It comprises a main template 4 for closing a and a sub template 5 provided on the main template 4 and having both ends respectively arranged on the rope holes 3b, 3c. The main template 4 has a rope hole 4a located directly above a car (not shown), a rope hole 4b located directly above a counterweight (not shown), and a pair of holes located directly above the entrance / exit of the hoistway 1. Reference line pits 4c and 4d are provided. A pair of reference line pits 5a and 5b are also provided at both ends of the sub template 5, respectively. Examples of devices related to this type of device include those described in Japanese Utility Model Laid-Open No. 55-35205 and Japanese Patent Laid-Open No. 55-48182.

In such a conventional installation template, the elevator is installed according to the work procedure shown in the flowchart of FIG. That is, first, step S
As 1, the installation winch (not shown) is installed in the lower part of the hoistway 1 and the gold wheel is attached to the ceiling of the machine room 2.
Wrap the middle part of the winch rope around this gold wheel, insert the lifting hole 3a at one end side, hang down inside the hoistway 1 and wind it around the above installation winch, and also insert the lifting hole 3a at the other end side. Then, it hangs down in the hoistway 1. The other end of the winch rope is connected to the machine room equipment, for example, a control panel, and then the installation winch is operated to move the machine room equipment from the lower part of the hoistway 1 to the lifting hole 3a. Through the machine room 2
Similarly, other machine room equipment is sequentially lifted.
Then, as a step S2, the installation template is temporarily placed on the floor 3 of the machine room 2, and a reference line, for example, a piano wire is hung from the pits 4c and 4d into the hoistway 1. Is positioned on the floor 3 by moving the main template 4 back and forth on the floor 3 so as to match the reference positions on the reference floor (not shown). In step S4, the installation position of the machine room equipment is determined on the basis of the piano wire hanging from the pits 4c and 4d, and a base (not shown) for mounting the machine room equipment is placed on the floor 3. Fix it. Next, in step S5, the lowest rail member for the car and the lowest rail member for the counterweight (not shown) are centered and fixed to the wall portion of the hoistway 1, respectively, and in step S6, the winch rope is placed on the uppermost portion. By connecting and lifting the rail member and connecting a plurality of intermediate rail members under the uppermost rail member in sequence, the car guide rail and the counterweight guide rail are formed over the entire length of the hoistway 1. Then, each guide rail is held in a hoisted state in the hoistway 1, and a counterweight (not shown) is assembled under the hoistway 1 in step S7.
Assemble a platform (not shown) as 8, and perform step S9.
As a result, a wire rope (not shown) is wound around the hoisting machine. Next, in step S10, the above-mentioned lifted guide rails are centered and fixed to the wall of the hoistway 1 based on the piano wires hanging down from the pits 5a and 5b, respectively.

Among the above-mentioned operations, lifting of machine room equipment (procedure S1), lifting of guide rails (procedure S6), assembling a counterweight (procedure S7), assembling platform (procedure S8), and wire rope A winch for installation is used for winding (step S9).

[0007]

By the way, in general, when performing elevator installation, since the winch work using the installation winch is often outsourced from the elevator installation company to another company, a large number of elevator installations are performed at the same time. When it is performed, the outsourcing of the winch work tends to be concentrated. Therefore, it has been demanded to improve the setup of the winch work in order to smoothly install the elevator.

Then, in a series of operations using the above-mentioned conventional elevator installation template, steps S2 to S5 are performed between the lifting of the machine room equipment (step S1) and the lifting of the guide rails (step S6). Since the winch work is not required, the winch work is awaited during this period. Therefore, in order to reduce the waiting time for such winch work, first, the work that does not require the winch work, that is, the installation template is installed (step S2), and the bottom rail member is centered and fixed (step S5). After that, the machine room equipment that requires winch work is lifted (step S1), and then the work procedure is changed so that the machine room equipment is attached (step S4) and the guide rail is lifted (step S6). Can also be considered.

However, when the work procedure is changed as described above, the conventional installation template has only the pair of main installation rope holes 4a and 4b in the main template 4 that closes the lifting hole 3a. Therefore, the winch rope is stretched and the procedure S
After installing the installation template in 23, the winch rope and the installation template are removed when the machine room equipment is lifted. Therefore, the winch rope and the installation template are reattached. There was a problem that it took a lot of time and effort.

Also, for example, when assembling the counterweight in step S27, the winch-side portion of the winch rope hanging from the metal wheel of the ceiling of the machine room 2 is inserted into the rope hole 6a, and the tip portion is inserted into the other rope hole 6b. It is necessary to insert it in, and when assembling the platform in the subsequent step S28,
It is necessary to insert the tip portion of the winch rope into the rope hole 6a and insert the winch side portion into the other rope hole 6b. That is, since the winch rope removed from the above-mentioned gold wheel is exchanged from one rope hole to another rope hole during the lifting operation, the winch rope changing operation has occurred at least once. In this replacement work, first, connect another auxiliary rope to the end of the winch rope, lower the winch rope to the lower part of the hoistway 1, and then insert the tip of the auxiliary rope inserted into the other hole from the above gold car to the hoistway 1. Since the auxiliary rope and the winch rope are hung up to the lower part and the winch rope is wound up to the gold wheel and the winch rope is wound around the gold wheel again, there is a problem that it takes a lot of trouble.

The present invention has been made in view of the actual situation in the prior art as described above, and an object thereof is to allow the installation template to be attached and detached while the installation winch rope is stretched. It is an object of the present invention to provide an elevator installation template that can efficiently perform winch work without changing winch ropes.

[0012]

In order to achieve this object, the present invention provides a counterweight and a counterweight provided in the upper part of a hoistway and through which the upper end of a reference line stretched in the hoistway is inserted. In an elevator installation template having a pair of rope holes located directly above the car, respectively,
The winch rope wound around the installation winch at the lower part of the hoistway is provided with a notch portion through which the winch rope is inserted.

[0013]

Since the present invention is constructed as described above, the winch rope wound around the installation winch is inserted into the notch portion of the installation template provided in the upper part of the machine room and installed in the machine room, for example. The winch rope is wound around the metal wheel to be inserted into one of the rope holes of the installation template described above and hung in the hoistway. Then, when performing other work, after the tip side of the winch rope is wound up above the installation template by the operation of the installation winch,
It is adapted to be inserted into the other rope hole of the above-mentioned installation template and hang down in the hoistway. As a result, without having to change the installation winch rope,
The winch work can be performed efficiently. Further, since the winch rope is inserted through the cutout portion, the installation template can be attached / detached while the winch rope is stretched.
