FIXING RETAINER FOR GRATING
To provide a fixing retainer for a grating that reduces the number of component parts to achieve cost reduction.SOLUTION: A fixing retainer for a grating comprises: a base member 2 fixed and attached to a pair of adjacent main members 11 of a grating 1; a nut-attached pressing member 4, in which a second plate part 42 bending toward a back surface at an inner obtuse angle when viewed from the front extends from a tip side of a first plate part 41 having a through-hole, having a nut 5 integrally fastened to the back surface of the first plate part with a center of a hole opening of the through-hole aligned with the center of a hole opening of a female threaded hole; and a bolt 6 screwed into the nut with a bolt head disposed on an upper surface side of a flat plate part and a bolt shaft loosely inserted into a permeation-hole and the through-hole. With respect to a gutter covered with the grating, the fastening of the bolt inserted through the permeation-hole and the through-hole and the nut brings a surface-side base end of the first plate part into contact with a lower surface of the flat plate part, and with this contact portion as a fulcrum, the second plate part rotates upward and protrudes laterally, thereby pressing a side wall 81 of the gutter.SELECTED DRAWING: Figure 5
【課題】構成部品を減らしてコスト低減を図るグレーチングの固定保持具を提供する。【解決手段】グレーチング１の隣り合う一対の主部材１１に取付け固定されるベース部材２と、通孔を設けた第一板部４１の先端側から正面視で内角が鈍角の角度で裏面側へ屈曲した第二板部４２が延在する押圧部材４にして、前記第一板部に係る裏面に通孔の孔口と雌ネジ孔の孔口との中心を合わせたナット５が固着一体化したナット付き押圧部材と、前記平板部の上面側にボルト頭を配して、ボルト軸を前記透孔及び前記通孔に遊挿し前記ナットに螺合するボルト６とを具備し、グレーチングで蓋をした側溝に対し、前記透孔及び前記通孔に遊挿した該ボルトと前記ナットとの締付けにより、前記平板部の下面に前記第一板部の表面側基端が当たり、この当たり部分を支点に前記第二板部が上動し且つ側方へ張り出すように回動し、該側溝の側壁８１を押圧する。【選択図】図５
