DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a positioning device for a three-sided elevator landing frame and a method for attaching a three-sided elevator landing frame.
The present invention relates to a positioning device for a three-sided frame for an elevator hall, and a method for attaching a three-sided frame for an elevator hall, for attaching a three-sided frame forming an entrance/exit to a wall surface of an elevator hall at a predetermined position.

[Prior Art] As a conventional positioning device of this kind for a three-sided elevator landing frame and a method for attaching a three-sided elevator landing frame, Japanese Patent Laid-Open No. 6
The technique disclosed in Japanese Patent No. 2-8988 can be mentioned.

Figures 5 and 6 relate to the conventional three-sided elevator landing frame positioning device and the mounting method for the elevator landing three-sided frame published in the above-mentioned publication. FIG. 6 is an enlarged sectional view taken along the line A-A in FIG. 5; FIG.

In the figure, (1) is the floor of the elevator hall, (2) is the wall forming the entrance/exit opening (2a) in the hall, and (3) is the floor of the elevator hall.
is a three-sided frame that is smaller than the opening (2a) so as to leave some gaps (δ) on the top, bottom, left and right sides of the opening (2a), and in the three-sided frame (3), the lower end of the vertical frame (3a) is on the floor (1). Upper threshold (4)
Furthermore, they are positioned and fixed via reinforcing bars (6) to welding anchors (5) attached at predetermined intervals to the side edge (2b) of the wall (2). In order to fix the three-sided frame (3) to the welding anchor (5) via this reinforcing bar (6), as shown in Fig. 5, the vertical frame (
Reinforcing bars (6) are welded to the reinforcing plate (3b) attached to 3a).

In addition, (7) is a wedge for positioning and fixing the three-sided frame (3) with respect to the opening (2a) of the wall (2), and (8) is a wedge for confirming the longitudinal and horizontal inclination of the three-sided frame (3). This is a plumb bob that serves as a reference, and the wedge (7) adjusts the inclination of the three-sided frame (3) in each of the front, rear, left, and right directions to center it perpendicularly to the floor (1). In addition, (9) connects the threshold (4) to the floor (1
) is a bracket that is fixedly supported on the

Next, a method of attaching the three-sided frame (3) using the wedges (7) will be explained.

First, place the lower end of the vertical frame (3a) of the three-sided frame (3) on the floor (1).
It is fixed to the sill (4) fixed to the wall edge (2).
Adjust the gap (δ) formed between b) and the three-sided frame (3), and drive wedges (7) from both the front and back sides of the wall (2) as shown in Figure 5. Adjust the longitudinal inclination of the three-sided frame (3) with the plumb bob (8), and adjust the slope of the wedge (7) (
Adjust the centering according to step 7a). At this time, as shown in the figure, the same wedge (7) is placed on both sides of the vertical frame (3a) of the three-sided frame (3).
By driving, the inclination of the three-sided frame (3) in the front-rear direction as well as in the left-right direction is adjusted at the same time.

After adjusting the three-sided frame (3) in this way, the welding anchor (5) planted on the side edge (2b) of the wall (2) and the three-sided frame (3)
) and the reinforcing plate (3b) are welded to fix the three-sided frame (3), and the centering work and installation work of the three-sided frame (3) is completed.

In addition, as well as the centering work and installation work of the three-sided frame (3), the installation work of the sill (4) is also important, and Japanese Utility Model Publication No. 61-43816 describes an installation jig for the elevator landing sill. The technology has been disclosed. However, this is not directly related to the centering work and installation work of the three-sided frame (3). A detailed explanation thereof will be omitted.

[Problems to be Solved by the Invention] In the conventional elevator landing three-sided frame positioning device and elevator landing three-sided frame mounting method as described above, the wedge (7) is exclusively used to move the three-sided frame (3). I was performing centering and installing the three-sided frame.

The work of driving in such a wedge (7) and adjusting the centering of the three-sided frame (3) required the experience and intuition of the person performing the work. Moreover, although this requires skill, the temporary fixing of the three-sided frame (3) with the wedges (7) is not necessarily accurate, and the welding anchor (5) is attached to the welding anchor (5) via the reinforcing bar (6). On the other hand, the three-sided frame (3) moved while the three-sided frame (3) was being permanently fixed, and the standing position was not always good.

For this reason, a positioning device for a three-way frame for elevator landings has been devised, which does not require the operator to be skilled and which does not cause misalignment during the final fixing of the three-way frame (3) to the wall edge (2b). Ta.

These techniques are published in, for example, Japanese Utility Model Application Publication No. 55-41481 and Japanese Utility Model Application Publication No. 61-200878.

The technology described in the former publication consists of a rectangular bar-shaped main body disposed across the three-sided frame (3), an engager corresponding to the entrance/exit width dimension, a temporary fixing device, and a predetermined reference position corresponding to the main body. This is an index that has been established to In addition, the technology described in the latter publication involves fixing a mounting rod installed on the landing side to a clamping tool that clamps the wall (2) of the landing opening, and attaching the three-sided frame (3) to the mounting rod. A holder for holding the holder is fastened to the mounting rod via a movable tube that is loosely fitted.

However, in the former technique, since the engager is fixed to the square rod-shaped main body, the three-sided frame (
3) could not be used and had poor versatility. Further, since the engaging element is located between the left and right vertical frames (3a) of the three-sided frame (3), it may become difficult to remove the engaging element if the three-sided frame (3) is fixed first. On the other hand, in the latter technique, both the left and right vertical frames (3a) of the three-sided frame (3) are individually positioned relative to the left and right walls of the opening (2a), and Regarding whether or not the entire three-sided frame (3) has a certain positional relationship, again,
I had to adjust. Moreover, it is necessary to accurately perform each operation of positioning the holding rod and the holder and holding the three-sided frame (3) on the holder with respect to a predetermined baseline.
There was a risk that an error would occur in the positioning of the three-sided frame (3). Furthermore, since a clamping tool is attached to clamp the wall (2) of the hall opening from the hall side, there is a risk that the wall surface on the hall side may be damaged.

Therefore, the present invention provides a versatile three-sided frame positioning device for elevator halls that does not require operator skill, can accurately position the three-sided frame, and can also position the entire three-sided frame with respect to the opening. The challenge is to provide this information. Another object of the present invention is to provide a method for attaching a three-way frame for an elevator hall, in which the three-way frame for an elevator hall can be accurately and quickly attached to an opening by using this positioning device for a three-way frame for an elevator hall.

[Means for Solving the Problem] The positioning device for a three-sided elevator hall frame according to the present invention locates the opening (2a) formed in the wall (2) of the elevator hall at approximately symmetrical positions on both left and right vertical wall surfaces. A reference rod member (12) is placed horizontally between the receiving members (11) to be installed, and a reference rod member (12) is installed on the reference rod member (12) and is placed on both sides of the three-sided frame (3). Temporary fixing means for temporarily fixing the three-sided frame (3) by adjusting the frames (3a) to respective predetermined positions, and the reference rod member (12) and the temporary fixing means are arranged with reference to the indicator means. It is to be established.

Furthermore, the method for attaching the three-sided frame for an elevator landing according to the present invention includes an opening (2a) formed in the wall (2) of the elevator landing.

) is positioned and temporarily fixed, the three-sided frame (3) is permanently fixed to the wall (2) of the elevator hall, and the reference rod member (12
) and the receiving member (11) are removed.

[Operation] In the three-sided elevator landing frame positioning device of the present invention, the opening (2a) formed in the elevator landing wall (2)
The receiving members (11) are installed at substantially symmetrical positions on both the left and right vertical walls of the
2) is suspended horizontally, its position in the front, rear, left and right directions is adjusted, and the three-sided frame (3) is temporarily fixed to the reference rod member (12) while being arranged in a horizontal state with reference to the index means. The fixing means is adjusted so that both vertical frames (3a) of the three-sided frame (3) have a predetermined positional relationship, and is arranged based on the indicator means, so that the center of the three-sided frame (3) Ejecting and positioning work is easy, and the three-sided frame (3) can be easily moved to the wall edge (2).
b) The three-sided frame (3) will not shift its position and cause silkworms during the final fixation, and both vertical frames (3) on the left and right of the three-sided frame (3)
a) can be positioned together, and can also be used for three-sided frames (3) with different entrance/exit width dimensions.

In addition, in the method for attaching a three-sided elevator hall frame of the present invention, the positioning device for the three-sided elevator hall frame is used to attach the receiving member (11) to both left and right vertical wall surfaces of the opening (2a).
), and the reference rod member (12) is temporarily fixed in a horizontal state between both the receiving members (11), and this reference rod member (
12) in the front, rear, right and left directions, and then permanently fixing it. Then, after positioning and temporarily fixing the three-sided frame (3) to this reference rod member (12), the elevator landing wall (
2), and then the positioning device for the three-sided elevator landing frame is removed, so the three-sided frame (3)
The centering and positioning work of the three-sided frame (3) can be easily and accurately carried out, and the entire three-sided frame (3) can be attached together.

The frame (3) can be installed quickly, and three-sided frames (3) with different entrance/exit width dimensions can also be installed.

By the way, in each of the above embodiments, the vertical wall surface on the hoistway side (2C
), insert the anchor bolt (10) into the notch (11d) in the vertical surface (1l b) of the receiving member (11), and attach the receiving member (11) to both the left and right walls ( 2c) were installed at approximately symmetrical positions, but the side edges (2c)
b), and using this anchor bolt (10) and the notch (11d) in the vertical surface (11a) of the receiving member (11), attach the receiving member (11) to both the left and right walls. They may be attached to substantially symmetrical positions as shown in (2c).

Further, in each of the above embodiments, the receiving member (11) is attached to both the left and right wall surfaces (2c) located on the hoistway side of the opening (2a) formed in the wall (2) of the elevator hall. (11) The reference rod member (12) was horizontally suspended between the openings (2a) and arranged in a horizontal state.
You may use both the left and right wall surfaces on the landing side in 2a).

[Effects of the Invention] As described above, the positioning device for a three-sided elevator hall frame of the present invention includes a receiving member, a reference rod member, a temporary fixing means, and an index means, and the receiving member is installed on the wall of the elevator hall. The reference rod member is mounted horizontally on both the left and right walls of the opening, and the reference rod member is suspended horizontally between these receiving members, and its position in the front, rear, left, and right directions is adjusted, and the reference rod member is placed in a horizontal state with reference to the index means. At the same time, a temporary fixing means for temporarily fixing the three-sided frame to the reference rod member is adjusted so that both frames of the three-sided frame are in a predetermined positional relationship, and arranged with the index means as a reference. This makes it easy to center and position the three-sided frame.
Since the three-sided frame does not shift its position before it is permanently fixed to the wall edge, the three-sided frame can be positioned easily and accurately, and both the left and right frames of the three-sided frame can be placed together. It can be positioned on three sides and can also be used for three-sided frames with different entrance/exit widths, resulting in good work efficiency and versatility.

Moreover, the method for attaching the three-sided frame for elevator landings of the present invention is as follows:
A receiving member mounting process, a reference bar member temporary fixing process, a reference bar member permanent fixing process, a three-sided frame temporary fixing process, a three-sided frame main fixing process, and a jig removal process, and the method is for the elevator landing. Using a three-sided frame positioning device, attach the receiving members to both the left and right walls of the opening, and temporarily fix the reference rod member in a horizontal state between the two receiving members. After positioning in the left and right direction, the three-sided frame is finally fixed, and after the three-sided frame is positioned and temporarily fixed with respect to this reference rod member, it is finally fixed to the wall of the elevator hall, and then the three-sided frame for the elevator hall is finally fixed.
