Abstract

A rebar positioning device with opposite ends for positioning adjacent to a form face of at least one form panel may include a support rod having opposite ends and an outer surface, with at least a portion of the outer surface being threaded. At least one bar clip may be movably mounted on the support rod. An orientation of the at least one bar clip on the support rod is adjustable, and a position of the at least one bar clip on the support rod is adjustable.

at least one abutment cap removably mounted on one of the ends of the support rod, the abutment cap having an abutment face for abutting against the form face of the at least one form panel, the abutment cap having a cavity which is open at a first end of the cap to receive the support rod and which is closed at an opposite second end of the cap to form the abutment face and to prevent movement of the end of the support rod through the second end of the cap; and

wherein a longitudinal position of the abutment cap on the support rod is adjustable to adjust a longitudinal position of the abutment face with respect to the support rod;

wherein the cavity is defined by a cavity surface threaded to engage threads on the support rod such that rotation of the abutment cap with respect to the support rod in the first rotational direction causes the cap to move longitudinally outward with respect to the support rod and thereby move the abutment face longitudinally outward, and rotation of the abutment cap with respect to the support rod in the second rotational direction causes the cap to move longitudinally inward with respect to the support rod to move the abutment face longitudinally inward.

2. 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 face 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;

a plurality of reinforcing bars being positioned in the concrete receiving space;

at least one bar clip rotatably mounted on the support rod, the clip having a base portion receiving a section of the support rod and a pair of arm portions removably gripping one of the reinforcing bars, the arm portions extending outwardly from the base portion such that the arm portions extend in a radial direction from the support rod;

wherein the at least one bar clip is rotatable on the support rod to adjust the radial direction orientation of the arm portions of the bar clip with respect to the support rod;

wherein the at least one bar clip is rotatable on the support rod to adjust a longitudinal position of the bar clip relative to the opposite ends of the support rod;

wherein the at least one bar clip is threadedly mounted on the support rod such that rotation of the clip with respect to the support rod in the first rotational direction advances the bar clip in the first longitudinal direction along the support rod and rotation of the bar clip with respect to the support rod in the second rotational direction advances the bar clip in the second longitudinal direction along the support rod, the second longitudinal direction being opposite of the first longitudinal direction.

3. 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 face 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;

at least one bar clip rotatably mounted on the support rod, the clip having a base portion receiving a section of the support rod and a pair of arm portions configured to removably grip a reinforcing bar, the arm portions extending outwardly from the base portion such that the arm portions extend in a radial direction from the support rod;

9. The system of claim 3 additionally comprising a plurality of reinforcing bars being positioned in the concrete receiving space.

10. The system of claim 3 wherein the at least one form panel comprises a pair of form panels with substantially opposing form faces, the form faces defining the concrete receiving space therebetween, the opposite ends of the panel positioning device being each located adjacent to the one of the form faces.

11. The system of claim 3 wherein the at least one bar clip has a cavity configured to receive a portion of a reinforcing bar and a channel configured to receive the support rod.
