About this detail

An existing freestanding switchboard is secured to an existing concrete floor using new structural steel angles welded to the base of the switchboard and anchored with epoxy anchors. A four-inch concrete housekeeping base is anchored to the structural slab with one number four rebar at each corner with minimum three-inch edge coverage, extending three inches into both the slab and the base. Additional anchoring is provided by one-half-inch by six-inch epoxy anchors at the base connection. The steel angle members measure three inches by four inches by one-quarter inch by eight inches long and are painted to match the switchboard color. Approved epoxy anchor systems include Hilti HVA, Hilti HIT, or Ramset Epcon, installed into a concrete slab having a minimum thickness of five inches.
