Description

本発明は、樹木固定装置及び樹木固定方法に関するものである。 The present invention relates to a tree fixing device and a tree fixing method.

例えば、ゴルフ場や公園などの施設、建物外構や道路などには、良好な景観保持の為、樹木は欠かせないものであり、これら樹木は、他の場所で育ったものを掘り起こして移植されるのが一般的である。しかし、この移植した樹木が根付くには時間が掛かる為、移植した樹木は当然その場所に根付くまでの間若しくは半永久的に固定する必要がある。 For example, trees are indispensable for maintaining a good landscape in facilities such as golf courses and parks, building exteriors, roads, etc., and these trees are transplanted by digging up those grown in other places. It is common to be done. However, since it takes time for the transplanted tree to take root, it is naturally necessary to fix the transplanted tree until it takes root or semi-permanently.

そこで、従来、移植した樹木を固定するものとして、例えば特許文献１（特開２００４−１２９５８０号）に開示される樹木用支柱が提案されている。 Therefore, conventionally, as a means for fixing a transplanted tree, for example, a support for a tree disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2004-129580) has been proposed.

この樹木用支柱は、植樹された樹木の近傍で土中に打ち込まれる左右一対の金属製杭部材と、土中に打ち込まれる両杭部材の夫々上端部に伸縮調整可能に接続される左右一対の金属製支柱本体と、両支柱本体の上端部同士をつなぐ金属製水平材とを有し、水平材の中央部が縛り紐によって樹木に縛り付けられるように構成されたものであり、各部材が金属製で強度があり腐食しにくい為、樹木を長く堅固に固定することができる。 This tree support is a pair of left and right metal pile members that are driven into the soil near the planted tree, and a pair of left and right metal pile members that are connected to the upper ends of both pile members that are driven into the soil so that they can be expanded and contracted. It has a metal strut body and a metal horizontal member that connects the upper ends of both strut bodies, and the central part of the horizontal member is tied to a tree with a binding string, and each member is made of metal. Because it is made of wood, it is strong and does not easily corrode, so trees can be fixed firmly for a long time.

しかしながら、この樹木用支柱は、前述したように樹木における地表面から突出している部位を支持する構造であり、樹木を堅固に固定することができるものの、それら樹木に支柱が施されている状態が見え、景観が良くない（その場で自然に育った樹木でない感じを与え、体裁が悪い。）。 However, as described above, this tree support has a structure that supports the portion of the tree that protrudes from the ground surface, and although the tree can be firmly fixed, the state in which the support is provided to the tree is It looks and the landscape is not good (it gives the feeling that it is not a tree that grew naturally on the spot, and it looks bad).

そこで、従来においても、例えば特許文献２（特開２００９−２１９４３２号）に開示されるような樹木固定装置（以下、従来例という。）が提案されている。 Therefore, conventionally, for example, a tree fixing device (hereinafter referred to as a conventional example) as disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 2009-219432) has been proposed.

この従来例は、硬質材で網状に構成された平面材に樹木の根鉢部を載置し、この根鉢部と平面材とを紐状体で連結し、土材で埋めて該土材の重みによって樹木を固定するという所謂地下支柱構造であり、樹木を固定するものが地上に露出しないため、樹木を体裁良く固定することができる。 In this conventional example, a root pot portion of a tree is placed on a flat material composed of a hard material in a net shape, the root pot portion and the flat material are connected by a string, and the soil material is filled with earth material. It is a so-called underground strut structure in which the tree is fixed by the weight, and since the thing that fixes the tree is not exposed on the ground, the tree can be fixed in a good appearance.

特開２００４−１２９５８０号公報Japanese Unexamined Patent Publication No. 2004-129580 特開２００９−２１９４３２号公報JP-A-2009-219432

しかしながら、従来例は、実際に試してみると、樹木の固定が不十分であり、よって、地下支柱構造でありながら堅固に固定できる技術の提案が望まれている。 However, in the conventional example, when actually tried, the fixing of the tree is insufficient, and therefore, it is desired to propose a technique capable of firmly fixing the tree even though it has an underground support structure.

本発明は、前述した問題点に鑑みなされたものであり、従来に無い実用的な樹木固定装置及び樹木固定方法を提供する。 The present invention has been made in view of the above-mentioned problems, and provides a practical tree fixing device and a tree fixing method which have not existed in the past.

好適と考える本発明の実施形態を、図面に基づいて本発明の作用を示して簡単に説明する。 Embodiments of the present invention which are considered to be suitable will be briefly described by showing the operation of the present invention based on the drawings.

例えば、植樹領域50に設けられた凹所51に基体１を配し、続いて、基体１の周縁部を面状補強体３で覆い、続いて、基体１上に樹木30の根鉢部31を配して紐状体２で縛り連結し、続いて、凹所51を土材60で埋める。尚、予め基体１に樹木30の根鉢部31を紐状体２で縛り連結した状態で凹所51に配しても良いし、基体１に根鉢部31を紐状体２で縛り連結した後に、基体１の周縁部を面状補強体３で覆うようにしても良い。 For example, the base 1 is arranged in the recess 51 provided in the tree planting region 50, then the peripheral edge of the base 1 is covered with the planar reinforcing body 3, and then the root pot portion 31 of the tree 30 is placed on the base 1. Is arranged and tied with a string-like body 2 to be connected, and then the recess 51 is filled with earth material 60. The root pot portion 31 of the tree 30 may be tied and connected to the substrate 1 in advance with the string-shaped body 2 and arranged in the recess 51, or the root pot portion 31 may be tied and connected to the base 1 with the string-shaped body 2. After that, the peripheral edge portion of the substrate 1 may be covered with the planar reinforcing body 3.

従って、樹木30を固定するものが地上に露出しないため、樹木30を体裁良く固定することができる。 Therefore, since the thing that fixes the tree 30 is not exposed on the ground, the tree 30 can be fixed in a good appearance.

また、本発明は、樹木30の根鉢部31が縛り連結され根鉢部31の平面視投影形状よりも大きい平面視投影形状の基体１には、凹所51を埋める土材60の重量とともに樹木30の重量もかかる為、樹木30が固定されることになり、しかも、基体１の周縁部を覆う面状補強体３を介して基体１の周囲における土材60の重量も該基体51に付与することができる為、樹木30は堅固に固定される。 Further, in the present invention, the root pot portion 31 of the tree 30 is tied and connected to the base 1 having a plan view projection shape larger than the plan view projection shape of the root pot portion 31, together with the weight of the earth material 60 that fills the recess 51. Since the weight of the tree 30 is also applied, the tree 30 is fixed, and the weight of the earthen material 60 around the base 1 is also attached to the base 51 via the planar reinforcing body 3 that covers the peripheral edge of the base 1. Tree 30 is firmly fixed because it can be given.

即ち、本発明のように基体１の上に配される土材60の重量を利用して樹木30を固定する構造（地下支柱構造）の場合、例えば基体１の平面視投影形状が大きければ大きいほど土材60を受ける表面積が大きくなり、樹木30を固定する力が大きくなるが、基体１が大きくなって重量が増える分、搬送したり凹所51への配設作業が厄介になるなど作業性が悪くなり、コストも高くなるなど、基体１を大きくするにも限界がある。 That is, in the case of a structure (underground strut structure) in which the tree 30 is fixed by utilizing the weight of the earth material 60 arranged on the substrate 1 as in the present invention, for example, the larger the plan view projection shape of the substrate 1, the larger the structure. The larger the surface area that receives the earthen material 60, and the greater the force that fixes the tree 30, but the larger the substrate 1 and the heavier the weight, the more difficult it is to transport and dispose of it in the recess 51. There is a limit to the size of the substrate 1, such as poor properties and high cost.

この点、本発明は、基体１の周縁部を面状補強体３で覆うことにより、基体１の平面視投影形状を大きくしたのと同様な状態とし、この状態で土材60を受けるという構成としたから、基体１を必要以上に大きくする必要はなく（作業性及びコスト性を悪化させることはなく）、樹木30を固定するに十分な重量を基体１に対して簡易且つ確実に付与することができ、樹木30は堅固に固定される。 In this respect, the present invention has a configuration in which the peripheral edge portion of the substrate 1 is covered with the planar reinforcing body 3 to bring the substrate 1 into a state similar to that in which the projected shape in a plan view is enlarged, and the earth material 60 is received in this state. Therefore, it is not necessary to make the base 1 larger than necessary (without deteriorating workability and cost), and a sufficient weight for fixing the tree 30 is easily and surely given to the base 1. The tree 30 can be firmly fixed.

本発明の具体的な実施例について図面に基づいて説明する。 Specific examples of the present invention will be described with reference to the drawings.

本実施例は、樹木30の下部に設けられた根鉢部31を植樹領域50に設けられた凹所51に配して固定するための樹木固定装置である。 This embodiment is a tree fixing device for arranging and fixing the root pot portion 31 provided at the lower part of the tree 30 in the recess 51 provided at the tree planting area 50.

尚、本実施例で言う植樹領域50とは、例えばゴルフ場や公園などの樹木30を移植する任意の領域であり、根鉢部31とは、樹木30を掘り出したときの根とこの根の周囲に付着している土とから成る塊状体であり、本実施例では、この根鉢部31に縄掛けをして根巻きが施されている。 The tree planting area 50 referred to in this embodiment is an arbitrary area for transplanting a tree 30 such as a golf course or a park, and the root pot portion 31 is a root when the tree 30 is dug and the root of the root. It is a lumpy body composed of soil adhering to the surroundings, and in this embodiment, the root pot portion 31 is hooked and wrapped with roots.

具体的には、本実施例は、凹所51の底部に配される基体１と、この基体１に対して根鉢部31を縛り連結する紐状体２と、凹所51に配された基体１の周縁部（及び該基体１の周辺部位にして凹所51の所定部位）を覆う面状補強体３とで構成されている。 Specifically, in this embodiment, the substrate 1 is arranged at the bottom of the recess 51, the string-shaped body 2 that binds and connects the root pot portion 31 to the substrate 1, and the recess 51. It is composed of a planar reinforcing body 3 that covers the peripheral edge portion of the substrate 1 (and a predetermined portion of the recess 51 as a peripheral portion of the substrate 1).

基体１は、図１，２に図示したように棒状部材１ａを縦横に連結して成る平面視正方形の方形枠状部１Ａと、この方形枠状部１Ａの内側に架設状態に連結され棒状部材１ａを交叉状（十字）に連結して成る交叉形状部１Ｂ（十字形状部）とで構成されており、根鉢部31の平面視投影形状よりも大きい平面視投影形状を有する格子形状に構成されている。本書面で言う平面視投影形状とは、平面方向から見た際に所定の面積を有する形状のものを意味する。 As shown in FIGS. 1 and 2, the base 1 has a square frame-shaped portion 1A having a square view in a plan view formed by connecting rod-shaped members 1a vertically and horizontally, and a rod-shaped member erected inside the square frame-shaped portion 1A. It is composed of a cross-shaped portion 1B (cross-shaped portion) formed by connecting 1a in a cross shape (cross), and is configured in a lattice shape having a plan-view projection shape larger than the plan-view projection shape of the root pot portion 31. Has been done. The plan view projection shape referred to in this document means a shape having a predetermined area when viewed from the plane direction.

また、本実施例では、棒状部材１ａとして適宜な金属製の管状体（単管パイプ）を採用しており、この棒状部材１ａ同士を連結クランプ１ｂを用いて連結している。 Further, in this embodiment, an appropriate metal tubular body (single pipe) is adopted as the rod-shaped member 1a, and the rod-shaped members 1a are connected to each other by using a connecting clamp 1b.

紐状体２は、図１に図示したように適宜な合成樹脂製の部材で設けられたテープ状体（平テープ）であり、基体１（棒状部材１ａ）に対して根鉢部31を堅固に縛り連結（図示省略のバックルを使用して緊縛）し得るように構成されている。 As shown in FIG. 1, the string-shaped body 2 is a tape-shaped body (flat tape) provided with an appropriate synthetic resin member, and the root pot portion 31 is firmly attached to the substrate 1 (rod-shaped member 1a). It is configured so that it can be tied and connected (tied using a buckle (not shown)).

尚、紐状体２は、適宜な強度と耐久性を有して堅固に縛り連結でき、環境に優しい材料のものであれば適宜採用し得るものである。 The string-shaped body 2 has appropriate strength and durability, can be tightly tied and connected, and can be appropriately adopted as long as it is made of an environment-friendly material.

面状補強体３は、図１，２に図示したように可撓性を有して腐食しにくい平面視長方形状の網状体若しくは布体であり、本実施例では、適宜な合成樹脂製の網部材（三井化学産資株式会社製の高強度プラスチック網：二軸のテンサー（登録商標））を採用している。 As shown in FIGS. 1 and 2, the planar reinforcing body 3 is a rectangular mesh or cloth in a plan view that is flexible and does not easily corrode. In this embodiment, the planar reinforcing body 3 is made of an appropriate synthetic resin. A net member (high-strength plastic net manufactured by Mitsui Chemicals Co., Ltd .: biaxial tensor (registered trademark)) is used.

本実施例では、面状補強体３を４枚用意しており、この各面状補強体３の大きさは、凹所51に配された基体１の周縁部にして四つの角部夫々に配した際、この基体１の周縁部及び該基体１の周辺部位にして凹所51の所定部位を覆う程度の大きさに設定されている。 In this embodiment, four planar reinforcing bodies 3 are prepared, and the size of each planar reinforcing body 3 is set to the peripheral portion of the substrate 1 arranged in the recess 51, and each of the four corner portions has a size. When arranged, the size is set so as to cover a predetermined portion of the recess 51 as a peripheral portion of the substrate 1 and a peripheral portion of the substrate 1.

この面状補強体３は、基体１を全部覆うような大きさ形状のものであっても、基体１の全ての周縁部を覆うような大きさ形状のものでも良いが、種々試したところ、前述した基体１の周縁部にして四つの角部を覆う程度の大きさ形状で樹木30を固定するに十分であることを確認している（作業性及びコスト性からしても面状補強体３は必要最小限のもので良い。）。 The planar reinforcing body 3 may have a size that covers the entire substrate 1 or a shape that covers all the peripheral edges of the substrate 1, but various trials have been conducted. It has been confirmed that the shape of the peripheral edge of the substrate 1 described above is large enough to cover the four corners and is sufficient for fixing the tree 30 (a planar reinforcement from the viewpoint of workability and cost). 3 may be the minimum required.)

以上の構成から成る樹木固定装置を用いた樹木固定方法について説明する。 A tree fixing method using the tree fixing device having the above configuration will be described.

植樹領域50に重機により掘削して成る凹所51（植穴）を設け、この凹所51に基体１を配する（図３（ａ））。尚、この基体１は現場で棒状部材１ａを組んだものでも、予め工場で棒状部材１ａを組んだものを現場に持ち込んでも良い。 A recess 51 (planting hole) formed by excavating with a heavy machine is provided in the tree planting area 50, and the substrate 1 is arranged in the recess 51 (FIG. 3 (a)). The substrate 1 may be a rod-shaped member 1a assembled at the site, or a rod-shaped member 1a assembled in advance at the factory may be brought to the site.

続いて、基体１の周縁部にして四つの角部に面状補強体３を配して、この基体１の周縁部及び該基体１の周辺部位にして凹所51の所定部位を覆う（図３（ｂ））。この際、基体１の内側部位（交叉形状部１Ｂ）に客土して植え床70を作る。尚、面状補強体３は基体１の周縁部（方形枠状部１Ａ）に限らず、交叉形状部１Ｂに配して覆うようにしても良い。 Subsequently, the planar reinforcing bodies 3 are arranged at the four corners of the peripheral portion of the substrate 1 to cover the peripheral portion of the substrate 1 and the peripheral portion of the substrate 1 to cover a predetermined portion of the recess 51 (FIG. 3 (b)). At this time, soil dressing is made on the inner portion (cross-shaped portion 1B) of the substrate 1 to form a planting bed 70. The planar reinforcing body 3 is not limited to the peripheral edge portion (square frame-shaped portion 1A) of the substrate 1, and may be arranged and covered by the cross-shaped portion 1B.

続いて、樹木30を植え床70上に配し、この状態で基体１に対して根鉢部31を紐状体２で縛り連結する（図３（ｃ））。 Subsequently, the tree 30 is arranged on the planting floor 70, and in this state, the root pot portion 31 is tied and connected to the substrate 1 with the string-like body 2 (FIG. 3 (c)).

尚、予め基体１に樹木30の根鉢部31を紐状体２で縛り連結した状態で凹所51に配しても良いし、基体１に根鉢部31を紐状体２で縛り連結した後に、基体１の周縁部を面状補強体３で覆うようにしても良い。 The root pot portion 31 of the tree 30 may be tied and connected to the substrate 1 in advance with the string-shaped body 2 and arranged in the recess 51, or the root pot portion 31 may be tied and connected to the base 1 with the string-shaped body 2. After that, the peripheral edge portion of the substrate 1 may be covered with the planar reinforcing body 3.

続いて、凹所51を土材60（埋戻し土としての掘削土にピートモスやパーライトなどの土壌改良材を混入したもの）で埋める（図３（ｄ））。この土材60で埋める際、適宜水を付与（水締め）して土材60と根鉢部31との空間を無くすようにする。 Subsequently, the recess 51 is filled with soil material 60 (excavated soil as backfill soil mixed with a soil conditioner such as peat moss or pearlite) (FIG. 3 (d)). When filling with this earthen material 60, water is appropriately applied (tightened with water) so that the space between the earthen material 60 and the root pot portion 31 is eliminated.

本実施例は上述のように構成したから、樹木30を固定するものが地上に露出しないため、樹木30を体裁良く固定することができる。 Since this embodiment is configured as described above, the tree 30 is not exposed on the ground, so that the tree 30 can be fixed in a good-looking manner.

また、本実施例は、樹木30の根鉢部31が縛り連結され根鉢部31の平面視投影形状よりも大きい平面視投影形状の基体１には、凹所51を埋める土材60の重量とともに樹木30の重量もかかる為、樹木30が固定されることになり、しかも、基体１の周縁部を覆う面状補強体３を介して基体１の周囲における土材60の重量も該基体51に付与することができる為、樹木30は堅固に固定される（図４参照）。 Further, in this embodiment, the root pot portion 31 of the tree 30 is tied and connected, and the weight of the earth material 60 that fills the recess 51 is provided on the base 1 having a plan view projection shape larger than the plan view projection shape of the root pot portion 31. At the same time, the weight of the tree 30 is also applied, so that the tree 30 is fixed, and the weight of the earthen material 60 around the base 1 via the planar reinforcing body 3 covering the peripheral edge of the base 1 is also the weight of the base 51. The tree 30 is firmly fixed (see FIG. 4).

即ち、本実施例のように基体１の上に配される土材60の重量を利用して樹木30を固定する構造（地下支柱構造）の場合、例えば基体１の平面視投影形状が大きければ大きいほど土材60を受ける表面積が大きくなり、樹木30を固定する力が大きくなるが、基体１が大きくなって重量が増える分、搬送したり凹所51への配設作業が厄介になるなど作業性が悪くなり、コストも高くなるなど、基体１を大きくするにも限界がある。本実施例に係る基体１は、作業性に影響する大きさ（面積と重量）及びコストを考慮して棒状部材１ａを格子状に組んでシンプルな構造としており、基体１を必要最小限の大きさとしている。 That is, in the case of a structure (underground strut structure) in which the tree 30 is fixed by using the weight of the earth material 60 arranged on the base 1 as in this embodiment, for example, if the plan view projection shape of the base 1 is large. The larger the surface area, the larger the surface area that receives the earthen material 60, and the greater the force for fixing the tree 30, but the larger the substrate 1 and the heavier the weight, the more difficult it is to transport and dispose of it in the recess 51. There is a limit to the size of the substrate 1, such as poor workability and high cost. The substrate 1 according to this embodiment has a simple structure in which rod-shaped members 1a are assembled in a grid pattern in consideration of the size (area and weight) and cost that affect workability, and the substrate 1 is the minimum necessary size. I'm trying.

そこで、本実施例は、基体１の周縁部を面状補強体３で覆うことにより、基体１の平面視投影形状（面積）を大きくしたのと同様な状態とし、この状態で土材60を受けるという構成としたから、基体１を必要以上に大きくする必要はなく（作業性及びコスト性を悪化させることはなく）、樹木30を固定するに十分な重量を基体１に対して簡易且つ確実に付与することができる。 Therefore, in this embodiment, the peripheral edge of the substrate 1 is covered with the planar reinforcing body 3 to bring the substrate 1 into a state similar to that in which the projected shape (area) in a plan view is increased. Since it is configured to receive, it is not necessary to make the base 1 larger than necessary (it does not deteriorate workability and cost), and a sufficient weight for fixing the tree 30 is easily and surely attached to the base 1. Can be given to.

また、本実施例の基体１は、基体１は、棒状部材１ａを縦横に連結して成る方形枠状部１Ａと、この方形枠状部１Ａの内側に棒状部材１ａを交叉状に連結して成る交叉形状部１Ｂとで構成され、方形枠状部１Ａの棒状部材１ａと交叉形状部１Ｂの棒状部材１ａとは適宜な手段により連結されているから、必要最小限の大きさと重量により作業性が良く、しかも、簡易構造故にコスト安にして量産性に秀れることになる。 Further, in the substrate 1 of the present embodiment, the substrate 1 has a square frame-shaped portion 1A formed by connecting rod-shaped members 1a vertically and horizontally, and a rod-shaped member 1a connected in a crossed manner inside the square frame-shaped portion 1A. It is composed of a cross-shaped portion 1B, and the rod-shaped member 1a of the square frame-shaped portion 1A and the rod-shaped member 1a of the cross-shaped portion 1B are connected by appropriate means. Moreover, because of its simple structure, the cost is low and mass productivity is excellent.

また、本実施例は、交叉形状部１Ｂは棒状部材１ａを十字状に連結して成る十字形状部であるから、シンプルな構造でありながら前述した作用効果を確実に奏することになる。 Further, in the present embodiment, since the cross-shaped portion 1B is a cross-shaped portion formed by connecting the rod-shaped members 1a in a cross shape, the above-mentioned action and effect can be surely exhibited even though the structure is simple.

また、本実施例は、棒状部材１ａは管状体（単管パイプ）であるから、軽量で作業性に秀れ、しかも、簡易構造故にコスト安にして量産性に秀れることになる。 Further, in this embodiment, since the rod-shaped member 1a is a tubular body (single pipe), it is lightweight and excellent in workability, and because of its simple structure, the cost is low and it is excellent in mass productivity.

また、本実施例は、面状補強体３は可撓性を有する網状体若しくは布体であるから、この点においても簡易構造故にコスト安にして量産性に秀れることになる。 Further, in this embodiment, since the planar reinforcing body 3 is a flexible net-like body or cloth body, the cost is low and the mass productivity is excellent in this respect as well because of the simple structure.

尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。 The present invention is not limited to the present embodiment, and the specific configuration of each constituent requirement can be appropriately designed.
