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.

3. The barrier system of claim 2, wherein the flared opening comprises a non-linear taper.

4. The barrier system of claim 1, wherein the strain relief sector extends horizontally from the conduit to reduce stress on the tension cable when the tension cable is displaced by an impact.

5. The barrier system of claim 1, wherein the strain relief sector comprises a recess or groove extending from the conduit.

6. The barrier system of claim 1, wherein each post has a generally planar first face at which the first end of the post'"'"'s conduit is located and a generally planar second face at which the second end of the post'"'"'s conduit is located.

7. The barrier system of claim 6, wherein each post further includes a washer plate disposed on the generally planar second face, where the tension cable comprises a cable termination having a threaded end and wherein the tension cable extends through the washer plates and is bolted in place against the washer plates.

8. The barrier system of claim 1, wherein each post includes at least two of said conduits formed therethrough and said barrier system includes at least two of said tension cables extending between the concrete posts and through the conduits.

9. The barrier system of claim 1, wherein each post has an in-ground base section, an above-ground top section, and a side cover at least partially around the above-ground top section.

10. The barrier system of claim 9, further comprising a wall panel disposed between the first and second concrete posts through which said at least one tension cable extends, wherein the side cover includes an opening for receiving an end of the wall panel.

11. The barrier system of claim 1, further comprising a third reinforced concrete post, wherein the second concrete post is disposed between the first and third concrete posts and includes at least two of said conduits formed therethrough, the system including a second tension cable,

wherein the first tension cable extends between the first concrete post and the second concrete post and terminates on a first side of the second concrete post, and the second tension cable extends between the second concrete post and the third concrete post and terminates on a second side of the second concrete post, wherein the first side of the second concrete post has a strain relief sector formed therein for the second tension cable, and the second side of the second concrete post has a strain relief sector formed therein for the first tension cable.

12. The barrier system of claim 11, wherein the first ends of the at least two conduits of the second concrete post are at about the same vertical height as one another on the first and second sides and a central axis of the conduits cross one another both vertically and horizontally.

13. The barrier system of claim 12, wherein major lengths of the first and second tension cables extending between the first and second concrete posts and between the second and the third concrete posts, respectively, have axes that are coaxial one another.

14. The barrier system of claim 1, further comprising a wall panel disposed between the first and second concrete posts through which said at least one tension cable extends.

15. The barrier system of claim 1, wherein the tension cable has cable termination and cable nut at each end of the cable, wherein each concrete post further comprises a steel washer plate through which the cable end extends and against which the cable nut rests.

16. 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 the non-linearly tapered flared openings reduce stress on the tension cables when the tension cables are displaced by an impact.

17. The barrier system of claim 16, wherein said wall panel is sufficiently free of being anchored to the ground such that upon engagement with the wall panel by a vehicle with sufficient force to displace the tension cables in the direction of the impact a bottom tension cable from the pair of tension cables is displaced about the same amount as a top tension cable from the pair of tension cables.

18. The barrier system of claim 16, wherein the strain relief sector is formed on only one side of the conduit.

19. 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.

20. The method of claim 19, wherein the forming first and second reinforced concrete posts step includes the step of forming a strain relief sector formed therein at the first end of the conduit for reducing stress on the tension cable when the tension cable is displaced by an impact.

21. The method of claim 19, wherein the step of forming first and second reinforced concrete posts includes the step of providing an outer geometric form with an inner form disposed within the outer geometric form, said inner form containing a conduit shaped portion for forming the at least one conduit.

22. 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,
