Non-composite insulated concrete sandwich panels

Abstract

A non-composite insulated concrete sandwich panel system, and specifically a system for sandwiching together a layer of concrete with a rigid insulation sheet tied between the layers, that reduces or eliminates separation or cracking in the rigid insulation sheet, attributable to undesirable adhesion of the layer of concrete to the rigid insulation sheet. A slip-faced insulation panel is formed from an insulation panel, with a lower slip-sheet adhered to the lower face and an upper slip sheet adhered to the upper face. The slip-faced insulation panel is placed between the lower concrete layer and the upper concrete layer, the lower slip-sheet slip-able upon the lower concrete layer, and the upper slip-sheet slip-able on the upper concrete layer.

1 . A method for forming an insulated concrete sandwich panel, including the steps of:
 a) pouring a lower concrete layer on a ground surface;   b) covering an insulation panel with a lower slip-sheet and an upper slip sheet to form a slip-faced insulation panel, the lower slip-sheet adhered to a lower face of the insulation panel and the upper slip-sheet adhered to an upper face of the insulation panel, the lower slip-sheet selected to freely slip upon the lower concrete layer, and the upper slip-sheet selected to freely slip upon an upper concrete layer;   b) placing the slip-faced insulation panel upon the lower concrete layer;   c) attaching the slip-faced insulation panel to the lower concrete layer with a tie, the tie penetrating through the slip-faced insulation panel, the tie extending into the lower concrete layer below the slip-faced insulation panel, and the tie protruding above the slip-faced insulation panel;   d) pouring the upper concrete layer on the upper slip-sheet of the slip-faced insulation panel; and   e) curing the lower concrete layer and the inner concrete layer to form the insulated concrete sandwich panel, the lower slip-sheet free to slip upon the lower concrete layer, and the upper slip-sheet free to slip upon the upper concrete layer.   
     
     
         2 . The method for forming an insulated concrete sandwich panel of  claim 1  additionally including the step of:
 f) tilting the insulated concrete sandwich panel up and off of the ground surface. 
 
     
     
         3 . (canceled) 
     
     
         4 . An insulated concrete sandwich panel comprising:
 a slip-faced insulation panel formed from an insulation panel, the insulation panel having a lower face and an upper face, and the slip-faced insulation panel having a lower slip-sheet adhered to the lower face and an upper slip sheet adhered to the upper face;   a lower concrete layer and an upper concrete layer;   the slip-faced insulation panel placed between the lower concrete layer and the upper concrete layer;   the slip-faced insulation panel tied to the outer concrete layer, and the slip-faced insulation panel tied to the upper concrete layer; and   the lower slip-sheet of the slip-faced insulation panel formed from a slip-able material and slip-able upon the lower concrete layer, and the upper slip-sheet of the slip-faced insulation panel formed from a slip-able material and slip-able on the upper concrete layer.   
     
     
         5 . The insulated concrete sandwich panel of  claim 4 , wherein: a tie penetrates through the slip-faced insulation panel, the tie extends into the lower concrete layer, and the tie extends into the upper concrete layer. 
     
     
         6 . (canceled) 
     
     
         7 . The method according to  claim 1 , further comprising the step of:
 f) selecting the lower slip-sheet to include a metal foil material to freely slip upon the lower concrete layer; and   g) selecting the upper slip-sheet to include a metal foil material to freely slip upon the upper concrete layer.   
     
     
         8 . The insulated concrete sandwich panel of  claim 4 , wherein:
 the lower slip-sheet includes a metal foil material to freely slip upon the lower concrete layer; and   the upper slip-sheet includes a metal foil material to freely slip upon the upper concrete layer.
