Next, the construction method of the unit type building 1 of this embodiment is demonstrated.
First, the first building units 31, 41, the second building units 32, 42, the third building units 33, 43 and the fourth building units 34, 44, the components of the roof 5, the blocking wall panels 35, 45, the blocking The ceiling panel 46, the reinforcing beams 71 and 72 and the outer peripheral reinforcing beams 73 and 74 are manufactured in a factory, and these are transported to the construction site.

Thereafter, the first building unit 31, the second building unit 32, the third building unit 33, and the fourth building unit 34 for the lower floor are arranged on the foundation 2 that has been previously constructed at the construction site. At this time, the second building unit 32 and the third building unit 33 are arranged so that the short sides thereof face each other in the long side direction of the first building unit 31, and the second building unit 32 and the third building unit 33 are arranged. Are spaced apart from each other by a predetermined distance L.
A blocking wall panel 35 is disposed on the outer surface side between the second building unit 32 and the third building unit 33.

Further, the reinforcing beam 71 is arranged along the long side ceiling beam 11 </ b> A of the first building unit 31, and the reinforcing plates 711 and 712 are engaged with the building units 31 to 33. Then, the outer peripheral reinforcing beam 73 is engaged with the second building unit 32 and the third building unit 33.
Thereafter, the first building unit 41 for the upper floor is disposed on the first building unit 31, the second building unit 42 for the upper floor is disposed on the second building unit 32, and the third building unit for the upper floor is disposed. The building unit 43 is arranged on the third building unit 33, and the fourth building unit 44 for the upper floor is arranged on the fourth building unit 34. Therefore, also in the upper floor portion, the second building unit 42 and the third building unit 43 are arranged so that the short sides thereof are opposed to each other in the long side direction of the first building unit 41. The three building units 43 are spaced apart from each other by a predetermined distance L.
As a result, the reinforcing beam 71 is sandwiched between the upper and lower building units 31 to 33 and 41 to 43, and these are connected and fixed to each other by the bolt 14B.

In this state, the reinforcing beam 72 is sandwiched between the building units 41 to 43 and the cabin back panel 6, and these are connected and fixed to each other. Then, the roof 5 is constructed on the back panel 6.

According to the present embodiment as described above, the following operational effects can be achieved.
(1) Planar rectangular second building units 32, 42 and third building units 33, 43 are arranged so that the short sides thereof are opposed to the long sides of the first rectangular rectangular building units 31, 41, respectively. The second building units 32, 42 and the third building units 33, 43 were placed apart. Therefore, the first building units 31 and 41 are placed vertically, the second building units 32 and 42 and the third building units 33 and 43 are placed horizontally, and the second building units 32 and 42 and the third building units 33 and 43 are placed sideways. Can be effectively used on the site by separating them so that the long sides of the first building units 31 and 41 are full.

(2) The long side direction of the first building unit 31, 41 is between the long side direction of the first building unit 31, 41 and the short side direction of the second building unit 32, 42 and the third building unit 33, 43. Since the reinforcing beams 71 and 72 are provided along the first building unit 32, even if the second building units 32 and 42 and the third building units 33 and 43 are separated from each other, the first building unit is interposed via the reinforcing beams 71 and 72. Since the 31, 41, the second building units 32, 42 and the third building units 33, 43 are integrated, the reinforcing effect of the building itself can be increased.

(3) Since the second building unit 32, 42 and the third building unit 33, 43 are closed by the closing wall panels 35, 45, the second building unit 32, adjacent by the closing wall panels 35, 45, A continuous large room R can be formed between 42 and the third building units 33 and 43.

(4) Since the second building unit 32 and the third building unit 33 for the lower floor are provided with the column-deficient corner portion A at a portion close to each other, the living room R can be a large space without a column.

(5) Since the reinforcing beams 73 and 74 for the outer periphery are disposed between the second building units 32 and 42 and the third building units 33 and 43, they are also used as connection plates for connecting the building units to each other. Can do. Therefore, there is no need to provide a separate connection plate, and as a result, the members can be shared, and the members can be saved.

The present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
For example, in the above-described embodiment, the reinforcing beams 71 and 72 are configured to include the main body 710 made of a plate-like member having a predetermined thickness. However, the shape of the main body 710 is not limited to this, and for example, has a rectangular cross section. A square pipe may be used. In such an embodiment, by appropriately increasing the thickness of the square pipe, the living room area can be increased by the difference from the plate member.

In the above embodiment, the first building units 31, 41, the second building units 32, 42, and the third building units 33, 43 are arranged on the lower floor portion and the upper floor portion of the building, respectively. The first building unit 31, the second building unit 32, and the third building unit 33 may be arranged only on the floor portion, and the second building unit 32 and the third building unit 33 may be separated from each other.
In the present invention, it is not always necessary to arrange the fourth building units 34 and 44.
