Component modular foam based system for construction of concrete structures

Abstract

A method and structure for constructing a waterproof concrete structure using a central core of rigid foam attached to exterior castings, cemented together and anchored to a foundation.

1 . A method for constructing a concrete structure, comprising the steps of: 
 providing a structural foam block and anchoring the foam block to a foundation pad,    attaching one or more castings to the structural foam block with a liquid foam that expands and hardens as it cures.    
   
   
       2 . The method of  claim 1  further including the step of affixing the castings to the structural foam block by applying cementations material.  
   
   
       3 . The method of  claim 1  wherein the structural foam block is made of polystyrene or polyethylene.  
   
   
       4 . The method of  claim 1  wherein an anchoring hole is formed in the structural foam block and further including the step of placing a cementations material in the anchoring hole to cause the structural foam block to be anchored the foundation pad.  
   
   
       5 . The method of  claim 4  further including the step of using wiring placed in the anchoring hole to attach a casting to the structural foam block.  
   
   
       6 . The method of  claim 1  wherein a casting is pre-cast from an impression made from a natural rock, or, a casting is pre-cast from a mold artistically made to look like rock.  
   
   
       7 . The method of  claim 1  where a casting is made from fiber-reinforced concrete (FRC) and filled with a closed-cell foam.  
   
   
       8 . The method of  claim 1  where the liquid foam is selected from the group consisting of a urethane foam, a latex foam, a phenolic foam and an organic foam.  
   
   
       9 . The method of  claim 1  further including the step of applying rebar armature to the structural foam block whereby the concrete structure is reinforced.  
   
   
       10 . The method of  claim 1  where the concrete structure is a water fountain.  
   
   
       11 . A concrete structure, comprising: 
 a structural foam block anchored to a foundation pad, and    one or more castings attached to the structural foam block with a liquid foam that expands and hardens as it cures.    
   
   
       12 . The concrete structure of  claim 11  where the castings are affixed to the structural foam block with cementations material.  
   
   
       13 . The concrete structure of  claim 11  wherein the structural foam block is made of polystyrene or polyethylene.  
   
   
       14 . The concrete structure of  claim 11  wherein an anchoring hole is formed in the structural foam block and a cementations material is placed in the anchoring hole to anchor the structural foam block to the foundation pad.  
   
   
       15 . The concrete structure of  claim 14  where wiring is placed in the anchoring hole to attach a casting to the structural foam block.  
   
   
       16 . The concrete structure of  claim 11  wherein a casting is pre-cast from an impression made from a natural rock, or, a casting is pre-cast from a mold artistically made to look like rock.  
   
   
       17 . The concrete structure of  claim 11  where a casting is made from fiber-reinforced concrete (FRC) and filled with a closed-cell foam.  
   
   
       18 . The concrete structure of  claim 11  where the liquid foam is selected from the group consisting of a urethane foam, a latex foam, a phenolic foam and an organic foam.  
   
   
       19 . The concrete structure of  claim 11  further including rebar armature attached to the structural foam block whereby the rebar armature reinforces the concrete structure.  
   
   
       20 . The concrete structure of  claim 12  where the concrete structure is a water fountain.
