<P>PROBLEM TO BE SOLVED: To solve the unsettled problems of a conventional (present) wooden house structure in the connecting points of entire columns: that a ceiling falls down in various districts only by a weak side of earthquake of a seismic intensity of 5 or less which usually causes only small articles to drop from a shelf; that investigation over the various districts reveals that an L-shaped fitting of as thick as 2 mm or so is used for the fixture at the connecting points and the fitting is deformed into one flat plate when the lateral ends of the fitting are held by the hand of an 81 years old healthy man; and that a larger fitting to be provided requires a larger bolt setting hole and actually eight larger bolt holes require to be drilled at the ends of each column to fairly reduce the strength of the columns, with dangerous situation in terms of resistance against earthquake. Ž<P>SOLUTION: One type of the geometrically formed single geometric frame (3A), wherein triangle-shaped frames are connected in an overlapping way, is only provided to the ceiling and on the floor of a newly-built house fundamental structure (4) or of an existing house structure, causing the four column faces and two faces of ceiling and floor in total of six faces in elevation to be integrated to the vertical structure face.
