Abstract

En anordning 92 for overvåking av påkjenningen av en skjøt i en byggestmktur, hvilken omfatter en kappeanordning 52 i form av et første og et andre kappeelement 62, som hver består av en primær kappedel 62a og en ortogonal sekundær kappedel 62b. Kappeelementene 62 danner til sammen et rom for å motta skjøten mellom to rør 54, 56 som skal overvåkes. Kappeanordningen 52 omfatter i tillegg to primære finneelementer 76, 78 plassert mellom de primære og sekundære kappedelene 62a, 62b. Tre fiber-Bragggitter(FBG)-påkjenningssensorer 96, 98, 100 og én FBG-temperatursensor 102 ligger i en optisk fiber 104, forbundet til de primære finneelementene 76, 78 og til hver ende av det andre kappeelementet 62, for å måle påkjenningen og temperaturen på de respektive målepunktene. FBG-sensorene 96, 98, 100, 102 er optisk koblet, ved hjelp av optisk fiber 104, til en anordning for avlesing av fiberoptiske sensorer som kan avlese hver FBG-sensor.
