REINFORCING BAR HAVING PERIODIC PROFILE Russian patent published in 2006 - IPC E04C5/03

Abstract RU 2283929 C1

FIELD: reinforcing elements for reinforced structure reinforcement.

SUBSTANCE: reinforcing bar has core with cross-section shaped as truncated hypocycloid having even number of branches and provided with ribs formed on core surface and inclined towards longitudinal axis thereof. The transversal ribs are located so that the ribs enclose bar core for 160-180°. Transversal rib height in initial hypocycloid branches is 0.01-0.1 of nominal reinforcing bar diameter. Ratio between transversal rib height at hypocycloid apexes and transversal rib height at basic hypocycloid points is 1.0÷5.0.

EFFECT: increased efficiency.
