UNDER BRACING APPARATUS OF STEEL POLE FOR TELECOMMUNICATION

摘要

PURPOSE: An under bracing apparatus of a steel pole for communication is provided to prevent the collapse of the steel pole by controlling the number of unit bracing blocks according to an installation condition. CONSTITUTION: A first slot(11) and a second slot(12) are formed in a steel pipe(10). The first slot is orthogonal to the second slot. A fixed shaft(21) passes through the first slot and the second slot. A combination hole is formed in a unit bracing block(30). A washer(22) and a fixing nut(23) prevent the separation of the unit bracing blocks. A fixed wire is connected to a stay rod underground.
