[0026] Beneficial Effects

[0027] The present invention provides a testing method for the compressive strength of a building steel-concrete structure. Compared with the prior art, it has the following beneficial effects:

[0028] (1) By setting up a pressure-vibration mechanism, the surface of the prefabricated board can be subjected to a gradual compression test by pressing down and rolling the roller. At the same time, the resistance bar moves synchronously with the roller, and the prefabricated board can be subjected to a synchronous vibration test, thereby improving the diversity of the device testing methods.

[0029] (2) By setting up a driving component, the friction contact between the roller and the inner wall of the drum is utilized to follow the synchronous rotation when the drum rolls, and the transmission is carried out through the engagement of the worm gear and the worm, thereby driving the ball screw to follow the rotation, so that the bar follows the synchronous movement, causing the drum to vibrate, so as to carry out vibration resistance test on the precast panel.

[0030] (3) By setting up a transmission unit, the transmission rod utilizes two oppositely arranged ratchet wheels and drives a single rotating gear through two transmission gears, so that the ball screw is always driven in a single direction regardless of the forward or reverse rotation of the roller, so as to improve the stability of the movement of the bar.

[0031] (4) By setting up a vibration reduction assembly and utilizing the connection of a spring rod, a clamping ring and a fixed ring, the roller and the push frame are radially movable and connected, and the vibration of the roller is buffered through the elastic force, thereby reducing the force on the push frame, thereby avoiding damage to the lifting rod and the linear motor.

[0032] (5) By setting up an adjustment component and utilizing the magnetic repulsion between the magnetic plate and the electromagnets on both sides, the magnetic plate can drive the cone to move up and down through the sliding sleeve to adapt to prefabricated panels of different specifications. At the same time, the sliding sleeve and the center of the fixed frame are connected by sliding. When subjected to longitudinal pressure and vibration, the cone can achieve its own buffering through up and down movement and magnetic damping to avoid damage due to force.
