Building structure

Claim 2

An improved building structure comprising a horizontal floor, a plurality of vertical planar wall members arranged to define a hexagon and projecting upwardly from said floor, means for rigidly connecting said wall members to form a hexagonal outer frame, a hexagonal inner frame positioned concentrically within said outer frame and defining a center opening, a set of angularly arranged curved beams for each side of said outer frame and projecting generally radially outwardly from said inner frame over said outer frame with cantilevered outer eNd portions projecting outwardly from said outer frame, a set of complementary trapezoidal insulated roof panels mounted on said beams for each side of said outer frame and extending from said inner frame outwardly over said outer frame in adjacent relation, each said roof panel having a substantially spherical curvature conforming substantially to the curvature of said beams, the radius of curvature of said beams and said roof panels being greater than the distance between opposite wall members of said outer-frame, each set of roof panels having outer edge surfaces curving uniformly within a vertical plane extending substantially parallel to the corresponding side of said outer frame, means for connecting adjacent edges of said roof panels to the corresponding said beams, means forming a liquid-tight seal between adjacent edges of said roof panels, and means forming a transparent skylight cover for said center opening.

Claim 3

A building structure as defined in claim 1 wherein said outer and inner frames have corresponding parallel sides, and one set of said beams extends from each side of said inner frame over the corresponding side of said outer frame.

Claim 4

An improved building structure comprising a horizontal floor, a plurality of vertical planar wall members arranged to define a polygon and projecting upwardly from said floor, means for rigidly connecting said wall members to form a polygonally-shaped outer frame, an annular inner frame positioned concentrically within said outer frame and defining a center opening, a set of angularly arranged curved beams for each side of said outer frame and projecting generally radially outwardly from said inner frame over said outer frame with cantilevered outer end portions projecting outwardly from said outer frame, a set of complementary trapezoidal insulated roof panels mounted on said beams for each side of said outer frame and extending from said inner frame outwardly over said outer frame in adjacent relation, each said roof panel having a substantially spherical curvature conforming substantially to the curvature of said beams, each set of roof panels having outer edge surfaces curving uniformly within a vertical plane extending substantially parallel to the corresponding side of said outer frame, each of said roof panels being substantially trapezoid in configuration and includes an upper sheet and a lower sheet of plastics material, a core of insulation material between said upper and lower sheets, said upper sheet of each panel projects outwardly from the sides of the corresponding said core to form projecting flanges, said flanges of adjacent said panels are arranged in overlapping relation over the adjacent said beam, means for connecting adjacent edges of said roof panels to the corresponding adjacent said beams, and means forming a liquid-tight seal between adjacent edges of said roof panels.

Claim 5

An improved building structure comprising a horizontal floor, a plurality of vertical planar wall members arranged to define a polygon and projecting upwardly from said floor, means for rigidly connecting said wall members to form a polygonally-shaped outer frame, an annular inner frame positioned concentrically within said outer frame and defining a center opening, a set of angularly arranged curved beams for each side of said outer frame and projecting generally radially outwardly from said inner frame over said outer frame with cantilevered outer end portions projecting outwardly from said outer frame, a set of complementary trapezoidal insulated roof panels mounted on said beams for each side of said outer frame and extending from said inner frame outwardly over said outer frame in adjacent relation, each said roof panel having a substantially spherical curvature conforming substantially to the curvature of said beams, each set of roof panels having outer edge surfaces curving uniformly within a vertical plane extending substantially parallel to the corresponding side of said outer frame, each of said roof panels being substantially trapezoid in configuration and includes an upper sheet and a lower sheet of plastics material, a core of insulation material between said upper and lower sheets, said upper sheet of each panel projects outwardly from the sides of the corresponding said core to form projecting flanges, said flanges of adjacent said panels are arranged in overlapping relation over the adjacent said beam, means for connecting adjacent edges of said roof panels to the corresponding adjacent said beams, and means forming a liquid-tight seal between adjacent edges of said roof panels.

Claim 6

A building structure as defined in claim 3 including a curved gutter member extending adjacent said outer edge surfaces of each set of said roof panels for collecting water draining from said roof panels.

Claim 7

A building structure as defined in claim 3 wherein a set of three of said roof panels extend across each side of said outer frame.

Claim 8

A roof structure as defined in claim 3 wherein the radius of curvature of said beams and said roof panels is greater than the distance across said outer frame.

Claim 9

A building structure as defined in claim 3 including polygonally-shaped transparent panel means for covering said center opening and forming a skylight therefor.

Claim 10

A building structure as defined in claim 3 wherein the upper sheet of each said roof panel includes an integral lip projecting downwardly from the outer end of each said panel.
