PASSAGE STRUCTURE
PROBLEM TO BE SOLVED: To provide a passage structure capable of preventing the reduction of the width of a passage when an earthquake occurs, and improving the safety of a person who moves at stairs when the earthquake occurs.SOLUTION: In a passage structure 1 in which an upper structure 20 and a lower structure 10 are configured so as to be displaceable with different behaviors, the lower structure 10 includes: a first floor part 11; a second floor part 12 positioned above the first floor part 11; and a lower stair part 13 by which the first floor part 11 is communicated with the second floor part 12 so as to lift up and down, and the first floor part 11, the second floor part 12, and the lower stair part 13 are configured so as to be displaceable with the same behavior, and an effective passage E through which persons mutually move at the first floor part 11 and the second floor part 12 is formed, and mutual intervals between the positions of both end parts in a width direction of the lower stair part 13 when no earthquake occurs and the positions of both end parts in a width direction of the effective passage E when no earthquake occurs are set to intervals not less than the maximum relative anticipated displacement.SELECTED DRAWING: Figure 3
【課題】地震時における通路の幅員の減少を防止でき、地震時に階段部を移動する者の安全性を向上できる通路構造を提供すること。【解決手段】通路構造１は、上部構造体２０と下部構造体１０とが異なる挙動で変位可能な通路構造１であって、下部構造体１０は、第１床部１１と、第１床部１１よりも上方に位置する第２床部１２と、第１床部１１と第２床部１２とを相互に昇降可能に連絡する下部階段部１３と、を備え、第１床部１１、第２床部１２、及び下部階段部１３は、同一の挙動で変位可能であり、第１床部１１と第２床部１２とを相互に移動するための有効通路Ｅが形成され、下部階段部１３の幅方向両端部の非地震時における位置と、有効通路Ｅの幅方向両端部の非地震時における位置との相互間隔を最大相対予想変位以上の間隔とした。【選択図】図３
