摘要

PURPOSE:To improve the work efficiency by placing a base member in a prescribed position on an iron tower and moving an attaching member to an attaching position by a moving means and attaching an iron tower member and said base member in one direction. CONSTITUTION:A washer 6' is fitted under an iron tower member 52-1 by a special bolt 6 inserted to an attaching hole 8 of the iron tower member 52-1 and an attaching hole 7 of a base member 53 by the moving means, and nuts 5 and 5 are set to the bolt 6 on the base member 53 through a washer 5'. The bolt 6 and nuts 5 and 5 are clamped to attach the base member 53 to the iron tower member 52-1 from above a platform 52 in one direction by the attaching member like the special bolt 6. Thus, an antenna unit is attached to a high position of the iron tower only in one direction of the platform floor surface, and it is unnecessary to support a worker in a space under type platform and to stretch a human body safety net, and the work efficiency is improved.
