US 10,704,260 B2 · Tie system for insulated concrete panels

Abstract

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.

Dependent claims

An insulated concrete panel comprising:

an insulation layer comprising a tie opening extending therethrough;
first and second concrete layers disposed on opposite sides of said insulation layer;
and
a tie system extending through said tie opening and tying said first and second concrete layers to one another, wherein said tie system comprises
a central portion at least partly received in said tie opening,
a first end section at least partly embedded in said first concrete layer, and
a second end section at least partly embedded in said second concrete layer,
wherein, prior to being embedded in concrete, said tie system is configured to shift about an axis of rotation extending through said central portion from a collapsed configuration, in which a maximum width of said first and second end sections is less than a maximum width of said tie opening, to an expanded configuration, in which the maximum width of said first and second end sections is greater than the maximum width of said tie opening.

An insulated concrete panel comprising:

an insulation layer comprising a substantially cylindrical tie opening extending therethrough;
first and second concrete layers disposed on opposite sides of said insulation layer;
and
a tie system extending through said tie opening and tying said first and second concrete layers to one another,
wherein said tie system comprises an elongated first structural member and an elongated second structural member,
wherein each end of said first structural member is embedded in one of said first and second concrete layers,
wherein each end of said second structural member is embedded in one of said first and second concrete layers,
wherein said first and second structural members cooperatively form an X-shape, with an intersection of said first and second structural members being located within said tie opening,
wherein the maximum width of said tie system embedded in said first concrete layer is greater than the maximum width of said tie opening,
wherein the maximum width of said tie system embedded in said second concrete layer is greater than the maximum width of said tie opening,
wherein said first structural member comprises a projection,
wherein said second structural member comprises a recess,
wherein said projection is received in said recess at said intersection of said first and second structural members to thereby connect said first and second structural members to one another in a manner that transfers shear forces between said first and second concrete layers and prevents delamination of said first and second concrete layers,
wherein said tie system comprises a hub portion having a rounded outer profile, wherein said hub portion is received in said tie opening,
wherein said first and second structural members comprise respective first and second hubs, wherein said hub portion comprises first and second barriers coupled to said first and second hubs respectively, wherein said first and second barriers have a rounded outer profile.
