Selection and Application of Structural Steel Materials for Aircraft Maintenance Hangars​

-

 Aircraft maintenance hangars , as the core facilities for aircraft inspection and repair operations, must endure long-term exposure to large-span loads, extreme weather conditions, and complex operational environments. Consequently, stringent requirements are imposed on the strength, weather resistance, and stability of the structural steel materials employed. The judicious selection of suitable steel structural materials not only ensures the hangar's safe operation but also reduces construction and maintenance costs. Based on the functional requirements of different structural components within the hangar, commonly used steel structural materials can be categorised into three main types, each playing a critical role in hangar construction. I. Primary Load-Bearing Structure: The Core Material Supporting the Hangar's ‘Skeleton’ The primary load-bearing structure forms the hangar's ‘skeleton’, bearing the hangar's own weight, aircraft parking loads, and external forces s...

The economic benefits brought by steel structure

-

 "A new building system can open up the industry line between construction, metallurgy, machinery and equipment manufacturing, new building materials and disaster prevention and reduction industries, become a national strategic resource reserve, and integrate innovation into a strategic emerging industry." Steel structure houses are conducive to economic transformation and upgrading and sustainable development, and need to accelerate cultivation and development." This is a few years ago, the industry is generally optimistic about the steel structure building system.

Steel structure residential general system for residential use, with unique advantages, including: first, light weight. Steel structure housing can reduce the building weight of about 30%-25%, which is conducive to the construction of high-rise buildings, especially in places with low geological carrying capacity and high seismic intensity, and its comprehensive economic benefits are better than ordinary residential building systems. Secondly, the layout is flexible, the room is large, and the room type is rich, which can increase the construction area by 3%-25% to 5%-25%. Due to its full flexibility, modifiability and safety, it is conducive to meeting the needs of modern life. Third, it is easier to achieve industrialization, standardization, mass production, and improve the structure of the labor week.



Steel structure steel is facing the new challenges of the rapid development of China's steel structure industry, and the increasing amount of steel used in steel structure has also accelerated the production and research and development of steel used in steel structure. However, compared with developed countries, there are still many gaps:

The proportion of high-performance steel used in steel structures needs to be improved. In addition to the advantages of light weight, high strength, excellent material properties, high industrialization of production and installation, suitable disassembly, and good durability, building steel structure also has the characteristics of saving resources, reducing carbon emissions, recycling and so on. Therefore, the steel used in the steel structure also needs to be light in weight, high in strength and corrosion resistance. However, at present, some steel structure projects still have the defects of "stupid, heavy and large", and high-grade structural steel is needed to change the status quo. For example, carbon structural steel (Q235) can be replaced by low-alloy high-strength structural steel.

What is a coal bunker?

Coal bunker , is a structure used for storing coal. Coal bunkers play an important role in thermal power plants, coal mines and coal marshalling stations. Depending on the specific application scenario and design, there are various types of coal bunkers, such as circular coal bunkers, square coal bunkers and open coal yards. Safety Management of coal bunkers Preventing spontaneous combustion of coal: Since coal itself contains certain moisture and volatile substances, long-term exposure to the air may lead to spontaneous combustion, so the safe management of coal bunkers is of great significance in preventing spontaneous combustion of coal. Ensure the quality of coal: coal in the coal bunker usually needs to be stored for a long time, if not managed properly, it may lead to the decline in the quality of coal, such as sulphurisation, weathering and other phenomena, so it is necessary to ensure the quality of coal by strengthening the safety management of the coal bunker. Improve the eco...

What is the difference between a single-layer reticulated shell and a double-layerreticulated shell?

  The differences between single-layer reticulated shells and double-layer reticulated shells are as follows: Structural Configuration   Single-layer reticulated shell: Composed of a single layer of members, with the members directly connected to form a grid structure . The node configuration is relatively simple, typically employing rigid connections that allow the members to bear not only axial forces but also bending moments and shear forces.   Double-layer reticulated shell: Consists of upper and lower parallel layers of members connected by web members, forming a truss-like structural system. The nodes are generally hinged, and the members primarily bear axial forces. Its configuration is relatively complex, requiring more members and nodes to ensure structural stability and load-bearing capacity. Structure Single-layer mesh shell: composed of one layer of rods, the rods are directly connected to form a mesh structure, the node structure is relatively simple, usually...

What are the differences between bolted ball grids and welded ball grids?

-
图片
 There are a number of differences between bolted ball grids and welded ball grids in terms of fabrication, construction and design. The following are specific comparisons: 1. Manufacturing process: The manufacturing of bolted ball net frame is mainly carried out in the factory, using mechanical shot blasting to remove rust, and then spraying paint, plastic spraying or zinc spraying treatment to enhance corrosion resistance.  The steel pipe and welded seam of welded ball mesh frame can only be descaled manually on site, and then paint or fireproof coating is brushed. For the welded part, it needs to be descaled and brushed at a stage to maintain, which increases the cost of later use and affects the safety of the structure. 2. Construction process: 70% of the workload of bolted ball grid frame is prefabricated in the factory, 30% of the workload is installed at the site, only a wrench is needed to tighten the bolts at the site, which is easy and fast, and can be constructed ...
