PURPOSE:To secure structural strength of a composite corrugated plate even if it is placed in the horizontal or vertical direction, by mutually crossing waveforms having a rectangular section, which exist extendedly in the back and forth directions and the left and right directions, and connecting both waveforms to each other by a vertical cylinder formed in its intersection point. CONSTITUTION:A fundamental waveform whose section is like a rectangular wave, existing extendedly in the back and forth directions, which has been constituted of a vertical side wall 6a of the front side, a bottom wall 2, a vertical side wall 6b of the rear side, a top wall 4, the vertical side wall 6a of the front side..., and a fundamental waveform whose section is like a rectangular wave, existing extendedly in the left and right directions, which has been constituted of a vertical side wall 7a of the left side, a bottom wall 1, a vertical side wall 7b of the right side, a top wall 4, the vertical side wall 7a of the left side... are crossed to each other at a right angle, and the waveforms in two directions are connected at each intersection point by a circumferential side wall 5 and a horizontal wall 8 of a vertical cylinder 3. |
