DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. Embodiment 1 FIG. 1 is a side view showing an elevator rail bracket device according to Embodiment 1 of the present invention, FIG. 2 is a perspective view showing a main part of FIG. 1, FIG. 3 is a front view of FIG. 1, and FIG. It is sectional drawing which follows the IV line. In the figure,
A vertically extending column 1 is fixed between the building beams on the upper and lower floors facing the hoistway. A metal wall bracket 2 having an L-shaped cross section is fixed to the upright 1.

An L-shaped rail-side bracket 3 made of metal is fixed to the wall-side bracket 2. The rail-side bracket 3 extends parallel to the back surface 4a of the guide rail 4 and has one end (the upper end in FIG.
And a fixing portion 3b provided at the other end (the lower end in FIG. 1) of the vertical portion 3a and fixed to the wall-side bracket 2.

A spacer 5 is interposed between one end of the vertical portion 3a and the back surface 4a of the guide rail 4, so that a gap 6 is formed between the vertical portion 3a and the back surface 4a. . One end of the vertical portion 3a is connected to the guide rail 4 via a rail clip (not shown).

In such a rail bracket device, the rail-side bracket 3 is connected to the guide rail 4 only at one end of the vertical portion 3a, and a gap 6 exists between the vertical portion 3a and the guide rail 4. Therefore, the rigidity of the rail side bracket 3 is appropriately reduced, and the vertical portion 3a can be slightly elastically deformed. For this reason, the vibration of the guide rail 4 is absorbed by the vertical portion 3a, and the guide rail 4 is used without using a special member such as an elastic body or a vibration absorbing member.
The transmission of the vibrations to the upright 1 is suppressed.

The rigidity of the rail-side bracket 3 is
It is adjusted by changing the length and thickness of a, but if it is too low, sufficient support strength will not be obtained,
The adjustment is made in consideration of this point. The rigidity of the rail side bracket 3 is designed to be as small as possible within a range substantially equal to or greater than the rail rigidity. Thereby, even if there is an initial bend of the guide rail 4 at the time of rail installation, by fixing the guide rail 4 to the rail-side bracket 3, it is possible to obtain a supporting strength that can correct the initial bend.

In the case of a flexible hoistway in which the uprights 1 are fixed between the building beams of the building, it is necessary to directly weld and fix the wall-side brackets 2 to the uprights 1. A fixing method such as bolt fixing that can sandwich a spacer cannot be adopted. On the other hand, Embodiment 1
As shown in the above, if the spacer 5 is arranged between the back surface 4a of the guide rail 4 and the rail-side bracket 3, it is possible to prevent the vibration of the guide rail 4 from being transmitted to the building side even in a flexible hoistway. Can be suppressed.

Further, even when the wall-side bracket is fixed to the hoistway wall, the back surface 4a of the guide rail 4 is processed with higher precision than when a gap is formed between the wall bracket and the hoistway wall, which is relatively rough. Therefore, the gap 6 can be secured with high accuracy.

In the first embodiment, the wall-side bracket 2 is fixed to a single upright 1, but a wall-side bracket serving also as an intermediate beam may be horizontally fixed between a pair of vertically extending uprights.

Embodiment 2 In the first embodiment,
Although the rail-side bracket 3 is arranged so that the vertical portion 3a extends upward from the fixing portion 3b, as shown in FIG. 5, it may be arranged so that the vertical portion 3a extends downward from the fixing portion 3b.

Embodiment 3 FIG. Further, Embodiments 1 and 2
In the embodiment, the fixing portion 3b of the rail side bracket 3 is fixed to the wall side bracket 2, but the fixing portion 3b may be fixed to a base plate 8 fixed to a building beam 7 of a building, for example, as shown in FIG. In such a structure, since the rail-side bracket 3 is directly welded to the base plate 8, it is difficult to form the gap 6 between the rail-side bracket 3 and the base plate 8.
If it is between a and the vertical portion 3a, the necessary gap 6 can be secured more accurately.

Embodiment 4 Next, FIG. 7 is a side view showing an elevator rail bracket device according to Embodiment 4 of the present invention. In the drawing, a support base 9 is fixed on a base plate 8 by welding. A vertical surface 9 extending parallel to the back surface 4a of the guide rail 4 is provided on the support base 9.
a is provided.

The support base 9 is connected to the L through a mounting bolt 10.
The support-side bracket 11 having a letter shape is fixed. An L-shaped rail-side bracket 12 is welded and fixed to the support base-side bracket 11. The rail bracket 13 according to the fourth embodiment includes the support-side bracket 11 and the rail-side bracket 12.

The support base side bracket 11 has a vertical portion 13a extending parallel to a vertical surface.
One end (lower end) of “a” is fixed to the support base 9. The rail-side bracket 12 has a connection portion 13b joined to the back surface 4a of the guide rail 4 and connected to the guide rail 4 via a rail clip (not shown).

A spacer 15 is formed between one end of the vertical portion 13a and the vertical surface 9a of the support 9 to form a gap 14 between the vertical portion 13a and the vertical surface 9a. The rail bracket device according to the fourth embodiment includes a support 9, a mounting bolt 10, a rail bracket 13, and a spacer 15.

In such a rail bracket device, since the gap 14 is formed between the highly rigid support base 9 and the rail bracket 13, the guide 14 can be used without using a special member such as an elastic body or a vibration absorbing member. The transmission of the vibration of the rail 4 to the building beam 7 is suppressed. Further, by fixing the support base 9 having the vertical surface 9a to the base plate 8, the spacer 15 can be arranged not on the guide rail 4 side but on the base plate 8 side.

Although the support base 9 is fixed to the base plate 8 in the fourth embodiment, it may be fixed to another member as long as it can be fixed to a building beam.

Embodiment 5 FIG. Next, FIG. 8 is a side view showing an elevator rail bracket device according to Embodiment 5 of the present invention. In the figure, a metal support base 16 having a U-shaped cross section is fixed on a base plate 8. The support base 16 includes a horizontal base fixing portion 16a fixed to the base plate 16, a bracket fixing portion 16b parallel to the base fixing portion 16a, a base fixing portion 16a extending parallel to the guide rail 4, and a base fixing portion 16b. And a vertical plate portion 16c to be connected.

have.

In such a rail bracket device, by adjusting the rigidity according to the plate thickness and the height dimension of the vertical plate portion 16c, it is possible to adjust the vibration transmission characteristics and the support strength to the optimum state. Thereby, the transmission of the vibration of the guide rail 4 to the building beam 7 side is suppressed without using a special member such as an elastic body or a vibration absorbing member. In addition, even when the distance between the hoistway wall and the guide rail 4 is relatively small, the support base 16 can be arranged to reduce the transmission of vibration.

Embodiment 6 FIG. In the fifth embodiment,
Although the support base 16 is arranged so that the rail bracket 17 is located above the base plate 8, for example, as shown in FIG.
The support 16 may be arranged so that 7 is located.

Further, in the fifth embodiment, the support base 16 is fixed to the base plate 8, but may be fixed to another member as long as it can be fixed to a building beam.

Embodiment 7 Next, FIG. 10 is a side view showing an elevator rail bracket device according to a seventh embodiment of the present invention, and FIG. 11 is a sectional view taken along the line VIII-VIII in FIG. In the figure, on the shaft wall 20,
An L-shaped wall-side bracket 22 is fixed by a plurality of anchor bolts 21. L on the wall side bracket 22
A rail-shaped bracket 23 in the shape of a letter is fixed. The rail bracket 24 according to the seventh embodiment includes the wall bracket 2.
2 and a rail-side bracket 23.

The wall side bracket 22 has a vertical portion 24 a extending parallel to the guide rail 4, and one end (lower end) of the vertical portion 24 a is fixed to the hoistway wall 20. The rail-side bracket 23 is joined to the back surface 4a of the guide rail 4 and has a connection portion 24b connected to the guide rail 4 via a rail clip (not shown).

Between one end of the vertical portion 24a and the hoistway wall 20, there is a gap 25 between the vertical portion 24a and the hoistway wall 20.
Is interposed. A plurality of backing plates 27 are fixed to the vertical portion 24a. The backing plate 27 is provided with a screw hole, and an adjusting bolt 28 is screwed into the screw hole. The tip of the adjusting bolt 28 penetrates the vertical portion 24a and protrudes into the gap 25.

The amount of adjustment bolt 28 projecting toward the hoistway wall 20 is adjusted by the amount of screwing. The amount of deformation of the vertical portion 24a toward the hoistway wall 20 is regulated according to the distance between the tip of the adjustment bolt 28 and the hoistway wall 20.
The adjusting bolt 28 is screwed with a double nut 29 for preventing loosening. The deformation restricting means 30 according to the seventh embodiment includes a backing plate 27, an adjustment bolt 28, and a double nut 29. The rail bracket device includes an anchor bolt 21, a rail bracket 24, a main spacer 26, and a deformation restricting means 30.

In such a rail bracket device, since the gap 25 is formed between the hoistway wall 20 and the vertical portion 24a, the guide rail 4 can be used without using a special member such as an elastic body or a vibration absorbing member. Of the vibration of the building is transmitted to the building beam 7 side. Further, since the amount of deformation of the vertical portion 24a is regulated by the adjustment bolt 28, when a large load due to an earthquake or the like acts on the hoistway wall 20, a stress exceeding an allowable value is generated in the rail bracket 24. Can be prevented.

Furthermore, since the surface of the hoistway wall 20 is generally roughened, the size of the gap 25 is set to, for example, 1 to 1.
Although it is difficult to set the gap to 2 mm, in the seventh embodiment, the gap 25 is set slightly larger, and the substantial gap dimension can be defined by the amount of tightening of the adjustment bolt 28, so that the surface of the hoistway wall 20 is accurate. Even when the rail bracket 24 is not flat, the amount of deformation of the rail bracket 24 can be more accurately regulated.

Furthermore, since the rail bracket 24 has a relatively small plate thickness, it is often not possible to secure a sufficient length of the screwing portion of the adjusting bolt 28. The length of the hole can be sufficiently ensured.

In the seventh embodiment, two adjustment bolts 28 are used. However, even if only one adjustment bolt 28 is used,
There may be three or more. Further, the number of the contact plates 27 can be changed according to the number of the adjustment bolts 28.

Further, as compared with the case where the adjustment bolt 28 shown in the seventh embodiment is used, the configuration can be simplified and the cost can be reduced.

In the eighth embodiment, the adjusting spacer 3
Although 1 is attached to the wall-side bracket 22 by the bolt and nut 32, it may be attached by an adhesive or welding. Further, it may be attached using a clip, a rope, a wire, or the like.

Embodiment 9 FIG. Next, FIG. 13 is a side view showing a mounting state of an adjusting spacer according to Embodiment 9 of the present invention, and FIG. 14 is a front view showing a mounting state of the adjusting spacer of FIG. In the figure, the vertical portion 24a and the hoistway wall 20
Between them, a plurality of adjustment spacers 34 as deformation restricting means are stacked and arranged.

At the lower ends at both ends in the width direction of each adjustment spacer 34, there are provided legs 34a which engage with both ends of the main spacer 26. The adjustment spacer 34 disposed on the side closest to the hoistway wall 20 has a vertical portion 24a
An engagement portion 34b is provided to bend so as to embrace.

Even when such an adjusting spacer 34 is used, the amount of deformation of the vertical portion 24a can be regulated more accurately with a simple configuration.

Embodiment 10 FIG. Next, FIG. 15 is a front view showing a mounting state of an adjustment spacer according to Embodiment 10 of the present invention. In the figure, a leg 35 a is provided at the lower end of the adjustment spacer 35. The main spacer 26 is provided with a recess 26a into which the leg 35a is inserted. The adjusting spacer 35 is provided with an engaging portion 35b which is bent so as to embrace the vertical portion 24a at the time of mounting.

In the ninth and tenth embodiments, the vertical portion 2
FIG. 1 shows the engagement portions 34b and 35b that embrace the 4a.
An engaging portion may be provided on the horizontal portion of the L-shaped adjustment spacer as shown in FIG. 2 so as to embrace the horizontal portion of the wall-side bracket 22.

Embodiment 11 FIG. Next, FIG. 16 is a front view showing an attached state of an adjustment spacer according to Embodiment 11 of the present invention.

Here, the wall-side bracket 2 against the force Py
The simplest method for increasing the torsional strength of No. 2 is to increase the thickness of the wall-side bracket 22 itself.
If the plate thickness is simply increased, bending of the wall-side bracket 22 becomes difficult, or rigidity against a force Px in a direction perpendicular to the hoistway wall 20 becomes unnecessarily high. Problems such as easy transmission of vibrations may occur.

On the other hand, in the twelfth embodiment, the reinforcing plate 41 is joined only to the vertical portion 24a, and particularly the force Px
In this case, the movement of the wall-side bracket 22 is not restricted, so that the above-described problem does not occur, and the torsional strength can be effectively increased. That is, since the reinforcing plate 41 has a sufficient size to cover the vertical portion of the wall-side bracket 22, the reinforcing plate 41 cannot be deformed in a direction in which the wall-side bracket 22 moves away from the shaft wall 20. 41 regulates the movement of the wall-side bracket 22, and the torsional strength can be increased.

In the twelfth embodiment, one reinforcing plate 4
However, for example, two reinforcing plates may be attached to the left and right anchor bolts 21, respectively. Further, a plurality of reinforcing plates may be stacked and attached. Furthermore, the method of attaching the reinforcing plate to the wall-side bracket 22 is not limited to the twelfth embodiment. For example, a dedicated attachment bolt may be used.

Further, the shapes of the rail-side bracket, the wall-side bracket and the rail bracket are not limited to the L-shape, and may be, for example, a gate shape, a trapezoidal shape, or a combination of a plurality of L-shaped angle members. .
