Steel Space Frame Installation

Large Coal Storage Shed Space Frame

In terms of structural characteristics, the frame has three major advantages: first, high material utilization rate, the load is transferred to the surrounding supports through the spatial grid, and the steel consumption is reduced by 15%-20% compared with the portal frame; second, strong adaptability, the plane size can be flexibly adjusted according to the coal storage capacity, and a modular design with a span of 50-120 meters and a length of 100-300 meters has been achieved; third, convenient maintenance, the connection between the rod and the bolt ball is convenient for the replacement of a single component, greatly reducing the cost of later maintenance.

Overview of Space Frame Engineering of Large

Coal Storage Shed

  • Project Introduction
  • Core load design
  • Industry Value Summary

  • Project name: Shuozhou open-pit mine closed coal shed of China Energy Group

    Structural form: main frame space frame grid + (span 132m × length 398m)
    Technical innovation:
    The first wind-resistant cable net + damper integrated wind-resistant system in China (verified by 45m/s wind speed)
    Integrated unmanned bucket wheel machine automatic operation system (stack and reclaim accuracy ±0.3m)
    Economic benefits:
    Reduced coal loss by 120,000 tons per year (valued at 60 million yuan)
    Photovoltaic power generation 4.8GWh/year, covering 30% of operating energy consumption

  • Dead load: structure deadweight + roof system (≥0.5kN/m²)

    Live load: coal pile side pressure (equivalent uniform distribution 15-30kN/m²)

    Wind/snow: basic wind pressure 0.75kN/m² (value taken from Shanxi), snow pressure 0.4kN/m²

    Special load: bucket wheel excavator impact force (500kN point load)

  • The spatial framework of large coal storage sheds reconstructs coal logistics infrastructure with "large span, zero emission, strong intelligence, and fast recovery".
    Environmental protection hard constraints: completely solve the dust pollution of open-air coal storage and meet the new regulations of the "Air Pollution Prevention and Control Law".
    High operational efficiency: the coal loss rate is reduced to below 0.2%, and the railway loading efficiency exceeds 6,000 tons/hour.

Advantages and Features

Large column-free working space

The span is 100-150 meters without columns, the net height is ≥28 meters, and the bucket wheel stacker and reclaimer operation is fully covered. The coal storage density is increased by 40%, and the single shed capacity exceeds 300,000 tons, realizing efficient three-dimensional storage of coal piles.

Technical anchor point: pipe truss/grid system → release 100% of the working surface.

Extreme environmental protection dust suppression

Fully enclosed structure + intelligent spray system, PM10 concentration ≤1mg/m³ (national standard 5mg/m³), coal dust loss rate is reduced to below 0.2%, and the annual loss reduction benefit exceeds 2 million yuan/10,000 tons of reserves.

Technical anchor point: microporous spray coverage rate 98% → dust suppression rate＞95%.

Heavy-load safety redundant design

Cast-welded hybrid nodes + wind-resistant cable nets, bearing the lateral pressure of coal piles (30kN/m²) and the impact of bucket wheel excavators (500kN point load), passed the 32m/s wind tunnel verification, 8-degree seismic fortification, and 60 years of service life without major repairs.

Technical anchor point: Q390C high-strength steel → steel consumption 75kg/㎡.

Intelligent construction and low-carbon integration

Ground assembly + hydraulic synchronous lifting (error ≤3mm), shortening the construction period by 40%; pre-buried optical fiber sensors and photovoltaic brackets (installed capacity ≥2MW), reducing operation and maintenance costs by 60%, and reducing annual carbon emissions by 4,200 tons.

Technical anchor point: BIM-guided installation → accuracy ±2mm.
