Tongyi brand cable tray, air duct, and pipeline seismic braces are products of Guangdong Tongyi Electric Co., Ltd. They effectively enhance the seismic resistance of corresponding electromechanical pipeline systems, ensuring the safety of building electromechanical systems during earthquakes. The following are detailed introductions:

• Cable Tray Seismic Brace

• Performance Characteristics: Made of high-strength steel such as Q235B, Q355B, or aluminum alloy, paired with hinged seismic joints, they can withstand seismic loads with horizontal acceleration ≥0.6g, absorb seismic energy, and reduce cable tray displacement. A single brace supports 50-500kg, utilizing a triangular stable structure with strong anti-overturning capability. Compatible with various specifications of cable trays, such as trough-type, and suitable for multiple building scenarios and wall structures. The surface is treated with hot-dip galvanization, ensuring an outdoor service life of over 20 years.

• Structural Design: Provides seismic support in longitudinal, transverse, and vertical directions. Standardized accessories allow for quick on-site assembly without welding, with easy adjustments later. The material is non-combustible and can share a base with other electromechanical seismic braces.

• Applicable Scenarios and Standards: Suitable for regions with seismic fortification intensity ≥6 degrees, especially in buildings like hospitals and schools. The spacing for horizontal cable tray seismic braces is ≤18m (fortification intensity 6-7 degrees) or ≤12m (fortification intensity 8-9 degrees), while vertical cable tray spacing is ≤4m, with at least one brace per floor.

• Air Duct Seismic Brace

• Performance Characteristics: By restricting air duct displacement and controlling vibration, it reduces the risk of air duct detachment and fracture during earthquakes, ensuring the normal operation of ventilation and air conditioning systems post-earthquake.

• Design Standards and Specifications: According to the "Code for Seismic Design of Building Electromechanical Engineering" (GB 50981), air ducts with a diameter ≥80mm in regions with seismic fortification intensity ≥6 degrees require seismic braces. The spacing and seismic load capacity of the braces must be calculated based on the building's seismic fortification category, air duct material, pipe diameter, and other parameters.

• Main Components: Consists of anchors, seismic connection components, load-bearing hangers, and seismic joint accessories. Anchors commonly use expansion bolts, seismic connection components are often C-shaped channel steel, load-bearing hangers comprise rods and cross beams, and joint accessories ensure secure connections between all parts.

• Material Requirements: Components are mostly made of Q235B carbon steel, with surfaces galvanized (zinc coating thickness ≥65μm) or coated with anti-corrosion paint.

• Application Scenarios: Widely used in public buildings such as hospitals, shopping malls, and subways, as well as in ventilation, air conditioning, and smoke control systems of high-rise residential buildings.

• Pipeline Seismic Brace

• Performance Characteristics: Effectively restricts pipeline displacement during earthquakes, controls facility vibration, alters the dynamic characteristics of the pipeline system, significantly reducing response under seismic action and minimizing the risk of pipeline fracture and detachment.

• Structural Composition: Typically consists of anchors, reinforced hangers, seismic connection components, and seismic diagonal braces, securely connecting the pipeline to the building structure to form a complete force-bearing system.

• Materials and Corrosion Protection: Primarily made of carbon steel (e.g., Q235B/Q345), with surfaces treated with hot-dip galvanization or epoxy coating. Galvanized steel materials are hard, deformation-resistant, and highly durable.

• Installation Features: Composed of modular components for assembled construction, requiring no welding or drilling, enabling fast installation. A wide variety of standard components ensures good versatility and combinability, allowing shared use with other professional support hangers.

• Application Range: Suitable for building water supply, drainage, fire protection, and other pipeline systems in various construction projects, including residential, commercial plazas, and industrial plants.
