[0020]

According to the invention of the present application having the above construction, the structural material for building is formed in a square shape in cross section, so that the C channel cross section conventionally used as a structural material in a steel house is used. The cross section has an excellent compression strength. Since the inside of the rectangular cross section is filled with an elastic body of a synthetic resin such as styrene foam, joining with a drilling tapping screw, a screw nail or the like is easy. In addition, in the vertical joining of the columns, since the shaft bolt is tightened by a long nut with a flange protruding outward, a tensile force can be borne, so that a tensile reinforcing metal such as a hole-down metal is unnecessary. It is excellent in terms of strength and the like. At the time of construction, only bolts are tied at the site, so no special jig is required, anyone can perform the work in a short time, and reduction in member cost can be expected.
