In the building 10 of the present embodiment, the second heat insulating material 64 for the room wall surface insulates the outer wall surface side of the second living room 20, and the first storage room wall surface side heat insulating material 90 is provided on the wall surface side of the first storage room 22. Insulate.
Here, for example, the building 10 is shaken by an earthquake or the like, and the second living room 20 and the first storage room 22 are moved relative to each other in the horizontal direction. When at least one of the side heat insulating materials 90 deviates from the initial position at the time of construction, and the interval between the second living room wall surface insulating material 64 and the first storage room wall surface side heat insulating material 90 is partially or entirely expanded (or narrowed) Can be considered.

  However, in the building 10 of the present embodiment, the connecting heat insulating material 92 compressed between the second heat insulating material 64 for the wall surface of the living room and the heat insulating material 90 on the wall surface side of the first storage room is disposed. Even if a portion where the space between the second insulating wall surface heat insulating material 64 and the first storage wall surface side heat insulating material 90 is widened, the connecting heat insulating material 92 expands and extends at the portion, and the second living room wall surface The heat insulating material 64 and the first storage room wall surface side heat insulating material 90 are kept in contact with each other without opening a gap, and on the outer wall side, the heat insulating performance continues from the second living room 20 to the first storage room 22, The heat insulation performance of each of the second living room 20 and the first storage room 22 does not deteriorate, and high heat insulation performance can be ensured in both the second living room 20 and the first storage room 22.

  In the building 10 of this embodiment, since the second living room 20 and the first storage room 22 are provided independently, when the building 10 shakes during an earthquake or the like, each of them vibrates separately (behavior). Although there is a case where it shows, even if such a case arises, the heat insulation performance of each of the 2nd living room 20 and the 1st storage room 22 does not fall. In addition, since the 2nd living room 20 and the 1st storage room 22 are independent, each structural calculation can be performed separately and the 2nd living room 20 and the 1st storage room 22 are connected with a structure. The structure calculation becomes easier.

  Moreover, in the building 10 of this embodiment, since the 2nd living room 20 and the 1st storage room 22 are supported by the common foundation 34 and the foundation 36, relative of the 2nd living room 20 and the 1st storage room 22 is sufficient. Movement, that is, deviation can be reduced.
