Title:
RIBBED REINFORCING BAR
Document Type and Number:
WIPO Patent Application WO/2018/117916
Kind Code:
A3
Abstract:
The invention is directed toward the creation of a ribbed reinforcing bar without longitudinal ribs, which provides improved reinforcement for reinforced concrete structures and can also be used as a ground anchor and as a fastening element for formwork and other mechanical connecting and anchoring devices. This technical result is achieved in that a ribbed reinforcing bar has a core with a circular cross section, and inclined crescent-shaped transverse protuberances arranged in four rows over the surface of the bar. In order to allow two-high rolling without the formation of longitudinal ribs, the peaks of the transverse protuberances are arranged in a checkerboard fashion along a spiral line over the entire surface of the core. The peaks of adjacent longitudinal rows of transverse protuberances are situated in inclined axial planes of the bar which lie at angles of from 20° to 70° adjacent to axial planes which coincide with the rolling planes of the bar. The protuberances can be arranged on the surface of the bar such as to form a spiral thread.
