This invention proposes a novel steel structure seismic-resistant block, fixedly installed at the bottom of a steel box girder and on the inner side of the pier support. It includes a damping plate and a stiffening plate. The damping plate is fixedly mounted on a fixed frame composed of stiffening plates, facing the pier support. The fixed frame is fixedly mounted at the bottom of the steel box girder. The damping plate includes a plate bearing and evenly distributed nails on the plate bearing. Both the plate bearing and the nails are made of neoprene rubber. This invention achieves its damping function by using a neoprene rubber damping plate instead of the original elastic structure. It serves as a primary energy-dissipating structure, with a stiffening plate behind the damping plate acting as a secondary energy-dissipating structure. This multi-layered energy-dissipating structure results in better overall damping performance, effectively absorbing and attenuating vibrations, and reducing the impact of lateral slippage of the superstructure on the pier.

The utility model relates to the field of draw-bar box, disclose a shock absorbing gyro wheel and utilize the draw-bar box of gyro wheel. The shock absorbing gyro wheel, including several mounting frames, several mounting frames are arranged on several gyro body respectively, the top of several mounting frames all is equipped with L shaped board, the inside of several L shaped boards all are connected with the shaft through bearing, the top surface of several movable plates all are fixed with first spring, the threaded end of several screw rods all are connected with nut threadedly. In the utility model, through the cooperation of mounting frame, gyro body, L shaped board, shaft, mounting frame, movable plate, fixed plate, movable cylinder, screw rod, first spring and nut, the problem that the gyro body of traditional draw-bar box is poor in shock resistance can be solved, the stable and reliable shock absorbing effect is provided, the first spring design of adjustable can adapt to the requirement of shock absorbing effect under different weight, different road conditions, improve the applicability and practicality of the shock absorbing gyro wheel.

A vibration-controlled elastic bearing with steel spring laminated rubber sheet is provided, comprising an upper connecting plate, a lower connecting plate, and a damping body. Multiple vertically arranged damping springs for absorbing vibration energy are evenly distributed inside the damping body. The upper and lower ends of the damping springs, which penetrate the damping body, are respectively connected to the upper and lower connecting plates via an upper sealing plate located above the damping body and a lower sealing plate located on the lower end face of the damping body. This invention optimizes the internal structure of the elastic bearing to achieve dual vibration control, ensuring reliable damping while improving the load-bearing capacity for large shear forces. It solves the pollution problem associated with traditional core rubber seismic isolation bearings. While the damping springs bear the main dynamic load, it reduces fatigue damage to the damping body, lowers its aging rate, and extends its service life.
