Description
本考案は、排水性と滑り止め性を兼備した、溝蓋用グレーチング材に関する。
特に、食品製造工場のような水を多量に扱う場所において、排水性と滑り止め性を兼ね備えた溝蓋用グレーチング材に関する。The present invention relates to a grating material for a groove lid, which has both drainage and non-slip properties.
In particular, the present invention relates to a grating material for a groove lid having both drainage and non-slip properties in a place such as a food manufacturing factory where a large amount of water is handled.
従来から、排水溝の溝蓋として、金属製の溝蓋用グレーチング材が使用されている。これらの溝蓋用グレーチング材は、歩行者の落下防止から、頑丈な金属製格子状のグレーチング材が使用されるのが一般的である。
しかし、食品製造工場の内部のように、洗浄用の水を多量に扱う場所では、従来の溝蓋用グレーチング材が金属製であるために、作業者がこの溝蓋用グレーチング材上で足を滑らせて転倒する事故が多発し、安全上の課題があった。
溝蓋用グレーチング材の滑り止め改良を目的に、例えば、金属製格子の上面に凹凸を設けたり（特許文献１）、この金属製格子の一部に穴開き突起付きの被覆材を取り付ける方法（特許文献２）が提案されている。
他方、溝蓋用として、特別の形状としたステンレス板を用いることで、多量の水を使用する調理場等の水回りの衛生面と滑り止めを改善する提案（特許文献３）がされている。Conventionally, a metal grating material for a groove lid has been used as a groove lid of a drainage groove. As these grating materials for groove lids, a sturdy metal grid-like grating material is generally used to prevent pedestrians from falling.
However, in places where a large amount of cleaning water is handled, such as inside a food manufacturing factory, since the conventional grating material for the groove lid is made of metal, the operator puts his foot on the grating material for the groove lid. There were many accidents of slipping and falling, and there was a safety issue.
For the purpose of improving the anti-slip of the grating material for the groove lid, for example, a method of providing unevenness on the upper surface of the metal lattice (Patent Document 1) or attaching a covering material with a perforated protrusion to a part of the metal lattice (Patent Document 1). Patent Document 2) has been proposed.
On the other hand, it has been proposed to improve the hygiene and non-slip properties around water in kitchens and the like where a large amount of water is used by using a specially shaped stainless steel plate for the groove lid (Patent Document 3). ..
特許文献１に示すような、金属製格子上面に凹凸を設けたとしても、水を多量に扱う場所の溝蓋用グレーチング材としては、滑りを防ぐことが困難であった。
また、特許文献２に示すような、金属製格子上面に穴開き突起付きの被覆材を溝蓋用グレーチング材の上面に取り付けることで、滑り止めの効果はあるものの、格子全面にこのような穴開き突起付き被覆材を取り付けるには、手間や費用が多大となり、実用化が困難であった。
更に、特許文献３に示すような、溝蓋用グレーチング材として、排水孔と特定の垂れ部を設けることで、排水性は改善されるものの、滑り止め効果が乏しいものであった。
本考案の目的は、従来技術の欠点を改良し、食品製造工場のような水を多量に扱う場所において、排水性と滑り止め性を兼ね備えた溝蓋用グレーチング材を提供することである。Even if the upper surface of the metal lattice is provided with irregularities as shown in
Further, as shown in Patent Document 2, by attaching a covering material having a perforated protrusion on the upper surface of the metal lattice to the upper surface of the grating material for the groove lid, although the anti-slip effect is obtained, such a hole is formed on the entire surface of the lattice. It was difficult to put it into practical use because it took a lot of time and cost to attach the covering material with the opening protrusion.
Further, as shown in Patent Document 3, by providing a drainage hole and a specific hanging portion as the grating material for the groove lid, the drainage property is improved, but the anti-slip effect is poor.
An object of the present invention is to improve the drawbacks of the prior art and to provide a grating material for a groove lid having both drainage and non-slip properties in a place where a large amount of water is handled such as a food manufacturing factory.

Become.
In addition, a reliable anti-slip effect can be obtained by the perforated protrusions arranged on the upper surface of the steel sheet in a special arrangement.
以下、本考案の詳細について、図面を用いて説明するが、本考案はこの図面に限定されるものではない。
本考案は、第１図に示すように鋼板上面に矩形に穿孔された複数の長孔状通水部と穴開き突起部が配設されている。
複数の長孔状通水部は、食品製造工場のような水を多量に扱う場所に設置された溝蓋用グレーチング材において、水を排水溝へ排水する機能を有する。
長孔状通水部の形状は、排水性と溝蓋用グレーチング材製造時の加工性から、矩形に穿孔されている。
矩形の大きさは特に限定されるものではなく、使用される場所や排水量によって設計可能である。
本考案に使用する鋼板の材質や厚みは、特に限定されないが、耐久性や穴開き突起部の加工性から、材質としてステンレス鋼板が望ましい。ステンレス鋼板の材質としては、ＳＵＳ４４３Ｊ１等が更に好ましい。
鋼板の厚みは、通常３ｍｍ〜４ｍｍが採用されるが、加工性から１ｍｍ〜１．５ｍｍであることが更に好ましい。
本考案の溝蓋用グレーチング材には、鋼板の荷重に対する耐久性を高める目的で、必要に応じて、溝蓋用グレーチング材の裏面にリブ材等の補強材を設けてもよい。Hereinafter, the details of the present invention will be described with reference to the drawings, but the present invention is not limited to this drawing.
In the present invention, as shown in FIG. 1, a plurality of elongated hole-shaped water passage portions and perforated protrusions are arranged on the upper surface of the steel plate in a rectangular shape.
The plurality of elongated pore-shaped water passage portions have a function of draining water to a drainage ditch in a grating material for a groove lid installed in a place such as a food manufacturing factory where a large amount of water is handled.
The shape of the elongated water passage portion is perforated in a rectangular shape due to the drainage property and the workability at the time of manufacturing the grating material for the groove lid.
The size of the rectangle is not particularly limited and can be designed according to the place of use and the amount of drainage.
The material and thickness of the steel sheet used in the present invention are not particularly limited, but a stainless steel sheet is desirable as the material from the viewpoint of durability and workability of the perforated protrusions. As the material of the stainless steel plate, SUS443J1 or the like is more preferable.
The thickness of the steel sheet is usually 3 mm to 4 mm, but it is more preferably 1 mm to 1.5 mm from the viewpoint of workability.
The groove lid grating material of the present invention may be provided with a reinforcing material such as a rib material on the back surface of the groove lid grating material, if necessary, for the purpose of increasing the durability of the steel plate against a load.
第２図は、本考案の鋼板上面に配設する、矩形に穿孔された複数の長孔状通水部と穴開き突起部の配置を示す。
第２図に示すように、本考案の溝蓋用グレーチング材では、鋼板上面の全面に複数の長孔状通水部と穴開き突起部が交互に配設されている。
本考案では、第２図に示す長孔状通水部の開口面積ｓの合計（Ｓ２）が、溝蓋用グレーチング材全体の面積（Ｓ１）に対する割合（Ｓ２／Ｓ１ ×１００）が、１０％〜４０％であることが望ましい。
開口面積の合計の割合が４０％以上では、通水性は増すものの溝蓋用グレーチング材の強度が低下し、凹み等により耐久性が劣るものとなる。
１０％以下では、通水性が低下し、本考案の目的が十分に達成できなくなる恐れがある。
好ましい割合は、１５％〜３０％である。FIG. 2 shows the arrangement of a plurality of rectangular perforated water passage portions and perforated protrusions arranged on the upper surface of the steel plate of the present invention.
As shown in FIG. 2, in the grating material for a groove lid of the present invention, a plurality of elongated hole-shaped water passage portions and perforated protrusions are alternately arranged on the entire surface of the upper surface of the steel plate.
In the present invention, the ratio (S2 / S1 × 100) of the total opening area s (S2) of the elongated water passage portion shown in FIG. 2 to the total area (S1) of the groove lid grating material is 10%. It is desirable that it is ~ 40%.
When the total ratio of the opening areas is 40% or more, the water permeability is increased, but the strength of the groove lid grating material is lowered, and the durability is deteriorated due to dents and the like.
If it is 10% or less, the water permeability is lowered, and the object of the present invention may not be sufficiently achieved.
The preferred ratio is 15% to 30%.
第３図は、第２図に示す複数の長孔状通水部と穴開き突起部の位置関係を説明するための一部拡大図である。
本考案においては、穴開き突起部の位置が６角形の各頂点部にあたる位置に配設されることが重要である。
第３図中の破線は、穴開き突起部の相互の配置を理解するための補助線である。
穴開き突起部の位置を６角形の各頂点部にあたる位置に配設することにより、溝蓋用グレーチング上方を歩行する作業者が、どの方角から歩行しても、十分な滑り止め効果を発揮することが可能となる。
本考案では、上記穴開き突起部の配置に加えて、穴開き突起部が、６角形の中心点にあたる位置に配設されていることが、更に好ましい。
６角形の中心点にあたる位置に配設されていることにより、滑り止め効果が一層有効に発揮される。FIG. 3 is a partially enlarged view for explaining the positional relationship between the plurality of elongated water passage portions and the perforated protrusions shown in FIG. 2.
In the present invention, it is important that the position of the perforated protrusion is arranged at a position corresponding to each apex of the hexagon.
The broken line in FIG. 3 is an auxiliary line for understanding the mutual arrangement of the perforated protrusions.
By arranging the position of the perforated protrusion at the position corresponding to each apex of the hexagon, a worker walking above the grating for the groove lid exhibits a sufficient anti-slip effect regardless of the direction of walking. It becomes possible.
In the present invention, in addition to the arrangement of the perforated protrusions, it is more preferable that the perforated protrusions are arranged at positions corresponding to the center points of the hexagon.
By arranging the hexagon at a position corresponding to the center point, the anti-slip effect is more effectively exhibited.
第４図は、本考案の穴開き突起部の形状の一例を示す拡大図である。
第４図中の（ａ）は穴開き突起部の形状であり、形状は円形でも楕円形や三角形であってもよい。
第４図中の（ｂ）は、穴開き突起部の断面形状を示す。FIG. 4 is an enlarged view showing an example of the shape of the perforated protrusion of the present invention.
FIG. 4A is the shape of the perforated protrusion, and the shape may be circular, elliptical, or triangular.
FIG. 4B in FIG. 4 shows the cross-sectional shape of the perforated protrusion.
本考案の溝蓋用グレーチング材は、食品工場のような水を多量に扱う場所に用いて性能が発揮されるが、これらに限定されるものではなく、通常のグレーチング材の上面に重ねて使用することで、優れた排水性と滑り止め効果を発揮することが可能である。 The grating material for a groove lid of the present invention exhibits its performance when used in a place where a large amount of water is handled, such as a food factory, but is not limited to these, and is used by superimposing it on the upper surface of a normal grating material. By doing so, it is possible to exhibit excellent drainage and anti-slip effect.
