Abstract: A method and apparatus for producing a downward, wind-induced lift force on a structure including attaching one or more omni-directional mushroom-shaped airfoil assemblies to the top of the structure which create a downward lift force as they are subjected to wind flow.

Abstract: A method and interlocking building system for construction of buildings capable of multiple stories from a variety of standard size panels and a variety of connectors for interlocking the panels. The panels may be horizontally disposed to form floors, ceilings or roofs or may be vertically disposed to form walls. The panels are formed of a plastic shell and contain a plurality of metal strips spaced therein and received within internal guide tracks or integral internal vertically-oriented trussing. The metal strips or trussing have interlocking tooth profiles which project beyond the plastic panel shell. When the panels are used as wall panels, the panels are preferably disposed so that the frame members are vertical. Panels may be interlocked, one vertically above the other, to form multiple stories, with the frame members of all stacked wall panels being in horizontal alignment to form generally continuous vertical strength members.

Abstract: A method and system for construction of building structures from a variety of standard size panels having integral dovetail tenons on all four edges and a variety of connectors with corresponding mortises for interlocking the panels. The panels may be horizontally disposed to form floors, ceilings or roofs or may be vertically disposed to form walls. The panels are produced from blow-molded plastic. Panels are interlocked in columns and rows of a planar array to form walls, floors, roofs, etc. Panels can also be interlocked edge to edge in a non-planar orthogonal manner, allowing the panels to be interconnected in virtually unlimited ways. Plastic frame members with trussing interconnect to the panels to provide rigidity and strength to the assembled building structure. The panels may be formed of opaque material for ordinary sheds or of transparent or translucent material for greenhouses.

Abstract: In a building system, extruded plastic panel components are joined together to form a building structure. External and internal connectors adhesively join the panel components together to form a completed structure. The panel components are internally ribbed and may be partially or fully insulated. Internal conduits in the panel components provide passageways for electrical wiring, plumbing and other required utilities.
