Description

[Detailed description of the invention] [Industrial application field] This invention is a method for fixing an intermediate panel installed between each elevator landing and a three-sided frame of each elevator landing when multiple elevators are installed in parallel. This relates to improvements in equipment.

[Conventional technology]

The conventional fixing device between the middle panel and the three-sided frame has been replaced with a third one.
This will be explained with reference to the drawings and FIG.

Figure 3 is a front view of a hall where two elevators are installed side by side, 1 is a three-sided frame, 2 is a hall door, 3 is a car position indicator light and a hall call button, 4 is an intermediate panel, 5 is a ceiling, 6 is the floor. FIG. 4 is an enlarged sectional view taken along the line A-A in FIG. It is fixed to wall 8. The facing part of the three-sided frame 1 and the middle panel 4 is
Folded piece 1 is bent inward at almost a right angle.
a, 4a are bent outward at almost right angles to form overlapping pieces 1b, 4b, and one overlapping piece 1
The elongated hole provided in b and the round hole provided in the other overlapping piece 4b are fixed by bolts and nuts 10. In addition, a gap B is provided in order to absorb manufacturing errors, installation errors, and construction errors of each member, and changes in the gap B are absorbed by the elongated holes of the overlapping pieces 1b. 11 is a joint;
After installing and fixing the three-sided frame 1, intermediate panel 4, etc.,
It is inserted into the gap B and fixed to the three-sided frame 1 and the intermediate panel 4 with adhesive.

[Problem that the invention attempts to solve]

In the case of the above-mentioned conventional device, the dimensions of the gap B differ for each floor landing due to installation errors, etc., so the width of the joint 11 is made slightly wider in advance, and the three-sided frame 1
After completing the installation, make joint 1 at the site according to gap B.
1 had to be processed, which had the disadvantage of requiring an enormous amount of work time. Another drawback was that the adhesive protruded between the joints 11, the three-sided frame 1, and the intermediate panel 4, spoiling the design.

[Means for solving problems]

In the present invention, the mutually facing parts of the three-sided frame 1 and the middle panel 4 are each bent inward at an acute angle, and then bent outward at the same angle, so that the space formed by the facing parts is narrow and deep. The width of the joint is wide, and the joint is held by the bolt and the bent piece by pushing the joint from the back to the mouth with the bolt.

[Effect]

According to the present invention, when the gap B is narrow, the joint only needs to be located on the back side, and when it is wide, it is only necessary to position it on the opening side, and it is possible to respond to changes in the gap B without changing the width of the joint. .

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 and 2. As shown in FIG. 2, the three-sided frame 1 and the intermediate panel 4 are bent inward at acute angles X and Y to form bent pieces 1a and 4a, and then bent outward at the same angles X and Y to form overlapping pieces. 1b, 4b
is formed. In other words, the cross section is Z-shaped. The overlapping piece 1b of the three-sided frame 1 has a long hole 12 whose major diameter is horizontal, and in addition to the number required for fixing the three-sided frame 1 and the intermediate panel 4, the number of bolts 18 required to hold the joints 17 described below only. on the other hand,
A round hole 13 is provided at a position corresponding to the elongated hole 12 in the overlapping piece 4b of the intermediate panel 4, and a nut 14 is welded thereto. 15 is a bolt, which passes through the washer 16, the elongated hole 12, and the round hole 13, and then attaches to the nut 1.
5, the three-sided frame 1 and the overlapping pieces 1b, 4b of the intermediate panel 4 are fixed.

FIG. 1 shows a fixing device for the joint 17, and the elongated hole 12, round hole 13, and nut 14 are the same as in FIG. 2. Both ends of joint 17 are at angles X and Y
The three-sided frame 1 and the bent pieces 1a and 4b of the intermediate panel 4 come into surface contact with each other. Bolts 18 are screwed onto the nut 14, pass through the round hole 13 and the elongated hole 12, and push the joint 17 from the back side to the opening side (in the direction of arrow C), and are provided in an appropriate number in the vertical direction.

When attaching the joint 17 according to this embodiment,
First, as explained in FIG. 2, the three-sided frame 1 and the intermediate panel 4 are fixed with bolts 15. Next, joint 17
Insert it from above and use the bolt 18 to push it from the back side to the mouth side and fix it. That is, the joint 17 is held by the bent piece 1a of the three-sided frame 1, the bent piece 4a of the intermediate panel 4, and the bolt 18.

Because of the above configuration, when the gap B is wide, the joint 17 is located on the opening side (arrow C side), and when the gap B is narrow, the joint 17 is located on the back side (opposite the arrow C side). Gap B without changing the width of joint 17
can respond to changes in

In addition, if the gap B is too wide to accommodate the joint 17, as shown by the dashed line in Figure 1, the joint 1
Just turn 7 over. In this case, although the bent pieces 1a and 4a of the three-sided frame 1 and the intermediate panel 4 and the joint 17 do not come into surface contact, there is no problem in practice. Furthermore, the contact portions of the joints 17 with the bent pieces 1a, 4a may have other shapes such as an arc shape. Further, the bending angles X and Y may be the same, and the nut 14 may be tapped instead of being welded.In short, any structure that can hold the bolts 15 and 18 may be used. Furthermore, in this embodiment, the three-sided frame 1
The overlapping piece 1b is on the joint side, and the overlapping piece 4 of the intermediate panel 4
Although b is polymerized on the side opposite to the joint, it goes without saying that it may be the other way around.

[Effect of idea]

According to the present invention, even if the gap between the three-sided frame and the middle panel changes, there is no need to process the joints on site, and the joints manufactured at the factory can be used as they are, reducing installation time. can. Furthermore, since there is no need to use adhesive, there is no fear that the adhesive will come out unlike in the past, and it is possible to provide an elevator entrance device with excellent design.
