发明名称 LIGHTWEIGHT PRESTRESSED TOWER
摘要 A lightweight, prestressed tower includes 1) a base load transfer assembly to be mounted on a support base fixture assembly which is mounted on a base support pad; 2) a primary truss assembly consisting of a plurality of truss bays interconnected by diagonal and vertical tension members between horizontal frame assemblies; 3) a central compression tube assembly operable to be extended centrally of the truss bays from bottom to top having tubular sections connectable to each other to provide a central compression load assembly; and 4) an upper load transfer assembly connected to an upper end of the central compression tube assembly and by horizontal and diagonal tension members of the primary truss assembly. The primary truss assembly with the diagonal and vertical tension members and frame compression tubes is operable to have predetermined tension forces applied thereto through extension of the central compression tube assembly to create desirable load support characteristics. The upper load transfer assembly is operable to receive and support an antenna or other such equipment required to be elevated above a ground support surface for proper operation thereof.
