STRUCTURE OF GIRDER PART FORMED BY SPLIT CONSTRUCTION OF PRESTRESSED CONCRETE MULTIPLE SPAN CONTINUOUS GIRDER STRUCTURE, AND METHOD OF CONSTRUCTING THE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide the structure of a split constructed multiple span continuous girder structure easy in construction, excellent in strength, and capable of assuring a rust prevention effect.;SOLUTION: In this structure of a girder part formed by split constructing a PC multiple span continuous girder structure, a first duct buried with one end opened and positioned and the other end opened and positioned at a connected wall surface with an adjacent PC girder on a secondary construction side is disposed on the lower surface of the rear half part of a prestress (PC) girder on a primary construction side, a pregrout PC steel wire extended forward from a PC pregrout PC steel wire in the PC girder on the secondary construction side is inserted into the duct. In the same manner, the pregrout steel wire is tensely fixed inside the PC girder on the secondary construction side with one end of the first duct used as a fixing side fixed part. The same operations are performed on a third construction side, fourth construction side, etc., for split construction.;COPYRIGHT: (C)2003,JPO
