Abstract

Abstract Prefabricated insulated wall panels formed from overlying layers of heat resistant materials. The panels are capable of being assembled in abutting relation on the outer surface of a metallic enclosure. The panels have an inner fibrous insulation layer of materials such as asbestos, glass fiber, mineral wool, aluminum silicate fibers or felt secured together with inorganic binders such as bentonite, portland cement or high temperature calcium aluminate cements or an organic binder such as phenolic or latex. The insulation layer has a compressive strength sufficient to afford a suitable working surface. A heat-resistant thermosetting layer formed from an organic adhesive with a base of neoprene, rubber, silicone, or resin adhesive is applied to the insulation layer and bonds a reinforced resin laminate layer formed from polyester, phenolic, or epoxy resin, with glass fiber or fibrous asbestos. The panel joints have bonding strips of several types and configurations securing the resin laminate layer.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 32 words
Prefabricated panels according to claim 1, in which jointures are formed between said panels which are in abutting relation, and means disposed along said jointures for continuously connecting said insulated wall construction.
Claim 2
Dependent Claim 39 words
Prefabricated panels according to claim 1, in which said thermosetting resin layer is reinforced by the fibers of said fibrous insulation layer and said thermosetting resin layer is coextensively positioned on the exposed side of said fibrous insulation layer.
Claim 3
Dependent Claim 65 words
Prefabricated panels according to claim 1, in which said thermosetting resin layer is reinforced by the fibers of the fibrous insulation layer, said thermosetting resin layer covering the exposed side of said fibrous insulation layer and said reinforced resin laminate layer applied over said thermosetting resin layer thereby forming said laminate panels with a resiliency selected to compensate for thermal expansion of said metallic enclosure.
Claim 4
Dependent Claim 29 words
Prefabricated panels according to claim 1, in which said fibrous insulation layer, said thermosetting resin layer and said resin laminate layer are formed into a concentric cylindrical wall configuration.
Claim 5
Dependent Claim 63 words
Prefabricated panels according to claim 1, in which said thermosetting resin layer and said resin laminate layer are formed from a polyester resin and said fibrous insulation layer is formed from a material of the class consisting of fibers of asbestos, glass, mineral wool, and aluminum silicate, together with a binder of the class consisting of calcium aluminate, Portland cement, phenolic and latex.
Claim 6
Dependent Claim 47 words
Prefabricated panels according to claim 1, in which said panels are secured on the outer surfaces of said metallic enclosure with said fibrous insulation layer, thermosetting resin layer, and resin laminate layer of each of said panels, positioned in juxtaposed relation to form jointures between said panels.
Claim 7
Dependent Claim 22 words
Prefabricated panels according to claim 7 in which bonding means extend along the length of said jointures for joining said panels together.
Claim 8
Dependent Claim 42 words
Prefabricated panels according to claim 8, in which said bonding means are formed from strips secured to said panels at said jointures and said strips fabricated from material having physical properties similar to the physical properties of said reinforced resin laminate layer.
Claim 9
Dependent Claim 17 words
Prefabricated panels according to claim 9, in which said strips are formed with a uniform cross section.
