WIRE DRUM FOR WINDING OF PREFABRICATED WIRE SERIES FOR COMPLETELY PREFABRICATED WIRING METHOD AND PAYING-OUT METHOD OF PREFABRICATED WIRE SERIES FROM WIRE DRUM

摘要

PURPOSE: To prevent the rotation of a wire drum from becoming unstable. ;CONSTITUTION: A plurality of prefabricated wires matching a plurality of tension-resistant section spans forming one stringing section are connected by interposing split wires, and a prefabricated wire series is formed. The prefabricated wire series is wound on a wire drum 21. Partition plates 27 which partition a trunk part 22 into a plurality of regions are installed at the outer circumference of the trunk part 22 for the wire drum 21. A weight 30 is installed at a flange part 23 so as to be detachable. When the prefabricated wire series which has been wound on the wire drum 21 is sent out for a stringing operation, the left-side region of the trunk part 22 becomes an empty region because a wire is sent out as the progress of the stringing operation. In this case, the position of the center of gravity of the wire drum 21 is moved to the right side, and the rotation of the wire drum 21 becomes unstable, Then, when the weight 30 is attached to the flange part 23, the position of the center of gravity of the wire drum 21 is returned to the center side, and the rotation of the wire drum 21 becomes stable and smooth.;COPYRIGHT: (C)1995,JPO
