Therefore, it can be three-dimensionally transformed from the carry-in form to the attachment form.

(6) Installation work of component member 200 Next, a method of renewal construction of the escalator 10 will be described with reference to FIGS.

  First, the operator removes each old guide rail from the truss 12.

  Next, the operator brings in the carrying-in configuration member 200 shown in FIG. 4 from the factory to the site with the cross beam members 216 and 218 attached.

  Next, the operator carries the component member 200 in the carry-in 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 worker deforms the carrying-in configuration member 200 shown in FIG. 4 with the cross beam members 216 and 218 attached to the attachment configuration shown in FIGS. 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 merely connected by the hinge 214. For example (see, for example, FIG. 7), it can be easily transformed into a mounting form.

  Next, as shown in FIG. 5, the operator places the position of the upper rear guide rail 102 of the first support column 202, the position of the lower rear guide rail 104, and the upper rear guide rail 102 of the second support column 204. Between the lower rear guide rail 104, a beam member 220 in which metal bars cross in an X shape is attached. The beam member 220 allows 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 to 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 horizontal frame member 84 with bolts while the beam member 220 and the horizontal beam members 216 and 218 are attached.

  Next, with the beam member 220 and the cross beam members 216 and 218 attached, the operator supports the upper front guide rail 100, the upper rear guide rail 102, the lower rear guide rail 104, 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 with bolts. Accordingly, 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 operator removes the transverse beam members 216 and 218, the beam members 220 on the left and right, and the hinge 214.

  Next, the operator similarly attaches the constituent member 200 to other adjacent blocks.

  Next, the operator 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 the adjacent blocks by a rail joint member (not shown). This completes all installation operations.

(7) Effect According to the present embodiment, the structural member 200 in the carry-in form is carried into the inclined section 12c of the truss 12 during the renewal construction of the escalator 10, and is transformed into the attached form, and then the beam member 220 and the cross beam member. The accurate shape is maintained with 216 and 218 attached, and the first support column 202 and the second support column 204 are fixed to the horizontal frame member 84 with bolts. Therefore, the mounting operation is simplified and it is not necessary to perform welding.

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

Example of change

  In the above-described embodiment, the pair of left and right first support columns 202 and the pair of left and right second support columns 204 are the constituent members 200 that are integrated by the cross beam members 216 and 218. The structure may be such that the constituent members 200 are respectively formed and attached to one side of each block of the truss 12.

  Moreover, although the said embodiment demonstrated the escalator 10 as a passenger conveyor, it may replace with this and may apply with the moving walk. In the case of a moving sidewalk, since there is no portion that changes from a horizontal portion to an inclined portion, the constituent members 200 can be attached in order for all spaces from the entrance 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, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
