MAIN MEMBER WITH PERFORATED PROTRUSION FOR GRATING
PROBLEM TO BE SOLVED: To provide a main member with a perforated protrusion for a grating, which has a non-slip function provided in itself, and which can exert a non-slip effect without failure by securing an edge part.SOLUTION: A main member with a perforated protrusion for a grating includes: a strip-shaped steel upper plate part 2 that is arranged in a horizontal direction; steel side plate parts 3 and 3 that are each extended downward from both side edges 21 and 21 in a strip width direction of the upper plate part 2; and a steel perforated protrusion 4 that has a through-hole 40 vertically passing through the upper plate part 2 and that has a peripheral edge 41 of the through-hole 40 formed in a cylindrical shape to an upper side from a surface 2a of the upper plate part 2. The plurality of perforated protrusions 4 are provided away from one another in the longitudinal direction of the upper plate part 2.
【課題】主部材そのものに滑り止め機能をもたせ、しかもエッジ部分を確保して滑り止め効果をいかんなく発揮できるグレーチング用孔開き突起付き主部材を提供する。【解決手段】水平配設される帯状の鋼製上板部2と、該上板部2の帯幅方向の両側縁21,21から下方へそれぞれ延在する鋼製側板部3,3と、前記上板部2に上下方向へ貫通する透孔40を有して、該透孔40の周縁41を上板部2の表面2aから上方側へ筒状に形成される鋼製孔開き突起4と、を具備し、且つ該孔開き突起4が、前記上板部2の長手方向へ向け、互いに離間させて複数設けられてなる。【選択図】図１
