Abstract

PROBLEM TO BE SOLVED: To solve a problem of requiring a fair investment since a fence becomes a large-scale facility for stretching a wire net having the height of about 2 m over piles by driving the thick wooden erect piles at an interval of 5 to 7.5 m in the conventional snow damage resistant deer preventive fence. SOLUTION: The whole investment amount is sharply reduced by changing a material of the erect piles to steel from conventional wood, and largely expanding an installing interval of the erect piles more than a conventional case by using support members. A column interval is not substantially expanded, and since settlement of the erect piles is not caused by a settlement preventive means of the erect piles and the support members, looseness of the wire net can be prevented, and an effect of the fence can be sufficiently exhibited.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low-cost snow-resistant deer fence for preventing wild animals such as deer from entering farmland and damaging crops.

[0002]

2. Description of the Related Art A conventional beast damage prevention fence has the following configuration. The fences installed to prevent deer damage were driven by thick wooden standing piles at intervals of 5 to 7.5 m and a wire mesh of about 2 m in height.

[0003]

The above-mentioned prior art has the following problems. 1. These fences became extensive facilities and required considerable investment. 2. In order to reduce investment, it is conceivable to use steel standing piles instead of wooden ones.However, when steel standing piles are used, the pile piles sink due to the snow load, which causes the wire mesh to loosen. However, even after the snow had melted, the habit of loosening was not restored, and the effect was not sufficiently obtained in the snowy area.

[0004] The present invention has been made in view of such problems of the prior art, and has as its object to provide the following. 1. The present invention changes the material of the standing pile from the conventional wooden to steel and uses the supporting material (one per 2.5 to 3.75 m) to reduce the installation interval of the standing pile to the conventional 5 to 7.5 m. From 7.5
By greatly expanding to ~ 12m, the total investment amount is significantly reduced, and the use of the support material does not substantially widen the column spacing, and the means for preventing the settlement of the standing pile and the supporting material does not cause the settlement of the standing pile. Therefore, the wire mesh can be prevented from being loosened, and the effect of the fence can be sufficiently exhibited. 2. The present invention seeks to significantly reduce the installation cost in a snowy area, while at the same time preventing the wire mesh from becoming loose due to the snow load.

C. The stay column 2C includes a support bracket 2C1 attached to an intermediate portion in the vertical direction of the corner pillar, an oblique stay column 2C3 connected to the support bracket by a horizontal upper bolt 2C2, and an upper end at the lower end of the stay column. It is composed of a vertical anchor 2C5 connected by a lower bolt 2C4 parallel to the bolt, and an anti-sinking device 2C6 attached to the vertical anchor. In this case, the anti-sinking device 2C6 is a U-shaped bolt 2C

C63. In the anti-sinking frame 2C63, the horizontal piece and the vertical piece are connected at a right angle, and a hole corresponding to the width and the diameter of the U-bolt is drilled in the vertical piece to pass the end of the U-bolt, and a vertical anchor is driven. After that, the vertical anchor is held by a U-shaped bolt at a place where the ground surface is located, and a vertical piece is passed through the U-shaped bolt end and fixed with a nut.

B. The standing pile 3 is composed of the left and right corners 2 and 2
Standing piles 3A and 3
A. . And an anti-sinking device 3B attached to each standing pile. a. The standing pile is made of steel, and is configured to use a round pipe, a square pipe, a C-shaped steel, or the like so that the ground height after being driven into the land is about 2 m. b. The interval between the standing piles is about 7.5 to 12 m. c. The anti-sinking device 3B includes a U-bolt 3B1 and a nut 3
B2 and an anti-sinking frame 3B3 in the form of an angle.

After that, the supporting member is held by a U-bolt at a place where the ground surface is located, and a vertical piece is passed through the end of the U-bolt and fixed with a nut. The supporting material has a length such that it reaches the upper end of the wire mesh from the ground surface. The lower end portion is placed on the ground surface, and the wire mesh is fixed at the upper end portion and at two other positions by hook bolts 4A or the like.

[0013]

EXAMPLES Further, as a result of an experiment under the following conditions,
Very good results were obtained. Instead of fixing the wire mesh directly to the standing pile with hook bolts, etc., FIGS.
The round bar 6 is fixed with the hook bolt 4A or the like, and the wire mesh 4 is sandwiched and fixed between the round bar 6 and the standing pile 3A. If the wire mesh is simply fixed with hook bolts and the horizontal lines of all wire meshes are not fixed with hook bolts, if there are up and down undulations and left and right corners in the installation place, the horizontal lines will be originally when the wire mesh is pulled There is a possibility that it will be displaced in the pulling direction from the position where it should be, and will be separated from the standing pile in the pulling direction. When the wire mesh is fixed as shown in FIGS. 15 to 17, the upper end to the lower end of the wire mesh are firmly fixed to the standing pile by the round bar, so that even if the wire mesh is pulled, the position is shifted or the wire mesh is separated from the standing pile. Without increasing the strength of the entire fence.

[0014]

Since the present invention is configured as described above, the following effects can be obtained. 1. The wooden fence needed to be thick enough to have sufficient strength, and consequently there was no need to consider the settlement of the pillars to use thick standing piles. However, as in the present invention, the installation cost is significantly reduced by using a steel standing pile,
Steel standing piles can avoid sinking due to snow loads. 2. When the standing pile sinks, the wire mesh tends to loosen, and once loose, the slack does not return to its original state even after snow melting, and the effect of the preventive fence cannot be obtained. Therefore, steel standing piles are generally not used, but wooden standing piles have been used exclusively. However, according to the present invention, the standing pile is formed with the settlement prevention means including the U-bolt and the angle-shaped settlement prevention frame. Is now available. 3. Further, since the anti-sinking means is stopped by a U-shaped bolt without making a hole in the pillar, it can be stopped at any place of the standing pile.
Depending on the terrain and geology, there are places where it is not possible to drive sufficiently, but even in such a case, it is possible to change the fixed place on the ground surface and use it.

4. In addition, by using the support material, the installation interval of the standing pile can be reduced from the conventional 5-7.5 m to 7.5-12 m.
Could be greatly expanded. 5. The adoption of steel standing piles and the spread of the standing piles with supporting materials can be widened and the installation cost can be greatly reduced, but this does not impair the strength of the fence and can sufficiently withstand the snow load. As a result, a sufficient effect as a fence is obtained. 6. In addition, wooden standing piles are machined because they are thick, but there are some places in the mountains where machines cannot be inserted. However, in the case of a steel standing pile, since it can be driven manually, construction in the mountains is also possible. 7. In addition, it has effects such as being inexpensive to manufacture, easy to assemble because of a small number of parts, and economical.
