Insulated Hollow Core Concrete Forming System for Walls and Slabs

An Insulated hollow core concrete forming system directed towards constructing insulated hollow core concrete wall and slab structures, comprising:

• at least one Modular formwork unit, wherein the Modular formwork unit is composed and formed of insulative material and has one or more longitudinal void formers integrated in-between two spaced parallel side panels to define
• a forming cavity of a hollow core section disposed to receive concrete or other hardening material to form an insulated hollow core concrete wall and slab structures;
• a furring strip assembly, is held between adjacent Modular formwork units tightly to join them together, wherein the furring strip assembly has an I-shaped cross section defined by two side retaining flanges and a connecting web spanning between the retaining flanges;
• and
• wherein said Modular formwork unit constructs the insulated hollow core concrete wall and slab structures and utilizes the longitudinal void formers as they extend between the two spaced parallel side panels to shape the hollow cores within the hardened concrete of the constructed structures, the Modular formwork unit and their longitudinal void formers remain in place as part of the constructed structures providing insulation.
