PROBLEM TO BE SOLVED: To provide a fixing device for a grating lid that reduces an installation work burden and suppresses increase of wastes generated from the installation work.SOLUTION: A fixing device 1 for a grating lid comprises: a receiving frame connection part 2 provided on a horizontal receiving edge 35 of a support receiving frame 34, the receiving frame connection part including a fixing plate part 12 and a nut member 16 fixed on an undersurface of the fixing plate part 12; and a lid connection plate part 3 provided at a position corresponding to the receiving frame connection part 2 between adjacent main bars 52. A grating lid 51 is fixed on the support receiving frame 34 through the fixing plate part 12 and the lid connection plate part 3, by screwing a fixing bolt 25 into a nut member 16 after mounting the grating lid 51 on the right and left support receiving frames 34 and while disposing the lid connection plate part 3 directly above the receiving frame connection part 2. With the fixing device, no special work is required for installation. Therefore, a work burden and increase in wastes may be suppressed.SELECTED DRAWING: Figure 7
【課題】施工作業の作業負担を抑制でき、且つ該施工作業により生ずる廃棄物の増加を抑制し得るグレーチング蓋の固定装置を提案する。【解決手段】支持受枠３４の水平受縁３５上に、固定板部１２と該固定板部１２の下面に固定されたナット部材１６とを備えた受枠連結部２を設けると共に、隣合うメインバー５２間の、該受枠連結部２に対応する位置に、蓋連結板部３を設けてなり、グレーチング蓋５１を左右の支持受枠３４に乗載して、該蓋連結板部３を受枠連結部２の直上に配置した状態で、固定用ボルト２５を前記ナット部材１６に螺合することにより、前記固定板部１２と該蓋連結板部３とを介して、グレーチング蓋５１を支持受枠３４に固定するものである。かかる固定装置１によれば、施工の際に特別な作業を要しないことから、作業負担と廃棄物増加とを抑制できる。【選択図】図７
