GRATING MEMBER AND MANUFACTURING METHOD OF GRATING MEMBER
PROBLEM TO BE SOLVED: To provide a grating member which can be manufactured by performing cold rolling on a metal round bar with a pair of rollers to work-harden substantially the entire region of the round bar and improve the strength thereof, and by forming both end parts of the bar into a convex arc-shaped cross section by leaving a curve of the round bar at both of the end parts, thereby providing a soft feeling without having an elastic material layer and the like when touched by a sole and making a manufacturing process of the cold rolling simple to achieve reduction of manufacturing costs.SOLUTION: A grating member used in a grating comprises a flat plate formed by performing cold rolling on a metal round bar with a pair of rollers. The flat plate includes: a pair of side surfaces which are cold-rolled; and both end parts formed by being horizontally extended in the cold rolling and having an arc-shaped cross section formed by leaving a curve of the round bar.
【課題】金属からなる丸棒を対向する一対のロールで冷間圧延することにより、略全域にわたり加工硬化させ、強度を向上させるとともに、両端部に丸棒の曲面を残すことで、当該両端部を凸状の断面円弧状とし、弾性材層等を設けなくとも足の裏にあたる感触を柔らかくし、さらに冷間圧延の製造工程を簡素なものにすることで製造コストを低減させる。【解決手段】グレーチングに用いられるグレーチング部材において、金属材料の丸棒を対向する一対のロールで冷間圧延することで形成された平板からなり、前記平板は、冷間圧延された一対の側面と、前記冷間圧延による横広がりにより形成され、前記丸棒の曲面が残された断面円弧状をなす両端部と、を備える。【選択図】図１
