Zusammenfassung:	PURPOSE: A jacking attachment for tension of prestressed steel materials is provided to induce tension by efficiently using space in a section in which a beam and a pillar or a beam and a wall are connected and where obtaining work space is difficult. CONSTITUTION: A jacking attachment(10) for tension of prestressed steel materials(100) comprises a wedge side support(30), a jacking side support(32), an angle control arm(40), a first and a second angle fixing bar(50,60), a wedge housing(70), and a wedge(80). One end of the wedge side support and one end of the jacking side support are connected to the same shaft by a pivot. One end of the angle control arm is connected to a rotary shaft by the pivot and rotates between the wedge side support and the jacking side support. One end of the first angle fixing bar and one end of the second angle fixing bar are individually connected to the wedge side support and the jacking side support by the pivot, and the other end of the first angle fixing bar and the other end of the second angle fixing bar are connected to the angle control arm.
