Patent ID: 8333045

Claim:
An architectural structure having a longitudinal axis comprising (a) first and second cement or concrete sections having a first end and a second end, each of said sections having (i) an upper surface parallel to said longitudinal axis; (ii) a lower surface parallel to said upper surface and to said longitudinal axis; (iii) an outer wall surface extending from the first end to the second end, the outer wall surface extending between and at substantially right angles to said upper surface and said lower surface, and (iv) an inner wall surface extending from the first end to the second end, the inner wall surface extending upwardly from said lower surface at an acute angle to said lower surface; (b) one or more reinforcing bars, each having a first end embedded in said first section and a second end embedded in said second section, said one or more reinforcing bars being positioned to lift said architectural structure; (c) one or more hollow tubes, each having a first end embedded in said first section and a second end embedded in said second section, the hollow tubes being filled with the same cement or concrete used to form the first and second cement or concrete sections and the cement or concrete filling the one or more hollow tubes being integral with the cement or concrete of the first and second cement or concrete sections; and (d) first and second insulation members, said first insulation member being in interfacial engagement with the inner wall surface of said first section and said second insulation member being in interfacial engagement with the inner wall surface of said second section, said reinforcing bars and said hollow tubes extending through said first and second insulation members.
