ESCAPE DOOR
To provide an escape door, even when wind pressure in a roadway tunnel is acting on the door, capable of favorably opening the door.SOLUTION: An escape door includes a door device that opens and closes a vehicle-passing-through opening for communicating an escape drift with a roadway tunnel, and a sliding door that opens and close a pedestrian-passing-through opening formed in the door device. Further the escape door includes a sliding door opening device 17 that moves the sliding door in an opening direction and movement restricting means (a winding device 18 provided with a locking device) that restricts the movement of the sliding door opening device 17 in the opening direction. The movement restriction by the movement restricting means (a winding device 18 having a lock device) is released in conjunction with an opening operation of the door device, and the sliding door opening device 17 automatically opens the sliding door when the door device is opened.SELECTED DRAWING: Figure 12
【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、良好に扉の開放を可能とする。【解決手段】避難連絡坑と車道トンネルを連通する車両用開口部を開閉する扉装置と、前記扉装置に形成された人道用開口部を開閉する引き戸と、を備えた避難扉において、引き戸を開放方向に移動させる引戸開放装置１７と、引戸開放装置１７による引き戸の開放方向の移動を規制する移動規制手段（ロック装置を備えた巻取装置１８）とを備え、移動規制手段（ロック装置を備えた巻取装置１８）による移動規制は、前記扉装置の開放操作に連動して解除され、前記扉装置の開放時に引戸開放装置１７によって引き戸を自動で開放する。【選択図】図１２
