20140263927 | SYSTEM AND METHOD FOR FOUNDATIONS FOR ROADSIDE SIGNS AND STRUCTURES - A ground screw anchor foundation for a roadside sign comprises at least one elongated soil screw defining a longitudinal axis. The soil screw includes a barrel section having an upper end and a lower end and a substantially circular cross-section of a first diameter. A point section is connected to the lower end, the point section tapering from a second diameter at a position along the longitudinal axis proximate to the barrel section to a third diameter at a position along the longitudinal axis distal to the barrel section. A helical thread is disposed on an outer surface of at least a portion of the point section. A first component of a breakaway system is mounted on the upper end of the barrel section of the soil screw. The first component is adapted for releasable connection in a breakaway manner to a second component on a roadside sign. | 09-18-2014 |
