Elastic Sliding Bearing (ESB)

The elastic skateboard isolation technology is to set up a skateboard isolation layer in the building to improve the seismic safety of the building. It is a kind of foundation isolation. The skateboard device is the key element in the skateboard isolation technology. The building elastic skateboard bearing is a skateboard device that can be produced in a standardized manner, which can be used for the shock isolation layer of the skateboard, and can also be used in combination with the rubber shock isolation bearing.

The building elastic sliding plate bearing is a vertical bearing member with a friction pair composed of mirror stainless steel plate and PTFE. When the horizontal force is greater than the friction force, the upper structure and the foundation will slide relative to each other to ensure the safety of the upper structure.
