A mechanical expansion anchor and tapered plug for use therein having particular application in combination with resin grouting materials. The anchor includes conventional shell structure having a plurality of radially expansible leaves with internal surfaces opposing compression surface portions of a tapered camming plug. Components of a resin mix inserted in a drill hole between the blind end thereof and the end of a bolt carrying the expansion anchor flow around the tapered plug and through axial passageways therein. The plug is distinguished by the provision of axial grooves for passage of resin components in the compression surfaces of the plug.
Dispositif d'ancrage mécanique à expansion avec noix conique, en particulier pour usage avec un matériau de scellement à base de résine. Ce dispositif possède une coquille d'expansion de construction classique, à lames multiples s'écartant radialement sous l'effort de compression exercé sur leur face interne par la noix. Les éléments du mélange de scellement, introduits au fond du trou, sous l'extrémité du boulon muni du dispositif d'ancrage selon cette invention, se répandent autour de la noix conique et dans les rainures axiales pratiquées sur la face de compression de cette dernière.
