PROBLEM TO BE SOLVED: To provide a grating cover fixing device capable of fixing a grating cover and a cover receiving frame in a stable state.SOLUTION: The grating cover fixing device comprises: a connecting projection 11 that is protruded from a lower surface of a grating cover 31 and has a fixing plate portion forming a receiving gap 19 between the fixing plate portion and the lower surface of the grating cover, and an extended rod portion 21 that is placed across left and right cover receiving frames 41, 41 and has a connecting recessed portion 23 positioned directly below the connecting projection 11, wherein the grating cover 31 is fixed to the cover receiving frames 41, 41 by screwing a screw portion 6 of a fixing bolt 5 into a connecting concave portion 23, a head 7 of the fixing bolt is accommodated in an accommodation gap 19, and the screw portion 6 of the fixing bolt is inserted into an insertion hole of the fixing plate portion. The above configuration of the grating cover fixing device enables stable fixation of the grating cover 31 to the cover receiving frames 41, 41, and can hold this fixed state for a long time.SELECTED DRAWING: Figure 1
【課題】グレーチング蓋と蓋受枠との安定した固定状態が得られるグレーチング蓋の固定装置を提供する。【解決手段】グレーチング蓋３１の下面から突成され、該下面との間に収容間隙１９を形成する固定板部を備えてなる連結突部１１と、左右の蓋受枠４１，４１に差し渡され、連結突部１１の直下に位置する連結凹部２３を備えてなる差渡杆部２１とを具備し、収容間隙１９に頭部７が収容され且つ固定板部の挿通穴に螺子部６が挿通された固定用ボルト５の該螺子部６を、前記連結凹部２３に螺着させることにより、グレーチング蓋３１を蓋受枠４１，４１に固定するものである。かかる構成によれば、グレーチング蓋３１を蓋受枠４１，４１に安定して固定でき、この固定状態を長期に亘って保持できる。【選択図】図１
