Anchor Bolt Charts
Prior to setting any anchor bolts, you must be sure to have the correct anchor bolt placement. This is very
critical for stiffener alignment during bin erection.
NOTE:
Refer to proper chart to find the anchor chord dimensions that correspond to the bin that is being
built.
Scribe the radius location of the anchor bolts by using a center stake and a straight 2 x 4. Along the
scribed radius, start with one anchor bolt and work counterclockwise to locate one quarter of the anchor
bolts then clockwise to locate another quarter of the anchor bolts. Working off of the last anchor bolts in
each quarter, locate the remaining anchor bolts in the last two quarters.
