  The car frame 11 is assembled by preparing a plurality of members obtained by dividing the standing frames 23 and 24 in the longitudinal direction, and carrying the plurality of members into the hoistway 3 before assembling the standing frames 23 and 24. The plurality of members are connected and fixed together to form the standing frames 23 and 24.

  Specifically, the first member 31 of the pair of standing frames 23 and 24 is connected to the lower beam 21 by attaching the fasteners 42 to the long holes 44 and 47 outside the hoistway 3. And the 1st member 31 of a pair of standing frames 23 and 24 is stored in the state where it piled up mutually and was folded. As shown in FIG. 7, the lower beam 21 to which the first member 31 is connected is attached with a sling wire 54 at the lowest floor landing 5 a and is taken into the hoistway 3 by the lifting machine 53. That is, the first member 31 is coupled to the lower beam 21 and is carried into the hoistway 3 along with the lower beam 21 in a state of being folded with respect to the lower beam 21.

  After the lower beam 21 is taken into the hoistway 3, the lower beam 21 is fitted into the guide rail 4. At this time, a long steel material 55 that supports the lower beam 21 from below is provided on the lowermost floor surface 56 of the hoistway so that a car assembly operation is performed between the lower beam 21 and the lowermost floor surface 56 of the hoistway. The space for this is secured (see FIG. 10). An example of the steel material 55 is a long single pipe.

  After the lower beam 21 is taken into the hoistway 3, the first member 31 is raised in the vertical direction with respect to the lower beam 21 as shown in FIG. 8. After raising the first member 31, the fastener 42 is attached to the first fixing hole 41 to fix the first member 31 to the lower beam 21. Thereafter, the car floor member 26 constituting the floor portion of the car room 12 is attached to the lower beam 21.

  After attaching the car floor member 26 or before attaching the car floor member 26, the second member 32 of the pair of standing frames 23 and 24, the fastener 42 is connected to the elongated hole 44, and the outside of the hoistway 3. 47 is connected to the upper beam 22. And the 2nd member 32 of a pair of standing frames 23 and 24 is stored in the state where it piled up mutually and was folded. The upper beam 22 connected to the second member 32 is taken into the hoistway 3 by the lifting machine 53. That is, the second member 32 is connected to the upper beam 22 and is carried into the hoistway 3 along with the upper beam 22 in a state of being folded with respect to the upper beam 22.

  After the upper beam 22 is taken into the hoistway 3, the upper beam 22 is fitted into the guide rail 4. Thereafter, as shown in FIG. 9, the second member 32 is raised in a direction perpendicular to the upper beam 22. After raising the second member 32, the fastener 42 is attached to the first fixing hole 41, and the second member 32 is fixed to the upper beam 22.

  After raising the second member 32, the second end portion 34b of the second member 32 and the second end portion 34b of the first member 31 are connected and fixed to each other by the connecting steel plate 36 and the fastener 42. To do. Thereby, the standing frames 23 and 24 are formed. Thereafter, the car frame 11 of the elevator 2 is assembled through the centering of the car frame 11 and the installation of car surrounding equipment.

  When the car frame 11 is assembled, as shown in FIG. 11, the car room 12 is assembled, and then the elevator car 1 is assembled through various processes such as attachment of the car sheave 28.

  According to such a configuration, the assembly workability of the elevator car 1 can be improved. That is, when the standing frames 23 and 24 are formed of a plurality of members obtained by dividing the standing frames 23 and 24 in the longitudinal direction, and the plurality of members are connected and fixed to each other, the long standing frames 23 and 24 are formed. Before assembling, the plurality of members can be individually carried into the hoistway 3, and the plural members can be connected and fixed to each other in the hoistway 3 to form the standing frames 23 and 24.

  That is, the plurality of members can be connected to the lower beam 21 or the upper beam 22 before assembling the standing frames 23 and 24, and the standing frame is not limited by the length of the long standing frames 23 and 24. It is possible to perform a fixing operation between the vertical beams 23 and 24 and the lower beam 21 and a fixing operation between the standing frames 23 and 24 and the upper beam 22.

Then, the first member 31 can be carried into the hoistway 3 while being folded with respect to the lower beam 21, and the hoistway 3 with the second member 32 being folded with respect to the upper beam 22. Can be carried in. Thereby, the members 31 and 32 related to the standing frames 23 and 24 can be easily carried into the hoistway 3 along with the lower beam 21 and the upper beam 22, and the assembly workability of the elevator car 1 is improved.

  For example, in the present embodiment, the operation of fixing the first member 31 to the lower beam 21 with the first fixing hole 41 and the fastener 42 in the hoistway 3, and the second member 32 to the second fixing hole 43. And the work of fixing to the upper beam 22 by the fastener 42 is necessary, but when the first and second members 31 and 32 are connected to the lower beam 21 or the upper beam 22 in advance outside the hoistway 3, As a whole, the assembly workability of the elevator car 1 is improved.

  Although the embodiment in which the present invention is applied to the elevator car 1 in the new elevator has been described above, the present embodiment can also be used in the assembly of the new elevator car 1 after replacement in the elevator renewal process.

  FIG. 12 shows an example of the procedure for assembling the elevator car 1 using this embodiment in the elevator renewal process.
