BACKGROUND OF THE INVENTION
The present invention is an elevator construction method, and more particularly, to a construction method of the elevator in relation to the building itself and the elevator in constructing buildings.
[0002]
[Prior art]
Conventionally, elevators are well known as transport means for guiding passengers to each floor of a building. However, when building such an elevator, a technique for building an elevator after the building itself is completed (for example, (See Patent Document 1).
[0003]
3 and 4 show the elevator disclosed in Patent Document 1, FIG. 3 is an external perspective view in which a part of the elevator is broken, and FIG. 4 is an explanatory view showing the procedure of building the elevator.
[0004]
In FIG. 3, an elevator 10 is juxtaposed to an existing five-story existing low- and high-rise house 1 that forms a multi-story building, and is connected to a staircase 2 that connects the floors of the low- and high-rise house 1.
[0005]
The staircase 2 is provided with a refractive staircase, and a landing provided at an intermediate position with respect to each floor is arranged on the outer peripheral side of the middle- and low-rise housing 1, and the elevator 10 stops at the same height as this landing. Is set to
[0006]
The elevator 10 is mainly configured by an elevator shaft 11 having a quadrangular prism shape, a cage 12 that is lifted and lowered inside the elevator shaft 11, a lifting unit 13 such as a drive motor that lifts and lowers the cage 12, and a counterweight 14.
[0007]
The elevator shaft 11 is attached to the frame unit 16 and covers the lifting space 15. The frame unit 16 defines a lifting space 15 that covers the entire region from the lowest stop position to the highest stop position where the cage 12 can move up and down. A plurality of film body panels 17 forming an exterior wall are integrally formed to form a hollow column.
[0008]
The frame unit 16 includes four column members 18 made of large L-shaped steel and having the same length as the height of the elevating space 15. Further, a beam member 19 is interposed between the column members 18 at an appropriate interval along the longitudinal direction of the column member 18.
[0009]
As shown in FIG. 4A, the completed unit-shaped elevator 10 is in a state of being laid down by an overhead crane installed in the factory 3 after the lifting wire is hung on the frame unit 16 in the carry-in process. Then, it is lifted from the surface plate 9, moved as it is, loaded on the trailer 4 and carried into the installation site 5 as shown in FIG. At this time, temporary fixing of the movable parts such as the cage 12 and the counterweight 14 may be performed before the carry-in process, and may be performed after the assembly of the elevator shaft 11 is completed.
[0010]
On the other hand, as shown in FIG. 4C, a foundation pit 6 is constructed in advance on the installation site 5 in parallel with the existing building 1. The carried elevator 10 is suspended on the foundation pit 6 while being lifted upright from the trailer 4 by a jib crane 7 which is prepared at the installation site 5 and forms a lifting device.
[0011]
At this time, since the L-shaped steel forming the frame unit 16 can be used as a lifting jig, it is not necessary to temporarily install a jig, and the labor of attaching and detaching the jig can be saved, so that the work time can be saved. It can be shortened. And after inserting the lower end part of the column member 18 in the hole 8 currently formed in the foundation pit 6 and performing construction such as filling the hole 8 with concrete, the elevator 10 is installed. Then, the temporary fixing of the cage 12 and the counterweight 14 is removed, and the installation process is completed.

[0035]
Although the above embodiment has been described as a three-story building, only the number of elevator middle unit 22 increases according to the number of floors of the building, and the substantially connected structure is the same.
[0036]
The vertical steel member 41 and the horizontal steel member 42 are connected by welding fixing or bolt fastening fixing, and have an integral structure in which a brace (not shown) is attached for reinforcement along with the box-shaped twist correction of the elevator unit 40 as a whole. An elevator hoistway 47 is formed.
[0037]
In a state where the units 21, 22, and 23 are overlapped, the panel 48 that partitions the elevator hoistway 47 from the outside is fixed to the vertical steel member 41 and the horizontal steel member 42 via fixing members (not shown) such as bolts. . In addition, since the building itself is not completed in the state where the elevator unit 40 is superimposed, a waterproof sheet (not shown) for preventing rain is provided to prevent rainwater and the like from entering the elevator hoistway 47. Is also possible.
[0038]
The elevator control panel described above designates the number of floors that can be used (for example, the first floor as the lowest floor and the second floor as the intermediate floor) according to the construction status of the building, and the number of floors that cannot be used (for example, as the top floor) Electrical connection / disconnection is possible so as not to call or stop the elevator car 50 on the third floor).
[0039]
In addition, even if the elevator car 50 stops on a floor that has not been completed due to a malfunction or the like (for example, the third floor as the top floor), the door opening / closing vanes ( (Not shown) can be retrofitted.
[0040]
The floor concrete receiving frame member 25 and the panel 48 can be used as concrete retaining plates (not shown) on each floor and rooftop.
[0041]
As the building is constructed, concrete is driven in as the floor portions 31, 32, 33 of each floor, so that the elevator hoistway 47 (elevator unit 40) is fixed to the building.
[0042]
In this way, the elevator parts (elevator unit 40), which are unitized with the elevator hoistway 47, are carried in after the pit body 29 is completed before the building structure stands up, and are superposed by a crane. Due to this fixing, the elevator can be used even if the entire floor of the building is not completed, and it can also be used as a temporary elevator when building the building, thereby building a temporary elevator In addition, it is possible to contribute to shortening the construction period.
[0043]
In addition, a seat for rain prevention is installed in front of the landing on the floor where the building is not completed, and the elevator control panel has a setting for preventing the elevator door 51 from being opened and for preventing the landing call / car call from operating. Safety is ensured by having it.
[0044]
Furthermore, since the panel 48 as the outer wall of the elevator hoistway 47 can be used as a concrete stop plate for the floor or ceiling of each floor, simplification of work parts can be realized.
[0045]
The elevator hoistway 47 is fixed to the pit main body 29 when the pit main body 29 is completed. However, since the elevator hoistway 47 is fixed to the floor and ceiling of each floor as each floor of the building is completed, it is easy to secure the fixing strength. Can be maintained.
[0046]
In addition, since the elevator unit 40 is superimposed and fixed before the building is completed, it is not necessary to avoid the crane beam from interfering with the building, and a small, small-handed crane can be used. Combined with the availability of the building space, it becomes easy to secure the crane work space at the construction work site.
[0047]
Thus, in the elevator of the present invention, a long elevator straddling all the floors of the middle and low layers as shown in Patent Document 1 of the prior art is built in advance and transported to the construction site. The structure / construction method that superimposes the elevator unit 40 for each floor before the building construction is adopted without adopting the structure / construction method such as leaning, so that it can be used as a temporary elevator at the time of building construction. It can be easily adapted to different buildings.
[0048]
【The invention's effect】
In the elevator according to the present invention, since it is configured as described above, it is possible to make a building while using the elevator from an early stage before the building structure starts up. Not only can the construction period be shortened, but also temporary lifting equipment and a scaffold for it can be dispensed with.
