The prefabricated metal structure hangar is referred to as the hangar, which is the main building of the aircraft maintenance area. According to the different requirements of aircraft maintenance quantity and maintenance items, the plane layout, building height and structural form of the hangar are also different. Mainly depends on the following factors:
The type and quantity of aircraft to be maintained at the same time, the maintenance items and the degree of maintenance required.
Requirements and restrictions on structural height and layout of metal hangars.
Design requirements for hangar doors, cranes and working platforms.
Configuration requirements for fire-fighting facilities inside and outside the prefabricated hangar.
Hangar building site conditions and development trends.
Structural form of prefabricated hangar
The layout and height requirements of the prefabricated metal hangar building are special, which directly affect the structure of the metal hangar. Due to the large span of the hangar, the proportion of the structure’s self-weight in the total load is also large. If the self-weight of the structure can be reduced, obvious economic benefits can be obtained. The metal structure of the prefabricated hangar has the advantages of high strength, light weight, small cross-section, good weldability, and simple manufacturing process.
With the continuous development of steel structures, steel structure hangars are also increasing. Steel structures have the advantages of being green, healthy, and environmentally friendly. They can also withstand strong winds and earthquakes, and can save a lot of materials, manpower, and costs during construction. There are many ways to improve the quality of prefabricated metal structure hangars, the common ones are:
1. When designing drawings, each step must be very obvious and clear.
2. Improve the quality of construction in details such as material suppliers, construction, protective measures, and transportation.
3. When selecting materials, it should be selected according to different steel profiles, construction environment and location and other conditions.
4. During the whole process of material production, processing and building construction, construction workers should communicate with technical personnel.
