Product Description

Product Description

Seismic isolation bearing is a revolutionary building structure seismic device that effectively isolates and attenuates the upward transmission of seismic wave energy by flexibly connecting the superstructure with the foundation. This advanced seismic isolation bearing product adopts a multi-layer composite structure design, with a core composed of alternately laminated high-performance rubber and steel plates, forming an intelligent bearing system with vertical load-bearing, horizontal flexibility, and automatic reset functions. Seismic isolation bearing can provide sufficient vertical stiffness to support building weight during normal use, while through large horizontal deformation during earthquakes, it can extend the structural period and dissipate seismic energy, thereby reducing the seismic force transmitted to the superstructure to a fraction of that of traditional seismic structures, ensuring life safety of building occupants and functional integrity of important equipment.

As a highly specialized engineering shock absorption product, seismic isolation bearing follows the most stringent quality standards in both R&D design and production manufacturing. Modern seismic isolation bearings adopt blended formulas of premium natural and synthetic rubber, built-in multi-layer high-strength steel skeletons and special damping materials, integrally formed through precision vulcanization processes. The horizontal stiffness and equivalent damping ratio of seismic isolation bearing undergo rigorous calculation and testing verification to ensure optimal isolation effects under different intensity earthquakes. This bearing does not require changes to traditional structural forms in building design and can be flexibly applied to both new construction projects and seismic retrofitting of existing buildings.

Product Types and Introduction
    *Natural Rubber Seismic Isolation Bearing: Uses natural rubber as main material, with stable vertical load-bearing capacity and strong horizontal deformation ability, being the most commonly used seismic isolation bearing type for most civil buildings.
    *Lead Rubber Seismic Isolation Bearing: Features built-in lead core providing additional damping, with stronger energy dissipation capacity, the seismic isolation bearing can effectively control seismic displacement, suitable for high-rise buildings.
    *High Damping Rubber Seismic Isolation Bearing: Adopts high-damping formula rubber achieving excellent energy dissipation effect without lead core, the seismic isolation bearing has better environmental performance.
    *Friction Pendulum Seismic Isolation Bearing: Dissipates energy through spherical sliding friction, the seismic isolation bearing features self-centering function, suitable for bridges and buildings with large displacement requirements.
