DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(13) As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure.

(14) Reference is now made to the drawings, wherein like characteristics and features of the present invention shown in the various FIGURES are designated by the same reference numerals.

First Preferred Embodiment

(15) Referring to attached FIGS. 1-11, building panel system 10 is disclosed which provides heat insulation and defines a continuous internal flow path, referred to herein as the system passageway 12, through which a gaseous fire retardant can be delivered to extinguish or contain a fire. The system 10 includes panels 20 of any desired shape to form external or internal building structures such as building walls and partitions insulating wall portions abutting a structural wall, including foundations and walls 20 of ducts 130, and panel splicing connectors 40 for joining each panel 20 end to end to the next.

(16) Each panel 20 is formed of a first panel sheet 22 and a second panel sheet 24 parallel to and spaced apart from the first panel sheet 22, and a sheet interconnecting structure 30 extending between and structurally joining together the first and second panel sheets 22 and 24. The panel splicing structures 40 are perforated to be capable of passing the gaseous fire retardant from the interior of one panel 20 to the next panel 20, so that the all parts of system 10 are in fluid communication with each other. A panel peripheral strip 28 optionally is provided along the upper and lower ends or edges of the system panels 20 to contain gas flowing through the system passageway 12. The panel sheets 22 and 24 and the panel splicing structures 40 may be formed of any suitable durable material, but preferably are formed of ABS plastic.

(17) Gas release structures, such as ports or nozzles, are provided along the panels 20 were desired and are in fluid communication with the system passageway 12 at selected locations. The internal gap G between the first and second panel sheets 22 and 24 provides a layer of air within each panel 20 which is a highly effective heat insulator. The system passageway 12, defined by the system-wide fluid communication through the interconnected panel internal gaps G, permits a selected gas such as carbon dioxide to be delivered, such as from gas cylinders GC, into at least one entry coupler EC to flow throughout the system 10, build gas pressure, and be discharged through the gas release structures over a target area T. A series of nozzles, for example, may direct the gas from a system passageway 12 within the foundation F at a high flow rate along and against the outside surface of a building wall W to prevent the wall W from catching fire and to extinguish any fire which has begun.

(18) As noted, the panel system 10 may form a duct 130 such as for an air conditioning system. In this instance, the first panel sheet 22 defines a duct interior tube 132, as shown in FIG. 1, and the second panel sheet 24 defines a duct exterior tube 134 containing and coaxial with the interior tube 132 and sized relative to the interior tube 134 to be spaced radially apart from the duct interior tube 132, thereby defining an annular panel internal gap G. The interior and exterior duct tubes 132 and 134 may be of round, square or any other desired cross-sectional shape. The sheet interconnecting structure 30 preferably includes a series of radial fins 32 extending between and joined to the first and second panels 20 and extending parallel to the common axis of the tubes 132 and 134 so that the fins 32 do not obstruct axial gas flow through the gap G between the tubes 132 and 134. The panel splicing structures 40 each preferably take the form of a connecting ring 40 having an outer tube segment 42 sized to slide snugly over the duct exterior tube 134 outward surface, and an inner tube segment 44 sized to slide snugly over the duct interior tube 132 inward surface, and a perforated tube segment connecting flange 46 extending between and connecting the inner and outer tube segments 42 and 44 spaced inwardly from the opposing ends of the tube segments 42 and 44. Perforations in the tube segment connecting flange 46 preferably are a circumferential series of relatively large holes 46A in the flange 46. As a result of this construction, the opposing ends of adjacent duct 30 segments fit snugly into the opposing sides of the connecting ring 40 to sealingly interconnect the duct 130 130 segments, and a glue or adhesive is optionally provided on the surfaces where the connecting ring 40 overlaps and abuts the given duct segment interior and exterior tubes 132 and 134. The use of an adhesive enhances both sealing and structural strength of the duct 130 as a whole. When assembled, the central space CS within the series of duct interior tubes 132 of the resulting duct 130 forms an air conditioning system flow path, while the annular space AS between the collective interior and exterior tubes 132 and 134, also referred to as gaps G, define part or all of the present system passageway 12.

(19) A duct transition joint 140 is optionally provided for connecting an end of a square duct 130A to an end of a round duct 130B. See FIG. 4. The duct transition joint 140 includes the joint exterior and interior tubes 144 and 142 respectively as described, except that their cross-sectional shapes progressively changes from round to square, so that the transition joint 140 has a joint square end 140A and a joint round end 140B. The sheet interconnecting structure 36 includes a radial connecting flange 36, similar to connecting flange 46 of the connecting ring 40, set inwardly from either end of the transition joint 140 and having gas passing holes 46A, and the exterior tube 144 preferably is sized to fit snugly over the outward surface of the exterior tube 134 of the adjacent round or square duct 130 segment, and the interior tube 142 preferably is sized to fit snugly along the inward surface of the interior tube 132. And, once again, an adhesive may be used for enhanced sealing and structural strength for the duct 130 as a whole. A take off boot 146 is provided, the flange of which fits snugly inside the inward surface of the interior tube 132.

(20) Other building structures such as walls and partitions normally require system panels 20 that are planar. A preferred interconnecting structure 30 for such panels 20, as shown in FIG. 3, has connecting legs 36 protruding outwardly from one panel sheet 22 and meeting and being connected to the other panel sheet 24, so that gas can flow through lateral spaces between connecting legs 34. The legs 34 preferably protrude from a grid 38 of crossing and interconnected grid flanges 38A, such as of the illustrated egg crate design, to add structural strength to the panel 20. FIG. 8 shows smaller round cross-section take off duct 130 segments branching from a square cross-section main duct 130.

(21) One building structure typically requiring planar system panels 20 is a foundation insulation wall portion abutting a structural wall portion. The series of panels 20 is affixed along the outer surface of the foundation structural wall portion, below ground level, and gas release structures in the form of nozzles 26 protrude upwardly from the upper edges of the series of system panels 20. Fire retardant, again preferably in the form of carbon dioxide gas, is delivered into the system passageway 12 such as from a gas cylinder GC as illustrated, although other dry chemicals may be used for this purpose. The nozzles 26 preferably direct the gas upwardly close to and generally parallel to the outer face of the above ground building wall W. See FIG. 6. The panel splicing structures 40 for planar system panels 20 preferably are plastic I-beams having opposing and spaced apart gripping flanges 42 and 44 to slide snugly over outward surfaces of panel sheets 22 and 24, respectively, and a connecting flange 46 with a series of gaseous substance passing holes 46A.

(22) The plastic sheets 22 and 24 forming the system panels also function as a barrier to the entry of insects by providing a plastic encased building B, such as the home illustrated in FIG. 7.

(23) Panels 20 also may be used to construct wall portions of a variety of alternative products, as illustrated in the FIGURES attached and identified collectively as Alternative Products. These products include but are not limited to storage sheds, shower stalls, heat insulated boxes such as for preserving food and coffins, as illustrated.

(24) While the invention has been described, disclosed, illustrated and shown in various terms or certain embodiments or modifications which it has assumed in practice, the scope of the invention is not intended to be, nor should it be deemed to be, limited thereby and such other modifications or embodiments as may be suggested by the teachings herein are particularly reserved especially as they fall within the breadth and scope of the claims here appended.
