ANCHORING SYSTEM FOR A SUPPORT IN CONSTRUCTION, AND METHOD FOR USING SAME

摘要

Anchoring system is appropriate for solid rock and concrete (2) and any firm bearing system. The anchor rod (4) of for example a threaded bar out of a shape memory alloy (SMA) is held in the armature bore (3) with a filling compound (5) as anchoring means. For filling the achoring bore (3) between anchor rod (4) and wall of the armature bore (3) a heat resistant filling compound (5) of a polymer connection on a two-component-basis or such on a cementous basis is used. Then the anchor rod (4) is heated by heat input over its butt that is emerging the filling compound on its austenit phase, which pre tensions the anchor rod (4). Finally, after the cooling of the filling compound (5) the anchor rod (4) is cooling of to ambient temperature. A counter bearing board (10) lays on the outer wall (1) around the port of the armature bore (3) and is tensed up with the anchor rod (4).
