Composite insulated wall

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 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;
• 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;
• 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 section 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 comprising a flange rigidly connected to each of said shear connectors and bearing against said layer of insulating material between said insulating material and said first layer of concrete.
