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.

Description

TECHNICAL FIELD[0001]An insulated concrete sandwich panel system for use in a tilt-up wall, and specifically a system for sandwiching a rigid insulation panel within two layers of concrete.BACKGROUND OF THE INVENTION[0002]Insulated concrete panel systems are commonly employed in building structures requiring higher insulation and a heat transfer resistance or an “R-value,” which conventional concrete can provide only with additional insulating materials. Due to the expense and unwieldy size of large, composite wall panels, “tilt-up” concrete building wall-panels are often used. Tilt-up wall-panels are poured into forms on a ground surface, allowed to cure and then tilted-up and into position around the building. Often, insulating the tilt-up wall-panels is desired, especially in climate controlled warehouses and storage facilities, and in storage buildings for refrigerated, perishable goods. Concrete panels can be insulated from the interior with a rigid insulation panel, typically ...

AI Technical Summary

Benefits of technology

The invention provides a system for insulating concrete panels used in building structures. The system includes a lower concrete layer and a slip-faced insulation panel that is placed on top of the lower concrete layer. The insulation panel is designed to expand and contract independently of the concrete layers, reducing rippling and cracking. The system also includes a tie that connects the insulation panel to the lower concrete layer, ensuring stability and preventing the insulation panel from moving or shifting during the curing process. Overall, the system provides better insulation and stability for tilt-up walls and refrigerated storage facilities.

Problems solved by technology

Due to the expense and unwieldy size of large, composite wall panels, “tilt-up” concrete building wall-panels are often used.

However, with sandwiching together layers of concrete with a rigid insulation sheet, shrinkage in the curing process and later thermal expansions or contractions in the concrete can cause rippling and cracking of the interior insulation panel or sheet.
