Abstract
Overvåkningsinnretningen for byggeelementer, særlig for strekkledd for Jord- og fjellankre, trykkledd for peler, spennledd for spennbetongbygg og brokabler har minst en Innvendig eller utenpå byggeelementet (1) anordnet følerkanal (15) til opptagelse av minst en føler (16) der føleren (16) er bevegelig og/eller løsbart anordnet i følerkanalen (15). En behandlings- anordning (18) påviser på grunnlag av det minst ene følerslgnal om det foreligger korrosjon, riss, lastoverskridelser, for store forlengelser og spenn- ingsavlastninger.
