TIE SYSTEM FOR INSULATED CONCRETE PANELS

摘要

An insulated concrete panel comprising an insulation layer having one or more openings extending therethrough, a first concrete layer adjacent to a first surface of the insulation layer, a second concrete layer adjacent to a second surface of the insulation layer, and a wall tie received within one or more of the openings. The wall tie includes a central section received within the one or more openings of the insulation layer, a first concrete engaging at least partially embedded within the first concrete layer, and a second concrete engaging section embedded within the second concrete layer. The second concrete engaging section has a maximum width that is larger than a maximum width of the central section. The central section of the wall tie is configured to transfer shear forces and resist delamination forces between the first and second concrete layers.

主权项

1. A method of making an insulated concrete panel, said method comprising:
(a) creating a plurality of substantially cylindrical tie openings that each extend through an insulation layer from a first surface of said insulation layer to an opposite second surface of said insulation layer; (b) pouring a first layer of concrete; (c) placing said insulation layer on said first layer of concrete, such that said first surface of said insulation layer is in contact with said first layer of concrete; (d) inserting a wall tie into a plurality of said tie openings, with each of such wall ties comprising first and second end sections opposing a central section, wherein after said pouring of step (b) and said inserting of step (d), said first end section of each of said wall ties is at least partially embedded within said first layer of concrete; and (e) pouring a second layer of concrete over said second surface of said insulation layer, wherein after said pouring of step (e), said second end portion of said wall tie is at least partially embedded within said second layer of concrete.
