に建築できる効果がある。[Effects] In the building and the building method according to the present invention, the core that receives all the horizontal pulling force of the building is formed in the center, and thereby the wall surface is supported through the wooden beam member. Since it has a structure, no stud is structurally required between the core and the wall surface, and therefore, the degree of freedom of layout is extremely high. Moreover, since this structure enables the weight of the entire building to be reduced, it has high earthquake resistance.
Furthermore, since the metal skeleton does not reach the wall surface unlike the conventional prefabricated building, the heat insulating property inside the building is extremely high. Moreover, since the roof purlin can be supported by the ramen structure core through the cane, the number of the cane is small, and therefore, the attic also has the effect of forming a wide space with high utilization. .. In particular, the construction method of the present application requires a very short construction period and can greatly reduce the participation rate of skilled workers, so a building with excellent heat insulation, airtightness, sound insulation, and high durability, There is an effect that it can be built cheaply in a short period of time.
