Abstract

A structural wall unit system includes a plurality of wall units having at least one face being a rotational tessellation. The face has at least two irregular sides extending therefrom. Each side of the wall units have at least one spacer or connector configured to engage other wall units. The structural wall unit system also includes a plurality of starter course units, where each starter course unit has a portion of a primary rotational tessellation element having at least one irregularly shaped side that is an image of the first side or the third side. Each irregularly shaped side of the starter course units have at least one spacer or connector configured to engage the wall units, and the starter course units have at least one straight side. The starter course units and the wall units are configured for assembly as a structural wall having a natural, random appearance.

Claims (10)

1. A structural wall unit system comprising,

a plurality wall units each having a front face configured for substantially vertical orientation comprised of x primary rotational tessellation elements, where x is an integer equal to or greater than 1, and said primary element comprising a first irregularly shaped side extending in a generally radial direction relative to a first vertex; a second side extending in a generally radial direction relative to said first vertex and being rotationally spaced from said first side by a first angle of 360 degrees divided by n, where n is an integer greater than or equal to 3, said second side being substantially a rotational image of said first side; a third irregularly shaped side extending in a generally radial direction from a second vertex, said second vertex being spaced apart from said first vertex; and a fourth side extending in a generally radial direction from said second vertex, said fourth side being substantially a rotational image of said third side, said fourth side being rotationally spaced from said third side by a second angle of 360 degrees divided by m, where m is an integer greater than or equal to 2; and each side of said wall units having at least one spacer or connector configured to engage other said wall units; and

a plurality of starter course units, each starter course unit comprising a portion of a said primary rotational tessellation element having at least one irregularly shaped side that is an image of said first side or said third side, each irregularly shaped side of said starter course units having at least one spacer or connector configured to engage said wall units, and said starter course units having at least one straight side;

wherein said starter course units and wall units are configured for assembly as a structural wall having a natural, random appearance.

2. A structural wall unit system as in claim 1 , wherein said wall units comprise first and second units, said first units comprising at least one primary tessellation element and second units comprising at least two primary tessellation elements, said second units being a different size than said first units.

3. A structural wall unit system as in claim 1 , wherein said wall unit comprises said spacers which are configured to form a pre-determined gap between wall units when assembled.

4. A structural wall unit system as in claim 1 , wherein each said wall unit comprises said connectors which are configured to setback upper ones of said wall units relative to lower ones of said wall units.

5. A structural wall unit system as in claim 1 wherein each said wall unit comprises said connectors which are “S” shaped.

6. A structural wall unit system as in claim 1 further comprising

a plurality of side and top units, each side and top unit comprising a portion of a said primary rotational tessellation element having at least one irregularly shaped side that is an image of said first side or said third side, each irregularly shaped side of said side units having at least one spacer or connector configured to engage said wall units, and said side and top units having at least one straight side.
