SLEEVE USED FOR FIXING A REINFORCING BAR, CAPABLE OF PREVENTING REPULSIVE FORCE FROM GENERATING BETWEEN A SLEEVE AND A STEEL BY WELDING A BOLT TO A REINFORCING BAR

摘要

PURPOSE: A sleeve used for fixing a reinforcing bar is provided to prevent sleeve deformation due to stress while welding.;CONSTITUTION: A sleeve used for fixing a reinforcing bar comprises a bolt(110) and a nut(120). The nut comprises a bolt combining unit and a reinforcing bar combining unit for screwing to a reinforcing bar(20). The bolt is welded to a steel(30) when fixing the steel to the reinforcing bar. The screw thread unit of the bolt has a bigger diameter than the reinforcing bar. The bolt combining unit is screwed by the bolt. The inner diameter of the bolt combining unit is bigger than the inner diameter of reinforcing bar combining unit. The bolt comprises a head unit(112) which is welded to the steel. The length of the nut is formed smaller than the length of a part which is equipped with a screw thread on the outer circumference of the reinforcing bar.;COPYRIGHT KIPO 2013
