Patent ID: 7785041

Claim:
A setting method for anchoring a fastening element ( 11 ; 41 ) having an outer diameter (A) and a mixing section ( 13 ; 43 ) in a constructional component ( 21 ) with a hardenable multi-component mass ( 31 ), the method comprising the steps of: drilling a borehole ( 22 ) in the constructional component ( 21 ) with a drill ( 36 ) until a borehole depth (T), which is at least by 5% greater than a necessary anchoring length (L) of the fastening element ( 21 ; 41 ), is reached; introducing the hardenable multicomponent mass ( 31 ) in the uncleaned borehole ( 22 ) with an injection tool; introducing, in the borehole ( 22 ), a predetermined amount of a filling material ( 34 ) with a predetermined distribution of particle sizes after introduction of the hardenable multi-component mass ( 31 ); inserting, in the borehole ( 22 ) the fastening element ( 11 ; 41 ) with the mixing section ( 13 ; 43 ) thereof first; and power-driving the fastening element ( 11 ; 41 ) into the filled borehole ( 22 ) with a rotary driving tool, with intermixing of the hardenable multi-component mass ( 31 ) with drillings ( 23 ) remaining in the borehole ( 22 ), until the necessary anchoring length (L) of the fastening element ( 11 ; 41 ) is reached.
