Abstract
A localized fiber reinforcement places strong tensile strength fibers across a hypothetical split line near notches in beams to curtail split propagation caused by cross-grain tension that may otherwise significantly reduce the strength of a beam used as a spanning member. An adhesive coated patch may be applied after a notch is cut in the beam or fibers may be attached to a beam at a factory near the location of an anticipated notching.
Claims3
A field-ready wood beam reinforcement system comprising:
- a flexible fiber patch having at least some fibers running along an axis;
- an adhesive applied to one side of the patch;
- indicia attached to the patch indicating a desired alignment of the patch with wood grain;
- wherein the flexible fiber patch may be applied to a wooden beam with the axis crossing the grain of the wooden beam.
