Description

本発明は、侵入防止柵用面材及び侵入防止柵に関する。 TECHNICAL FIELD The present invention relates to an intrusion prevention fence face material and an intrusion prevention fence.

近年、野生動物による獣害は、農業のみならず、森林や各種インフラに対しても影響を及ぼしており、被害が深刻化している。これは、鉄道、道路等の交通インフラ、太陽光発電所等の電力インフラ等が、野生動物の生活圏に設置されることが一因とされる。こうした被害を防止するために、支柱間に架設された面材によって野生動物の侵入を防止する侵入防止柵が設置されている。面材としては、例えば樹脂製の網、棒鋼を溶接した溶接金網、鋼線を撚り合わされた亀甲金網等が用いられ、亀甲金網が用いられる侵入抑止柵として、例えば特許文献１～３の開示技術が提案されている。 In recent years, damage caused by wild animals has affected not only agriculture but also forests and various infrastructures, and the damage has become more serious. One of the reasons for this is that transportation infrastructure such as railroads and roads, power infrastructure such as solar power plants, and the like are installed in the habitat of wild animals. In order to prevent such damage, anti-intrusion fences are installed to prevent wild animals from entering with panels installed between the pillars. As the face material, for example, a resin mesh, a welded wire mesh made by welding steel bars, a tortoiseshell wire mesh in which steel wires are twisted, and the like are used. is proposed.

特許文献１には、設置面に立てた状態で配置され、可撓性を有する複数本の線状材をねじり合わせて構成した隔網材と、棒状であり、設置面に立てた状態の前記隔網材を設置面に固定する固定材とを有し、前記固定材は、前記隔網材の一部に接触した状態で設置面に配置され、前記隔網材は、線状材の長さ方向に曲げ撓ませた状態で設置面に配置され、かつ、設置面の形状に沿うよう、該隔網材の端部を設置面に接触させている動物侵入防止柵が開示されている。 In Patent Document 1, there is disclosed a separation mesh member arranged in an upright state on an installation surface and configured by twisting a plurality of flexible linear members, and a bar-shaped mesh member in a state of being erected on the installation surface. and a fixing member for fixing the separation nets to the installation surface, the fixing member is arranged on the installation surface in contact with a part of the separation nets, and the separation nets are lengths of the linear members. An animal entry prevention fence is disclosed which is arranged on an installation surface in a state of being bent in a vertical direction, and in which the ends of the separating net material are brought into contact with the installation surface so as to follow the shape of the installation surface.

特許文献２には、保護地と保護地の外側とを隔てるように間隔をあけて立設された複数の支柱と、支柱間に取り付けられる侵入抑止部材と、を備え、侵入抑止部材は、支柱間に架け渡される複数の線材と、最下段の線材から保護地の外側の地面に沿い延長する網体とを、備え、網体として亀甲金網が用いられる動物侵入抑止柵が開示されている。 Patent document 2 includes a plurality of pillars erected at intervals so as to separate the protected area from the outside of the protected area, and an intrusion deterrent member attached between the pillars, wherein the intrusion deterrent member comprises the pillars. Disclosed is an animal intrusion deterrent fence using a tortoiseshell wire mesh as the net body, which includes a plurality of wire rods that are bridged between them and a net body that extends from the lowest wire rod along the ground outside the protected area.

特許文献３には、所定の間隔をもって配設された支柱を介して網状体を張りめぐらしてなる侵入防止柵であって、前記網状体は、地面に接する部分からはじまり地上７０センチメートル乃至９０センチメートルの高さまでを覆う亀甲金網と、該亀甲金網のすぐ上からはじまり、地上１８０センチメートル乃至２００センチメートルの高さまでを覆う格子型金網とからなることを特徴とする侵入防止柵が開示されている。そして、特許文献３には、鉄線１５は、より合わせ部Ａにおいては鉄線１６と三回より合わせられ、よりあわせ部Ｅにおいては反対側の隣り合う鉄線１４と三回より合わせられる、旨が開示されている（特許文献３の段落［００１６］、図３参照）。この三回より合わせとは、鉄線同士が１回転半撚り合わされることを指していることから、特許文献３には、鉄線同士が１回転半撚り合わされた亀甲金網が開示されている。 Patent Document 3 discloses an intrusion prevention fence formed by stretching a net-like body through posts arranged at predetermined intervals, wherein the net-like body is 70 to 90 cm above the ground starting from a portion in contact with the ground. Disclosed is an intrusion prevention fence characterized by comprising a tortoiseshell wire mesh covering up to a height of 100 meters and a grid wire mesh starting from just above the tortoiseshell wire mesh and covering to a height of 180 to 200 cm above the ground. there is Patent Document 3 discloses that the iron wire 15 is twisted three times with the iron wire 16 at the twisted portion A, and is twisted three times with the adjacent iron wire 14 on the opposite side at the twisted portion E. (Paragraph [0016] of Patent Document 3, see FIG. 3). Since the three-fold twisting means that the iron wires are twisted one and a half turns, Patent Document 3 discloses a tortoiseshell wire mesh in which the iron wires are twisted one and a half turns.

ところで、侵入防止柵は、屋外に設置されるものであり、野生動物等により容易に破損してしまうため、補修の容易性が求められる。また、野生動物の中でも特にシカやイノシシ等の大型動物が人工設備に侵入した場合、大きな事故や高価な機器の破損等を引き起こし、被害の規模が一層大きくなる。一方で、タヌキ等の小型動物が侵入したとしても被害は大きなものとならず、むしろ、小型動物の侵入まで防止してしまうと生態系へ影響を及ぼすこととなる。このため、大型動物については、その侵入を防止し、小型動物については、生態系への影響を低減させるため自由に往来できるようにして、生態系への影響を低減させる侵入防止柵が求められている。 Intrusion prevention fences, which are installed outdoors, are easily damaged by wild animals and the like, and thus are required to be easily repairable. In addition, when wild animals, especially large animals such as deer and wild boar, intrude into artificial facilities, they can cause major accidents and breakage of expensive equipment, resulting in further damage. On the other hand, even if a small animal such as a raccoon dog invades, the damage will not be great. For this reason, intrusion prevention fences that reduce the impact on the ecosystem by preventing the entry of large animals and allowing the free movement of small animals to reduce the impact on the ecosystem are required. ing.

樹脂製の網の場合、大型動物と小型動物を対象とした１００ｍｍ以下の網目のもの、大型動物を対象とした１５０ｍｍ～２００ｍｍの網目のものが用いられるものの、樹脂製の網は、破損しやすいという問題点がある。そして、樹脂製の網が破損した場合、部分補修が困難であり、網全体を交換しなくてはならず、容易に補修することができないという問題点がある。 In the case of resin nets, meshes of 100 mm or less are used for large and small animals, and meshes of 150 mm to 200 mm are used for large animals, but resin nets are easily damaged. There is a problem. In addition, when the resin net is damaged, it is difficult to partially repair it, and the entire net must be replaced, which makes it difficult to repair.

溶接金網の場合、溶接金網の重量が重く、そもそも持ち運びを容易に行うことができないという問題点がある。加えて、破損した溶接金網を補修する場合、設置される場所が野山等の自然環境であることから、現場溶接ができない。このため、網全体を交換しなくてはならず、容易に補修することができないという問題点がある。 In the case of the welded wire mesh, there is a problem that the weight of the welded wire mesh is heavy and it cannot be easily carried in the first place. In addition, when repairing a damaged welded wire mesh, it is not possible to perform on-site welding because the installation location is in a natural environment such as hills and fields. Therefore, the entire network must be replaced, and there is a problem that it cannot be easily repaired.

特許文献１～３の開示技術は、破損してほつれた場合であっても、現場で撚り合わせられるため、補修には適している。しかしながら、特許文献１～３の隔網材等の亀甲金網は、線材同士が１回転半しか撚り合わされていない。そして、亀甲金網の網目の大きさは、日本国内において最大でも６０ｍｍ、外国において最大でも１００ｍｍであるのが現状である。このため、網目の寸法が小さく、大型動物だけでなく小型動物の侵入も防止してしまい、生態系への影響を低減させることができないという問題点がある。加えて、線材同士が１回転半撚り合わされた網目の寸法を単に大きくしただけでは、容易に面外方向に変形が生じてしまい、金網自体の形状を保持できないという問題点がある。また、動物が通過しようとしたときには、容易に網目が面内方向に拡がるように変形してしまい、ほつれ等を引き起こす問題点がある。したがって、線材同士が１回転半撚り合わされた網目では、その寸法を単に大きくすることはできない。 The techniques disclosed in Patent Literatures 1 to 3 are suitable for repairing even if they are damaged and frayed, because they can be twisted together on site. However, in the tortoiseshell wire nettings such as the partition net materials of Patent Documents 1 to 3, the wire rods are twisted together only one and a half turns. At present, the mesh size of the tortoiseshell wire mesh is 60 mm at maximum in Japan and 100 mm at maximum in foreign countries. For this reason, the size of the mesh is small, and not only large animals but also small animals are prevented from entering, and there is a problem that the influence on the ecosystem cannot be reduced. In addition, simply increasing the size of the mesh formed by twisting the wire rods together by one and a half turns easily causes deformation in the out-of-plane direction, resulting in the problem that the shape of the wire mesh itself cannot be maintained. In addition, when an animal tries to pass through the mesh, the mesh is easily deformed so as to expand in the in-plane direction, causing fraying or the like. Therefore, it is not possible to simply increase the size of a mesh in which wires are twisted one and a half turns.

そこで、本発明は、上述した問題点に鑑みて案出されたものであり、その目的とするところは、持ち運びと補修を容易に行うことができ、形状を保持することができ、生態系への影響を低減させることが可能となる侵入防止柵用面材及び侵入防止柵を提供することにある。 Therefore, the present invention has been devised in view of the above-mentioned problems, and its purpose is to facilitate transportation and repair, maintain its shape, and contribute to ecosystems. To provide an intrusion prevention fence face material and an intrusion prevention fence capable of reducing the influence of

以下、本発明を適用した侵入防止柵用面材及び侵入防止柵を実施するための形態について、図面を参照しながら詳細に説明する。 EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing the surface material for intrusion prevention fences and the intrusion prevention fence which applied this invention is demonstrated in detail, referring drawings.

図１は、実施形態における侵入防止柵用面材１及び侵入防止柵１０の一例を示す正面図である。図２は、実施形態における侵入防止柵用面材１の一例を示す正面図である。 FIG. 1 is a front view showing an example of an intrusion prevention fence panel 1 and an intrusion prevention fence 10 according to the embodiment. FIG. 2 is a front view showing an example of the face member 1 for an intrusion prevention fence according to the embodiment.

侵入防止柵１０は、大型の野生動物の侵入を防止し、小型の野生動物が自由に往来できるものである。大型の野生動物としては、例えばシカやイノシシ等が該当する。小型の野性動物としては、例えばタヌキ、アライグマ、ハクビシン、イタチ、ネズミ、キツネ等が該当する。 The intrusion prevention fence 10 prevents large wild animals from entering and allows small wild animals to freely come and go. Examples of large wild animals include deer and wild boars. Examples of small wild animals include raccoon dogs, raccoons, palm civets, weasels, mice, and foxes.

侵入防止柵１０は、互いに離間して配置されて上下方向Ｚに延びる複数の支柱８と、隣り合う２本の支柱８、８に架設される侵入防止柵用面材１と、を備える。支柱８は、鋼管、Ｌ形のアングル材等が用いられればよい。 The intrusion prevention fence 10 includes a plurality of posts 8 spaced apart from each other and extending in the vertical direction Z, and an intrusion prevention fence face member 1 constructed over two adjacent posts 8, 8. - 特許庁A steel pipe, an L-shaped angle member, or the like may be used for the strut 8 .

侵入防止柵用面材１は、略六角形状に形成される網目部２を複数備える。侵入防止柵用面材１は、面内方向が上下方向Ｚに沿って配置され、地面Ｇに対して略垂直に配置される。また、侵入防止柵用面材１は、上端部１ａと下端部１ｂとに、上下方向Ｚに直交する横方向Ｘに平行に延びる鋼線等で構成される耳線６を更に備える。侵入防止柵用面材１は、側端部１ｃが支柱８に取り付けられる。なお、侵入防止柵用面材１は、面内方向が上下方向Ｚに対して傾斜して配置されてもよい。 The intrusion prevention fence face material 1 includes a plurality of mesh parts 2 formed in a substantially hexagonal shape. The surface material 1 for an intrusion prevention fence is arranged so that the in-plane direction is along the up-down direction Z, and is arranged substantially perpendicular to the ground G. As shown in FIG. Further, the intrusion prevention fence face material 1 further includes selvedge wires 6 made of steel wires or the like extending parallel to the lateral direction X orthogonal to the vertical direction Z at the upper end portion 1a and the lower end portion 1b. The side end portion 1c of the intrusion prevention fence panel 1 is attached to the post 8 . In addition, the surface material 1 for an intrusion prevention fence may be arranged such that the in-plane direction is inclined with respect to the vertical direction Z.

網目部２は、２本の線材３１、３１が２回転半撚り合わされる撚り部３を一対有する。本発明では、網目部２は、２本の線材３１、３１が２回転半以上撚り合わされる撚り部３を一対有していればよい。例えば、撚り部３は、２本の線材３１、３１が３回転半撚り合わされてもよいし、撚り部３は、２本の線材３１、３１が４回転半撚り合わされてもよい。 The mesh portion 2 has a pair of twisted portions 3 in which two wire rods 31, 31 are twisted two and a half turns. In the present invention, it suffices for the mesh portion 2 to have a pair of twisted portions 3 in which two wire rods 31, 31 are twisted two and a half turns or more. For example, the twisting part 3 may be formed by twisting two wires 31, 31 three and a half turns, or the twisting part 3 may be formed by twisting two wires 31, 31 four and a half turns.

線材３１は、例えば鋼製等の金属製の線材であり、外径が１．０ｍｍ以上３．０ｍｍ以下であることが好ましい。線材３１は、外径が１．０ｍｍ未満の場合、径が細すぎてすぐに切断されるおそれや、面外変形しやすく形状を保持しにくくなるおそれがある。また、線材３１は、外径が３．０ｍｍ超の場合、径が太すぎて撚り部３を形成しづらい。このため、線材３１は、外径が１．０ｍｍ以上３．０ｍｍ以下であることが好ましい。 The wire rod 31 is, for example, a wire rod made of metal such as steel, and preferably has an outer diameter of 1.0 mm or more and 3.0 mm or less. If the outer diameter of the wire rod 31 is less than 1.0 mm, the wire rod 31 may be too thin to be cut immediately, or may be easily deformed out of plane and difficult to maintain its shape. Moreover, when the outer diameter of the wire rod 31 exceeds 3.0 mm, the wire rod 31 is too thick to form the twisted portion 3 . For this reason, the wire 31 preferably has an outer diameter of 1.0 mm or more and 3.0 mm or less.

線材３１は、例えば、線径１．８ｍｍの金属製の芯線材に低密度ポリエチレン等の樹脂製材等が被覆されて外径が２．６ｍｍの被覆線材が用いられる。線材３１として被覆線材が用いられる場合、例えば引張強度が４００Ｎ／ｍｍ2～４５０Ｎ／ｍｍ2程度の軟鋼線材や、引張強度が８５０Ｎ／ｍｍ2～９５０Ｎ／ｍｍ2程度の硬鋼線材が用いられる。線材３１は、例えば外径２．０ｍｍの溶融亜鉛めっき等が施されためっき線材が用いられる。線材３１は、例えば外径２．０ｍｍのステンレス線材が用いられる。 The wire 31 is, for example, a coated wire having an outer diameter of 2.6 mm, which is obtained by coating a metal core wire having a wire diameter of 1.8 mm with a resin material such as low-density polyethylene. When a coated wire rod is used as the wire rod 31, for example, a mild steel wire rod having a tensile strength of about 400 N/mm 2 to 450 N/mm 2 or a hard steel wire rod having a tensile strength of about 850 N/mm 2 to 950 N/mm 2 is used. As the wire rod 31, for example, a plated wire rod having an outer diameter of 2.0 mm and subjected to hot-dip galvanization or the like is used. A stainless steel wire having an outer diameter of 2.0 mm, for example, is used as the wire 31 .

一対の撚り部３、３は、互いに同一方向に延びて離間して配置される。撚り部３の延伸方向Ｐは、上下方向Ｚに直交する横方向Ｘに平行である。 The pair of twisted portions 3, 3 are arranged to extend in the same direction and be separated from each other. The extending direction P of the twisted portion 3 is parallel to the lateral direction X orthogonal to the vertical direction Z. As shown in FIG.

撚り部３の延伸方向Ｐに沿う撚り部３の中心線Ｃとしたとき、一対の撚り部３、３のそれぞれの中心線Ｃ、Ｃの間が離間距離Ｌとなる。本発明では、一対の撚り部３、３の離間距離Ｌは、１１０ｍｍ以上２００ｍｍ以下であればよい。一対の撚り部３、３の離間距離Ｌが１１０ｍｍ未満の場合、小型の野性動物が網目部２を通過することができない。また、一対の撚り部３、３の離間距離Ｌが２００ｍｍ以上の場合、大型の野性動物まで通過してしまう虞がある。このため、本発明では、一対の撚り部３、３の離間距離Ｌは、１１０ｍｍ以上２００ｍｍ以下であればよい。また、一対の撚り部３、３の離間距離Ｌが１２０ｍｍである場合、網目部２の形状が略正六角形状にし易く、工場での侵入防止柵用面材１の製作性を向上させることができる。また、網目部２の形状が略正六角形状であることで、形状の安定性を向上させることができる。このため、一対の撚り部３、３の離間距離Ｌが１２０ｍｍであることが好ましい。 Assuming that the center line C of the twisted portion 3 along the extending direction P of the twisted portion 3 is taken, the separation distance L is between the center lines C, C of the pair of twisted portions 3, 3, respectively. In the present invention, the separation distance L between the pair of twisted parts 3, 3 should be 110 mm or more and 200 mm or less. If the distance L between the pair of twisted parts 3, 3 is less than 110 mm, a small wild animal cannot pass through the mesh part 2. Also, if the distance L between the pair of twisted parts 3, 3 is 200 mm or more, there is a risk that even a large wild animal will pass through. Therefore, in the present invention, the separation distance L between the pair of twisted portions 3, 3 should be 110 mm or more and 200 mm or less. Further, when the separation distance L between the pair of twisted parts 3, 3 is 120 mm, the shape of the mesh part 2 can be easily made into a substantially regular hexagonal shape, and the manufacturability of the face material 1 for the intrusion prevention fence at the factory can be improved. can. Moreover, since the mesh portion 2 has a substantially regular hexagonal shape, it is possible to improve the stability of the shape. Therefore, it is preferable that the distance L between the pair of twisted portions 3, 3 is 120 mm.

侵入防止柵用面材１は、ロール状に巻くことができる。このため、持ち運びを容易に行うことが可能となる。侵入防止柵用面材１を巻く際には、撚り部３の延伸方向Ｐに向けて巻くことが好ましい。 The intrusion prevention fence face material 1 can be wound into a roll. For this reason, it becomes possible to carry easily. When winding the face material 1 for an intrusion prevention fence, it is preferable to wind in the extension direction P of the twisted portion 3 .

侵入防止柵１０を組み立てる際には、先ず、複数の支柱８、８を互いに離間させて、地面Ｇに立設する。そして、ロール状に巻かれた侵入防止柵用面材１を展開して、撚り部３の延伸方向Ｐを横方向Ｘに平行となるように配置する。そして、侵入防止柵用面材１の側端部１ｃを支柱８、８に取り付け、侵入防止柵用面材１を支柱８、８間に架設する。 When assembling the intrusion prevention fence 10, first, a plurality of posts 8, 8 are spaced apart from each other and erected on the ground G. - 特許庁Then, the intrusion prevention fence face material 1 wound in a roll shape is unfolded and arranged so that the extension direction P of the twisted part 3 is parallel to the lateral direction X. - 特許庁Then, the side ends 1c of the intrusion prevention fence panel 1 are attached to the supports 8 and 8, and the intrusion prevention fence panel 1 is constructed between the supports 8 and 8.
