  Next, the sliding guide rail support structure 40 according to the present embodiment will be described with reference to FIGS. 4 to 8C.

  As shown in FIGS. 4 to 6, the guide rail support structure 40 includes a rail bracket 22 fixed to the hoistway wall 12 defining the hoistway 2, and a bracket piece 41 provided in contact with the rail bracket 22. And a pair of sliding guide rail clips 42 attached to the bracket piece 41. Among these, the front surface 22a of the rail bracket 22 is in contact with the back surface 21a of the guide rail 21 similarly to the guide rail support structure 20 shown in FIGS. That is, even when the guide rail support structure 20 is changed to the guide rail support structure 40 when the elevator is renewed, the rail bracket 22 shown in FIGS. 2 and 3 is used.

  The bracket piece 41 is in contact with the back surface 21 a of the guide rail 21. More specifically, the bracket piece 41 is provided above the fixed side portion 43 and the fixed side portion 43 that faces the back surface 22b of the rail bracket 22 (the surface on which the bracket piece 41 faces in FIG. 4). And a guide rail support portion 44. In the present embodiment, the front surface 43 a of the fixed side portion 43 is in contact (directly) with the rear surface 22 b of the rail bracket 22. The guide rail support portion 44 is disposed above the rail bracket 22, and the front surface 44 a of the guide rail support portion 44 is in contact with the back surface 21 a of the guide rail 21 (directly).

  As shown in FIGS. 7A and 7B, the fixed side portion 43 of the bracket piece 41 is provided with a through hole 45 through which a bolt 47 described later passes. The guide rail support portion 44 is provided with a through hole 46 through which a bolt 55 described later passes. The guide rail support portion 44 may be formed integrally with the fixed side portion 43, or may be formed separately and then coupled to the fixed side portion 43.

  The bracket piece 41 is attached to the rail bracket 22 with bolts 47, nuts 48, and washers 49.

  The bolt 47 includes a bolt body portion 50 that penetrates the rail bracket 22 and the bracket piece 41, and a bolt head portion 51 that is connected to the bolt body portion 50 and contacts the front surface 22 a of the rail bracket 22. As shown in FIGS. 4 and 5, the bolt body portion 50 of the bolt 47 passes through the through hole 30 of the rail bracket 22 and the through hole 45 of the bracket piece 41 (see FIG. 8A for both).

Yes. In the present embodiment, the bolt head 59 is formed in a rectangular parallelepiped shape. Accordingly, when the sliding guide rail clip 42 is attached to the bracket piece 41, the bolt head 59 is prevented from contacting the bent portion 54 of the sliding guide rail clip 42 and the bolt 55 from rotating. For this reason, the bolt 55 and the nut 56 can be tightened by rotating the nut 56 without holding the bolt 55. With such a shape of the bolt head 59, workability in a narrow place is improved.

  Next, the operation in the present embodiment having such a configuration will be described. Here, a renewal method of the guide rail support structure, that is, a method of changing from the fixed guide rail support structure 20 shown in FIGS. 2 and 3 to the sliding guide rail support structure 40 shown in FIGS. 4 to 6 will be described.

  First, in the fixed guide rail support structure 20 shown in FIGS. 2 and 3, the fixed guide rail clip 23 is removed from the rail bracket 22. In this case, the fixed guide rail clip 23 is removed by removing the bolt 24, the nut 25, and the washer 26.

  Next, as shown in FIGS. 8A and 8B, the bracket piece 41 is attached to the rail bracket 22. In this case, first, the guide rail support portion 44 of the bracket piece 41 is disposed above the rail bracket 22. More specifically, the bracket piece 41 is applied from the back surface 22b side of the rail bracket 22, and the fixed side portion 43 of the bracket piece 41 abuts on the back surface 22b of the rail bracket 22 to support the guide rail of the bracket piece 41. The portion 44 contacts the back surface 22b of the guide rail 21. Subsequently, the bolt body portion 50 of the bolt 47 passes through the through hole 30 of the rail bracket 22 and the through hole 45 of the bracket piece 41 and is tightened by the nut 48. At this time, the collar 52 is interposed between the bolt head 51 and the rail bracket 22, and the bolt head 51 passes through the through hole 53 of the collar 52.

  Next, as shown in FIG. 8C, the sliding guide rail clip 42 is attached to the bracket piece 41. In this case, first, the sliding guide rail clip 42 is disposed on the guide rail support portion 44 of the bracket piece 41. Subsequently, the bolt body portion 58 of the bolt 55 passes through the through hole 60 of the sliding guide rail clip 42 and the through hole 46 of the bracket piece 41 and is tightened by the nut 56. At this time, since the sliding-type guide rail clip 42 presses the guide rail 21 toward the bracket piece 41 is relatively weak, the guide rail 21 is positioned between the bracket piece 41 and the sliding guide rail clip 42 in the vertical direction. Is slidably held between the two.
