Definitions
- the present subject matter relates to construction. More particularly, the present subject matter relates to industrialized construction of walls.
- Insulating concrete form as known as insulated concrete form, is a system of formwork for reinforced concrete usually made with a rigid thermal insulation that stays in place as a permanent interior and exterior substrate for walls, floors, and roofs.
- the forms are interlocking modular units that are dry-stacked, without mortar, and filled with concrete. The units lock together and create a form for the structural walls or floors of a building.
- Insulating concrete forms are usually manufactured from insulating materials, for example, polystyrene foam, polyurethane foam, cement-bonded wood fiber, cement-bonded polystyrene beads, cellular concrete, and thastyron—a mixture of cement, water and recycled expanded polystyrene.
- insulating materials for example, polystyrene foam, polyurethane foam, cement-bonded wood fiber, cement-bonded polystyrene beads, cellular concrete, and thastyron—a mixture of cement, water and recycled expanded polystyrene.

Description
- This application claims priority to U.S. Provisional Patent Application No. 62/522,381, filed Jun. 20, 2017, the entire contents of which is incorporated herein by reference in its entirety.
- The present subject matter relates to construction. More particularly, the present subject matter relates to industrialized construction of walls.
- Insulating concrete form, as known as insulated concrete form, is a system of formwork for reinforced concrete usually made with a rigid thermal insulation that stays in place as a permanent interior and exterior substrate for walls, floors, and roofs. The forms are interlocking modular units that are dry-stacked, without mortar, and filled with concrete. The units lock together and create a form for the structural walls or floors of a building.
- Insulating concrete forms are usually manufactured from insulating materials, for example, polystyrene foam, polyurethane foam, cement-bonded wood fiber, cement-bonded polystyrene beads, cellular concrete, and thastyron—a mixture of cement, water and recycled expanded polystyrene.
- Reinforcing steel bars are usually placed inside the forms before concrete if poured to give the concrete flexural strength. After the concrete has cured, the forms are left in place permanently.
- Nevertheless, the currently available insulating concrete forms have several drawbacks, for example they are prone to leakage of water at the outer surface of the insulating concrete form, especially at the border lines between adjacent insulating concrete forms; thermal insulator layers add extra weight to the insulating concrete forms; placement of reinforcing steel bars in the space where concrete is to be poured is cumbersome, and following construction of a wall with the currently available insulating concrete forms there is a need to plaster and/or paint the outer surfaces of the insulating concrete forms.
- Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this subject matter belongs.

FIG. 2 schematically illustrates, according to an exemplary embodiment, a cross-side view of afirst panel 10. The embodiments illustrated inFIG. 2 are relevant to either thefirst panel 10, or thesecond panel 20, or thefirst panel 10 and thesecond panel 20. According to this embodiment, thefirst panel 10 may comprise afirst panel surface 110 and asecond panel surface 120 enclosing at least onehollow compartment 130. Similarly, thesecond panel 10 may comprise a first panel surface and a second panel surface enclosing at least one hollow compartment. - Each
hollow compartment 130 is filled with an insulating material. According to one embodiment, the insulating material is a thermal insulating material, for example air, foam, and the like. According to another embodiment, the insulating material is an acoustic insulating material, for example an acoustic insolating fiber, insulating wool and the like. According to a preferred embodiment, thehollow compartment 130 is filled with air. As a result, the at least onefirst panel 10 and the at least onesecond panel 20 have an intrinsic insulating capacity. Therefore, according to one embodiment, there is no need to add an insulating material to the insulatingconcrete form system 1.
