Detailed Specifications
1. Structural Safety
- Seismic Design: Buckling-Restrained Braces (BRBs) and flexible steel frames in high-seismic zones to dissipate energy through plastic deformation
- Load Calculation: Includes crane loads (e.g., 20t overhead crane) and equipment vibration loads with dynamic analysis per GB 50009-2012
- Fire & Corrosion Protection: Thick fireproof coatings (fire resistance ≥2 hours) and hot-dip galvanizing + epoxy primer for industrial environments
2. Material Selection
- Main Steel: Q345B steel (yield strength 345MPa) for primary structures and Q235B steel for secondary components
- Envelope Materials: Polyurethane sandwich panels (thermal conductivity ≤0.022W/m*K) for walls/roof, combining insulation and fire resistance
- Connection Materials: Grade 10.9 bolts and submerged arc welding ensure joint strength and airtightness
3. Prefab Component Design
- Large-Span Optimization: Trusses (span≥30m) or portal frames minimize internal columns, maximizing usable space
- Standardized Joints: Predefined joint catalogs (e.g., end-plate connections) reduce fabrication complexity and cut 15%-20% costs
- Transportation Segmentation: Components segmented per road limits (length≤12m, width≤3m), with on-site assembly error≤5mm
4. Energy Efficiency
- Passive Design: Skylights (≥15% coverage) and sidewall louvers reduce lighting and ventilation energy use
- Active Systems: PV systems (≥200kW*h/day) and waste heat recovery achieve 30%+ energy self-sufficiency
- Resource Recycling: Recycled steel (recovery rate≥85%) and demountable foundations enable 90%+ material reuse
5. Construction Quality Control
- Factory Prefabrication: CNC cutting and robotic welding ensure component precision (tolerance±2mm)
- On-Site Management: BIM clash detection pre-installation; total station checks column verticality (deviation≤H/1000)
- Acceptance Standards: Per GB 50205-2020: 100% bolt torque inspection; ≥95% welds meet Grade II+ quality
