Abstract
Official abstract text for this publication.
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 ).
First claim
Opening claim text (preview).
What is claimed is: 1. An anchor bolt comprising: a screw bolt and an expansion element on one end of the screw bolt, an opposite end of the screw bolt passing through a washer, a screw nut being arranged above the washer, and a sensor arrangement being arranged between the screw nut and the washer, the sensor arrangement including at least one sensor and at least one bypass element with a dilatant material arranged in the area of the sensor, impact forces acting upon the sensor capable of being dissipated via the dilatant material of the bypass element wherein the dilatant material runs on a top of the sensor and along two sides of the sensor and extends on the two sides fully between the screw nut and the washer. 2. The anchor bolt as recited in claim 1 wherein the sensor is embedded in the dilatant material. 3. The anchor bolt as recited in claim 1 wherein the sensor together with the washer defines a direct tension indicator. 4. The anchor bolt as recited in claim 1 wherein the sensor includes at least one indicator capsule. 5. The anchor bolt as recited in claim 1 wherein the dilatant material has a higher deformation resistance for forces applied over less than 0.1 seconds than for forces applied for more than 3 seconds.
