Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of expanding a unit house, and can be used when a new floor is added to the unit house.

[0002]

BACKGROUND ART Conventionally, there is a unit house that can be built in a short period by assembling a housing unit such as a living room unit or a roof unit manufactured at a factory at a construction site.

As a procedure for adding a new floor to such a unit house, as shown in FIG. 8, after removing the roof unit 50 from the unit house 51, a new unit is placed on the living room portion 52 on the uppermost floor. A general procedure is to construct an extension part, mount the roof unit 50 removed on the extension part, and reassemble the roof part 53.

[0004]

By the way, in the unit housing as described above, the roof units 50 are not directly joined to each other, but are joined to the plurality of living room units 55 connected by the sheer plate 54. It is integrated by doing. Therefore, in the conventional extension method as described above, when removing the roof portion 53 from the unit housing 51,
Each of the roof units 50 is separated and the roof portion 53 is disassembled.

Therefore, it is necessary to remove and install the roof unit 50 for each individual roof unit 50, which requires a lot of time and effort to make the extension work complicated. Further, since each of the roof units 50 is in a separated state, the waterproof seal portion applied to the joint 56 between the roof units 50 is destroyed, and it is necessary to perform joint treatment again after reassembling the roof portion 53, Since this joint processing work is troublesome, there is a problem in that the extension work is complicated from this point as well. An object of the present invention is to provide a method of adding a unit house that facilitates the addition work.

[0006]

A method for expanding a unit house according to the present invention is a method for expanding a unit house constructed by connecting house units and arranging roof units on the uppermost floor. , The top floor is separated from its lower part, and this top floor is lifted up integrally with the roof part,
After constructing a new extension part on the lower part, the top floor and the roof part are integrally placed and fixed on the extension part.

If the unit house to be expanded is a two-story building, the original second floor is the top floor and the original first floor is the lower part. If the unit house is a one-story house, the original first floor will be the top floor and the foundation will be the lower part.

[0008]

In the present invention as described above, the living room portion and the roof portion on the uppermost floor are integrally removed and reinstalled, so that the roof portion is not disassembled. For this reason, it is not necessary to perform the work for each roof unit, and the joint treatment work is unnecessary, thereby achieving the above object.

[0009]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the entire two-story unit house 1 according to this embodiment. In the figure, a unit house 1 is a box-shaped living room unit 10,2 manufactured at a factory.
It was constructed by assembling multiple 0 etc. The living room unit 10 is installed on the first floor portion of the house 1 and forms a lower living room portion 11 on the first floor.
20 is installed on the second floor of the house 1 and forms a living room portion 21 on the second floor, which is the top floor. A plurality of roof units 30 are placed on the living room unit 20 to form a roof portion 31. The eaves unit at the eaves part of the roof part 31
32 are installed.

Here, a sheer plate (not shown) for connecting the living room units 20 to each other is interposed between the living room unit 20 and the roof unit 30 as in the conventional unit housing. The roof portion 31 is integrated by joining the roof units 30 to the living room unit 20 with the shear plate interposed therebetween. Room 21 and room 11
The boundary part between and is the separation part A at the time of extension.

2 to 5 show a unit house 1 of this embodiment.
The example shows the construction of a three-story building. First, the connection between the living room 11 and the living room 21 is released, and the separated part A
The living room part 11 is separated along the line, and as shown in FIG.
The living room part 21 is lifted together with the roof part 31 and moved to a position where it does not hinder the extension work.

Next, as shown in FIG. 3, the living room portion
A plurality of new living room units 40 are installed on 11 to construct an additional living room portion 41 which is an additional building portion.

Subsequently, as shown in FIG. 4, the living room portion 21 and the roof portion 31 separated from each other on the extension living room portion 41 are integrally placed and fixed.

Next, work such as joining the living room unit 20 of the living room portion 21 and the living room unit 40 of the extended living room portion 41 to each other is performed, and the unit housing 1 is made into a three-story building as shown in FIG. Complete the extension work.

According to this embodiment as described above, the living room portion
21 and the roof portion 31 are integrally removed and reinstalled so that the roof portion 31 is not dismantled even if the roof portion 31 is removed from the unit housing 1. Therefore, work for each roof unit 30 individually. Is eliminated, and the extension work can be facilitated.

Further, since the roof portion 31 is not dismantled, the waterproof seals and the like applied to the joints of the roof unit 30 at the time of new construction are not destroyed, and it becomes unnecessary to perform joint treatment work again. Work can be done easily.

Further, in many cases, stairs are not generally installed on the uppermost floor of the house, and the conventional extension method requires modification work to install a new staircase on the original uppermost floor. On the other hand, as shown in FIG. 6 and FIG. 7, the uppermost floor of the living room portion 21 is maintained regardless of before and after the extension, so that the living room portion 21 can be used as it is and the extension living room portion can be used. Since it is possible to easily deal with stairs 42 provided in advance to 41, the addition work can be facilitated also in this respect.

The present invention is not limited to the above-mentioned embodiment, but includes the following modifications. That is, the unit housing before the extension is not limited to the two-story building, but may be, for example, a three-story building or a one-story building.
In the case of a one-story house, the first floor part may be the living room part, the foundation may be the lower part, the first floor part may be separated from the foundation, and an extension part may be built on the foundation.

Further, the outer shape of the unit house is not limited to the one having a quadrangular plane shape, and for example, the plane shape has an L shape,
It may be concave or convex. Further, the form of the roof portion is not limited to the gable roof shape, and may be, for example, a flat roof shape or a dormitory roof shape, or a rooftop or a penthouse capable of walking. In short, the exterior shape of the unit housing is not limited as long as it is formed by assembling housing units such as living room units and roof units.

[0020]

As described above, according to the method for expanding a unit house of the present invention, the expanding work can be facilitated.
