PURPOSE: A tension frame for manufacturing a prestressed concrete beam girder of pretension type and a method for installing a tendon using the tension frame are provided to complete curing-densification work for manufacturing a beam girder within a short time. CONSTITUTION: A tension frame for manufacturing a prestressed concrete beam girder of pretension type comprises a first wall plate(100), a second wall plate(200), a fixing unit(300), a plurality of tendon guide pipes(400), a one-end support section(150), and other-end support unit. The first and second wall plates are arranged to face each other at an interval. The fixing unit fixes the first and second wall plates together. Both ends of the tendon guide pipes are opened to insert tendons. The one-end support section includes a plurality of one-end support holes(151) in which one end of the tendons are placed. The other-end support unit supports the other end of the tendons.
