Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support for a tree used for preventing inclination and overturning of transplanted trees.

[0002]

2. Description of the Related Art Generally, when a tree for planting is transplanted, the trunk of the tree is supported by a reinforcing pillar standing on the ground until the roots of the tree grow sufficiently.
The inclination and the fall are prevented.

In such a reinforcing column, since logs and metal pipes assembled in a gate shape are arranged around the trunk, there are drawbacks such as poor appearance and obstruction of traffic.

In view of this, a method of supporting a tree by using a floor-board anchor having no exposed portion above the ground has been proposed in Japanese Laid-Open Patent Publication No. 5-184248 and the like, instead of such a ground-supporting type.

This floor-board anchor is formed by fixing flat plate-like stabilizers projecting radially outward from the outer periphery of the bottom of the root pot of a tree to the corners of a rectangular frame, and the stabilizers have roots. A string-like member that can be tightened around a bowl is fixed.
Then, a root pot of the tree is placed on the floor plate-shaped anchor arranged at the bottom of the planting hole, and the root pot and the floor plate-shaped anchor are integrally fixed by the string-shaped member, which is used for the planting. The trees are supported underground by being buried in the holes.

[0006]

By the way, a root pot of a tree is a root pot of a transplanted tree dug out together with surrounding soil, wrapped with straw, and tied with rope. It will be 1.0 to 1.5 m, and if the weight of the trunk and branches and leaves is added to this, the overall load will be quite large. However, in the conventional floor plate-shaped anchor on which the heavy-load root bowl is placed, as described above, the flat plate-shaped stabilizers are fixed to the respective corners of the rectangular frame body and have a simple structure. Therefore, there is a problem in that the load concentrates on the connecting portion of the frame and each stabilizer, and it is difficult to obtain sufficient strength to withstand the heavy load of the root bowl.

Further, since the trees are supported only by the resistance action of the stabilizers fixed to the corners of the frame to the soil, if the stabilizers are small, sufficient supporting force cannot be obtained and the stabilizers cannot be obtained. If you increase, the water will be cut off by the stabilizer,
There is a problem that support occurs in aeration and root growth.

Further, in the conventional construction, one floorboard-shaped anchor is required for each tree, and the supporting position of the root pot is limited to the central portion of the floorboard-shaped anchor. There is a problem that the trees of the above can not be supported at the same time, or cannot be supported at any position.

An object of the present invention is to provide a support for a tree that can solve the above-mentioned conventional problems.

[0010]

Further, a plurality of grating boards are horizontally connected, and a root belt of a plurality of trees is fixed at an arbitrary position on the plurality of grating boards by a fixing belt connected to an arbitrary main bar of each grating board. By doing so, the root pot group unit may be configured.

[0013]

[Operation] With a grating plate composed of a plurality of main bars arranged in parallel at a predetermined interval and a plurality of cross bars arranged orthogonally to each main bar in a grid pattern, sufficient strength to withstand the load of the root pot Is obtained.

Further, although the upper and lower end surfaces of the individual main bars constituting the grating plate provide a resistance action to the soil, a plurality of main bars can increase the overall resistance area, and Combined with the fact that the stress generated in the main bar is dispersed in each main bar, the root bowl can be sufficiently supported. Also, since there is a gap between each main bar, there is no problem with water flow, ventilation, root growth, etc.

Further, since the fixing belts can be connected to arbitrary positions of the plurality of main bars forming the grating plate, the supporting position of the tree can be freely set, and
By connecting a plurality of grating plates, it is possible to simultaneously support a plurality of trees on artificial ground such as concrete.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A reference embodiment of the present invention will be described with reference to FIGS. In the drawings, reference numeral 1 denotes a grating plate arranged at the bottom of a root pot A of a tree. As shown in FIGS. 3 and 5, the grating plate 1 includes a plurality of main bars 2 arranged in parallel at predetermined intervals, and The main bar 2 and the plurality of cross bars 3 arranged orthogonally to each other are formed in a lattice shape, and the peripheral edges thereof are surrounded by the side bars 4 to form a substantially rectangular shape.
The joint portions of the main bar 2, the cross bar 3 and the side bar 4 are firmly fixed by welding.

U-shaped hooks 5 (outside the present invention) are fixed to the four corners of the grating plate 1, respectively.
The fixed belts 6 are connected to the respective ones by inserting one ends thereof. Each fixed belt 6 is provided with a buckle 7 so that its length can be adjusted, and the other end thereof is a ring-shaped connecting portion 8 into which a tightening ring 9 is inserted.

The tightening ring 9 is made of a flexible belt material, a metal wire or the like, and is arranged above the root pot A so as to surround the trunk B of the tree. The tightening tool 10 having a ratchet mechanism reduces the diameter of the tightening ring 9. It is possible. Then, the tightening ring 9 is reduced in diameter and the fixing belt 6 is stretched vertically around the peripheral portion of the root pot A, whereby the grating plate 1 is fixed to the root pot A.
