Introduction
Jilin Yongji Jinyu Storage Shed Grid Space Framework
Structural Form
Bolt ball joint framework (suitable for spans of 30-60m, high standardization, quick installation)
Double-layer upright four-corner cone framework (good stability, suitable for northern snow loads)
Local reinforcement design: add truss support at the storage shed entrance (for wind pressure requirements)
Snow Load: Yongji County ≥ 0.75 kN/m² (needs verification for uneven snow distribution conditions)
Wind Load: Basic wind pressure 0.55 kN/m² (considering winter monsoon effects)
Seismic: 7-degree protection (0.10g)
Corrosion Protection: Hot-dip galvanizing (≥80μm) + fire-retardant coating (fire resistance limit 1.5 hours)
Advantage Reference Case Distance by Car from Yongji
Direct supply of Q355B steel from steel mill, price advantage Tonghua Steel Storage Shed Framework 2 hours
Equipped with CNC intersecting line cutting machine FAW Logistics Warehouse 1.5 hours
Focus on large-span bolt ball frameworks Shenyang Free Trade Zone Storage Shed 3 hours
Rich experience in construction in cold regions Harbin Grain Storage 4 hours
Key Construction Processes and Schedule
A[Geological Survey] --> B[Foundation Embedded Parts Construction]
B --> C[Framework Ground Assembly]
C --> D[Segmental Hoisting (or Overall Lifting)]
D --> E[High-strength Bolt Tightening]
E --> F[Purlin and Roof Panel Installation]
F --> G[Corrosion Coating Repair]
Processing: 1000 tons scale about 45 days (winter requires heated workshop)
Installation: 30m span standard unit, daily progress ≥ 300㎡
Cost Control Suggestions
Material Optimization
Main Material: Q355B steel pipe (wall thickness 4-8mm, reduces weight by 10-15% compared to Q235)
Joint: Bolt ball (saves 25% in labor costs compared to welded balls)
Project Unit Price Range Remarks
Framework Processing 750-1400 yuan/ton Includes bolt balls/welded balls
Installation Fee 200-450 yuan/ton Includes crane rental (winter +20%)
Galvanizing and Corrosion Protection 800-1200 yuan/ton Includes transportation to Jilin
Roof Panels 60-120 yuan/㎡ Suggest using YX51-380 type panels
Winter Construction Precautions
Welding rods need to be dried (350℃×1h), stored in insulated buckets on site
High-strength bolts are prohibited from being tightened below -10℃ (must be preheated to above 0℃)
Concrete Foundation
Add antifreeze (ensure foundation strength ≥ 70% of design value before installation)
Safety Measures
Anti-slip scaffolding (lay anti-slip mats)
Check hoisting steel wire ropes before starting work each day (risk of brittle fracture in low temperatures)
Project Testing and Acceptance Standards
Mandatory Inspection Items
Weld seam UT testing (sampling ratio ≥ 10%)
Bolt ball tensile test (3‰ sampling)
Deflection measurement (after loading ≤ span of 1/250)
Acceptance Specifications
"Quality Acceptance Standards for Steel Structure Engineering Construction" (GB50205-2020)
"Technical Regulations for Spatial Grid Structures" (JGJ7-2010)
