Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an elevator hall door device assembled and unitized in a factory.

[Conventional technology]

Figures 3 and 4 show the Technical Report of the Invention Association (Official No. 84-0).
A front view and a cross-sectional view of a conventional elevator hall door device described in No. 04998, in which (1) is a hoistway wall, (2) is a hall opening, and (3) is a hall entrance ( Door stop side three-sided frame forming (4), (3a) is also the door pocket side three-sided frame, (5)
Is a hanger case fixed to the upper ends of the three-way frames (3) and (3a), (6) is a sill fixed to the lower ends of the three-way frames (3) and (3a), and (7) and (7a) are Two doors supported by the hanger case (5) and the threshold (6) to open and close the entrance (4), (8) is the hanger case (5) and doors (7), (7a) with bolts (9). Fixed mounting plate, (1
(0) is a mounting plate in which the sill (6) and the doors (7), (7a) are fixed with bolts (11), and (12) is an installation plate between the mounting plate (8) and the doors (7), (7a). It is the color worn.

The above hall door device is assembled and unitized at the factory, transported to the site, hoisted inside the elevator hoistway, temporarily fixed to the hall opening (2), and then as a safety measure for the entrance (4) Block (13).

[Problems to be solved by the invention]

Since the conventional hall door device is configured as described above, when installing the hall door device at the entrance (4),
A safety shelf (13) for falling prevention must be provided at the entrance / exit (4), which requires temporary materials, which requires construction time.

The present invention has been made in order to solve the above problems, and an object thereof is to obtain a landing door device capable of preventing a fall without using a safety shelf.

[Means for solving problems]

The hall door device according to the present invention is a unitized hall door device in which a stopper piece for temporarily fixing the hall door to the open state is detachably attached to the sill of the hall.

[Action]

The hall door device in this invention is to open the door when temporarily supporting the hall door device to the hall opening, and after the temporary support, remove the stopper piece and perform the installation work with the door closed. As a result, it is possible to prevent an operator from falling into the hoistway.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. First
In Fig. 2 and Fig. 2, (1) is a hoistway wall, (2) is a landing opening, (3) is a doorway side three-way frame, (3a) is a door pocket side three-way frame, (5)
Is a hanger case, (6) is a sill, and (7) and (7a) are two doors supported by the hanger case (5) and the sill (6) to open and close. It is the same as the conventional device shown. Reference numeral (14) is a hanging fitting which is bolted to the threshold (6) for lifting the unitized hall door device.
FIG. 2 is an enlarged sectional view taken along the line II-II of FIG. 1 showing a main part of the present invention. (14a) is a stopper piece, which is bolted to a sill (6) for lifting a landing door device. The metal fitting (14) is provided so as to face the end faces of the doors (7) and (7a) on the door closed end side. (15) is the door (7), (7a) of the stopper piece (14a)
And the door pocket side three-way frame (3a) and door (7),
It is a curing material that protects the surface of (7a).

In the hall door device configured as described above, the hanging metal fitting (14) is bolted to the sill (6) in the factory. As a result, the doors (7), (7a) are temporarily fixed by the stopper piece (14a) and assembled in an open state to be unitized. Then, the unitized hall door device is transported to the site, hung up in the hoistway, and temporarily supported in the hall opening (2) as in the case of FIG.

After that, prior to the installation work of the landing door device, the stopper piece (14a) was removed by removing the bolt connection and removing the hanging metal fitting (14) from the threshold (6), and the temporary door (7), (7a) was removed. Installation work of the hall door device is performed in a state in which the fixing is released and closed.

As a result, it is possible to prevent an accident such that the worker accidentally falls into the hoistway during the installation work.

[Effect of device]

INDUSTRIAL APPLICABILITY As described above, the present invention relates to an elevator hall door device in which a three-way frame forming an edge of a hall entrance, a hanger case, a sill, and a hall door are unitized. For this purpose, a hanging metal fitting that is detachably bolted to the sill is placed near the doorway side three-way frame at the entrance / exit of the hall, and the elevator door unit that is unitized and formed on this hanging fitting is installed in the landing opening. Sometimes, it is provided with a stopper piece for temporarily fixing the landing door in an open state.

As a result, when the unitized elevator hall door device is installed in the hall opening, the holder that serves only to temporarily fix the hall door in the open state is not required, and the manufacturing cost can be reduced. . Further, in the installation work of the door device, it is possible to prevent a fall accident without using a temporary material such as a conventional safety fence, and it is possible to shorten the installation work time.
