GIRDER ERECTING METHOD ACCORDING TO DIVIDED GIRDER DOUBLE DRAWING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a girder erecting method for erecting girder without using erection nose.;SOLUTION: According to the girder erecting method, a plurality of lower structures 2, 3, 4 are serially constructed at intervals on both sides of a girder erection scheduled area, and one of divided girders 8a is slidably arranged over the plurality of lower structures 2, 3 on one lateral side of the girder erection scheduled area, followed by slidably arranging the other divided girder 8b over the plurality of lower structures 2, 3 on the other lateral side of the same. Then the one divided girder 8a and the other divided girder 8b opposed to each other are connected together by a drawing prestressing steel via a drawing jack, and the one divided girder 8a and the other divided girder 8b are drawn in mutually approaching directions and then jointed together.;COPYRIGHT: (C)2006,JPO&NCIPI
