Adjustable rebar positioning device

A forming system for concrete, comprising:

• at least one form panel having a form face and a concrete receiving space adjacent to the form face;
• at least one insulation panel positioned in a spaced relationship to the form face of the form panel, the at least one insulation panel having opposite panel faces with one of the panel faces facing the form faces of the form panel;
• at least one insulation panel positioning device having opposite ends with at least one of the ends being positioned adjacent to the form face of the form panel, the panel positioning device comprising:
• a support rod having opposite ends and an outer surface, at least a portion of the outer surface being threaded;
• at least one positioning plate movably mounted on the support rod, the positioning plate having at least one abutment face for positioning against one of the panel faces of the insulation panel, a position of the at least one positioning plate on the support rod being adjustable, the plate having a passage receiving a portion of the support rod, the passage being defined by a passage surface with at least a portion of the passage surface being threaded to engage threads on the support rod such that rotation of the positioning plate with respect to the support rod in a first rotational direction causes the positioning plate to move in a first longitudinal direction with respect to the support rod to move the abutment face in the first longitudinal direction, and rotation of the position plate with respect to the support rod in a second rotational direction causes the positioning plate to move in a second longitudinal direction with respect to the support rod to move the abutment face in the second longitudinal direction.
