本実施形態に係る開き扉は、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（開口部５）は第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Ａに、開き扉の閉鎖姿勢時において、上記隙間を塞ぐ目板部１５を設けることによって、開き扉の閉鎖姿勢時において、幅狭の第２扉体４を、幅広の第１扉体３よりも先に開放させることを可能としている。 The hinged door according to this embodiment is a double door composed of a wide first door body 3 and a narrow second door body 4 that open to the evacuation tunnel side B, and has a pedestrian opening (opening 5 ) is formed on the first door body 3, and a grid plate portion 15 is provided on the roadway tunnel side A of the door tip side portion of the wide first door body 3 to close the gap when the hinged door is in the closed posture. This enables the narrow second door body 4 to be opened earlier than the wide first door body 3 when the swing door is in the closed position.

第１扉体３の戸先側縦枠３０の避難連絡坑側Ｂの端部には、外側見込面３０３を越えて内側見込面３０２から離間する方向に突出する突出部３０Ａが形成されているが、突出部３０Ａは、第２扉体４の戸先側部位の回動軌跡と干渉しないように形成されている。突出部３０Ａは、第１扉体３の戸先側縦枠３０の外側見込面３０３の避難連絡坑側Ｂの端部（第２部分３０３Ｂの端部）から突成されており、開き扉の閉鎖姿勢時において、第２扉体４の戸先側部位（戸先側端面４３）は、第１扉体３の戸先側縦枠３０の外側見込面３０３の車道トンネル側Ａの端部（第１部分３０３Ａ）に対向している。したがって、突出部３０Ａの突出寸法（外側見込面３０３からの突出寸法）がより小さければ、突出部３０Ａと第２扉体４の戸先側部位の回動軌跡とが干渉しにくくなり、また、開き扉の閉鎖姿勢時において、第２扉体４の戸先側部位から突出部３０Ａまでの距離（外側見込面３０３の見込寸法）がより長ければ、突出部３０Ａと第２扉体４の戸先側部位の回動軌跡とが干渉しにくくなる。このような突出部３０Ａは、突出部３０Ａの突出寸法（外側見込面３０３からの突出寸法）、及び、開き扉の閉鎖姿勢時における第２扉体４の戸先側部位から突出部３０Ａの背面３０５までの距離（外側見込面３０３の見込み法）を考慮して形成することができる。この距離について言うと、第１扉体３には、第１見付面３１から避難連絡坑側Ｂに突出するように引戸枠の戸尻側縦枠８、上枠９、下枠１０が設けてあり、戸先側縦枠３０は、前記引戸枠を越えて避難連絡坑側Ｂに延びており、その端部に内側見付面３００及び突出部３０Ａが形成されており、例えば、特許文献１に開示されている戸先側縦枠の外側見込面に比べて大きい見込寸法を備えている。 A protruding portion 30A is formed at the end of the door leading side vertical frame 30 of the first door body 3 on the side of the evacuation passage side B and protrudes in a direction away from the inner viewing surface 302 beyond the outer viewing surface 303. However, the projecting portion 30A is formed so as not to interfere with the locus of rotation of the portion of the second door 4 on the side of the door. The protruding portion 30A protrudes from the end of the evacuation connecting shaft side B (the end of the second portion 303B) of the outer projection surface 303 of the door tip side vertical frame 30 of the first door body 3, and is used as the swing door. In the closed position, the door tip side portion (door tip side end surface 43) of the second door body 4 is aligned with the road tunnel side A end portion ( It faces the first portion 303A). Therefore, if the projection dimension of the projecting portion 30A (the projecting dimension from the outer projection surface 303) is smaller, interference between the projecting portion 30A and the rotational trajectory of the portion of the second door body 4 on the door end side becomes less likely to interfere with each other. When the swing door is closed, the longer the distance from the door tip side portion of the second door body 4 to the protruding part 30A (the projected dimension of the outer projected surface 303), the longer the protruding part 30A and the second door body 4 are. Interference with the rotation trajectory of the front side portion becomes difficult. Such a projecting portion 30A has a projecting dimension of the projecting portion 30A (a projecting dimension from the outer projected surface 303), and a back surface of the projecting portion 30A from the door tip side portion of the second door body 4 when the hinged door is in the closed posture. It can be formed considering the distance to 305 (outside prospective surface 303 prospective method). Regarding this distance, the first door body 3 is provided with a vertical frame 8, an upper frame 9, and a lower frame 10 of the sliding door frame so as to protrude from the first viewing surface 31 toward the evacuation passageway side B. The door tip side vertical frame 30 extends beyond the sliding door frame to the side of the evacuation passageway B, and has an inner side surface 300 and a projecting portion 30A at its end. 1 is provided with a large projected dimension compared to the outer projected surface of the door tip side vertical frame disclosed in 1.

第１スライド扉６の上端に固定したハンガーローラＨＲ１は、ワイヤαを挿通させる部位を備えると共に、ワイヤαには、挿通部位の戸尻側に位置して当接体（金具）が固定されている。第１スライド扉６の戸尻側（開放方向）への移動時には、前記挿通部位がワイヤα上の当接体を押すことで、ワイヤαは戸尻側（開放方向）へ引き出され、巻取装置９２に巻かれていく。ワイヤαの戸先側（閉鎖方向）への移動に伴ってワイヤαに固定した当接体がハンガーローラＨＲ１の挿通部位に当接して、ハンガーローラＨＲ１を戸尻側から戸先側に向かって押すことで、第１スライド扉６が戸先側（閉鎖方向）に移動するようになっている。閉鎖姿勢にある第１スライド扉６を自閉装置ＤＣ３の付勢力に抗して手動で戸尻側（開放方向）にスライド移動させると、ワイヤαが自閉装置ＤＣ３から引き出されながら戸尻側へ移動して、第１スライド扉６、第２スライド扉７が開放姿勢となる。第１スライド扉６、第２スライド扉７は、例えばタイマーによって、開放姿勢を所定時間維持した後に、自閉装置ＤＣ３の閉鎖力によって、ワイヤαが閉鎖方向へ移動することに伴って戸先側へスライド移動して、開口部５を閉鎖する。 A hanger roller HR1 fixed to the upper end of the first slide door 6 has a portion through which the wire α is inserted, and a contacting body (metal fitting) is fixed to the wire α, positioned on the door bottom side of the insertion portion. there is When the first slide door 6 is moved toward the door bottom side (opening direction), the wire α is pulled out toward the door bottom side (opening direction) by the insertion portion pushing the abutting body on the wire α, and is wound up. It is wound around the device 92 . As the wire α moves toward the door tip side (closing direction), the abutting body fixed to the wire α comes into contact with the insertion part of the hanger roller HR1, and the hanger roller HR1 moves from the door trailing edge side toward the door tip side. By pushing, the first slide door 6 is moved toward the door tip (closing direction). When the first slide door 6 in the closed posture is manually slid toward the door tail side (opening direction) against the biasing force of the self-closing device DC3, the wire α is pulled out from the self-closing device DC3 and moved toward the door tail side. , and the first slide door 6 and the second slide door 7 are opened. After the first slide door 6 and the second slide door 7 are kept open for a predetermined time by a timer, for example, the wire α moves in the closing direction due to the closing force of the self-closing device DC3. to close the opening 5.

このように構成された避難連絡坑ドアにおいて、通常時には、閉鎖姿勢にある開き扉によって開口部１が閉鎖され、閉鎖姿勢にある引き戸によって開口部５が閉鎖されている。災害時等に車両用開口部を形成したい場合には、グレモンハンドルＨ２を回動して第２扉体４の閉鎖姿勢のロックを解除し、第２扉体４を避難連絡坑側Ｂに開放して、係止ロッドＲ２を下動して第２扉体４の開放姿勢を維持し、グレモンハンドルＨ１を回動して第１扉体３の閉鎖姿勢のロックを解除し、第１扉体３を避難連絡坑側Ｂに開放して、係止ロッドＲ１を下動して第１扉体３の開放姿勢を維持することで、車両用開口部を形成する。開き扉の開放時において、第２扉体４のグレモンハンドルＨ２、第１扉体３のグレモンハンドルＨ１が共に正面（第１見付面４１、内側見付面３００）に設けてあるので、グレモンハンドルＨ２、Ｈ１を掴んで行う第２扉体４、第１扉体３の開放操作性が良い。第２扉体４、第１扉体３の開放に先立って、引き戸（第１スライド扉６、あるいは、第１スライド扉６及び第２スライド扉７）を開放し、閉鎖姿勢の開き扉の面部に作用する圧力を軽減してから第２扉体４を開放してもよい。 In the thus constructed evacuation tunnel door, the opening 1 is normally closed by the hinged door in the closed position, and the opening 5 is closed by the sliding door in the closed position. When it is desired to form an opening for a vehicle in the event of a disaster, etc., the gremon handle H2 is turned to unlock the second door body 4 in the closed posture, and the second door body 4 is opened to the evacuation tunnel side B. Then, the lock rod R2 is moved downward to maintain the open posture of the second door body 4, the gremon handle H1 is rotated to unlock the closed posture of the first door body 3, and the first door body 3 is opened to the evacuation passage side B, and the locking rod R1 is lowered to maintain the open position of the first door body 3, thereby forming the vehicle opening. When the hinged door is opened, both the Gremone handle H2 of the second door member 4 and the Gremone handle H1 of the first door member 3 are provided on the front surface (the first viewing surface 41 and the inner viewing surface 300). The operability of opening the second door 4 and the first door 3 by gripping the handles H2 and H1 is good. Prior to opening the second door body 4 and the first door body 3, the sliding door (the first sliding door 6 or the first sliding door 6 and the second sliding door 7) is opened, and the face portion of the opening door in the closed posture The second door body 4 may be opened after the pressure acting on is reduced.

幅狭の第２扉体４を、幅広の第１扉体３よりも先に開放可能としたので、車道トンネル内の風圧力が閉鎖姿勢の第１扉体３（及び閉鎖姿勢の第１スライド扉６及び第２スライド扉７）及び第２扉体４に作用している場合であっても、より風圧の影響が少ない第２扉体４を先に開放し、次いで、風圧の影響を軽減した状態で第１扉体３を開放させることができる。また、第２扉体４の開放に先立って、第１扉体３の引き戸（第１スライド扉６、あるいは、第１スライド扉６及び第２スライド扉７）を開放し、第２扉体４の面部に作用する圧力を軽減（差圧の軽減）してから第２扉体４を開放してもよい。 Since the narrow second door body 4 can be opened earlier than the wide first door body 3, the wind pressure in the roadway tunnel is applied to the first door body 3 in the closing posture (and the first sliding door body in the closed posture). Even when the door 6 and the second sliding door 7) and the second door 4 are affected, the second door 4, which is less affected by the wind pressure, is opened first, and then the influence of the wind pressure is reduced. In this state, the first door body 3 can be opened. Prior to opening the second door body 4, the sliding door of the first door body 3 (the first slide door 6 or the first slide door 6 and the second slide door 7) is opened, and the second door body 4 is opened. The second door 4 may be opened after reducing the pressure acting on the surface of (reducing the differential pressure).

災害時等に人道用開口部を形成したい場合には、取手Ｈ３を掴んで第１スライド扉６、第２スライド扉７を開放することで、開き扉の閉鎖姿勢を維持したままで、人道用開口部を形成することができる。 When it is desired to form an emergency opening in the event of a disaster, the first slide door 6 and the second slide door 7 can be opened by grasping the handle H3, thereby maintaining the closed position of the opening door. An opening can be formed.
