fixing member 9 for the root pot, whereby the mutual contact between the contact member fixing member 9 for the root pot and the contact member 1 for the root pot is fixed.

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。 Such a root holder contact member fixing member 9 is driven to hold four root holder contacts 1 as shown in FIG.
By thus driving the rootholder contact body fixing member 9 into the side surface 8a of the root bowl 8, the rootholder contact body 1 is held and fixed to the root bowl 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。   In this manner, the root pot contact body fixing member 9 is driven into the side face 8 a 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. Since positional displacement of the root canal contact body 1 with respect to 8 is prevented, and a biting force due to the root pot contact body fixing member 9 being driven into the root bowl 8 also acts on the root bowl, It becomes possible to prevent the inclination of the root bowl with respect to the vertical direction more reliably than in the conventional case when the ground subsidence occurs or the tilting force acts on the tree.

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, after the root holder contact body fixing member 9 is driven into the side surface 8 a of the root holder 8 while holding the root holder contact body 1 from the outside, the soil is filled in the planting hole 53 to close the planting hole Do. This completes the support construction of trees.

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 contact holder fixing member 9 for the root pot and the action of driving the bottom pot fixing member 27 into the bottom 8 c of the root pot 8. The effect of preventing the inclination of the root relative to the vertical direction is further improved in the case where the sinking occurs or the tilting force acts on the tree.
