Integrated, post-tensioned, building construction system

The present invention relates an integrated, post-tensioned building construction system that utilizes a rectangular array of interlocking block components for the shell of building structures. Internal tendons that pass through the interlocking blocks are affixed to beams at the base or foundation of the building walls and terminate above beams atop the building walls. The ends of tendons receive mechanical fasteners that are tightened to the beams and/or foundation. The tendons serve to maintain the integrity of the interlocking block components, which cannot come apart when the tendons are tightened. Build stops secured to tendons help to stabilize the interlocking block components during construction. With interlocking blocks fabricated from a compressible material, like concrete-and-aggregate, the tendons are tensioned to induce a compressive load on the material. Inducing compression in the structure by tensioning the internal tendons augments the strength of the entire building by introducing an internal compressive stress that partially counteracts the tensile stresses caused by external loads applied to the structure, such as by windstorms, seismic events, or settling of the foundation.
