[0003]

However, in such a fixture, it is necessary to drive a long pile 20 into the ground in order to secure the drag in the ground, but the planting position of the tree is not sufficient. Is a street, and if there are buried objects such as gas pipes, water pipes, and cables in the ground, there is a risk that these buried objects may be damaged when the pile body 20 is driven.

[0004] The present invention has been made in view of the above circumstances, and by shortening a conventional long fixing device, damage to underground buried objects can be avoided, and the fixing device is lowered for that purpose. By increasing the area of the underground resistor in order to secure the drag of trees, trees can be safely and reliably planted in streets where there are buried objects such as gas pipes, water pipes, cables, etc. It is an object of the present invention to provide a self-standing fixture and a fixing method for a planted tree.

[0005]

In order to achieve the above object, a self-standing fixture for planted trees according to the present invention is fixed to an upper surface of an angle member forming a right angle two sides of a pressing side and a fixing side on the pressing side. A through hole for inserting a pin is provided, and a hook is fixedly provided at an upper end of the pressing side. And the pressing side is extended outwardly of the one side surface, and a tool receiver is fixedly provided at the upper end of the resistance plate.

[0006] In addition, according to a self-standing fixing method of a planted tree of the present invention, a through hole is formed in an upper surface of the pressing side of an angle material forming a right side of a pressing side and a fixed side, and an upper end of the pressing side is provided. A fixed side of the angle material is fixed in a bending curve direction to one side of a three-sided bent resistance plate having a U-shaped cross section, and the pressing side is outward of the one side. A plurality of self-supporting fixtures of planted trees formed by fixing a tool receiver to the upper end of the resistance plate at intervals along the outer periphery of a root pot placed in a root hole, By directing each pressing side toward the center of the root mortar and hitting each tool receiver with a tool and hitting it, each resistance plate is driven into the ground and each pressing side is pressed against the upper edge of the root mortar, Next, a fixing pin was inserted into the through hole of each pressing side, and a tightening band was hooked on each hook to tighten. It is.

[0007]

In the above configuration, the fixing tool driven into the ground along the outer periphery of the root mortar 11 is such that the resistance plates 7 are swastika on the outer periphery of the root mortar 11 (however, the fixing device provided on one (Not limited to four) and buried and fixed in the ground,
Each pressing side 2 locks the upper edge of the root pot 11.

Next, a fixing pin 4 is inserted into the through hole 5 of each pressing side 2.

When the tightening band 12 is hung on each hook 6 and tightened, the angle members 1 are bound toward the center of the root pot 11, whereby the fixed side 3 of each angle member 1 is fixed to the outer periphery of the root pot 11. Pressure.

In such a state that the fixture and the mortar 11 are integrated, the outer side surface 7c of each resistance plate 7 resists against earth pressure acting in the center direction of the mortar 11. And
The side bottom surface 7b of the resistance plate 7 resists earth pressure acting in the circumferential direction of the root mortar 11.

According to the present invention described above, the resistance to earth pressure is much greater than that of a conventional long pile, and the resistance plate 7
Even if the depth is shallow, it can sufficiently resist the external force that tries to lay down the tree.

Therefore, according to the present invention, it is possible to make the depth of the resistance plate 7 approximately equal to the depth of the root hole 10.
At the time of excavation at 0, since the presence or absence of a buried object in the surrounding soil has been confirmed, the resistance plate 7 can be driven without contacting the underground buried object.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall perspective view of a fixture according to the present invention. FIG. 2A is a top view of the fixture shown in FIG.
(b) is a front view thereof, and FIG. 2 (c) is a side view thereof. FIG.
(a) is a side view showing the installation state of the fixture according to the present invention, and (b) is a perspective view of the tool. FIG. 4 (a) is a side view showing a state where trees are planted using the fixture according to the present invention, and FIG. 4 (b) is a plan view thereof.

In FIG. 1, an angle member 1 is formed by bending a middle part of a grooved steel material toward a flange side to form two right-angled sides, one side being a pressing side 2 and the other side being a fixed side 3. According to such bending, the flange of the pressing side 2 faces downward and comes into contact with the peripheral edge of the root pot 11 such that the flange bites into the periphery (see FIG. 4A).

Then, a through hole 5 for inserting the fixing pin 4 is formed in the upper surface of the pressing side 2 of the angle member 1,
A hook 6 is fixed to the upper end of the pressing side 2.

As shown in FIG. 2A, the resistance plate 7 is formed by bending a steel plate into three surfaces having a U-shaped cross section, that is, one side surface 7a, one side bottom surface 7b, and the other one side surface 7c. As shown in FIG. 2 (b), one side surface 7a is longer than the other side surface 7c by a length L, and the lower side 7d of the side bottom surface 7b is inclined.

The fixed side 3 of the angle member 1 extends in the direction along the bending curve with respect to one side surface 7a of the resistance plate 7 as described above.
Is fixed, and the pressing side 2 of the angle member 1 protrudes outward from the one side surface 7a. When the fixing side is fixed such that the angle side of the fixed side 3 is fixed to the inner surface of the one side surface 7a, the one side surface 7a is located outside the fixed side 3 below the pressing side 2. The one side surface 7a comes into contact with the root pot 11 side.

Further, a tool receiver 8 is fixed to the upper end of the side bottom surface 7b of the resistance plate 7. This tool receiver 8 has a recess 8a at the center of the upper end.
The width of the lower end of the bar member shown in FIG. 3 (b) is increased to form a concave portion 9a in the center of the lower end.
a is engaged with the concave portion 8a of the tool receiver 8, so that the degree of engagement at the time of hitting is improved.

In the above fixture, the depth of the resistance plate 7 is determined by the excavated root hole 1 when the fixture is buried as follows.
It is formed so as not to exceed a depth of 0.

In order to plant a tree using the above-mentioned fixture, as shown in FIG. 3A, a root pot 11 of a tree to be planted is placed in a root hole 10 excavated in the ground. .

The excavation of the root hole 10 is performed while confirming the presence or absence of a buried object in the ground, and at that time, it is confirmed that there is no buried object in the soil around the root hole 10. Such an investigation around the root hole 10 is easy because it is performed after the root hole 10 is excavated.

Thereafter, as shown in FIGS. 4A and 4B,
A plurality of fixtures are arranged at intervals along the outer periphery of the root mortar 11, each pressing side 2 is directed toward the center of the root mortar 11, the tool 9 is applied to the tool holder 8, and the tool 9 is hammered or the like.
Hit the top of the In this beating, each pressing side 2 has a root bowl 11
Until the upper edge is pressed. Thereby, the flange side of each pressing side 2 bites into the upper edge of the root pot 11 and is locked.

Also, since the lower edge 7d of the resistance plate 7 is inclined by this beating, the resistance plate 7 enters while being deflected to the root mortar 11 side, and the resistance plate 7 extends along the root mortar 11 of the resistance plate 7. The side surface 7a abuts against the side of the root mortar 7 and presses and clamps the outer periphery of the root mortar 11.

Since the resistance plate 7 is fixed in the ground to such an extent that the resistance plate 7 does not exceed the depth of the root hole 10, a buried object exists around the root hole 10, which has been investigated in advance. Since the resistance plate 7 does not enter the position deeper than the root hole 10, the resistance plate 7 does not damage the buried object in the soil.

Next, the fixing pin 4 is inserted into the through hole 5 of each pressing side 2 and inserted into the upper edge of the root mortar 11, thereby integrating each pressing side 2 and the root mortar 11. A fastening band 12 is hung on each hook 6 so that each angle material 1 is
Tighten them so that they bind in the direction of the center of each
Achieve solid integration with 1.

In such a state that the fixing tool and the root mortar 11 are integrated, as shown in the plan view of FIG. 4B, the side bottom surface 7b and the one side surface 7c of the resistance plate 7 are perpendicular to each other. A plurality of wide resistance surfaces can be formed in two directions to resist earth pressure.

The mounting order of the fixing pins 4 and the tightening bands 12 depends on the situation at the site. That is, when the soil around the root hole 10 is soft, the resistance plate 7 is loosely buried in the soil. At this time, the fixing pins 4 are first attached, and then the tightening band 12 is tightened.

When the soil around the root hole 10 is firm, the burial state of the resistance plate 7 in the soil is fixed.
May be attached.

Finally, the excavated soil of the root hole 10 is buried in the root hole 10 to complete the planting operation.

[0031]

As described above, according to the self-standing fixture and method for fixing a planted tree of the present invention, the resistance plate is formed as a wide-area resistor bent on three sides. Even if the board is short, the resistance against earth pressure is much stronger than conventional long piles, and even if the depth of the resistance board is shallow, it can sufficiently resist external forces that try to lay down trees Things.

Further, according to the present invention, since the resistance plate can be shortened in this way, the length of the resistance plate can be configured so as not to exceed the depth of the root hole in the state where the fixing tool is driven. Since it was confirmed that no buried object already existed at the time of excavation of the root hole, the work of driving the fixing tool could be carried out with security and the buried object could be prevented from being damaged. It is particularly effective for tree planting in urban areas where pipes, cables, etc. may be buried.

Further, the outer periphery of the mortar is sandwiched by one side with respect to the resistance plate in the present invention, and the underground fixture is integrally fixed to the mortar by attaching the fixing pin and tightening the tightening band. Therefore, the fixing power of the root pot in the ground is strong, and it is a good support for the independent planting of trees.
