Title:
REINFORCING BAR WITH GROOVES
Document Type and Number:
WIPO Patent Application WO/2012/099356
Kind Code:
A2
Abstract:
The present invention provides a reinforcing bar with grooves, in which grooves are further formed on the outer surface of a reinforcing bar, wherein: said grooves are formed in a lengthwise direction of the reinforcing bar and are formed as taper grooves narrow toward a side of an inner part from the outer surface of the reinforcing bar, and protruded portions extended from the taper grooves are further formed, thereby preventing the reinforcing bars from sliding when the reinforcing bars are arranged; coupling power, binding power, and adhesion to the concrete of the reinforcing bars are remarkably improved; thickness and strength are adjusted such that the reinforcing bars can be manufactured in various ways; and since the taper grooves are formed right on the outer surface of the reinforcing bar when the reinforcing bar is manufactured, the reinforcing bar is less discarded and raw materials of the reinforcing bar are saved, thereby a resource-saving effect can be expected when the reinforcing bar is manufactured. To this end, the invention provides a reinforcing bar that: comprises, on the outer surface of said reinforcing bar (10), taper grooves (11) which are lengthily recessed in a lengthwise direction of said reinforcing bar (10), wherein the taper grooves (11) are narrowed toward a side of an inner part from the outer surface of the reinforcing bar (10); and further comprises protruded portions (12) which are extended from the taper grooves (11) between said taper grooves (11). Further, on the outer side of said taper grooves (11) and said protruded portions (12), auxiliary protruded portions (13) are further comprised to wind and put each of the taper grooves (11) and the protruded portions (12) thereon.
