1. A barrier system comprising:
- at least first and second reinforced concrete posts, each concrete post including at least one conduit formed therethrough having first and second ends and a strain relief sector formed therein at the first end of the conduit; and
at least one tension cable extending between the posts, the tension cable extending through the conduit of each post and having a cable end secured to the post at the second end of each post'"'"'s conduit,wherein the strain relief sector comprises a groove formed in the concrete post, the groove intersecting the conduit proximate the first end thereof, the groove extending laterally from the conduit in an impact direction and defining a smooth, outwardly curved surface extending from the conduit and positioned such that the tension cable is received within the groove when displaced by an impact in the impact direction.

Abstract
A barrier system includes at least first and second reinforced concrete posts, each concrete post including at least one conduit formed therethrough having first and second ends and a strain relief sector formed therein at the first end of the conduit. At least one tension cable extends between the posts. The tension cable extends through the conduit of each post and has a cable end secured to the post at the second end of each post'"'"'s conduit.

12. A barrier system comprising:
-
at least first and second rebar skeleton reinforced concrete posts, each reinforced concrete post comprising an in-ground anchor post portion and an above-ground post portion, wherein the in-ground anchor post has a height greater than a height of the above-ground post portion, the above-ground post portion comprising at least two vertically spaced conduits formed therethrough, wherein the conduits each have first and second ends, the above-ground post portion having a non-linearly tapered flared opening to the conduit first end; a pair of vertically spaced tension cables extending between the reinforced concrete posts, the tension cables having cable terminations at ends thereof, the tension cables extending through the conduits of each post; means connected to said cable terminations for anchoring the tension cables to the reinforced concrete posts at the second end of each conduit; and a wall panel disposed between the first and second reinforced concrete posts through which the tension cables extend, wherein each of the non-linearly tapered flared openings extends from only one side of a respective conduit in an impact direction, the non-linearly tapered flared openings configured to reduce stress on the tension cables when the tension cables are displaced by an impact in the impact direction. - View Dependent Claims (13)

14. A method of constructing a barrier system, comprising:
-
forming first and second reinforced concrete posts in situ, each concrete post having a below-ground anchor portion and an above-ground portion, the above-ground portion including at least one conduit formed therethrough having first and second ends; connecting at least one tension cable between the posts, the tension cable extending through the conduit of each post and having a cable end secured to the post at the second end of each post'"'"'s conduit; and after the connecting step, forming in situ a wall panel around the tension cable between the first and second reinforced concrete posts. - View Dependent Claims (15, 16)

17. A barrier system comprising:
-
first and second reinforced concrete posts and an intermediate reinforced concrete post disposed therebetween, each reinforced concrete post comprising an in-ground anchor post portion and an above-ground post portion, a first wall panel extending between the first reinforced concrete post and a first side of the intermediate reinforced concrete post, and a second wall panel extending between the second reinforced concrete post and a second side of the intermediate reinforce concrete post; a first pair of vertically spaced tension cables, including first and second tension cables, extending through the first wall between the first reinforced concrete post and the intermediate reinforced concrete post, and a second pair of vertically spaced tension cables, including third and fourth tension cables, extending through the second wall between the second reinforced concrete post and the intermediate reinforced concrete post, wherein within the first and second walls the first and second tension cables have axes that are coaxial with axes of the third and fourth tension cables, respectively, first, second, third and fourth cable terminations disposed on a respective first end of each of the first, second, third and fourth tension cables; wherein the above-ground post portion of the intermediate reinforced concrete post has a first pair of vertically spaced parallel conduits formed therethrough, including first and second conduits extending from the first side to the second side thereof, and a second pair of vertically spaced parallel conduits formed therethrough, including third and fourth conduits extending form the first side to the second side, wherein the first and second tension cables extend through the first pair of spaced parallel conduits and are secured by their cable terminations to the intermediate reinforced concrete post at the second side of the intermediate reinforced concrete post and the third and fourth tension cables extend through the second pair of spaced parallel conduits and are secured by their cable terminations to the intermediate reinforced concrete post at the first side of the intermediate reinforced concrete post, and wherein the first pair of conduits and second pair of conduits crisscross one another, the conduits each being oriented obliquely both in the horizontal and vertical planes with respect to the axes of the tension cables. - View Dependent Claims (18)
