Background
The vibration-reducing and isolating support is a common support component in the fields of bridges and buildings, and has the dual functions of vibration isolation and energy consumption. The vibration reduction and isolation support realizes a vibration isolation function by utilizing a simple pendulum, and consumes energy by utilizing mutual friction of contact surfaces. The earthquake motion is a vibration process of continuous attenuation, and when the earthquake energy is continuously attenuated, the support and related structures gradually change from a state of mainly forced vibration to a state of mainly free vibration. After entering a free vibration state, the vibration reduction and isolation device has a certain self-resetting function and can reset to an initial balance position, but due to the existence of friction force, the support cannot realize a complete reset function after the vibration.

And a limit shear plate which is sheared after earthquake is fixed on two sides of the transverse bridge direction or/and the longitudinal bridge direction of the lower seat plate, the inner side surface of the limit shear plate is arranged corresponding to the outer side surface of the upper seat plate, and a guide friction pair is arranged between the inner side surface of the limit shear plate and the outer side surface of the upper seat plate.
The invention has the beneficial effects that: the lower surface of the locking element is clamped in the groove of the lower seat plate to form a locking reset structure.

Since the locking element 8 has a pre-pressure, the lower seat plate 10 must provide a sufficient starting external force to lift and press the locking element 8 into the middle seat plate to enable the lower spherical friction pair to slide relatively, so that the friction force of the lower spherical friction pair and the locking force of the locking element 8 and the lower seat plate 10 must be overcome by the relative movement between the middle seat plate 4 and the lower seat plate 10 under the earthquake working condition.
