Insulated Concrete Walls

Abstract

An insulated concrete wall includes a first form board, a second form board, a plurality of spacers, a plurality of rebar rods, a quantity of poured concrete and at least one insulation sheet. Each spacer includes at least one vertical passage for receiving a vertical rebar rod and a horizontal passage for receiving a horizontal rebar rod. The plurality of spacers are attached between the first and second form boards to create a concrete cavity. The quantity of concrete is poured into the cavity. The sheet of insulation may be attached to one or both form boards. The at least one insulated sheet may be replaced by an additional form board and the plurality of spacers. The additional form board would create an additional cavity, which would be filled with an insulation material. Alternatively, the two outer cavities may be filled with concrete and the center cavity filled with insulation.

1 . An insulated concrete wall comprising:
 a first form board and a second form board;   a plurality of rebar rods;   a plurality of spacers, each one of said plurality spacers having a horizontal passage and a vertical passage, said horizontal passage is sized to receive at least one rebar rod of said plurality of rebar rods, said vertical passage is sized to receive at least one rebar rod of said plurality of rebar rods, one side of said plurality of spacers are attached to an inside surface of said first form board and an opposing side of said plurality of spacers are attached to an inside surface of said second form board to create a concrete cavity, said plurality of rebar rods are inserted horizontally and vertically into said plurality of spacers;   a quantity of concrete is poured into said concrete cavity; and   an insulation sheet is attached to at least one of said first and second form boards.   
     
     
         2 . The insulated concrete wall of  claim 2  wherein:
 said first and second form boards are fiber cement boards sourced from James Hardie company. 
 
     
     
         3 . An insulated concrete wall comprising:
 a first form board, a second form board and a third form board;   a plurality of rebar rods;   a plurality of spacers, each one of said plurality spacers having a horizontal passage and a vertical passage, said horizontal passage is sized to receive at least one rebar rod of said plurality of rebar rods, said vertical passage is sized to receive at least one rebar rod of said plurality of rebar rods, one side of said plurality of spacers are attached to an inside surface of said first form board and an opposing side of said plurality of spacers are attached to an inside surface of said second form board to create a concrete cavity, one side of said plurality of spacers are attached to an outside surface of said second form board and an opposing side of said plurality of spacers are attached to an inside surface of said third form board to create an insulation cavity, said plurality of rebar rods are inserted horizontally and vertically into said plurality of spacers in said concrete cavity;   said concrete cavity is filled with a quantity of concrete; and   said insulation cavity is filled with a quantity of insulation.   
     
     
         4 . The insulated concrete wall of  claim 3 , further comprising:
 a fourth form board, one side of said plurality of spacers are attached to an outside surface of said third form board and an opposing side of said plurality of spacers are attached to an inside surface of said fourth board to create a second concrete cavity, said plurality of rebar rods are inserted into said plurality of spacers in said second concrete cavity, said second concrete cavity is filled with said quantity of cement.   
     
     
         5 . The insulated concrete wall of  claim 3 , further comprising:
 a fourth form board, one side of said plurality of spacers are attached to an outside surface of said first form board and an opposing side of said plurality of spacers are attached to an inside surface of said fourth board to create a second insulation cavity, said second insulation cavity is filled with said quantity of insulation.   
     
     
         6 . The insulated concrete wall of  claim 3  wherein:
 said first, second and third form boards are fiber cement boards sourced from James Hardie company.
