WATERSTOP DOOR
PROBLEM TO BE SOLVED: To maintain good water tightness between doors.SOLUTION: A waterstop door includes an annular frame body 10 having an opening at the center side, and a first door body 21 and a second door body 22 disposed at both sides to be water-tightly closed with the periphery sides overlapped on the frame body 10. Onto the door end side of the first door body 21 that revolves first to be closed, the door end side of the second door body 22 that revolves afterward to be closed is water-tightly pressed. The flexural strength in the vertical direction of the first door body 21 within a prescribed width times one on the door end side is larger than the flexural strength in the vertical direction of the second door body 22 within the same width on the door end side.SELECTED DRAWING: Figure 5
【課題】 扉間の水密性を良好に維持する。【解決手段】 中央側に開口を有する環状の枠体１０と、枠体１０に周縁側を重ね合わせて水密に閉鎖される左右の第１扉体２１及び第２扉体２２とを備え、先に回動し閉鎖した第１扉体２１の戸先側に、後から回動し閉鎖する第２扉体２２の戸先側を水密に押し付けるようにした止水扉であって、第１扉体２１の戸先側における所定幅Ｘ１内の上下方向の撓み強度を、第２扉体２２の戸先側における同幅内の上下方向の撓み強度よりも大きくしている。【選択図】 図５
