A tool () for cleaning a drilled hole (), including a tool shank () that, relative to the shank axis (A), has an axial attachment end () and an opposite axial cleaning end (), as well as at least one conveying element () for removing drilling dust () from the drilled hole (). The conveying element () is attached to the tool shank () and arranged in the axial direction like a helix around the tool shank (). The conveying element () is configured as a channel () that is open in the direction of the attachment end (). A method for cleaning a drilled hole by such a tool () is also disclosed.

An anchoring sleeve for anchoring a fastening element in a bore hole of a component by a hardenable compound is disclosed. The anchoring sleeve has a sleeve-like base body with a first end, with a second end, as well as with several axially successive extension sections arranged between the ends which are each configured to be cone-like and their diameter respectively increases in the direction of the first end.

Anchoring sleeve

A setting tool for inserting an anchor rod into a borehole filled with a curable mass or filled with a cartridge containing a curable mass is disclosed. The setting tool includes a housing, which has a receptacle for the anchor rod, into which the anchor rod can be inserted in the longitudinal direction and in which the anchor rod can be fixed. At least one clamping element is tilted at an angle from the longitudinal axis of the receptacle and is supported in a guide in the receptacle in such a way that the clamping element can be moved from a receiving position, in which the anchor rod can be inserted into the receptacle in the longitudinal direction, to a clamping position, in which the anchor rod is fixed in the receptacle in the circumferential direction, by rotating the housing relative to the anchor rod.

A fastening element () for anchoring in a borehole () with a hardenable compound () has a shaft () extending along a longitudinal axis (), a mixing element (), and a profiling element () with radially protruding profiling sections.

Fastening element

A setting method of anchoring a fastening element () in a constructional component () with a hardenable multi-component mass () includes drilling a borehole () in the constructional component () with a drill () until a borehole depth (T), which is at least by 5% greater than a necessary anchoring length (L) of the fastening element (), is reached; introducing the hardenable multicomponent mass () in the uncleaned borehole (), inserting, in the borehole () the fastening element () with its mixing section () first, and power-driving the fastening element () into the filled borehole () with a rotary driving tool, with intermixing of the hardenable multi-component mass () with drillings () remaining in the borehole (), until the necessary anchoring length (L) of the fastening element () is reached.

A head part () for a multi-chamber tube bag () with a multi-component mass which can be pressed out, having a main chamber () for a first component and two secondary chambers () for two other components, has a disk-shaped contact surface () for the multi-chamber tube bag () surrounding a press-out opening (). At the contact surface (), a plurality of raised portions () project toward the multi-chamber tube bag () and are provided at the head part () for narrowing the outlet regions () of the two secondary chambers () of the multi-chamber tube bag () when the multi-chamber tube bag () bears against the contact surface ().
