1. A tie system for an insulated concrete panel, said tie system comprising:
a first structural member comprising a first hub and a pair of first extension members coupled to said first hub, wherein said first extension members extend outwardly from said first hub in different directions; and a second structural member comprising a second hub and a pair of second extension members coupled to said second hub, wherein said second extension members extend outwardly from said second hub in different directions; wherein said first and second hubs are configured to be rotatably coupled to one another in a manner that permits rotation of said first and second hubs relative to one another on an axis of rotation extending through said first and second hubs, wherein when said first and second hubs are rotatably coupled to one another said tie system is shiftable between a collapsed configuration and an expanded configuration by rotating said first and second structural members relative to one another on said axis of rotation, wherein when said tie system is in said collapsed configuration said tie system presents opposing ends and said tie system is elongated along an axis of elongation extending between said opposing ends, wherein said axis of rotation is orthogonal to said axis of elongation when said tie system is in said collapsed configuration, wherein at least one of said first and second hubs includes one or more protuberances, wherein the other of said first and second hubs includes one or more cavities, wherein said first and second hubs are configured to engage with each other, with at least one of said protuberances being received in at least one of said cavities, to thereby hold said first and second structural members in a plurality of different relative rotational positions, wherein, at distal ends thereof, each of said first and second extension members includes an enlarged end portion comprising oppositely facing heel and toe portions, and wherein an entirety of each of said first and second extension members is a continuous unitary structure of one-piece rigid construction. |
