8' Autoflow FOUNDATION REQUIREMENTS ALL FOUNDATION SPECIFICATIONS SHALL BE CONSTRUED AS RECOMMENDATIONS ONLY. BECAUSE OF THE MANY VARIABLE CONDITIONS IN AN ACTUAL INSTALLATION, GRAIN SYSTEMS, INC. ASSUMES NO LIABILITY FOR RESULTS ARISING FROM THE USE OF SUCH RECOMMENDATIONS. SITE PREPARATION Foundation Radius Spike Two Feet 2 x 4 Center Stake Pointed Stake Foundation Line Figure #1 1. SELECTING THE PROPER SITE The selected site should be level, firm, and free from underlying debris.
18' Autoflow CIRCULAR FOUNDATION FORM Footing Trench Carpenter's Level Figure #2 3. PREPARE THE FOUNDATION Having scribed the diameter of your foundation, proceed by digging the footing of the foundation. This consists of a large circular trench dug just inside the foundation line. (Refer to foundation details for necessary information.) Once the footing has been dug, you are ready to build the forms. It is important that your form be rigid enough to hold its shape against the poured concrete.
18' Autoflow OCTAGONAL FOUNDATION FORM There are two styles of foundation forms commonly used. The first is the circular form depicted in Figure #2. The second style can be made of 2" x 8" boards set into a square with corners blocked off to form an octagon. (See Figure #3 below.) This eight sided form will approximate a circle and can be constructed quite easily. When the foundation form is completed install reinforcement rods by either welding or wiring in place.
18' Autoflow FROST FREE PAD NOTES: Foundation site should be well drained and free of vegetation or debris. Foundation design is based on a minimum soil bearing capacity of 3,000 lb/ft2. If soil bearing capacity is in doubt, contact a local soil testing engineer. Concrete shall have a minimum compressive strength of 3,000 PSI at 28 days. Requirements for reinforcement do not include overlap. Lap all circumferential bars 35 bar diameters and stagger all laps in plan 3'-0".
18' Autoflow ANCHOR BOLT LAYOUT Refer to following diagram for proper bolt layout. Having poured and leveled the concrete, use the center stake and straight 2" x 4" again to find bolt circle radius for the outside stiffener bolts. Select a starting point and stretch a pre-measured chord along the imaginary circle formed by the bolt circle radius. Consider the placement of these bolts so as not to interfere with the positions of bin doors and transitions.
18' Autoflow HARDWARE/BOLTING REQUIREMENTS NOTE: Grade 2 bolts are designated with a plain head. NOTE: Grade 5 bolts are designated by 3 slash marks on the head. All 5/16" diameter bolts are to be Grade 5 or higher. NOTE: Grade 8 bolts are designated by 6 slash marks on the head. NOTE: Grade 8.2 bolts are designated by 6 slash marks on the head in a sunrise pattern. All 3/8" diameter bolts are to be Grade 8 or 8.2. IMPORTANT: Do not tighten bolts to exceed the torque specifications listed below.

18' Autoflow TOP STIFFENER STARTING LOCATION Refer to Figure #11, for proper location of top stiffeners. On the overlap of the stiffeners, and on the splice, use 3/8" x 1" hex bolts, a washer on the nut side connection. Refer to the stiffener layout, Figure #9, for stiffener usage. All stiffeners are outside the bin wall. Use 5/16" x 3/4" Grade 5 bin bolts with head and neoprene washer to the inside of the bin wall.
18' Autoflow STIFFENER INSTALLATION & LOCATION When installing bottom stiffeners, you may find that in some cases the stiffener with base plate attached will not rest on the foundation (due to unlevel concrete, etc.) Shim plates have been furnished and should be used to fill opening between base plate and concrete. IMPORTANT: If shim plates are not used where required, the downward pressure of the stiffeners will not be transferred directly to the foundation, and bin failure could result. FC-4207516 16 GA.
