Abstract:
A support anchor for supporting in the ground an above ground structure comprising:an elongate shaft having an upper end and a lower end,a screw flight rigidly coupled to the shaft at the lower end of the shaft for rotation therewith such that the screw flight is screwed into the ground with the shaft standing upwardly in the ground;the shaft including at least a portion thereof which is non circular and shaped such that the shaft can be grasped at the portion and rotated to drive the screw flight into the ground;a male screw thread member at the upper end of the shaft projecting upwardly from the ground;a mounting member for mounting on an upper end of the male screw thread member for supporting the above ground structure on the shaft;a stabilizer member separate from the shaft including a sleeve portion shaped to closely surround the shaft for sliding movement therealong, said sleeve portion being shaped in cross section to co-operate with the non-circular portion of the shaft prevent rotational movement of the shaft relative to the sleeve portion and a plurality of wing members rigidly connected to said sleeve portion and extending substantially radially outwardly therefrom at angularly spaced locations therearound with each wing member shaped such that the wing members engage into the ground as the stabilizer member is forced into soil surrounding the shaft;the stabilizer member, with the stabilizer member installed on the shaft in the ground and with the mounting member installed on the male screw thread member, being free to float both upwardly and downwardly along the shaft.
