Description

  In the present invention, a base isolation structure is supported on a base building via a base isolation device, and a hoistway is formed in the base building and the base isolation structure, and a boarding passage is provided between the hoistway and the building. The present invention relates to a movable landing device for an elevator for a seismically isolated building, particularly a movable floor portion thereof.

  In the conventional elevator base station for base-isolated buildings, the base-isolated building supported by the base building via the base-isolating device and the base-isolated building are arranged in a fitted state. A hoistway is provided, and an entrance / exit passage is disposed between the building 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.

  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.

  This accommodates changes in the distance between the base building and the hoistway during an earthquake or strong wind. With such a configuration, the entrance / exit passage is configured to be displaced or expanded / contracted when the both are relatively displaced in the horizontal direction during an earthquake or the like (see, for example, Patent Document 1). As another prior art, even if the left and right buildings are swung in the left and right direction due to an earthquake or the like, they can absorb the wobbling movement, and are small in a plurality of barrier curtain support bars that always move at a predetermined interval. There has been proposed a curtain device in which the curtain is fixed by bending (see, for example, Patent Document 2).

Japanese Patent Laid-Open No. 11-171429 (summary, FIG. 1) JP-A-11-81499

In conventional elevator bases for base-isolated buildings, when a relative displacement occurs between the base building and the hoistway at the time of an earthquake, the hoistway is connected to the base doorway of the base building. A displacement that inclines in a direction in which there is a difference between the distance to the upper 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 with respect to the base entrance.
In this way, in the conventional entrance / exit constructed by the base plate, the hoistway plate, and the intermediate plate when the tilting inclination of the hoistway occurs in the entrance / exit direction with respect to the base entrance / exit, the base entrance / exit based on the tilting inclination of the hoistway And the response to the relative displacement of the hoistway entrance is insufficient. That is, the base plate, the hoistway plate, and the intermediate plate are inclined in the direction in which one side in the width direction moves up and down. For this reason, there has been a problem that the sliding displacement between them becomes unsmooth and the member is deformed or an unpleasant squeak noise is generated. In addition, in order to solve such a problem, there has been proposed one that smoothly slides and displaces when an earthquake occurs, but the movable floor portion of the landing device does not return to the normal position after the earthquake occurs, and it becomes uneven, so it looks good Deteriorate. Therefore, it was necessary to reset the movable floor portion, which was very time-consuming. In addition, other prior art screen curtain devices could not be diverted as they are to the movable floor portion of the movable landing device of the seismic isolation building elevator.

  The present invention has been made in order to solve such problems, and the relative relationship between the base entrance and the hoistway entrance associated with the occurrence of tilting of the hoistway in the entrance and exit directions with respect to the base entrance of the base building. It is an object of the present invention to provide a movable landing device for an elevator for a base-isolated building that can cope with displacement with a movable floor portion of a boarding / exiting passage without any abnormality and can return to a normal position after an earthquake.

  In the movable landing device for an elevator for a base-isolated building according to the present invention, the base-isolated building is supported by the base building via the base-isolating device, and a hoistway is formed in the base and the base-isolated building, A boarding passage is provided between the hoistway and the building, a fixed doorway is provided on the building side of the boarding passage, and a movable doorway is provided on the hoistway side of the boarding passage. A plurality of movable floor boards provided on the hoistway side of the entrance / exit passage, and arranged so as to be constantly superposed on the upper surface of the fixed floor board, A plurality of movable ceilings and movable side walls, which are respectively provided on the hoistway side of the passage and are slidably fitted inside the fixed ceiling and the fixed side walls, and between the fixed floor plate and each movable floor plate, It is obtained by a movable floor for telescopic connecting link to evenly slidably displaced between each other floorboards.

  Further, the pivot pin of the telescopic connecting link for the movable floor plate, the fixed floor plate, and each movable floor plate are connected by a spherical seat mechanism.

  Also, provided between the fixed floor plate and each movable floor plate, between the fixed ceiling and each movable ceiling, and between the fixed side wall and each movable side wall, between each movable floor plate and between each movable ceiling. , And an expansion / contraction link for slidably displacing between the movable side walls.

  The telescopic connection link is composed of a pantograph operation mechanism.

  In addition, one extension link link is arranged between the fixed floor plate and each movable floor plate in the vertical direction, and two pieces are arranged at horizontal intervals between the fixed ceiling and each movable ceiling, and the fixed side wall. And two movable side walls are vertically spaced apart from each other.

  Further, the movable floor plate has a multi-layer structure made of a plurality of flat plate-like stainless steel plates, and the movable ceiling and the movable side wall have a multi-layer structure made of a plurality of gate-type stainless steel plates.

  The present invention is provided on the building body side of the entrance / exit passage, and is provided on the fixed floor board, the fixed ceiling and the fixed side wall forming the fixed entrance and the hoistway side of the entrance / exit passage, and is arranged so as to be constantly polymerized on the upper surface of the fixed floor board.
