ANCHOR AXIAL FORCE METER CAPABLE OF EXCHANGING ONLY SENSOR IN SERVICE AND ITS SENSOR EXCHANGING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an anchor axial force meter capable of easily exchanging only sensor in service without releasing tension force of the anchor and without exchanging the main body (called straining body or the like) of the axial force meter and its sensor exchanging method. SOLUTION: A bearing plate 6, a straining body 7 and an axial force meter receiving plate are arranged in between a fixing tool 5 and a stage 16 in a head cap, a tendon 4 is arranged on their center line and the straining body 7 fixes a sensor 8 with a sensor body fixing bolt 21. By rotating a strain transmission rod with a rotation screw in a fixing screw 20 prepared in the straining body 7 in the structure, adjustment is performed and it is fixed with a fixing nut.
