Abstract
Bulón de anclaje expansible, del tipo que comprende un bulón cilíndrico alargado que comporta un elemento de expansión en forma de cuña, cuyo diámetro, inicialmente reducido, aumenta hacia la extremidad del bufón, sensiblemente hasta su diámetro principal, figurando dispositivos de expansión situados a lo largo de una parte del elemento de expansión, sensiblemente en el interior de la periferia del bulón, estando relacionados unos con otros por un tirante que pasa sobre la citada extremidad del bulón y que forma parte integrante de los dispositivos de expansión, caracterizado porque el tirante y los dispositivos de expansión están realizados de material de estructura laminar y poseen ramas cuyas extremidades se ensanchan en forma de alas que rodean sensiblemente, en forma de manguito, el elemento de expansión de forma cónica del bulón, constituyendo las zonas delanteras de los bordes, dispositivos de apriete y de anclado, y su parte posterior dispositivos de enclavamiento que sobrepasan lacircunferencia exterior del bulón y cuya parte inferior está separada del elemento de expansión del bulón.
