Abstract
A post anchor system for embedded posts has a plurality of post anchors formed preferably of a non-metallic material. Each anchor has a tubular main sleeve with interior splines to engage the post. A disc member extends horizontally from a midlength position on the sleeve and upper and lower radial fin members extend from the sleeve and are also joined to the disc. The fin members are positioned at space locations relative to one another so as to present maximum resistance to movement of the embedded post in the earth.
Claims3
A post anchor formed of non-metallic material for use with an elongated post having a portion embedded in the earth, the post anchor comprising:
- a main sleeve portion having an inner sleeve surface and an outer sleeve surface, and having a top end and a bottom end;
- a series of radially spaced, elongated, inwardly projecting, vertical splines on the inner sleeve surface;
- a substantially flat horizontal disc member extending from the outer sleeve surface at a midlength location between the top and bottom ends of the sleeve;
- the disc member having a peripheral vertical flange extending about the perimeter thereof;
- a plurality of lower radial fin members extending from the outer sleeve surface, the fin members having outer edges coextensive with the flange, and lower edges coextensive with the bottom end of the main sleeve portions;
- a plurality of upper radial fin members extending from the outer sleeve surface, at locations intermediate the locations of the lower fin members, the upper fin members having vertical edges coextensive with the flange, and upper edges coextensive with the top of the main sleeve, the upper fins having rigidifying vertical braces incorporated therein adjacent the vertical edges thereof;
- strengthening ribs on the outer sleeve surface extending from the disc members to the top of the main sleeve portions;
- the post anchors being adapted to be engaged on the portion of the post embedded in the earth with the vertical splines and frictional engagement therewith such that the fins resist lateral movement in the earth of the post.
The combination, with a fence post to be embedded in the earth, of a pair of post anchors, each comprising:
- a main sleeve portion having an inner sleeve surface and an outer sleeve surface, and having a top end and a bottom end;
- a series of radially spaced, elongated, inwardly projecting, vertical splines on the inner sleeve surface;
- a substantially flat horizontal disc member extending from the outer sleeve surface at a midlength location between the top and bottom ends of the sleeve;
- the disc member having a peripheral vertical flange extending about the perimeter thereof;
- a plurality of lower radial fin members extending from the outer sleeve surface, the fin members having outer edges coextensive with the flange, and lower edges coextensive with the bottom end of the main sleeve portions;
- a plurality of upper radial fin members extending from the outer sleeve surface, at locations intermediate the locations of the lower fin members, the upper fin members having vertical edges coextensive with the flange, and upper edges coextensive with the top of the main sleeve, the upper fins having rigidifying vertical braces incorporated therein adjacent the vertical edges thereof;
- strengthening ribs on the outer sleeve surface extending from the disc members to the top of the main sleeve portions;
- the post anchors being adapted to be engaged on the portion of the post embedded in the earth with the vertical splines in frictional engagement therewith such that the fins resist lateral movement in the earth of the post;
- the first of the post anchors being engaged about one end of the post and the second of the post anchors being engaged about the post at a locations spaced upwardly of the first post anchor.
