<P>PROBLEM TO BE SOLVED: To provide a girder bridge suspension jig capable of installing or removing a girder bridge by attaching the girder bridge suspension jig to the girder bridge without removing an obstacle even when there is the obstacle at the upper part. <P>SOLUTION: A girder bridge suspension jig 10 to be used includes: a horizontal member 11B horizontally disposed between a pair of sidewalls 102A and 102B of a girder bridge; and a crane wire connection member comprising a suspension pulley connection flange 16B supported by the horizontal member 11B and a suspension pulley connection pin insertion hole formed at the suspension pulley connection flange 16B. When the horizontal member 11B of the girder bridge suspension jig 10 is horizontally disposed to the pair of sidewalls, it is suspended by connecting a suspension pulley connection pin 17 to the suspension pulley connection pin insertion hole and a suspension pulley connection pin insertion hole formed at a suspension pulley body 202 suspended from a crane wire 203 so as to be positioned at a height position between the upper ends of the sidewalls 102A and 102B and an almost center position between the sidewalls 102A and 102B. <P>COPYRIGHT: (C)2013,JPO&INPIT |
