Abstract

A constructional brick, for use in the forming of a wall structure capable of resisting high gravity and lateral loads of both a uniform and cyclical character, exhibits a generally solid rectangular exterior configuration defining an xyz Cartesian coordinate system, an x-axis capable of defining a width axis of the wall structure, a y-axis defining the directionality of the wall structure, and a z-axis defining a vertical axis of the wall structure. One xz end surface of each building block displays a positive y-axis deep key geometry and each opposing xz end surface thereof comprises a negative y-axis deep key geometry complementally interlockable to the positive geometry of the opposite xz surface, in which y-axis deep key dimensions of the respective positive and negative deep key geometries exist in a range of about 10 to about 50 percent of the x-axis dimension of the brick, in which an upper xy surface of the brick includes a number of z-axis recesses, each having an xy plane lower surface, and a lower xy surface of the brick including a corresponding number of integral z-axis male members complementary interlockable with the z-axis recesses. Use of such bricks provides a substantially rigid and load-resistant interlock between horizontally and vertically contiguous bricks, when joined together as components of a wall structure.
