During the construction process, the prestress of the steel structure needs to be tested. After the construction is completed, the stress of the steel structure will change with the increase of service life. Therefore, the prestress of the steel structure also needs to be tested regularly.

They are not practical and cannot monitor the entire change process of the steel structure after it is subjected to pressure. Utility Model Content

A force-bearing plate is installed on the other side of the movable block. A spring is provided on one side of the force-bearing plate. The two ends of the spring are fixedly connected to the two groups of force-bearing plates respectively. Detection sensors are provided on the inner sides of the two groups of detection plates.
