  Further, the main rope 5 extends downward at the tip of the other side of the weight-side top sheave 10, is wound around the sheave of the counterweight 3, extends upward at the tip, and the other end is on the weight side It is fixed to the main rope fixing base 11 and suspends a counterweight. The weight side main rope fixing base 11 is attached to the weight side top beam 12.

  The main rope fixing base side car guide rail 13 and the anti-main rope fixing base side car guide rail 14 are fixed on the car side pit base 15 installed on the bottom surface of the hoistway 1 and extend in the ascending / descending direction. 2 is guided in the up and down direction. The main rope fixing base side weight guide rail 16 and the anti-main rope fixing base side weight guide rail 17 are fixed on the weight side pit base 19 installed on the bottom surface of the hoistway 1 and extend in the ascending / descending direction. The weight 3 is guided in a direction opposite to the direction in which the car 2 is raised and lowered.

  Hereinafter, the installation procedure of the hoisting machine 4 will be described. First, the weight side pit base 19 is installed at a predetermined location. Next, an L-shaped support column fixing base 23 (23A and 23B) is arranged to be opposed to each other by a support column additional base bracket 19A and a support column base / guide rail bracket 19B attached in advance to the upper surface of the weight side pit base 19. Set up. At this time, the support column fixing bases 23A and 23B are arranged to face each other so that an opening is formed, and the opening is set to face the car 2 side.

  Next, the vicinity of the intermediate portion of the support column fixing bases 23A and 23B is fixed to the building by the support column base bracket 25 by welding or anchor bolts. Next, a supporting column beam 24 using H-shaped steel or U-shaped steel is installed on the upper surfaces of the supporting column fixing bases 23A and 23B. The support column beam 24 has a notch shape facing the car 2 side. The support column fixing bases 23A and 23B and the support column beam 24 have a gate shape after installation.

  Next, the main rope fixing base side weight guide rail 16 and the anti-main rope fixing base side weight guide rail 17 are erected on the upper surface of the weight side pit base 19, and the main rope fixing base side weight guide rail 16 is built into the building by the rail bracket 20. Secure with welding or anchor bolts. Next, the anti-main rope fixing base side weight guide rail 17 is fixed to the support post fixing base 23B and the support post beam 24 with a rail clip or the like.

  Next, the support column bracket 24A is attached to the upper surface of the support column beam 24, and the top beam support column 18 is erected on the upper side thereof. Next, the rail bracket 20 is fixed by welding to the fastener plate 21 of the building 22 located near the middle portion of the main rope fixing base side weight guide rail 16, the anti-main rope fixing base side weight guide rail 17 and the top beam support column 18, The main rope fixing base side weight guide rail 16, the anti-main rope fixing base side weight guide rail 17 and the top beam support column 18 are fixed by rail clips or the like.

  Next, the main rope fixing platform side weight guide rail 16, the anti-main rope fixing platform side weight guide rail 17 and the top beam support column 18 are located near the top of the car side top beam 9, the weight side top beam 12, and the car side top rope. The cars 8A and 8B and the weight side top sheave 10 are installed.

  The main rope fixing base side weight guide rail 16, the anti-main rope fixing base side weight guide rail 17 and the top beam support column 18, which have been described above, and the fastener plate 21 of the building 22 are fixed by welding via the rail bracket 20. Then, the installation work of the hoisting machine 4 is started. The hoisting machine 4 is unloaded by a lifting machine such as a chain block and transported toward the opening formed in the support column fixing bases 23A and 23B, and the upper part of the hoisting machine 4 and the lower part of the support column beam 24 are brought into contact with each other. And fix them with bolts.

  Next, the lower part fixing member 26 for the hoisting machine is installed on the lower side of the hoisting machine 4, and the hoisting machine 4 is fixed to the support pillar fixing bases 23A and 23B with bolts or the like. After fixing, the lifting machine such as the tune block is removed to complete the installation of the hoisting machine 4.

  When removing the hoisting machine 4 due to a failure of the hoisting machine 4, etc., it is possible to easily remove and reattach without disassembling other parts by performing the work in the reverse order to the installation work described above. Can do. The support column fixing bases 23A and 23B and the support column beam 24 can be self-supported by the weight side pit base 19 and the support column base bracket 25. Therefore, the hoisting machine 4 can be installed without any problem even if it is a method of standing from the upper side of the uppermost rail such as a construction method without a scaffold.

  As described above, according to the elevator apparatus 100 in the present embodiment, the support column beam 24 and the support column fixing base 23 are installed below the top beam support column 18, and the support column beam 24 and the support column fixing base 23 are installed. Since the portal shape for accommodating the hoisting machine 4 is formed, the hoisting machine 4 can be installed after the top beam support column 18 is erected. Further, when the hoist 4 is replaced at a later date, the top beam support column 18 is fixed by the support column beam 24, so that it is possible to save the trouble of preparing and fixing a fixing device. Therefore, the time spent for installing or replacing the hoisting machine 4 can be greatly shortened.
