(5) Since the asphalt sheet 50 has a sheet shape, the asphalt sheet 50 can be easily attached to the inner surface of the side wall portion 22.
And since the ant-proof heat insulating member 52 is a hard foaming resin panel impregnated with an ant-proofing agent, the provision of the hard foaming resin-like panel can surely provide the ant-proofing property and the heat insulating property by easy construction.

(6) Since the storage space 5 surrounded by the floor panel 51B, the inner wall panel 53C, and the ceiling panel 54 has a ceiling height of about 1.4 m, the space that can be used as a basement is the lowest. The limit can be secured. Further, when the deep foundation 2 is provided, the ceiling height is about 1.4 m, so that the amount of excavation can be reduced compared to the case where a residential space is provided, and the construction cost can be suppressed. .

The filler 60 may be the same ant-proof heat insulating member as the ant-proof heat insulating member 52. That is, the building unit 4 may be placed on the side wall portion in a state where the upper end portion of the ant protection heat insulating member 52 protrudes upward by a predetermined dimension without filling the filler 60. That is, the ant-proof heat insulating member 52 is compressed in the vertical direction, and continues directly to the bottom surface of the building unit 4. In this case, sacrificial prevention is improved by the dense pressure effect.
And although the structure which provides the water stop 23A in the center part of the joint 23 was shown, application | coating waterproofing may be given instead of the water stop seal 23A. Moreover, you may give application | coating waterproofing with the water stop seal | sticker 23A.
Furthermore, although the structure in which the joint 23 is provided between the upper surface of the bottom plate portion 21 and the lower end edge of the side wall portion 22 is shown, for example, the bottom plate portion 21 and the side wall portion 22 are integrated into the concrete without providing the joint. You can hit it. In this case, since the joint is not provided, the water stoppage is further improved.
And although the ceiling height between the ceiling panel 54 and the floor panel 51B showed the structure currently set to about 1.4 m, it is not restricted to this, Space height is provided larger than 1.4 m. It may be done. In this case, if the space height is 1.4 m or more, it can be used as a living part.
Moreover, although the thickness dimension of the baseplate part 21 showed the structure which is 20 cm or more, it is not restricted to this, For example, less than 20 cm may be sufficient. In this case, an anti-rust member may be provided on the bottom plate portion 21 as appropriate.
