Description

本発明は、パイル間に砂などの充填材を充填してなる人工芝構造体に関し、さらに詳しく言えば、幼稚園や保育園の園庭に好ましく採用される人工芝構造体に関する。   The present invention relates to an artificial turf structure in which a filler such as sand is filled between piles. More specifically, the present invention relates to an artificial turf structure preferably employed in a kindergarten or nursery school garden.

パイル長さが約５０〜６０ｍｍと通常のパイルよりも長いロングパイル人工芝は、その弾力特性が天然芝に近いことから、サッカーやラグビー場などの天然芝の代替材として用いられている。   A long pile artificial turf having a pile length of about 50 to 60 mm, which is longer than a normal pile, is used as a substitute for natural turf such as soccer and rugby fields because its elasticity is close to that of natural turf.

例えば特許文献１に示すように、ロングパイル人工芝によれば、パイル間に砂やゴムチップなどからなる充填材を３０〜４０ｍｍの厚みで充填し、パイルの先端を１０〜３０ｍｍ突出させることにより、天然芝に近い踏み心地や良好なボールの転がり特性などを得ることができる。   For example, as shown in Patent Document 1, according to the long pile artificial turf, by filling the piles with a filler made of sand or rubber chips with a thickness of 30 to 40 mm, and projecting the tip of the pile by 10 to 30 mm, It is possible to obtain a stepping feeling close to natural turf and good ball rolling characteristics.

最近では、ロングパイル人工芝を幼稚園などの園庭として敷設して、園児が転倒によって怪我するのを防止する目的として用いられる場合がある。しかしながら、ロングパイル人工芝を園庭として適用した場合には次のような問題があった。   Recently, long pile artificial turf is sometimes laid as a kindergarten or other kindergarten and used for the purpose of preventing children from being injured by falling. However, when long pile artificial turf is applied as a garden, there are the following problems.

すなわち、従来のロングパイル人工芝は、弾力性を得るため、充填材の一部にゴムチップが用いられているが、園庭など小規模に敷設する場合、ゴムチップが飛散して周囲が汚れるおそれがあった。また、転倒時に幼児などの口に誤って入るおそれもあった。   That is, the conventional long pile artificial turf uses rubber chips as part of the filler in order to obtain elasticity, but when laid on a small scale such as a garden, there is a risk that the rubber chips will be scattered and the surroundings will be stained. there were. There was also a risk of accidental entry into the mouth of an infant or the like when falling.

そこで、ゴムチップを充填材として用いず、砂のみを充填した場合には、次のような問題が生じる。すなわち、第１の問題は、ゴムチップを含まないため、人工芝の弾力性が著しく低下する。第２の問題は、通常はパイルが充填材の中に潜り込まないように施工するが、硬質粒状物（砂など）のみを充填した場合、砂の比重が重いため、一度に大量に充填しようとすると、パイルが充填材の中に潜り込みやすい。その結果、仕上がりが悪くなる。   Therefore, the following problem arises when only sand is filled without using a rubber chip as a filler. That is, since the first problem does not include a rubber chip, the elasticity of the artificial turf is significantly reduced. The second problem is that the piles are usually constructed so that they do not sink into the filler. However, when only hard particles (sand, etc.) are filled, the specific gravity of the sand is heavy, so an attempt is made to fill a large amount at once. Then, the pile is likely to sink into the filler. As a result, the finish is poor.

第３の問題は、パイルは経年使用に伴い、充填材との摩耗によって劣化してゆくが、硬質粒状物（砂など）のみを充填した場合、充填材が硬いため、パイルの摩耗の進行が通常よりもずっと早く進行する。   The third problem is that the pile deteriorates due to wear with the filler as it is used over time. However, when only the hard granular material (sand, etc.) is filled, the filler is hard and the pile wear progresses. Proceeds much faster than usual.

特開２００２−２４２１２０号公報JP 2002-242120 A

そこで、本発明は上述した課題を解決するため、適度な弾力性があり、施工性および耐摩耗性のよい園庭などの小規模敷設に適したロングパイル人工芝の人工芝構造体を提供することにある。   Therefore, in order to solve the above-described problems, the present invention provides an artificial turf structure of a long pile artificial turf suitable for small-scale laying such as a garden having moderate elasticity and good workability and wear resistance. There is.

上述した課題を解決するため、本発明は以下に示すいくつかの特徴を備えている。請求項１に記載の発明は、基盤上に弾性層を介して敷設された人工芝を備え、上記人工芝のパイル間に砂を主剤とする粒状物が充填されている人工芝構造体において、上記各パイルがポリエチレン製で、先端部分における断面積が０．１５〜０．３０ｍｍ２であることを特徴としている。 In order to solve the above-described problems, the present invention has several features described below. The invention according to claim 1 includes an artificial turf structure including an artificial turf laid on a base via an elastic layer, and filled with granular materials mainly composed of sand between piles of the artificial turf. Each of the piles is made of polyethylene and has a cross-sectional area of 0.15 to 0.30 mm 2 at the tip.

請求項２に記載の発明は、上記請求項１において、上記弾性層に粉砕された発泡体をバインダーにて結合した透水性を有する弾性マットが用いられることを特徴としている。   A second aspect of the present invention is characterized in that in the first aspect, an elastic mat having water permeability is used in which the foam crushed in the elastic layer is bonded with a binder.

請求項３に記載の発明は、上記請求項２において、上記発泡体として廃材のリサイクル品が用いられることを特徴としている。   The invention described in claim 3 is characterized in that, in the above-mentioned claim 2, a recycled product of waste material is used as the foam.

請求項１に記載の発明によれば、パイルの先端部分の断面積が０．１５〜０．３０ｍｍ２の範囲を満足することにより、パイルの自立性がよいため、パイルが充填材の中に潜り込みにくく、施工性がよい。 According to the invention described in claim 1, by the cross-sectional area of the distal end portion of the pile within the ranges 0.15～0.30Mm 2, since good autonomy pile, pile into the filler Difficult to sink and workability is good.

すなわち、断面積が０．１５ｍｍ２未満の場合、パイルの自立性が悪く、外観不良を生じやすい。逆に、断面積が０．３０ｍｍ２よりも大きいと、自立性はよくなる反面、パイルの風合いが硬く感じられ、使用者が転んだときに擦り傷などを生じやすくなるおそれがある。 That is, when the cross-sectional area is less than 0.15 mm 2 , the pile is not self-supporting and tends to cause poor appearance. On the other hand, if the cross-sectional area is larger than 0.30 mm 2 , the self-supporting property is improved, but the texture of the pile is felt hard, and there is a possibility that an abrasion or the like is likely to occur when the user falls.

請求項２および３に記載の発明によれば、弾性層に粉砕された発泡体をバインダーにて結合した透水性を有する弾性マットが用いられることにより、充填材が硬質粒状物のみでも十分な弾性力を得ることができる。また、廃材のリサイクル品を用いることにより、生産コストをより抑えることができる。   According to the inventions of claims 2 and 3, by using an elastic mat having water permeability in which a foam pulverized in an elastic layer is bonded with a binder, sufficient elasticity can be obtained even if the filler is only a hard granular material. You can gain power. In addition, production costs can be further reduced by using recycled waste materials.

次に本発明の実施形態について図面を参照しながら説明する。図１は本発明の一実施形態に係る人工芝構造体の要部断面図である。この人工芝構造体１は、基盤２上に形成された弾性層３の上に敷設された人工芝４を有し、人工芝４のパイル５の間には充填材６が充填されている。   Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of a main part of an artificial turf structure according to an embodiment of the present invention. The artificial turf structure 1 has an artificial turf 4 laid on an elastic layer 3 formed on a base 2, and a filler 6 is filled between piles 5 of the artificial turf 4.

基盤２は、地面を平坦に均した簡易舗装面が用いられるが、これ以外に、砂利などを敷き詰めてあってもよいし、アスファルトなどで舗装された既設舗装面を用いてもよい。本発明において、基盤２の構成は、仕様に応じて変更可能であり、任意的事項である。   As the base 2, a simple pavement surface obtained by leveling the ground is used, but other than this, gravel or the like may be spread, or an existing pavement surface paved with asphalt or the like may be used. In this invention, the structure of the base | substrate 2 can be changed according to a specification, and is an arbitrary matter.

弾性層３は、例えばスチレン，ポリエチレン，ＥＶＡなどの吸水性の低い合成樹脂の発泡体からなる弾性粒状物を接着剤や熱融着により一体成型した板体を基盤２の上に敷き並べたものからなる。   The elastic layer 3 is formed by laying on a base plate 2 a plate body in which elastic granular materials made of a synthetic resin foam having a low water absorption, such as styrene, polyethylene, and EVA, are integrally formed by adhesive or heat fusion. Consists of.

弾性粒状物は、発泡体の廃材を破砕してなるリサイクル品が用いられることが好ましい。また、その粒径は１０〜３０ｍｍであることが好ましい。すなわち、粒径が１０ｍｍ未満だと、弾性粒状物が密に詰まりすぎるため、空隙率が低下して透水性が落ちるおそれがある。逆に、３０ｍｍよりも大きいと、詰まりが粗くなりすぎ、人工芝の表面に凹凸が形成されるおそれがある。   The elastic granular material is preferably a recycled product obtained by crushing foam waste. Moreover, it is preferable that the particle size is 10-30 mm. That is, when the particle size is less than 10 mm, the elastic granular material is too densely packed, so that the porosity is lowered and water permeability may be lowered. On the contrary, if it is larger than 30 mm, the clogging becomes too rough, and there is a possibility that irregularities are formed on the surface of the artificial turf.

弾性層３の空隙率は１５〜３０％であることが好ましい。すなわち、空隙率が１５％未満の場合、十分な透水性が得られないため、水たまりなどができやすくなる。逆に、空隙率が３０％を超えると、弾性層構成材の強度が低下して、運搬中や敷設後に大きな負荷がかかると弾性層が破壊されて、凹みなどを生じるおそれがある。   The porosity of the elastic layer 3 is preferably 15 to 30%. That is, when the porosity is less than 15%, sufficient water permeability cannot be obtained, so that a puddle is easily formed. On the other hand, when the porosity exceeds 30%, the strength of the elastic layer constituting material is lowered, and when a large load is applied during transportation or after laying, the elastic layer may be destroyed, and a dent or the like may be generated.

弾性層３は、一例として層厚さＴが２０〜８０ｍｍであることが好ましい。すなわち、厚さＴが２０ｍｍ未満の場合、厚みが足りないため、弾力性が乏しくなるおそれがある。逆に、厚さＴが８０ｍｍを超えると、設置後の安定感が悪く、歩行時も不安定となる。   As an example, the elastic layer 3 preferably has a layer thickness T of 20 to 80 mm. That is, when the thickness T is less than 20 mm, the thickness is insufficient, so that the elasticity may be poor. On the other hand, when the thickness T exceeds 80 mm, the feeling of stability after installation is poor, and it becomes unstable during walking.

この例において、弾性層３は持ち運びしやすいように、あらかじめ工場などにおいて、所定大きさのマット状に形成されたものを基盤２に敷き詰めたものからなるが、弾性粒状物と接着剤とを現場にて混合し、敷設して固化させる、いわゆる現場施工によって形成してもよい。   In this example, the elastic layer 3 is formed by laying a mat 2 of a predetermined size on a base 2 in advance in a factory or the like so that it can be easily carried. It may be formed by so-called on-site construction that is mixed in, laid and solidified.

また、この例において、弾性層３は、弾性粒状物を接着剤や熱融着したものを所定の空隙率となるようにして透水性を確保しているが、弾性層３に孔あけ加工によって排水孔を所定間隔で形成するようにしてもよい。   Further, in this example, the elastic layer 3 has a water permeability by ensuring that a predetermined porosity is obtained by bonding an elastic granular material to an adhesive or heat. The drain holes may be formed at predetermined intervals.

人工芝４は、基布４１に所定間隔でパイル５が植設されている。基布４１は、例えばポリプロピレン，ポリエチレン，ナイロンなどの合成樹脂製からなる平織り布が用いられ、ポリプロピレンやポリエチレンテレフタレートなどの合成樹脂製の綿状物がパンチングにより添着されてもよい。   In the artificial turf 4, piles 5 are planted on a base cloth 41 at predetermined intervals. For the base fabric 41, for example, a plain woven fabric made of a synthetic resin such as polypropylene, polyethylene, or nylon is used, and a cotton-like material made of a synthetic resin such as polypropylene or polyethylene terephthalate may be attached by punching.

また、基布４１の裏面には、タフティングされたパイル５の抜け落ちを防止するため、ＳＢＲラテックスゴムやウレタンなどのバッキング材４２が一様に塗布されている。なお、バッキング材４２の有無は本発明において任意的事項であり、その仕様に応じて変更可能である。   Further, a backing material 42 such as SBR latex rubber or urethane is uniformly applied to the back surface of the base fabric 41 in order to prevent the tufted pile 5 from falling off. The presence or absence of the backing material 42 is an optional matter in the present invention, and can be changed according to the specifications.

パイル５は、基布４１の表面から先端までのパイル長さＨが５０〜６０ｍｍのロングパイルである。パイル５は、ポリプロピレン，ポリエチレン，ナイロンなどの合成樹脂が好適に選択されるが、本発明のように充填材が硬質充填材のみからなる場合は、耐摩耗性のよいポリエチレン、より好ましくは直鎖低密度ポリエチレンがよい。   The pile 5 is a long pile whose pile length H from the surface of the base fabric 41 to the tip is 50 to 60 mm. The pile 5 is suitably selected from synthetic resins such as polypropylene, polyethylene, and nylon. However, when the filler is made of only a hard filler as in the present invention, polyethylene having good wear resistance, more preferably linear is used. Low density polyethylene is preferred.

図２に示すように、パイル５は、モノテープヤーンまたはモノフィラメントヤーンを複数本束ねたもの、あるいは、帯状のスプリットヤーンが用いられる。パイル５がスプリットヤーンで形成されている場合、スプリットヤーンにはパイル糸５１を形成するための開繊スリットが格子配置で設けられていることが好ましい。   As shown in FIG. 2, the pile 5 is a bundle of a plurality of monotape yarns or monofilament yarns, or a strip-like split yarn. When the pile 5 is formed of a split yarn, it is preferable that the split yarn is provided with opening slits for forming the pile yarn 51 in a lattice arrangement.

ここで、モノテープヤーンとは、溶かした樹脂をフィルム状に押し出し成形したものを幅１〜２ｍｍ程度の幅の狭い短冊状に裁断したものをいい、これを８〜２０本を１束として束ねて用いられる。モノフィラメントヤーンとは、溶かした樹脂を細い口金から糸状に成形したものをいい、モノテープヤーン同様に８〜２０本を１束として束ねて用いられる。   Here, the monotape yarn refers to a product obtained by extruding a melted resin into a film shape and cutting it into a narrow strip with a width of about 1 to 2 mm. Used. The monofilament yarn refers to a melted resin formed into a thread from a thin die, and is used by bundling 8 to 20 bundles in the same manner as the monotape yarn.

スプリットヤーンとは、溶かした樹脂をフィルム状に押し出し成形したのち、幅が８〜１５ｍｍ程度の比較的幅の広い短冊状に裁断したテープに長さが１０〜２０ｍｍの細かな切れ込み（スリット）を入れたパイルをいう。スプリットヤーンは１本で基布に植設され人工芝の加工時にパイルの先端を開繊することで、先端が複数本に分かれる。   A split yarn is a thin cut (slit) with a length of 10 to 20 mm on a tape that is cut into a relatively wide strip with a width of about 8 to 15 mm after extrusion of the melted resin into a film. This is the pile you put in. One split yarn is planted on the base fabric, and when the artificial turf is processed, the tip of the pile is opened to divide the tip into a plurality of pieces.

スリットは、等長のスリットをヤーンに上下左右に平行に等幅かつ等間隔で格子に配列で形成する格子スリットと、斜め方向に等幅かつ等間隔で千鳥に配列する千鳥スリットとがある。   There are two types of slits: lattice slits that are formed by arranging equal-length slits parallel to the top, bottom, left, and right in a lattice at equal intervals and staggered slits that are arranged in a staggered manner at equal intervals and at equal intervals in an oblique direction.

図２に示すように、パイル５は、モノテープヤーンまたはモノフィラメントヤーンからなるパイル糸５１を複数本束ねたもの（この例では８〜２０本）、あるいは、スプリットヤーン（格子スリット）は先端の開繊部５１の幅が均一であるものが用いられる。なお、スプリットヤーンでも開繊スリットが千鳥配置されたものは開繊後のパイル糸５１の幅が不均一となるため、本発明には不適である。   As shown in FIG. 2, the pile 5 is a bundle of a plurality of pile yarns 51 made of monotape yarn or monofilament yarn (8 to 20 in this example), or a split yarn (lattice slit) is an open end. What has the uniform width | variety of the fine part 51 is used. It should be noted that even split yarns in which the opening slits are arranged in a staggered manner are not suitable for the present invention because the width of the pile yarn 51 after opening becomes uneven.

パイル５は、太さが１００００〜１８０００ｄｔｅｘであることが好ましい。ここでいう太さとは、モノテープヤーンまたはモノフィラメントヤーンの場合は、１束に束ねた状態の太さであり、スプリットヤーンの場合は、開繊する前の１本のヤーンの太さを言う。   The pile 5 preferably has a thickness of 10,000 to 18000 dtex. In the case of monotape yarn or monofilament yarn, the thickness referred to here is the thickness in a bundled state, and in the case of split yarn, it means the thickness of one yarn before opening.

この実施形態において、パイル５１は、モノフィラメントヤーンからなる複数本のパイル糸５１を１束ねにしたものからなり、根本側（基布４１側）から先端側に向かうにつれてパイル糸５１が分岐している。   In this embodiment, the pile 51 is made of a bundle of a plurality of pile yarns 51 made of monofilament yarns, and the pile yarns 51 are branched from the root side (base fabric 41 side) toward the tip side. .

各パイル糸５１は、その各々の先端の断面積が０．１５〜０．３０ｍｍ２であるが好ましい。すなわち、パイル糸５１の先端側の断面積が０．１５ｍｍ２未満の場合、パイルの自立性が悪く、外観不良を生じやすい。逆に、断面積が０．３０ｍｍ２よりも大きいと、自立性はよくなる反面、パイルの風合いが硬く感じられ、使用者が転んだときに擦り傷などを生じやすくなるおそれがある。 Each pile yarn 51 preferably has a cross-sectional area at the tip of each pile yarn 51 of 0.15 to 0.30 mm 2 . That is, when the cross-sectional area on the tip end side of the pile yarn 51 is less than 0.15 mm 2 , the pile is not self-supporting and tends to cause poor appearance. On the other hand, if the cross-sectional area is larger than 0.30 mm 2 , the self-supporting property is improved, but the texture of the pile is felt hard, and there is a possibility that an abrasion or the like is likely to occur when the user falls.

充填材６は珪砂などの硬質粒状物からなり、その粒径は０．２〜１．２ｍｍが好ましい。すなわち、粒径が０．２ｍｍ未満の細粒物が多く含まれると、風によって飛散したり、雨で流出するおそれがある。逆に、粒径が１．２ｍｍを超える粗粒物が多く含まれると、パイル間での収まりが悪く、転んだときに傷などを生じやすくなるおそれがある。   The filler 6 consists of hard granular materials, such as quartz sand, and the particle size has preferable 0.2-1.2 mm. That is, when a large amount of fine particles having a particle size of less than 0.2 mm is contained, there is a risk of scattering by the wind or flowing out due to rain. On the other hand, when a large amount of coarse particles having a particle size exceeding 1.2 mm is contained, the fit between the piles is poor, and there is a possibility that scratches and the like are likely to occur when the rolls.

充填材６の層厚さは、弾性層３の厚さや弾力性に応じて任意に選択されるが、充填材６の流出や飛散を防止するうえで、パイルの突出高さｈ１（充填材層の表面からパイル先端までの長さ）が１０〜３０ｍｍとなる厚さ（この実施形態では、層厚さｈ２が３０〜４０ｍｍ）であることが好ましい。   The layer thickness of the filler 6 is arbitrarily selected according to the thickness and elasticity of the elastic layer 3, but in order to prevent the filler 6 from flowing out and scattering, the pile protrusion height h1 (filler layer) The length from the surface of the pile to the tip of the pile) is preferably 10 to 30 mm (in this embodiment, the layer thickness h2 is 30 to 40 mm).

次に、本発明の具体的な実施例１，２と、その比較例について説明する。まず、下記の方法で弾性マット（弾性層）とロングパイル人工芝を作製した。
〔弾性マットの作製〕
ポリエチレン２０倍発泡体を粒径が１０〜３０ｍｍとなるように破砕し得られた弾性粒状物を熱融着によって厚さ３５ｍｍの縦１ｍ×横１ｍ（１ｍ２）の大きさのマット状に形成したのち、この弾性マットを施工現場に持ち込んで、基盤上に敷設した。なお、この弾性マットの空隙率は２５％である。
〔人工芝の作製〕
ポリエチレン製のヤーンをポリプロピレン製の平織布からなる基布にパイル長さ６０ｍｍ，パイル間隔（ゲージ）１５ｍｍで植設したのち、基布裏面にＳＢＲラテックスを一様に塗布して人工芝（縦１ｍ×横１ｍ（１ｍ２））を作製した。
〔充填材の充填〕
この各人工芝を弾性マット（弾性層）の上に敷き置いたのち、充填材をパイル間に充填した。充填材は、真比重が２．６、粒径が０．２〜１．２ｍｍのものが９０％以上を占める珪砂（硬質粒状物）を用い、厚み５ｍｍずつ計６回に分けて手作業で充填し、最終的な層厚さが３０ｍｍになるまで充填したのち、デッキブラシでパイルの先端が起きるようにブラシ掛けを３０分間行った。しかる後、上記方法にて作製した人工芝を以下の方法で評価した。 Next, specific examples 1 and 2 of the present invention and comparative examples thereof will be described. First, an elastic mat (elastic layer) and a long pile artificial turf were prepared by the following method.
[Production of elastic mat]
An elastic granular material obtained by crushing a polyethylene 20-fold foam so as to have a particle size of 10 to 30 mm is formed into a mat having a size of 1 m in length and 1 m in width (1 m 2 ) having a thickness of 35 mm. After that, this elastic mat was brought to the construction site and laid on the base. The porosity of this elastic mat is 25%.
[Production of artificial grass]
A polyethylene yarn was planted on a base fabric made of a plain woven fabric made of polypropylene with a pile length of 60 mm and a pile interval (gauge) of 15 mm. 1 m × 1 m (1 m 2 )) was produced.
[Filling material]
Each artificial grass was laid on an elastic mat (elastic layer), and then a filler was filled between the piles. The filler used is silica sand (hard granular material) with a true specific gravity of 2.6 and a particle size of 0.2-1.2 mm occupying 90% or more. After filling and filling until the final layer thickness was 30 mm, brushing was performed for 30 minutes so that the tip of the pile occurred with a deck brush. Thereafter, the artificial turf prepared by the above method was evaluated by the following method.

〔仕上がり確認〕
実施例１，２および比較例の人工芝の敷設後、全体の仕上がりを目視にて確認した。さらには、その人工芝の表面に突出しているパイル糸をランダムに３カ所選んで、各パイル糸の先端の幅を１０回計測し、パイルの平均幅と平均断面積を測定した。
〔摩耗状態確認〕
敷設した人工芝を１年間放置し、その上を歩行して、人工芝の摩耗状態を観察した。 [Finish confirmation]
After laying the artificial turf of Examples 1 and 2 and the comparative example, the overall finish was visually confirmed. Further, three pile yarns protruding at the surface of the artificial turf were selected at random, the width of the tip of each pile yarn was measured 10 times, and the average width and average cross-sectional area of the pile were measured.
