Anchor Bolt Placement
Having poured and leveled the concrete, use the center stake and straight 2" x 4" again to find the bolt
circle radius for the outside hold-down brackets. Select a starting point and stretch a pre-measured chord
along the imaginary circle formed by the bolt circle radius. Take into consideration the placement of these
bolts so as not to interfere with the positions of bin doors and transitions. (Refer to below
Chart for
necessary radius and chord lengths.) Take the time and work carefully since accuracy is important.
Work both directions from first anchor bolt location, this will help eliminate possible error in laying out
anchor bolts. On larger bins sight across starting anchor bolt and center pin and place anchor bolt on
opposite side of anchor bolt radius. From this point you can work both directions from both anchor bolts.
NOTE: Top edge of slab where the bin wall sets must be held to within 1/8" of level.
