DERRICKING GATE AND WATERTIGHT CONSTRUCTION OF DERRICKING GATE
To provide a watertight rubber having durability to make a base end side of a door body watertight.SOLUTION: A bottom watertight part 20 (watertight structure) of a derricking gate comprises: a movable side attachment part 21 that is provided to a base end 12 of a door body 10 and that has an attachment surface 21a which becomes horizontal when the door body 10 falls; a fixed side attachment part 22 that is fixed to a position downstream of the movable side attachment part 21 and that has a horizontal attachment surface 22a; a sheet-like watertight rubber 23 that is provided over the attachment surfaces 21a, 22a; a movable side pinching plate 26, a lower surface 26b of which pinches the watertight rubber 23 with the attachment surface 21a; a fixed side pinching plate 27, a lower surface 27b of which pinches the watertight rubber 23 with the attachment surface 22a; and a pressure uneven distribution mechanism 30 for unevenly distributing pinching pressure so that the pinching pressure applied to the watertight rubber 23 by the attachment parts 21, 22 and the pinching plates 26, 27 can be highest at edges 24a, 24b, and 25a of pinching regions 24, 25 in the pinching regions 24, 25 of the watertight rubber 23 pinched by the attachment parts 21, 22 and the pinching plates 26, 27.SELECTED DRAWING: Figure 2
【課題】扉体の基端側を水密する耐久性を有する水密ゴムを提供する。【解決手段】起伏ゲートの底部水密部20(水密構造)は、扉体10の基端12に設けられ、扉体10の倒伏時に水平となる取付面21aを有する可動側取付部21と、可動側取付部21よりも下流側の位置に固定され、水平な取付面22aを有する固定側取付部22と、取付面21a,22aの上に跨って設けられるシート状の水密ゴム23と、下面26bが取付面21aとの間で水密ゴム23を挟持する可動側挟持板26と、下面27bが取付面22aとの間で水密ゴム23を挟持する固定側挟持板27と、取付部21,22と挟持板26,27とで挟持される水密ゴム23の挟持領域24,25において、取付部21,22と挟持板26,27とによって水密ゴム23に作用する挟持圧力が、挟持領域24,25の縁部24a,24b,25aで最大となるよう挟持圧力を偏在させる圧力偏在機構30を備える。【選択図】図2
