摘要： An expansion bolt including an anchor bolt having an expansion section, and further including an expansion sleeve which surrounds the anchor bolt and which can be expanded by retracting the expansion section, and a spring element arranged on the anchor bolt. The spring element can be tensioned by inserting the anchor bolt into a bore hole and can retract the expansion section of the anchor bolt into the expansion sleeve when it is released. An indicator element indicates when a rated tension of the spring element is reached.

摘要： An expansion anchor including a bolt and an expansion sleeve surrounding the bolt is provided, the bolt having: an expansion cone in the region of the front end of the bolt, which expansion cone radially enlarges the expansion sleeve when moved into same; a threaded section for introducing tensile forces into the bolt; a shoulder that limits a movement of the expansion sleeve away from the expansion cone; and at least one anti-rotation protrusion for inhibiting a rotation of the expansion sleeve in relation to the bolt, the protrusion originating at the shoulder and protruding radially outwards on the bolt. The axial length of the anti-rotation protrusion is smaller than the pitch of the threaded section arranged on the bolt.

摘要： A disassembly method for an anchor that is anchored in a hole and that has an anchor bolt is provided, whereby, during the disassembly procedure, a torque is applied to the bolt of the anchor that is anchored in the hole and, in this process, the anchor bolt is stressed until it breaks. An anchor which has a head and whose bolt has an engaging profile so that a torque can be applied to the anchor bolt is also provided.
