Product Introduction
Description:
Superior High-Damping Seismic Isolators
Developed by China Communications First Highway Survey, Design, and Research Institute Co., Ltd., our high damping seismic isolators are crafted to meet the highest standards. Conforming to national standards (GB 20688) and augmented by European norms, these exceptional components are patented achievements of significant scientific research projects at provincial and ministerial levels. These isolators have received authoritative approval and certifications, notably passing the prestigious Shaanxi Science and Technology appraisal (Shaan Ke Jian Zi [2010] No. 097). Further solidifying their reputation, they adhere to the transportation industry standards of the People's Republic of China (JT 2009-26). Perfect for highways and municipal bridges within seismic zones of up to 9 degrees, these isolators offer unparalleled performance and reliability.
Our isolation rubber bearings merge the robustness of plate bearings with outstanding isolation capabilities, significantly mitigating earthquake-induced damage to bridges. High damping rubber bearings, crafted from premium high damping rubber materials, boast a remarkable damping ratio of 10% to 16%. While maintaining the structural integrity of natural rubber bearings, these advanced bearings offer superior energy absorption and ductility. By extending the natural vibration period during seismic events and leveraging their innate energy dissipation properties, they provide exceptional seismic isolation, akin to the performance of lead core sandwich rubber bearings.
Utilizing cutting-edge high damping composite rubber material instead of lead cores, these bearings allow for precise adjustment of filling material proportions to optimize damping. This innovation endows the bearings with formidable energy dissipation capabilities, effectively reducing isolation and ensuring stable performance. Their enhanced ductility and higher equivalent viscous damping lead to significant seismic isolation effects, expertly controlling seismic responses. Moreover, the integrated design results in a more compact form factor compared to lead core bearings, conserving space, simplifying construction, and offering a cost-effective alternative without compromising on quality.
