Abstract
Abstract The present invention comprises an improved composite wall structure which includes a pair of outer poured concrete layers (31, 32) which are separated by a high density foam insulating panel (18) which is mounted between the concrete layers (31, 32) and includes a plurality of tie mechanisms (14, 19) for holding the insulated layer in place while the concrete is being poured and hardened, wherein the holding means (14, 19) comprises metal rods and are low heat conductive rods (14,19) such as polyglass impregnated plastic rods upon which a pair of holding spools (21, 22) are mounted which engage opposite sides of the insulating panel so as to hold it in a predetermined position. Also disclosed is a novel corner form arrangement.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
138 words
An insulating wall comprising: two spaced outer layers of form-poured concrete; a high density insulating board disposed between said outer layers; a plurality of rods extending perpendicularly through said insulating layer and further extending substantially from respective outer surfaces of said outer layers; and a plurality of retainer means mounted to receive and immovably hold a rod for fixing the lateral position of said rods with respect to said insulation layer, whereby said rods abut said form during pouring of said concrete to retain said interior layer substantially immovably during pouring and are retained in said concrete after curing for forming a mechanical connection between said interior layer and each of said outer layers, wherein said retainer means comprises a pair of spools formed with central openings that can be inserted into opposite sides of said insulating board.
Claim 2
Dependent Claim
138 words
An insulating wall comprising: two spaced outer layers of form-poured concrete; a high density insulating board disposed between said outer layers; a plurality of rods extending perpendicularly through said insulating layer and further extending substantially from respective outer surfaces of said outer layers; and a plurality of retainer means mounted to receive and immovably hold a rod for fixing the lateral position of said rods with respect to said insulation layer, whereby said rods abut said form during pouring of said concrete to retain said interior layer substantially immovably during pouring and are retained in said concrete after curing for forming a mechanical connection between said interior layer and each of said outer layers, wherein said retainer means comprises a pair of spools formed with central openings that can be inserted into opposite sides of said insulating board.
Claim 3
Dependent Claim
34 words
An insulating wall according to claim 1, wherein said spools each' have an enlarged outer flange that can be depressed into the surface of said board and a central portion smaller than said flange.
Claim 4
Dependent Claim
30 words
An insulating wall according to claim 2 wherein said spools also each have an inner portion which is larger than said central portion for locking said spool to said board.
Claim 5
Dependent Claim
34 words
An insulating wall according to claim 3 wherein ribs are formed on the innerside of said flange to lock the spool to said board to prevent said spool from turning relative to said board.
Claim 6
Dependent Claim
24 words
An insulating wall according to claim 3 wherein said flange includes index means to indicate the orientation of the sped relative to said board.
Claim 7
Dependent Claim
59 words
An insulating wall according to claim 1 wherein said rods have projections thereon and a rod can be inserted through the central openings of a pair of said spools and locking means on each of said spools for locking the spools to said rod to hold said board in a predetermined spatial position between said outer layers of concrete.
Claim 8
Dependent Claim
45 words
An insulating wall board according tc claim 6 wherein said central openings are not round so that said rods and projections can pass therethrough in one angular orientation and said projections can be locked to said spools by rotating said rods relative to said spools.
Claim 9
Dependent Claim
24 words
An insulating wall according to claim 7 including a depression in said flange for receiving said projections to lock said rod to said flange.
Claim 10
Dependent Claim
20 words
An insulating wall according to claim 8 including ramps formed on said spools between said depressions and said central opening.
Claim 11
Dependent Claim
20 words
An insulating wall board according to claim 1 wherein said rods are made of material which has low thermal conductivity.
Claim 12
Dependent Claim
17 words
An insulating wall board according to claim 10 wherein said rods are made of polyglass impregnated plastic.
Claim 13
Dependent Claim
25 words
An insulating wall according to claim 1 wherein said insulating board is formed of two sections which are pivotally connected together to form a corner.
Claim 14
Dependent Claim
15 words
An insulating wall according to claim 12 wherein said two sections have 45° mating ends.
Claim 15
Dependent Claim
20 words
An insulating wall according to claim 13 wherein fiberglass sheet material is attached to said sections to form a hinge.
Claim 16
Dependent Claim
44 words
An insulating wall comprising: two spaced outer layers of concrete, an insulating board disposed between said outer layers, means for holding said insulating board in a predetermined position relative to at least one of said outer layers and said means having low thermal conductivity.
Claim 17
Dependent Claim
44 words
An insulating wall comprising: two spaced outer layers of concrete, an insulating board disposed between said outer layers, means for holding said insulating board in a predetermined position relative to at least one of said outer layers and said means having low thermal conductivity.
Claim 18
Dependent Claim
17 words
An insulating board according to claim 10 wherein said rods may be made of fiberglass reinforced polyester.
Claim 19
Dependent Claim
22 words
An insulating board according to claim 1 wherein said rods have undercuts at their ends to mechanically tie said concrete slabs together.
Claim 20
Dependent Claim
18 words
An insulating board according to claim 12 wherein said two sections are joined together by spun bond plastic.
