BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1. FIG. 1 is a conceptual vertical cross-sectional view of an essential part of a hoistway showing an example of an embodiment of the present invention, and an elevator device is configured similarly to FIG. 7 described above except FIG.
In the figure, 1 is a base structure that is provided with an opening 2 and is constructed on the ground, 4 is a base isolation structure supported by the base structure 1 via a vibration isolation device 3, and 5 is a hoistway of an elevator, It is constructed integrally with the vibration-isolated building 4, the lower part is arranged in a fitted state with a gap formed in the opening 2 of the base building 1, and the bottom face 6 is provided at the lower end.

Reference numeral 8 is a main rope wound around a hoisting machine 7 and suspended in a hoistway 5. An elevating body 9 composed of a car is connected to one end of the main rope, and a counterweight 10 is connected to the other end. 11
Is a shock absorber which is provided upright on the bottom surface 6 of the hoistway 5 and is inserted into the through hole 12 of the bottom surface 6 with a gap formed in the horizontal direction.

Numeral 12 stands on the bottom surface 6 of the hoistway 5 and

In such a structure, the base structure 1
Since the shock absorber 11 is erected upright, the impact force when the lifting body 9 collides with the shock absorber 11 is directly transmitted to the base structure 1. Therefore, the impact force of the lifting body 9 and the shock absorber 11 does not act on the bottom surface 6 of the hoistway 5. As a result, the bottom surface 6 of the hoistway 5 can have a simple structure and the construction cost can be reduced. Further, the impact force due to the collision between the lifting body 9 and the shock absorber 11 does not reach the vibration isolation device 3, and the load capacity of the vibration isolation device 3 can be reduced.

The collision plate 14 is formed to have a horizontal dimension corresponding to the horizontal displacement amount of the hoistway 5 by the vibration isolator 3. Therefore, even if the vibration-isolated building 4, that is, the hoistway 5 is displaced in the horizontal direction with respect to the base structure 1, that is, the shock absorber 11 due to the earthquake, the collision plate 14 faces the upper surface of the shock absorber 11 normally.
