A structural element (10) for forming a panel, with an upper plane (12) and lower plane (14) which are parallel and deformed along their plane at intervals by pods (16) which extrude toward the opposing plane with their internal faces mating to one another.

Hard panels formed from a wood-based material and having a decorative layer for floor coverings are provided, at least on two opposite edges, with coupling devices made in one piece with the panels wherein similar panels may be coupled together to form a floor covering, wherein these coupling devices provide for an interlocking in a direction perpendicular to the plane of coupled panels, as well as in a direction perpendicular to the edges concerned and parallel to the plane of coupled panels. These coupling devices are constituted of a tongue and a groove. The top side of the tongue has a protrusion that cooperates with a meshing recess located in the lower side of the upper lip of the groove of the coupling devices, and a portion extending generally parallel with the plane of the panel to form a contact surface cooperating with the lower side of the upper lip of the groove.

The present invention is to provide assemblies with polygon shaped panel frames, separators and parts for light weight construction that is versatile, rigid, flexible and structurally stable. The assemblies with polygon shaped panel frames, separators and parts for constructing a complete building structure eliminates the need for conventional framing using unitized polygon shaped panel frames with alignment pieces, separators and fastener parts connected together. The assemblies with polygon shaped panel frames, separators and parts comprises of panel frames which are different geometric shapes or polygon parts, including but not limited to circles, ovals, triangles, trapezoids, rectangles, squares, pentagons, hexagons, etc. Panel frames can be hollowed or solid and can be fabricated as pieces of and in itself. Panel frames can be composed of many types of materials including but not limited to wood, metal, polymers, composites, plastics, etc. Two (2) or more panel frames are connected with fasteners utilizing a link. Links are parts that create separation between the panel frames and also conjoin other panel frames. Links provide load transfer and can be made of polymers, wood, composites, metal, plastics, etc. The panel frames and links are connected together using fasteners like screws, bolts, nuts, tee-nuts, rivets, rivet nuts, couplers, standoffs, dowels, etc. The panel frames and links are designed to repeat and can provide a building structure with window and doorway openings space and utility space for electrical and plumbing installations. Further, the assemblies can be easily rearranged and reassembled to achieve the desired configuration at low cost, efficient time and minimal labor.

A temperature controlled structure assembly comprises an array of structural panels each including at least one channel formed therein. At least one channel of each of the structural panels is aligned with at least one of the channels of an adjacent one of the structural panels to form a continuous channel extending through the array of the structural panels. At least one functional panel overlays the array of structural panels and is exposed for contact with a user. At least one heat exchanging element is disposed within the continuous channel and configured to exchange heat with the at least one functional panel in order to heat or cool the at least one functional panel.
