Abstract
The present invention provides a method of constructing a foundation substructure and a building involving pouring concrete between resilient sheets of insulating material, preferably polystyrene, so as to form a complete concrete shell.
Claims17
A method of constructing a building, comprising the steps of:
- a) erecting a plurality of panels to define the walls;
- b) installing a support rail at the height of a floor or roof;
- c) attaching at least one sheet of material to the support rail so as to define a floor or roof
- d) pouring concrete between the panels of insulating material and over the at least one sheet of material so as to form the walls and floor or roof of the building
A building wherein at least part of one wall comprises two sheets of insulating material between which is a layer of concrete.
The building of claim 7 wherein said insulating material is polystyrene.
A method of constructing a foundation substructure comprising the steps of:
- a) laying a concrete foundation;
- b) securely fixing outside perimeter members to said foundation to define the outside perimeter of a wall;
- c) positioning foundation blocks comprising an outside perimeter sheet and an inside perimeter sheet held in spaced relation to each other against said outside perimeter members, wherein the outside perimeter sheet is taller than the inside perimeter sheet;
- d) securely fixing inside perimeter members against the inside perimeter of said foundation blocks;
- e) filling said foundation block with concrete to the height of the inside perimeter sheet;
- f) building the inside foundation structure up with hardcore;
- g) overlaying the hardcore with an insulating sheet such that the top of the insulating sheet is level with the height of the inside perimeter sheet;
- and
- h) pouring a concrete floor slab over said insulating sheet to the height of external perimeter sheet.
The method of claim 12 wherein said outer perimeter members and said inner perimeter members are softwood battens.
A foundation substructure comprising at least one foundation wall comprising two sheets of material between which is a layer of concrete.
The foundation substructure of claim 15 wherein said foundation wall is adjacent to a further sheet of insulating material and part of the upper surface of said foundation wall and said further sheet of insulating material support a slab of concrete.
