The terminal building of Beijing New Airport consists of a grid structure of nearly 52,000 tons?

It is reported that on the morning of June 30th, with the completion of the hoisting and splicing of the last steel grid structure, the steel structure of Beijing New Airport Terminal was successfully capped, and Beijing New Airport Terminal became the largest and most technically difficult single airport terminal in the world.

According to the report, eight giant C-shaped columns in the terminal building of the new airport are dotted around the core area. The largest C-shaped column is 28 meters high and weighs more than 500 tons, which is equivalent to the weight of 100 adult elephants. The distance between two C-shaped columns distributed in a right-angled straight line is 200 meters, which is enough to hold the whole water cube.

The steel grid structure of the terminal building includes two parts: the main terminal building and the finger gallery. It is composed of supporting system and steel roof structure, forming an irregular free-form surface space, with a total projected area of 310.3 million square meters, equivalent to 44 standard football fields, with a total weight of over 52,000 tons. Among them, the projected area of the roof steel structure of the main terminal building is 6.5438+0.8 million square meters, which is equivalent to 25 standard football fields; The total projected area of the finger gallery steel grid is about 6.5438+0.33 million square meters, and the maximum span is 465.438+0.6 meters.

The person in charge of the construction said that the combined weight of the new terminal building reached 52,000 tons, which is the heaviest steel roof in the single airport terminal building so far.
