Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for exchanging a cartridge for a building unit, which can be used for a cartridge exchanging operation for a unit house constructed by arranging and stacking box-shaped building units.

[0002]

2. Description of the Related Art Conventionally, in a residential building or the like, a unit type prefabricated building constructed by arranging and stacking box-shaped building units has been widely used. In such a unit type building, since the structure, exterior, interior equipment, etc. are factory-installed for each building unit, only simple work such as joining and assembling each building unit and mutual pipe connection is done on site. This has the advantage that the construction period can be shortened and costs can be reduced.

Incidentally, even in the unit type building as described above, it is necessary to refurbish the inside due to, for example, changes in the family structure of residents or deterioration of interior equipment. At this time, in the case of a small-scale remodeling, as in conventional architecture, the method of removing the interior and equipment in each building unit and installing new equipment is adopted. However, in the method of renovating only the interior equipment, since the worker sequentially renovates the building, the advantage of being a unit type construction is not utilized, and the number of construction days becomes long as in the conventional construction method.

On the other hand, in the case of a large-scale remodeling, a method of removing the building unit itself which constitutes the unit type building and replacing it with another building unit may be adopted. However, in the method of replacing each unit, although the work can be performed quickly by taking advantage of the unit-type construction, it is wasteful because the other parts in the unit are collectively replaced. In addition, since the structure of the building unit to be replaced is temporarily removed, the structure of the building is affected, and the construction is inevitable.

To address these problems, the applicant of the present invention has proposed a cartridge-type building unit that enables quick and easy internal refurbishment. This cartridge type building unit has a frame that is assembled in a box shape
An outer wall panel that is detachably installed on one side surface of the frame, a cartridge that has predetermined interior equipment and can be stored in the frame, and the outer wall panel that holds the cartridge at a predetermined position in the frame. A holding rail that can be guided toward the side is provided.

In such a cartridge-type building unit, the outer wall panel facing the cartridge to be refurbished is removed, the cartridge to be refurbished is pulled out, a new cartridge is inserted in the removed mark, and the outer wall previously removed. Refitting the panel will result in a refurbishment within the building unit. Therefore, it is possible to perform a quick refurbishment work by replacing the cartridge in which the interior equipment has been installed in advance, and since there is no waste because only the cartridgeized part is replaced, and the structure of the building unit The work can be simplified because no modification is required.

Here, the cartridge is installed in each compartment having a clear function, such as a bathroom or a toilet, or collectively includes functional equipment such as a kitchen unit, a washbasin unit, and an interior air-conditioning unit for a living room. It is installed so that it can be accommodated. Further, the cartridge may occupy substantially the entire building unit, may occupy a part of the building unit, or may be set so that one or more cartridges can be accommodated in the building unit.

[0008]

By the way, in the above-mentioned cartridge type building unit, when replacing the cartridge, it is necessary to pull out or feed in while holding the cartridge outside the building unit.
Usually, a crane is often used as a means for holding the cartridge above, but if you try to insert the cartridge into the building unit while it is suspended by the crane, the wire of the crane will come into contact with the building unit to be replaced. Will end up.

For this reason, when the cartridge is exchanged using the crane, the wires of the crane are connected to the cartridge with the cartridge half pulled out, or the wires of the crane are removed with the cartridge half inserted, and the parallel wires are removed at the same time. Work is inevitable.
However, in the above-mentioned simultaneous parallel work, the work becomes difficult and the possibility of work mistakes cannot be avoided due to the complicated procedure. Further, since the work is carried out with the building unit partially inserted, the cartridge becomes unstable, and there is a problem in workability and safety.

An object of the present invention is to provide a method and a device for replacing a building unit cartridge, which allows easy and reliable operation.

[0011]
