Next, the working procedure of this embodiment will be explained.

First, guide rail CIA) flB) (2A) (
2B) Stand a single unit at the bottom of the hoistway. Then, on both sides of the suspension frame (23), rail suspension fittings (21
A) (Fix 21B1 with the seat plate (24), bolts (25) and nuts (26) at intervals that match the installation interval of the guide rail (IAI (IB) and guide rail + IA) flBl. At this time , seat board (24)
It serves to reinforce the hanging frame (23) and prevent the bolt (25) from rotating. Next, attach the hanging tool (
27) with the bolt (28) and the shackle (lO)
Hang winch robe (Ill) through.

Next, the member consisting of the rail suspension fittings [21A) (21B), the suspension frame (23), and the suspension tool (27) (hereinafter simply referred to as the suspension frame (23)) is moved from the bottom of the hoistway to the guide rail (l^1) on the top floor. (IB). Then, at that position, attach the rail suspension fittings (21Al F21
Connect the upper end of the guide rail (IAI (IBI) to the guide rail (IAI) (B). Next, after fastening the rail hanging hand [29A] F29B) to the rail hanging fittings (21A) (21B), attach the suspension frame (23) to the middle part. Guide rail (2^) F2B
), and then attach the upper end of the next guide rail to the lower end of the guide rail [2Al fzB] with a batten (3A).
Connect with (38).

In the same way, connect the guide rails one by one and raise the hoist until the rail hoist (29Al F29Bl) is at a position of about 500 mm from the bottom of the machine room floor (33), then remove the guide body (37A) [37B]. Rail fixing hole (36A1
F36B). And the rail handle (29A
+ Insert the fasteners (31A) (31B) of (29B) into the guide body [37Al F37B+ and guide them to prevent the rail handle f29A) F29B+ from colliding with the lower surface of the floor (33) of the machine room. Next, guide +37A)
(Remove 3781 and connect the sequentially connected guide rail into one through the rail fixing hole (36A) (fastener f31A) to the support plate (not shown) passed to 3681) (
Supported by 31Bl.

Next, from the bottom of the hoistway, use the centering piano wire f12Al.
Using F12B+ as a reference, center the guide rail using the rail 6 extension jig (13) and fasten it to the rail bracket (not shown) fixed to the hoistway, then loosen the nut (26) and attach the rail hanging bracket f21A. ) Remove the suspension frame (23) from F21B), loosen the bolt (22), and remove the guide rail.
(IA) (IB) to rail hanging bracket (21AI)
T21) Remove 1). At this time, since there is only one suspension frame (23), the nut (26) and bolt (22)
Loosening is easy. Note that at the same time as loosening the bolt (22), the bolt (30) is also loosened, and the fastener [31A
) f31B) and remove the rail hanging hand (29Al f
zzB+ will also be removed.

In addition, in the example, the rail hanging hand f29A) (298
) is the rail suspension fitting fzlA) (21B+), but the two may be formed integrally.

[Effects of the Invention] As explained above, in this invention, one side of the rail suspension metal fitting formed in a groove shape is connected to both sides of the suspension frame, the upper end of the guide rail is fastened to the rail suspension metal fitting, and the suspension frame is The lifting device was fixed to the center of the machine, connected to the lifting lobe, and the rail lifting hand supported on the machine room floor was fastened to the rail lifting fitting, so only one lifting frame was required, and the shape was simplified. As a result, the assembly and disassembly time at the installation site can be shortened, and the suspension frame does not interfere with the centering piano wire, making it possible to perform centering work using the rail 6 ejecting jig. Further, the guide rail is supported independently of the machine platform, and there is an effect that there are no restrictions on the procedure for installing the elevator.

In addition, in another invention of the present invention, a cylindrical guide body through which the rail lifting hand passes is inserted into the rail fixing hole in the floor of the machine room 1, so that the rail lifting hand does not collide with the lower surface of the machine room floor.
It is introduced into the machine room and has the effect of making it easier to support the guide rail in the machine room.
