Abstract:
A connector for use in the manufacture of a composite wall structure comprising:an elongate shaft including:a form retention segment disposed at an end thereof and positionable through a passage within a casting form;a mesial segment positionable through a passage within an insulating layer when the insulating layer is in a desired spaced-apart relationship with the casting form; andan anchor segment disposed between said form retention segment and said mesial segment and positionable within a space between the insulating layer and the casting form for placement of a layer of a hardenable structural material within said space during manufacture of a composite wall structure,wherein at least the mesial segment of the elongate shaft comprises a material having a high thermal resistance;retention means, removably attached to the elongate shaft adjacent to the mesial segment, for preventing significant movement of the insulating layer relative to the elongate shaft in at least one axial direction; andform locking means, associated with the form retention segment, for preventing substantial movement of the casting form relative to the elongate shaft in at least one axial direction.
