Description

【０００１】
【発明の属する技術分野】
本発明は、鹿などの野獣が農地に侵入して農作物に被害を与えるのを防ぐための低コスト耐雪害防鹿柵に関する。
【０００２】
【従来の技術】
従来の野獣被害防止柵は、下記のような構成となっている。
鹿の被害を防ぐ目的で施設されている柵は、太い木製の立杭を５〜７．５ｍ間隔に打ち込み、これに２ｍ程度の高さの金網を張っていた。
【０００３】
【発明が解決しようとする課題】
従来の技術で述べたものにあっては、下記のような問題点を有していた。
１．こうした柵は大掛かりな施設となり、かなりの投資を必要とした。
２．投資を抑えるには、木製にかえて鋼製の立杭利用が考えられるが、鋼製の立杭を利用した場合は、積雪荷重により立杭の沈下が起こり、それにより金網の弛みが発生し、雪が溶けたあとでも弛るんだ状態の癖が元に戻らず、積雪地帯では十分な効果が得られなかった。
【０００４】
本発明は、従来の技術の有するこのような問題点に鑑みなされたものであり、その目的とするところは、下記のようにすることのできるものを提供しようとするものである。
１．本発明は、立杭の材料を従来の木製から鋼製に変えることと、支持材（２．５〜３．７５ｍに１本）の利用により立杭の設置間隔を従来の５〜７．５ｍから７．５〜１２ｍに大幅に広げることにより、全体の投資金額が大幅に削減すると共に、支持材の利用により実質柱間隔が広がらず、立杭や支持材の沈下防止手段により立杭の沈下などが起こらないので、金網の弛みも防止でき柵の効果が十分発揮できる。
２．本発明は積雪地帯において設置費用を大幅に削減しながら、同時に積雪荷重による金網の弛みを起こさせないようにしようとするものである。
【０００５】

【００１０】
Ｂ．立杭部３は、左右のコーナー部２、２間の土地に所定間隔をもって打ち込まれた立杭３Ａ、３Ａ．．と、各立杭に取付けられた沈下防止具３Ｂから構成されている。

【００１１】

【００１３】
【実施例】
さらに、以下のような条件で実験した結果、極めて良好な結果が得られた。
フックボルトなどで金網を立杭に直接固定するのではなく、図１５ないし図１７のようにフックボルト４Ａなどで丸棒６を固定し、この丸棒６と立杭３Ａの間に、金網４を挟み込んで固定する方法もとることができる。
単に金網をフックボルトで固定し、かつ全ての金網の横線をフックボルトで固定していない場合は、設置場所に上下の起伏や左右のコーナーがあると、金網を引っ張った時に、横線が本来あるべき位置より引っ張り方向へずれたり、立杭部から引っ張り方向へ離れてしまったりする可能性がある。
図１５ないし図１７のように固定すると、金網の上端から下端までが丸棒によりしっかり立杭に密着固定されるので、金網が引っ張られても位置がずれたり、立杭から離れてしまうことがなく柵全体の強度が高められる。
【００１４】
【発明の効果】
本発明は、上述の通り構成されているので次に記載する効果を奏する。
１．木柵は十分な強度を持たせるには太さが必要であり、結果的に太い立杭を利用するため柱の沈下を考慮する必要がなかった。
しかし、本発明のように、鋼製の立杭を利用することにより設置費は大幅に安価となるが、鋼製の立杭は積雪荷重による沈下が避けられる。
２．立杭が沈下すると金網が弛みやすくなり、一度弛むと融雪後も弛みは元に戻らず、防止柵の効果が得られないようになる。
そのため一般的に鋼製の立杭は用いられず、もっぱら木製の立杭が用いられてきた。
しかし、本発明では立杭にＵ字ボルトとアングル状の沈下防止枠からなる沈下防止手段を形成しており、鋼製であっても立杭の沈下が起こらず、安価な鋼製の立杭の利用が可能になった。
３．さらに、この沈下防止手段は柱に穴をあけずにＵ字ボルトで、止めるので立杭のどの場所にも止められる。
地形・地質によっては十分な打ち込みができない場所もあるが、その場合でも地表に固定場所を変更して利用することができる。
【００１５】
４．また、支持材を利用することにより立杭の設置間隔を従来の５〜７．５ｍから７．５〜１２ｍに大幅に広げることができた。
５．鋼製の立杭の採用と、支持材による立杭の設置間隔が広がり大幅な設置費の削減が図れるが、それによって柵としての強度が損なわれるわけではなく、積雪荷重にも十分に耐えられ、柵としての十分な効果が得られる。
６．また、木製の立杭は太いために機械打ち込みとなるが、山中では機械が入れないところもある。
しかし、鋼製の立杭の場合は人手での打ち込みが可能なため、山中での施工も可能である。
７．このほか、安価に製造できる、部品点数が少ないので組立が容易である、経済的である、などの効果をも有するものである。

[0013]
【Example】
Further, as a result of an experiment under the following conditions, extremely good results were obtained.
Instead of fixing the wire mesh directly to the standing pile with hook bolts or the like, the round bar 6 is fixed with the hook bolt 4A or the like as shown in FIGS. 15 to 17, and the wire mesh 4 is placed between the round bar 6 and the standing pile 3A. Can be fixed by sandwiching them.
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 at the installation location, the horizontal lines will be originally when pulling the wire mesh There is a possibility that it will be displaced in the pulling direction from the position where it should be, or will be separated from the standing pile in the pulling direction.
When fixed as shown in FIG. 15 to FIG. 17, since the upper end to the lower end of the wire mesh is firmly fixed to the pile by the round bar, even if the wire mesh is pulled, the position is shifted or the wire is separated from the pile. And the strength of the entire fence is increased.
[0014]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
1. Wooden fences needed to be thick enough to have sufficient strength, and consequently there was no need to consider the settlement of pillars because of the use of thick standing piles.
However, as in the present invention, the installation cost is significantly reduced by using the steel standing pile, but the steel standing pile is prevented from sinking due to the snow load.
2. When the standing pile sinks, the wire mesh becomes easy to loosen, and once loosened, the slack does not return to its original state even after snow melting, preventing the effect of the fence.
For this reason, 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 a settlement prevention means comprising a U-bolt and an angle-shaped settlement prevention frame. Is now available.
3. Further, since the anti-sinking means is stopped with a U-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 cases, the fixed place on the ground can be changed and used.

4. In addition, by using the support material, the installation interval of the standing piles could be greatly increased from the conventional 5-7.5 m to 7.5-12 m.
5. The use of steel uprights and the use of supporting materials to increase the spacing between the uprights can greatly reduce the installation cost, but this does not impair the strength of the fence and can withstand the snow load. As a result, a sufficient effect as a fence can be obtained.
6. Also, wooden 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 steel standing piles, since it can be driven manually, construction in the mountains is also possible.
7. In addition, it has the effects of being inexpensive to manufacture, easy to assemble since the number of parts is small, and economical.

The corner part (2) consists of left and right corner pillars (2A) driven into the land where it is desired to prevent deer and other beasts from entering, ground anchor parts (2B) attached to each corner pillar, and stay pillar parts. (2C).
The standing pile portion (3) includes standing piles (3A, 3A...) Which are driven into the land between the left and right corner portions (2, 2) at a predetermined interval, and a settling prevention tool (3B) attached to each standing pile. ).
The wire mesh (4) is formed in a vertical and horizontal lattice shape, and a wire mesh in a vertical and horizontal lattice shape is stretched between the standing piles to a position of about 2 m in height, and hook bolts (4A) are attached to the standing piles (3A, 3A...). Fix with.
The supporting member (5) is composed of supporting members (5A, 5A,...) Arranged at predetermined intervals between the standing piles, and an anti-sinking device (5B) attached to the supporting members. The material has a length such that it reaches the upper end of the wire mesh from the ground surface. The lower end of the material should be placed on the ground surface, and the wire mesh should be fixed at the upper end and at two other locations.

A low-cost snow-resistant deer fence, comprising: a corner portion (2), a standing pile portion (3, 3,...), A wire mesh (4), and a support portion (5).
The corner part (2) consists of left and right corner pillars (2A) driven into the land where it is desired to prevent deer and other beasts from entering, ground anchor parts (2B) attached to each corner pillar, and stay pillar parts. (2C), and the corner pillar (2A) is made of steel using round pipe, square pipe, or C-shaped steel, and is configured to have a ground height of about 2 m after being driven into the land. The part (2B) is composed of a ground anchor (2B1) in the front-rear direction and a ground anchor (2B2) in the left-right direction, and the ground anchor (2B1) in the front-rear direction is loosely fitted to the ground portion of the corner pillar. A locking ring (2B11) and an anchor (2B12) driven obliquely downward into the ground through the locking ring are provided.
