た。Further, since the connecting metal fitting 14 for connecting the intermediate support girder and the intermediate support girder is U-shaped and is mounted so as to be slidable around the intermediate support girder, that is, slidably mounted, the intermediate support girder is moved along with the movement of the cable when the cable is extended. It moves along the intermediate support girder and the appearance after installation is poor. Moreover, since the thickness (2 to 3 mm) of the connecting metal fitting 14 projects from the surface of the meson spar or the intermediate support spar, there is a possibility that the cable may be damaged during the wire extension.
