<P>PROBLEM TO BE SOLVED: To provide a bridge girder delivery method capable of shortening a construction period and reducing reinforcement of a bridge girder and a construction girder. <P>SOLUTION: The bridge girder delivery method is configured such that a construction girder 2 is connected through a connection structure 3 at a rear end part in a delivery direction to a bridge girder 1. The bridge girder 1 is moved on erection equipment 80 by travel devices 71 and 72. After the bridge girder 1 is arranged between corresponding bridge piers 91 and 92, the bridge girder 1 is lowered and installed on the bridge piers 91 and 92. A support column 11 is erected on the connection structure 3, the bridge girder 1 and the construction girder 2 are connected to suspension wires 17 connected to the support column 11 and moved on the erection equipment 80 in the state of being obliquely suspended in front and back directions of delivery. <P>COPYRIGHT: (C)2013,JPO&INPIT |
