Steel arch strainometer fixing device

A steel arch strainometer fixing device comprises a columnar strainometer and mounting supports. The mounting supports are mounted at two ends of the columnar strainometer respectively, each mounting support consists of a mounting portion and a fixing portion, each fixing portion is provided with a preformed mounting hole used for clamping the column strainometer, each mounting portion is in a right-angular structure consisting of a vertical part and a horizontal part, the mounting portions and the fixing portions form an integral structure through the vertical parts of the mounting portions, and a clamping groove used for containing a steel arch is formed between the horizontal part of each mounting portion and the corresponding fixing portion. The steel arch strainometer fixing device is simple in structure, reasonable in design and convenient to operate, the columnar strainometer can be stably and reliably fixed onto the steel arch and protected from being damaged by electric welding, and mounting efficiency and mounting success rate of the columnar strainometer are greatly improved. In addition, the steel arch strainometer is integrally convenient to assemble, low in cost and high in practicality.
