Bolts shall be spaced not more than 6 feet (1829 mm) on center and there shall be not less than two bolts or anchor straps per piece with one bolt or anchor strap located not more than 12 inches (305 mm) or less than 4 inches (102 mm) from each end of each piece.
Similarly, you may ask, how close can concrete anchors be?
Rule: Concrete fasteners should not be set closer than 10-anchor diameters from each other.
Also to know, how many concrete anchors do I need?
There must be an anchor bolt within 12 inches of each end. And the maximum spacing between any bolts on a single bottom plate is 6 feet. I put my anchor bolts six inches from the end of each bottom plate. Thus a (8 to 12) foot bottom plate would need three (3) anchor bolts.
How to Attach Metal to Concrete Without Screws or Glue
- Drill the metal where you want to anchor it to the concrete.
- Hold the steel in the position that you want to attach it to the concrete.
- Attach a concrete drill bit into a hammer drill.
- Drill a straight hole at each of the anchor locations to the depth of the painter's tape.
