Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to various kinds of trees used for greening trees such as parks and gardens of various facilities, or trees used for street trees, and other external forces. The present invention relates to a tree support device that protects a tree from falling down.

[Prior art] Conventionally, trees of parks or gardens, street trees, and the like are formed by crossing trees around the trees in order to prevent the trees from falling down, and the trunks of the trees are mounted on the horizontal members in the above-mentioned towers. Was generally tied up and supported.

Recently, several anchors have been driven deep into the soil around the roots of the tree, and the ropes connected to the upper ends of the anchors in each buried state have been extended to the roots of the trees while pushing the midway against the roots. Means are being adopted to secure the root to the trunk and prevent the fall.

[Problem to be Solved by the Invention] Since the former forms a large tower around a tree, it is possible to surely obtain the effect of preventing the fall, but there is a disadvantage that the appearance is unsightly.

The latter are mostly buried underground, but the rope tied to the trunk at the base of the tree is surprisingly unsightly and very poorly workable. Furthermore, it cannot be expected that the effect of preventing the fall is so large.

In the present invention, it is an object of the present invention to solve the above problems, that is, to provide a tree support device whose configuration is not exposed to the outside and can reliably obtain a tree fall prevention effect. Is what you do.

Means for Solving the Problems The gist of the present invention is a container member for inserting tree roots therein and burying the root in a soil, the container having a skeletal frame as a main body and having an open upper portion. A support member for supporting a holding member that holds down the root of the tree from above, wherein the holding member is detachably attachable to an upper peripheral edge of the container member; and a plurality of holding members that extend and contract from the support member. And a holding member having a root holding pad at a lower end thereof.

The above-mentioned trees are not particularly limited, but mainly include trees used for street trees, park greening, and the like.

It is necessary for the container member to be able to connect the soil filled with the tree therein to the surrounding soil,
For this purpose, the skeleton frame is mainly composed. The shape and the like are not particularly limited. A box shape is the easiest to manufacture, but may be a bottomed cylindrical shape that is circular when viewed from a plane.

In addition, since the supporting member supports the holding member that hangs down and presses the root of the tree, the supporting member needs to have sufficient strength, but there is no reason to limit to a specific configuration. For example, it can be composed of a plurality of plate-like arm pieces. Then, one end of each arm piece is detachably attached to the upper peripheral edge of the container member, and the other end thereof is directed to the center in the horizontal direction of the container member, and the respective members are equiangularly spaced. be able to.

Furthermore, if the holding member is also configured to be extendable and contractable and can hold the root of a tree inserted in the container member,
It is not limited to a specific configuration. Thus, for example, the holding member is a nut member fixed to the support member and a bolt member screwed to the nut member, and a disk-shaped pad as the root holding pad is fixed to the lower end. And a bolt member.

[Operation] Since the present invention has the above configuration, it can be used for supporting a tree as follows.

First, a required position where a tree is to be planted is dug down, and the container member is disposed therein.

A root of a tree is charged in the container member in advance, a support member is fixed to a periphery of the container member, and a pressing member is extended on the container member so that a root holding pad is pressed against the root of the tree. Alternatively, after the container member is inserted in the dug-down position, the root of the target tree is inserted, and then the support member is attached to the periphery of the container member, the holding member is extended, and the root is held down by the root holding pad. Press from above.

Thereafter, the soil is buried back in the dug-down position. Other operations are the same as in normal tree planting.

 Thus, the tree planting operation by this device is completed.

Thus, the root of the tree is pressed from above by the root holding pads of the plurality of holding members, and the lower part of the root is supported by the bottom of the container member. Therefore, even if an external force acts on the tree due to the wind pressure or the like, the root is supported to prevent the tree from falling, so that the tree is reliably prevented from falling.

Moreover, since all components are buried underground, there is no harm to the appearance of trees.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, as a container member, a skeletal frame 1, 1,. A square protective box 3 is formed.

On the upper edge of the four corners of the protective box 3, a triangular support plate 5 is fixedly mounted on a plane from which four support arms 4, 4... The support plates 5, 5,...
Two bolt holes 6, 6 are respectively formed.

On the other hand, as shown in FIGS. 1 and 2, the support arm 4 has a nut 7 fixed at the lower end thereof and a bolt 9 having a disk-shaped root holding pad 8 fixed at the lower end. Screw together. The nut 7, the root holding pad 8 and the bolt 9 constitute a holding member. In addition, the support arms 4, 4
At the rear end, two bolt holes 10, 10 corresponding to the bolt holes 6, 6 of the support plates 5, 5,.

Since this embodiment has the above-described configuration, it can be used for supporting the tree 11 as follows.

First, a required position where the tree 11 is to be planted is dug down, and the protective box 3 is inserted and arranged therein. At this time, the third
As shown in the figure, the upper edge of the protective box 3 is made to substantially coincide with the ground line. After that, the roots 12 of the target tree 11 are inserted into the protective box 3, and the supporting arms 4, 4,...
Are aligned with the bolt holes 6, 6, 10, 10 of each other, and are tightened and fixed by bolt nuts (not shown).
Next, the screwing state of the bolt 9 and the nut 7 of the holding member is adjusted to bring the root holding pad 8 into pressure contact with the upper part of the root 12 of the tree 11.

Thereafter, as shown in FIG. 3, the soil is backfilled, and further, as shown in FIG. 4, protective plates 13, 13 for protecting the periphery of the tree 11 between the support arms 4, 4,. Place ...

 Other operations are the same as in the case of normal tree planting.

Thus, the tree planting operation by this device can be completed easily.

[Effects of the Invention] According to the present invention, the root of a tree is pressed from above by the root holding pads of the plurality of holding members, and the lower part of the root is supported by the bottom of the container member. Further, the container member is firmly held by the surrounding soil. Therefore, even if an external force acts on the tree due to the wind pressure or the like, the root is supported to prevent the tree from falling, so that the tree is reliably prevented from falling.

In addition, most of the components are buried in the ground, and the exposed parts also serve to protect the ground surface around the trees, and there is no inconvenience in appearance, so there is no risk of damaging the appearance of the trees .
