Panel structure of steel house and panel constructing method

A panel structure of steel house built by constructing multi-story structural frameworks by forming wall panels by fastening face members to rectangular frames of light-gage channels of sheet steels, constructing walls of each story by disposing said wall panels along the four sides of a rectangle, and assembling said wall panels and a floor panel comprising a wall plate mounted on floor joists, the panel structure characterized by that;

• the upper edges of the wall panels of the lower story on two opposite sides are held lower than the upper edges of the wall panels of the lower story on other two opposite sides, and both edges of said floor panel are mounted on the upper edges of the lower wall panels of the lower story on two opposite sides,
• the upper surface of said floor panel is held by the lower edges of wall panels of the upper story on two opposite sides, and both sides of said floor panel are connected to the inner upper end of the higher wall panels of the lower story on the other two opposite sides, and
• the end edges of the higher wall panels of the lower story on two opposite sides and the end edges of the wall panels of the upper story on two opposite sides are butt-joined.
