Epoxy Anchor Bolts/Hold-downs
What are they?
Epoxy anchors or chemical anchors are installed in concrete footings for the purpose of securing the shear wall to the footing.
What do Epoxy Hold-downs do?:
Epoxy Anchor Bolts and Hold downs do just that, resist a load applied in tension such as a lift from an earthquake’s seismic wave. The two cartridges in each capsule contain one, a hardener and two, a resin. When the two are run through the mixing nozzle the hardener will activate the resin bonding to the all-thread anchor and cleaned drilled hole.
Anchor bolts are located as the code requires, usually every 4ft, serving as shear strength for the load bearing wall. Hold downs and anchor bolts work together to keep the shear wall anchored and held down into the footing. Seismic waves, earthquakes rapidly lift and move laterally the earth material.
