[0001]

The present invention relates to a building unit. More specifically, the present invention relates to a so-called pentagonal building unit in which a part of a roof panel is formed on an inclined roof portion.

[0002]

2. Description of the Related Art As a building unit such as a house used in a unit construction method, a rectangular floor panel, four columns erected at four corners of the floor panel, and bridged between upper ends of the columns, and 2. Description of the Related Art An ordinary box-shaped building unit formed in a substantially rectangular parallelepiped shape from a rectangular roof panel as viewed from a plane is known. In addition, a so-called pentagonal building unit in which a part of a roof panel is formed on an inclined roof portion so as to be able to cope with a northern oblique line restriction in the Building Law, etc., is also known.

For example, as shown in FIG. 7, two short columns 3A and 3B are provided on one end (short side) of a floor panel 2 framed in a rectangular shape, and the other end (on the other end). (Long side), two long columns 4A, 4B are erected respectively, and these columns 3A,
A roof panel 5 having a flat roof portion 5A and a sloping roof portion 5B is stretched between upper end portions of 3B, 4A, and 4B.
That is, a pentagonal building unit 1B is known in which a flat roof 5A is laid so as to be positioned on the long columns 4A and 4B side and an inclined roof 5B is positioned on the short columns 3A and 3B side. .

As shown in FIG. 8, two short columns 3A and 3B are provided on one side (long side) of a floor panel 2 framed in a rectangular shape, and the other side (side). Two long columns 4A, 4B are respectively erected on the long side) and these columns 3A, 3B
B, 4A, and 4B, a roof panel 5 having a flat roof portion 5A and a sloping roof portion 5B is stretched between upper end portions, that is, the flat roof portion 5A is inclined toward the long columns 4A, 4B and inclined. A pentagonal building unit 1C is known in which a roof 5B is bridged so as to be positioned on the short columns 3A, 3B side.

[0005]

However, in the conventional pentagonal building units 1B and 1C, if the corners of the long side and the short side have to be arranged toward the north side due to the site, etc., the north side There may be cases where it is not possible to cope with oblique line restrictions. For example, as shown in FIG. 9 and FIG.
When corners of the long sides and the short sides of B and 1C must be arranged toward the north side N, there remains a problem that the long side or the short side is subject to the north side oblique line restriction.

The above two types of building units 1B, 1
Even if you try to meet the northern diagonal limit by combining C,
Since one of the building units 1B and 1C will be located in the northern corner, these building units 1
In B and 1C, the arrangement direction depends on the site and the like.
Alternatively, when the state is restricted to the state shown in FIG. 10, it is practically difficult to prevent all the parts from being restricted by the northern diagonal line.

[0007] It is an object of the present invention to solve such a conventional problem and to provide a building unit capable of coping with northern oblique line restriction without being restricted by arrangement.

[0008]

Therefore, a building unit according to the present invention has a rectangular plate- like floor panel, four columns erected at four corners of the floor panel, and bridges between upper ends of these columns. And including a rectangular plate- shaped roof panel when viewed from a plane,
In the building unit formed in a substantially rectangular parallelepiped shape, three of the four pillars are formed to be shorter than the remaining pillars and have the same size as each other, and the roof connecting the short pillars is formed. Two sides adjacent to each other of the panel are characterized by an inclined roof portion, and the other portions are characterized by a flat roof portion.

[0009]

When a unit building is constructed by assembling a plurality of building units, a corner sandwiched between two adjacent sloped roofs is arranged at the northern corner toward the north. Then, since both the long side and the short side are not restricted by the northern diagonal line, it is possible to cope with the restriction on the northern diagonal line without being restricted by the arrangement.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. In the description of these drawings, the same components as those in FIGS. 7 to 10 described above are denoted by the same reference numerals, and description thereof will be omitted or simplified.

FIG. 5 shows a plan view of the unit building.
The unit building includes the ordinary building unit 1A, the pentagonal building unit 1B, and the building unit 1C.
And the building unit 1D of the present embodiment are assembled together and built. The arrangement of these building units is
The building unit 1A is arranged diagonally at the southern corner and the building unit 1D of the present embodiment is arranged diagonally at the northern corner, and the building unit 1B and the building unit 1C are arranged between them.

As shown in FIGS. 1 to 3, the building unit 1D according to the present embodiment is erected at four corners of a floor panel 2 having a rectangular plate shape.
Of the four pillars, three pillars 3A, 3B, and 3C are formed shorter than the remaining pillars 4A and have the same size as each other. In addition, two rectangular sides adjacent to each other of the rectangular plate-shaped roof panel 5 connecting the short columns 3A to 3C, that is, the inclined roof part 5B having the same gradient on the short side and the long side. ,
5C, and other portions are formed on the flat roof portion 5A.

More specifically, as shown in FIG.
Frame 6 with the upper end of the corner as a corner (rectangular frame shorter than the long side and short side of building unit 1D)
And the remaining three corners of the frame body 6 and the short columns 3A, 3
Three inclined beams 7 for connecting the upper ends of B and 3C in an inclined manner.
A, 7B, 7C and roof frames are formed from the roofing material 8A on the roof frame, 8B, 8C are mounted flat roof 5 A and slanted roof section 5B, 5C are formed. 9B and 9C are three short columns 3A and 3
It is a beam connecting the upper ends of B and 3C.

With such a configuration, when building the unit building shown in FIG. 5, a normal building unit 1 is located on the south side.
A, the building unit 1D is arranged diagonally on the north side, and the building unit 1B and the building unit 1C are arranged between them. At this time, the building units 1D are arranged so that the corners of two adjacent inclined roof portions 5B and 5C face the north side N. Further, the building unit 1B is arranged so that the sloping roof 5B faces the outside on the west side, and the building unit 1C is arranged such that the sloping roof 5C faces the outside on the east side.

In this case, all the short sides and long sides of the building units 1B, 1C, 1D facing the north are formed on the inclined roof portions 5B, 5C, so that all the parts are subject to the north side oblique line restriction. Nothing.

Therefore, according to this embodiment, the roof panel 5
Two sides adjacent to each other are inclined roof portions 5B,
Since it is formed in 5C, even when the building unit 1D has to be arranged so that the corners of the long side and the short side are directed to the north side, both the long side and the short side are not subject to the north side oblique line restriction, It is possible to cope with the northern diagonal line restriction without being restricted by the arrangement.

Incidentally, the frame structure of the roof panel 5 is not limited to the structure of the above-described embodiment.
The structure of FIG. 6 may be used. This is because beams 9B and 9B are located at corners of the rectangular frame 6 that are diagonally opposite to the long pillar 4A.
The point that two inclined beams 7B-1 and 7B-2 are provided in parallel to the inclined beams 7A and 7C toward C is different from the structure of FIG. In this way, the number of beams gathering at the upper end of the short column 3B is reduced as compared with the structure of FIG. 4, that is, the number of beams can be reduced from three to two, so that processing of this part can be facilitated. There are advantages.

[0018]

As described above, according to the building unit of the present invention, the two adjacent sides of the roof panel are formed in the inclined roof portion, so that two adjacent inclined shapes are formed in the northern corner. Even if the corners of the roof part are arranged toward the north side, both the long side and the short side are not restricted by the north diagonal line, so that it is possible to cope with the restriction of the north diagonal line without being restricted by the arrangement.
