Abstract

PROBLEM TO BE SOLVED: To provide the landing doorway frame of an elevator to facilitate assembly. SOLUTION: A vertical frame 1 and an upper frame 2 of which the three-way frame of a doorway consists are provided at respective coupling parts with a protrusion type L-shaped guide part 13 at the vertical frame 1 and a recessed type L-shaped guide hole 17 at the upper frame. When the vertical frame and the upper frame are securely intercoupled to form a three-way frame, the protrusion type L-shaped guide part 13 consisting of right and left vertical frames is inserted in the recessed type L-shaped guide hole 17 of the upper frame. By fixing by a bolt 15 and a nut 19, high-efficient fixing is practicable in a position wherein a vertical frame design surface 1B and the design surface 2B of the upper frame correctly coincide with each other.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an elevator landing doorway frame.

[0002]

2. Description of the Related Art Conventionally, as a method of attaching a landing doorway frame of an elevator, for example, a technique described in Japanese Patent Application Laid-Open No. 51-126542 is widely known. Therefore, such a conventional technique will be described with reference to FIGS.

FIG. 1 is a front view of an entire elevator doorway frame. Reference numerals 1 and 11 denote a vertical frame, 2 denotes an upper frame, and 3 denotes an entrance door. The entrance frame is a combination of the three frames of the vertical frames 1 and 11 and the upper frame 2 and is fixed to the building side wall by welding or anchor bolts using a reinforcing material, and is opened and closed behind the entrance when the elevator gets on and off the elevator. Doorway 3 is installed,
The entrance of the elevator is configured.

FIG. 5 is a detailed view of a frame combination showing an example of the related art, and FIG. 6 is a sectional view thereof. In the conventional combination part, both ends of the upper frame 2A are inserted between the L-shaped bracket 4 and the holding L-shaped bracket 6 provided with a screw hole in the vertical frame 1A back-bent part 1A02 and fastened with screws 10. And vertical frame 1A
Is fixed by the pressing force P generated by the fastening of the screw 10 between the upper end of the L-shaped bracket 4 and the surface of the L-shaped bracket 4. The upper frame 2A is stopped by screws 10, positioned and properly assembled, and then fixed to a building using a reinforcing material.

[0005]

In the above-mentioned prior art, the fixing position of the upper frame 2A with the screw 10 is not specified, and the screw 10 is fastened to an arbitrary position of the upper frame 2A. The frame 1A is temporarily fixed. Since the fixing position is not specified as described above, there is a problem that the work efficiency of the temporary fixing work of the upper frame 2A and the vertical frame 1A is poor.

Further, an adjustment is performed by applying an impact exceeding the pressing force P of the screw 10 so that the design surface 1B of the vertical frame 1A is located within a specified dimension value in the extension of the design surface 2B of the upper frame 2A. After the adjustment, the screw 10 is further tightened, and the pressing force P
And the upper frame 2A and the vertical frame 1A are completely fixed. Since the above adjustment work is repeatedly performed until the adjustment work falls within the specified dimension value, a large amount of time is required, and there is a problem that work efficiency is poor.

[0007]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention comprises a left and right vertical frame having a convex L-shaped guide portion and an upper frame having a concave L-shaped guide hole. When connecting and fixing the upper frame and the upper frame, by inserting the convex L-shaped guide portion into the concave L-shaped guide hole and fixing it with bolts, the left and right vertical frame design surface and the design surface of the upper frame correctly match. It is configured so that it can be fixed at a position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a landing doorway frame for an elevator according to the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of a landing doorway frame of an elevator according to an embodiment of the present invention, and FIGS. 2 and 3 are FIGS.
FIG. 4 is a sectional view taken along line AA in FIG.

FIG. 1 is a front view of an entire elevator doorway frame. Reference numerals 1 and 11 denote vertical frames, 2 denotes an upper frame, and 3 denotes an entrance door. The entrance frame is a combination of the three frames of the vertical frames 1 and 11 and the upper frame 2 and is fixed to the building side wall by welding or anchor bolts using a reinforcing material, and is opened and closed behind the entrance when the elevator gets on and off the elevator. Doorway 3 is installed,
The entrance of the elevator is configured.

Next, a method of combining the three frames of the vertical frame 1 and the upper frame 2 will be described with reference to FIGS.

The vertical frame 1 has a combination portion 12 with the upper frame 2 at an upper portion, and the combination portion 12 has a convex L-shaped guide portion 13 and a hole portion 14a through which a frame fixing bolt 15 passes. It has a metal fitting 14.

The lower surface 2D of the upper frame 2 has a recessed L-shaped guide hole 17 and a hole 18 through which a frame fixing bolt 15 penetrates.

First, the convex L-shaped guide portion 13 of the vertical frame 1
Into the concave L-shaped guide hole 17 from the upper frame combining surface 16 side. Then, as shown in FIG.
3 is inserted so that it cannot be seen from the upper frame design surface 2B direction.

Next, the vertical frame 1 and the frame fixing bolts 1 of the upper frame 1
The frame fixing bolts 15 are respectively provided in the holes 18 through which the holes 5 pass.
Then, the vertical frame 1 and the upper frame 2 are fixed by the frame fixing bolts 15 and the nuts 19 so as to be sandwiched therebetween.

At this time, since the shape of the upper surface portion 13b of the convex L-shaped guide portion 13 of the combination portion 12 of the vertical frame 1 and the shape of the concave L-shaped guide hole 17 of the combination surface 16 of the upper frame 2 are the same, By inserting the convex L-shaped guide portion 13 into the concave L-shaped guide hole 17, the vertical frame 1 can be adjusted without adjustment.
The upper frame 2 and the upper frame 2 can be mounted at predetermined positions.

Accordingly, the work of mounting the design surface 1B of the vertical frame 1 and the design surface 2B of the vertical frame 1 on the same plane within the prescribed specified dimension value can be performed efficiently.

Next, a vertical frame 11 having the same structure as the vertical frame 1 is attached to the combined surface of the other end (not shown) of the upper frame 2 in the same manner as the vertical frame 1.

Thereafter, the vertical frames 1, 11 and the upper frame 2, which are connected and fixed, are fixed to the building using a reinforcing material.

[0020]

As described above, in order to solve the above-mentioned problems, the elevator landing doorway frame of the present invention comprises a left-right vertical frame and an upper frame forming a three-way frame of the doorway.
The left and right vertical frames have convex L-shaped guides on each connecting part,
The upper frame has a concave L-shaped guide hole, and when connecting and fixing the left and right vertical frames and the upper frame to form a three-way frame, the convex L-shaped guide portions of the left and right vertical frames are inserted into the concave L-shaped guide holes of the upper frame. By inserting and fixing with bolts, it is possible to efficiently fix at the position where the design surface of the left and right vertical frames and the design surface of the upper frame correctly coincide on the same plane.
