Abstract
Es descrito un perno para roca, para su uso como perno de anclaje o perno de friccion en una perforacion formada en un cuerpo de roca. El perno para roca incluye un elemento alargado con un paso axial interno que tiene un extremo anterior y un extremo posterior opuesto. Una embolo se encuentra configurada para ser apoyada por el elemento alargado en su extremo anterior, con el embolo apoyando adicionalmente un ariete que se proyecta hacia fuera mas alla del extremo anterior del elemento alargado. Durante el uso, el ariete se encuentra configurado para apoyarse contra el cuerpo de roca de modo de impartir una fuerza de apisonamiento sobre el embolo y forzar el embolo hacia el paso axial interno del elemento alargado y, por lo tanto, desviar hacia fuera una parte del elemento alargado de modo que quede encajado dentro del perforacion.
