Abstract

Procedimiento y aparato mejorados para evaluar tendones de postensado, donde el aparato utiliza una cabeza de posicionamiento colocada directamente dentro de la bolsa y contra el anclaje sin hacer contacto con las cuñas al asentarse el aparato en el tendón. Desde esta posición el aparato evalúa el tendón mediante marcado, medición del tendón y/o determinación de su ubicación con precisión y fiabilidad aumentadas.Improved method and apparatus for evaluating post-tensioned tendons, where the apparatus utilizes a positioning head placed directly within the pocket and against the anchor without contacting the wedges as the apparatus is seated in the tendon. From this position the apparatus evaluates the tendon by marking, measuring the tendon, and/or determining its location with increased accuracy and reliability.
