Description
本考案は、再生可能資源を有効利用し、軽量で作業性に優れた側溝用の蓋に関するものである。 The present invention relates to a gutter lid that makes effective use of renewable resources, is lightweight, and has excellent workability.
車両走行道路等に付属している側溝には、コンクリート製の蓋、もしくはグレーチングと呼ばれる鋼材を格子状に組んだ溝蓋が設置されている。従来、側溝の蓋は、トラックのクレーン吊り具を使用して、本体を上げたり下げたりして、所要の作業をしているが、重くて取り扱いにくいので作業性が悪く、自動車等の輪荷重に対応して滑り、騒音、がたつき等の問題点があった。これらの蓋は、車両の通行に対して十分な強度がある反面、その重量が非常に重く、設置や修復の際に作業性が悪い。また、グレーチングの場合は、金属のため高価であるばかりでなく、盗難に遭いやすく、グレーチング同士を連結させるなどの対策が取られており、作業性の低下を招いている。 In a side groove attached to a vehicle traveling road or the like, a concrete lid or a groove lid made of a steel material called grating is assembled in a lattice shape. Conventionally, the side gutter lid has been used to perform the required work by lifting and lowering the main body using truck crane lifting equipment, but it is heavy and difficult to handle, so it is poor in workability and wheel load of automobiles etc. There were problems such as slip, noise, and rattling. These lids have sufficient strength against vehicle traffic, but they are very heavy and have poor workability during installation and repair. Further, in the case of grating, not only is it expensive because it is metal, but it is easy to be stolen and measures such as connecting the gratings to each other are taken, resulting in a decrease in workability.
上記のような作業性の悪さを改善するためにプラスチック製の溝蓋が開発されている。しかし、プラスチックの比重は軽く水に浮いてしまうため、金属性の補強筋入れたり（特許文献１）、コンクリートや砂利などの重量物を載せたり（特許文献３）、骨材を混和する（特許文献３）などの方法で重くする対策が取られている。しかし、このような方法は、プラスチックの最大の特徴である溶融成形性を低下もしくは不可能にしてしまうという問題点があった。 In order to improve the poor workability as described above, a plastic groove lid has been developed. However, since the specific gravity of plastic is lightly floating in water, metal reinforcing bars are inserted (Patent Document 1), heavy objects such as concrete and gravel are placed (Patent Document 3), and aggregates are mixed (patent) Measures to make it heavier by methods such as literature 3) are taken. However, such a method has a problem that the melt moldability, which is the greatest characteristic of plastic, is reduced or impossible.
本考案が解決しようとする課題は、コンクリート製および金属製側溝蓋の重量とグレーチングの盗難対策に伴う作業性の問題点と、それを改善するために開発されたプラスチック製の側溝蓋の成形性の低さに関する問題点である。 The problems to be solved by the present invention are the problems of workability associated with the weight of concrete and metal side gutter lids and anti-theft measures of grating, and the moldability of plastic side gutter lids developed to improve it. This is a problem related to the lowness of.
本考案は、再生可能資源である竹由来の微細な短繊維を含む粉末をプラスチックに混和することで、プラスチックの溶融成形性を維持したまま、比重を増大させて水に浮かないようにし、さらに機械的強度を高めることを特徴とする。 The present invention incorporates powder containing fine short fibers derived from bamboo, which is a renewable resource, into plastic, thereby increasing the specific gravity while maintaining the melt moldability of the plastic so that it does not float on water. It is characterized by increasing mechanical strength.
水蒸気処理後に粉砕して得られる１０００μｍ以下の微細な竹繊維の引張強度は、約４０MPa以上であり、さらにそのみかけ比重は約1.３である。したがって、この竹繊維を含む竹粉をプラスチックに対して、１０：９０から８０：２０の重量比でブレンドすることにより、プラスチックの機械的強度と比重増大に寄与する。 The fine bamboo fiber of 1000 μm or less obtained by pulverization after the steam treatment has a tensile strength of about 40 MPa or more and an apparent specific gravity of about 1.3. Therefore, by blending bamboo powder containing this bamboo fiber with a weight ratio of 10:90 to 80:20 with respect to the plastic, it contributes to an increase in the mechanical strength and specific gravity of the plastic.
本考案で用いるプラスチックとしては、家電リサイクル法、自動車リサイクル法、容器包装リサイクル法などの法律に基づき回収分別されたプラスチック類が好適に用いられる。具体的には、ポリプロピレン主体成分、ＡＢＳ樹脂やＡＳ樹脂などのスチレン系プラスチック成分、およびポリエチレンテレフタレート（ＰＥＴ）系樹脂などの熱溶融性樹脂である。さらに、コンパクトディスクなどに用いられるポリカーボネート系樹脂も好ましく用いられる。 As the plastic used in the present invention, plastics collected and sorted based on laws such as the Home Appliance Recycling Law, the Automobile Recycling Law, and the Containers and Packaging Recycling Law are preferably used. Specifically, a polypropylene main component, a styrene plastic component such as ABS resin or AS resin, and a heat-meltable resin such as polyethylene terephthalate (PET) resin. Further, a polycarbonate-based resin used for a compact disk or the like is also preferably used.
本考案の側溝蓋は、コンクリート製や金属製に比べて軽量であるため、作業性に富み、溶融成形可能であるため、複雑な形状や表面の滑り止め用模様の付与も容易である。 Since the gutter lid of the present invention is lighter than concrete or metal, it has excellent workability and can be melt-molded. Therefore, it is easy to provide a complicated shape and a non-slip pattern on the surface.
本考案の側溝蓋は、再生可能資源である竹粉を含有しているため、製造に伴う炭酸ガス発生抑制に寄与する。さらに、プラスチックとして、回収分別品をリサイクルすることができ、さらなる炭酸ガス発生抑制に寄与する。 Since the gutter lid of the present invention contains bamboo powder, which is a renewable resource, it contributes to the suppression of carbon dioxide generation associated with production. Furthermore, as a plastic, the collected and separated product can be recycled, which contributes to further suppression of carbon dioxide generation.
本考案に付与された排水用の円形孔は、その直径が５〜５０ｍｍであるため、子供の靴が嵌る危険性はなく、また、その総面積が蓋上面積の１〜３０％、好ましくは３〜２０％を占めるため、効果的な排水が可能である。さらに、下方に向かって拡大するテーパー状となっているため、孔内部で閉塞状態となることがない。なお、この円形孔は、真円である必要はなく、溶融成形性に応じて楕円体であることも好適に選択可能である。 Since the circular hole for drainage given to the present invention has a diameter of 5 to 50 mm, there is no risk of fitting a child's shoes, and the total area is 1 to 30% of the area on the lid, preferably Since it accounts for 3 to 20%, effective drainage is possible. Furthermore, since it has a tapered shape that expands downward, it does not become a closed state inside the hole. Note that the circular hole does not need to be a perfect circle, and can be suitably selected to be an ellipsoid according to melt moldability.
本考案に付与された滑り止め用の模様は、滑り止めの機能を有するものであれば特に限定されないが、好適には、粗面模様、線状模様、円形模様、多角形模様などが単独もしくは組み合わされて、本考案の側溝蓋の上表面上に凹凸模様として付与される。 The anti-slip pattern imparted to the present invention is not particularly limited as long as it has an anti-slip function, but preferably a rough surface pattern, a linear pattern, a circular pattern, a polygonal pattern, etc. are used alone or In combination, it is given as a concavo-convex pattern on the upper surface of the gutter lid of the present invention.
本考案の側溝蓋は、外周の所定位置を欠いて掛部としているため、設置および修復時に作業性が容易である。 Since the side groove cover of the present invention has a predetermined portion on the outer periphery as a hanging portion, workability is easy during installation and repair.
良好な設置および修復の作業性、成形性、および排水性を再生可能資源である竹粉をプラスチックとブレンドし、溶融成形することによって実現した。 Good installation and restoration workability, formability, and drainage were realized by blending bamboo powder, a renewable resource, with plastic and melt molding.
