Bin sidewall panel concept

A storage bin comprising:

• a corrugated outer sidewall including first and second corrugated sheets having 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, a horizontal end of the first corrugated sheet defining a first aperture and a horizontal end of the second corrugated sheet defining a second aperture;
• a rigid metallic generally flat inner sidewall including first and second generally flat sheets abutting the radially inner ridges, a horizontal end of the first flat sheet defining a third aperture and a horizontal end of the second flat sheet defining a fourth aperture, the horizontal ends of the first corrugated sheet and the first flat sheet overlapping the horizontal ends of the second corrugated sheet and the second flat sheet, the first corrugated sheet and the first flat sheet extending in a first horizontal direction and the second corrugated sheet and the second flat sheet extending in a second horizontal direction opposite the first horizontal direction, the second corrugated sheet being located radially between the first corrugated sheet and the first flat sheet, and the first flat sheet being located radially between the second corrugated sheet and the second flat sheet;
• and
• a first fastener extending in order, first through the first aperture, then through the second aperture, then through the third aperture, and then through the fourth aperture and coupling the inner and outer sidewalls to one another and joining both the first and second flat sheets and the first and second corrugated sheets along a common vertical overlapping seam for both the corrugated outer sidewall and the flat inner sidewall.

A storage bin comprising:

• a corrugated outer sidewall forming an outer hoop supporting a hoop tension 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;
• a rigid metallic generally flat inner sidewall forming an inner hoop supporting the hoop tension and defining a second aperture;
• a first fastener extending through the first and second apertures and coupling the inner and outer sidewalls to one another;
• a column member fixed to the inner and outer sidewalls and supporting a vertical load of the storage bin;
• and
• a roof assembly supported by the column members, the overall radial material thickness of the combined inner and outer sidewalls being greater at a region near a base of the storage bin than a region near the roof assembly;
• wherein the inner sidewall includes an integrally formed protrusion provided as embossment of the inner sidewall and extending radially outward from an outer surface contacting against one of the radially inner ridges and creating a vertical communication path between radially inner ridges of adjacent grooved portions and the outer surface of the inner sidewall;
• 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.
