ABSTRACT:
A ground anchor 20 with stabilizer cap 26 secures above ground objects, such as premanufactured buildings 50, during storms, high winds or ground tremors. The ground anchor has an anchor shaft 22 which is inserted into the ground and at least one auger blade 24 attached to the lower end of the anchor shaft. The auger blade engages the ground and forcibly draws the anchor shaft downwardly into the ground as the anchor shaft is rotated by an installation driver. The circular stabilizer cap 26, having a diameter greater than the auger blade, is mounted concentric to and normal to the upper end of the anchor shaft. Rigidly attached to the stabilizer cap is a skirt 30. The skirt rotates in unison with the anchor shaft, and engages and enters into the undisturbed ground outside the hole made in the ground by the auger blade. A tie down strap 62 connects a winch mount 36, attached to the top of the stabilizer cap, to the premanufactured building. As the tie down strap is tensioned and exerts lateral forces against the ground anchor, lateral support to the ground anchor is provided by the stabilizer cap skirt which is firmly embedded in the undisturbed soil.
