Patent ID: 7913469

Claim:
A concrete load-bearing wall comprising: a first layer of prefabricated concrete panels spaced apart by a first plurality of cast-in-place concrete wall vertical ribs, wherein each of the prefabricated concrete panels of the first layer of prefabricated concrete panels have at least two protruding edges; a second layer of prefabricated concrete panels spaced apart by a second plurality of cast-in-place concrete wall vertical ribs disposed therein, wherein each of the prefabricated concrete panels of the second layer of prefabricated concrete panels have at least two protruding opposing edges, further wherein the second layer of prefabricated concrete panels is positioned opposite the first layer of prefabricated concrete panels such that each of the prefabricated concrete panels of the first layer of prefabricated concrete panels overlap a portion of at least one prefabricated concrete panel of the second layer of prefabricated concrete panels; and a heat insulating layer covering an inner surface of each of the prefabricated concrete panels to form a continuous heat insulating barrier, the heat insulating layer conforming to the inner surface of the prefabricated concrete panels, wherein a union of the heat insulating layer and the prefabricated concrete panels form a prefabricated concrete unit; wherein the prefabricated concrete unit formed by the union of the heat insulating layer and the prefabricated concrete panels of the first layer is cross-linked with the prefabricated concrete unit formed by the union of the heat insulating layer and the prefabricated concrete panels of the second layer, such that the at least two protruding edges of the prefabricated concrete panels of the first layer of prefabricated concrete panels contact the prefabricated concrete unit formed by the union of the heat insulating layer and the prefabricated concrete panels of the second layer, forming a single, heat insulated wall.
