DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an elevator tower for constructing a building on an outer floor of a middle-floor building so that the building can go up and down to a target floor.

[0002]

2. Description of the Related Art In recent years, there are many existing middle-rise apartments and the like in which an elevator is not installed. In recent years, there is a demand for installing an elevator in an existing middle-rise apartment or the like. In order to install an elevator in an existing middle-rise apartment or the like, it is necessary to install the elevator with little modification to the existing building because residents live in the existing building. For this reason, an elevator tower is formed outside the existing building.

[0003] In order to form an elevator tower outside the existing building, steel towers are assembled on site to form the elevator tower, and furthermore, when the elevator tower is formed at the site, doorways are formed in the tower. At the same time, a dedicated access passage connecting the entrance of the elevator tower, the landing of the stairs of the existing building, the outer corridor and the entrance of the elevator tower was formed on site.

[0004] In the above-mentioned conventional example, it is necessary to assemble a steel frame on site to form an elevator tower, and to form a communication passage on site. High costs and long construction times were not desirable given that residents lived in existing buildings.

By the way, when a building is newly constructed, elevator tower units are simply stacked up and down in an elevator installation space in the building to form an elevator hoistway.
It is known that a platform such as a corridor is formed on site at each floor of the building, but at the time of this new construction, the technology of stacking elevator tower units in the building to form an elevator hoistway is used on the outside of the building. Although it is also conceivable to apply it to form an elevator tower, it is possible to simplify the on-site construction and shorten the construction period by stacking the elevator tower units to form an elevator hoistway. However, even in this case, it is still necessary to form a dedicated communication passage connecting the entrance of the elevator tower, the landing of the stairs of the existing building and the outer corridor with the entrance of the elevator tower, still on the site, Since a dedicated communication passage is constructed at the site, there is a problem that the number of site works increases, the cost increases, and the construction period becomes longer. . In particular, it is necessary to make a scaffold at the site to form a dedicated communication passage at the site, and there is a problem that the finish of the dedicated communication passage is not uniform due to variations in construction at the site.

In any of the above cases, a communication passage is formed at the site. However, only handrails are formed on both sides of the communication passage at the site. There is a problem that the neighborhood is exposed to the weather, making it difficult to get on and off the elevator car easily.In addition, the opening and closing door provided at the entrance and exit, the opening and closing mechanism of the opening and closing, various electric equipment and wiring etc. There is a problem that it is adversely affected by the weather. For this reason, it is necessary to separately form a windproof rain screen on site to prevent the entrance and exit of the elevator tower and its vicinity from being exposed to wind and rain, and when such a windproof rain screen is formed on site, In addition, site construction has increased,
There is a problem that the construction period is longer.

[0007] When an elevator tower is formed outside the building, electric wiring runs up and down in an elevator hoistway for raising and lowering the car, and the electric wiring does not hinder the raising and lowering of the car. However, it is not preferable to pass electric wiring up and down in the elevator hoistway where the car moves up and down in consideration of an emergency.

[0008]
