Patent ID: 7918055

Claim:
A construction spacer for an interface comprising a horizontal surface and a vertical surface meeting at a corner comprising: a first panel; a second panel; a hinge that is unitary with the first and second panels and couples the first panel to the second panel, wherein the hinge allows the spacer to be positioned at the interface such that the first panel overlies the horizontal surface and the second panel overlies the vertical surface, wherein the hinge is foldably coupled to the first panel along a longitudinal edge of the first panel and is foldably coupled to the second panel along a longitudinal edge of the second panel; and wherein the hinge further comprises at least two additional zig zag folds to allow the hinge to be increased and decreased in width in a manner effective to help distortionally separate the first panel from the second panel such that the hinge absorbs distortion forces to reduce induced distortion among panels when the panels conform to an irregularity in an underlying surface; a first plurality of longitudinally elongated dimples projecting from the first panel in a manner effective to support the first panel from the horizontal surface in a manner to define a fluid flow space between the first panel and the horizontal surface, said dimples being filled with a cured cement; and a second plurality of longitudinally elongated dimples projecting from the second panel in a manner effective to support the second panel from the horizontal surface in a manner to define a fluid flow space between the second panel and the vertical surface, said dimples being filled with a cured cement.
