Connectors used in manufacturing composite wall structures to substantially prevent forms from being displaced in response to pressure generated by concrete poured between the forms. In a completed composite wall structure, the connectors extend through two structural layers and an insulating layer positioned therebetween. The composite wall structures are formed by positioning the insulating layer between and in a spaced-apart relationship to the two forms. The connectors are subsequently inserted through the insulating layer and the forms. As concrete is then poured into spaces between the forms and the insulating layer, a bearing surface on a form retention segment, which extends beyond the outer surface of the forms, abuts the forms and prevents them from moving away from the insulating layer. The bearing surface is either directly positioned on the form retention segment or on a form locking device attached to the form retention segment. After the concrete hardens, the forms are removed and the form retention segments are optionally detached from the remainder of the connector. The surface of the connectors optionally includes an adhesion promotion material or mechanical anchoring structure to improve the bond between the connectors and the structural layers.

[ What is claimed and desired to be secured by United States Letters Patent is:] [1.] 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.
