By such fixing, the front side plate 71, the back side plate 72, the one side U-shaped angle 73, the other side U-shaped angle 74, the clip 75, and the clip 76 are integrated, and the integrated structure is obtained. The fixed structure is fixed to the pair of vertical frames 21a and 21b, and the integrated structure does not fall.

  As described above, the X-direction gap C (see FIG. 4) is a state in which the one and other U-shaped angles 73 and 74 are raised to the mounting posture, and the one and other U-shaped angles 73 and 74, The length is such that the front side plate 71 can be inserted between the strap-like member 52 for hanging the band. Therefore, the other side plate attaching step can be performed in a state where the back side plate 72 is suspended by the frame band attaching device 50, and the front side plate 71 is sandwiched between the band hanging string member 52 and the counterweight 10. The lower side of the front side plate 71 can be carried out in a state where it is supported by the band suspension string-like member 52 and the one and other side hooks 53 and 54. Therefore, the worker can perform the other side plate attaching step without lifting any part of the frame band 7 by the worker alone, and the labor for attaching the front side plate 71 is remarkably reduced.

  Subsequently, a hoist removal step, a second side plate attachment completion step, and a guide shoe attachment step are performed. In the hoisting machine removing step, one and the other side hooks 53 and 54 are detached from the one and the other side U-shaped angles 73 and 74, and the hooks 46a and 46b of the hoisting machine 51 are removed from the upper frame 22, thereby attaching the frame band. The device 50 is removed from the counterweight 10. Further, as shown in FIG. 6, in the other side plate attachment completion step, the front side plate 71 is fixed to the one side U-shaped angle 73 using bolts 77e and nuts, and the front side plate 71 is fixed using bolts 77f and nuts. The other side U-shaped angle 74 is fixed. Further, the front side plate 71 is fixed to the frame 21a using the bolt 77g and the clamp 75, and is fixed to the frame 21b using the bolt 77h and the clip 76. In the guide shoe attachment step, the guide shoes 5a and 5b are attached to predetermined positions of the weight frame 2 using bolts and nuts.

  The outline of the attachment of the frame band 7 to the counterweight 10 using the frame band attachment device 50 has been described above. The guide shoe attachment step is any later than when the lower ends of the one and other U-shaped angles 73 and 74 lifted by the frame band attachment device 50 exceed the upper ends of the attachment positions of the guide shoes 5a and 5b. It may be performed at the timing. In addition, the other side plate attachment completion step can be performed before the hoisting machine removal step, but the band suspension string-like member 52 obstructs the attachment of the bolt 77e, the bolt 77f, the bolt 77g, and the bolt 77h. Therefore, it is better to perform the other side plate attachment completion step after the hoist removal step. Further, the back side plate 72, the one side U-shaped angle 73, and the other side U-shaped angle 74 may be integrated on the upper side of the lower guide shoes 5a, 5b, and the guide shoes 5a, 5b may be removed. Attachment may be omitted. In the above description, the case where the one side plate is the back side plate 72 and the other side plate is the front side plate 71 has been described as an example. However, the one side plate is the front side plate and the other side plate is the back side. It may be a plate.

  According to the above embodiment, the attachment portion 42 of the hoisting machine 51 is attached to the upper frame 22 of the counterweight 10, and the Y direction one side portion (one side U-shaped angle 73) of the frame band 7 is attached to the one side hook. 53, and the other side portion of the frame band 7 in the Y direction (the other side U-shaped angle 74) is locked to the other side hook 54, and then the string-like member 41 is simply lifted by the hoist 51. The back side plate 72 located on one side in the Z direction in the frame band 7 can be pulled up to the frame band mounting height. And while the back side board 72 is hold | maintained by the frame band attachment height with the frame band attachment apparatus 50, while being able to integrate with the front side board 71 back side board 72, the front side board 71 can be attached to the counterweight 10. Therefore, it is not necessary for the worker to assemble the frame band 7 in a state where both the front side plate 71 and the back side plate 72, which are heavy objects, are held in the air. Installation work can be performed safely.

  In addition, one end of the string-like member 41 of the hoist 51 is fixed to the ring-shaped member 55, and the one side hook 53 is fixed to one end of the band-suspending string-like member 52 that passes through the ring-shaped member 55. The other side hook 54 is fixed to the other end portion of the band suspension string-like member 52. Therefore, the frame band attaching device 50 can be configured simply and inexpensively. In addition, since the structure other than the hoisting machine 51 is simple and compact, the frame band attaching device 50 can be easily transported without taking up space.

  Furthermore, since the attaching portion 42 of the hoist 51 is attached to the upper frame 22 of the counterweight 10, the frame band attaching device 50 can be easily attached to the elevator. Further, while the frame band partial ascending step is being performed, the back side plate 72 moves to the counterweight 10 so that the back side plate 72 moves away from the back side plate 72 or the counterweight 10 in the X direction as it goes upward in the Z direction. It is leaning against. Therefore, while the frame band partial ascending step is being performed, the back side plate 72 is not caught on the contact portion 98 (see FIG. 4) of the weight piece 3, and the frame band partial ascending step is smoothly performed. Can do.
