STRAIN MEASUREMENT DEVICE AND METHOD OF FIXING STRAIN MEASUREMENT ELEMENT

摘要

In a tie bar strain measuring device, even if an elongation is generated in a belt for attachment, a strain gauge can be pressed against a tie bar continuously with a sufficient pressing force by absorbing the elongation. The strain gauge is fixed to a strain gauge fixing member, and a belt-like member is wound around an outer circumference of the tie bar so as to retain the strain gauge fixing member while pressing against an outer circumferential surface of the tie bar. The belt-like member is clamped by a clamping device. A clamping force is generated by a resilient restoration force of a conical plate spring provided in the clamping device.
