Abstract
Abstract The disclosure herein describes a structural rod for reinforcing a mass of concrete material, the rod being formed of a non-metallic non-electrically conductive cylindrical core composed of a plurality of fibers oriented in the longitudinal axis and bound to each other by a thermosetting resin; the rod also includes embossments formed of a plurality of continuous fibers helically wound on the core and impregnated with a thermosetting resin; these embossments define a mechanical anchorage with the concrete material.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
18 words
The embodiments of the invention in which an exclusive property of privilege is claimed are defined as follows:
Claim 2
Dependent Claim
88 words
A structural rod for reinforcing a mass of concrete material comprising: a) a non-metallic non-electrically conductive cylindrical core composed of a plurality of continuous fibers oriented substantially in the longitudinal axis and bound to one another by a thermosetting resin; and b) embossment means on said core, being formed of a plurality of continuous fibers helically wound around said core and impregnated with a thermosetting resin; said embossment means defining anchorage a mechanical bound with concrete material when said rod is embedded in said mass of concrete material.
Claim 3
Dependent Claim
21 words
