Abstract
Abstract A composite building panel and method of its construction wherein a preferably rectangular sheet is nailed to wooden strips extending around the sheet perimeter to define a form. A layer of portland cement and sand mortar is spread uniformly over the sheet within the form. A plurality of insulation blocks are applied directly to the wet mortar with uniform spacing between the respective blocks and between the blocks and the wooden strips. Mortar is then spread over the blocks, filling the voids left by such spacing and establishing a covering layer over the blocks. A second sheet is then nailed to the blocks and fasteners extend through the sheets and into the wet mortar grid throughout the panel. Upon hardening the panels are installed by the removal of one or more of the wooden strips so that the projecting margins of the sheets may be lapped with other construction elements to create a secure joint. Wooden blocks may be used with the peripheral strips to provide appropriate voids upon removal of the strips for accommodating electrical junction boxes as well as conduits. Pursuant to an alternate embodiment, fluid tight, hollow containers are substituted for the insulation blocks to provide cavities in the panels for solar energy collection by the flow of a liquid through the interconnected container system.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
165 words
A prefabricated building panel comprising: a pair of generally parallel, spaced apart sheet members comprising the major surfaces of said panel; a segmented strip interposed between said members and extending around the periphery of the panel; releasable means securing said panels to the strip segments; a plurality of slab shaped spacers interposed in mutually spaced apart disposition between the members and arranged in a plurality of transversely and longitudinally extending rows to define between said rows of spacers a grid of longitudinally and transversely extending voids across the panel, the spacers being spaced inwardly from the inner surfaces of said members and the strip segments respectfully; and an initially flowable, hardened, rigid material surrounding each spacer and completely filling the void between said members and between the respective adjacent spacers, said material being bonded to the inner surfaces of the members and defining a continuous grid of said rigid material throughout the panel binding the panel together and preserving the positional integrity of the spacers.
Claim 2
Dependent Claim
165 words
A prefabricated building panel comprising: a pair of generally parallel, spaced apart sheet members comprising the major surfaces of said panel; a segmented strip interposed between said members and extending around the periphery of the panel; releasable means securing said panels to the strip segments; a plurality of slab shaped spacers interposed in mutually spaced apart disposition between the members and arranged in a plurality of transversely and longitudinally extending rows to define between said rows of spacers a grid of longitudinally and transversely extending voids across the panel, the spacers being spaced inwardly from the inner surfaces of said members and the strip segments respectfully; and an initially flowable, hardened, rigid material surrounding each spacer and completely filling the void between said members and between the respective adjacent spacers, said material being bonded to the inner surfaces of the members and defining a continuous grid of said rigid material throughout the panel binding the panel together and preserving the positional integrity of the spacers.
Claim 3
Dependent Claim
21 words
The panel of claim 1, wherein said spacers are comprised of thermal insulation material, thereby enhancing the insulation of the panel.
Claim 4
Dependent Claim
12 words
The panel of claim 2, wherein said insulation material is polyurethane foam.
Claim 5
Dependent Claim
24 words
The panel of claim 1, wherein said initially flowable hardened material is the product resulting from a mixture of sand, portland cement and water.
Claim 6
Dependent Claim
37 words
The panel of claim 1, wherein said sheet members are substantially rectangular sheets of metal, and wherein said strip includes a separate segment for each of the four sides of the panel defined by said rectangular members.
Claim 7
Dependent Claim
79 words
The panel of claim 5, wherein said segments are wooden, and wherein said releasable means includes a plurality of fasteners engaging the wooden segments and said members respectively, said fasteners being selectively removable to permit the removal of any of said segments as may be desired to create a channel between the spaced apart members at an edge of the panel to accommodate integration of other building components with the panel by installation of a component in said channel.
Claim 8
Dependent Claim
52 words
The panel of claim 1, wherein said spacers comprise hollow containers capable of holding fluid and wherein is provided conduit means placing the containers in mutual communication and communicating exteriorally of the panel, whereby fluid may be flowed through the panel to permit the latter to be used in solar heating applications.
Claim 9
Dependent Claim
33 words
The panel of claim 1, wherein at least one of said sheet members is provided with a black exterior surface to enhance the collection of solar energy for heating fluid in said containers.
Claim 10
Independent Claim
138 words
A method of constructing a prefabricated building panel comprising: creating a form for a plastic, hardenable material by securing an upwardly extending strip to the peripheral marginal edge of a substantially flat, sheet member; spreading a layer of said plastic material over the surface of said member within the perimeter bounded by said strip; placing a plurality of spacers on said layer of plastic material in mutually spaced apart disposition and spaced inwardly from said strip; spreading a second layer of said plastic material over the spacers to cover the latter and to fill the space between the spacers and between the spacers and the strip; installing a second, substantially flat member over said second layer of material and in intimate contact therewith; and permitting said material to harden to preserve the positional relationship between the panel components.
Claim 11
Independent Claim
138 words
A method of constructing a prefabricated building panel comprising: creating a form for a plastic, hardenable material by securing an upwardly extending strip to the peripheral marginal edge of a substantially flat, sheet member; spreading a layer of said plastic material over the surface of said member within the perimeter bounded by said strip; placing a plurality of spacers on said layer of plastic material in mutually spaced apart disposition and spaced inwardly from said strip; spreading a second layer of said plastic material over the spacers to cover the latter and to fill the space between the spacers and between the spacers and the strip; installing a second, substantially flat member over said second layer of material and in intimate contact therewith; and permitting said material to harden to preserve the positional relationship between the panel components.
Claim 12
Dependent Claim
57 words
The method of claim 9, wherein said panel is polagonal, and wherein is included the step of removing said strip along one edge of the panel to provide a channel between the projecting sheet members, whereby said channel may be used to receive an edge of a second panel therein to facilitate the fastening of adjacent panels.
Claim 13
Dependent Claim
17 words
The method of claim 10, wherein is included the step of installing electrical components in said channel.
