ABSTRACT:
A foundation system for a mast is installed in the ground with earth anhcors and employs three unitary arms radiating from a central mounting hub. The mast, typically a pipe, is united with the foundation system by a combination clamp and brace which resists high torsion and overturn loading that occurs under high wind conditions. Upper and lower clamping collars are provided by specially configured gusset plates integral with the inner ends of the arms. Each gusset plate on an associated arm has a wing portion welded to the arm and an arcuate portion extending therefrom which partially embraces the mast. An outwardly bent lug on the distal end of each gusset plate is in proximal relationship to the wing of the gusset plate on an adjacent arm, thus the application of drawbolts tightens the plates to form the upper and lower clamping collars and rigidly secure the mast to the system in a vertical orientation.
