【発明の属する技術分野】
本発明は、滑り低減溝蓋に関するものである。
【０００２】
【従来の技術】
従来、溝蓋は、道路の側溝用として道路と平行に設けられたり、あるいは、道路の横断溝用として道路を横切るように設けられた溝にそれぞれ敷設されており、これら溝蓋であっても、長スパン用と称される幅広の溝蓋である場合もあり、この溝蓋上を車両が通行すると、素材が金属製のため、雨天等では滑る場合があり、交通事故となる恐れがあった。
【０００３】
そのため、近年では溝蓋用構造材には、パネル（表面）に滑り低減突起を取り付けて滑りを防止する手段が施されているが、その経験では、溝蓋用構造材に対して直角方向に作用する滑り低減効果の方が、平行方向より高いことが認められ、実公平５−１９４２５号公報に記載されている。
【０００４】
【発明が解決しようとする課題】
そこでこの発明は、これらの各欠点を除去するために、幅広の溝蓋において滑りを低減するよう発明されたものであり、長スパン（幅広）用オープンタイプ溝蓋の補助部材を、横部材ピッチ間で斜め（対角線状）になるように構成し、あるいは、溝蓋の主部材間において、左・右交互に傾斜するように構成した補助部材を追加した溝蓋より構成されるものである。
【０００５】
【課題を解決するための手段】
以上のような課題を解決するために、この発明は、幅広の溝蓋において、車両のタイヤの進行方向に対して、補助部材を平行方向にならないように配置したものであり、補助部材を斜めに配置する斜方向補助部材を設けた滑り低減溝蓋を開発するものである。

【００１４】
【発明の効果】
この発明によると、幅広の溝蓋において、溝蓋表面の滑り低減の効果を、溝蓋の突起形状のみに頼るものではなく、別個の斜方向補助部材を取りつけることにより、如何なる車両の進行方向のタイヤに対しても滑り低減効果の向上が図れる。
【００１５】
さらに、補助部材及び斜方向補助部在の上面に設けた滑り低減突起が、上面に所定間隔に設けられ、かつ滑り低減突起の形状が、全体として平面視で型鋼長手方向に対して互いに逆向きで斜交したものであることにより、滑り低減性能を向上させる等の極めて有益なる効果を奏するものである。
