STRUCTURE FOR REINFORCING TENSILE STRESS OF TENDON ANCHORAGE

摘要

PURPOSE: A reinforcement structure for preventing the tensile disruption of the tendon anchoring part of concrete is provided to effectively restrict internal concrete using a spiral re-bar with a continuous closed structure. CONSTITUTION: A reinforcement structure for preventing the tensile disruption of the tendon anchoring part of concrete comprises an anchor plate (10), a tendon (20), and a reinforcing material. The reinforcing material includes a spiral bar (31), a horizontal bar (32), and a lower support (33). The horizontal bar is welded to both inner circumferences of the spiral bar in the longitudinal direction. The lower part of the spiral bar is welded with the lower support. The tendon is supported in the horizontal bar as a reinforcement structure is anchored on the bottom using the lower support and the spiral and horizontal bars are alternated with the tendon.
