About this detail

Gravity column baseplate connections for hollow structural sections, pipe columns, and wide flange columns are supported on concrete foundations. The baseplates are secured with four one-inch diameter anchor rods featuring double nuts and standard washers per schedule. A two-inch diameter grout hole is provided, and a one-and-a-half-inch minimum non-shrink grout layer sits beneath the baseplate above the top of the foundation. A temporary one-eighth inch thick template matching the baseplate size is included for installation alignment and removed prior to column erection. The assembly maintains a three-inch minimum anchor bolt projection above the baseplate and a six-inch minimum concrete cover all around.
