发明名称 PULTRUDED UTILITY LINE SUPPORT STRUCTURE AND METHOD
摘要 A utility line support structure (10) for use as a tangent crossarm or deadend including a hollow pultruded beam (20) with a bushing (30) inserted into a transverse hole (22) in the beam. Bushing (30) includes a hollow inner member (32) for receiving a bolt (60) and a pair of integral washers (34) arranged on opposite ends of inner member (32) and against an outer surface of the beam (20). The hollow inner member (32) and the integral washers (34) cooperate to support axial loads applied by the bolt (60). End caps (50) extend over opposite ends of the beam so as to prevent moisture from entering the beam. Also, a method for adapting a non-standard sized utility line support beam to be compatible with standard-sized tooling.
