In the elevator base device for a base-isolated building constructed as described above, the car guide rails and the counterweight guide rails are arranged vertically at all times, that is, when the base isolation device is not deformed in the horizontal direction. The counterweight is moved up and down. In addition, as shown in FIG. 1, the base entrance 3 and the hoistway entrance 4 are always arranged at a predetermined distance from each other and arranged in a vertical posture.
[0017]
The hoistway side floor board 13 is superposed on the base side floor board 8 and the hoistway side ceiling board 16 is superposed on the base side ceiling board 9. Further, the hoistway side wall plate 19 is arranged on the inner surface of the boarding passage 7 in the base side wall plate 11, and both the base side wall plate 11 and the hoistway side wall plate 19 are moved in the direction of passage of the boarding passage 7 by the engagement mechanism 23. Is engaged in a displaceable manner and in a state in which the displacement is restricted in the entrance direction of the entrance / exit passage 7.
[0018]
Further, the pivot side edge 12 of the base side wall plate 11 and the pivot side edge 22 of the hoistway side wall plate 19 are formed in an arc shape centering on the respective pivot axis in the horizontal cross section and correspond to each other. It is provided facing and adjacent to the side edge of the entrance / exit. With the above-described configuration, the entrance / exit passage 7 having a floor surface, a wall surface, and a ceiling surface without an extra gap is formed between the base entrance 3 and the hoistway entrance 4 at all times as shown in FIGS. The
[0019]
And when an earthquake and a strong wind generate | occur | produce a horizontal direction deformation | transformation at the time of a strong wind, and the base building 1 and a base isolation building are displaced relatively, the base building 1, ie, the base doorway 3, and the hoistway doorway 4, ie, A relative displacement occurs between the hoistway 2 and the hoistway 2. At this time, the corresponding members of the boarding passage 7 such as the base side floor board 8 and the hoistway side floor board 13 constituting the boarding passage 7 are relatively displaced, and correspond to the relative displacement of the base building 1 and the hoistway 2.
[0020]
When a relative displacement in the frontage direction occurs between the base entrance 3 and the hoistway 2 at the time of an earthquake or the like, for example, the base side wall plate 11 is illustrated with respect to the side edge of the base entrance 3. 4 and the outer surface of the pivot side edge 12 of the base side wall plate 11 is formed in an arc centered on the vertical axis 10 when displaced from the state shown in FIG. 3 to the state shown in FIG. Therefore, the gap between the side edge of the base entrance 3 and the pivoting side edge 12 does not expand.
[0021]
For this reason, at the time of relative displacement in the frontage direction of the two persons at the time of an earthquake or the like, the entrance / exit passage 7 provided between the two persons follows the relative displacement of the two persons, and is extraneous to the side edge of the entrance / exit. Without any gaps. Therefore, since a gap is widened between the constituent members of the entrance / exit passage 7 due to the relative displacement of the two persons at the time of an earthquake or the like, it is possible to prevent occurrence of a problem that foreign matter is caught.
[0022]
【The invention's effect】
As the invention has been described above, the seismic isolation building body that is supported via a vibration isolating apparatus to the base architecture body, a hoistway this seismic isolation building body disposed facing the base construction material provided A boarding passage provided between the base building and the hoistway, a hoistway doorway formed on the hoistway and forming one side of the boarding passage, and the other side of the boarding passage formed on the base building The base entrance / exit, one side pivoted to the side edge of the hoistway entrance / exit via a vertical axis , the other side projecting toward the base entrance / exit , and one side to the side entrance of the base entrance / exit A base side wall plate that is pivotally attached via a vertical axis, the other side projects toward the hoistway entrance and exits and overlaps with the other side of the hoistway side wall plate, and is provided on the back surface of both side wall plates. Enables relative displacement in the passage direction of the passage, and the entrance / exit passages on both side wall plates An engagement mechanism that engages in a state that restrains relative displacement in the frontage direction, and an end surface on one side of the hoistway side wall plate, and an outer surface thereof is connected to one side of the hoistway side wall plate in a horizontal cross section. It is formed in an arc shape centering on the pivoting vertical axis, and is provided on the pivoting side edge on the side of the hoistway facing and adjacent to the side edge of the hoistway entrance and on one end face of the base side wall plate. In the horizontal cross section, the outer surface is formed in an arc shape centering on the vertical axis that pivots on one side of the base side wall plate, and faces the side edge of the base doorway and is close to the base building side pivot. A wear side edge is provided.
[0023]
As a result, the base entrance / exit and the hoistway entrance / exit are normally arranged at a predetermined distance from each other, and are arranged in a vertical posture so that the hoistway side floor board is superposed on the base side floor board, and the hoistway side ceiling board is placed on the base side ceiling board. The hoistway side wall plate is superposed and disposed on the base side wall plate. And the entrance / exit passage which has a floor surface, a wall surface, and a ceiling surface without an excessive clearance gap at any time between a base entrance / exit and a hoistway entrance / exit is formed. In the event of an earthquake or strong wind, horizontal deformation occurs in the seismic isolation device, and when the base building and seismic isolation building are relatively displaced, the base building, that is, the base entrance and the hoistway entrance, that is, the hoistway A relative displacement occurs between persons. At this time, the corresponding members of the entrance / exit passages such as the base side floor board and the hoistway side floor board constituting the entrance / exit passages are relatively displaced to correspond to the relative displacement of the two persons. Further, since the outer surface of the pivoting side edge of the wall plate such as the base side wall plate is formed in an arc centered on the vertical axis, when the wall plate is rotationally displaced with respect to the side edge of the doorway, the doorway The gap between the side edge and the pivot side edge does not expand. Accordingly, the gap between the constituent members of the entrance / exit passage is widened due to the relative displacement of the two persons at the time of an earthquake or the like, so that it is possible to prevent the occurrence of a problem that foreign matter is caught.
