method for fixing ankerstangen in concrete and verbundmasse.

摘要

In order to improve the force transmission between an anchoring bolt (8) which is inserted in a drilled hole (1) in concrete, artificial stone or other stone and which is held by means of a composite mass (4), and the concrete or stone mass bounding the drilled hole (1), the invention proposes that steel needles (6) be inserted in an irregular pattern at least in one undercut bonding region of the composite mass (4), a suitable composite mass (4) being designed such that steel needles (6) are embedded in it.
