ESCAPE DOOR
To provide an escape door that enables a door panel to be smoothly opened even if a wind pressure in a roadway tunnel acts on a door.SOLUTION: A door panel is double doors consisting of a wide first door body 3 that opens on an evacuation tunnel side B and a narrow second door body 4. An opening for a man way 5 is formed on the first door body 3. A splice plate 15, which closes a clearance between a door-end side end face (a first portion 303A of an outer depth face) of the first door body 3 and a door-end side end face 43 of the second door body 4 when the door panel is in a closing posture, is disposed on a roadway tunnel side of a door-end side portion of the wide first door body 3. The narrow second door body 4 can be opened earlier than the wide first door body 3.SELECTED DRAWING: Figure 6
【課題】車道トンネル内の風圧力が扉に作用している場合であっても、良好に開き扉の開放を可能とする避難扉を提供する。【解決手段】開き扉は、避難連絡坑側Ｂに開放される幅広の第１扉体３と幅狭の第２扉体４とからなる両開き扉であり、人道用開口部５が第１扉体３に形成されており、幅広の第１扉体３の戸先側部位の車道トンネル側には、開き扉の閉鎖姿勢時において、第１扉体３の戸先側端面（外側見込面の第１部分３０３Ａ）と第２扉体４の戸先側端面４３との間の隙間を塞ぐ目板部１５が設けてあり、幅狭の第２扉体４は、幅広の第１扉体３よりも先に開放可能となっている。【選択図】図６
