Abstract
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.
Claims18
A method of forming a reinforcing structure onto a form, comprising:
- providing a first length of FRP rebar adjacent to the form so that at least a portion of the FRP rebar is arranged in a spiral against the form at a plurality of locations;
- providing a second length of FRP rebar adjacent to the first length of FRP rebar such that a portion of the first and second lengths form spirals following different paths and conform to the form, wherein the first length and the second length of FRP rebar cross over each other at a plurality of locations and are coupled together at a plurality of said locations;
- and, covering at least a portion of the first and second lengths with a cementitious material.
A reinforced structure comprising:
- an initial form requiring reinforcement;
- a first length of FRP rebar formed into a spiral and contacting the initial form;
- a second length of FRP rebar formed into a second spiral and contacting the initial form;
- wherein portions of the first length of FRP rebar criss-cross portions of the second length of FRP rebar at a plurality of locations;
- and wherein the first length of FRP rebar and second length of FRP rebar are coupled together at a plurality of said locations;
- and,
- a cementitious material covering a substantial portion of the first length and second length of FRP rebar and some of the initial form.
4 more elements
A supporting structure comprising:
- a first spiral of FRP rebar;
- and,
- a second spiral of FRP rebar, wherein portions of the first and second spirals of FRP rebar cross over each other, and wherein some of those portions are coupled together.
