Abstract

Clavo perfeccionado, para hincamiento en agujeros de anclaje pretaladrados en la roca o la piedra, deformable elásticamente en sentido radial y que presenta, en una dimensión por lo menos, espesor que supera al diámetro del agujero de anclaje; caracterizado por componerse fundamentalmente de un alma (2; 9) y dos flancos aproximadamente semicirculares (3) que se juntan al alma simétricamente respecto a la línea central de ella, con lo cual se produce un perfil en S corrido.
