At this time, the pair of upper guide shoes 10 are pressed against the pair of car guide rails 2, respectively. That is, a pair of upper guide shoes 10 is combined with a pair of car guide rails 2, respectively. Accordingly, the pair of upper guide shoes 10, the pair of vertical columns 14, and the upper beam 15 are positioned.

17 is a perspective view showing a sixth positioning step in the mounting method according to Embodiment 1. FIG. Fig. 18 is a perspective view of the elevator in Fig. 17 viewed from a direction different from Fig. 17 .

The 6th positioning process is implemented after the 5th positioning process. In the sixth positioning process, first, the scaffolding device 23 is removed. Then, the car bottom 6 is raised to the second floor.

Thereafter, a pair of third car guide rail brackets 4c is attached to the pair of car guide rails 2 . Then, each car guide rail 2 is pressed against the corresponding upper guide shoe 10 . That is, a pair of car guide rails 2 is combined with a pair of upper guide shoes 10, respectively.

In addition, in the fourth positioning step, the pair of car guide rails and the pair of lower guide shoes 9 are combined to respectively position the second car guide rail brackets 4b.

Therefore, the position adjustment of the pair of car guide rails 2 can be easily performed without stretching piano wires in the hoistway 1 and without using guide rail gauges.

In addition, even when the landings are shifted between the floors or the landings are twisted in the horizontal plane, the position adjustment of the pair of car guide rails 2 can be performed based on the landings of the respective floors. Therefore, the intervals between the halls of each floor and the car bottom 6 can be made equal.

In particular, even when the existing hall sills 31 and 32 and the existing hall door frame 33 are retained, the distance between the hall and the car bottom 6 of each floor can be made equal.

Furthermore, by pre-attaching the emergency stop device 8, the pair of lower guide shoes 9, and the pair of car suspending sheaves 11 to the car bottom 6, it is possible to reduce the work on site. In addition, the assembly accuracy of the car bottom 6, the emergency stop device 8, the pair of lower guide shoes 9, and the pair of car suspension wheels 11 can be improved.

In addition, in the first positioning step, the car bottom 6 is connected to the first landing sill 31 via the car bottom connector 27 . Therefore, it is possible to more accurately position the car floor 6 with respect to the first landing sill 31 .

In addition, in the first positioning step, the pillars 21 are interposed between the car bottom 6 and the bottom 1a, and the height of the pillars 21 is adjusted so that the car bottom 6 becomes horizontal. Thereby, the load applied to the first landing sill 31 can be reduced. In addition, the car bottom 6 can be stably held horizontally, and the pair of first car guide rail brackets 4a can be easily positioned.

In addition, in the fifth positioning process, in the state where the car bottom 6 is lowered to the first landing floor, the pair of upper guide shoes 10 are respectively combined with the pair of car guide rails 2, and the pair of upper guide shoes 10 for positioning. Therefore, positioning of the pair of upper guide shoes 10 can be easily performed.

Furthermore, by assembling the car frame 7 corresponding to the positions of the pair of upper guide shoes 10, the assembly of the car frame 7 can be easily performed.

In addition, in the sixth positioning step, after raising the car bottom 6, the pair of car guide rails and the pair of upper guide shoes 10 are combined to position the pair of third car guide rail brackets 4c. Therefore, the positioning of the pair of third car guide rail brackets 4c can be easily performed.

Moreover, in the 2nd positioning process, a pair of counterweight rail 3 is combined with the rail positioner 22, respectively, and a pair of 1st counterweight rail bracket 5a is positioned. Therefore, positioning of a pair of 1st counterweight rail bracket 5a can be performed easily. Thereby, position adjustment of a pair of counterweight guide rail 3 can be performed easily.

Moreover, in the 4th positioning process, a pair of counterweight rail 3 and the rail positioner 22 are combined, and a pair of 2nd counterweight rail bracket 5b is positioned. Therefore, positioning of a pair of 2nd counterweight rail bracket 5b can be performed easily. Thereby, position adjustment of a pair of counterweight guide rail 3 can be performed easily.

Moreover, the car bottom connector 27 of Embodiment 1 has the hook part 27a and the sill receiving part 27b. Therefore, it is possible to more accurately position the car floor 6 with respect to the first landing sill 31 . Accordingly, the position of the pair of car guide rails 2 relative to the car floor 6 can be easily determined. That is, position adjustment of the pair of car guide rails 2 can be easily performed.

Moreover, since the insertion part 27c is provided in the hook part 27a, positioning of the car floor 6 with respect to the existing 1st landing sill 31 can be performed easily.

In addition, since the car sill 13 is received in the sill receiving portion 27b, the car bottom 6 and the first landing sill 31 can be easily connected.

Moreover, the guide rail positioning tool 22 of Embodiment 1 has the car bottom attachment part 22a and a pair of positioning parts 22b. Therefore, the position adjustment of a pair of counterweight guide rail 3 can be performed easily.

In addition, in the above example, the method of positioning and fixing the guide rail after connecting all the guide rail members was shown. However, after positioning and fixing one rail member, the positioning and fixing of the next rail member may be performed sequentially.

In addition, the landing-side end portion of the car bottom received by the car bottom receiving portion is not limited to the car sill.

In addition, the present invention can also be applied to elevators having three or more landing floors.

In addition, the first floor station floor is not limited to the lowest floor. In addition, the second floor station floor is not limited to the floor one floor above the first floor station floor.

In addition, the present invention can be applied to installation of newly installed elevators, and can also be applied to renovation of existing elevators.

In addition, the present invention can be applied to various types of elevators, such as an elevator having a machine room, a double-deck elevator, and an elevator of a single-shaft multi-car system. The single-shaft multi-car method is a method in which a plurality of cars independently move up and down in a shared shaft.
