Description

  The present invention relates to an elevator apparatus that can be widely used from a low-middle layer to a high-rise building, and an installation method for the elevator apparatus.

  In recent years, in an elevator apparatus, space saving has been achieved, and various elevator apparatuses having no machine room have been developed.

  Conventionally, as shown in FIGS. 11 and 12, for example, a car 22 that moves up and down along a guide rail 21 for a car, and a counterweight 24 that goes up and down along a guide rail 23 for a counterweight, as shown in FIGS. In the elevator apparatus comprising a car 22 and a hoisting machine 26 around which a main rope 25 for raising and lowering the counterweight 24 is wound, the hoisting machine 26 is located below the hoistway 27 and the elevator 22 is moved up and down. There is a space between the space by the projection surface and the wall of the hoistway 27 fixed to the mounting member 28 fixed to the car guide rail 21 and the counterweight guide rail 23. The mounting member 28 includes an upper support beam 29, a lower support beam 30, and a base 31 fixed to the upper support beam 29 and the lower support beam 30 on the upper and lower sides, respectively. One side of the support beam 30 is clipped to the car guide rail 21 and the other side is clipped to the counterweight guide rail 23 (Patent Document 1).

  In order to install this type of elevator, the current construction method is a scaffolding method in which a scaffold is assembled or a gondola method in which a gondola is used.

  In the scaffold construction method, the elevator is assembled by assembling the scaffold from the lower part to the upper part on the elevator hoistway. In the gondola method, the gondola is suspended from a ceiling hook provided at the elevator hoistway top and the gondola is suspended to perform the elevator installation work.

In addition, during construction of a building, a gondola in the above-mentioned gondola method is used for transporting workers and various work equipment. However, when transporting large work equipment, etc., the outer wall of the building Large lifts installed in are used.

  Since the conventional elevator apparatus supports the load of the hoisting machine 26 by the passenger guide rail 21 and the counterweight guide rail 23, the load acting on each guide rail is reduced. Can be used with relatively low strength, or no reinforcement is required.

  However, in the above-described conventional elevator device, a relatively low strength guide rail can be used, or even if reinforcement is not necessary, the load of the hoisting machine 26 is supported by the guide rail. A guide rail with relatively low strength can only be used.

  Furthermore, in the above-mentioned conventional elevator apparatus installation method, in the case of the scaffold method, it takes a lot of wasteful costs and labors such as loading and assembling of scaffold materials and dismantling, and there are many problems in workability and safety. There are many dangers such as the fall disaster, and prompt improvement of countermeasures is desired. Even in the case of the gondola method, there are problems such as wasteful costs and labor such as loading and assembling and dismantling of the gondola, and high costs such as round-trip transportation costs between the storage warehouse and the construction site. In the case of the gondola construction method, the workability and safety are better than the scaffold construction method, but the gondola may shake or tilt, and there have been reported cases where a gondola fall accident has occurred due to a functional problem of the fall prevention device. However, it is generally not safer than the scaffold method.

  In this step, the car guide rail 3 and the counterweight guide rail 4 are centered on the basis of a piano wire or the like, and the lower ends of the car guide rail 3 and the counterweight guide rail 4 are respectively set in the second step. Align and add to the upper ends of the car guide rail 3 and the counterweight guide rail 4 laid in step 3. The upper and lower parts of the car guide rail 3 and the counterweight guide rail 4 are fixed with fixing brackets 13 or the like. Fix to the side wall of the hoistway 2. In this case, the worker rides on the car frame 17 to work, and this car frame 17 is a framework of the elevator car 5 that operates normally, and the car 5 is overspeeded. In addition, a governor for operating the emergency stop device is provided, and a shock absorber 15 for the car 5 is provided at the lower end portion of the car guide rail 3. The device works and is excellent in safety.

  As an eighth step, while the car frame 17 is raised by the hoisting means 8, a plurality of intermediate portions of the added car guide rail 3 and counterweight guide rail 4 are fixed to the side wall of the hoistway 2.

  In this process, the added car guide rail 3 and counterweight guide rail 4 are firmly fixed to the side wall of the hoistway 2, and an operator rides on the car frame 14 to While raising the installation car frame 14 by the hoisting means 8, a plurality of intermediate portions of the added car guide rail 3 and counterweight guide rail 4 are moved up and down by the fixing bracket 13 in order from the bottom to the top. Fix to the side wall of the road 2. In this case as well, as described above, the car frame 17 on which the operator rides is provided with a governor for operating the emergency stop device when the elevator car 5 operating normally is in an overspeed state. Furthermore, since the shock absorber 15 of the car 5 is provided at the lower end of the car guide rail 3, these devices also work in the car frame 17 and are excellent in safety. .

  Then, the same processes from the sixth process to the eighth process are repeated until the machine beam 9 provided with the hoisting means 8 can be installed on the hoistway 2 at the top of the building. In the first step, when the machine beam 9 provided with the hoisting means 8 is installed on the uppermost part of the hoistway 2, it is necessary to repeat the same steps from the sixth step to the eighth step. Absent.

  Further, as the next step, while raising the car frame 17 by the hoisting means 8, the separation walls 18 serving as the side walls of the hoistway 2 are respectively connected to the boundaries of the hoistway 2 adjacent to the two or more rows. Lay in order from the bottom of 2 to the top.

In this process, when an isolation wall 18 serving as a side wall of the hoistway 2 is laid on the boundary between the hoistways 2 adjacent to each other in two or more rows, an operator gets on the car frame 17 to While raising the frame 17 by the hoisting means 8, the isolation walls 18 serving as the side walls of the hoistway 2 are laid in order from the lower side to the upper side of the hoistway 2 at the boundary between the two or more adjacent hoistways 2. .

Then, as a final process, the car frame 17 is replaced with the elevator car 5.

  In this process, the car frame 17 used for transporting a large work equipment or the like during the construction of the building is removed from the main rope 7 of the hoisting means 8, and in each hoistway 2 of the building, An elevator car 5 that will operate normally in the future is suspended from one end of the main rope 7 of the hoisting means 8. In this case, the counterweight 6 is kept suspended from the other end of the main rope 7 of the hoisting means 8.

  Therefore, the elevator apparatus installation method of the present invention having the steps as described above can be used for transporting large work equipment and the like during the construction of the building, and the safety of the installation work. The installation cost is not increased.
