The total construction area of the wide-body passenger aircraft parts production steel structure warehouse is 528,383 square meters.
The main structure of the steel building warehouse is an assembled steel structure with a steel volume of 13,000 tons or more, the maximum span of the steel structure is 69 meters and the projected area of the space frame is over 100,000 square meters.
Mainly including No. A01 aircraft large composite component manufacturing plant (floor area 47,116 square meters);
No. A02 aircraft large composite component assembly plant (floor area 432,248 square meters);
No. B01 aviation science and technology research and development center (floor area 37,713 square meters),;
No. B02 dormitory building (floor area 11,146 square meters), No. A06 gatehouse ( building area of 30 square meters);
No. A07 gatehouse (building area of 30 square meters);
No. A08 metering room (building area of 10 square meters);
No. B03 gatehouse (building area of 60 square meters);
No. B04 refuse station (building area of 30 square meters) and basement.
The maximum span of the steel space frame in the hot press tank area is 63 meters, the total length is 124 meters, and the projected area is 14,000 square meters, which is about the size of 33 basketball courts; the lifting height is 15 meters, and the total lifting weight is 438 tons; the lifting plan adopts the construction technology of “in-situ assembling on the ground + synchronous lifting of the whole hydraulic system”, which is completed on the ground first. The steel space frame is assembled on the ground first, and then lifted in two stages, the first time by 1.5m height and then by crane, and the second time by lifting the whole structure to the design elevation.
