Abstract

PURPOSE:To install device in an extension elevation passage above a unit during temporary operation of a cage in the elevation passage below the unit by mounting a template for a centering work on the upper edge part of a machine room unit and stretching piano wires for a centering work below and above the unit through the template. CONSTITUTION:A template 10 for a centering work is secured to an upper beam 4c of a machine room unit 4. The template 10 comprises a template 10a for a floor platform, a template 10b for a cage rail, and a template 10c for a balance weight. A piano wire 9 for centering is stretched from each of the templates 10a-10c, and a piano wire 11 for centering is extended to above and stretched between the template and a fixing body at the topmost end of an elevation passage 2. A unit 4 is temporarily installed, a device is installed in a underlaying elevation passage 2 through the piano wire 9 and temporarily operated. When the elevation passage 2 is extended upward, a device is installed in an extension elevation passage 2 through the piano wire 11 in a state to continue temporary operation. This method increases the efficiency of a device installing work.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elevator installation method in which a temporarily installed machine room unit is gradually raised to perform the installation work as building construction progresses.

[Conventional technology]

3 and 4 are diagrams showing a conventional elevator installation method disclosed in, for example, Japanese Unexamined Patent Publication No. 48-63451, and in FIG. 9, (1) shows a building under construction.

(2) is a hoistway that is built inside building (1) and gradually extends upward; (3) is a beam that is temporarily installed at the top of the hoistway (2); (4) is a hoistway that is The machine room unit is supported by a beam (3) and is configured as follows. In other words, the floor beam (
4a), a cross beam (4b), and a top beam (4C).
d), a hoisting member (4e) is provided on the floor beam (4a), and a control panel (4f) is provided on the cross beam (4b). (5) is a car wrapped around the hoisting machine (4e) and suspended from the main rope (6), and (7) is a rail installed below the machine room unit (4) of the hoistway (2). , (8) is a shape board for centering work, fixed on the floor beam (4a), (
8a) is the landing board circumferential plate, (8b) is the car rail circumferential plate,
(8c) is a counterweight rail peripheral plate. (9)
are centering piano wires suspended from the shape plates (8a) to (8c), respectively.

In conventional elevator installation, the components are arranged as described above, and the car (5) is carried by a tower crane (not shown) and the machine room unit (4) is carried into the hoistway (2) under construction. It will be temporarily installed near the upper end of the hoistway (2). Then, the piano wire (9) suspended from the shape board (8)
) The equipment in the hoistway (2) such as the rail (4) is installed. Next, the machine room unit (4) moves the car (5
) will be put into temporary operation for construction work. In addition, as the construction of the building progresses, a hoistway (
When 2) is extended, the 7 machine room unit (4) is moved upward.

Equipment in the extended hoistway (2) was installed.

A temporary operation including the extension of the car (5) will be carried out.

[Problem to be solved by the invention]

In the conventional elevator installation method as described above.

Since the piano wire (9) is stretched from the shape plate (8) of the floor beam (4a) of the machine room unit (4), one machine room unit (4)
) It is difficult to tension the centering piano wire for the extension of the hoistway (2) constructed successively above the hoistway (2).

Therefore, after raising the machine room unit (4) to correspond to the extended hoistway (2), the piano wire (9) is stretched and the equipment in the hoistway (2) is installed.

For this reason, there was a problem in that the temporary operation suspension period of the car (5) becomes long.

This invention was made in order to solve such problems, and the object is to obtain an elevator installation method that allows equipment in the hoistway to be installed in the hoistway for an extension above one machine room unit. It is said that

[Means to solve the problem]

In the elevator installation method related to this invention, 1
A shape plate for centering work is attached to the upper edge of the machine room unit, and piano wires for centering work are stretched below and above the machine room unit via this shape plate.

[Effect]

In the elevator installation method described above, it is possible to install equipment in the hoistway extending above the 9th machine room unit during temporary operation of the car below the 1st machine room unit.

〔Example〕

FIGS. 1 and 2 are diagrams showing an embodiment of the present invention. In FIG. 1, the same reference numerals as in FIGS. 3 and 4 indicate corresponding parts.
10) is a shape plate for centering work and has 9 machine room units (4)
It is fixed to the upper beam (4c), (10a) is the landing layer plate, (10b) is the car rail layer plate, and (10c) is the counterweight circumferential plate. (9) is the shape plate (10
) The piano wire for centering is stretched from below.

(11) are each extended upwardly from the profile plate (10).

This is an upper piano wire for centering the hoistway (2-in extension) stretched between the hoistway (2) and a fixed body (not shown) at the top end.

In the elevator installation method configured as described above, one machine room unit (4) is temporarily installed, and the hoistway (2) below the machine room unit (4) is installed via the piano wire (9).
Internal equipment will be installed. Due to this.

The car (5) is temporarily operated below the machine room unit (4). Then, a hoistway (2) is constructed and extended above the first machine room unit (4).

With the upper piano wire (11) being stretched and the car (5) temporarily operating, equipment in the extended hoistway (2) is installed. Then, when the equipment installation in the extended hoistway (2) is completed, the first machine room unit (4) is moved upward, and the temporary operation of the car (5) including the extended hoistway (2) is resumed. Therefore, the temporary operation suspension period of the car (5) can be shortened, and the car (5) can be efficiently used for construction work. Also, the shape plate (10) is connected to the lower piano wire (9).
) and the upper piano wire (11), only -times of positioning is required, making the installation work more efficient.

〔Effect of the invention〕

As explained above, this invention involves attaching a shape plate for centering work to the upper edge of a machine room unit that is temporarily installed near the upper end of a hoistway that is being constructed, and aligning the lower and upper parts of the machine room unit. The work piano wire is stretched, making it possible to install equipment in the extended hoistway above the machine room unit during temporary operation of the car below the machine room unit. Therefore, by moving the machine room unit upward after the equipment installation in the extended hoistway is completed, it is possible to shorten the temporary operation interruption period of the car, which has the effect of streamlining the use of the car for construction work.
