BACKGROUND OF THE INVENTION
In the present invention, a base isolation structure is supported by a base building via a base isolation device, and a hoistway is formed in the base building and the base isolation structure. The present invention relates to a landing device for an elevator for a base-isolated building provided with a passage.
[0002]
[Prior art]
In a conventional base station for base-isolated building elevators, a base-isolated building supported by the base building via a base-isolating device and a base-isolated building formed in a fitted state. A hoistway is provided, and an entrance / exit passage is disposed between the base building body and the hoistway. That is, a hoistway entrance / exit that is provided in the hoistway and forms one side of the entrance / exit passage is disposed, and a base portion that is provided in the base building and is disposed opposite the hoistway entrance / exit to form the other side of the entrance / exit passage A doorway is equipped.
[0003]
Then, one side of the base plate is held at the base entrance / exit and protrudes toward the hoistway entrance / exit, and one side of the hoistway plate is held at the hoistway entrance / exit and protrudes toward the base entrance / exit. Further, one side of the intermediate plate is engaged with the other side of the base plate, the other side of the intermediate plate is engaged with the other side of the hoistway plate, and the space between both the base plate and the hoistway plate is closed, The floor surface of the entrance / exit passage is formed by both and the intermediate plate.
[0004]
This accommodates changes in the distance between the base building and the hoistway during an earthquake or strong wind. With such a configuration, when the both are relatively displaced in the horizontal direction during an earthquake or the like, the entrance / exit passage is displaced or expanded / contracted. (For example, refer to Patent Document 1).

[Problems to be solved by the invention]
In conventional elevator bases for base-isolated buildings, when a relative displacement occurs between the base building and the hoistway during an earthquake, the hoistway is located above the base doorway. A displacement that inclines in a direction in which a difference occurs between the distance to the edge and the distance to the lower edge of the base entrance, that is, a tilting inclination in the direction along the entrance / exit direction of the entrance / exit occurs in the hoistway with respect to the base entrance.

For this reason, when the inclination which falls in the passage direction of the getting-on / off passage 7 generate | occur | produces in the movable hoistway frame 6, both the said sliding displacement is carried out smoothly. Further, since both of them are slid and displaced via the fixed-side upper guide body 38, the aesthetic appearance of the member can be maintained without causing damage such as scratches or peeling of the paint on the sliding portion.
[0036]
Therefore, the component members of the entrance / exit passage 7 correspond to the relative displacement of the hoistway entrance 16 and the fixed side entrance 19 due to an earthquake or the like without any abnormalities, and the above two parts are deformed or have an unpleasant squeak. Problems that occur can be solved. In addition, between the fixed side lower closing plate 39, the hoistway upper closing plate 46, the hoistway lower closing plate 49, and their opposing members, damage, deformation, and unpleasant squeak noise during sliding displacement Occurrence can be prevented.
