An expanding anchor and/or pile system wherein an outer shell of the pile/anchor is split lengthwise into at least two pieces and can be placed or driven into a hole in the earth in a retracted state and can subsequently be expanded such that the two or more pieces are forced outwardly—away from one another, thus causing them to exert a lateral force against the sides of the hole and thereby resulting in greater axial load carrying capacity in tension or compression of the anchor/pile.

Provided is a removable ground anchor body using a rotation wherein when a pc strand or a deformed steel bar is rotated, a screw bar is interlock-rotated to raise an operation member and sequentially raise a body and a wedge from the pc strand or the deformed steel bar thereby to release the connection state.

A hybrid permanent anchor is proposed. The hybrid permanent anchor includes: a fixed body disposed between a compression part and a tension part and coupling the compression part and the tension part to each other; the tension part coupled to a front end of the fixed body and transmitting tension to the permanent anchor when tensile stress is generated; the compression part coupled to a rear end of the fixed body and transmitting compressive force to the permanent anchor when compressive stress is generated; a PC steel strand coupled to a rear end of the compression part and having a protective pipe thereon; and an anchor head part fixing the permanent anchor to a structure.

Systems and methods for quickly and securely interconnecting foundation components when axially misaligned without hydraulic tools. Upper to lower leg connections are made with threaded connections or with ball and socket connections that permit angular adjustment. One or more retaining nuts bias the connection to lock it in place at the desired orientation. Foundation component to single-axis tracker connections are facilitated by various wedge and clamp connector assemblies that rely on mechanical engagement to lock components in place and resist axial forces. Other connections are made with hemispherical washers and adapter plates that enable rigid connections through a range of angles.

A structure for anchoring load-bearing posts in a post frame (pole barn) type building on footings in post holes below grade. The structure comprises a flexible cable or similar anchored in or under the footing and extending up through or around the footing to fastening points on opposite sides of a below-ground portion of a post resting on the footing. The footing-anchored cable and the fastening points are then buried in the post hole. A method for constructing the anchor structure is also disclosed.

A guy wire anchoring device is provided which can be used to hold a tower in place. The device features a container which has a plurality of solid side panels, which are connected to two adjacent side panels using a side hinge mechanism. As a result, the container can be reversably moved from an essentially flat, folded orientation, to an expanded empty container orientation when un-folded. The container also includes at least one base plate which is hingeably mounted to the lower edge of at least one side panel of the container, and which can be moved to a position wherein it at least partially closes the opening at the bottom of said empty container. The container is adapted to be filled with a suitable, local material such as sand, aggregate, or the like, in order to increase the weight of the guy wire anchoring device. The device includes a guy wire anchoring bracket to which guy wires can be attached. The device is easily stored, and can be easily transported to the tower location for use as a guy wire anchoring device.
