【考案の詳細な説明】
[考案の目的]
(産業上の利用分野)
この考案は、街路樹や公園の立木などの樹木を
支持してその傾倒を防止する樹木支持装置に関す
る。[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to a tree support device that supports trees such as street trees and standing trees in parks and prevents them from leaning.
(従来の技術)
樹木を支持してその傾倒を防止する手段とし
て、樹木の幹を八ツ掛支柱や鳥居支柱で支持する
ことが一般に知られている。(Prior Art) As a means of supporting a tree and preventing it from leaning, it is generally known to support the trunk of a tree with a yatsukake post or a torii post.
ところが、このような支柱を用いる手段である
と、外観が悪いばかりでなく、幹の周囲に支持配
置用の比較的広いスペースを確保しなければなら
ないとともに、その支柱が通行の邪魔となり、さ
らに耐久性も低いという難点がある。 However, using such supports not only looks bad, but also requires a relatively large space to be secured around the trunk for support, the supports obstruct traffic, and are not durable. It has the disadvantage of being low in sex.
そこで、第6図に示すように、地面に植付穴a

埋め、前記ワイヤロープgの緊張力で樹木bを支
持することが行なわれるようになつてきている。 Therefore, as shown in Figure 6, we made a planting hole a in the ground.
, insert the root ball c of the tree b into this planting hole a, attach the split support ring d to the root trunk of the tree b, and place the tree e around the upper periphery of the root ball c. , and an anchor f around the bottom of the planting hole a.
Drive the wire rope g between the support ring d and the anchor f, straddling the tree e, and tighten the wire rope g with a ratchet or the like to tighten the root ball c.
is fixed at the bottom of the planting hole a, and then embankment is poured over and around the root ball c to fill it in its entirety, and the tree b is supported by the tension of the wire rope g. It's starting to look like this.

た。この考案はこのような問題点の解決を目的と
したものである。(Problems to be Solved by the Invention) However, with such a conventional support structure, the tension force of the wire rope G is applied to the root trunk of the tree B through the support ring b, which damages the root trunk. The growth of tree b will be adversely affected. Furthermore, if an attempt is made to more firmly fix the root ball c to the bottom of the planting hole a by increasing the tension of the wire rope g, not only will the root trunk be further damaged, but the tension of the wire rope g will be too high. Through the tree e, it is applied locally to the upper periphery of the root ball c, causing the root ball c to collapse, and as a result, there is a limit to the tension force that can be applied to the wire rope g, and as a result, the root ball c cannot be fixed with sufficient strength. The problem was that it was difficult to do so. This invention is aimed at solving these problems.

is a planting hole dug in the ground, and good quality soil 2 is spread at the bottom of this planting hole 1. and planting hole 1
The root ball 4 of the tree 3 is inserted inside, and this root ball 4 is placed on the quality soil 2. Further, an annular holding plate 5 is provided on the upper surface of the root ball 4, and this holding plate 5 has a circular opening 6 in the center, through which the trunk of the tree 3 extends above the planting hole 1. It's out. The inner diameter D of this opening 6 is set to be sufficiently larger than the outer diameter d of the root trunk of the tree 3, for example, d = 2 to 3d, so that the periphery of the opening 6 does not come into contact with the root trunk. It is planned.

7aが形成されている。 The holding plate 5 is composed of, for example, three equal divided pieces 7. An arm 8 is provided on each of these divided pieces 7, spanning between the adjacent divided pieces 7, and bolts 9 are screwed from these arms 8 to the adjacent divided pieces 7, whereby three of the divided pieces 7 are integrally connected via each arm 8. Each arm 8 is bent in a substantially U-shape, and the tip portions at both ends protrude radially from the outer periphery of the holding plate 5, further extending to the outside of the outer periphery of the root ball 4, and wire rods are attached to these extending portions. An eye bolt 10 for insertion is attached. Note that each divided piece 7 of the holding plate 5 has a large number of slit-like through holes 7a formed therein.

1 is entered. And these anchors 11
Wire rods 12 such as wire ropes are hooked to the wire rods 12, and these wire rods 12 are drawn out between both ends of the arm 8 through the eye bolts 10.Furthermore, tightening tools 13 such as ratchets and turnbuckles are attached between the ends of these wire rods 12. By operating the tightening tool 13, a certain tension force is applied to each wire rod 12, and the root ball 4 is pressed downward and fixed to the bottom of the planting hole 1 by the tension force of the wire rods 12. After the root ball 4 is fixed in this way, embankment is poured into the planting hole 1, and this embankment holds the root ball 4 together with the holding plate 5, each arm 8, each wire rod 12, and each tightening tool 13. It is hidden underground.

有効に作用する。 To describe the construction procedure for such a tree support device, first, high quality soil 2 is spread at the bottom of the planting hole 1, the root ball 4 of the tree 3 is placed on top of this high quality soil 2, and the tree 3 is placed on top of the high quality soil 2. It is held in a substantially vertical position using appropriate holding means. Thereafter, the divided pieces 7 of the holding plate 5 are arranged on the upper surface of the root ball 4 so as to surround the root trunk of the tree 3, and further, the arms 8 are arranged evenly on these divided pieces 7. Then, the arm 8 and the divided piece 7 are tightened with bolts 9 to integrally connect the three divided pieces 7. In addition, anchors 1 are placed directly below the extending portion of each arm 8 around the bottom of the planting hole 1.
1 is driven in, wire rods 12 are hooked to these anchors 11, these wire rods 12 are drawn out between both ends of arm 8 through eye bolts 10, and tightening tools 13 are respectively attached between both ends of the drawn wire rods 12. Then, while checking the inclination and position of the tree 3, operate these tightening tools 13 evenly to tighten the wire rod 1.
Tension is gradually applied to 2 to fix the root ball 4 to the bottom of the planting hole 1. After that, filling soil is poured into the planting hole 1, and the root ball 4 as well as the holding plate 5, each arm 8, each wire rod 12, and each tightening tool 13 are buried and covered in the soil, thereby supporting the tree 3. is completed. It is preferable to drive the anchor 11 directly below the extending portion of the arm 8. By doing so, the wire rod 12 is stretched perpendicularly from the anchor 11 to the extending portion of the arm 8. All of the tension acts effectively as a force that presses the root ball 4 downward.

とができる。 With this kind of tree support structure, the supporting members are not exposed on the outer periphery of the trunk unlike when using pillars, so the appearance can be maintained in good condition, and the area around the trunk can be left wide open. You can leave it there. Then, the tension force of the wire rod 12 is not applied to the root trunk of the tree 3 at all, but is applied uniformly to the entire area around the root on the upper surface of the root ball 4 through the holding plate 5, which may damage the root trunk or cause the root ball 4 to The tree 3 does not collapse, so it is possible to increase the tension of the wire rod 12 and firmly press down the root ball 4.
can be supported in a stable and robust state for a long period of time.

ようになつている。 4 and 5 show a second embodiment of this invention, in which the holding plate 5 is composed of four divided pieces 7. A connecting plate 15 is provided spanning between adjacent divided pieces 7, and bolts 16 are screwed from these connecting plates 15 to the adjacent divided pieces 7, so that each divided piece 7 is connected to each connecting plate. They are integrally connected via 15. Eight arms 8 are arranged radially on the upper surface of the presser plate 5.
are provided, and these arms 8 include, for example, a fixing rod 8a formed integrally with the divided piece 7, and this fixing rod 8a.
The movable rod 8b is attached to the fixed rod 8a via a bolt 17.
It is designed so that it can be fixed at any position in the longitudinal direction.
このような構成の場合においては、根鉢4の外
径寸法が種々異なる場合にその外径寸法に応じて
