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

图片
 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...

What are the advantages of membrane structure?

  What are the advantages of membrane structure? Membrane structure 1. Artistic: novel and beautiful, reflecting the beauty of the structure, and rich in color. 2. Economy: because the membrane has a certain light transmission rate, the lighting intensity and time can be reduced during the day, which can save energy very well. 2. Economy: Since the membrane has a certain light transmission rate, it can reduce the intensity and time of lighting during the day, which can save energy well. 3. Large span: membrane structure can fundamentally overcome the difficulties encountered in the realization of traditional structures on large span (unsupported) buildings. 4. Self-cleaning: the use of membrane materials with protective coating in membrane buildings can give the building a good white clean effect while ensuring the service life of the building. 5. Short construction period: all processing and production in membrane building projects are done in the factory, which can reduce the co...

  What is the difference between Glass floss and rock wool? Glass floss Rock wool 1. The difference in production materials Glass floss  is made of glass as the main raw material Rock wool is made of exquisite basalt as the main material 2. the difference in product use Glass floss  is generally used for insulation parts below 200 degrees Celsius, mostly for general building or low temperature pipeline insulation. Rock wool is generally used for insulation parts with a temperature of 500 degrees Celsius, mostly used for insulation of high-temperature heat pipes or electric power equipment.

  The chessboard -shaped quadrilateral mesh grid has good overall and stability, flexible plane layout, the upper string rod of the structure is short and the lower chord is long. The rods of the exchange are relatively small, the roof structure is simple, and the construction is convenient. The emergence of a large number of new materials, new processes, and new technologies in modern times fully reflects the advancedness, economy and rationality of the grid structure. In the future, the chessboard -shaped quadrilateral cone network shelf will be used more and more many.
