本考案は人工芝の改良に関する。 The present invention relates to improvement of artificial turf.

【0002】[0002]

【従来の技術及びその技術的課題】[Prior art and its technical problem]

テニスコート、ゴルフ場の歩径路、ゲートボール場、グラウンドなどにおいて 人工芝が汎用されている。こうした人工芝はプラスチックシートにプラスチック 製の芝部材を所定間隔で配した構造からなっており、芝部材が突起状ないし針状 の剛質のものでは実際の芝の性状と大きな相違があることから、繊維糸状ないし 極細短冊状の軟質な芝部材を植え立てたものが使用されている。しかし芝部材の 植え立て間隔には限度があり、また芝部材が柔軟で腰が乏しいため、踏み締めに より芝部材が斜めになってシート面が部分的に露出して芝機能を発揮できなくな りやすいという問題があった。 Artificial turf is widely used in tennis courts, golf course paths, gateball fields, and the ground. Such artificial turf has a structure in which plastic turf members are arranged at a predetermined interval on a plastic sheet, and if the turf member is a projecting or needle-shaped rigid turf member, there is a big difference from the actual turf properties. A soft grass member in the form of fiber thread or ultra-thin strip is planted and used. However, there is a limit to the planting interval of the turf members, and because the turf members are flexible and lacking in rigidity, the turf members become slanted by trampling and the seat surface is partially exposed so that the turf function cannot be exerted. There was a problem that it was easy to get.

【0003】 この対策として、従来、芝部材の間に砂を充填したものが提案されているが、 この構造では当初は砂が流動性があり、踏み締め感が良好であるものの、砂がそ れ自体の重量や雨水の通過による粒子の移動で沈下して隙間が埋められ、また使 用者の荷重や雪による静圧が加わるため、時間の経過とともに密度が高くなって あたかもコンクリートのように硬くなってしまい、歩行時や、疾走時に滑ったり 、衝撃で疲労の増加を招いたり、競技用球の弾みにイレギュラーを生じさせたり するなど人工芝本来の特性を発揮できなくなるという問題があった。As a countermeasure against this, there has been conventionally proposed a method in which sand is filled between turf members, but in this structure, the sand is fluid at first, and the feeling of trampling is good, but the sand is deteriorated. It sinks due to its own weight and the movement of particles due to the passage of rainwater to fill the gaps, and the static pressure due to the user's load and snow is applied, so the density becomes high over time and it becomes as hard as concrete. There was a problem that the original characteristics of artificial turf could not be exhibited, such as slipping during walking or sprinting, increased fatigue due to impact, and irregularity in the bounce of the competition ball. .

【0004】 本考案は前記のような目的を達成するために考案されたもので、その目的とす るところは、簡単な構造により長期間経過しても硬くならない実用的な砂入り人 工芝を提供することにある。The present invention was devised in order to achieve the above-mentioned object, and its purpose is to provide a practical sand-filled man-made grass that does not become hard even after a long period of time due to its simple structure. To provide.

【課題を解決するための手段】[Means for Solving the Problems]

上記目的を達成するため本考案は、シート状基板面上に芝部材を植設した人工 芝において、前記芝部材間にゴム質などからなる弾性粉粒状物を層状に充填し、 この弾性粉粒状物層上に砂などの無機質粉粒状物を層状に配したものである。 In order to achieve the above object, the present invention is an artificial turf in which a turf member is planted on the surface of a sheet-like substrate, and elastic fluff particles made of rubber or the like are filled in layers between the turf members. Inorganic powder particles such as sand are arranged in layers on the product layer.

【実施例】【Example】

以下本考案の実施例を添付図面に基いて説明する。 図1と図2は本考案による人工芝の一実施例を示しており、Aは基床、Bは基 床Aに敷設された人工芝本体である。前記基床Aは、好ましくは透水性組織例え ば粗骨材をセメントまたは合成樹脂接着剤をバインダとして結合した透水性コン クリートや、粗骨材をアスファルトに混合した透水性アスファルトなどからなっ ている。 前記人工芝本体Bは、耐熱、耐水、耐侯性の良好なプラスチックからなるシー ト状基板1に軟質な芝部材2を所定間隔で無数に植え立てており、芝部材2はた とえば耐熱性と耐摩耗性の良好なプラスチック製の極細短冊状片の束2aを長さ 方向中間部でヘアピン状に屈折し、その屈折部位2bをシート状基板1にウエル ダーなどにより定着している。シート状基板1は透水穴10が配設されている。 An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 and 2 show an embodiment of an artificial turf according to the present invention, where A is a base floor and B is an artificial turf body laid on the base floor A. The base bed A is preferably made of a water-permeable structure, for example, a water-permeable concrete obtained by combining coarse aggregate with cement or a synthetic resin adhesive as a binder, or a water-permeable asphalt obtained by mixing coarse aggregate with asphalt. . The artificial turf body B is composed of a sheet-like substrate 1 made of plastic having good heat resistance, water resistance and weather resistance, and an infinite number of soft turf members 2 planted at predetermined intervals. A bundle 2a of plastic thin strips having good abrasion resistance is refracted in a hairpin shape at an intermediate portion in the longitudinal direction, and the refraction portion 2b is fixed to the sheet substrate 1 by a welder or the like. The sheet-like substrate 1 is provided with water-permeable holes 10.

【0007】 本考案においては、前記人工芝本体Bの各芝部材2の空隙に、シート状基板1 の上面を底として弾性粉粒状物3を層状に充填し、この弾性粉粒状物層の上に砂 などの無機質粉粒状物4を層状に配している。 弾性粉粒状物3は、合成または天然のゴムを粉砕したゴムチップ、発泡スチロ ール、発泡ポリスチレン、発泡ポリオリフィンで代表される合成樹脂系の粉砕物 、コルクで代表される木質系の粉砕物の一種または2種以上の混合物である。 弾性粉粒状物3の粒径は軟質芝部材2の配設間隔より小さく、平均粒径で3mm 以下一般に0.7〜2mm程度が好ましい。弾性粉粒状物3は層全体が一様な粒 径であることは要さず、粒径の異なる複数の層からなっていてもよい。また、そ の場合各層が材質を異にしていてもよい。In the present invention, the voids of each turf member 2 of the artificial turf body B are filled with the elastic powdery granules 3 in layers with the upper surface of the sheet-like substrate 1 as the bottom, and the elastic powdery granules layer is topped. Inorganic powder particles 4 such as sand are arranged in layers. The elastic powder granules 3 are a kind of a synthetic resin-based crushed product represented by rubber chips obtained by crushing synthetic or natural rubber, styrofoam, expanded polystyrene, expanded polyorifin, and a wood-based crushed product represented by cork. Alternatively, it is a mixture of two or more kinds. The particle size of the elastic powder particles 3 is smaller than the disposition interval of the soft grass member 2, and the average particle size is preferably 3 mm or less and generally about 0.7 to 2 mm. The elastic powdery granular material 3 does not need to have a uniform particle size throughout the layer, and may be composed of a plurality of layers having different particle sizes. In that case, the materials of the layers may be different.

【0008】 無機質粉粒状物4は弾性粉粒状物3を安定して押えることができるように弾性 粉粒状物3よりも比重の大きなものたとえばけい砂が使用され、粒径は弾性粉粒 状物3と同程度以下たとえば平均粒径で0.5〜1.5mm程度がのものが好ま しい。無機質粉粒状物4は一層であってもよいし粒径の異なる複数の層としても よい。 無機質粉粒状物4は芝部材2の先端が適度に露出し、疾走などによりスパイク を踏み込んでも弾性粉粒状物3をえぐりだしたりせず、弾性粉粒状物3の良好な クッション性を保持しうる層厚さ、たとえば弾性粉粒状物層と無機質粉粒状物層 の比を1:1〜1:4とすることが好ましい。 なお、場合によっては弾性粉粒状物3に濃度の薄い接着剤を塗布して弾性粉粒 状物3同士を点状に結合させるようにしてもよく、これは弾性粉粒状物3を充填 した後でも行うことができる。As the inorganic powder granules 4, a material having a larger specific gravity than the elastic powder granules 3 such as silica sand is used so that the elastic powder granules 3 can be pressed stably, and the particle size is the elastic powder granules. 3 or less, for example, an average particle size of 0.5 to 1.5 mm is preferable. The inorganic powder / granular material 4 may be a single layer or a plurality of layers having different particle sizes. The tip of the turf member 2 of the inorganic powder granules 4 is appropriately exposed, and the elastic powder granules 3 will not be dug out even when a spike is stepped on by running or the like, and the good cushioning property of the elastic powder granules 3 can be maintained. It is preferable that the layer thickness, for example, the ratio of the elastic powder / granular material layer to the inorganic powder / granular material layer is 1: 1 to 1: 4. In some cases, an adhesive having a low concentration may be applied to the elastic powdery granules 3 so that the elastic powdery granules 3 are bonded to each other in a dot shape. But you can do it too.

【実施例の作用】[Operation of the embodiment]

本考案は前記のような構成からなるので、芝部材2は柔軟で腰が弱くても、各 芝部材2間の根部領域に弾性粉粒状物3が充填され、その上に無機質粉粒状物4 が層状に充填されているため踏まれても倒れが生じず良好な直立性を維持するこ とができ、しかも踏み面が無機質粉粒状物4であるため、スパイクなどの引掛か りがよい上に、無機質粉粒状物4が下層の弾性粉粒状物3で支えられているため 全体として良好なクッション性があり、踏み締め感やボールの弾みなどが自然の 芝に近いものとなる。 さらに、無機質粉粒状物4が下層の弾性粉粒状物3に支えられているため、踏 み締められたり、雪による静圧がかかったりしても、弾性粉粒状物3による弾力 性で無機質粉粒状物4の高密度化が防止され、また無機質粉粒状物4の下層が沈 降して弾性粉粒状物3の粒子間空隙を埋めても、弾性粉粒状物3の弾性でほぐさ れて動かされる。従って、時間が経過しても無機質粉粒状物4が硬くなるような ことがなく、良好な性状を維持することができる。また上層の無機質粉粒状物4 で上から押えられているため、比重の軽いバラ状の弾性粉粒状物3が浮上して風 で飛んだりすることなく安定した層状態を維持することができ、弾性粉粒状物3 は粒子相互間に隙間を有しているため雨水の浸透性もよく、シート状基板1の透 水穴10から基床Aに流すことができる。 また、基床と人工芝本体Bとの間にクッション層を設ける必要がなく、基床に 直に人工芝本体Bを敷設することができるため、施工も簡単容易で安価なものと することができる。 Since the present invention is configured as described above, even if the grass member 2 is flexible and has a weak stiffness, the elastic powder granules 3 are filled in the root region between the grass members 2 and the inorganic powder granules 4 are formed thereon. Since it is filled in layers, it does not fall down even if it is stepped on, and it is possible to maintain good uprightness. Moreover, since the tread surface is the inorganic powder granules 4, it is easy to catch spikes and the like. In addition, since the inorganic powder granules 4 are supported by the elastic powder granules 3 in the lower layer, the cushioning property as a whole is good, and the feeling of trampling and the bouncing of the ball are close to those of natural grass. Further, since the inorganic powder particles 4 are supported by the elastic powder particles 3 in the lower layer, the elasticity of the inorganic powder particles 3 causes the inorganic powder particles to be elastic even when they are stepped on or static pressure is applied by snow. The densification of the granules 4 is prevented, and even if the lower layer of the inorganic powder granules 4 sinks and fills the inter-particle voids of the elastic powder granules 3, the elasticity of the elastic powder granules 3 loosens and moves. Be done. Therefore, the inorganic powdery or granular material 4 does not become hard over time, and good properties can be maintained. Further, since the upper layer of inorganic powder particles 4 is pressed from above, the loose elastic powder particles 3 having a low specific gravity do not float up and are not blown by the wind, and a stable layer state can be maintained. Since the elastic granular material 3 has gaps between the particles, it has good permeability of rainwater, and can flow from the water permeable holes 10 of the sheet-shaped substrate 1 to the base floor A. Further, since it is not necessary to provide a cushion layer between the base floor and the artificial turf body B, and the artificial turf body B can be laid directly on the base floor, the construction can be made easy and easy and inexpensive. it can.

【考案の効果】[Effect of device]

以上説明した本考案によるときには、シート状基板面上に芝部材を植設した人 工芝において、前記芝部材間にゴム質などからなる弾性粉粒状物を層状に充填し 、この弾性粉粒状物層上に砂などの無機質粉粒状物を層状に配したので、弾性粉 粒状物層の良好なクッション性と通水性とにより無機質粉粒状物の密度上昇によ る硬化を防止し、長期に渡り自然に近い良好な芝性能を発揮させることができ、 また、無機質粉粒状物により弾性粉粒状物層を上から押えるため、弾性粉粒状物 層が散逸することなく安定した層状態を保持させることができ、しかも構造が簡 単で施工を容易かつ安価に行うことができるなどすぐれた効果が得られる。 According to the present invention described above, in an artificial turf in which a grass member is planted on the surface of a sheet-like substrate, elastic powder granules made of rubber or the like are layered between the grass members, and the elastic powder granules are filled. Since the inorganic powder granules such as sand are arranged in layers on the layer, the good cushioning property and water permeability of the elastic powder granule layer prevent the inorganic powder granules from hardening due to the increase in density, and can be used for a long period of time. It is possible to exhibit good turf performance close to nature, and because the elastic powder / granular material layer is pressed from above by the inorganic powder / granular material, the elastic powder / granular material layer does not disperse and maintains a stable layer state. In addition, the structure is simple, and the construction is easy and inexpensive, which is an excellent effect.
