ABSTRACT:
A foundation is provided and includes an upstanding perimeter wall structure enclosing a generally circular plan area of the foundation. The perimeter wall is supported from the foundation and a central upstanding roof support column is also provided and is supported at its lower end from the foundation centrally of the area enclosed by the perimeter wall structure. The column is tubular and a support frame encircles and is supported from the upper end of the column at a level spaced above the upper portions of the perimeter wall structure. The support frame is spaced outwardly of the column and downwardly and outwardly inclined roof rafter members are spaced about the column in generally radial planes with their upper innermost end portions anchored relative to corresponding portions of the frame and their lower outermost end portions anchored relative to corresponding upper marginal portions of the perimeter wall structure. A roof structure is secured over the rafter members and includes a central void area defined by upper marginal portions of the roof structure spaced outwardly from and extending about the upper end portion of the column. A cap structure is supported from the upper marginal portions of the roof structure and the upper end portion of the column forming a weather closure over the upper portion of the roof structure. The foundation supports a heater including a flue opening into the interior of the column and the roof structure includes inner lower panel structures underlying the rafters as well as insulation material disposed between adjacent rafters and overlying the inner panel structure but spaced from the upper marginal portions of the rafters, the spacing between adjacent rafters above the insulation material defining air circulation passages and the cap structure including a ventilation outlet for venting the air circulation passages and seal structure forming an air seal against airflow between the column outer surface and the adjacent inner portions of the roof structure.
