PRESTRESSED CONTINUE STEEL-FRAME BRIDGE AND METHOD FOR CONSTRUCTING THEREOF

摘要

The present invention provides a prestressed continuous steel bridge that can be installed by assembling a continuous girder assembly on the piers quickly and stably. The prestressed continuous steel bridge is welded to the end of each girder member constituting the respective girder assemblies of the girder assembly by joining plates joined by mutual fixing bolts on the piers or work platforms of the bridge construction site, and each joining plate. Is formed so as not to protrude above the upper surface of each girder member; It further comprises a turnbuckle for preliminarily holding each unit girder assembly to each corresponding piers, the turnbuckles are provided with two bolt members, one bolt member is one side of the top beam of the top unit pier assembly of the piers It is releasably fixed to one eye bolt fixed to the other bolt member is releasably fixed by the other eye bolt fixed to the lower side of the overlapping means through a connecting line formed with clips at both ends.
