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
