A storage structure comprising a plurality of hollow layers each assembled at ground level and adapted to be lifted to arranged the layers in a vertical stack, each of said plurality of hollow layers comprising a plurality of semi-circular concrete panels arranged in a circle and coupled together by tongue and groove joints, each of said semi-circular concrete panels having a thinner inner section framed by a thicker top section, a thicker bottom section, and two thicker end sections extending vertically between said thicker top section and thicker bottom section, said semi-circular concrete panels locked in a circle by a plurality of straps, each surrounding the circle and each having opposing ends coupled together by a clamp to prevent outwardly directed forces from pushing the semi-circular concrete panels out of the circle and to permit the layers to be lifted to form the vertical stack.
A storage structure comprising:
- a. a plurality of semi-circular wall panels each made of concrete and adapted to be arranged in a plurality of hollow circular layers, and said plurality of hollow circular layers adapted to be arranged in a hollow vertical stack, each of said wall panels having thinner inner section framed by (i) a thicker top portion terminating in a first horizontal planar surface, (ii) a thicker bottom portion terminating in a second horizontal planar surface, (iii) a first thicker end section terminating in a first planar end surface extending between the first and second horizontal planar surfaces, (iv) a second thicker end section terminating in a second planar end surface extending between the first and second horizontal planar surfaces, (v) a tongue extending from one of the first and second horizontal planar surfaces and a groove recessed from the other of said first and second horizontal planar surfaces, and (vi) a tongue extending from one of said first and second planar end surfaces and a groove recessed in the other of said first and second planar end surfaces;
- b. a plurality of hollow circular layers assembled at ground level and adapted to be lifted to form a stack of said plurality of hollow circular layers, each of said plurality of hollow circular layers comprising (i) a set of the plurality of semi-circular wall panels, (ii) first tongue and groove joints between immediately adjacent semi-circular wall panels of the set, said first tongue and groove joints each comprising a tongue extending from a second planer end surface of a semi-circular wall panel and a groove formed in a planer end surface of an immediately adjacent semi-circular wall panel, (iii) a plurality of straps surrounding the set of the plurality of semi-circular wall panels, each of said plurality of straps having a main body portion, a first end portion and a second end portion, and (iv) a plurality of clamps securing the first and second end portions of the straps together and further securing together the plurality of semi-circular wall panels of the set of semi-circular wall panels;
- c. a vertical stack of said hollow circular layers comprising second tongue and groove joints between immediately adjacent hollow circular layers of the stack, said second tongue and groove joints each comprising a tongue extending from a horizontal planar surface of a semi-circular wall panel of a hollow circular layer and a groove recessed in a horizontal planar surfaces of a semi-circular wall panel of an immediately adjacent hollow circular layer of the stack of said plurality of hollow circular layers.
