Abstract
A substantially spherical shaped structure constructed of reinforced concrete poured in a plurality of courses, each course consisting of a horizontal substantially annular band extending completely around the structure. A series of forms are shaped and positioned so as to create two adjacent concentric annular arcuate surfaces, thus forming an inner and an outer wall between which a suitable structural material, such as concrete, in a fluid state may be poured and allowed to harden. Additional forms, substantially vertically above and arcuately continuous with the previous surfaces, are fastened to the first series of forms and again a suitable structural material is poured between the forms and allowed to harden above the previously hardened band. This procedure is repeated until the desired spherically shaped structure has been obtained. Because of the symmetrical nature of a spherical structure, the same forms used for the lower portion of the structure may also be reversed and used in constructing the upper portion.
