Rubber seismic isolation and reduction device winded with carbon fiber cloth externally
The invention provides a rubber seismic isolation and reduction device winded with carbon fiber cloth externally and belongs to the field of seismic isolation and reduction of bridges. The problem that a traditional seismic isolation and reduction device is high in manufacturing cost and poor in seismic isolation and reduction performance, is easily damaged, is not easy to replace and the like is solved. The rubber seismic isolation and reduction device is simple in design principle, and the high-strength carbon fiber cloth is winded on an elastic rubber cylinder to improve the overall rigidity, so that the situation that traditional seismic isolation and reduction stop blocks excessively deform when bearing seismic force and accordingly are pressed to be damaged is avoided. The rubber seismic isolation and reduction device can be specifically designed according to seismic forces borne by the bridges, and devices matched with different types of bridges and meeting different seismic force demands are designed by changing the size of the cylinder and a carbon fiber cloth winding mode. Due to the fact that the rubber seismic isolation and reduction device is simple in structure, only a longitudinal or transverse stop block is arranged at the bridge pier top and a box bridge position respectively according to the design demand, and the device is arranged between the two stop blocks and is very convenient to install and replace.
