Abstract
Abstract An insulated wall includes first and second spaced apart layers of concrete having a layer of insulating material sandwiched therebetween. Extending through the insulative layer are a plurality of spike connectors having their opposite ends protruding into the two concrete layers and having their central portions extending through the insulating material. One of the opposite ends of the spike connectors is pointed so as to permit it to be punched through the insulative layer. The opposite ends of the spikes each include a holding surface facing at least partially toward the central insulative layer and holding the concrete layers against movement away from the insulative layer. C-shaped connectors may also be used in a similar fashion with hook ends hooked over elongated cables extending within the two concrete layers so as to tie them together.

Claim 1
Independent Claim
412 words
An insulated wall comprising: first and second spaced apart layers of concrete; a layer of insulating material sandwiched between said first and second layers of concrete; a plurality of elongated shear connectors having a high R-value, and extending through said layer of insulating material; each of said shear connectors comprising a first end portion extending into said first layer of concrete, a second end portion extending into said second layer of concrete, and a central portion extending through and within said layer of insulating material; said first and second end portions of said shear connectors each having, respectively, a holding surface facing at least partially toward said insulating layer and engaging said first and second layers of concrete, respectively, to hold said first and second layers of concrete against movement away from said layer of insulating material wherein said first end portion, said second end portion and said central portion are integrally formed having a uniform width from the first end portion to the second end portion inclusively; said second end portions of each of said shear connectors having a pointed end and tapering outwardly toward said layer of insulation to a wide point having a cross-section approximately the same in shape and size as the cross-section of said central portion; said wide point located between said holding surface and said pointed end of said second end portion and further wherein said holding surface of said second end portion tapers inwardly and uniformly from the wide point to the central portion; wherein each of said first, second, and central portions of each of said shear connectors has a longitudinal axis, said longitudinal axes of said first, second, and central portions extending in the same direction; further comprising a hook connector made of a high R-value material and having a central portion and first and second opposite hook shaped ends, said central portion of said hook connector extending through said layer of insulating material and said first and second opposite hook shaped ends embedded in said first and second layers of concrete respectively; wherein a first and a second elongated member are within said first and second layers of concrete respectively and extend parallel to said insulating material, said first and second hook shaped ends of said hook connector hooked over said first and second elongated members respectively; and further wherein said first and second hook shaped ends extend partially into said layer of insulating material and are separated by a narrow gap.
