The present invention relates to a composite girder with a lightweight long-span structure in which a truss part made of a metal material in the center of the span and a concrete part formed of a prestressed and precast concrete member is integrally coupled to both sides of the length direction, a method for constructing the same, and an end part attaching plate used for the construction method. Provided are a composite girder, a method for constructing the same, and an end part attaching plate used for the construction method, wherein the composite girder comprises a truss part (1) located in the center in the longitudinal direction and a precast concrete part (2) assembled and coupled on each longitudinal end of the truss part (1) and has a structure in which an anchoring member (130) is provided in a lower chord (13), an end part attaching plate (3) having a protruding coupling material (36) is integrally formed in the attachment end surface of the precast concrete part (2), the truss part (1) is attached to the precast concrete part so that the protruding coupling material (36) is integrally coupled to the lower chord (13), the precast concrete part in which a tensile attachment tendon (7) is penetrated and arranged is fixated to the anchoring member (130) of the lower chord (13) in the tensed state, and a continuous tendon (6) is arranged in the longitudinal direction over the precast concrete part and the truss part while coupled to the lower chord (13) of the truss part (1) to introduce tension. |
