[Problems to be solved by the invention]

The above-mentioned prior art is a system in which the second passenger conveyor which is almost completed by diverting only the existing main body frame 8 is stored as it is. For this reason, no consideration was given to the method of remodeling only the balustrade, which is the design surface with the highest market needs, and to what point.

Generally, the remodeling method using only balustrades is as follows. First, all existing balustrades are dismantled, and columns are erected on the main frame of the machine room 1 and the main frame of the lower machine room (not shown). A piano wire. The centering of the piano wire is adjusted so as to pass over the center of the main body frame, that is, the vertical upper portion of the center of the step 5. Assembling of new balustrades is performed based on this piano wire. Generally, this piano wire is hung with a weight attached to the piano wire, and the components of the left and right balustrades are centered on this thread while accurately checking the dimensions so that they are symmetrical. is there. Although the method using the pretend swing is accurate, the piano wire may move quickly due to interference with the installation work, vibrations occurring during the work, or touching the piano wire when the worker moves. Therefore, there is a problem that it takes time to check and install the dimensions. In particular, when the work is carried out simultaneously at two places above and below the passenger conveyor or at other places in order to shorten the work time, the above-mentioned problem occurs remarkably, and the work is practically impossible.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for remodeling a passenger conveyor railing, which can improve work efficiency.

[Means for solving the problem]

In order to achieve the above object, according to the present invention, a main body frame is fixedly installed in a building, an endless step is movably attached to the main body frame, and fixed to both side edges of the step so as to face each other. In the remodeling work method of the passenger conveyor balustrade, the work process is to disassemble only the balustrade on one side with a step in between, and the first phase construction to remodel to a new balustrade and the existing balustrade on the remaining side are demolished. And the second phase of the project, which will be converted to a new balustrade.

[Action]

As described above, in the first phase construction, the present invention is based on the existing balustrades left without being dismantled, and in the second phase construction, the new balustrades installed in the first phase construction are installed. As it is possible to assemble a balustrade of the latest design, it is not necessary to attach a piano wire for centering or to install a centering using a flier, so that a new balustrade can be assembled efficiently and accurately. .

〔Example〕

Hereinafter, a method for remodeling a passenger conveyor railing according to the present invention will be described with reference to the drawings.

FIG. 1 is an explanatory view showing one embodiment of a method for remodeling a passenger conveyor railing according to the present invention. The basic work process is divided into two phases, a first phase construction and a second phase construction, and normal operation is possible between the first phase construction and the second phase construction.

The first phase of the construction is carried out from the night before the regular holiday of the building to the morning of the next day after the regular holiday, and as shown in the transitional period of FIG. Remodel to balustrade.

The second-stage construction is a work for remodeling the balustrade on the right side, and is performed, for example, from the night before the regular holiday one week after the specific day to the morning of the next day after the regular holiday.

FIG. 2 is a cross-sectional view of the balustrade of the passenger conveyor to which the method of this embodiment is applied, particularly in a state where the first-stage construction has been completed.

The existing balustrade 7a has a pillar 9 fixed to the main body frame 8 of the passenger conveyor with bolts 8a as a support, and a handrail frame 10 is mounted on an upper portion of the pillar 9 and a handrail is provided along the upper surface of the handrail frame 10. 6a is rotated. On the lower side, a skirt guard 12a is attached via a skirt guard adjustment bracket 11, and
Is adjusted so that shoes or the like do not get caught in the gap. The space between the skirt guard 12a and the handrail frame 10 is covered with a balustrade panel 13 using a stainless steel panel or the like.

On the other hand, the modified balustrade 7b, like the existing balustrade 7a, is assembled above the bracket 14 fastened to the main body frame 8 with bolts 8b, and the upper part is supported by the glass panel 15 made of transparent tempered glass. The new handrail 6b is rotated via the handrail guide 16. The lower side is a stainless steel plating cover 17 and a stainless steel skirt guard 12b
Is fixed to the bracket 14.

As a method of the remodeling work, first, all the steps 5 are removed. It fell during the dismantling and assembly of the balustrade,
To prevent problems such as damage to equipment when the passenger conveyor is restarted after bolts, nuts, small parts, etc. return on the upper surface or inside the step 5 or on the traveling rail 18 and restart the passenger conveyor. Do. Next, after dismantling the existing balustrades erected on the left main body frame 8, the brackets 14 are centered and fixed at intervals in the longitudinal direction of the main body frame 8. The centering and fixing method is, for example, using the balustrade 7a on the opposite side as a reference and setting the surface of the skirt guard 12a as a reference surface. At this time,
It is convenient to use a gauge as shown in FIG. This gauge is provided with small balls 19a and 19b at both ends, and the distance 1 between the small balls can be adjusted arbitrarily. A level 21 is attached to the main body 20.

The centering method is as follows: the dimension 1 between the small balls 19a and 19b is set to the interval L1 between the skirt guard 12a after modification and the bracket 14, and _one of the small balls is applied to the surface of the existing skirt guard 12a, and the level 21 Level the gauge body with. In this state, move the other ball and move the bracket to the farthest position.
Just set 14. Next, the balustrade unit parts assembled in the manufacturing plant equipped with the production equipment, that is, the ones composed of the glass panel 15, the handrail guide 16, the deck cover 17, etc., and assembled in a transportable size, are supplied to the bracket 14. Align and fix on top. In this case, likewise using the gauge of FIG. 3, if Suetsukere by excisional the l size for example in the excisional distance L ₂ between the existing handrail frame 10 and the handrail guide 16 and centered in the same way Good.

Finally, the step 5 is assembled, the skirt guard 12b is attached while adjusting the gap with the step 5, and the first phase construction is completed.

Next, the remodeling work of the balustrade on the opposite side as the second phase construction can be carried out by using the surface of the glass panel 15 of the new balustrade 7b, the surface of the skirt guard 12b, etc. as a reference.

As a work procedure, it goes without saying that there is no problem even if the remodeling work is first performed from the right balustrade. In addition, there is no problem even if the work is completed only by remodeling the balustrade on one side from the aspect of design, or from the connection between the building and the passenger conveyor.

According to this remodeling method, between the first phase construction and the second phase construction, it is possible to obtain a piece that enables normal operation of the passenger conveyor. For example, the first phase construction is closed from the night before the regular holiday of the building. If the second phase of construction is carried out until the morning following the day and the second phase of construction is carried out in the same manner on the next regular holiday, the balustrade design can be efficiently and easily renewed without stopping the passenger conveyor. .

〔The invention's effect〕

According to the present invention, a new balustrade can be installed on the basis of the balustrade left without being dismantled, so that it is not necessary to stretch the piano wire for centering in the longitudinal direction of the passenger conveyor,
The centering and fixing operation using the swivel can be eliminated. As a result, the efficiency of workability can be improved, and many workers can collectively carry out remodeling work on one passenger conveyor balustrade without hurting other people's work. This has the effect of greatly reducing the time.
