Abstract

A reinforcement system includes a structural member such as a concrete wall including a pair of holes formed therein. A fiber reinforcement strip is adhered to the structural member between the pair of holes. A U-shaped bracket includes a pair of legs being adhered in the pair of holes and a bridge portion that overlaps the fiber reinforcement strip, wherein the first end of the fiber reinforcement strip is wrapped around the bridge portion and adhered to an intermediate portion of the fiber reinforcement strip.

Claims

1. A wall reinforcement system, comprising:

a wall structure including a pair of holes formed therein;

a fiber reinforcement strip adhered to the wall structure between the pair of holes, the fiber reinforcement strip having a first end, a second end and an intermediate portion disposed between the first and second ends; and

a U-shaped bracket having a bridge portion disposed between a pair of legs, the pair of legs being adhered within the pair of holes by an adhesive and the bridge portion overlapping the fiber reinforcement strip, wherein the first end of the fiber reinforcement strip is wrapped around the bridge portion and adhered overtop a region of the intermediate portion of the fiber reinforcement strip.

2. The wall reinforcement system according to claim 1, wherein the fiber reinforcement strip is made from carbon fibers.

3. The wall reinforcement system according to claim 1, wherein the bracket is made from carbon fibers.

4. The wall reinforcement system according to claim 1, wherein the bracket is made from metal.

5. A method of reinforcing a structure, comprising the steps of:

forming a pair of holes in the structure;

adhering a fiber reinforcement strip to the structure between the pair of holes, the fiber reinforcement strip having a first end, a second end and an intermediate portion disposed between the first and second ends;

injecting adhesive into the pair of holes; and

providing a bracket having a bridge portion and a pair of legs extending from opposite ends of the bridge portion, and inserting the pair of legs into the pair of holes with the bridge portion overlapping the fiber reinforcement strip and the first end of the fiber reinforcement strip wrapped around the bridge portion and positioned in overlapping relation to a region of the intermediate portion of the fiber reinforcement strip, wherein the bridge portion has a width that is wider than a width of the pair of legs.

6. The method according to claim 5, wherein the fiber reinforcement strip is made from carbon fibers.

7. The method according to claim 5, wherein the bracket is made from carbon fibers.

8. The method according to claim 5, wherein the bracket is made from metal.

9. A method of reinforcing a structural member, comprising the steps of:

forming a pair of holes at a base of the structural member;

adhering a fiber reinforcement strip from the base of the structural member to a top of the structural member between the pair of holes, the fiber reinforcement strip having a lower end, an upper end and an intermediate portion disposed between the upper and lower ends;

injecting an adhesive into the pair of holes;

providing a bracket having a bridge portion and a pair of legs extending from opposite ends of the bridge portion, and inserting the pair of legs into the pair of holes with the bridge portion overlapping the fiber reinforcement strip; and

folding the lower end of the fiber reinforcement strip around the bridge portion of the bracket and adhering the lower end of the fiber reinforcement strip to the intermediate portion of the fiber reinforcement strip.

10. The method according to claim 9, wherein the fiber reinforcement strip is made from carbon fibers.

11. The method according to claim 9, wherein the bracket is made from carbon fibers.

12. The method according to claim 9, wherein the bracket is made from metal.

13. A method of reinforcing a structure, comprising the steps of:

forming a pair of holes in the structure;

adhering a fiber reinforcement strip to the structure between the pair of holes, the fiber reinforcement strip having a first end, a second end and an intermediate portion disposed between the first and second ends;

injecting adhesive into the pair of holes;

providing a bracket having a bridge portion and a pair of legs extending from opposite ends of the bridge portion, and inserting the pair of legs into the pair of holes with the bridge portion overlapping the fiber reinforcement strip; and

folding the first end of the fiber reinforcement strip around the bridge portion of the bracket and adhering the first end of the fiber reinforcement strip to the intermediate portion of the fiber reinforcement strip.

14. The method according to claim 13, wherein the fiber reinforcement strip is made from carbon fibers.

15. The method according to claim 13, wherein the bracket is made from carbon fibers.

16. The method according to claim 13, wherein the bracket is made from metal.
