Structural design requires special attention to five aspects: structural stability, sound insulation layer design, sealing and closure design, movable and disassembly mechanisms, and fire protection and safety design. These design aspects directly impact the sound insulation performance, service life, and safety of the partition. The following is a detailed analysis:
I. Structural Stability: Ensure the partition maintains deformation over time.
Frame Material and Connection Method
Material Selection: Prefer high-strength aluminum alloys (such as 6063-T5 or 7075-T6) or steel frames to ensure structural load-bearing capacity.
Connection Method: Use mortise and tenon joints, welding, or high-strength bolts to prevent loosening or deformation. For example, aluminum alloy frames can be seamlessly joined through precision extrusion, minimizing gaps and sound leakage.
Tips to Avoid: Avoid using low-strength materials or simple connection methods, as these may cause deformation and compromise sound insulation over time.
Impact Resistance and Durability Design
Reinforcement Ribs: Add horizontal or vertical reinforcement ribs to the frame to enhance overall impact resistance. Surface Treatment: Anodizing, spray coating, or electrophoretic coating enhances corrosion resistance and extends service life.
Tips for Avoiding Pitfalls: Check the diagonal deviation of the partitions (should be within 0.5-1.5mm) to ensure structural stability and avoid deformation due to installation errors.
II. Sound Insulation Design: Multi-layered Sound Blocking
Double-layer/Multi-layer Structure
Design Principle: Two or more layers of sound insulation materials (such as sound insulation panels or sound insulation felt) create an air barrier, utilizing the damping effect of air to reduce sound transmission.
Recommended Combinations:
Outer Layer: High-density fiberboard (HDF) or steel plate to block high-frequency noise.
Middle Layer: Sound insulation felt or fiberglass wool to absorb mid- and low-frequency noise.
Inner Layer: Perforated gypsum board or sound-absorbing panels to further dissipate sound waves.
Tips for Avoiding Pitfalls: Avoid single-layer, thin panel designs, as these will limit sound insulation effectiveness.
Cavity Filling with Sound-Absorbing Materials
Cavity Width: Increase the width of the wall cavity (recommended ≥50mm) to create an air gap that reduces sound transmission efficiency.
Filling Material: Use glass fiber or mineral wool with a density ≥32kg/m³. Avoid using ordinary sponge (which ages easily and has poor sound insulation).
Tip: Check that the filling material is evenly distributed to avoid gaps that could cause sound insulation holes.
III. Sealing and Closure Design: Comprehensively Prevent Sound Waves from Leaking
Frame Sealing Strips
Material: EPDM rubber strips offer long life, excellent elasticity, and adaptability to temperature fluctuations without deformation.
Installation Method: The sealing strips must be inserted into the frame grooves to ensure a tight fit against the wall, avoiding gaps.
Tip: Avoid using ordinary rubber strips, as they are prone to aging and cracking, resulting in seal failure.
Automatic Bottom Seal Strips
Design Principle: When the partition is closed, the bottom seal strip automatically descends to fill the gap in the floor, creating a complete seal.
Recommended Mechanism: Use a pneumatic or electric lift system to ensure smooth seal raising and lowering and a tight seal. Tips for Avoiding Pitfalls: Check the seal material for wear resistance and moisture resistance to prevent deformation after long-term use.
Joint and Hole Treatment
Joint Sealing: Use specialized sound-isolating sealant to seal all joints and ensure no sound leaks.
Hole Treatment: Seal holes for wires and fasteners to prevent sound transmission through small holes.
Pitfall Avoidance Tips: Avoid relying solely on soundproofing materials without ignoring structural airtightness, as this will significantly reduce the sound insulation effect.
IV. Movable and Disassembly Mechanism: Balance flexibility and sound insulation.
Track and Horizontal Wheel Design
Track Material: Choose high-strength aluminum alloy or steel tracks to ensure load-bearing capacity.
Horizontal Wheel Selection: Use dual-bearing silent wheels to reduce push and pull noise while ensuring smooth operation.
Pitfall Avoidance Tips: Avoid rust or deformation on the track surface, as this can make pushing and pulling difficult.
Modular Assembly and Disassembly Design
Quick Connection: Use snap-on or bolt-on connections for quick assembly and disassembly and layout adjustment. Positioning System: Positioning blocks are installed on the track or floor to ensure precise alignment when the partition is closed, improving the seal.
Tips for Avoiding Pitfalls: Check that the assembly and disassembly mechanisms are secure to prevent loosening after prolonged use.
V. Fire Prevention and Safety Design: Comply with Regulations to Ensure Safety
Fire Rating
Material Requirements: Use Class A non-combustible materials (such as steel plates or gypsum boards) or Class B1 flame-retardant materials (such as flame-retardant fiberboard).
Filling Materials: Internal fillings of fiberglass or mineral wool must meet fire protection standards; avoid using flammable materials.
Tips for Avoiding Pitfalls: Check the product's fire safety test report to ensure compliance with national regulations.
Safety Protection Design
Anti-Pinch Design: Soft protective strips are installed on the edges of the partition to prevent fingers from being pinched when pushing or pulling.
Stabilization Devices: Anti-tilt devices are added to high-rise or large partitions to ensure safe use.
Tips for Avoiding Pitfalls: Avoid overlooking safety details, as this may lead to safety hazards.
