NON-SLIP TREAD PLATE, STEPPING BASE, STACKING BOARD FOR TEMPORARY SCAFFOLDING BOARD, AND TREAD BOARD MANUFACTURING DEVICE
To provide a tread plate which is not slippery when a worker walks or works even if oil components or dust components adhere to a work floor or a drainage ditch lid.SOLUTION: In a non-slip tread plate 1 made of a stainless steel plate having punched holes 10 arranged in a plurality of rows, an upright portion 11 around the punched holes 10 is sharply cut to make it easier to bite into a sole. Specifically, a width of the upright portion 11 is 1.5 mm, and the top of the upright portion 11 is provided with a pointed head 18 having a notch. Further, the outer surface side of the upright portion 11 is made to have a pointed head having an inclination angle sharper than 45 degrees with respect to the surface of the non-slip tread plate 1. In addition, an opening ratio of the punched hole 10 is set to be 7% or more, and a slip resistance coefficient (CSR value) is set to be 0.8 or more even in an oil sprayed state to make the non-slip tread plate 1.SELECTED DRAWING: Figure 1
【課題】作業床、排水溝蓋の上に油脂成分や砂塵成分が付着していても、作業員が歩行し又は作業する際に滑りにくい踏板を提供すること【解決手段】複数の列をなして整列された打ち抜き孔１０を有するステンレス鋼板からなる滑り止め踏板１において、打ち抜き孔１０の周囲の直立部１１を鋭く切り立たせて靴底に食い込みやすいようにした。具体的には、直立部１１の幅を１．５ｍｍとさせると共に、直立部１１の頂部に刻み目を有する尖頭部１８を備えさせた。更に直立部１１の外面側を、滑り止め踏板１の表面に対して４５度よりも鋭い傾斜角度をなす尖頭部とさせた。また、打ち抜き孔１０の開口率を７％以上とさせ、油散布状態においても滑り抵抗係数（ＣＳＲ値）を０．８以上とさせ滑り止め踏板１とした。【選択図】図１
