点击放大Cable Tray Lateral Seismic Brace (T)
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 anchoring components, reinforced hanger rods, seismic connection components, and seismic diagonal braces. Product Overview: The cable tray lateral seismic brace is a lateral seismic support specifically designed for electrical cable facilities such as cable trays, cable ladder racks, cable troughs, and busways. The diagonal brace is arranged parallel to the cross-section of the tray to resist lateral horizontal seismic forces. Structural Composition: Comprised of anchoring components, reinforced hanger rods, seismic connection components, and seismic diagonal braces. The inner edges of the U-shaped channel steel must feature serrations with a tooth depth of no less than 0.9mm, and all accessory installations are achieved through mechanical interlocking. The surface of the bracket channel steel is treated with hot-dip galvanizing (zinc layer thickness no less than 60μm) to meet durability requirements. Spacing: ≤12m (lateral spacing) Core Function: To limit the lateral displacement of cable trays during earthquakes, control tray vibration, and transfer loads to the load-bearing structure. This prevents tray detachment and cable rupture, ensuring the normal operation of power supply and fire protection systems. Applicable Areas: New construction, renovation, and expansion projects in regions with seismic fortification intensity of 6 to 9 degrees. Application Scenarios: Electrical conduits with an inner diameter ≥60mm; cable ladder racks, cable troughs, and busways with a gravity load ≥150N/m; regions with seismic fortification intensity of 6 degrees or above; widely used in major national construction projects such as nuclear power plants, power plant renovations, high-speed railway construction, and airport expansions. For tray bottom widths ≤600mm, single-sided bracing is used; for tray bottom widths ≥800mm, double-sided bracing is used; longitudinal bracing is double-supported in all cases.
