A method for building a mechanical secured block structure, including placing a footer block on a desired surface, inserting two respective starter bar nuts into the footer block, inverting the footer block, placing a first concrete masonry unit over respective first and second anchor bars, aligning the first concrete masonry unit with the footer block, placing second and third footer blocks adjacent the first footer block, placing a second concrete masonry unit adjacent the first concrete masonry unit, positioning each respective concrete masonry unit to equally straddle two adjacent footer blocks, positioning respective anchor bars atop respective concrete masonry units, and bolting respective concrete masonry units to respective footer blocks to interconnect the two respective concrete masonry units and the three respective footer blocks to define a contiguous wall. Each respective masonry unit and each respective footer block are post tensioned to be under compression. |

1. A method for constructing a structure from a mechanical secured block building system with concrete masonry units, comprising:
a) placing first and second respective anchor bars on a foundation surface; b) placing a first concrete masonry unit over the respective starter anchor bars; c) placing third and fourth respective anchor bars into respective upper extended recessed channels; d) placing respective first and second tendon through bolts into respective through apertures in respective third and fourth anchor bars; e) threadedly engaging respective first and second tendon through bolts with respective first and second threaded apertures in respective first and second anchor bars; f) placing fifth and sixth respective anchor bars adjacent the first concrete masonry unit; g) placing a second concrete masonry unit over the fifth and sixth anchor bars; h) placing seventh and eighth respective anchor bars into respective upper extended recessed channels in the second concrete masonry unit; i) placing respective third and fourth tendon through bolts into respective third and fourth through apertures in respective seventh and eighth anchor bars; j) threadedly engaging respective third and fourth tendon through bolts with respective third and fourth threaded apertures in respective third and fourth anchor bars; k) positioning a third concrete masonry unit over the first and second concrete masonry units wherein the third concrete masonry unit straddles the first and second concrete masonry units; l) placing respective ninth and tenth anchor bars into respective upper extended recessed channels of the third concrete masonry unit; m) placing respective fifth and sixth tendon through bolts into respective fifth and sixth through apertures in the respective ninth and tenth anchor bars; and n) threadedly engaging respective fifth and sixth tendon through bolts with respective fifth and sixth threaded apertures in respective ninth and tenth anchor bars; wherein each respective concrete masonry units further comprises: a masonry longitudinal length, a masonry width measured perpendicularly to the masonry longitudinal length, wherein the masonry width which is essentially one half the longitudinal length and which is substantially uniform along the masonry longitudinal length, a masonry top surface, the masonry top surface being substantially planar, a masonry bottom surface, the masonry bottom surface being substantially planar, a masonry height which is essentially one half the longitudinal length and which is measured between the masonry top and masonry bottom surfaces, the masonry height being substantially uniform along the masonry longitudinal length, a first through-cavity formed through the masonry unit from the top surface to the bottom surface, a second through-cavity formed through the masonry unit from the top surface to the bottom surface, a third through-cavity formed through the masonry unit from the top surface to the bottom surface, and an anchor bar channel recessed formed in the masonry top surface and oriented substantially along the masonry longitudinal length; wherein each respective anchor bar further comprises: (i) a first set of apertures, the first set of apertures comprising a first non-threaded aperture and a first threaded aperture, wherein the first non-threaded aperture and the first threaded aperture are located in first and second diagonally opposing quadrants of a coordinate system defined by a longitudinal centerline of the anchor bar and a line that is perpendicular to the longitudinal centerline; and (ii) a second set of apertures neighboring the first set of apertures, the second set of apertures comprising a second non-threaded aperture that is substantially the same as the first non-threaded aperture, and a second threaded aperture that is substantially the same as the first threaded aperture, wherein the second non-threaded aperture and the second threaded aperture are located in third and fourth diagonally opposing quadrants of the coordinate system but spaced longitudinally from the first set of apertures, wherein the first set of apertures is aligned with the first through-cavity and the second set of apertures is aligned with the third through-cavity when the anchor bar is placed into the anchor bar recessed channel of the masonry unit; and wherein a width of the anchor bar is smaller than a width of the recessed channel of the masonry unit; and wherein each respective through tendon further comprises: (i) a first fastener end and a second fastener end, (ii) a head portion at the first fastener end, (iii) a stem portion rigidly affixed to the head portion, the stem portion comprising a threaded portion at the second fastener end; wherein the head portion does not fit through the first non-threaded aperture; wherein the stem portion slides freely through the first non-threaded aperture; and wherein the threaded portion is configured to threadably engage the first threaded aperture. |
