Insulated integral concrete wall forming system
First Claim
1. A method of making a wall panel, comprising:
- pouring a first concrete layer into a form with a perimeter edge and a bottom;
supporting an insulation layer above the first concrete layer so as to create a space therebetween, the support being provided by a plurality of connectors extending through the insulation layer and having a first end extending through the first concrete layer to engage the bottom of the form;
pouring a second concrete layer on top of the insulation-layer before the first concrete layer has cured, the connectors having a second end extending into the second concrete layer; and
curing the first and second layers substantially simultaneously.

Abstract
Precast insulated concrete wall panels are made by pouring a first concrete layer into a form. An insulation layer is then supported above the first concrete layer so as to create a space therebetween. The second concrete layer is then poured on top of the insulation layer before the first concrete layer has cured. Connectors are anchored in the first and second concrete layers so as to tie the layers together. After the first and second concrete layers have cured, the wall panels can be lifted, transported, and assembled into a wall structure. An intermediate layer of concrete can be poured into the air gap of the wall panels such that the panels define the form for the intermediate concrete layer and become an integral part of the wall structure. The wall structure may extend below or above grade and may be multi-tiered. The edges of the wall panels are contoured so as to interlockingly matingly engage when assembled into the wall structure. Notches may be provided in the upper edge of the wall panels so as to receive floor or roof joists.

6. A wall panel comprising:
-
a first concrete layer;
a second concrete layer cured substantially simultaneously with the first concrete layer;
an insulation layer adjacent to second concrete layer;
an air gap between the insulation layer and the first concrete layer; and
a plurality of connectors each having a first end extending through the first concrete layer, to support the insulation layer in spaced relation to the first concrete layer so as to define the air gap, and a second end embedded in the second concrete layer without extending through the second concrete layer. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)
