ABSTRACT:
A house, building, or the like having an ellipsoid roof and integral, circular sidewall, is produced using a plurality of reinforced forms. Each form has elongate, positively curved, triangular sides defining an apex, and an upwardly inclined, sidewall portion. Fiberglass forms are preferred and they may be tightened together by bolts or interlocked along their edges. Each form at its apex is supported by a centerpost while the sidewall is supported by an outer foundation.
The structure is formed by blowing foam or gas concrete in place onto the reinforced forms, and when the concrete has cured and hardened, the forms are removed and may be reused. The invention eliminates the need for heavy bar or rod reinforcement usually employed for ellipsoid or hemisphere domes and requires only a wire mesh reinforcement.
