Patent ID: 6854229

Claim:
An elongate sleeve tie designed to receive a casting form tie for use in manufacturing a composite wall structure comprising an insulating layer sandwiched between first and second structural layers, the elongate sleeve tie comprising an elongate sleeve body formed from a material having high thermal resistance, said elongate sleeve body comprising: a mesial segment positionable through a passage within an insulating layer when the insulating layer is in a desired spaced-apart relationship between two casting forms used to manufacture a composite wall structure; a first anchor segment adjacent to a first side of the mesial segment and positionable within a first space between the insulating layer and a first casting form for placement of a first layer of a hardenable structural material within the first space during manufacture of a composite wall structure; a second anchor segment adjacent to a second side of the mesial segment and positionable within a second space between the insulating layer and a second casting form for placement of a second layer of a hardenable structural material within the second space during manufacture of a composite wall structure, wherein at least one of said first and second anchor segments further comprises means for anchoring said elongate sleeve tie within a hardened layer of structural material; and a central recess configured to receive therein a casting form tie used to connect first and second casting forms together during manufacture of a composite wall structure.
