Abstract: A roof system for a grain storage structure. The roof system includes a plurality of enclosures defined between adjacent roof panel surfaces. Each enclosure includes opposed exterior and interior wall segments oriented at an angle relative to the panel surfaces.

Abstract: A grain bin floor support system having a plurality of interconnected support members. The support members are constructed from a monolithic sheet of structural metal stamped and formed having upper and lower horizontal rails spanning across and integrally connected by a plurality of transverse support columns. The rails include a longitudinally extending center segment and a stabilizing portion adjacent each end thereof. The stabilizing portions are configured to be folded out in opposite directions forming a non-planar self-supporting structure.

Abstract: A granular material storage container and associated method. The storage container includes a foundation, a peripheral wall supported on the foundation, a plurality of vertical stiffeners attached to the peripheral wall, and a horizontal connector connecting the peripheral wall to the foundation. The horizontal connector extends between at least a pair of vertical stiffeners and operates for load transfer from the peripheral wall to the foundation during single pass sweeping.

Abstract: There is disclosed a guard for the discharge opening of a grain bin which assures free flow of grain therethrough by precluding blockage of the opening by compacted grain. The guard includes a plurality of blades which are adapted to be disposed over the opening. The blades extend substantially perpendicularly to the opening and include grain engaging cutting edges for cutting and breaking-up compacted grain over the discharge opening to assure free flow of grain therethrough. The guard is also readily removable from its operative position over the discharge opening to permit complete emptying of the bin by a sweep auger.
