Abstract

The present invention relates to a prestressing system using screw joining, 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); a plurality of hinge members (400), each of which having one end hinge-coupled to one side of the end hinge portion (210) and hinge-coupled to both sides of the center hinge portion (310); and a plurality of joint members (500) screw-joined to the other ends of the hinge members (400). The prestressing system of the present invention is installed in such a manner that the line formed by connecting the hinge members (400) and the joint members (500) is curved or bent to allow the middle portion of the connection to be protruded farthest from the beam (100), and prestressing force is applied to the beam (100) by the screw-joining of the joint members (500). The system of the present invention allows re-tensioning and re-utilization of components and enables tensioning operation and installation of ends of tensioning members to be easily performed.
