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.
