FIELD: building, particularly for concrete structures reinforcement. ^ SUBSTANCE: reinforcement rod has core with round cross-section and opened crescens-shaped extensions formed on surface thereof. Tops of adjacent transversal extensions are located in mutually perpendicular axial rod planes. Ratio between maximal height of transversal extension to pitch is 0.12-0.3. Each crescens-shaped extension covers rod circumference part defined by 140°-180° angle. ^ EFFECT: increased adhesion between reinforcement rod and concrete along with maintaining high level of technological effectiveness. ^ 1 cl, 2 dwg |
