Link-plate connection for monopole reinforcing bars
Reinforcing bars include load transfer connectors. A link plate includes openings that mate with the load transfer connectors to overlie the splice between reinforcing bars being spliced. A cover plate may be fastened over the link plate.
1. A system configured to reinforce a monopole, the system comprising:
a first reinforcing bar having an inner, monopole-engagement surface and an outer surface, the inner and outer surfaces of the first reinforcing bar spaced from one another along a first direction;
a first generally rectangular load transfer connector disposed on the outer surface of the first reinforcing bar that extends out from the outer surface of the first reinforcing bar;
a second reinforcing bar having an inner, monopole-engagement surface and an outer surface, the inner and outer surfaces of the second reinforcing bar spaced from one another along the first direction;
a second generally rectangular load transfer connector disposed on the outer surface of the second reinforcing bar that extends out from the outer surface of the second reinforcing bar; and
a link plate configured to overlay at least a portion of each of the first reinforcing bar and the second reinforcing bar, the link plate defining first and second openings configured to mate with the first and second load transfer connectors, respectively, when the link plate overlays the at least a portion of each of the first and second reinforcing bars.
2. The system of claim 1 , wherein the first and second openings are configured to mate with the first and second load transfer connectors, respectively, when the first and second reinforcing bars are arranged end-to-end.
3. The system of claim 1 , wherein each of the first and second reinforcing bars has a first end, and a second end offset from the first end along a second direction, perpendicular to the first direction, and the first and second openings are configured to mate with the first and second load transfer connectors, respectively, when the second end of the first reinforcing bar is disposed adjacent to the first end of the second reinforcing bar.
4. The system of claim 3 , wherein the first load transfer connector extends from the first reinforcing bar at a location that is closer to the second end of the first reinforcing bar than the first end of the first reinforcing bar.
5. The system of claim 4 , wherein the second load transfer connector extends from the second reinforcing bar at a location that is closer to the first end of the second reinforcing bar than the second end of the second reinforcing bar.
6. The system of claim 4 , further comprising a third load transfer connector, wherein the third load transfer connector extends out from the outer surface of the first reinforcing bar at a location that is between the first load transfer connector and the second end of the first reinforcing bar.
7. The system of claim 3 , wherein the first reinforcing bar defines at least one aperture configured to receive at least one fastener therethrough and into the monopole so as to secure the first reinforcing bar to the monopole.
8. The system of claim 7 , wherein the first load transfer connector extends from the first reinforcing bar at a location that is between the at least one aperture of the first reinforcing bar and the second end of the first reinforcing bar.
9. The system of claim 7 , wherein the second reinforcing bar defines at least one aperture configured to receive at least one fastener therethrough and into the monopole so as to secure the second reinforcing bar to the monopole.
10. The system of claim 9 , wherein the second load transfer connector extends from the second reinforcing bar at a location that is between the at least one aperture of the second reinforcing bar and the first end of the second reinforcing bar.
11. The system of claim 1 , further comprising a cover plate configured to overlay at least a portion of the link plate.
12. The system of claim 1 , wherein the first and second openings of the link plate are configured to mate with the first and second load transfer connectors, respectively, with an interference fit.
13. The system of claim 1 , wherein the first load transfer connector is formed integrally with the first reinforcing bar.
14. A method for reinforcing a monopole, the method comprising:
installing a reinforcement system onto the monopole such that first and second reinforcing bars of the reinforcement system are fastened to the monopole, a link plate of the reinforcement system overlies at least a portion of each of the first and second reinforcing bars, a first opening in the link plate mates with a first generally rectangular load transfer connector disposed on the outer surface of the first reinforcing bar that extends from the first reinforcing bar, and a second opening in the link plate mates with a second generally rectangular load transfer connector disposed on the outer surface of the second reinforcing bar that extends from the second reinforcing bar.
15. The method of claim 14 , wherein the installing step comprises a step of fastening the first and second reinforcing bars to the monopole.
16. The method of claim 15 , wherein the fastening step comprises fastening the first and second reinforcing bars to the monopole such that a second end of the first reinforcing bar is adjacent a first end of the second reinforcing bar, the first load transfer connector is closer to the second end of the first reinforcing bar than a first end of the first reinforcing bar, and the second load transfer connector is closer to the first end of the second reinforcing bar than a second end of the second reinforcing bar.
17. The method of claim 14 , wherein the installing step comprises a step of overlaying the link plate over at least a portion of each of the first and second reinforcing bars such that the first opening mates with the first load transfer connector and such that the second opening mates with the second load transfer connector.
18. The method of claim 14 , wherein the installing step comprises installing the reinforcement system to the monopole such that a cover plate overlays at least a portion of the first and second openings.
19. The method of claim 14 , wherein the installing step comprises overlaying a cover plate over at least a portion of the first and second openings.
