System for insulated concrete composite wall panels

An insulated concrete panel, said panel comprising:

• an insulation layer having one or more openings extending therethrough;
• a first concrete layer adjacent to a first surface of said insulation layer;
• a second concrete layer adjacent to a second surface of said insulation layer;
• and
• a shear connecter received within one or more of said openings in said insulation layer, wherein said shear connector includes—
• an elongated core member comprising a first end and a second end;
• a flanged end-piece secured to one of said first end or said second end of said core member,
• wherein said flanged end-piece comprises a base section connected to said elongated core, a flange section extending outwardly from said base section, and a support element comprising an insulation engagement surface that is spaced from said flange section and engages said insulation layer,
• wherein said flange section is spaced from said insulation layer and embedded within said first concrete layer,
• wherein said shear connector is configured to transfer shear forces between said first concrete layer and said second concrete layer, and to prevent delamination of said first concrete layer and said second concrete layer.

A shear connector for use with an insulated concrete panel, said shear connector comprising:

• an elongated core member comprising a first end and a second end;
• and
• a flanged end-piece removably secured to one of said first end or said second end of said core member,
• wherein at least a portion of said flanged end-piece includes a maximum diameter that is larger than a maximum diameter of said core member,
• wherein said shear connector is configured to transfer shear forces,
• wherein said flanged end-piece comprises a base section and a flange section extending from said base section,
• wherein said flanged end-piece additionally comprises at least one support element comprising an insulation engagement surface spaced from the flange section,
• wherein said core member comprises a substantially hollow cylinder, and wherein said core member includes a separation member extending across an interior of said core member so as to prevent fluid flow though the interior of said core member.

An insulated concrete panel, said panel comprising:

• an insulation layer having one or more openings extending therethrough;
• a first concrete layer adjacent to a first surface of said insulation layer;
• a second concrete layer adjacent to a second surface of said insulation layer;
• and
• a shear connector received within one or more of said openings in said insulation layer,
• wherein said shear connector includes
• an elongated core member comprising a first end and a second end;
• a flanged end-piece secured to one of said first end or said second end of said core member, wherein said flanged end-piece is at least partially embedded within said first concrete layer,
• wherein said shear connector is configured to transfer shear forces between said first concrete layer and said second concrete layer, and to prevent delamination of said first concrete layer and said second concrete layer,
• wherein said core member comprises a substantially hollow cylinder with a separation member extending across an interior of said core member so as to prevent fluid flow through the interior of said core member.
