MONITORING DEVICE FOR STRUCTURAL ELEMENTS, IN PARTICULAR FOR TENSION MEMBERS OF SOIL OR ROCK ANCHORS, COMPRESSION MEMBERS OF POLES, PRESTRESSINGELEMENTS FOR PRESTRESSED CONCRETE STRUCTURES AND BRIDGE CABLES

摘要

The monitoring device for structural elements, in particular for tension members of soil or rock anchors, compression members of poles, prestressing elements for prestressed concrete structures and bridge cables has at least one sensor conduit (15) disposed inside or outside of a structural element (1) for receiving at least one sensor (16), wherein the sensor (16) is disposed movably and/or releasably in the sensor conduit (15). An evaluation device (18) determines the presence of corrosion, cracks, overloads, overextensions and tension relaxation from the at least one sensor signal.
