Definitions

  • the present invention generally relates to concrete slab construction.
  • the present invention is directed to a method for installing a thermally broken, cast-in-place concrete slab.
  • Concrete slabs that overhang or extend beyond exterior walls of buildings are extensions of a main building structure but are exposed to the outside and not thermally insulated from the main structure. Because of this, heat can be conducted into or out of a building through such concrete slabs. In this way, overhanging slabs can allow heat to escape from the interior of a building on cold days (or heat to enter a building on hot days), creating an inefficient area in the thermal envelope of the building.
  • Larkin discloses the use of a "relatively thin flat panel of thermal insulating material" between the overhanging concrete slab and the main structure with holes in the material for reinforcing bars to pass through.
  • Larkin does not include any transverse force bars passing through the insulating barrier.
  • Witschi and Penzkofer do include transverse force bars passing through an insulating barrier but include additional components such as articulation elements or face plates that tend to increase the complexity of the installation process.
