MONITORING DEVICE FOR COMPONENTS, ESPECIALLY FOR TIE LINKS OF EARTH OR ROCK ANCHORS, PILE PRESSURE LINKS, TENSION LINES FOR TENSILE CONCRETE CONSTRUCTIONS AND BRIDGE ROPES

摘要

The monitoring device for structural elements, in particular for tension members in earth or rock anchors, compression members of piles, tendons for prestressed concrete structures and bridge cables has at least one sensor channel (15), arranged inside or outside a structural member (1) for accommodating at least one sensor (16). The sensor (16) is arranged movably and/or detachably in the sensor channel (15). The presence of corrosion, cracks, excessive loads, overelongations and ageing relaxation is determined by an evaluation device (18) from the at least one sensor signal. IMAGE
