Use devices for mechanically secured block assembly systems

A mechanical secured block building system for constructing structures with concrete masonry units, the system comprising:

• (a) a masonry unit, the masonry unit being made of concrete and comprising:
• 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 substantially 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;
• (b) an anchor bar, the anchor bar comprising:
• 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
• c) a fastener, the fastener comprising:
• (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;
• and
• further comprising a first wall system and a second wall system;
• wherein each respective wall system further comprises at least two respective block courses, each respective block course being placed contiguously as touching wall systems;
• and wherein the second wall system has alternating longitudinal and perpendicular blocks that intersect and connect with the first wall system through a perpendicular block unit and anchor bar to create an integral wall system of multiple walls;
• and wherein a long tension bar is placed on the respective bottom course of each respective wall system to create a mechanical secured block building system grade beam.
