Abstract: A sloped bin grain elevator is formed of preformed structural components and has the bins therein sloped at or near the angle of repose at the stored material to create a non-confined grain flow pattern. The elevator building structure includes an inclined base, a sloped roof and side walls as well as end walls and a plurality of interior partitioning walls. Each bin in the elevator has a series of staggered intermediate levels so as to divide the depth of the bin into various layers. The staggered intermediate levels of the bins are formed by a series of precast slabs, the width of each slab being slightly less than half the width of the bin, the slabs being positioned end to end in a staggered pattern whereby the entire length of each bin forms one intermediate continuous layer of slabs.
