Prefab steel structure hangar

Prefab steel structure hangar is referred to as the hangar. It is a large-span single-storey building during aircraft maintenance and the main building of the aircraft maintenance area. The plane layout, building height and structural form of the hangar also vary according to the amount of aircraft maintenance and the requirements of the maintenance items. 

1.Prefab steel structure hangar factors:

① The type and quantity of the aircraft to be repaired At the same time, the maintenance items and the need for maintenance

② The requirements and restrictions on the height and layout of the hangar structure;

③ The setting requirements for hangar doors, cranes and working platforms;

④ The configuration requirements for firefighting facilities inside and outside the hangar:

⑤ Site conditions and development trends.

2.Advantages of prefab steel structure hangar

Structural form The plane layout and height requirements of the hangar are quite special. Directly affects the structural form of the hangar. Due to the large span of the hangar. The proportion of the self-weight of the roof system structure in the total load is also relatively large. If the self-weight of the structure can be reduced. obvious economic effects can be obtained. The steel structure has the advantages of high strength. Light weight, small cross-section of components, weldability, and relatively simple manufacturing process. Therefore, it is more common to use steel structure as the roof bearing system in large-span structures.

3.Steel structure engineering case

The space structure system has good force and light weight. And can solve some problems that cannot be solved by the plane structure system. Shell structure, grid structure, suspension structure and other space structures have been widely used as roof systems for large-span buildings. The frame structure has a plane size of 80X 48 meters and is composed of prefabricated tubular trusses. The material is high-strength steel with a yield strength of 355 MPa. The entire roof is supported on 8 columns. In addition to the general load, the roof also bears the weight of 700 tons of equipment.

In addition, the hangar roof of Frankfurt Airport in Germany adopts a suspended plate belt structure, with a plane size of 270X 100 meters and two spans. Each span consists of 10 strips with a length of 135 meters and a width of 7 meters.The prefab steel structure hangar door has a special structure due to its large size. Heavy weight, and easy opening. In order to facilitate the towing aircraft into and out of the hangar.

4.Details of prefab hangars

Prefab hangar door is usually designed according to the full height of the hangar. And the whole length is divided into several leaves, each about 10~20 meters wide, with a special guide structure on the top of each door leaf, and the bottom of the door leaf is supported on the track. On the wheel; the door leaf can be made of a steel frame covered with thin steel plates. with a thickness of about 500~700 mm. For some hangar doors, according to the shape of the aircraft. The center is high and the two sides are low, the door is designed in the shape of a “pin”. High control.

The prefab steel structure hangar has a large space. And many aircraft are often maintained in the hangar. All kinds of maintenance equipment and working platforms are accompanied by oil, gas, electricity and other flammable and explosive sources. There should be strict requirements and perfect facilities for fire prevention and explosion protection. At present, high-expansion foam fire extinguishing systems are mostly used.
