The component 25 attached to the attachment portion 47 is not limited to this. The component 25 may be a flat / thin hoisting machine (motor), a seismometer, a control panel, or other devices.

  Then, with reference to FIG. 2 etc., an example of the assembly method of the elevator 11 of this embodiment is demonstrated.

  First, the support member 17 (the first portion 31 and the second portion 32) is fixed to one place of the wall portion 13 of the building by an anchor bolt 24, welding, or the like. The first portion 31 and the second portion 32 are fixed by, for example, a fixture 36 or welding. Subsequently, the shaft portion 41 of the mounting member 23 is passed through the mounting hole 35 of the support member 17. Then, the second reinforcing member 22 is hooked on the shaft portion 41 and positioned so as to pass through the second hole 46 of the second reinforcing member 22 with respect to the shaft portion 41. Further, the first hole 44 of the first reinforcing member 21 is passed through the shaft 41 so that the first reinforcing member 21 overlaps the upper side of the second reinforcing member 22. Thus, the first reinforcing member 21 is hooked and positioned with respect to the shaft portion 41. In the present embodiment, for example, two first reinforcing members 21 are used, but three or more may be used, or one may be used.

  Subsequently, the main rail 16 is erected along the first reinforcing member 21. Then, with the main rail 16 supported by the operator, the shaft portion 41 is passed through the third hole 43A of the holding portion 43 (clip) with respect to the shaft portion 41 so that the fixing portion 42 overlaps from the upper side of the holding portion 43. The fixing portion 42 is fixed (fastened) to 41. At this time, the main rail 16 is held between the first reinforcing member 21 and the holding portion 43 (see FIGS. 2 and 4).

  Further, the support member 17 (the first portion 31 and the second portion 32) is fixed to other portions of the wall portion 13 of the building by anchor bolts 24 or the like. And the operation | work which fixes the 1st reinforcement member 21, the 2nd reinforcement member 22, and the main rail 16 to the support member 17 with the attachment member 23 is repeated in the procedure similar to the above. Even at positions between the support members 17, the first reinforcing member 21, the second reinforcing member 22, and the main rail 16 are fixed using fixing means 48 (for example, bolts, nuts, clips, and the like). Thus, the assembly process (attachment process) around the main rail 16 of the elevator 11 is completed.

  According to the first embodiment, the elevator 11 has a rail, a plurality of plate-like first reinforcing members 21 provided adjacent to the rail, and protrudes on the opposite side of the rail and extends the rail. A plate-like second reinforcing member 22 provided adjacent to the first reinforcing member 21, the rail, the first reinforcing member 21, and the second reinforcing member. A supporting member 17 that supports the member 22 and is fixed to the building side, and an attachment member 23 that attaches the rail, the first reinforcing member 21, and the second reinforcing member 22 to the supporting member 17 are provided.

  According to this configuration, since the reinforcing member includes the plurality of first reinforcing members 21 and the second reinforcing member 22, the plurality of first reinforcing members 21 and the second reinforcing member 22 are individually attached to the support member 17. Can do. Thereby, the weight of the reinforcing member can be distributed to the plurality of reinforcing members. In general, the safety standard stipulates that a lifting machine is used for installing a member having a weight exceeding 20 kg. In the conventional reinforcing member, since the weight per unit length is heavy and the total weight may exceed 20 kg, a lifting machine is essential. According to the said structure, the weight of each reinforcement member can be reduced and a lifting machine can be made unnecessary for work. For this reason, it is particularly useful when there is no place to suspend the lifting machine in the hoistway 12 when the elevator is renewed. Moreover, since the weight of each reinforcing member can be reduced, the burden on the operator can be reduced and the work can be performed safely.

  Further, since the first reinforcing member 21 and the second reinforcing member 22 are formed in a plate shape, a laser or the like is not required for cutting them, and they can be cut with a lathe, reducing the processing cost and reducing the cost. it can. Furthermore, since the protrusion part 45 is provided in the 2nd reinforcement member 22, the section modulus in the thickness direction of the 2nd reinforcement member 22 can be enlarged. Accordingly, the second reinforcing member 22 can be strengthened against the bending load in the thickness direction, and it is possible to easily meet the legal requirement that the deformation of the main rail 16 is within a predetermined range (for example, within 5 mm).

  Conventionally, the support member 17 is disposed at a position between the thick plate-like reinforcement plates, and the rail is directly fixed to the support member 17. However, according to the above configuration, the first reinforcement member 21 and the first reinforcement member 21 are arranged. 2 The support member 17 can be arranged at an arbitrary position on the reinforcing member 22. For this reason, the freedom degree at the time of installation in the field can be improved, such as changing the position of the support member 17 according to the situation of a building etc. suitably. Therefore, not only when installing new elevators, but also when renewing existing elevators, the position and number of support members 17 are changed in accordance with the situation of the building, improving the degree of freedom during assembly (installation). Workability can be improved.

  Furthermore, the required strength can be ensured by changing the number of the first reinforcing members 21 according to the required strength that varies depending on the size of the elevator 11 and the length of the hoistway 12. As a result, the versatility of the reinforcing member can be improved, such as being able to cope with elevators 11 of various sizes and lengths.

  The second reinforcing member 22 has a hat shape in cross section. According to this configuration, it is possible to prevent the weight of the second reinforcing member 22 from increasing due to the provision of the protrusion 45 while ensuring the rigidity of the second reinforcing member 22.

  The support member 17 is provided on both sides of the recess 33 that can store the protrusion 45 and the recess 33 therebetween, and extends along the direction in which the rail extends, and the rail, the first reinforcing member 21, and the second And a support portion 34 that supports the reinforcing member 22. According to this configuration, even if the second reinforcing member 22 has a structure having the protruding portion 45, the supporting portion 34, the rail, the first reinforcing member 21, and the second reinforcing member 22 are fastened together by the mounting member 23 ( It is possible to easily realize a structure that is fixed together. As a result, the number of mounting members 23 can be substantially reduced, the structure can be simplified, and the number of workers on site can be reduced.

  The protrusion 45 is provided with a plurality of attachment portions 47 to which the component 25 can be attached. Usually, various parts 25 may be arranged between the rail and the wall 13 of the building. According to said structure, it can prevent that the components 25 which were arrange | positioned conventionally cannot be arrange | positioned by providing the protrusion part 45, for example. Moreover, since the attachment part 47 is provided with two or more, the component 25 can be suitably attached according to the condition of a building.

  In the method of assembling the elevator 11 according to this embodiment, the support member 17 is fixed to the building side, the shaft portion 41 of the mounting member 23 is passed through the mounting hole 35 of the support member 17, and the second reinforcing member 22 is connected to the shaft portion 41. The first reinforcing member 21 is passed through the first hole 44 of the first reinforcing member 21 and attached to the shaft 41 so that the first reinforcing member 21 overlaps the second reinforcing member 22. While passing the 3rd hole 43A of the holding part 43 of the member 23, the said rail is hold | maintained between the holding part 43 and the 1st reinforcement member 21, and the fixing | fixed part 42 of the attachment member 23 overlaps with the holding part 43 The fixing portion 42 is fixed to the shaft portion 41.

  According to this configuration, the weight of the reinforcing member can be distributed to the plurality of first reinforcing members 21 and the second reinforcing member 22. Moreover, according to the said structure, the weight of each reinforcement member can be reduced and a lifting machine can be made unnecessary for work. As a result, for example, there may be no need to carry the lifting machine into the hoistway 12 or to attach the lifting machine to the upper part of the hoistway 12, and work efficiency can be improved. Moreover, since the weight of each reinforcement member can be reduced, the burden on the operator can be reduced and the work can be performed safely.

  Furthermore, the first reinforcing member 21 and the second reinforcing member 22 can be hung on the shaft portion 41 by being hooked with the first reinforcing member 21 and the second reinforcing member 22 to be positioned (temporarily fixed). The operator does not need to hold the first reinforcing member 21 and the second reinforcing member 22, and the working efficiency can be improved. Furthermore, since the supporting member 17, the first reinforcing member 21, the second reinforcing member 22, and the rail can be fixed together (fixed together) with the mounting member 23, the fixing portion is fixed as compared with the case where they are fixed individually. The number of (attachment members) can be reduced to reduce the number of man-hours on site.
