' 3 Claims. (31. 18934) porcelain enamel structural panel that is particularly adapted to withstand exposure to moisture and actual immersion in water without structural failure or separation of the components thereof.
Another object of the invention is to provide an improved porcelain enamel structural panel that is light'in weight, pleasing in appearance, economical to manufacture and assemble, durable, weather-resistant and adapted to withstand thermal and vibration stresses.
Still another object of the invention is to provide an improved porcelain enamel structural panel that may be installed on a building with a minimum of labor and expense. v
Yet another object of the invention is to provide an improved porcelain enamel structural panel incorporating an improved fastening device that functions to interconnect adjacent panels and also functions to stabilize the skins of the panel in the event the core thereof is destroyed.
The above as well as other objects and advantages of the invention will become apparent from the following description, taken in conjunction with the accompanying drawing wherein:
Figure 1 is a perspective view of a porcelain enamel structural panel constructed in accordance with the present invention;
Fig. 2 is an enlarged cross sectional view of the structure illustrated in Fig. 1, taken on the line 22 thereof and showing the same installed adjacent a similarly constructed panel;
Fig. 3 is a cross sectional view of a portion of the structure illustrated in Fig. 2, taken on the line 33 thereof; and
Fig. 4 is a greatly enlarged cross sectional view of a portion of the structure illustrated in Fig. 2, taken on the line 44 thereof.
Referring to the drawing, a structural panel, generally designated 10, is illustrated which may be considered to be a structural panel for use on an exterior wall of a building, although it will be understood that the present invention is applicable to other uses. In the preferred construction illustrated, the panel 10 is shown as being shaped generally in the form of a rectangular block but it will be understood that the size and shape of the panel may be altered to fit the wishes of the designer.
The panel 10 is comprised of a honeycomb core 12 which may be made from phenolic impregnated kraft paper or other suitable material in any desired or conventional manner. The honeycomb core 12 is formed generally in the shape of a parallelepiped and defines a plurality of laterally extending passageways 14 which are 2,911,076 Patented Nov. 3, 195.9
open at each end. In the preferred embodiment illustrated, the passageways 14 are filled with an expanded silicate 15, such as perlite, or other heat-insulating material, for the purpose of increasing the heat-insulating properties of the panel.
A pair of spaced, oppositely directed plates or skins 16 and 18 are disposed on opposite sides of the core 12'. The corner portions of each of the skins are removed and the marginal portions of the skins are bent so as to-form inwardly projecting flanges, such as 20 and 22, the adjacent laterally extending edge portions of which are disposed in abutting relationship. The skins 16 and 18 are identical in construction and, as best seen in Fig.4, each of the skins 16 and 18 includes a relatively thin metal base 24 which may be made of sheet steel or other suitable material. The inner and outer surfaces of base 24 are coated with layers 26 and 28, respectively, of glass-like porcelain enamel, the porcelain enamel being fused to the base so as to be permanently secured thereto. The particular porcelain enamel coating that is applied to the inner andouter surfaces of the base is not critical for the purposes of the present invention and any of a variety of porcelain frits well known to persons skilled in the art may be fused to the base so as to provide the glass- like layers 26 and 28 of porcelain enamel. Such porcelain enamel coatings are pleas.- ing in appearance, weather-resistant, strong, durable and wall adapted to withstand thermal and vibration stresses.
According to the present invention, the surface 30 of the porcelain enamel layer 26 on the inner side of the base 24 is coated with a layer 32 of a metallic oxide, such as aluminum oxide, the metallic oxide coating being fused to the surface 30 of the porcelain enamel layer 26 so as to be permanently secured thereto.
For the purpose of fixing the skins 16 and 18 to the core 12, a water insoluble, high strength, organic adhesive 33 is applied to the metallic oxide coated inner surface of each of the skins 16 and 18. Adhesives suitable for this purpose include epoxy resins, such as polymers of epichlorohydrin, available commercially under the designations Araldite and Epon from the Ciba Company and Shell Chemical Company, respectively.
The epoxy resins are available in the form of liquids and may be applied to the metallic oxide coated surfaces of the skins by brushing, spraying, or in any other suitable manner. The epoxy resins form a high strength, water insoluble adhesive which adheres to the metallic oxide coated surfaces of the skins 16 and 18 and the phenolic impregnated kraft paper core 12 so as to securely bond the skins to the core. Such a constructtion enables the panel to withstand exposure to moisture that may be present in the ambient atmosphere as well as actual immersion in water without structural failure and without separation of the components of the panel.
In order that a plurality of panels may be easily and quickly joined so as to form an exterior wall, a plurality of tie members, generally designated 34 are provided. The tie members 34 are preferably of the cross sectional contour illustrated in Fig. 2 and include a web portion 36 having a pair of integral spaced flanges 38 and 40 projecting outwardly therefrom so as to define a channel 42 while a pair of integral co-planar leg portions 44 and 46 project laterally outward from the outer ends of the flanges 38 and 40, respectively. The web 36 and the flanges 38 and 40 extend into a similarly shaped recessed portion 48 provided in the core 12 while the outer surfaces of each of the legs 44 and 46 abut the inner sur faces of the adjacent inwardly projecting flange of the skins and are secured thereto by screws 50. When the panels are installed in adjacent relationship on the wall of a building, the channels 42 are disposed in confronta ing relationship and an elongated, rectangularly cross sectioned bar 52, which is of such size as to snugly fit the channels 42 in the mating tie members 34, may be inserted in the channels 42 of the adjacent tie members so as to preventrelative lateral movement between adjacent panels. A conventional calking or sealing compound 53 may be interposed between the .panels so as to seal the joints between the panels.
In the event the panel is one of the uppermost panels .in the Wall, the upper flanges 22 of the skins 16 and 18 may be secured together by means of a relatively thin metal strap .54, the end portions of which are secured to the flanges 22 of the skins 16 and 18 by screws 56.
The tie members 34 and the straps 5 4 also function to maintain or stabilize the skins 16 and 18 in spaced rela- .tionship so as to prevent structural failure of the panel in the event the core 12 is destroyed by fire or otherwise damaged after the panel has been installed on the wall of a building.
While a preferred-embodiment of the invention has been shown and described, it will be understood that various changes and modifications may be'made without departing from the spirit of the invention.
What is claimed is:
1. In a laminated structural panel, the combination comprising a core, a metal skin having a layer of percelain enamel-fused to the surfaces thereof, one surface .of the porcelain enamel layer on one side of the skin having a layer of aluminum oxide fused thereto, a layer of Water insoluble organic adhesive, said layer of water insoluble organic adhesive adhering to said layer of aluminum oxide and to said core whereby said layer of aluminum oxide is bonded to said core by said Water insoluble :organic adhesive.

3. In a laminated structural panel, the combination comprising a core,.a pairof skins, one of said skins being secured to each side of said core, each of said skins including a metal base having a layer of porcelain enamel on each side thereof, an aluminum oxide coating fused to the surface of the porcelain enamel on one side of each of said skins, a layer of water insoluble organic adhesive intermediate each of said aluminum oxide coated surfaces and said core, each of said layers of water insoluble organic adhesive adhering to the adjacent coating of aluminum oxide and to the core whereby said aluminum. oxide coated surfaces are bonded to said core by said water insoluble organic adhesive.
