Cable Tray Side Longitudinal Seismic Bracing (T+L)

Seismic Bracing is a seismic support facility that is firmly connected to the building structure, with seismic force as the primary load. Its core function is to restrain the horizontal displacement of mechanical and electrical pipelines and equipment during an earthquake, preventing pipe detachment, collision, and rupture, thereby ensuring the functional continuity of lifeline systems. Definition (GB/T 37267-2018): A seismic support facility firmly connected to the building structure, consisting of anchor components, reinforced hanger rods, seismic connection components, and seismic diagonal braces. Product Overview: The lateral-longitudinal seismic support for ventilation ducts is a pipe support that incorporates both lateral and longitudinal seismic diagonal braces on the basis of the ventilation duct seismic bracing system, also known as a bidirectional seismic support for air ducts. It is suitable for duct systems requiring comprehensive seismic protection. Structural Composition: Includes two sets of seismic diagonal braces—lateral and longitudinal. Made of Q235B carbon structural steel, compliant with GB50981-2014 and CJ/T476-2015 standards. Connected with bolts without the need for welding, and can be installed using common tools for simple and convenient operation, accelerating construction progress, reducing installation costs, and requiring no post-installation maintenance. Certified by the National Building Materials Testing Center. Spacing Requirements: ≤9m (lateral spacing) ≤18m (longitudinal spacing). Core Function: Provides comprehensive resistance to horizontal seismic forces in both lateral and longitudinal directions. When the duct is subjected to lateral seismic forces, the diagonal braces provide lateral support to the duct, reducing the likelihood of swaying, and work in conjunction with the vertical members to effectively enhance stability, preventing the duct from falling during vibration. This ensures all-around safety of the duct system during an earthquake. Applicable Regions: New construction, renovation, and expansion projects in areas with seismic fortification intensity of 6 to 9 degrees. Application Scenarios: Rectangular ducts with a cross-sectional area ≥0.38㎡; circular ducts with a diameter ≥0.70m; pipes in boiler rooms, refrigeration machine rooms, and heat exchange stations; ventilation and air conditioning systems in important public buildings. Smoke exhaust ducts, emergency ventilation ducts, and related equipment.
