Historically, domestic electromechanical facilities focused on load-bearing capacity often overlooked earthquake-resistant design, posing significant safety risks. The Code for Seismic Design of Mechanical and Electrical Systems in Buildings formalized seismic support systems as essential safeguards. By integrating load mechanics and seismic action calculations, these systems anchor pipelines, ducts, cable trays, and equipment to pre-reinforced building structures. This method minimizes displacement, controls vibrations, and transfers seismic forces to load-bearing components, prioritizing life safety and reducing earthquake-induced damage. Known as Seismic Support and Hanger systems, they are now a cornerstone of industrial and large-scale construction projects.
These systems balance flexibility and rigidity through advanced engineering:
1. Vibration Absorption
Elastic Components: Parts like the Channel Nut With Plastic Holder absorb seismic energy, isolating pipelines from direct shockwaves.
Energy Dissipation: Flexible materials reduce resonance effects, preventing structural fatigue.
2. Structural Reinforcement
High-Strength Fasteners: Components such as V-Shaped Stiffener Rods, Hexagonal Coupling Nuts, and Thread Rods enhance rigidity, resisting deformation during seismic events.
Anti-Slip Design: Textured surfaces and locking mechanisms prevent equipment slippage.
3. Multi-Directional Constraints
Adjustable Brackets: Provide horizontal, vertical, and diagonal support to stabilize equipment under complex forces.
Load Distribution: Redirect seismic energy across multiple anchor points, avoiding localized stress failures.
Mandated by China’s Building Law and Earthquake Disaster Prevention Law, seismic systems protect vital infrastructure:
1. High-Rise Buildings
Secure HVAC ducts, electrical conduits, and fire suppression pipelines, ensuring functionality post-earthquake.
Example: Hospitals and data centers rely on these systems to maintain critical operations during disasters.
2. Industrial Complexes
Petrochemical plants, power stations, and nuclear facilities use seismic supports to prevent leaks, explosions, and production halts.
Case Study: A refinery in seismic Zone 7 reduced downtime by 40% after retrofitting with seismic hangers.
3. Transportation Networks
Reinforce bridges, tunnels, and rail systems to withstand ground motion, ensuring evacuation routes remain intact.
4. Public Spaces
Theaters, stadiums, and airports integrate seismic systems to protect overhead installations like lighting and signage.
1. Material Durability
Opt for galvanized carbon steel or stainless steel to combat corrosion and extend service life.
Avoid low-cost alloys that may degrade in humid or chemical environments.
2. Compliance Standards
Ensure products meet GB/T 37267-2018 (China’s seismic code) and international certifications like ISO 16134.
3. Customization Needs
Choose suppliers offering tailored solutions for irregular layouts or heavy-duty equipment.
