[Detailed description of the invention] [Industrial application field] This invention relates to a rail fixing device installed in an elevator hoistway, and in particular to an improvement in the structure for mounting wall fittings on the uneven inner wall of the hoistway. It is.

[Conventional technology]

Figures 6 and 7 are, for example,
This shows a conventional elevator rail fixing device disclosed in Publication No. 152778. In the figure, 1 is an elevator hoistway, 1a is an inner wall surface of the hoistway, and 2 is a device that moves up and down in the hoistway 1 together with a counterweight 3. The cage is connected to a counterweight 3 via a rope (not shown). 4 and 4a are rails for guiding the car 2, 5 and 5a are rails for guiding the counterweight 3, 6 is an entrance door for the car 2, and 7

Reference numeral 8 designates fixing fittings for fixing the rails 4 and 5 to the inner wall surface 1a of the hoistway, including a wall fitting 9 made of angle iron and a rail fitting 10 formed by processing angle iron into a U-shape. are integrated by welding or the like during manufacturing, and are fixed to the inner wall surface 1a of the hoistway with anchor bolts 11. 8a and 8b are fixing fittings for fixing the rails 4a and 5b to the inner wall surface 1a of the hoistway, respectively; 12 is a fitting such as a clip for fixing the rails 4 and 5 to the vertical surface 10a of the rail fitting 10, etc. Usually, several dozen of the fixing fittings 8 are used per elevator in order to fix the rails 4 and 5 at intervals of 2 to 3 m over the entire height of the hoistway 1 of the elevator.

[Problem that the invention attempts to solve]

In the conventional elevator rail device as described above, it is assumed that the hoistway inner wall surface 1a is a flat vertical surface. Therefore, if the hoistway inner wall surface 1a has an uneven surface, the wall fittings 9 There is a problem in that the mounting pitch of the wall fittings 9 does not match and a large wall fitting 9 is required. Further, if the inner wall surface 1a of the hoistway is not a vertical surface, such as because it is bulged due to deformation, the wall fittings 9 must be fabricated by matching the actual wall fittings 9, which poses the problem of requiring a large amount of time for installation.

This invention was made in order to solve these problems, and aims to provide an elevator rail fixing device that has a simple structure, can greatly simplify the rail installation work, and can provide sufficient rail fixing force. purpose.

[Means for solving problems]

The elevator rail fixing device according to this invention includes a spacing member disposed on the concave surface of the hoistway inner wall between the wall fitting fixed to the hoistway inner wall of the elevator and the hoistway inner wall. This is how it was done.

[Effect]

In this design, a spacer is interposed between the wall fittings and the inner wall of the hoistway, so even if the inner wall of the hoistway has an uneven shape, the wall fittings can be firmly fixed without any problem. In addition, by mounting the wall fittings floating from the inner wall surface of the hoistway using the spacer, it is possible to prevent the wall fittings from becoming unable to be attached to the inner wall surface of the hoistway due to deformation of the inner wall surface of the hoistway.

〔Example〕

1 and 2 show an embodiment of this invention, and in the figures, the same reference numerals as in FIGS. 6 and 7 indicate the same or corresponding parts. 13 is a deck plate stretched on the inner wall surface 1a of the hoistway, 13a is a concave surface of this deck plate 13, 13a is a similar convex surface, and 14 is an intervening surface between the concave surface 13a and the vertical mounting surface 9a of the wall fitting 9. The block material is fixed to the deck plate 13 together with the wall fittings 9 using anchor bolts 11 or insert screws embedded in the inner wall surface 1a of the hoistway. H is the mounting surface 9 of the wall fitting 9 made of the block material 14.
a and the convex surface 13b of the deck plate 13.

In the elevator rail fixing device configured as described above, first, a block material 14 is placed between the concave surface 13a of the deck plate 13 stretched on the inner wall surface 1a of the hoistway and the vertical mounting surface 9a of the wall fitting 9. Insert the anchor bolt 11 or hoistway inner wall surface 1
Fix it with the insert screw buried in a.
As a result, a gap H is formed between the convex surface 13b of the deck plate 13 and the mounting surface 9a of the wall fitting 9, as shown in FIG. Even if deformation occurs, the wall fitting 9 can be installed while avoiding this deformation. Therefore, there is no problem with centering work, etc., which will be described later.

After the wall fitting 9 is fixed in this way, the rail 4 is fixed to the vertical surface 10a of the rail fitting 10 using the fixture 12, and the rail 4 is centered. The fixing fitting 8 is formed by integrating the fitting 10 with the fitting 10 by welding or the like.

Therefore, using the block material 14, the convex surface 13b of the deck plate 13 and the mounting surface 9a of the wall fitting 9 are connected.
By forming a gap 〓H between them, even if the inner wall surface 1a of the hoistway has an uneven shape, there is no need to increase the size of the wall fittings 9 or to process them by matching the actual parts. It becomes possible to fix the wall fitting 9.

Figure 3 shows another embodiment of this invention.
A cushioning material 15 is used in place of the block material 14 in the above embodiment. This third
According to the figure, vibrations generated from the counterweight 3, the car 2, etc. can be prevented from being transmitted to the building, and the living environment of the building can be improved.

FIG. 4 shows still another embodiment of this invention, in which a cushioning material 16 is passed between the convex surfaces 13b of the deck plate 13, a wall fitting 9 is arranged, and the anchor bolt 1 is
It is designed to be tightened at step 1. According to FIG. 4, the same effects as in FIG. 3 can be expected with a simple structure.

FIG. 5 shows still another embodiment of this invention, which is applied when the wall fitting 9 must be installed across the convex surface 13b and concave surface 13a of the deck plate 13 due to the layout of the hoistway 1. It is something that That is, the cushioning material 16 is interposed between the convex surface 13b of the deck plate 13 and the wall fitting 9, and the concave surface 13a of the deck plate 13
A block material 14 is placed in the block material 14, and a spacer 17 having a U-shaped notch at one end is interposed between the block material 14 and the buffer material 16 to adjust the height of the block material 14. It is something. According to this FIG. 5, the wall fittings 9 are attached to the deck plate 1.
3, the same effect as shown in FIG. 3 can be expected no matter where it is installed.

[Effect of idea]

As explained above, this idea is arranged between the wall fitting fixed to the inner wall of the elevator hoistway and the inner wall of the hoistway, one side being placed on the concave surface of the inner wall of the hoistway and the other side being placed on the convex surface of the inner wall of the hoistway. Since the spacing material is interposed to protrude more than the
Even if the inner wall of the hoistway has an uneven shape,
To firmly fix a wall fitting without enlarging the wall fitting or performing processing to match the actual wall fitting.
