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...

Construction Steps for Steel Structure Engineering

space frame engineering

Step 1: Site Preparation

Before commencing any construction activities, the site must be prepared. This involves clearing the area, ensuring proper drainage, and establishing temporary access roads if needed. Additionally, the site should be properly leveled and compacted to provide a stable foundation for the steel structure.


Step 2: Foundation Construction

The foundation is a critical component of any steel structure. Depending on the project requirements and soil conditions, different types of foundations such as pad footings, pile foundations, or raft foundations may be constructed. These foundations provide the necessary support and stability for the steel structure.


Step 3: Erection of Columns and Beams

Once the foundation is in place, the steel columns and beams are erected. This process involves lifting and placing the structural members into their designated positions. Cranes or other lifting equipment are commonly used for this purpose. Precise alignment and leveling are crucial to ensure the integrity and safety of the structure.


Step 4: Installation of Bracing and Purlins

Bracing elements are installed to provide lateral stability to the steel structure. These may include diagonal braces, shear walls, or cross-bracing systems. Additionally, purlins (horizontal members) are installed to support the roof covering and transfer loads to the main structural frame.



Step 5: Roof and Wall Cladding

Roof and wall cladding systems are installed to enclose the structure and provide weather protection. This may involve the installation of metal sheets, insulation, and vapor barriers. Proper sealing and flashing details are crucial to prevent water infiltration.


Step 6: Installation of Secondary Members

Secondary members, such as girts and eave struts, are installed to support the cladding and provide additional structural stability. These members are connected to the primary frame and contribute to the overall rigidity of the structure.


Step 7: Electrical and Mechanical Installations

Electrical and mechanical systems, including lighting, HVAC (Heating, Ventilation, and Air Conditioning), and any other necessary utilities, are installed. Proper coordination with the structural elements is essential to ensure that these systems integrate seamlessly with the steel structure.


Step 8: Fireproofing and Insulation

If required by local building codes or project specifications, fireproofing materials are applied to protect the steel members from high temperatures in case of a fire. Additionally, insulation materials may be installed to enhance energy efficiency and provide thermal comfort.


Step 9: Quality Control and Testing

Throughout the construction process, quality control measures are implemented to ensure that all work meets the specified standards and codes. This may involve inspections, material testing, and documentation of construction activities.


Step 10: Final Touches and Site Cleanup

In this phase, any remaining finishing touches are applied, such as painting, surface treatments, and the installation of safety features. The site is thoroughly cleaned and prepared for final inspection and handover.

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?

图片
  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...

Dreaming of vast, uninterrupted interior spaces for your next project? Steel space frame roofing offers a powerful and efficient solution for achieving impressive clear spans. Their unique three-dimensional truss system distributes loads effectively, allowing for lightweight yet incredibly strong structures ideal for arenas, warehouses, and commercial centers. At SAFS Steel Structure, we specialize in designing and delivering these innovative roofing systems. One key advantage of steel space frames is their efficient use of materials. The triangulated design maximizes strength while minimizing steel tonnage, leading to potential cost savings. Furthermore, the modular nature of space frames facilitates efficient prefabrication and streamlined on-site assembly. This faster construction timeline can significantly reduce overall project costs and accelerate occupancy. Beyond structural efficiency, space frames offer significant design flexibility. Architects can create ...
