However, such a conventional building has the following problems because the elevator is installed in a building of a specified size. That is, in the elevator, the size of the elevator is limited by the size of the building, and there is a problem that the room becomes narrow if an attempt is made to increase the space for the elevator. In addition, when a car, a guide rail, a driving device, a pulley, or the like is mounted on a building at a site, there is a problem that the number of local steps and transportation costs are increased.

Accordingly, the present invention focuses on the above-mentioned problems, and provides a unit building which can take up a large space for an elevator and reduce man-hours and costs on site.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and comprises a plurality of building units each having a floor and walls erected on the side edges thereof. Auxiliary unit for the overhanging part which is vertically continuous is attached to a part of the wall of the building unit on the upper floor and the lower floor, and a ventilation opening is provided in the building unit and the floor of the auxiliary unit, and a ventilation opening is provided. A guide rail is provided that straddles the upper and lower floors through the section, and an elevator car is vertically movably mounted along the guide rail.

[0006] In the present invention, the elevator is attached to the opening of the stairwell by arranging an elevator frame composed of pillars at four corners and a frame material connecting the pillars on the upper and lower floors through the stairwell, and Attach the guide rails on both sides of the car, install the drive unit and pulley on the side of the overhanging auxiliary unit, and make the elevator car move up and down along the guide rails. preferable.

(Operation) In the unit building according to the present invention, an auxiliary unit for a projecting part which is vertically connected to a part of the wall of the building unit on the upper floor and the lower floor is attached to the building unit and the floor of the auxiliary unit. An opening is provided, and a guide rail that extends over the upper and lower floors through the atrium opening is provided, and along this guide rail, the elevator car is mounted so as to be able to move up and down, so that it does not straddle the adjacent building unit In addition, an auxiliary unit for the overhanging part is added, and the pulleys and the driving device of the elevator are attached to the opening of the atrium, so that the space of the elevator in the space of the atrium can be widened. Can be installed.

In a factory, an elevator car or a guide rail is mounted on the building side, and a drive device or a pulley is mounted on the overhanging auxiliary unit side, or is temporarily mounted, so that the number of installation steps on site can be reduced. The cost of transportation to the site can be significantly reduced.
