  • Prestressed concrete poles with internal bolting and leveling structures
    Patent number: 5819487
    Abstract: A prestressed concrete pole is internally mounted to a pre-existing foundation and may be vertically aligned or leveled with the foundation. The pole has an internal cavity in its base which includes an internal baseplate disposed above the bottom of the pole. The baseplate axially compresses the pole in combination with prestressing cables. An adjusting plate is attached to the baseplate and includes holes for accepting anchor bolts extending vertically from the foundation. An access window is provided between the baseplate and adjusting plate to enable an installer to adjust fasteners on the anchor bolts below the plates. By adjusting the upper and lower fasteners on the anchor bolts, the pole can be leveled.
