Introduction
Core Technology and Innovation Points
| Technical Indicators | 2005 Edition | 20XX Revised Edition |
|---|---|---|
| Fireproof Material Performance | Only basic requirements are specified | Clear A-grade material standards (GB 8624) |
| Wall Column Spacing | 405/610mm | Newly added 450mm to adapt to 900mm panels |
| Seismic Design | Unspecified calculation formula | Newly added formulas (5.1.3)-(5.1.5) |
Key parameters of material performance
Comparison of sound insulation of gypsum board
| Thickness (mm) | Surface density (kg/m²) | 125Hz | 500Hz | 2000Hz |
|---|---|---|---|---|
| 9.5 | 9.5 | 11dB | 22dB | 27dB |
| 15.0 | 15.0 | 16dB | 28dB | 32dB |
Rock wool filling density requirements: household wall ≥28kg/m³, exterior wall ≥40kg/m³
Typical structural nodes
- Right-angle connection nodes: Use L50×50×4 angle steel for protection, screw spacing ≤750mm
- Electrical box installation: The sound insulation wall needs to be filled with Rock wool +10mm gypsum sealing layer on both sides
- Suspension system: Loads above 300N require φ6mm self-tapping screws, with a penetration depth of ≥30mm
Implementation suggestions
Special measures for severe cold regions
- Add vapor barrier (≥0.2mm plastic film)
- Use double-row wooden frame + double-layer paper-faced gypsum board
- The air layer is set on the low-temperature side
Red line indicators for quality acceptance
- Flatness deviation ≤3mm/2m
- Vertical deviation ≤3mm/2m
- Continuous fullness of fireproof sealant 100%
