摘要： The invention relates to a connection means for providing a positive and/or non‑positive connection between at least two connection partners, wherein the connection means has at least a first region which engages with the first connection partner via a positive and/or non‑positive engagement, and at least a second region is provided which engages with the at least second connection partner via a positive and/or non‑positive engagement. The object of making available a connection means by which a non‑positive and/or positive connection can be provided between at least two connection partners in a simple manner and cost‑effectively and which meets high safety requirements is achieved in that at least the second region of the connection means has a region formed from a material which is flat at least in certain regions and which consists of an Fe alloy with shape memory properties, which region, during activation, ensures the positive and/or non‑positive engagement with the second connection partner as a result of a change in shape.

摘要： After a rock anchor (1), in particular an expandable friction tube anchor (1), comprising an anchor bolt (2) has been inserted into a pre-sunk borehole with an end sleeve (4) first, an adapter (6) having a liquid inflow and outflow is arranged on a sleeve (3). On the one hand, a holding pressure which secures the adapter (6) to the sleeve (3) is produced via a holding-pressure line (8). On the other hand, fluid flows into the anchor bolt (2) via an expansion line (7) and starts to fill said bolt. In the process, the increase in pressure (inflation pressure) causes the anchor bolt (2) to expand in the borehole, with the result that its outer surface presses against the borehole wall and thus secures the rock anchor (1) in the borehole. A gas supply connected to the adapter (6) makes it possible for a gas under pressure, in particular compressed air, to be introduced into the anchor bolt (2) before and/or after the expansion thereof. The compressed gas is relieved following the removal of the adapter (6) (pressure equalization) and conveys the fluid contained in the anchor bolt (2) virtually completely from the anchor (1).

摘要： A roof anchor (10) for supporting an underground mine roof (12) has an elongated shaft (16) with a head (20) formed at one end. The head (20) supports a washer (23) and a roof supporting plate (24) that surrounds the mouth of a blind bore (14) formed upwardly into the roof. A resin capsule (32) is positioned within the blind bore (14) above the roof anchor (10). The shaft (16) of the roof anchor has an adjustably securable annular washer (26) surrounding the shaft. The annular washer (26) is fixed in a position so that when the resin capsule (32) is ruptured to release the resin to bind the roof anchor (10) within the bore hole, the resin completely fills the bore hole from the blind end of the bore to the rigid annular washer (26) fixed to the shaft of the roof anchor. By making the position of the annular washer axially adjustable, the roof anchor may be utilized with varying amounts of resin as conditions at the mine site require and still cause the resin to be subjected to a compressive force within the bore hole in the space between the end of the bore hole and the annular washer.
