(6) Mounting work of component 200 Next, the method of the renewal construction of the escalator 10 is demonstrated with reference to FIGS.

  First, the operator removes the old guide rails from the truss 12.

  Next, the worker brings the component 200 of the delivery form shown in FIG. 4 from the factory to the site with the cross beam members 216 and 218 attached.

  Next, the worker carries the component 200 of the loading form shown in FIG. 4 into one block of the inclined section 12c of the truss 12 with the cross beam members 216 and 218 attached.

  Next, the operator deforms the component 200 in the loading form shown in FIG. 4 in a state where the cross beam members 216 and 218 are attached in the mounting form shown in FIGS. 5 and 6. In this case, the upper front guide rail 100, the upper rear guide rail 102, the lower rear guide rail 104, the lower front guide rail 106, the first support column 202, and the second support column 204 are simply connected by the hinge 214. As it is present (see, for example, FIG. 7), it can be easily transformed into a mounting form.

  Next, as shown in FIG. 5, the worker positions the upper back guide rail 102 of the first support column 202, the lower back guide rail 104, and the upper back guide rail 102 of the second support column 204. And the lower rear guide rail 104, a beam member 220 in which metal rods cross in an X shape is attached. The beam member 220 is such that the upper front guide rail 100, the upper rear guide rail 102, the lower rear guide rail 104 and the lower front guide rail 106, and the first support column 202 and the second support column 204 intersect at a right angle. Is a temporary fixing jig.

  Next, the operator fixes the first support column 202 and the second support column 204 to the cross frame member 84 with bolts, with the beam member 220 and the cross beam members 216 and 218 attached.

  Next, with the beam member 220 and the cross beam members 216 and 218 attached, the worker mounts the upper front guide rail 100, the upper rear guide rail 102, the lower rear guide rail 104 and the lower front guide rail 106, and the upper front support. The portion 206, the upper rear support portion 208, the lower rear support portion 210, and the lower front support portion 212 are fixed by bolts. Thereby, the upper front guide rail 100, the upper rear guide rail 102, the lower rear guide rail 104 and the lower front guide rail 106 can be attached to the inclined section 12c inside the truss 12 without distortion.

  Next, the worker removes the cross beam members 216 and 218, the beam members 220 on the left and right, and the hinge 214.

  Next, the worker attaches the component 200 similarly to the other adjacent blocks.

  Next, the worker connects the upper front guide rail 100, the upper rear guide rail 102, the lower rear guide rail 104 and the lower front guide rail 106 of adjacent blocks by a rail joint member (not shown). This completes all the installation work.

(7) Effects According to the present embodiment, after the component 200 of the loading form is carried into the inclined section 12c of the truss 12 at the time of the renewal work of the escalator 10 and deformed into the attachment form, the beam member 220 and the cross beam member The first support post 202 and the second support post 204 are bolted to the lateral frame member 84 while maintaining the correct shape in the state in which the members 216 and 218 are attached. Therefore, the mounting operation is simplified and welding is not required.

  Further, the cross beam members 216 and 218, the left and right beam members 220, and the hinge 214 can be reused at the next renewal work.

Modified example

  In the above embodiment, the left and right pair of first support columns 202 and the left and right pair of second support columns 204 are the component members 200 integrated by the cross beam members 216 and 218, but instead, they are replaced by the left and right Each may form a component 200 and attach each to one side of each block of the truss 12.

  Moreover, although the said embodiment demonstrated by the escalator 10 as a passenger conveyor, it may replace with this and may apply with the moving sidewalk. In the case of a moving sidewalk, there is no part that changes from the horizontal part to the inclined part, so the components 200 can be attached in order for all the space from the entry to the exit.

  Although one embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and the gist of the invention, and are included in the invention described in the claims and the equivalent scope thereof.
