[0002] Stress testing generally refers to the technical means of using monitoring instruments to monitor the stress changes of the stressed structure during the construction process of buildings, such as steel structure installation, unloading, modification, reinforcement, concrete pouring, etc., and issuing an alarm when the monitored value approaches the control value to ensure the safety of construction. It can also be used to check whether the construction process is reasonable.

[0003] Steel structures are used in various places, among which in-service steel refers to the steel structures in use. When the steel structures in use need to be inspected, some of the steel structures are difficult to dismantle for inspection and need to be inspected during work.

[0004] In the prior art, there is a device for detecting residual stress in welding of steel structures with application number CN202022832086.8. In the above scheme, "the magnet is adsorbed on both sides of the steel structure so that the magnet is adsorbed on the steel contact, so that the positioning plate is fixed on both sides of the steel structure, and then the suction cup is driven to move toward the steel structure by twisting the first threaded rod, so that the suction cup is adsorbed on both sides of the steel structure and fixed again." However, the existence of steel structures in some buildings is not convenient for disassembly and inspection, and it is necessary to conduct inspection during use. The above inconvenience is to install the detection probe next to the in-service steel structure to be inspected, and the stress is detected by the in-service steel structure during use.

People approaching for detection may easily cause irreversible risks to people. How to invent a positioning device for stress detection of in-service steel structures to improve these problems has become an urgent problem to be solved by those skilled in the art.
