Abstract:
A constructional component for a wall structure definable in an xyz Cartesian coordinate system, capable of resisting high gravity and lateral loads, both uniform and cyclical, the component comprising:a solid building block, formed of a structural material, having a generally rectangular exterior configuration definable in said xyz Cartesian system, an x-axis thereof comprising a width axis of said wall structure, a y-axis thereof comprising the directionality of said wall structure, and a z-axis thereof comprising a vertical axis of the wall structure, in which one xz end surface of each building block comprises 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 said positive geometry of said opposite yz surface, in which a ratio of the x-axis width of a base of each positive and negative deep key geometry of each opposing xy end surface comprises about at least fifty percent of the entire x-axis width of each block, in which each y-axis deep key dimension of said respective positive and negative deep key geometries also comprises a range of about eight to about twenty five percent of the x-axis dimension of said block, in which said block includes a plurality of vertical cavities extending the entire z-axis length therethrough, said cavities separated by a web portion having respective non-parallel opposite vertical surfaces which narrow in the negative z-axis direction, said cavities including rectilinear interior ledges at their respective interfaces with respective top and bottom xy surfaces of said block, said ledges comprising respectively negative and positive complementally interlockable rectilinear structures, each having a z-axis dimension in a range of about five to about twenty five percent of the x-axis dimension of the block,whereby a substantially rigid and load-resistant interlock between horizontally and vertically contiguous blocks, when joined as a component of a wall structure, is resultant therefrom.
