Building isolation rubber bearings (LRB/LNR)

Building isolation rubber bearings are composed of alternating overlapping combinations of multi-layer rubber and multi-layer steel plates or other materials. According to the requirements of different buildings, isolation rubber bearings can have different laminated structures, manufacturing processes, and formula designs to meet the required performance requirements such as vertical stiffness, lateral deformation, damping, durability, and ensure a service life of no less than 60 years.
Rubber isolation technology is safer, more reliable, and more economical than traditional seismic technology. Isolation technology plays a role of "isolation" through isolation, separating the upper structure from the lower foundation, reducing the stiffness of the isolation layer, effectively reducing seismic response by 70-90%, equivalent to reducing seismic intensity by 1-2 degrees, and saving engineering costs by 5-20%. In addition to new construction projects, it is also widely used for the improvement and reinforcement of old buildings, which is considered a significant leap in seismic technology.
