[0002]
[Prior art]
When constructing a PC (prestressed concrete) viaduct using a movable support, the process of assembling a girder by temporarily receiving the movable support with a lifting beam installed on the bridge surface is repeated. Since the operation of moving and installing the lifting beam using a crane or truck becomes a critical path in the process, it is necessary to perform the work immediately after the concrete strength reaches the specified value and the PC is tensioned.
[0003]
Conventionally, cranes and trucks installed on bridge surfaces have been used to move, install and remove lifting beams. Also, cranes and trucks were installed on the ground when the pier height was low and sufficient yard was secured on the ground.

By removing the cart positioning angle 37 and the cart positioning angle 61, the lifting beam 1 can freely move in the direction perpendicular to the bridge axis.
[0050]
Next, the trunk portion 75 of the turnbuckle 73 of the bridge axis perpendicular direction positioning device 15 is rotated, and the bolt portion 77 is taken in and out in the direction perpendicular to the bridge axis. When the lifting beam 1 moves in the direction perpendicular to the bridge axis in conjunction with the bolt portion 77, the horizontal pulling roller 13 and the horizontal pulling roller 17 (FIG. 1) rotate to assist the movement of the lifting beam 1.
[0051]
When the position of the lifting beam 1 in the direction perpendicular to the bridge axis is determined, the rotation of the body 75 of the turnbuckle 73 is stopped. After confirming the stop of the rotation of the horizontal pulling roller 13 and the horizontal pulling roller 17 (FIG. 1), the stopper 83 is removed.
[0052]
The gantry 3 and the gantry 5 are moved from the position shown in FIG. 8 to the position shown in FIG. 10 at an appropriate time until the stopper 83 is removed. Then, the lifting beam 1 is lifted using the lifting / lowering jack 11 (FIG. 1) for the gantry 3, and the moving carriage 7 and the moving carriage 9 are moved from the lower side of the lifting beam 1 to another place, and then the lifting is performed. The beam 1 is placed on the gantry 3 and the gantry 5. Note that the winch 23, the pulley 27, the pulley 29, the wire 30, and the like are appropriately removed after towing using the winch 23.
