Contact me to order processing of JZQZ-20000kN-ZX highway bridge friction pendulum isolation bearings

The friction pendulum isolation bearing is a seismic isolation device that combines friction sliding with pendulum reset functionality, primarily used in bridges, buildings, and other engineering projects to effectively absorb seismic energy and reduce structural vibrations. Through friction energy dissipation and the pendulum effect, this bearing provides damping and automatic reset, making it suitable for high-intensity seismic zones and large-span structures.

1. Product Features

(1) Superior Seismic Isolation Performance

• Friction Energy Dissipation: Utilizes specialized friction materials (such as PTFE and high-strength alloys) to dissipate seismic energy through sliding.
• Pendulum Reset: Employs the pendulum effect of curved sliding surfaces to automatically return to the original position after an earthquake, minimizing residual displacement.
• Multi-Directional Adaptability: Capable of withstanding horizontal bidirectional (X/Y direction) displacements, adapting to complex seismic actions.

(2) High Load-Bearing Capacity

• Vertical load-bearing capacity can reach 5000~30000kN (varies by model).
• Horizontal load-bearing capacity is adjustable to meet different seismic grade requirements.

(3) Strong Durability

• Sliding surfaces use stainless steel + PTFE composite materials, offering wear resistance and corrosion resistance.
• Sealed structural design prevents dust and moisture intrusion, extending service life.

(4) Easy Installation

• Standardized design complies with specifications such as **GB/T 20688.3 "Rubber Isolation Bearings for Buildings"**.
• Suitable for prefabrication or on-site assembly, applicable to both new construction and reinforcement projects.

2. Applicable Engineering Scope

• Highway and Railway Bridges (especially in high-intensity seismic zones)
• Large-Span Buildings (e.g., stadiums, airport terminals)
• Nuclear Power Plants, Critical Public Facilities (requiring high seismic performance)
• Seismic Reinforcement of Existing Structures
