Abstract

<P>PROBLEM TO BE SOLVED: To provide an anchor pin which is decomposed at the same time when embedded in soil together with netted materials to eliminate the need for collection without generating harmful gas upon disposal together with the netted materials or upon combustion in a similar way to that of the netted materials when particularly using the netted materials to decompose themselves in soil, considering that a lighter pin is desired to appear because a conventional iron anchor pin is very heavy to require much transporting and collecting labor and much transport cost as well as requiring troublesome fixing work for the deployed netted materials and troublesome pin collecting work. <P>SOLUTION: The anchor pin formed of base paper using natural fibers including cotton pulp and woody pulp as main raw materials comprises a body, a netted material locking clasp section on the upper part thereof, and a protruded section at the front end of the lower part thereof. The base paper using the natural fibers as the main raw materials is vulcanized fibers and 2-12 mm in thickness. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、天然繊維を主体として構成された展張物固定用アンカーピンに関するものである。   The present invention relates to an anchor pin for fixing a stretched article mainly composed of natural fibers.

従来一般に使用されているアンカーピンは、鉄系線材を用いて、たとえば図3に示すように鉄系線材の本体部1の上部に係止用鉤部2を設け、下部の先端に土中に打ち込み固定できるような突起部3を設けたものが多く用いられてきた。この鉄系線材を用いたアンカーピンは、強度が強く、テントの固定や農業用網状体や、傾斜地の崩壊防止用の植生用ネットの固定などに用いられることは勿論であるが、重量が非常に重いことと、使用する個数も多いことから、使用のつど施工する現地に運搬したり、回収するのに重量の影響で大変負担がかかるという問題があった。   An anchor pin generally used in the prior art uses an iron-based wire, and as shown in FIG. 3, for example, an anchoring hook 2 is provided on the upper part of the main body 1 of the iron-based wire, and the lower end is placed in the soil. Many are provided with protrusions 3 that can be driven and fixed. The anchor pin using this iron-based wire has high strength, and of course it is used for fixing tents, agricultural nets, and vegetation nets for preventing collapse of slopes, but it is very heavy. Because of its heavy weight and the large number of items it uses, there is a problem that it is very burdensome due to the weight of the product to be transported to the site where it is used and recovered.

また、本発明者らは、従来用いられている可燃性のポリエチレンもしくはポリプロピレンなどの可燃性材料からなる網状体は勿論、本発明者が特願2002−280667号にて提案するように木材パルプから製造された紙ひも網状体(ネット)の引止め固定に際して、軽量で、反復使用可能で、必要に応じて燃焼処理しても有害ガスの発生がなく、処分しやすいことは勿論であるが、廃棄に際して地中埋設しても微生物の作用により、自然に土の中に還元するアンカーピンを生み出したものである。   In addition, the present inventors have used not only reticulated bodies made of combustible materials such as combustible polyethylene or polypropylene, but also wood pulp as proposed by the present inventors in Japanese Patent Application No. 2002-280667. Of course, it is lightweight, can be used repeatedly, and does not generate harmful gas even if it is burned if necessary, and it is easy to dispose of it when securing the manufactured paper string net (net). It is an anchor pin that is naturally reduced into the soil by the action of microorganisms even when buried underground.

解決しようとする問題点は、従来の鉄系金属ピンの重量が非常に大きく運搬回収に多大の労力、運送費用がかかることと、展張された網状物などのアンカーピンによる固定作業が大変であり、ピンの回収作業も大変であるので、軽量なピンの出現が待望されていたことと、特に網状物自身が土中で分解可能なものを用いる場合、或いはポリエチレンもしくはポリプロピレンなどの燃焼時有害ガスを発生しないものを用いる場合、一緒に燃焼しても有害ガスを発生せず、更には天然セルロース系の網状体の場合など一緒に土中に埋設しても同時に分解され、回収する必要がないかあるいは回収後無公害で、処理の容易なアンカーピンの出現が待望されていた。   The problems to be solved are that the weight of conventional iron-based metal pins is very large, and it takes a lot of labor and transportation costs for transportation and collection, and fixing work with anchor pins such as stretched nets is difficult. The recovery of the pin is also difficult, so the appearance of a lightweight pin was awaited, and especially when using a net that can be decomposed in the soil itself, or harmful gases during combustion such as polyethylene or polypropylene In the case of using a material that does not generate toxic gas even if it is burned together, and even if it is embedded in the soil together, such as in the case of a natural cellulosic network, it does not need to be decomposed and recovered at the same time. Alternatively, there has been a long-awaited appearance of anchor pins that are pollution-free and easy to process.

本発明は、上記の実情に鑑みて鋭意検討の結果生み出されたもので、その概要は、天然繊維を主原料とする原紙からなり、本体部の上部に展張物の係止用鉤部を有し、下部先端に突起部を設けたことを特徴とするアンカーピン(請求項1)であり、天然繊維を主原料とする原紙がバルカナイズドファイバであることを特徴とする請求項1に記載のアンカーピン(請求項2)であり、天然繊維を主原料とする原紙が、繊維材料を抄造、圧縮、乾燥、断裁加工の手段により製造されたものであることを特徴とする請求項1に記載のアンカーピン(請求項3)である。
また、厚みが2〜12mmであることを特徴とする請求項1に記載のアンカーピン(請求項4)であり、植生用網状体に使用することを特徴とする請求項1に記載のアンカーピン(請求項5)である。
The present invention was created as a result of intensive studies in view of the above circumstances, and its outline is made of a base paper made of natural fibers as a main raw material, and has a hook for locking a stretched product at the top of the main body. The anchor pin according to claim 1, wherein a protrusion is provided at a lower end, and the base paper made of natural fiber as a main raw material is a vulcanized fiber. 2. The base paper according to claim 1, wherein the base paper is a pin (Claim 2) and is made of natural fiber as a main raw material by means of papermaking, compression, drying, and cutting. It is an anchor pin (claim 3).
The anchor pin according to claim 1, wherein the anchor pin has a thickness of 2 to 12 mm (claim 4) and is used for a vegetation net. (Claim 5).

本発明で、天然繊維と称するものは、綿(コットン繊維)、木材繊維(木材パルプから得られる線繊維)等の植物繊維及び絹、羊毛等の動物繊維を含むが、アンカーピンとして廉価で好適に使用される繊維は、植物繊維であり、この植物性繊維を原料とし、膠化させたバルカナイズドファイバが好適に使用される。なお、バルカナイズドファイバの具体例については後述する。   In the present invention, natural fibers include plant fibers such as cotton (cotton fibers) and wood fibers (wire fibers obtained from wood pulp) and animal fibers such as silk and wool, but are inexpensive and suitable as anchor pins. The fiber used in the above is a vegetable fiber, and a vulcanized fiber obtained by using the vegetable fiber as a raw material and glued is preferably used. A specific example of the vulcanized fiber will be described later.

本発明のアンカーピンが好適に使用される植生用網状体は、山腹等の自然傾斜面や道路開発に伴って形成された切取り法面あるいは盛土法面等の人工斜面における雨水または風等による土壌の浸食流亡を防止する手段として、前記斜面等に敷設するものである。この場合、緑化工法の一つとして植生用網状体に植物種子を担持して植生機能を持たせることも可能である。当該植生用網状体の素材としては、天然セルロース系パルプを主原料とする原紙からなる紙紐を編成したシート状網状体、ポリエチレン、ポリプロピレンおよびナイロン等の合成高分子繊維を編成したシート状網状体、ジュート繊維、椰子繊維、木綿繊維、竹繊維、羊毛、アセテート繊維、麻等の腐朽性繊維を編成したシート状網状体および金網等が挙げられる。これらの素材は、各々単独で網状に編成されてもよいし、複数を絡合させた絡合体に編成して形成されていてもよい。また、これらのシート状網状体は、単一シートでもよいし、複数枚積層して形成されたものでもよい。
本発明のアンカーピンは、これらの網状体の中でも特に天然セルロース系パルプからなる紙紐網状体や腐朽性繊維の網状体と共用した場合、土壌に埋設して放置した際、網状体とともに土中の微生物により分解されるので、回収の手間が省け好適である。
The vegetation network in which the anchor pin of the present invention is preferably used is a natural slope such as a mountainside or soil caused by rainwater or wind on an artificial slope such as a cut slope or a bank slope formed with road development. As a means for preventing the erosion runoff, it is laid on the slope or the like. In this case, as one of the greening methods, it is possible to provide a vegetation function by supporting plant seeds on a vegetation net. The material for the vegetation network is a sheet network obtained by knitting a paper string made of a raw paper mainly made of natural cellulose pulp, or a sheet network obtained by knitting synthetic polymer fibers such as polyethylene, polypropylene and nylon. , Jute fiber, cocoon fiber, cotton fiber, bamboo fiber, wool, acetate fiber, sheet-like nets knitted with decaying fibers such as hemp, and wire nets. Each of these materials may be knitted into a net shape alone, or may be formed by knitting into an entangled body in which a plurality of materials are entangled. Moreover, these sheet-like nets may be a single sheet or may be formed by laminating a plurality of sheets.
The anchor pin of the present invention, among these nets, especially when used with a paper string net made of natural cellulosic pulp or a net of a decaying fiber, when buried and left in the soil, Therefore, it is preferable to save the labor of collection.

本発明のアンカーピンは、コットンパルプや木材パルプ等の天然繊維を主原料とする原紙からなるので、一定の幅と厚みの積層体とし、所定の形状に切削すればいかなる形状、寸法設計のもでも容易に製造することができ、多量生産できるので、コストも比較的安価であり、軽量で、運搬が容易で取り付けおよび取り外し作業が容易で、樹脂含浸で強度を高めることができ、この樹脂として不燃性樹脂を含浸させた場合以外は、土中で微生物により容易に分解するので、土中で容易に分解する繊維質ネットなどの網状物と一緒に廃棄処理することもできる。又燃焼で廃棄処理をしても有害ガスを発生することはない。   Since the anchor pin of the present invention is made of a base paper made mainly of natural fibers such as cotton pulp and wood pulp, it is a laminated body having a certain width and thickness, and can be designed in any shape and size as long as it is cut into a predetermined shape. However, since it can be easily manufactured and mass-produced, the cost is relatively low, it is lightweight, easy to carry, easy to install and remove, and can be increased in strength by resin impregnation. Except when impregnated with a non-flammable resin, it is easily decomposed by microorganisms in the soil, so that it can be disposed of together with a net such as a fibrous net that easily decomposes in the soil. Also, no harmful gas is generated even if it is disposed of by combustion.

本発明で用いられる天然繊維を主原料とする原紙は、代表的にはバルカナイズドファイバ(膠化繊維板)が知られている。具体的には、植物繊維をセルロース表面膨潤剤によって、膨潤させた状態で圧着した後該膨潤剤を除去したものである。代表的なものは、塩化亜鉛膨潤剤を用いたもので、たとえばファイバ原紙を液温35℃〜55℃で、濃度68〜72Beの濃厚塩化亜鉛溶液に複数枚浸漬して積層させ熟成後塩化亜鉛を洗浄除去し、乾燥することにより所定の厚さのものを得ることができる。
このようにして得られたバルカナイズドファイバは、好ましくは厚さ2.0〜12mmより好ましくは2.5〜6.0mmで、密度1.0g/cm以下層間剥離強度10〜20N/m以上、引張強度80〜100Mpaのものが得られる。その製造方法の一例は、綿ラグパルプまたはリンターパルプの粘度水準をタッピー式粘度で6cps以上90cps程度に高めた原料を抄紙してバルカナイズドファイバ原紙として、この原紙をたとえば常温プラズマ処理した後塩化亜鉛溶液に浸漬して熟成、水洗、乾燥して製造される。バルカナイズドファイバの原料としては、針葉樹クラフト晒パルプ(NBKP)又は広葉樹クラフト晒パルプ(LBKP)を用いることにより通常の紙同様に容易に製造することができる。
A vulcanized fiber (glued fiber board) is typically known as a base paper mainly composed of natural fibers used in the present invention. Specifically, after the plant fiber is pressure-bonded in a swollen state with a cellulose surface swelling agent, the swelling agent is removed. A typical example is one using a zinc chloride swelling agent. For example, a plurality of sheets of fiber base paper are immersed in a concentrated zinc chloride solution having a liquid temperature of 35 ° C. to 55 ° C. and a concentration of 68 to 72 Be, and ripened, and then zinc chloride is aged. A product having a predetermined thickness can be obtained by washing away and drying.
The vulcanized fiber thus obtained preferably has a thickness of 2.0 to 12 mm, more preferably 2.5 to 6.0 mm, a density of 1.0 g / cm 3 or less , and a delamination strength of 10 to 20 N / m or more. A tensile strength of 80 to 100 MPa is obtained. An example of the production method is that a raw material in which the viscosity level of cotton rug pulp or linter pulp is increased to 6 cps or more and about 90 cps by tappy type viscosity is made into a vulcanized fiber base paper. It is produced by dipping, aging, washing with water and drying. As a raw material for vulcanized fiber, softwood kraft bleached pulp (NBKP) or hardwood kraft bleached pulp (LBKP) can be used to easily produce the same as ordinary paper.

更に、本発明は、天然繊維を主原料とする原紙が、木材繊維に代表される植物繊維や動物繊維等の繊維材料を抄造、圧縮、乾燥、断裁加工の手段により製造された繊維ボード状のアンカーピンである。該繊維ボードとしては、例えば北越製紙社製の「商品名:PASCO(パスコ)」が本発明に適用できる。この場合、抄造に使用される原紙の繊維材料としては古紙を使用することも可能である。また、抄紙後の圧縮工程は、コールドプレス、ホットプレスなど状況に応じて選択することができる。また、アンカーピンの形状に裁断した後、必要に応じて光沢加工を施すことができる。   Furthermore, the present invention is a fiberboard-like base paper made of natural fibers as a main raw material, produced by means of papermaking, compression, drying, and cutting processing of fiber materials such as plant fibers and animal fibers typified by wood fibers. It is an anchor pin. As the fiber board, for example, “trade name: PASCO” manufactured by Hokuetsu Paper Co., Ltd. can be applied to the present invention. In this case, it is possible to use waste paper as the fiber material of the base paper used for papermaking. Moreover, the compression process after papermaking can be selected according to conditions, such as a cold press and a hot press. Moreover, after cutting into the shape of an anchor pin, gloss processing can be performed as needed.

図1および図2は、本発明のアンカーピンの一例の斜視図であり、図1は、本体1の上部に一個のク字状の係止用鉤部2を設けて網などの引き止め部を引っ掛けて係止するようになっている。下端は大地への突き刺用突起部3である。図2は、他の実施例で、図1よりもやや本体1が幅広で、厚さの厚いもので構成されており、同一部分には同一符号が付されている。なお、図示していないが、上部の係止用鉤部2はク字状に限定されるものではなく、曲線状であってもよく、さらに必要に応じて左右に2個設けて網などの引き止めるようにしてもよい。下端はいずれも大地への突き刺し固定する突起部である。   1 and 2 are perspective views of an example of the anchor pin according to the present invention. FIG. 1 is a plan view in which a single hook-shaped locking collar portion 2 is provided on the upper portion of the main body 1 and a retaining portion such as a net is provided. It is designed to be hooked and locked. The lower end is a protrusion 3 for piercing the ground. FIG. 2 shows another embodiment in which the main body 1 is slightly wider and thicker than that in FIG. 1, and the same parts are denoted by the same reference numerals. Although not shown in the drawing, the upper locking collar 2 is not limited to a U-shape, and may be a curved shape. You may make it stop. Each of the lower ends is a protrusion that pierces and fixes to the ground.

本発明のアンカーピンは、上記のように材料が主として天然繊維から構成されているので、鉄系の従来のアンカーピンよりも遥かに軽量であるにもかかわらず、相当な強度を有し、通常の網状物は勿論テントなどの引き止めにも使用することができ、しかも万一廃棄処分する場合、有害ガスを発生することなく燃焼させることができ、さらには土中に埋設した場合でも微生物の作用により、自然に分解するので自然分解可能な網状物と一緒に放置したり、土の中に埋設するという簡単な処分が可能であり、また、網状物などの展張施工の前後に運搬しても比較的軽量で、施工も鉄系アンカーピンより軽いので作業が容易である。   As described above, the anchor pin of the present invention is composed mainly of natural fibers, and thus has a considerable strength despite being much lighter than conventional iron-based anchor pins. Of course, the nets can be used to hold tents, etc., and if they are to be disposed of, they can be burned without generating harmful gases. Because it decomposes naturally, it can be easily disposed of with a releasable reticulated material or embedded in the soil, and it can also be transported before and after the construction of a reticulated material. Work is easy because it is relatively light and lighter than iron anchor pins.

本発明は、前述のような植生用網状体の固定以外にテント等の野外レジャー製品の固定用、農業用簡易被覆ネットの固定用、建築用網状体の固定等多数のアンカーピンによる固定を必要とする用途に適用できる。
本発明のアンカーピンは、天然繊維を主原料にしているので軽量であるという利点があり、運搬に際して容易である。また、使用後廃却する場合、燃焼しても容易に有害ガスを発生することなく処分することが出きる。更に又、使用に際して天然セルロース系パルプからなる紙紐網状体や腐朽性繊維の網状体と共用した場合、土中に埋設して放置した際、網状体と共に土中の微生物により分解されるので、環境への貢献も大きい。
In addition to fixing the vegetation net as described above, the present invention requires fixing by a number of anchor pins, such as fixing outdoor leisure products such as tents, fixing simple agricultural nets, and fixing building nets. It can be applied to
The anchor pin of the present invention has an advantage that it is lightweight because it is made of natural fiber as a main raw material, and is easy to carry. Moreover, when disposing after use, it can be easily disposed of without generating harmful gas even if it is burned. Furthermore, when used in combination with a paper string network made of natural cellulosic pulp or a network of decaying fibers when used, it is decomposed by microorganisms in the soil together with the network when left buried in the soil. The contribution to the environment is also great.
