PROBLEM TO BE SOLVED: To provide a common space structure formed of poles and frames and constructed to maintain a rectangular shape in plan view by firmly connecting a plurality of frames and poles to each other even if an external force is applied from the outside to the poles. SOLUTION: The common space structure 1 is formed in a rectangular shape in plan view by connecting the poles 3a, 3b, 3c, and 3d to frames 41. The poles 3a, 3b, 3c, and 3d opposed diagonally to the the poles 3a, 3b, 3c, and 3d are connected to each other through a wire material 40 so that a tension in a direction for pulling these poles to each other is added. Since the poles 3a, 3b, 3c, and 3d are pulled to each other with the tension of the wire material 40, the frames 41 formed in the rectangular shape in plan view is kept in a horizontal state to always keep the poles 3a, 3b, 3c, and 3d connected to the frames 41 in a vertical state, the poles can be firmly maintained and reinforced. Accordingly, the common space structure 1 capable of withstanding an external force from the outside can be constructed. COPYRIGHT: (C)2005,JPO&NCIPI
