Abstract

Perno de anclaje expansible perfeccionado, caracterizado por presentar una parte de barra de forma regular, destinada a introducirse en el oportuno agujero, y que se prolonga en una parte roscada, destinada a permanecer en el exterior, presentando la citada parte de barra unas muescas en cuña en las que se alojan otras tantas cuñas libres, exteriormente dentadas para agarre preferente en un sentido, siendo mantenidas dichas cuñas inicialmente en sus alojamientos por una envoltura tubular que luego se rasga y/o retira, de tal manera que las cuñas libres, al tratar de desplazarse longitudinalmente en sus alojamientos, por las formas coordinadas de cuñas y alojamientos, tienden también a "expandirse" en componente radial del movimiento "clavándose" en las paredes internas del agujero, y reteniendo muy fuertemente al perno.
