Eight groups of C-shaped columns hold up the "phoenix wings" roof
Under the winter sun, the new airport terminal building in Beijing stands tall, like a phoenix spreading its wings. The new airport terminal in Beijing stands tall in the winter sunshine, like a phoenix spreading its wings, shining brightly.
"Realizing efficient transfer is the most central feature of the terminal. We have designed a double-in, double-out model to improve travel efficiency for passengers. The distance from the drop-off point to the end is more than 600 meters, and it takes up to eight minutes of walking to board a plane. In addition, there is a high-speed railway underground, which basically realizes zero-distance transfer." Li Jianhua, deputy general director of the new airport construction command department and manager of the general contracting department of the terminal building project of Beijing Urban Construction Group, said.
For the delivery of materials to repair two train tracks
Into the main terminal building of the new airport, Li Jianhua introduced the main terminal building not long ago completed the roof sealing, the entire construction process can be described as a "major new and high technology".
"The most construction workers 35,000 people," Li Jianhua introduced, including airport engineering, airline bases, fuel supply engineering, air traffic control, port facilities, rail and highway, construction units, construction companies hundreds.
The new airport terminal complex is currently the world's largest single terminal, with a total construction area of more than 1.42 million square meters, including the passenger terminal building (core area and five finger corridors), the integrated transportation center (parking building and comprehensive service building) engineering and underground track. Among them, Beijing Urban Construction is responsible for 600,000 square meters, which is the most core and complex part, with a single floor area that can put down a Bird's Nest, equivalent to 25 soccer fields.
The amount of concrete poured for the main terminal section reached 1.05 million cubic meters, which is equivalent to building 25 18-story high-rise buildings on average every month. At the peak of construction, there were 8,000 people working here at the same time," Li said. Normally, the materials used can't be transported here by hand or even by cranes. At that time, two train tracks were built here to transport materials here by train."
1,152 vibration isolation bearings to dissipate the vibration of the high-speed rail
The terminal building introduces the high-speed rail into the building, but also introduces a difficult problem, how to reduce the vibration? Li Jianhua introduced the high-speed rail layer of all the top columns, are retrofitted with rubber vibration isolation bearing, a *** with 1152, is the world's largest single building dosage, the largest vibration isolation bearing diameter of more than two meters, is also the world's largest. He said, vibration isolation bearing formed a seismic isolation layer, can be vibration are absorbed. Previously used in Kunming Airport, but the amount is not so large.
On June 30 last year, the entire steel structure net construction was completed, with a total weight of more than 42,000 tons, comparable to the weight of the Bird's Nest shell. The entire curved surface modeling, took less than 3 months to complete. This mesh surface, is a phoenix shape roof steel mesh frame. more than 60,000 steel frame, more than 12,000 connection ball, are welded up.
The phoenix-shaped roof steel mesh frame must be accurately positioned, the complexity of the assembly technology, the difficulty of installation is extremely high. Li Jianhua said that the terminal building roof's ability to resist wind uncovering has been improved to a great extent than previous buildings. Aluminum-zinc-plated steel plate used for the roof plate, previously used aluminum-manganese-magnesium plate, the new material is more rigid, less deformation. After many wind tunnel tests, the connection system has been researched to make the overall structure safer and more secure against typhoons of one in a hundred years.
Lee said the construction team went to work at 7 a.m. and left work after 10 p.m. for three consecutive months, and eventually completed the task two days ahead of schedule.
More than 8,000 pieces of roof glass are different
The roof of the new terminal covers an area of 180,000 square meters, also the largest in the world. The main natural lighting system at the top of the terminal consists of a central skylight, six strip skylights, eight bubble windows and a lighting strip running through the middle of the finger corridor.
It is reported that the entire terminal **** uses 12,800 pieces of glass, of which more than 8,000 pieces are used for the roof. Li Jianhua said that because the roof is constructed with streamlined curved surfaces, no two pieces of glass in the 8,000 pieces are the same. Each piece of glass *** has four layers, the upper and lower layers are glass layer, the middle of the hollow layer, filled with metal louvers, can block the midday light, but also to meet the natural lighting needs of the terminal building.
In order to reserve enough space for activities, the entire large roof of the terminal building is supported by eight groups of C-shaped columns. Li Jianhua told reporters at the scene, pointing to the columns, 2 groups in the south, 2 groups in the middle, 4 groups in the north, "the middle of the position, the span of 180 meters, can put down a water cube".
Li Jianhua introduced, this year, the terminal building construction work will be more heavy task, more arduous, "to achieve the effect of the car on the bridge, can enter the building". Among them, the terminal building facade to be all debut, to achieve the design effect. The effect of the interior large area of the finishing touches to come out.
