Single anchor terminal

1. A single anchor terminal comprising:

a release post having opposite first and second faces;

a cable having an end portion releasably coupled to the release post, the cable extending from the release post in a first direction;

a pair of notched plates disposed on the opposite first and second faces of the release post, each notched plate having laterally opening notches disposed along opposite side edges of each notched plate, wherein the end portion of the cable is received in the notches;

a brace supporting the release post in an upright position, the brace extending from the release post in a second direction opposite the first direction, the brace comprising a first portion attached to the release post and a second portion coupled to the first portion with a release component; and

an anchor base comprising a main post supporting the release post and a brace anchor coupled to the main post, wherein the second portion of the brace is coupled to the brace anchor.

2. The single anchor terminal of claim 1 further comprising a pair of keeper plates disposed adjacent the notched plates, wherein the cable extends through openings in the keeper plates.

3. The single anchor terminal of claim 2 wherein the keeper plates are breakable in response to a load being applied by the cable.

4. The single anchor terminal of claim 1 further comprising a shear strap attached to the anchor base and engaging the release post, wherein the shear strap restrains movement of the release post relative to the anchor base in the first direction.

5. The single anchor terminal of claim 1 , wherein the laterally opening notches comprise upwardly sloped edges and downwardly sloped edges.

6. The single anchor terminal of claim 1 , wherein the release post is inclined in the second direction towards the brace relative to a vertical axis.

7. The single anchor terminal of claim 1 further comprising first, second and third cables each having end portions releasably coupled to the release post and extending from the release post in the first direction.

8. The single anchor terminal of claim 1 wherein the end portions of the first, second and third cables are coupled to the release post at first, second and third locations, and wherein the first portion of the brace is attached to the release post at a fourth location, wherein the first, second and third locations are positioned below the fourth location.

9. The single anchor terminal of claim 1 wherein the release post is releasably connected to the main post of the anchor base.

10. A single anchor terminal comprising:

a release post;

a cable having an end portion releasably coupled to the release post, the cable extending from the release post in a first direction;

a brace supporting the release post in an upright position, the brace extending from the release post in a second direction opposite the first direction, the brace comprising a first portion attached to the release post and a second portion coupled to the first portion with a release component, wherein the release component comprises a catch and an indent formed in adjoining ends of the first and second portions of the brace, wherein the catch of the first portion interlocks with and directly engages the indent in the second portion and the catch of the second portion interlocks with and directly engages the indent in the first portion; and

an anchor base comprising a main post supporting the release post and a brace anchor coupled to the main post, wherein the second portion of the brace is coupled to the brace anchor.

11. The single anchor terminal of claim 10 , wherein:

the release component further comprises a fastener coupling the adjoining ends of the first and second portions of the brace.

12. The single anchor terminal of claim 10 , wherein:

the catch of each of the first and second portions of the brace comprises an inclined edge and a perpendicular edge relative to longitudinal axes of the first and second portions;

the indent of each of the first and second portions comprises an inclined edge and a perpendicular edge relative to the longitudinal axes of the first and second portions;

when a tensile force applied along the longitudinal axes of the first and second portions, the perpendicular edge of the catch of the first portion is configured to abut the perpendicular edge of the indent of the second to provide resistance against the tensile force; and

when a compressive force is applied along the longitudinal axes of the first and second portions, the inclined edge of the catch of the first portion is adapted to slip against the inclined edge of the indent of the second portion to decouple the adjoining ends of the first and second portions of the brace.

13. A method for installing a single

anchor terminal, the method comprising:

attaching a brace anchor to a main post of the single anchor terminal, the brace anchor forming a truss extending from the main post;

installing at least a portion of the brace anchor and the main post above grade;

supporting a release post having opposite first and second faces on the main post;

supporting the release post in an upright position by inserting a brace between the release post and the brace anchor, wherein inserting the brace comprises coupling a first portion of the brace to the release post and coupling a second portion of the brace to the above grade portion of the brace anchor;

disposing a pair of keeper plates at the opposite first and second faces of the release post, each keeper plate having openings to receive an end portion of a cable;

disposing a pair of notched plates adjacent the keeper plates to align laterally opening notches disposed along opposite sides edges of the notched plates with the openings of the keeper plates; and

extending the end portion of the cable through the openings and

adjoining the first and second portions of the brace being with a release component.

14. The method of claim 13 further comprising:

applying tension along the cable in a first direction, the brace anchor extending from the main post in a second direction opposite the first direction; and thereby applying tension along longitudinal axes of the first and second portions of the brace.

15. A single anchor terminal comprising:

a release post;

a cable having an end portion releasably coupled to the release post, the cable extending from the release post in a first direction;

a brace supporting the release post in an upright position, the brace extending from the release post in a second direction opposite the first direction, the brace comprising a first portion attached to the release post and a second portion coupled to the first portion with a release component; and

an anchor base comprising a main post supporting the release post and a brace anchor coupled to the main post, wherein the second portion of the brace is coupled to the brace anchor; wherein the brace anchor comprises a first end connected to the main post below grade, and wherein the brace anchor extends upwardly from the first end and has a second end positioned above grade, wherein the second portion of the brace is coupled to the second end of the brace anchor, and further comprising a strut coupled to the main post and to the brace anchor between the first and second ends of the brace anchor.

16. The single anchor terminal of claim 15 wherein the brace anchor forms a 45 degree angle with the main post.

17. The single anchor terminal of claim 15 wherein the strut is positioned below grade.
