Double-hanging unidirectional support is a key component in building mechanical and electrical seismic support systems, offering a simplified yet efficient combination of lateral and longitudinal protection. Comprising two suspension rods ("double hanging") and a unidirectional seismic diagonal brace assembly, this support provides vertical load-bearing via the rods and horizontal seismic restraint perpendicular to the rod axis. product strikes a balance between basic seismic compliance, structural simplicity, and cost-effectiveness, making it ideal for linear pipeline installations with limited space, uniform loads, and the need to resist single-direction seismic forces.
The core strength of Double-hanging unidirectional support lies in its "dual rods + unidirectional brace" configuration. The two suspension rods, mounted on either side or two points of the pipeline, ensure stable vertical suspension and anchor securely to the structural ceiling via seismic connectors. The accompanying unidirectional diagonal brace-typically a rigid steel brace with articulation-forms a stable triangular structure at a 45-degree angle, efficiently transferring single-direction horizontal seismic forces to the building's main structure. Designed in accordance with GB 50981, product undergoes rigorous mechanical calculations to ensure the brace, connectors, and anchors withstand specified seismic loads, with clear marking of seismic direction during installation.
Double-hanging unidirectional support excels in seismic reinforcement of long straight sections of air ducts, water pipes, or multi-row cable trays, particularly in areas with limited ceiling height where complex bidirectional portal supports are unfeasible. It is perfect for auxiliary pipelines like general ventilation and air conditioning pipes, as well as lightweight pipelines with uniform cross-sections. Offering cost savings through minimal materials, easy standardized assembly, and space-efficient design, product provides reliable, targeted seismic protection while facilitating convenient pipeline inspection and maintenance-making it a widely used foundational unit in seismic support systems.
