Abstract: 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.

Abstract: A sensor arrangement, for example, on an anchor bolt, including at least one sensor (10). At least one bypass element (20) with a dilatant material is arranged in the area of the sensor (10), whereby impact forces that act upon the sensor (10) can be dissipated via the dilatant material of the bypass element (20).

Abstract: A direct tension indicator (2), including a base element (11) and a cover element (13) that is arranged on the base element (11) and at least one indicator element (4) that is arranged between the base element (11) and the cover element (13) in order to display an axial force acting between the base element and the cover element. The indicator element (4) includes a dilatant material.

Abstract: One or more embodiments of the present invention relate to a torque-limited attachment device, having a first head piece with at least one shaped element for the purpose of establishing a positive-fit connection to an attachment tool, and having a second head piece which has at least one threading, wherein both head pieces are connected to each other, forming at least one predetermined breaking point which breaks at a limit torque between the two head pieces such that a first breakaway surface, the same being functionally assigned to the first head piece, and a second breakaway surface, the same being functionally assigned to the second head piece, are created, and wherein at least the second head piece has a base material inside, the same having a corrosion-resistant surface coating.

Abstract: A method for the production of torque-limited fastening devices, which each have a first head element with a contact for a fastening tool, and a second head element that is joined to the first head element via a welded joint that shears off at a predefined limit torque, said method providing a plurality of first head elements and second head elements having the same geometry, and in each case, a first head element and a second head element are welded together in a welding process that creates the welded joint. At least two welding processes are carried out employing at least one different welding parameter, so that different limit torques can be obtained for parts having the same geometry. A fastening device on a concrete anchor.
