Abstract

PURPOSE:To provide a method for installing safely efficiently an elevator without providing a device for taking care of landing in an opening between a lift well and landing. CONSTITUTION:After a car device 8 or the like is carried into a lift well 1 by a crane 4, a landing doorway device 7 is carried into the lift well 1 by the crane 4 to attach the landing doorway device 7 to an opening 3. Thus, when the car device 8 is lowered in the lift well 1, the car device 8 does not make contact with the landing doorway device 7 while the car device 8 is easily carried in. Also, when the car device 8 is carried in, the opening 3 is not taken care of while an operation in the landing 2 is obliterated and an operation time in the lift well 1 is fairly short, so that a possibility of an object dropping from the opening 3 and hitting an operator in the lift well 1 is small. Thereafter, the opening 3 is covered by attaching a landing doorway device 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator installation method, and more particularly to an elevator installation method in which elevator components are sequentially loaded into a hoistway from above by a lifting device installed above the hoistway.

[0002]

2. Description of the Related Art Conventionally, as described in, for example, Japanese Patent Application Laid-Open No. 59-12064, a car device is provided in advance,
After assembling a landing entrance / exit device including a three-way frame and a door outside the hoistway, using a lifting device such as a crane, from the carry-in port provided at the top of the hoistway and the ceiling of the machine room to the car device, There has been proposed an elevator installation method in which a hall entrance / exit device and the like are carried into a hoistway and arranged at a predetermined position.

However, since there is a risk that a worker may fall down or an object may fall during the work from the opening formed between the hoistway and the landing on each floor, the work in the hoistway is started. Related laws and regulations stipulate that the safety of workers in landing halls and workers in hoistways will be ensured by curing the openings on each floor prior to.

Therefore, in the prior art, for example, Japanese Patent Laid-Open No. 14439/1990.
As described in Japanese Patent Publication No. 3, a reinforcing pipe is attached to the upper and lower portions of the curing sheet, and the reinforcing pipe is clamped and held by a clamp to facilitate the mounting and prevent the curing sheet from being damaged. An elevator elevator curing device was proposed. In this curing device, by covering the opening with a curing sheet, it is possible to prevent the worker from falling into the hoistway and the falling of objects, thereby ensuring the safety of the worker at the landing and the worker in the hoistway. It was supposed to be secured.

[0005]

By the way, in the above-mentioned conventional elevator hall curing device, after the temporary materials such as curing sheets and reinforcing pipes are transported to the installation site, or after the hall entrance / exit device is attached, the above-mentioned temporary materials are installed. However, there is a problem that it requires a lot of work time and labor because it is necessary to collect.

Instead of providing such a hall curing device, there is also a method of first providing a hall entrance / exit device to cover the hoistway and the opening between the halls and then carrying the car device into the hoistway. However, there is a concern that the car device may come into contact with the hall entrance / exit device when the car device is lowered in the hoistway. Therefore, there is a problem that it is considerably difficult to carry in the car device, and when the car device comes into contact, the hall entrance / exit device, which is a design product, is damaged.

The present invention has been made in view of the circumstances in the prior art as described above, and an object of the present invention is to provide a hall curing device at an opening formed between a hoistway and a hall. An object of the present invention is to provide an elevator installation method capable of safely and efficiently installing an elevator.

[0008]

In order to achieve this object, the present invention has a hoisting device installed above a hoistway and sequentially carries elevator parts into the hoistway from above by means of the hoisting device. In the installation method of the elevator, the step of loading the equipment in the hoistway including the pre-assembled car device into the hoistway by the lifting device at the time of factory shipment, and then the hoistway entrance / exit device that has been preassembled is lifted. Loading into the hoistway with a heavy device, and mounting the hall entrance / exit device to an opening formed between the hoistway and the hall, and curing the opening with the hall entrance / exit device. It is configured to

[0009]

As described above, according to the present invention, since the equipment in the hoistway including the car device is carried in prior to the carry-in of the hall entrance / exit device, when the car device is lowered in the hoistway, the hall It is not necessary to make contact with the entrance / exit device, the car device can be easily carried in, and the elevator can be efficiently installed.

Although the opening between the hoistway and the hall is not cured when the above equipment in the hoistway is carried in, there is no work at the hall at this time, and moreover, in the hoistway. Since the working time is quite short, the probability that an object will fall from the opening and hit the worker in the hoistway is quite small. After that, the hall entrance / exit device is attached to cover the opening. Therefore, it is possible to ensure the safety of the worker in the hoistway without specially requiring the hall curing device.
