2. Description of the Related Art In recent years, the development of high-rise building construction technology has been remarkable, and along with this, in order to improve the efficiency of construction work, the machine room is gradually changed in accordance with the process of the construction work moving from the lower level to the upper level. Construction elevators that are temporarily installed and operate elevator cars in this temporary machine room to perform work such as hoistways are often used.

FIG. 5 shows, for example, Japanese Patent Publication No. 59-35821.
FIG. 3 is a cross-sectional view showing a conventional installation method for a construction elevator, which is disclosed in Japanese Patent Publication, in which (a) shows a state before a machine room is raised,
(B) shows a state after the machine room is raised.

In the figure, a rope feeding device 3, a rope winding device 4, a hoisting device 5 and a deflecting wheel 6 are provided in a temporary machine room 2 supported on a building receiving beam 1, and a hoisting device 6 is lifted up. A hook 7 is provided. Here, the rope paying-out device 3 uses the rope 8 during the service operation of the elevator.
Is held to prevent the rope 8 from being fed out, and when the machine room 2 is moved upward, the holding force is relaxed so that the rope 8 can be fed out. The rope 8 is from the rope winding device 4,
Sheave 1 of counterweight 11 through rope feeding device 3
2, the deflector wheel 6, the hoisting device 5, and the sheave 10 of the elevator car 9, and the other end reaches the machine room 2.
Reference numeral 13 is a buffer.

In the above construction, when the construction work progresses and the machine room 2 is raised by the distance A, first, the elevator car 9 is placed in the lower part of the machine room 2 as shown in FIG. 14 and so on, while the counterweight 11 is lowered to the bottom of the pit and fixed.

Next, the rope feeding device 3 is adjusted to loosen the holding force of the rope 8 and the rope winding device 4 is made rotatable. After that, the machine room 2 and the elevator car 9 suspended from the machine room 2 are lifted by the tower crane 15 and the like via the lifting hooks 7. In this case, if the holding force of the rope 8 by the rope unwinding device 3 is kept at a value such that the rope 8 does not drop under its own weight, the rope 8 will be placed in the machine It will be automatically paid out according to the movement of 2. After the machine room 2 is moved, as shown in FIG. 5B, the machine room 2 is fixed to the building by the receiving beam 16, and then,
The rope feeding device 3 is restored, the rope 8 is held, the chain block 14 is gradually loosened and removed, and the work of moving the machine room 2 is completed.

The temporary machine room 2 had to be lifted and moved and installed by using a tower crane 15. Further, since the upper part of the building is not formed, it is necessary to take measures against rainwater, and further, after the installation work is completed, it has to be dismantled and removed, which requires a lot of work time. Then, when the machine room 2 is moved using the tower crane 15, the movement of the machine room 2 and the rope 8
The tower crane 15 for construction generally has a high hoisting speed at this time, and it is difficult for the operator of the tower crane 15 to directly check the feeding condition of the rope 8. There is a possibility that the rope 8 is restrained and the rope 8 is restrained, or the rope 8 is unwound more than necessary and may be wound around other equipment, which is extremely dangerous and difficult. It was

In view of the above, the present invention allows the elevator installation work to be performed safely and in a short time while sequentially moving the machine room or the like in accordance with the construction process, thus eliminating the need for assembling and disassembling temporary materials. It is an object to provide a method for installing the elevator.

The elevator installation work will be suspended while the elevator is being used as a construction elevator.

Then, the core structure 18 and the building structure 2
When the assembly of the predetermined floor of No. 1 is completed, the use of the elevator is temporarily stopped, and this time, the core structure 17 and the truss structure 20 are moved, that is, the preparation for pushing up the predetermined floor is performed. On the other hand, the elevator side also prepares for the extension work upward.

In preparation for pushing up on the elevator side,
First, the elevator car 30 is stopped at the top floor of the completed car, and the emergency stop device 32 is activated to operate the elevator car 30.
Of the rope, the hanging weight 31 is hung by the chain block 33, etc., and the rope 36 is replaced according to the stroke of the newly formed hoistway 27, or the rope wound around the rope feeding device 35. Take out 36. This completes the preparation work on the elevator side.

When the preparatory work is completed, the core structure 17 and the truss structure 20 are again pushed up by the jack-up device 19 and the jack-up device 22, respectively.
The state immediately after the core structure 17 is pushed up is shown in FIG. After pushing up the core structure 17, as shown in FIG.

Further, the building structure 21 is assembled below the truss structure 20. At the same time, the car rail 28, the weight rail 29, the hall door device 34, and the hoistway equipment are installed also on the elevator side.
And when these installations are completed, like the above,
Use the elevator for construction.

In this way, the building is completed by repeating these operations in sequence, and the elevator installation work is also completed. The installed elevator can be immediately used for construction without dismantling the machine room 24, and can be used as a normal elevator.

As described above, in the elevator installation method of the above-described embodiment, the uppermost core structure 17 assembled first is attached to the upper part of the core structure 18 by the jack-up device 19 as a pushing-up means. The core structure assembling step of sequentially assembling the core structures 18 from the lower layer to the upper layer while pushing up to the upper layer, and with the assembling of the core structures 18, the truss structure 20 forming the uppermost floor is attached to the core structures 18. Jack-up device 2 as push-up means attached to the
2 is pushed upward by 2 while the building structure 21 is sequentially arranged from the lower layer to the upper layer below the truss structure 20.
The building structure assembling process is performed during the building assembly process, and when the uppermost core structure 17 is completely assembled, the hoisting machine, which is a drive-related device for the elevator, is installed inside the core structure 17. 25, control panel 26,
A drive-related device installation step of installing a speed governor, a hoistway formation step of forming an elevator hoistway 27 inside the core structure 18, and the core structure 18 having 3 to 4 sections, that is, 9 to 12 When the floor structure is assembled, the elevator car 30 and the suspension weight 31, which are the lifts, are installed in the hoistway 27, and an elevator installation step, and the core structure 18 is assembled every predetermined floor. In the hoistway 27, an elevator body guide member installation step of connecting and installing a car rail 28 and a weight rail 29, which are elevator body guide members, is installed.

Therefore, according to the above-described embodiment, when the core structure 17 which is the uppermost part of the building is first assembled, the elevator drive-related equipment is installed therein,
While the core structure 18 is being gradually assembled from the lower layer to the upper layer, the elevator hoistway 27, the hoist body,
By sequentially installing the elevating / lowering body guide member, it is possible to carry the building equipment and the worker by utilizing them. When the building is assembled to the top floor, the installation of the elevator is completed, and then the elevator can be immediately used for construction work without dismantling the machine room 24. Further, since the uppermost core structure 17 has a permanently installed roof, measures against rainwater are unnecessary. Furthermore, since the tower crane is not used to move the core structure 17, it is conventionally difficult for the operator of the tower crane to directly check the rope feeding condition, so that some abnormality occurs in the rope feeding device. As a result, there is no risk of the rope being restrained, or the rope being unwound more than necessary and being wound around other equipment, and the work can be performed safely.

By the way, in the installation of the elevator of the above-mentioned embodiment, when the assembly of the core structure 17 is completed, the drive-related equipment of the elevator is installed, and when the core structure 18 is assembled for a predetermined floor, the core structure 18 is installed. The elevating body is installed in the hoistway 27 formed in the structure 18, and the core structure 1
Every time 8 is assembled for a predetermined floor, an elevating body guide member, a landing door device 34, etc. are installed in the hoistway, but when the present invention is carried out, the present invention is not necessarily limited to this. If the elevator can be installed in conformity with the building work of a building that is sequentially assembled from the lower layer to the upper layer, the contents of the elevator installation work corresponding to each building process can be appropriately changed. For example, the control panel 26 in the machine room 24 may be installed not when the core structure 17 has been assembled but at a stage where the core structure 18 has been assembled to some extent, and the hall door device 34 may be installed in the core structure. Although 18 is installed at the stage where 3 or 4 sections have been assembled,
It may be installed for each one-section assembly.
