However, the steel itself is excellent in heat conduction, rusts due to moisture, and has good sound propagation, and there is a disadvantage that vibration on the second floor propagates to the entire building including the first floor. . Further, in heat conduction, there is a drawback that dew condensation occurs due to an air cycle or the like, causing rust or corrosion of nearby materials.

[0004]

SUMMARY OF THE INVENTION The present invention, in order to eliminate such a drawback, requires that at least one of an interior material and an exterior material that is in contact with a steel frame is in direct contact with the frame. In order to avoid this, a heat-insulating attachment body is fixed to the body so as to protrude from the body, and the back surface of the interior material and exterior material including the protrusion of the attachment body is insulated and air-tightly covered with a plastic foam, and condensation is formed. The present invention proposes a steel house wall structure capable of suppressing generation of heat, improving durability, reducing sound and heat propagation and conduction, and coping with resource depletion.
