The rise of steel membrane structure coal shed

At present, the type of coal shed presents a diversified trend, in which the rise of steel membrane structure coal shed has aroused widespread concern in the industry, then, compared with the traditional coal shed, steel membrane structure coal shed in fact has what significant advantages? Next, we will discuss this in detail.

The advantages and disadvantages of construction

Traditional coal shed in the construction process, there is a high level of aerial work, large workload, insecurity and other issues.

In contrast, the steel membrane structure coal shed shows obvious advantages in the construction process. Its aerial operation level is secondary, and the workload is relatively low. Under the same area, the amount of aerial work and lifting work of steel membrane structure coal shed are greatly reduced, thus improving the safety and efficiency of construction.

The advantages and disadvantages of material fire resistance

Although the single-layer colour steel tile used in traditional coal shed is non-combustible material, its fire resistance limit is limited, generally 0.5 hours to 2 hours. The colour steel tile conducts heat quickly and easily ignites other combustible materials. Although the Code of Practice for Fire Protection in Building Design requires that the fire resistance limit of the roof be at least 1 hour and that fireproof coatings be applied, the effect of fireproof coatings is not satisfactory in the environment of the coal storage yard. Coal storage yards are often sprinkled with water to remove dust, and the air humidity is high, resulting in easy peeling of fireproof coatings; at the same time, the uneven surface of fireproof coatings is easy to adsorb coal dust, which is more likely to catch fire than coal in case of fire. In addition, the slag dripping from the melted colour steel tiles is also prone to ignite other combustible materials, and the escape routes may be blocked as a result.

In contrast, the membrane structure material used in the steel membrane structure coal shed has good fire resistance. Its fire resistance grade is B1 (B1 (refractory) grade is asphyxiated away from fire, i.e. automatically extinguished after leaving the fire source, or extinguished within 10 seconds), even if a fire occurs, the membrane material will not continue to burn and expand the fire after leaving the fire source. The holes formed after melting of the membrane can discharge smoke and gas, providing favourable conditions for escape. In addition, the steel structure part of the steel membrane structure coal shed can also adopt fire protection measures to improve the overall fire resistance.

Advantages and disadvantages of wind load and snow load resistance

When facing extreme weather conditions such as strong winds and heavy snow, traditional coal sheds may experience problems such as structural instability, tile shedding, and water and ice accumulation. Materials such as single-layer colour steel tiles have limited ability to withstand wind and snow loads, which may lead to damage or even collapse of the coal shed. In addition, the maintenance cost of traditional coal sheds is also relatively high, requiring regular inspections and repairs to cope with the erosion of various natural factors.

In contrast, steel membrane structure coal sheds have significant advantages in resisting wind loads and snow loads. The combination of its unique membrane structure design and high-strength steel structure enables the coal shed to maintain stable structural performance under extreme weather conditions. The membrane material has good elasticity and self-recovery ability, which can effectively resist the attack of wind and snow. In addition, the steel membrane structure coal shed also has excellent waterproof, corrosion resistance, aging resistance and other properties, which can greatly reduce the maintenance cost and extend the service life.

Therefore, steel membrane structure coal shed shows obvious advantages in construction, material fire resistance, resistance to wind load and snow load. With the continuous progress of science and technology and the increasing environmental protection requirements, steel membrane structure coal shed will become the mainstream trend of coal shed construction in the future. Of course, the steel membrane structure coal shed also needs to be improved and optimised in practice to meet the changing market demand and environmental requirements.
