Abstract
A post foundation system is provided. The system has a shaft with a helical disk attached to one end and a post support attached to the other end. The helical disk drives the shaft into the ground as a rotational force is applied to the shaft. A fin section is rotatably coupled about the shaft between its first and second ends. The fin section can have one or more fins extending outwardly from the shaft. The fin section engages the ground to stabilize the post foundation system as the shaft of the post foundation system is driven into the ground.
Claims15
A post foundation system, comprising:
- a shaft having a first and a second end;
- a helical disk affixed to the first end of the shaft;
- a sign post slip joint base affixed to the second end of the shaft having an opening for receiving a sign post within the shaft;
- a movable sleeve carried by the shaft between the second end of the shaft and the helical disk, and,
- at least one fin carried by the sleeve.
A post foundation system, comprising:
- a tubular shaft having a first and a second end;
- a helical disk affixed to the first end of the shaft;
- a retainer ring affixed to the shaft;
- a sign post slip joint base affixed to the second end of the shaft, the sign post slip joint base having an opening for receiving a sign post within the shaft;
- a sleeve carried by the shaft between the retainer ring and the first end of the shaft, the retainer ring retains the sleeve at a predetermined longitudinal position from the second end of the shaft, and,
- at least one fin carried by the sleeve.
A post foundation system, comprising:
- a tubular shaft having a first and a second end;
- a helical disk affixed to the first end of the shaft;
- a retainer ring affixed to the shaft, the retainer ring affixed to the shaft is closer to the second end of the shaft than it is to the first end of the shaft;
- a sign post slip joint base affixed to the second end of the shaft, the sign post slip joint base having an opening for receiving a sign post within the shaft;
- a rotatable sleeve carried by the shaft between the retainer ring and the first end of the shaft, the retainer ring retains the rotatable sleeve at a predetermined longitudinal position from the second end of the shaft, wherein the tubular shaft will rotate within the rotatable sleeve when the sleeve is held stationary, and,
- at least one fin carried by the sleeve.
