Abstract:

An interlocking and insulating form pattern assembly used in creating a wall structure for receiving a poured concrete. A first elongate form structure has a substantially rectangular configuration with a height, a length and a width. The first form structure includes a plurality of interiorly and arcuately formed walls which define in combination a first and second pluralities of interconnecting and vertically and longitudinally spaced and parallel extending concrete filling passageways. Tongue and groove portions are extend from first and second sides of each form structure and at least along selected oppositely facing surfaces so as to provide a stacking arrangement of a plurality of form structures to establish a desired height of the wall structure. The stacking arrangement sets upon a footing and receives a poured concrete to fill the vertically and longitudinally extending concrete filling passageways of the forms. A method is also disclosed for producing a form pattern assembly used in creating the wall structure and includes the steps of extruding an elongate form with a first of the pluralities of concrete filling passageways, as well as the tongue and groove portions for interlockingly stacking the completed form structures.
