防護ネット１０は、図１及び図２に示すように、樹木１０１が生えている山や森林の斜面１００を防護するための土木用設備品である。防護ネット１０は、ネット状に形成されている複合繊維部材１１と、固定手段１２と、を有する。   As shown in FIGS. 1 and 2, the protection net 10 is a civil engineering equipment for protecting a slope 100 of a mountain or a forest where trees 101 grow. The protection net 10 has a composite fiber member 11 formed in a net shape and fixing means 12.

複合繊維部材１１は、線状又は棒状の部材であり、本実施の形態１では、第１の繊維材と第２の繊維材とが編み込まれたり、織り込まれたりして形成された繊維束である。   The composite fiber member 11 is a linear or rod-shaped member. In Embodiment 1, the composite fiber member 11 is a fiber bundle formed by weaving or weaving the first fiber material and the second fiber material. is there.

第１の繊維材は、ポリエステル系の樹脂繊維であり、複合繊維部材１１の主繊維として構成されている。具体的には、第１の繊維材の樹脂繊維は、例えば、ＰＥＴ（Polyethylene Terephthalate）等である。しかしながら、これに限られない。第１の繊維材の樹脂繊維は、第２の繊維材の素材よりも融点の高い素材であれば、ＰＥＴ以外の素材、例えば、アラミド繊維であってもよい。   The first fiber material is a polyester-based resin fiber, and is configured as a main fiber of the composite fiber member 11. Specifically, the resin fiber of the first fiber material is, for example, PET (Polyethylene Terephthalate) or the like. However, it is not limited to this. The resin fiber of the first fiber material may be a material other than PET, for example, an aramid fiber, as long as the material has a higher melting point than the material of the second fiber material.

第２の繊維材は、ポリプロピレンやポリエチレンを含むオレフィン系の樹脂繊維であり、複合繊維部材１１の副繊維として構成されている。具体的には、第２の繊維材の樹脂繊維は、例えば、ＰＰ（polypropylene）等である。しかしながら、これに限られない。第２の繊維材の素材は、第１の繊維材の素材よりも融点の低い熱可塑性の素材であれば、ＰＰ以外の素材であってもよい。なお、第１の繊維材がポリエステル系の樹脂繊維である場合には、第２の繊維材は、オレフィン系の樹脂繊維であることが好ましく、第１の繊維材がアラミド繊維である場合には、第２の繊維材は、ポリエステル系の樹脂繊維であることが好ましい。   The second fiber material is an olefin-based resin fiber containing polypropylene or polyethylene, and is configured as an auxiliary fiber of the composite fiber member 11. Specifically, the resin fiber of the second fiber material is, for example, PP (polypropylene) or the like. However, it is not limited to this. The material of the second fiber material may be a material other than PP as long as it is a thermoplastic material having a lower melting point than the material of the first fiber material. In addition, when the first fiber material is a polyester resin fiber, the second fiber material is preferably an olefin resin fiber, and when the first fiber material is an aramid fiber. Preferably, the second fiber material is a polyester resin fiber.

複合繊維部材１１は、図３に示すように、略正方形の四角形部材１３となるように折り曲げられた状態で使用される。四角形部材１３の一辺は、例えば、０．５ｍである。折り曲げられた複合繊維部材１１によって囲われた空間には、樹木１０１が配置される。防護ネット１０は、複数の四角形部材１３を有しており、複数の四角形部材１３が組み合わされて、防護ネット１０を構成する。なお、線状の複合繊維部材１１の両側の端部１１ａ，１１ｂにジョイント部材１４を設けて、複合繊維部材１１を略正方形の四角形部材１３となるように折り曲げた後に、複合繊維部材１１の端部１１ａと端部１１ｂとをジョイント部材１４によって接続するようにしてもよい。具体的には、端部１１ａ、１１ｂに孔を形成し、Ｃ字形状のジョイント部材１４によって、端部１１ａ、１１ｂを引っ掛けるようにして、端部１１ａと端部１１ｂとを接続するようにしてもよい。
また、本実施の形態１においては、複合繊維部材１１の端部１１ａ，１１ｂは、四角形部材１３の一辺の中央近傍に配置されている。しかしながら、これに限られない。例えば、端部１１ａ，１１ｂは、図４に示すように、四角形部材１３の角部分近傍に配置されていてもよい。 As shown in FIG. 3, the composite fiber member 11 is used in a state where the composite fiber member 11 is bent so as to become a substantially square quadrangular member 13. One side of the square member 13 is, for example, 0.5 m. Trees 101 are arranged in a space surrounded by the folded composite fiber member 11. The protection net 10 has a plurality of square members 13, and the plurality of square members 13 are combined to form the protection net 10. Note that joint members 14 are provided at both ends 11 a and 11 b of the linear composite fiber member 11, and the composite fiber member 11 is bent into a substantially square quadrangular member 13. The portion 11a and the end 11b may be connected by the joint member 14. Specifically, holes are formed in the ends 11a and 11b, and the ends 11a and 11b are hooked by the C-shaped joint member 14 so that the ends 11a and 11b are connected to each other. Is also good.
In the first embodiment, the ends 11 a and 11 b of the composite fiber member 11 are arranged near the center of one side of the square member 13. However, it is not limited to this. For example, the end portions 11a and 11b may be arranged near the corners of the square member 13 as shown in FIG.

固定手段１２は、図１及び図２に示すように、防護ネット１０の防護対象である山や森林の斜面１００に固定するためのものである。固定手段１２は、補強材１２ａと支圧板１２ｂとを有する。   As shown in FIGS. 1 and 2, the fixing means 12 is for fixing the protection net 10 to a slope 100 of a mountain or forest to be protected. The fixing means 12 has a reinforcing member 12a and a supporting plate 12b.

補強材１２ａは、斜面１００の地盤に打ち付けられるロックボルトである。補強材１２ａは、地盤のすべり面１０２を貫通して配置されている。   The reinforcing member 12a is a lock bolt that is driven into the ground of the slope 100. The reinforcing member 12a is arranged so as to penetrate the slip surface 102 of the ground.

支圧板１２ｂは、補強材１２ａの頭部に設けられると共に、ネット状部材（複合繊維部材１１）を支持する。   The support plate 12b is provided on the head of the reinforcing member 12a and supports the net-shaped member (composite fiber member 11).

上述のように構成されている複合繊維部材１１は、以下のように製造される。   The composite fiber member 11 configured as described above is manufactured as follows.

先ず、最初の工程（準備工程）では、作業者は、第１の繊維材と、第１の繊維材の素材よりも融点の低い素材からなる第２の繊維材とを準備する。   First, in a first step (preparation step), an operator prepares a first fiber material and a second fiber material made of a material having a lower melting point than the material of the first fiber material.

続いて、次の工程（織編工程）では、第１の繊維材と第２の繊維材とを織編する。本実施の形態１では、第１の繊維材と第２の繊維材とをそれぞれ紐状に形成してから、これらの２本の紐状の部材を合撚して、２種の繊維材を含む１本の紐状部材（硬化前の複合繊維部材１１）を形成する。   Subsequently, in the next step (weaving and knitting step), the first fiber material and the second fiber material are woven and knitted. In the first embodiment, the first fiber material and the second fiber material are each formed into a string shape, and then these two string members are twisted to form two types of fiber materials. One string-shaped member (the composite fiber member 11 before curing) is formed.

続いて、次の工程（四角形部材形成工程）では、図３に示すように、２種の繊維材を含む１本の紐状部材（硬化前の複合繊維部材１１）を折り曲げて、複数の四角形部材１３を形成する。なお、この四角形部材形成工程は、第２の繊維材を硬化させる硬化工程の後に行ってもよい。ただし、硬化前のほうが複雑な形状にしやすいので、四角形部材形成工程は、第２の繊維材を硬化させる硬化工程の前に行うのが好ましい。   Subsequently, in the next step (square member forming step), as shown in FIG. 3, one string-like member (composite fiber member 11 before curing) including two types of fiber materials is bent to form a plurality of square members. The member 13 is formed. Note that this square member forming step may be performed after the curing step of curing the second fiber material. However, since it is easier to form a complicated shape before curing, it is preferable to perform the square member forming step before the curing step of curing the second fiber material.

続いて、次の工程（溶融工程）では、織編された紐状部材を加熱する。このとき、ＰＥＴからなる第１の繊維材を溶かさないようにしつつ、ＰＰからなる第２の繊維材のみを溶融させる。この溶融工程での加熱温度域は、１７０以上２５０℃以下の温度域であることが好ましい。しかしながら、これに限られない。溶融工程での加熱温度域は、第１の繊維材の素材及び第２の繊維材の素材に応じて、適宜、変更することが好ましい。   Subsequently, in the next step (melting step), the woven and knitted string-shaped member is heated. At this time, only the second fiber material made of PP is melted while the first fiber material made of PET is not melted. The heating temperature range in this melting step is preferably a temperature range of 170 to 250 ° C. However, it is not limited to this. It is preferable that the heating temperature range in the melting step is appropriately changed according to the material of the first fiber material and the material of the second fiber material.

続いて、次の工程（硬化工程）では、第２の繊維材を硬化させて、第１の繊維材に第２の繊維材を固着させる。第２の繊維材を硬化させることにより、柔らかい状態の紐状部材は、剛性を有し、強度の大きい線状又は棒状の複合繊維部材１１になる。   Subsequently, in the next step (curing step), the second fibrous material is cured to fix the second fibrous material to the first fibrous material. By hardening the second fibrous material, the string-like member in a soft state becomes a rigid or linear and bar-shaped composite fiber member 11 having high strength.

続いて、次の工程（ネット形成工程）では、図１及び図２に示すように、複数の四角形部材１３を組み合わせてネット状に形成する。これにより、防護ネット１０が完成する。   Subsequently, in the next step (net forming step), as shown in FIGS. 1 and 2, a plurality of square members 13 are combined to form a net. Thereby, the protection net 10 is completed.

なお、溶融工程の前に、ＰＰからなる第２の繊維材に、難燃剤を付加する工程を行ってもよい。   Note that, before the melting step, a step of adding a flame retardant to the second fiber material made of PP may be performed.

以上、説明したように、本実施の形態１においては、複合繊維部材１１は、融点の異なる２種の繊維材を含んで構成されている。そして、一方の繊維材のみを溶融させて、複合繊維部材１１を形成することが可能になる。このため、十分な強度を有しつつ、簡易な工程で製造可能な複合繊維部材１１及び防護ネット１０等を提供することができる。   As described above, in Embodiment 1, the composite fiber member 11 is configured to include two types of fiber materials having different melting points. Then, the composite fiber member 11 can be formed by melting only one of the fiber materials. For this reason, it is possible to provide the composite fiber member 11 and the protective net 10 which have sufficient strength and can be manufactured by a simple process.

また、本実施の形態１においては、複合繊維部材１１は、繊維材を含んで構成されているため、通常のロープで形成されている防護ネット１０に比べて、耐久性を向上させることができる。   Further, in the first embodiment, since the composite fiber member 11 is configured to include the fiber material, the durability can be improved as compared with the protection net 10 formed by a normal rope. .

また、金属からなる複合繊維部材１１を使用した防護ネット１０と比べて、本実施の形態１に係る複合繊維部材１１は錆びることがなく、結果として、防護ネット１０の耐久性を向上させることができる。金属からなる複合繊維部材１１を使用した防護ネット１０と比べて、防護ネット１０全体を軽くすることができ、防護ネット１０の取り扱いを容易にすることができると共に、山や森林の斜面１００への施工の作業効率を向上させることができる。   Further, compared with the protection net 10 using the composite fiber member 11 made of metal, the composite fiber member 11 according to the first embodiment does not rust, and as a result, the durability of the protection net 10 can be improved. it can. As compared with the protection net 10 using the composite fiber member 11 made of metal, the entire protection net 10 can be made lighter, the protection net 10 can be easily handled, and the slope 100 of the mountain or forest can be easily removed. Work efficiency of construction can be improved.

また、本実施の形態１においては、織編された複合繊維部材１１を加熱し、ＰＥＴからなる第１の繊維材を溶かさないようにしつつ、ＰＰからなる第２の繊維材のみを溶融させている。このため、射出成型や繊維シートを用いる方法により形成される複合繊維部材１１に比べて、本実施の形態１に係る複合繊維部材１１では、十分な強度を有しつつ、簡易な工程で製造することができる。   In the first embodiment, the woven and knitted composite fiber member 11 is heated to melt only the second fiber material made of PP while preventing the first fiber material made of PET from being melted. I have. For this reason, compared with the composite fiber member 11 formed by injection molding or a method using a fiber sheet, the composite fiber member 11 according to Embodiment 1 is manufactured by a simple process while having sufficient strength. be able to.

また、本実施の形態１においては、溶融させる第２の繊維材の量を調整することにより、第２の繊維材を硬化させた後の複合繊維部材１１の剛性を適宜設定することができる。結果として、複合繊維部材１１又は防護ネット１０の適用対象や設計の自由度を向上させることができる。   In the first embodiment, the rigidity of the composite fiber member 11 after the second fiber material is cured can be appropriately set by adjusting the amount of the second fiber material to be melted. As a result, it is possible to improve the application object and the design flexibility of the composite fiber member 11 or the protection net 10.

また、本実施の形態１においては、第２の繊維材に、難燃剤が付加されている。このため、防護ネット１０を山や森林の斜面１００に設置した場合の防護ネット１０の安全性を向上させることができる。   In Embodiment 1, a flame retardant is added to the second fiber material. For this reason, the safety of the protection net 10 when the protection net 10 is installed on the slope 100 of a mountain or forest can be improved.

以上、本発明の実施の形態１について説明したが、本発明は上記実施の形態によって限定されるものではない。   Although the first embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment.

例えば、本実施の形態１では、複合繊維部材１１は、２種の繊維材を含んで構成されている。しかしながら、これに限られない。複合繊維部材１１は、３種以上の繊維材を含んで構成されていてもよい。   For example, in the first embodiment, the composite fiber member 11 is configured to include two types of fiber materials. However, it is not limited to this. The composite fiber member 11 may include three or more types of fiber materials.

また、本実施の形態１では、複合繊維部材１１は、第１の繊維材と第２の繊維材とをそれぞれ紐状に形成してから、これらの２本の紐状の部材を合撚して形成されている。しかしながら、２本の紐状の部材を組み合わせる方法は、任意である。合撚して形成するのではなく、引き揃えで組み合わせてもよい。   Further, in the first embodiment, the composite fiber member 11 is formed by forming the first fiber material and the second fiber material into a string shape, respectively, and then twisting the two string members. It is formed. However, the method of combining the two string-shaped members is arbitrary. Instead of being formed by twisting, they may be combined by drawing.

また、複合繊維部材１１は、ロープ状、組紐状、及びベルト状のいずれの部材であってもよい。組紐状の場合、複合繊維部材１１は、第２の繊維材を融解させて硬化させると、第１の繊維材からなる芯部分と、第２の繊維材からなる鞘部分とを有する構造となる。この場合、例えば、芯部分の素材にアラミド繊維を用いて、鞘部分に融点の低い別の繊維材を用いることで、アラミド繊維の弱点である紫外線の対策を施すことができる。   Further, the composite fiber member 11 may be any of a rope shape, a braid shape, and a belt shape. In the case of a braided shape, when the second fiber material is melted and cured, the composite fiber member 11 has a structure having a core portion made of the first fiber material and a sheath portion made of the second fiber material. . In this case, for example, by using aramid fiber for the material of the core portion and using another fiber material having a low melting point for the sheath portion, it is possible to take measures against ultraviolet rays, which is a weak point of the aramid fiber.

また、本実施の形態１では、図１及び図２に示すように、複数の四角形部材１３を組み合わせてネット状に形成している。しかしながら、これに限られない。図５に示すように、四角形部材１３の端部に孔を形成し、その孔同士を金具１５で連結するようにして、四角形部材１３をネット状に形成してもよい。   In the first embodiment, as shown in FIGS. 1 and 2, a plurality of square members 13 are combined to form a net. However, it is not limited to this. As shown in FIG. 5, a hole may be formed at an end of the square member 13, and the holes may be connected to each other by a metal fitting 15, so that the square member 13 may be formed in a net shape.

また、本実施の形態１では、複合繊維部材１１を折り曲げて、複数の四角形部材１３を形成してから、複数の四角形部材１３を組み合わせてネット状に形成している。しかしながら、これに限られない。図６に示すように、四角形部材１３を作らずに、硬化前の複合繊維部材１１を結び合わせて、直接、複数の紐の結び目１６を有する柔らかいネット状に形成し、その後、硬化させてもよい。また、他の方法で、ネット状に形成してもよい。   In the first embodiment, the composite fiber member 11 is bent to form a plurality of square members 13, and then the plurality of square members 13 are combined to form a net. However, it is not limited to this.
