DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator installation scaffolding device suitable as a scaffold for various operations performed in a hoistway.

[0002]

2. Description of the Related Art As a conventional scaffolding device for installing an elevator, there is a configuration shown in Japanese Utility Model Publication No. Hei 7-26303, which will be described with reference to FIG.

As shown in FIG. 3, as a method for adjusting the position of the horizontal member 5, a telescopic member 1 having holes 20 provided at both ends of the base member 2 and provided at minute intervals is used.
The telescopic member 1 is fixed to the base member 2 with a fixing member such as a pin (not shown) at an arbitrary position, and the depth of the hoistway from the hall opening 3 to the hoistway wall 4 opposed to the hall opening 3 The length of the horizontal member 5 was determined according to the dimensions.

Further, the position of the inclined member 6 is adjusted by adjusting the length of the base member 6 so that the length of the horizontal member 5 is equal to the length of the horizontal member 5 to be determined.
b was expanded and contracted to adjust its dimensions.

[0005]

However, the conventional scaffolding device for installation has a problem that the dimensional adjustment work is complicated and the working efficiency is deteriorated.

In other words, the position adjustment of the conventional horizontal member 5 has to be repeated several times in order to adjust the depth dimension of the hoistway and the length of the horizontal member. In addition, the work had to be adjusted, and the work was complicated and the work efficiency was deteriorated.

Further, every time the position of the horizontal member 5 is changed, the inclination member 6 must be expanded and contracted, so that the work efficiency is further reduced.

Furthermore, in the conventional scaffolding device, it is necessary to provide a large number of position adjusting holes 20 at minute intervals so that the position can be adjusted at minute intervals, so that the elastic members 1 and 6a are weak in strength. There was a problem.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an elevator installation scaffolding apparatus which can be easily installed in accordance with an elevator model.

[0010]

In order to achieve the above object, the present invention provides a vertical member erected between upper and lower walls of a landing opening of an elevator, and a hoistway connected to the vertical member and extending from the landing opening. An elevator installation scaffolding device comprising: a horizontal member extending substantially horizontally inward, and an inclined member having one end connected to the horizontal member and the other end connected to a lower portion of the vertical member. It has a first horizontal member having a first telescopic unit that can be extended and contracted at a predetermined interval set corresponding to each model, and a second elastic unit that can be extended and contracted at a minute interval at least from the predetermined interval. The horizontal member is formed from the second horizontal member, and a third expansion / contraction means is provided to make the inclined member expandable / contractible at a predetermined interval set for each elevator model.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 are side views of an elevator installation scaffolding apparatus showing one embodiment of the present invention.

First, the configuration of the scaffold device 10 for installing an elevator according to the present embodiment will be described. The same reference numerals as those used in the description of the related art indicate the same components.

In the figure, a horizontal member 5 is a base member 2
A stopper 1a having a thread portion whose length can be adjusted steplessly at the end on the hoistway wall 4 side and a second hole 20 provided at a minute interval at the same time as the stopper 1a at the end on the hoistway wall 4 side And a first elastic member 11 having holes 21 provided at predetermined ends of the base member 2 on the side of the landing opening 3 at predetermined intervals corresponding to the types of elevators.
The horizontal member 5 is fixed by a clamp 14 near an intermediate portion of a vertical member 13 installed vertically to the hall opening 3, and the vertical member 13 has a thread portion having an adjustable length at its upper end. The length can be freely adjusted by a telescopic member 13a having holes provided at small intervals at the same time as having a stopper 13b having a stopper 13b.

At the lower end of the vertical member 13, there is provided a third telescopic member 12 having holes 22 provided at predetermined intervals corresponding to the types of elevators as the telescopic mechanism of the inclined member 6. It is attached so as to be rotatable, and the inclined member 6
Is fixed to a predetermined position of the base member 2 of the horizontal member 5 by a clamp 15 so as to be rotatable.

Further, on the base member 2 of the horizontal member 5,
A work floor 17 having a handrail 18 is provided.

The elevator installation scaffolding apparatus 10 configured as described above adjusts the second telescopic member 1 of the horizontal member 5 in accordance with the hoistway depth dimension, and at the same time, presets it in accordance with the elevator model. The first elastic member 11 is adjusted using the predetermined hole 21 which has been
Is determined by adjusting the length of the third telescopic member 12 using a predetermined hole 22 preset according to the model of the elevator, whereby the inclined member 6 is connected to the horizontal member 5. The position of the clamp 15 is automatically determined to a preset mounting position.

When the elevator model is larger than that of FIG. 1, as shown in FIG. 2, the first telescopic member 11 and the third telescopic member 12 are fixed at a predetermined length. By changing the positions of the holes 21 and 22 to predetermined positions and using them, the first and third elastic members 11 and 12 can be used.
Can be determined to be an appropriate length, and the position of the clamp 15 which is a connecting portion of the inclined member 6 with the horizontal member 5 is automatically determined to a preset mounting position.

In addition, even if the elevator model is the same,
If the hoistway depth dimension, which cannot be specified depending on the elevator model, changes, the first and third telescopic members 11,
By adjusting the lengths of the second telescopic members 1 and 1a without changing the length of the clamp 12, the position of the clamp 15, which is the connecting portion of the inclined member 6 with the horizontal member 5, is set in advance. The position is automatically determined, and the work floor 17 can be set to a position suitable for the type of the elevator to be installed.

In this way, the position of the base member 2 of the horizontal member 5 on which the work floor is mounted can be set at a predetermined position from the landing opening 3 depending on the type of elevator, regardless of the depth dimension of the hoistway. The optimal position for installation can be automatically determined.

The first and third elastic members 11, 12
Since the number of holes 21 and 22 provided in the frame is limited to the required number and the number of holes can be reduced, the strength of the elastic members 11 and 12 can be sufficiently secured, and safety can be improved.

As described above, according to the present embodiment, it is possible to adjust the depth of the hoistway and the model of the elevator without changing the length of the horizontal member and the inclined member repeatedly without repeatedly positioning them. The work floor can be easily installed.

[0023]

As described above, according to the present invention, it is possible to provide an elevator installation scaffolding apparatus which can be easily installed in accordance with an elevator model.
