Abstract
Removable form for use in pouring concrete walls, the form being comprised of a high strength, impact resistant, light weight material and being constructed to provide thermal insulation of concrete poured between two of the forms. The forms are each comprised of a face plate backed by an insulative support structure. The insulative support structure has a honeycomb construction filled with an insulative material, the honeycomb construction providing strength to the insulative support structure to prevent bending or distortion. A supporting frame is further provided as a structural supporting backing for the insulative support section to increase its resistance to bending.
Claims9
A removable concrete form for use in casting concrete, the removable concrete form comprising:
- a monolithic insulative supporting section having a front face and a rear face and having a pair of parallel spaced apart side walls, spaced apart transverse top and bottom walls, and a plurality of intersecting partition walls forming a lattice in said supporting section;
- insulative material located in said lattice;
- a planar face plate secured against the front face of said insulative supporting section;
- and
- a supporting frame joined to the rear face of said insulative supporting section for providing structural support to said insulative supporting section, said supporting frame including at least a pair of ribs attached to the rear face of said insulating supporting section, said insulative supporting section and said supporting frame forming an integrally joined monolithic structure.
