Abstract

Abstract Disclosed is an anchoring apparatus for use in anchoring structures to the ground by use of elongated flexible straps. The anchoring apparatus has a lower ground engaging portion which is embedded in the ground below ground level, and an internally-threaded fastener is provided on the ground-engaging portion. A threaded shaft is releasably attached to the fastener of the ground-engaging portion. An upper portion is attached to the threaded shaft for attaching the straps to the shaft. The upper portion is provided with two anchorheads. Each head has first and second flanges extending at an angle with respect to each other. One of the flanges is provided with a bore through which the shaft extends. The other of the flanges is provided with an elongated slot with a flat-sided bar attached to extend across the slot.
