EVACUATION DOOR DEVICE FOR TUNNEL
To prevent actuation of an inverted L-shaped evacuation door 7 provided in a tunnel 1 from being hindered by receiving careless resistance, when the evacuation door 7 is displaced during an opening/closing operation.SOLUTION: First and second cushioning materials 19 and 20 for cushioning displacement by elastic deformation are interposed between a ceiling panel part 9 arranged so as to provide an upper side roller 11 on the ceiling panel part 9 of the evacuation door 7 and a fist bracket 17, and between the first bracket 17 and a second bracket 18.SELECTED DRAWING: Figure 6
【課題】トンネル１内に設けた逆Ｌ字形をした避難扉７が開閉作動中に姿勢変位した場合に、不用意な抵抗を受けて避難扉７の作動に支障を来さないようにする。【解決手段】避難扉７の天井パネル部９に上側ローラ１１を設けるため配される天井パネル部９と第一ブラケット１７とのあいだ、第一、第二ブラケット１７、１８同士のあいだに、弾性変形により変位の緩衝をする第一、第二の緩衝材１９、２０を介装する。【選択図】図６
