BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit type building constructed by combining a plurality of building units.

[0002]

BACKGROUND ART A unit-type building such as a house is constructed by bringing a plurality of building units, roof panels, etc., produced in advance in a factory to a construction site, and combining each unit there. When such a unit-type building is used as, for example, a two-story apartment house, an outer staircase and an outer corridor are often provided outside the building and as an entrance on the second floor over each residence. However, the outer staircase and the outer corridor may not be provided outside the building depending on conditions such as the size and shape of the site where the building is built.
In such a case, part of each building unit should be dented, combined so that they form a planar U-shape, and the part surrounded by the U-shape part shall be an open space. An outer corridor will be installed.

Ideally, a unit-type building should be completed by simply combining the units produced in the factory in advance at the construction site. Therefore, it is desirable to unitize the outer stairs and outer corridors as much as possible.
By the way, the effective widths of the outer stairs and the outer corridor are determined respectively, and generally, the total effective width of the outer stairs and the outer corridor is wider than the width of the building unit in the short side direction. Therefore, even if the outer stairs and the outer corridor are unitized in advance, there is a problem that they cannot be transported because they are subject to transportation restrictions. Therefore, conventionally, in a factory, for example, a floor material for a corridor is attached to a frame body in which grooved steel is combined to produce an outer corridor having a substantially L-shaped plane, and the corridor is formed at each corner of the corridor at a construction site. Assemble the pillars to support the height of the second floor, and then attach stairs, etc., and place it in the open space of the unit building.

[0004]

However, in the unit type building as described above, the outer corridor and the pillars have to be assembled at the site, and there is a problem that the site work increases and becomes complicated.

It is an object of the present invention to provide a unit-type building having an outer staircase and an outer corridor which can be transported without touching transportation restrictions, requires less on-site work, and can be easily assembled. It is in.

[0006]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a second building unit is arranged between a first building unit arranged in parallel to each other in a horizontal plane with a predetermined space therebetween, and a second building unit including the space is arranged in a direction in which the building units are arranged. In a unit type building that is arranged in a direction orthogonal to the above, and the space surrounded by these building units is an open space, a substantially rectangular third unit is provided in the open space as the second building unit. It is a unit-type building with a gap in between.

In this unit type building, the substantially quadrangular third unit is an outer staircase unit produced by previously assembling the outer staircase in the structure in the factory, and the outer staircase unit and the second staircase unit An outer corridor panel that closes the gap may be provided in the gap with the building unit. Further, in the unit type building, the substantially quadrangular third unit may be a building unit.

[0008]

According to the present invention as described above, the first building units are arranged in parallel with each other with a predetermined space apart in the horizontal plane,
The second building unit is arranged between the building units so as to be displaced in a direction orthogonal to the arrangement direction of the building unit including the space. Then, the space surrounded by these building units is made into an open space, and the substantially square third unit is the second space in this open space.
It is installed with a gap from the building unit. Since the third unit is separate from the second building unit, it can be transported without touching the transportation restrictions.

In this unit type building, the third unit is an outer staircase unit produced by previously assembling the outer staircase in the structure in the factory, and the outer staircase unit and the second building unit are combined. If there is an outer corridor panel that closes this gap, the outer staircase unit will be
Since it is manufactured separately from the building unit, it can be transported without touching the transportation restrictions, and since the outside stairs have been assembled in the factory in advance and the outside corridor panel is also installed, they will be installed on site. It is easy to assemble, requires little on-site work, and can be easily assembled.

In the unit type building, the third
If the unit is a building unit, the third unit is separate from the second building unit and can be transported without touching the transportation restrictions.
