International ClassE04C 003/34AbstractA post and/or pole segment formed by filling a form with a composite mixture of a bonding agent and a filler material. The composite mixture is placed in a form in a fluid state and allowed to solidify. The form is retained as an integral member of the post and/or pole segment. The post and/or pole segments are arranged to be connected in an end to end arrangement to form a post or pole of extended length. The form and the composite mixture of the post and/or pole segment are of recycled material.Field of SearchEnd-to-end connected sectionsUpright Utility pole Supporting shaft Column, mast, etc., construction Using prefabricated unit Having shell-like outer layer Open-ended, self-supporting conduit, cylinder, or tube-type article Multilayer (continuous layer) Single layer (continuous layer) Polymer or resin containing (i.e., natural or synthetic) Randomly noninterengaged or randomly contacting fibers, filaments, particles, or flakes Natural or synthetic rubber or rubber-like compound containing Glass, ceramic, or sintered, fused, fired, or calcined metal oxide or metal carbide containing (e.g., porcelain, brick, cement, etc.) Edge feature Including fastener for attaching to external surface Concentric preforms | |
