<P>PROBLEM TO BE SOLVED: To provide a device for tightly stretching and supporting a wire rod which allows an anchor clamp to move from a horizontal direction to a vertical direction while making the tension of a transmission line constant in a prefabricated wiring method for extending a transmission line between transmission towers. <P>SOLUTION: A slide member 301, which includes two grooved pulleys 312, 322, slides an L-shaped rail part 200A of a support device main body 200 provided in a transmission tower member 100, integrally with an anchor clamp interposed between the two grooved pulleys 312, 322. Thereby, a distance of movement of a feed-side transmission line and a distance of movement of a lead-in-side transmission line becomes equal, and movement can be made from a horizontal direction to a vertical direction while keeping the tension of the transmission line constant. <P>COPYRIGHT: (C)2013,JPO&INPIT |
