METHOD OF SETTING A SELF-DRILLING, CHEMICALLY ANCHORABLE FASTENING ELEMENT AND A SELF-DRILLING CHEMICALLY ANCHORABLE FASTENING ELEMENT

摘要

A method of setting a self-drilling chemically anchorable fastening element(11;51) includes mounting of an adaptor (31) on the second end (18; 58) of theshaft(12; 52) of the fastening element (11; 51), connecting the drilling power tool(41) with the adaptor (31), the adaptor having an engagement element (32) forthe tool chuck (42), drilling a borehole (7) in the constructional component(6)with the self-drilling fastening element (11; 51), rotating the fasteningelement(11; 51) in a first rotational direction (R1), forcing out the hardenable masslocated in the receiving space of the shaft of the fastening element from thefastening element with an ejection device, and pre-stressing the fasteningelement (11; 51) after at least partial hardening of the hardenable mass (15;55)by rotating the adaptor (31) in a second rotational direction (R2) oppositethefirst rotational direction (R1), with at least a section of the adaptor (31)beingdisplaced in a direction of the first end (17; 57) of the shaft (12; 52) ofthefastening element.
