<p><P>PROBLEM TO BE SOLVED: To enhance a restraint effect against deformation between bent portions of diagonal columns, and to enhance horizontal rigidity in the minimum unit of a frame, in the diagonal frame constituted of beams, and the plurality of diagonal columns between the beams under an inclined state with respect to a vertical direction. <P>SOLUTION: The diagonal frame 1 is constituted of the outer circumferential beam 2 in each layer, and the plurality of diagonal columns 3 laid with a space each other along a longitudinal direction of the outer circumferential beam 2, between the upper and lower outer circumferential beams 2, 2, under the inclined state with respect to the vertical direction, the diagonal columns 3 are laid continuously in a zig-zagged state between the plurality of layers, and the outer circumferential beam 2 is connected to at least the zig-zagged bent portion of each diagonal column 3. The diagonal column 3 is inclined axisymmetrically as to an axis of any of the outer circumferential beams 2. The outer circumferential beam 2 is added to the bent portion of the diagonal column 3, and is laid in an intermediate position between the bent portions. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
