One end of the steel wire rope is fixed through the locking assembly 12, and the other end is connected to the tensioning jack 51 through the clamp 222. The hydraulic station 52 inputs hydraulic oil to the tensioning jack 51 through the oil inlet pipe 53. Convert the preliminary strength value of the steel structure frame 3 into the output pressure of the hydraulic station 52. After the tensioning jack 51 completes the tensioning, let it stand for a moment, and then unload the load through the oil return pipe 54. Observe and measure the deformation degree of the steel structure frame 3, so as to complete the strength detection of the steel structure frame 3. By setting the output pressure multiple times, the strength of the steel structure frame 3 is checked in turn.
