The present invention relates to a prestressing system using hinge-coupling of tensioning members, comprising: a beam (100) installed in a structure in the direction of receiving a bending moment; fixing units (200), each of which having an end hinge portion (210), and which are formed at the respective both ends of the beam (100); a plurality of protruded members (300), each of which having a center hinge portion (310), and which is protruded outwardly from the beam (100); and tensioning members (400), each of which having both ends hinged between end hinge portion (210) and the center hinge portion (310), or between center hinge portions (310), wherein each of the protruded members (300) further has a length adjusting portion (320) for adjusting the degree of protrusion of the center hinge portion (310) from the beam (100). The system of the present invention allows re-tensioning and re-utilization of component and enables tensioning operation and installation of ends of tensioning members to be easily performed. |
