REINFORCING WIRE WITH SPIRAL PROFILE Russian patent published in 2021 - IPC E04C5/03 

FIELD: construction materials.

SUBSTANCE: invention can be used in the production of prestressed reinforcement for reinforcing concrete products and provides the highest possible adhesion to concrete in any potentially possible direction of displacement, a high level of specific strength, relaxation and fatigue resistance. In a reinforcing wire with a spiral profile, three ruled surfaces are applied on the surface along a helical line, separated by sections of a cylindrical surface. On the ruled surfaces, trapezoidal projections are located at an angle in the direction opposite to the direction of the helical line of the arrangement of the ruled surfaces themselves.

EFFECT: extension of the range of solutions for concrete reinforcement.
