JOINT STRUCTURE OF DEFORMED STEEL BARS FOR REINFORCED CONCRETE

摘要

PURPOSE: A joint structure of deformed steel bars for reinforced concrete is provided to increase the strength and stiffness on a joint. CONSTITUTION: The joint structure of deformed steel bars for reinforced concrete comprises the steps of forming beads on one or more joints(110) of the end of a deformed steel bar(100) to have the same height as the joint by arc welding, forming incomplete screws(150) on a joint(110) and a rib(120) adjacent to the beads of a complete screw(140) respectively, and coupling the deformed steel bar(100) to a coupler(200) by the complete screw(140) and the incomplete screw(150).
