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 suitable for efficiently installing elevator parts by reducing temporary materials.

[0002]

2. Description of the Related Art FIG. 4 is a flowchart for explaining a part of a conventional elevator installation method of this type, and FIG. 5 is a flowchart for explaining the remaining part of a conventional elevator installation method. 4 and FIG.
And it is continuous in each part of FIG.

Conventionally, elevator parts have been installed in accordance with the work procedures shown in FIGS. That is, first, as step a, an entrance curing sheet having a configuration as disclosed in, for example, Japanese Patent Application Laid-Open No. 7-257762 is provided at the entrance / exit of each floor to prevent accidents of people or objects from falling into the hoistway and to take safety measures. Then, as step b, lift the machine room equipment into the machine room, as step c, hang a piano wire in the hoistway to check the dimensions in the hoistway, and as step d, Center and fix the room equipment. Next, as a procedure e, the lowermost guide rails for the car and the counterweight are respectively erected, and as a procedure f, the car frame and the counterweight are respectively incorporated into the lowermost guide rail, and as a procedure g, the hoistway All the guide rails installed inside are connected to be unified, and the upper end of the integrated guide rail is connected to the machine room floor, and the lower end is connected to the lowermost guide rail and fixed. .

[0004] Next, as a procedure h, a wire rope is hung on the counterweight with the above-mentioned car frame, and as a procedure i, an upper portion of the car frame assembled in the hoistway is placed, for example, as disclosed in
A work floor and a protective ceiling made of temporary materials as described in JP-A-163282 and provided with safety fences around,
While the operator moves the car frame up and down on the work floor, the guide rail is centered and fixed in step j, and the doorway components are centered and fixed in step k. After the centering and fixing of the entrance / exit component is completed, the procedure l
Then, the curing sheet is removed from the hoistway entrance of each floor, and as step m, the operator gets on the work floor again, and performs mounting and wiring work of the equipment in the hoistway. Here, since the work floor is not required, the work floor is disassembled in step n of FIG. 5, the cab is mounted on the car frame in step o, and the test operation adjustment is performed in step p. Inspection and delivery are performed, and a series of operations are completed.

[0005]

By the way, in the above-mentioned conventional elevator installation method, since the work floor made of the temporary material is installed above the car frame, the work floor is disassembled after the installation work of the elevator parts is completed. And had to take it home. In addition, since the curing sheet and safety fence at the entrance and exit of the hoistway are also temporary materials, it is necessary to disassemble the temporary materials after completion of the above work and store them back home, which costs transportation and storage costs. There was also the problem of hanging.

As described in, for example, JP-A-64-64988, a permanent car floor is fixed to a temporary position above a car frame via a bracket and used as a work floor. There has also been proposed a method in which a car floor for permanent installation is re-installed from a temporary position to a proper position after the in-road equipment is installed. In this case, it is not necessary to install a work floor made of temporary materials on the upper part of the car frame.However, after using the permanent car floor as the work floor, the permanent There is a problem that it takes time and effort to re-install at the position.

The present invention has been made in view of such a situation in the prior art, and a first object of the present invention is to eliminate the need for installing a work floor made of a temporary material on an upper part of a car frame. An object of the present invention is to provide an elevator installation method capable of efficiently performing an elevator installation.

A second object of the present invention is to provide a method of installing an elevator which can prevent a falling accident of a person or an object without requiring provision of a temporary material such as a curing sheet or a safety fence at an entrance of a hoistway. Is to provide.

[0009]

In order to achieve the first object, the invention according to claim 1 of the present invention is directed to a method in which a car frame is installed in a hoistway by a permanent hoist installed in a machine room. In the elevator installation method in which the elevator frame is installed using this car frame, a plurality of guide rails are sequentially connected to the entire hoistway in order to unify the guide rails, A car frame composed of a vertical frame, a car ceiling, and a car floor is incorporated, and while the car frame is raised, the car floor of the car frame is used as a work floor, excluding the uppermost guide rail of the guide rails. Guide rails are centered and fixed to the hoistway, and equipment inside the hoistway arranged near these centered guide rails is installed, and then the car frame is formed in anticipation of the car side plate in the car frame. , The car Shitsujo as working floor, the is fixed to the hoistway to center the top guide rails, are a configuration installing the hoistway equipment arranged in the vicinity of the top guide rails.

In order to achieve the first object, the invention according to claim 2 of the present invention relates to the invention according to claim 1, wherein the plurality of guide rails are connected, and the vertical frame, the car ceiling and the car are connected. After installing the lower frame guide rail at the lower part of the hoistway and fixing it to the built-in car frame body composed of the floor, the car frame composed of the vertical frame, the car ceiling and the car floor is mounted on this lower guy rail. Then, a plurality of guide rails installed above the lowermost guide rail are sequentially connected to be unified, and the upper end of the unified guide rail is held on the floor of the machine room, The lower end of the integrated guide rail is connected to the lowermost guide rail.

According to the first aspect of the present invention having the above-mentioned structure,
In the invention according to the second aspect, after the worker gets into the car frame and performs the installation work in the lower part and the intermediate part of the hoistway, the worker gets into the car room mounted on the car frame. Since the installation work is performed in the upper part of the hoistway, the elevator can be efficiently installed without having to install a work floor made of a temporary material on the upper part of the car frame.

In order to achieve the second object, the invention according to claim 3 of the present invention is directed to the invention according to claim 2, wherein the lowermost guide rail is positioned at a landing on each floor before centering and fixing the guide rail. It has a configuration with an integrated doorway product.

In the present invention configured as described above, at the start of the installation work, by providing an entrance / exit unit at each landing entrance of each floor, it is not necessary to provide a temporary sheet such as a curing sheet or a safety fence at the entrance entrance. Furthermore, it is possible to prevent an accident in which a person or an object falls from the landing entrance into the hoistway.
