Abstract
Abstract A plastic shear connector for forming an insulated wall having an improved fiber composite or plastic shear connector which is used to form a composite wall formed of an insulating sheet and one or more concrete layers wherein the shear connectors are formed with tapered ends and have a holding portion injection molded and mounted on the center portion of the shear connector and which is inserted through the insulating board as the composite wall is formed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
129 words
An insulating wall comprising two spaced outer layers of concrete, a high density insulating board mounted between said outer concrete layers, a plurality of shear connectors of high R material mounted in said insulating board and with opposite ends extending outwardly so as to lie in the same plane into said spaced outer concrete layers and said opposite ends formed with tapered surfaces so that said shear connectors prevent said spaced outer concrete layers from separating from said insulating board, wherein said shear connectors are formed with flat opposite ends and a central cylindrical shear connector sleeve which extends through said insulating board, and wherein said central cylindrical shear connector sleeves are formed with a flange on one end which bears against said insulating board to provide proper location.
Claim 2
Dependent Claim
129 words
An insulating wall comprising two spaced outer layers of concrete, a high density insulating board mounted between said outer concrete layers, a plurality of shear connectors of high R material mounted in said insulating board and with opposite ends extending outwardly so as to lie in the same plane into said spaced outer concrete layers and said opposite ends formed with tapered surfaces so that said shear connectors prevent said spaced outer concrete layers from separating from said insulating board, wherein said shear connectors are formed with flat opposite ends and a central cylindrical shear connector sleeve which extends through said insulating board, and wherein said central cylindrical shear connector sleeves are formed with a flange on one end which bears against said insulating board to provide proper location.
Claim 3
Dependent Claim
23 words
An insulating wall according to claim 1 wherein said shear connectors are formed of fiber composition material which has a high R number.
Claim 4
Dependent Claim
29 words
An insulating wall according to claim 1 wherein the angle of taper of said tapered surfaces being in the range of 2 to 7 degrees with the untapered portion.
Claim 5
Dependent Claim
15 words
An insulating wall according to claim 3 wherein the angle of taper is 5.37 degrees.
Claim 6
Dependent Claim
96 words
An insulating wall comprising two spaced outer layers of concrete, a high density insulating board mounted between said outer concrete layers, a plurality of shear connectors of high R material mounted in said insulating board and with opposite ends extending into said spaced outer concrete layers and said opposite ends formed wit tapered surfaces so that said shear connectors prevent said spaced outer concrete layers from separating form said insulating board, and including a shear collar mounted in said insulating board and formed with a plurality of openings through which said plurality of shear connector extend.
Claim 7
Dependent Claim
96 words
An insulating wall comprising two spaced outer layers of concrete, a high density insulating board mounted between said outer concrete layers, a plurality of shear connectors of high R material mounted in said insulating board and with opposite ends extending into said spaced outer concrete layers and said opposite ends formed wit tapered surfaces so that said shear connectors prevent said spaced outer concrete layers from separating form said insulating board, and including a shear collar mounted in said insulating board and formed with a plurality of openings through which said plurality of shear connector extend.
Claim 8
Dependent Claim
35 words
An insulating wall according to claim 5 wherein said shear collar has a tapered portion in which said plurality of openings are formed and said shear connectors extending outwardly and downwardly through said shear collar.
