0 is configured similarly to the structure shown in FIG.

The framework of the living room unit 100 with stairs is
As shown in FIG. 5, the configuration of four lower beams 103, four columns 104, and four upper beams 105 is the same as the framework of the living room building unit 40 shown in FIG.
A rectangular parallelepiped outer frame is formed. A staircase 110 is attached to one end of the outer frame in the longitudinal direction. The underfloor beam 106 is erected over the entire frame constituted by the lower beam 103, and the ceiling beam 107 is erected in a region other than the area where the stairs 110 are provided in the frame constituted by the upper beam 105.

The upper end of each of two long and short columns 130 supporting the stairs 110 is fixed to a mounting surface 118 formed on the lower surface of the stairs 110 by bolts, and the lower end is formed between the lower beam 103 and the under-floor beam 106. Between, or under-the-beam 10
It is fixed with bolts to the receiving plate 108 attached between the six members. In addition, the upper floor may be joined to the upper beam of the building unit on the floor beam of the building unit without providing the support 130.

The building units 40, 50, and 95 and the building unit 100 with stairs are assembled in a factory in unit units and transported to a construction site. At the site, after the foundation is constructed, the room building unit 95 for one layer is arranged using a crane or the like, and the room building unit 40 for two layers is arranged thereon. The three-level living room building unit 50 and the staircase-equipped building unit 100 are stacked and arranged on the two-level living room building unit 40 using a crane or the like. A balcony 60 is provided on one side of the three-level unit.
Attach the eaves on the outer periphery of the upper beam of the three-level unit.
Cover with 5. With such an assembling process, it is not necessary to attach an external staircase on site for the staircase from the balcony 60 to the rooftop 115.

Next, the operation of the first embodiment will be described.

In the building unit 100 with stairs according to the first embodiment, it is possible to enter and exit the adjacent balcony 60 space and further enter and exit the building unit on the upper floor or the roof 115 from the space on the stairs 110. And can be configured as a top floor unit.

When the building unit is used as the top floor unit, a stair communicating from the balcony 60 space to the roof 115 can be formed.

The space under the stairs 110 is continuous with the space in the living room 120 and is separated from the external space, and the waterproof layer 11 is formed along the surface of the stairs 110.
6 is formed, there is no risk of rainwater entering the living room 120.

For this reason, the space under the stairs 110 is
It can be used as a space that is continuous with 0, so that space efficiency such as storage can be improved.

Further, the building unit 100 with stairs can be used to enter and exit the space of the adjacent balcony 60 and to access the stairs 11.
A unit building 90 having a top floor that allows access to the rooftop 115 and the like from the space above 0 is further configured.

The living room unit with stairs 100
Are stacked as a building unit on the top floor, and the stairs 110 are configured such that an upper floor 112 thereof can enter and exit a roof 115.

The space on the stairs in the building unit 100 with stairs is separated from the living room 120,
The space under the stairs 110 is continuous with the space in the living room 120, and the waterproof layer 11 extends along the surface of the stairs 110.
Since rainwater 6 is formed, the rainwater flows down the stairs 110 from the rooftop 115 and flows down toward the balcony 60.

Therefore, the space under the stairs can be used as a space continuous with the living room.

Also, the staircase 110 is a wall panel 110
Thus, since it is separated from the external space, the affinity with the side wall of the unit building 90 is good, and the appearance quality can be improved.
