Two lengths of FRP rebar are formed into spirals and coupled at cross over locations to form a structure to be embedded into a cementitious material or covered in a cementitious material for repairing a form or in new construction.
Claims8
A method of reinforcing a pipe, comprising:
- inserting two lengths of FRP rebar into the pipe so that each length of the FRP rebar is arranged in a spiral under tension, so that it presses against an interior wall of the pipe at a plurality of locations along the interior wall of the pipe, such that the spirals follow different paths and conform to the interior wall of the pipe, wherein the two lengths of the FRP rebar cross over each other at a plurality of locations along the two lengths of the FRP rebar and are coupled together with ties at at least some of the plurality of locations along the length of the rebar;
- and,
- covering at least a portion of the two lengths of the FRP rebar with a cementitious material.
