DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator structure and an elevator construction method which are juxtaposed in a multi-story building.

[0002]

2. Description of the Related Art Among general multi-story buildings, there are many existing three- to five-story low-rise houses without an elevator. In particular, many of these low-rise apartments were constructed during the 1960s and 1940s, and their inhabitants are also aging. With the growing interest in barrier-free housing in recent years, There is a strong demand for additional elevators in homes.

[0003] As an elevator installed side by side with the above-mentioned existing low-rise houses, for example, Japanese Patent Application Laid-Open No. H11-256691 is disclosed.
Japanese Patent Application Laid-Open Publication No. H11-216,867 discloses a method for stacking and connecting a plurality of cylindrical members formed for each layer with a precast plate or a metal plate on a basic pit constructed at an installation site, and erecting an elevator shaft. I have. Most of the construction of the elevator, such as installation of elevators such as cages, ropes, rails, and the like in the elevator shaft, is performed at the installation site, including installation of the elevator shaft.

[0004]

However, when an elevator is installed side by side in an existing house, the construction must be carried out while securing the lives of the residents living in the existing house.
That is, in the elevator construction work, when working from the process of assembling the elevator shaft to the site, the construction period including the installation and removal of the scaffold is prolonged. Therefore, the residents are deprived of the living space around the site for a long period of time, and are forced to live in an inconvenient manner. Needless to say, it is better to shorten the construction period not only for existing houses but also for general construction work including new construction of general buildings.

Accordingly, the present invention has been made in view of the above-mentioned conventional problems, and shortens the construction period related to the on-site work of elevator construction work, and provides an elevator structure and an elevator construction method which are juxtaposed in a multi-story building. The purpose is to provide.

In order to achieve the above object, an elevator structure according to a first aspect of the present invention is an elevator structure installed in a multi-story building, in which the entire area in which a car moves up and down is one. An elevator shaft is integrally formed with a frame that is partitioned as an elevating space and a film body attached to the frame and covering the elevating space, and a cage and elevating means for elevating the cage are temporarily fixed in the elevating space. It is transported to the installation site.

That is, in this elevator, since the elevator shaft is composed of a frame and a membrane, even if the elevator shaft forms the entire elevating space as one space, it is formed by a conventional precast plate or the like. It can be significantly lighter than an elevator shaft. That is, since the weight of the elevator shaft is reduced, a cage and a lifting / lowering means are integrally provided in the elevator shaft, and the completed elevator can be easily carried into the installation place.

Therefore, the construction work at the installation site can be completed only by the installation process of installing the base pit and removing the temporary fixing, so that the work at the site can be reduced and the construction period can be greatly shortened. Furthermore, since the elevator shaft itself does not use concrete for its manufacture, there is no need for curing,
Also, since there is no work of assembling and removing the mold, it can be manufactured in a short time.

Further, the elevator shaft does not need to be constructed upright at the installation site in accordance with the building. Therefore, the elevator shaft can be built sideways at a different manufacturing site from the installation site. Therefore, it is not necessary to provide scaffolding not only at the elevator shaft installation site but also at the manufacturing site,
The installation and removal of the scaffold can be omitted in a short period of time. In addition, since there is no need to work at a high place, workability and worker safety are improved.

According to a second aspect of the present invention, there is provided a method for constructing an elevator which is juxtaposed in a multi-story building, wherein a frame for partitioning an entire area in which the cage is moved up and down as one elevating space is formed. An assembling step of attaching the membrane covering the elevating space to the frame to form an elevator shaft, installing a cage and elevating means of the cage in the elevating space, and assembling an elevator in advance, the cage and the elevating means, A carrying step of carrying the elevator temporarily fixed in the elevating space to the installation site by a transportation means, and suspending the elevator with a lifting device on a foundation pit juxtaposed to the multi-story building at the installation site. The method is characterized by comprising an installation step of lowering and installing and removing the temporary fixing.

That is, the elevator is provided with a cage and an elevating means in the elevator shaft in an assembling process before being carried into the site, and these are temporarily fixed and carried into the installation site. Only the installation process of installing and removing the temporary fixing can be completed. Therefore, work on site can be reduced, and the construction period can be significantly reduced.

Further, since the elevator shaft is made up of a frame and a membrane and is greatly reduced in weight, it is possible to assemble the elevator shaft as an integral structure, load it on a transportation means and easily carry it to the installation site. it can.

Further, since the elevator is reduced in weight, the elevator in a completed state in which the cage and the lifting / lowering means are incorporated can be lifted by a lifting device at the installation site, and it is extremely easy to just lower the elevator. The installation process can be completed quickly and in a short time.

Since the elevator 4 is set within the range in which it can be moved up and down, the elevator shaft 20a can be easily loaded into the installation site by being loaded on the trailer 52 or the like after being assembled as an integral structure.

In the elevator 10, since the frame 22 is exposed to the outside in a completed state, the elevator 10 can support the frame 22 at the time of loading and lifting, and can easily work. Further, since the membrane panel 28 forms an exterior wall, the membrane panel 28 may be exposed to the outside when it is carried into the installation site 58 from the factory 56, so that packaging for waterproofing or the like is simplified. Installation site 58
Waste material generated in the process can be reduced.

The film material 36b of the film body panel 28
Is the outer edge 2 of the frame 22 to which it is attached
It is arranged inside 4d. Therefore, elevator 1
When the elevator 10 is mounted, the membrane material 36b can be placed on the surface plate 18 that forms the support surface 18a of the elevator shaft 20, or even when the elevator 10 is placed directly on the bed of the trailer 52 when the elevator 10 is transported. , The frame 22 is arranged at a distance from the support surface 18a.
Therefore, when assembling or transporting the elevator 10,
Even if the elevator 10 is pulled sideways, the film material 36b forming the exterior wall is not damaged.

Further, since the weight of the elevator 10 is reduced, the completed elevator 10 incorporating the cage 14 and the lifting / lowering means can be lifted by the jib crane 54 at the installation site 58, and can be simply lowered. Thus, the installation process can be completed very easily and in a short time. In addition, since the elevator 10 is lightweight and easy to install, when the elevator 10 is no longer needed, it can be removed from the foundation pit 50 and moved to another installation site as it is, and can be easily reused. Can be.

In the above-described embodiment, the form in which the film material 36b is attached to the frame 22 as the panel-like film body panel 28 to cover the elevating space 20a has been described. However, the present invention is not limited to this, and the film material 36b may be directly attached to the frame. Alternatively, any other method may be used as long as it is mounted so as to cover the lifting space 20a.

In the above embodiment, the column member 2
