Abstract

A PRECAST REPLACING PROCESS WHICH COMPRISES REINFORCING A MAIN FLOOR SLAB GIRDER BY INTRODUCING ENOUGH PRESTRESS TO CAUSE A BENDING MOMENT TO A NEGATIVE DIRECTION OF THE MAIN GIRDER 1, SEQUENTIALLY CUTTING THE FLOOR SLAB 2 PLACED ON THE GIRDER TO PLURAL PIECES OF BLOCKS, SCRAPPING AND REMOVING THE PIECES OF BLOCKS BY MEANS OF A JACK-UP SYSTEM, FOLLOWED BY PLACING THE PRECAST FLOOR SLAB 33 SO THAT CUT-OFF BOX PORTION 35 FORMED THEREON ARE ALLOCATED ON AN UPPER SURFACE OF THE MAIN GIRDER, TEMPORARILY FIXING THE PRECAST FLOOR SLAB AND THE MAIN GIRDER AT THE CUT-OFF BOX PORTIONS WITH A FIXING SPACE LEFT BETWEEN THE CUT-OFF BOX PORTIONS TO THE MAIN GIRDER DIRECTION TO PREVENT LATERAL BACKLING THEREOF, RELEASING SUCH A TEMPORARY FIXTURE AFTER THE PRECAST FLOOR SLAB HAS BEEN PLACED, AND PERMANENTLY FIXING THE MAIN GIRDER AND THE PRECAST FLOOR SLAB WHILE RELEASING THE PRESTRESS INTRODUCED TO THE MAIN GIRDER.
