Document Type and Number:
Japanese Patent JP2016035180
Kind Code:
A
Abstract:
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
