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.
