Abstract:
1. A storage bin comprising: a corrugated outer sidewall supporting a portion of a hoop tension load provided by a material within the storage bin and including a series of horizontally extending corrugations forming alternating grooved portions defining alternating circumferentially extending radially inner and outer ridges vertically spaced from one another along a vertical extent of the outer sidewall, the corrugated outer sidewall defining a first aperture, and the corrugated outer sidewall including a plurality of corrugated sheets with vertically adjacent corrugated sheets of the corrugated outer wall forming a horizontal overlapping joint seam; a rigid metallic generally flat inner sidewall supporting a portion of the hoop tension load, abutting the radially inner ridges and defining a second aperture, the flat inner sidewall including a plurality of flat sheets with vertically adjacent flat sheets of the flat inner sidewall forming a horizontal end-against-end butt joint seam and horizontally adjacent flat sheets of the flat inner sidewall forming a vertical overlapping joint seam; and a first fastener extending through the first aperture of the corrugated outer side wall and the second aperture of the flat inner side wall and coupling the inner and outer sidewalls to one another; wherein the corrugated outer sidewall includes first and second corrugated sheets and the inner sidewall includes first and second flat sheets, the first corrugated sheet extending in a first horizontal direction and including a first horizontal end portion defining the first aperture, the first flat sheet located radially between the second corrugated sheet and the second flat sheet, extending in the first horizontal direction, and including a second horizontal end portion defining the second aperture, the second corrugated sheet located radially between the first corrugated sheet and the first flat sheet, extending in a second horizontal direction opposite the first horizontal direction, and including a third horizontal end portion defining a third aperture, and the second flat sheet extending in the second horizontal direction and including a fourth horizontal end portion defining a fourth aperture, the fastener passing through the first, second, third, and fourth apertures and coupling the outer sidewall to the inner sidewall.
