Description

Description: TECHNICAL FIELD The present invention relates to a method for assembling an elevator cab, and particularly to an elevator cab including a step of polymerizing and connecting the overlapping portions of adjacent side plates to each other. The present invention relates to a method for assembling a chamber.

[Prior Art] As a conventional method for assembling an elevator cab of this type,
The technology described in Japanese Utility Model Publication No. 55-74782 can be mentioned.

FIG. 5 is a cross-sectional view of a plane showing a hoistway of a conventional elevator, FIG. 6 is a side view showing a conventional elevator cab, and FIG. 7 is an enlarged cross-sectional view of an essential part of a plane showing an X portion of FIG. FIG. 8 is an enlarged cross-sectional view of a main part of a side surface showing a overlapping portion of a side plate of a conventional elevator cab.

In the figure, 1 is a hoistway wall, 2 is a hoistway, 3 is an elevator cab housed in the hoistway 2, and 4 is a counterweight that is connected to the elevator cab 3 in a slip-like manner. The elevator cab 3 includes a floor plate 31, side plates 32, columns 33, and a ceiling plate.
It is constructed by assembling 34 together. The side plate 32 has overlapping portions 32a having a substantially L-shaped cross section on both sides in the width direction thereof, and a plurality of fastening holes 32b are formed in each overlapping portion 32a in the vertical direction. Reference numeral 5 is a bolt inserted in the fastening hole 32b, and 6 is a nut screwed into the bolt 5.

Next, a method of assembling the conventional elevator cab 3 configured as described above will be described.

First, a predetermined number of side plates 32 are placed on each edge of the floor plate 31 and fastened with bolts (not shown). Next, the bolts 5 are inserted into the corresponding fastening holes 32b of the overlapping portions 32a of the adjacent side plates 32 and tightened with the nuts 6 to fasten the side plates 32 to each other. After that, the pillar 33 and the ceiling plate 34 are fastened to the side plate 32, and the assembly of the box-shaped elevator cab 3 is completed.

[Problems to be Solved by the Invention] Since the conventional elevator cab 3 is configured as described above, when the side plates 32 are fastened to each other, the adjacent side plates 32 on the floor plate 31 are arranged in the vertical direction and the thickness direction. The relative position is adjusted and positioned relative to each other, and the corresponding fastening holes 3 of the overlapping portion 32a
It is necessary to align the 2b with each other and then insert the bolt 5 into the fastening hole 32b to fasten the side plates 32 to each other. At this time, in order to insert the bolt 5 into the fastening hole 32b, the corresponding fastening holes 32b must be perfectly aligned with each other. Therefore, conventionally, one operator holds the side plate 32 and adjusts the positions of the side plates 32 to each other, while another worker tightens the side plates 32 to each other in a narrow space between the side plate 32 and the hoistway 2. However, the assembly work is troublesome and the work efficiency of the assembly is not good. Also, the side plate held by the operator
There is a possibility that the 32 swings during the fastening work, the alignment between the fastening holes 32b is broken, and the fastening work is hindered.

On the other hand, as a prior art, there is a technology disclosed in Japanese Utility Model Publication No. 57-7771. In the technique disclosed in this publication, a protrusion is provided on one of the end faces of the side plates facing each other, and the protrusion is fitted into the engaging hole provided on the other end face to assemble the side plates together, which is narrow. This eliminates the need for tightening in the hoistway and the work of correcting the step difference between the side plates, the number of side plate fastening holes can be reduced, and the assembly can be easily and efficiently performed.

However, the tightening in a narrow hoistway and the work of correcting the step between the side plates are easy if the step on the side plate end face and the engaging hole on the other end face are fitted to each other. However, in reality, it is difficult to fit the protrusions of the end faces of the side plates facing each other and the engagement holes formed in the other end face to each other, and the workability cannot be improved.

Therefore, it is an object of the present invention to provide a method for assembling an elevator cab, which enables the side plates to be easily fastened to each other and has improved assembly work efficiency.

[Means for Solving the Problem] In the method for assembling an elevator cab according to the present invention, the overlapping portions of the widthwise edges of adjacent side plates are overlapped with each other, and a positioning hole provided in the overlapping portion has a substantially L shape. A bent bar member is inserted to position the both side plates with respect to each other, and a fastener is inserted into a fastening hole provided in the overlapping portion to fasten the both side plates to each other.

[Operation] In the present invention, the rod members are inserted into the positioning holes of the overlapping portions of the side plates so that the adjacent side plates are positioned with each other, and the friction between the rod member outer peripheral surface and the positioning hole inner peripheral surface is achieved. The force causes the two side plates to be fixed to each other, and the corresponding fastening holes in the two side plates are aligned with each other. This facilitates position adjustment between the side plates and insertion of the fastener into the fastening hole.

[Examples] Examples of the present invention will be described below.

FIG. 1 is a partially enlarged plan view showing a state in which the Shino of one embodiment of the present invention is fitted and fixed in the positioning hole of the overlapping portion of the side plate, and FIG. 2 is a perspective view showing how to use the Shino. In the drawings, the same reference numerals and symbols as those of the conventional example indicate the same or corresponding parts as those of the conventional example, and therefore, redundant description will be omitted here.

In the drawing, reference numeral 11 is a Shino as a bar member formed by bending a bar material having a substantially quadrangular cross section into a substantially L shape, and the base end of the bent portion is slightly inclined toward the tip to be tapered. The fitting fixing portion 11a is formed, and the tip of the fitting fixing portion 11a has a taper portion 1 which is tapered at a steeper angle than the fitting fixing portion 11a.
1b is formed continuously. The inclination angle of the tapered portion 11b is selected so that the tip end thereof is sufficiently thinner than the base end thereof, that is, the tip end of the fitting and fixing portion 11a.

On the other hand, 12 corresponds to the outer peripheral surface of the fitting fixing portion 11a of the Shino 11 in the longitudinal direction at a position that does not correspond to the fastening holes 32b in the upper and lower portions of the overlapping portion 32a of the side plate 32 (only the upper portion is shown). Is a positioning hole for a square hole formed in a substantially square shape. The positioning hole 12 has a tapered portion 11b on the shino 11.
The fitting fixing portion 11a is inserted, and the outer peripheral surface of the fitting fixing portion 11a at the substantially central portion in the longitudinal direction is fitted and fixed to the inner peripheral surface of the positioning hole 12.

Next, a method of assembling the elevator cab 3 of the present embodiment configured as described above will be described.

First, after fastening the side plate 32 to the floor plate 31, the adjacent side plate 32
The overlapping portions 32a are overlapped with each other, and the upper positioning holes 12 of the corresponding positioning holes 12 in both overlapping portions 32a are aligned with each other. At this time, it is not necessary to completely align the both positioning holes 12, and it is sufficient that there is a superposed portion between the both positioning holes 12 such that the tip of the tapered portion 11b of the shino 11 which is sufficiently tapered can be inserted.

Then, the tip of the tapered portion 11b of the sino 11 is first inserted on the inner peripheral surfaces of both the positioning holes 12, and further, the tapered portion 11b and the fitting fixing portion 11a continuous thereto are inserted into the positioning hole 12. . At this time, the tapered portion 11b inclined at a steeper angle than the fitting fixing portion 11a functions as a guide, and facilitates the insertion of the fitting fixing portion 11a into the positioning hole 12. Also,
Even if there is a displacement between the corresponding positioning holes 12, as the tapered portion 11b and the fitting fixing portion 11a enter into the positioning hole 12, the outer peripheral surfaces of the tapered portion 11b and the fitting fixing portion 11a are positioned. Sliding contact with the inner peripheral surface of 12 and pressing both positioning holes 12 in the direction to eliminate the positional deviation, both positioning holes 12
The positional deviation between them is eliminated, both positioning holes 12 are perfectly aligned, and relative position adjustment is performed between adjacent side plates 32.

Further, when the fitting fixing portion 11a is in close contact with the inner peripheral surface of the positioning hole 12 at the outer peripheral surface of the substantially central portion thereof and the fitting fixing portion 11a cannot be further inserted into the positioning hole 12, the fitting 11 of the shino 11 is fitted. The fitting and fixing portion 11a is fitted and fixed in the positioning hole 12 by hitting or rocking the base end portion of the fitting and fixing portion 11a with a hammer or the like.

Furthermore, similarly, by inserting the fitting 11 into the positioning hole 12 below the overlapping portion 32a of the side plate 32 and fitting and fixing the same,
The adjacent side plates 32 are connected and fixed so that they cannot move relative to each other while being positioned with respect to each other.

Then, in the overlapping portions 32a of the side plates 32, the corresponding fastening holes 32b and the bolts 5 serving as fasteners are inserted and the nuts 6 are screwed together to fasten the side plates 32. After that, the shino 11 is removed from the positioning hole 12 for use in positioning the other adjacent side plates 32. Similarly, the adjacent side plates 32 are fastened to each other, and finally the pillar 33 and the ceiling plate 34 are connected to each other.
And the whole assembly work is completed.

As described above, according to the method of assembling the elevator cab 3 of the above-described embodiment, the taper portion 11b and the fitting fixing portion 11a of the Shino 11 are inserted into the positioning holes 12 provided in the overlapping portions 32a of the adjacent side plates 32 to perform positioning. After the side plates 32 are positioned with respect to each other by fitting and fixing the fitting fixing portion 11a in the hole 12, the overlapping portion 32a
The both side plates 32 are fastened to each other by inserting the bolt 5 into the fastening hole 32b provided in the above and screwing the nut 6 therein.

Therefore, in the above-described embodiment, the overlapping portion of the adjacent side plates 32 is used.
At the stage of inserting the bolt 5 into the corresponding fastening hole 32b of 32a, both fastening holes 32b are completely aligned, and both side plates 32 are also fixed relative to each other by the Shino 11 so that they cannot move relative to each other. There is no risk of displacement between the fastening holes 32b. As a result, it is not necessary for the worker to hold the side plate 32 during the fastening work, and even if there is only one worker, the fastening hole 32b
Since the bolt 5 can be easily inserted into the elevator car 3, the side plate 32 can be easily fastened, and the efficiency of assembling the entire elevator cab 3 is improved.

Also, when adjusting the positions of the side plates 32, the positioning holes
It is not necessary to completely align 12 with each other, and if the corresponding positioning hole 12 is overlapped to the extent that the tapered portion 21b of the shino 21 that is sufficiently tapered can be inserted, the tapered portion 21b of the shino 21 will be aligned with the positioning hole 12. In the process of inserting the fitting fixing portion 21a and the fitting fixing portion 21a, the taper portion 21b and the fitting fixing portion 21a correct the positional deviation between the positioning holes 12, align the positioning holes 12 and adjust the mutual positions of the side plates 32. Is done automatically. Therefore, the operator does not need to pay close attention to the position adjustment of the side plates 32 as in the conventional case, and the position adjustment work of the side plates 32 can be performed quickly and easily.

Further, as the member for positioning the side plates 32 relative to each other, since the Shino 21 which can be manufactured at low cost by bending the bar is used, the manufacturing cost of the entire elevator cab 3 is less affected.

By the way, the Shino 21 of the above-mentioned embodiment is constructed by bending a bar member having a substantially rectangular cross section into a substantially L shape, but the present invention is not limited to this and the fitting is not limited thereto. If the mating and fixing portion 21a has an outer diameter corresponding to the positioning hole 12 of the overlapping portion 32a of the side plate 32 and is fitted and fixed in the positioning hole 12 and functions to perform mutual positioning of the adjacent side plates 32. Good. Examples thereof are shown in FIGS. 3 and 4.

FIG. 3 is a partially enlarged plan view showing a state in which the Shino is fitted and fixed in the positioning hole of the overlapping portion of the side plate by the method of assembling the elevator cab according to another embodiment of the present invention, and FIG. FIG. 6 is a perspective view showing how to use the Shino in the method of assembling the elevator cab of the embodiment of FIG. It should be noted that, in the drawings, the same reference numerals and symbols as those in the first embodiment show the same or corresponding constituent portions as those of the first embodiment, and therefore, duplicated explanations are omitted here.

As shown in FIGS. 3 and 4, a bar material having a circular cross section is bent into a substantially L shape to form a shino 21, and the side plate is formed in accordance with the outer peripheral surface shape of the fitting fixing portion 21a. The positioning hole 22 of the overlapping portion 32a of 32 may be formed in a substantially circular round hole.

That is, the Shino 21 for carrying out the invention of this type can be formed by a bar material having an elliptical, triangular, pentagonal or more pentagonal, or rounded polygonal cross section. However, when the Shino 11 and 21 are implemented as a simple cross section such as a circle or a square, including the above-described embodiments, the effect that the Shino 11 and 21 are easily manufactured can be obtained. Furthermore, Shino 11,2
It is also possible to make the fitting and fixing portion of 1 and other portions different in cross-sectional shape, and to make the joints 11 and 21 linear without bending in a substantially L shape.

Further, the positioning hole 22 of this embodiment is the overlapping portion of the side plate 32.
Although it is constituted by the positioning holes 22 provided on the upper and lower sides of the 32a, the present invention is not limited to this, and the side plates adjacent to each other in cooperation with the fitting fixing portion 21a of the Shino 21. 32 Anything that functions to perform mutual positioning may be used. For example, a part of the fastening hole 32b is also used as a positioning hole, and after the bolt 5 is inserted into the other fastening hole 32b and the nut 6 is screwed into it, the fastening hole is also used as a positioning hole.
It is also possible to remove the Shino 21 from 32b and insert the bolt 5 in those fastening holes 32b. However, when the positioning hole 12 and the fastening hole 32b are separately formed in the overlapping portion 32a of the side plate 32, the side plate 32 can be fastened more quickly. Note that three or more positioning holes 12 may be provided in the overlapping portion 32a of the side plate 32.

By the way, the Shino 11 and 21 of the above-mentioned embodiment are the adjacent side plates 3
Although it is configured to be removed from the positioning holes 12 and 22 after fastening 2, the present invention is not limited to this, and the positioning holes 12 and 22 are fitted with the shinos 11 and 21. It is also possible to assemble the elevator apparatus 3 with the joint fixed. However, after fastening the side plate 32, the positioning holes 12, 2
In the case of implementing as a configuration to remove Shino 11, 21 from 2,
The shinos 11 and 21 can be used for fastening work between other adjacent side plates 32, and the effect of contributing to the reduction of the manufacturing cost of the entire elevator cab 3 is obtained.

[Effects of the Invention] As described above, in the method for assembling the elevator cab according to the present invention, the rod member is inserted into the positioning hole provided in the overlapping portion to position the adjacent side plates relative to each other, and then the fastening is provided in the overlapping portion. Since the both side plates are fastened to each other by inserting the fasteners into the holes, by inserting the bar member into the positioning hole of the overlapping portion of the side plate, the side plates adjacent to each other are positioned and the outer periphery of the bar member is The both side plates are fixed to each other by the frictional force between the surface and the inner peripheral surface of the positioning hole, and the corresponding fastening holes in the both side plates are aligned with each other. This allows
By analogy, even if there is a step between the side plates, the position adjustment of the side plates and the insertion of the fastener into the fastening hole are facilitated, the side plates can be easily fastened together, and the assembly work efficiency is improved.
