  • Patent number: 6682267
    Abstract: A piering device includes a shaft having a polygonal cross-section with a series of notches spaced at intervals along the vertices of the shaft. For example, the shaft can have a square cross-section with rounded corners. The helical plate has a passageway with a cross-section to slide along the shaft when the helical plate is in a first rotational position on the shaft. However, notches within the passageway of the helical plate engage the notches on the shaft when the helical plate is rotated to a second rotational position, thereby preventing the helical plate from sliding along the shaft. A key is inserted between the shaft and helical plate to hold the helical plate in the second rotational position and thereby fix the axial position of the helical plate on the shaft.

  • Patent number: 6634830
    Abstract: A foundation repair piling made up of segments is post tensioned by a cable fed into the segments after the piling is installed. A cable anchor serves as a base segment of multiple concrete piling segments. After installing all the concrete segments on top of the base segment, a cable is inserted into passages in the segments. The cable is threaded through the completely installed piling segments and into the cable anchor. After the cable bottoms out in the cable anchor, upward tension is applied to the cable. As the cable is pulled, cable lock members in the cable anchor increase gripping pressure even as the cable tension increases, thereby solidly anchoring the end of the cable in the cable anchor. After the desired tension is reached, the cable is terminated at the top of the last segment. The tension is held by a termination lug at the top end of the cable.

  • Patent number: 5890842
    Abstract: A ground anchor includes a planar drive head with a shank extending therefrom. The shank includes a plurality of inline segments with each segment including a cylindrical shaft portion and a cone-shaped tapered portion. The tapered portion of each upstream segment is connected to a shaft portion of an adjacent downstream segment. This relationship presents a plurality of indentations along the length of the shaft. Upon penetration of the shank into the ground, the earth collapses into the indentations which resist withdrawal of the anchor from the ground due to forces acting on the structure secured to the anchor such as a tarpaulin or the like. The planar drive head lies adjacent the ground to preclude above ground interference.

  • Patent number: 5833400
    Abstract: An earth anchor is made from a length of tubing that has angle-cut ends and a pulling attachment pivotally attached to an axle attached across the tubing at right angles to the length of the tubing. The anchor is lowered into an earth bore in a relatively vertical position to be rotated axially via a pull-tension applied to link attached to the pulling attachment. Upward motion causes the anchor to rotate about the axle, burrowing into the surrounding earth until the anchor is lodged in a horizontal position in the earth bore. The link extends to above ground and has a suitable fixture for securing to an object to be anchored. A double-cone effect produced by the compacting action of the angled cut-outs and the continued upward pull via the pull rod, compacts the earth above the anchor in continually expanding cones, and fills the inside of the main body of the anchor with compacted ground.
