DITCH COVER RECEIVING FRAME AND WORK METHOD FOR DITCH COVER RECEIVING FRAME
To make a nut and the surroundings thereof less likely to be clogged with mud and sand, and even if clogged, allow the mud and sand to be easily discharged by protruding a nut structure part from a receiving frame to the inside of a groove.SOLUTION: A ditch cover receiving frame has a nut structure part 20 provided on an inner vertical surface 12 of a receiving frame 10 provided on the top of a groove 40. The nut structure part includes an upper plate 22 provided with an upper hole 23 configured larger than the screw diameter of a bolt 3, a lower plate 24 provided with a lower hole 25 with a position and size corresponding to the upper hole, and a side plate 26 joining the upper plate and the lower plate at a predetermined distance. The ditch cover receiving frame also includes a box-shaped member 21 protruding from the inner longitudinal surface toward the inside of the groove, an anti-rotation plate 28 placed between the upper and lower plates, the edge of which is in contact with the side plate so that it cannot turn at or more than a predetermined angle and having a through hole 29 through which the bolt penetrates, and a nut 30 provided at a position corresponding to the through hole of the anti-rotation plate.SELECTED DRAWING: Figure 1
【課題】ナット構造部を受枠より溝の内側に突出させることで、ナット及びその周辺に泥や砂などが詰まりにくく、仮に詰まっても容易に排出させることができるようにする。【解決手段】溝４０の上部に設けられる受枠１０の内縦面１２に設けられるナット構造部２０を備え、前記ナット構造部は、ボルト３のねじ径より大きく構成される上孔２３を備える上板２２、前記上孔に対応する位置と大きさの下孔２５を備える下板２４、及び前記上板と前記下板とを所定の距離を空けて接合する側板２６を備え、前記内縦面から溝の内側に向かって突出する箱状部材２１と、前記上板と前記下板との間に配置され、その縁が前記側板に当接されることで所定の角度以上回動せずかつ前記ボルトが貫通する貫通孔２９を備える回り止め板２８と、前記回り止め板の前記貫通孔に対応する位置に設けられるナット３０と、を備える。【選択図】図１
