Prefabricated Large Span Steel Structure Buildings Prefab Metal Warehouse Workshop

Introduction to Steel Structure Warehouse

Detailed Explanation

1. Structural Safety

• Seismic & Wind Resistance:
  Buckling-Restrained Braces (BRBs) and flexible frames dissipate seismic energy; wind tunnel tests validate load distribution.
• Dynamic Load Design:
  Simulate crane loads (e.g., 50t overhead cranes) and stacking loads per GB 50009-2012, ensuring joint fatigue life≥50 years.
• Fire & Corrosion Protection:
  Apply intumescent coatings (fire resistance≥2h) and hot-dip galvanizing + epoxy coatings for harsh environments.

2. Material Selection

• Main Steel:
  Q355B steel (tensile strength 470-630MPa) for primary structures; cold-formed steel (1.5-3mm thickness) for lightweight needs.
• Envelope System:
  Polyurethane panels (thermal conductivity≤0.024W/m·K) with rock wool insulation (density≥100kg/m³).
• Eco-Materials:
  Recycled steel (recovery rate≥30%) and solvent-free epoxy flooring (VOC≤50g/L) reduce carbon footprint.

3. Prefab Component Design

• Large-Span Modularization:
  40m-span trusses or space frames maximize storage space (clear height≥10m).
• Standardized Joints:
  Predefined joint catalogs (e.g., rigid beam-column connections) cut welding time by 25%.
• Transportation & Assembly:
  Segments≤15m with temporary bracing; on-site assembly error≤3mm.

4. Energy Efficiency

• Passive Design:
  Skylights (≥20% coverage) and smart louvers reduce HVAC energy use by 40%.
• Renewable Energy:
  Monocrystalline PV panels (≥300kW·h/day) and ground-source heat pumps cover 30%+ energy demand.
• Resource Recycling:
  Bolted connections and precast foundations enable 95%+ material recovery at end-of-life.

5. Construction Quality Control

• Factory Prefabrication:
  Laser cutting (±1mm) and robotic welding (99%合格率) ensure component consistency.
• On-Site Management:
  BIM + 3D scanning monitors installation; column verticality≤H/1000, beam水平度≤L/1500.
• Acceptance Standards:
  Per GB 50205-2020:
  • Welds: UT≥40%, MT full coverage;
  • Bolts: 100% torque inspection, preload error≤±10%.
