DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator hall display device provided between a three-way frame of an elevator hall and a building wall.

[0002]

2. Description of the Related Art In general, a three-way frame formed of a vertical frame and a horizontal frame and a display device case are attached to an elevator hall, and these are installed in holes that pass through a hoistway of a building wall and open. .

First, a conventional elevator hall display device will be described with reference to FIGS. In the drawing, 1 is a building wall, 2 is a three-way frame installed at an elevator opening, 3 is a reinforcing bar projecting from the building wall 1, 4 is a mounting metal bolted (not shown) to the three-way frame 2, and 5 is a reinforcing bar. 3 is a reinforcing bar that connects the mounting metal 3 and the mounting metal 4 to fix the three-way frame 2.

Reference numeral 6 denotes a weir plate, which is positioned and fixed to the building wall 1 with concrete nails (not shown) so as to close a gap between the building wall 1 and the three-sided frame 2 from one side. In addition, since the weir plate 6 is usually made of a steel plate, there is no problem in the fire prevention regulations even if it is left as it is. 7 is a mortar packed in a gap between the building wall 1 and the three-sided frame 2, 8 is a mounting metal 4 and a display attached to the reinforcing bar 3 buried in the building wall 1 and installed on the side of the three-sided frame 2. The case 8 is a device case (hereinafter, abbreviated as a case).

[0005] In the conventional landing display device configured as described above, first, the weir plate 6 for stopping the mortar 7 is attached to the hoistway side of the gap between the building wall 1 and the three-way frame 2. Also,
The case 8 is attached to the attachment 4 and the reinforcing bar 3. Next, the mortar 7 is gradually packed from the lower part to the upper part of the gap between the building wall 1 and the three-way frame 2. Thereafter, a finishing wall 9 as a wall material is applied to the surface of the mortar 7.

[0006]

In the above-described conventional landing display device, even if the mortar 7 is packed little by little from the lower part of the gap, the mortar 7 is packed from the middle part to the upper part by the weight of the mortar 7 itself. In some cases, the mortar 7 collapsed and required rework. Also, in the situation after the mortar 7 is packed, the weight of the mortar 7 similarly becomes non-uniform due to the weight of the mortar 7, resulting in poor quality and often requiring rework. Therefore, there has been a problem that the installation work of the conventional hall display device requires a lot of time.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide an elevator hall display device capable of shortening the time required for installation work.

[0008]

According to a first aspect of the present invention, there is provided an elevator hall display device having a display device damping plate having a shape punched into a size of a display device case and holding the display device case with punched pieces. , Provided between the three-way frame and the building wall.

According to a second aspect of the present invention, there is provided a landing display device for an elevator, wherein a large number of granular projection-forming members are adhered to an interface between the display device dam plate and a wall material with an adhesive. It is.

[0010]

In the present invention, the weir plate plays a role as a mounting member for the display device case in addition to the function as a damming member for the original wall material.

【Example】

Embodiment 1 FIG. An embodiment of the present invention will be described below with reference to FIGS. In the drawings, the same reference numerals as those in FIGS. 5 to 7 indicate the same or corresponding parts. In the figure, 10 is a building wall 1
And a display device dam plate provided between the three-way frame 2 and the display device dam plate 10. The display device dam plate 10 has mounting pieces 10 a and 10 b punched to the size of the case 8. Also serves as a member.

The display device weir plate 10 is formed by extending portions 10c, 1 formed by processing micro joints (leaving ears) in the vertical direction.
Od makes it possible to adjust the width dimension stepwise according to the gap dimension between the building wall 1 and the three-sided frame 2.
Further, mounting holes 11a, 11b are provided in the display device dam plate 10.
Is provided, and the building wall 1 is
It is fixed to. On the other hand, the case 8 and the display device weir plate 10
Is fixed by electric welding 12. Furthermore, the display device dam plate 10 is provided with a granular convex portion forming body 1 made of, for example, styrene foam so that the finishing wall 9 can easily adhere thereto.
The surface is processed by a mortar 13 in which 3a and an adhesive are mixed.

In the hall display device configured as described above, since the periphery of the case 8 is closed by the display device damping plate 10, the back of the case 8 is a space. Therefore, the time required for the installation work of the apparatus is reduced by the amount that the mortar 7 is not packed in this space. Further, since the finishing wall 9 is thin, the problem of its own weight, such as when the conventional mortar 7 is packed, can be ignored.

Since the display device dam plate 10 has numerous protrusions formed on the surface of the mortar 13 including the protrusion forming members 13a, the finishing wall 9 adheres well. Thereby, after the construction, the finishing wall 9 is moved by the vibration or the like to the display device dam plate 1.
This prevents peeling from zero and cracking of the finishing wall 9.

Embodiment 2 FIG. FIG. 4 shows another embodiment. In the first embodiment, the display device weir plate 10 is subjected to microjoining, but a bending material that allows the gap size between the building wall 1 and the three-sided frame 2 to be set flexibly. In the same manner as in the first embodiment, the width of the display device dam plate 10 can be adjusted without the need for a cutting tool.

In the above embodiment, as shown in FIG. 3, the mortar 7 is packed in the gap except for the hall display device as in the prior art, and the mortar 7 is stopped by the weir plate 6. ing. For this reason, it is preferable to provide a horizontal plate at the upper end of the display device dam plate 10 so that the upper mortar 7 does not fall on the back of the case 8. In addition, if the weir plate is arranged at the same position as the display weir plate 10 and the finishing wall 9 is provided on the part other than the hall display device, the work of packing the mortar 7 becomes unnecessary, and the weir plate 6 can be omitted entirely.

Further, in the above-described embodiment, the finishing wall 9 is shown as a wall material. However, the present invention is not limited to this.
May be applied. Furthermore, in the above-described embodiment, the styrofoam is shown as the projection forming body 13, but it may be made of another material such as plastic. Further, in the above embodiment, the mortar 13 is mixed with the projection-forming body 13a and the adhesive. However, the mortar 13 may include only the projection-forming body 13a and the adhesive.

[0018]

As described above, in the elevator hall display device according to the first aspect of the present invention, the display dam plate, which also serves as a mounting member for the display device case, is provided with the building wall around the display device case and the three-sided frame. Since the wall material is provided on the surface of the display device, the mortar does not need to be packed on the back of the display device case, and the time required for the installation work of the device can be shortened. Also, the display device weir
The plate has an extension connected via micro joints
Cut the extension at the position of the micro joint.
The width of the display device dam is adjusted step by step
Since it is possible, the gap size between the three-way frame and the building
Can be easily handled with a common device
You.

In the elevator hall display device according to the second aspect of the present invention, a large number of convex portions are formed on the surface of the display device dam plate by attaching the convex portion forming body with an adhesive.
In addition to the effect of the first aspect of the present invention, there is an effect that the adhesion of the wall material can be improved, and peeling and cracking of the wall material can be prevented.
