Abstract
Abstract A plurality of upright screw anchors are embedded in the ground to support a lightweight, formed, corrosion-resistant base pad of fiber glass filled polyester resin material and an article such as a transformer, switchgear, air conditioning unit or other load disposed on the top surface of the pad. The lowermost helix carrying ends of the anchors are driven below the frost and seasonal moisture lines of the ground to assure that the anchors provide a stable support for the pad and article. The lowermost edge of the pad may be buried while leaving the top surface thereof exposed to provide an aesthetically pleasing installation and to hinder access to cables and the like in the formed hollow area underneath the pad. Such area may be filled with earth to further impede unauthorized access. The anchors and pad are especially suited for packaging with the article as a unit on a pallet therefor for ease of distribution.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
In combination: a relatively heavy article requiring stable ground-level support free from tilting or heaving such as caused by seasonal changes in environmental conditions; a base pad for said article constructed of corrosion-resistant material having a high strength-to-weight ratio, said pad being provided with a relatively thin, normally horizontally disposed article-supporting panel section; and a plurality of elongated, rigid anchors adapted to be embedded in the ground in horizontally spaced, upright disposition, each of said anchors having a normally uppermost end adapted, upon installation of the anchors, to project above the surface of the ground a sufficient extent to engage and support said pad, thereby supporting said article, said article comprising an electrical transformer for underground electrical distribution lines, said panel section being provided with at least one opening therein for passage therethrough of said distributIon lines into connecting relationship with said transformer, said opening having filler material therein surrounding said lines and filling the area of said opening not occupied by the lines.
Claim 2
Dependent Claim
164 words
In combination: a relatively heavy article requiring stable ground-level support free from tilting or heaving such as caused by seasonal changes in environmental conditions; a base pad for said article constructed of corrosion-resistant material having a high strength-to-weight ratio, said pad being provided with a relatively thin, normally horizontally disposed article-supporting panel section; and a plurality of elongated, rigid anchors adapted to be embedded in the ground in horizontally spaced, upright disposition, each of said anchors having a normally uppermost end adapted, upon installation of the anchors, to project above the surface of the ground a sufficient extent to engage and support said pad, thereby supporting said article, said article comprising an electrical transformer for underground electrical distribution lines, said panel section being provided with at least one opening therein for passage therethrough of said distributIon lines into connecting relationship with said transformer, said opening having filler material therein surrounding said lines and filling the area of said opening not occupied by the lines.
Claim 3
Dependent Claim
41 words
The combination as claimed in claim 1, wherein said transformer has a lower support edge, said panel section having an outer surface conforming closely to the contour of said edge to assure continuous, conforming contact between the latter and said surface.
Claim 4
Dependent Claim
14 words
The combination as claimed in claim 2, wherein said surface is smooth and flat.
Claim 5
Dependent Claim
20 words
The combination as claimed in claim 1, wherein said filler material includes a mixture of epoxy resin and soil particles.
Claim 6
Dependent Claim
40 words
The combination as claimed in claim 1, wherein said panel section is provided with downwardly depending structure defining a hollow area beneath said section within which said uppermost ends of the anchors are disposed and blocking access to said lines.
