Abstract
Abstract An improved panel and method of making the panel for building construction in which fiberglass layers separated by insulation and having plastic reinforcing spaced intermediate the extent of the same provides the stud structure for the panels and the connecting means for securing the panels to a floor and ceiling with keyway members positioned in the panels to permit the use of key members for the interconnection of the panels in the building construction.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
166 words
The method of constructing panels for house construction comprising, placing a surface layer of fiberglass material in the bottom of a mold of dimensions for the desired panel and covering the bottom of the same; inserting metal rods across the mold in spaced parallel relationship and extending beyond the edges of the mold; applying a layer of acrylic material over the material and around the rods; positioning of insulation material in a plastic covering in spaced rows between the rods and extending across the mold; adding acrylic material with a filler around the rods and in the spacing between the insulation material to the depth of the insulation material and in contact with the lower fiberglass layer; applying a fiberglass mat over the top of the mold and in contact with the acrylic and filler material to saturate the same therewith; and allowing the layer of fiberglass material and mat with the insulation and rods between to harden and removing the completed panel from the mold.
Claim 2
Independent Claim
166 words
The method of constructing panels for house construction comprising, placing a surface layer of fiberglass material in the bottom of a mold of dimensions for the desired panel and covering the bottom of the same; inserting metal rods across the mold in spaced parallel relationship and extending beyond the edges of the mold; applying a layer of acrylic material over the material and around the rods; positioning of insulation material in a plastic covering in spaced rows between the rods and extending across the mold; adding acrylic material with a filler around the rods and in the spacing between the insulation material to the depth of the insulation material and in contact with the lower fiberglass layer; applying a fiberglass mat over the top of the mold and in contact with the acrylic and filler material to saturate the same therewith; and allowing the layer of fiberglass material and mat with the insulation and rods between to harden and removing the completed panel from the mold.
Claim 3
Dependent Claim
48 words
The method of constructing panels for house construction of claim 1 and including the placing of keyway strips at the ends of the molds parallel to the rods and the insulating matting and covering the same with acrylic and filler material to secure the same to the panels.
Claim 4
Dependent Claim
43 words
The method for constructing panels for house construction of claim 2 and including the adding of keyway strips intermediate the extent of the panel and facing the upper surface of the same with the acrylic material securing the keyway strips to the panel.
Claim 5
Dependent Claim
58 words
The method of constructing panels for house construction of claim 2 which includes inserting blanking frame members of a thickness and size into the mold to extend from top to bottom of same prior to laying of the initial fiberglass layer and the positioning of rods and insulation therein to provide for opening in the panels when completed.
Claim 6
Dependent Claim
26 words
The method of constructing panels for house construction of claim 4 and including adding a facing material to at least one side of the finished panel.
Claim 7
Dependent Claim
24 words
The method of constructing panels for house construction of claim 5 in which the rods are spaced a distance of approximately 16 inches apart.
Claim 8
Dependent Claim
41 words
The method of constructing panels of house construction of claim 6 and including the securing of the insulation packages to one another prior to the adding of the acrylic and filler and the positioning of the top layer of fiberglass mats.
Claim 9
Dependent Claim
83 words
The prefabricated panel including, an outer layer of fiberglass mat having a suitable facing material secured thereto; an inner core of insulating material extending in spaced rows across the width of the panel, a metal rod positioned in the space between each row of insulating material and secured to the insulating material and the outer layer of fiberglass mat by acrylic and filler material; and a top layer of fiberglass material secured to the insulating material and bonded thereto by an acrylic material.
Claim 10
Dependent Claim
83 words
The prefabricated panel including, an outer layer of fiberglass mat having a suitable facing material secured thereto; an inner core of insulating material extending in spaced rows across the width of the panel, a metal rod positioned in the space between each row of insulating material and secured to the insulating material and the outer layer of fiberglass mat by acrylic and filler material; and a top layer of fiberglass material secured to the insulating material and bonded thereto by an acrylic material.
Claim 11
Dependent Claim
20 words
The prefabricated panel of claim 8 in which the insulation material is confided in plastic sleeves filled with a polystyrene.
Claim 12
Dependent Claim
22 words
The prefabricated panel of claim 8 in which the rods extend parallel to one another and beyond the edges of the panel.
Claim 13
Dependent Claim
18 words
The prefabricated panel of claim 10 in which the rows of insulating material are secured to one another.
Claim 14
Dependent Claim
37 words
The prefabricated panel of claim 8 and including keyway members having outwardly facing slots positioned in each end of the panel and extending parallel to the rows of insulating material and through the extent of such end.
Claim 15
Dependent Claim
39 words
The prefabricated panel of claim 12 and in which the keyway members are made of an extruded plastic material and bonded to the panel with the acrylic material contacting the insulating material and the outer and inner fiberglass mats.
Claim 16
Dependent Claim
33 words
The prefabricated panel of claim 13 including an additional keyway member positioned intermediate the ends of the panel with the slot therein facing outwardly through one of the fiberglass mats of the panel.
Claim 17
Dependent Claim
82 words
The prefabricated panel of claim 14 and including a key member positioned in slots of one of said keyway members, said key member being formed of a wooden base having key surfaces extending along the extent of the same configuration as the slot or at least two ends of the key member with a connecting portion connecting the key surfaces; a wire mesh positioned over the wooden base, and a fiberglass mat covered with acrylic material thereon positioned over the wire mesh.
