Abstract
This invention relates to an assembly comprising a first corrugated sheet and a second generally planar sheet. The corrugations form alternating apices on opposite sides and equidistant from a central major plane in the first sheet, where the apices are connected by angled walls. The second sheet has a central major plane which is generally parallel to the central major plane of the first sheet. The second sheet has complementary regions disposed in overlapping adjacent complementary relation to, and abutting the apices of, the first sheet. The second sheet has undulating regions disposed between the complementary regions, where the undulating regions alternate above and below the central major plane of the second sheet. The undulating regions alternating above the central major plane of the second sheet have a peak wavefront and the undulating regions alternating below the central major plane of the second sheet have a valley wavefront, whereby the wavefronts of the undulating regions are angled with respect to longitudinal axes of the complementary regions to an extent necessary to interlock adjacent first and second sheets.
