Abstract
A foundation structure for supporting a high rising light pole in which a plurality of vertically extending reinforcing rod assemblies are arranged in a circle with the tops bolted to a base plate on the bottom of the pole and extending downwardly into a vertical earth bore of relatively small diameter, each rod assembly comprising a bottom section of conventional carbon steel which is connected by a threaded coupling to a top section of high tensile strength heat treated steel, the assembly being set in the bore hole which is then filled with concrete.
Claims6
A reinforced foundation structure in the form of a concrete column adapted as a support for a relatively high standing light pole or the like, said foundation structure comprising one or more reinforcing rod assemblies embedded in concrete which forms the main body of the columnar structure, said rod assembly comprising a lowermost section of steel reinforcing rod material and constituting a substantial portion of the length of the rod assembly and an uppermost section of a rod material which has a tensile strength and resistance to shear stress substantially greater than the material of the lowermost rod section, said rod sections being joined by a coupling member which connects the rod sections in axial alignment.
