Membrane structure architecture is the most representative brand-new architectural form in 2 1 century, and has become one of the main forms of long-span space architecture so far. It combines architecture, structural mechanics, fine chemical industry, material science and computer technology, and constructs a symbolic spatial structure. It not only embodies the beauty of the structure, but also fully shows the architect's vision and enjoys the romantic space of nature. In the architectural design of the 2008 Olympic Games, the application of membrane structure has been perfectly reflected.
"Water Cube" is the largest membrane structure project in the world, and the most advanced environmental protection and energy-saving ETFE (tetrafluoroethylene) membrane material is used outside the building. Tan, general manager of the National Gymnasium Project, revealed that the life of this material is more than 20 years, but it will actually be longer than this, and people can walk on it, which feels particularly good. At present, only three companies in the world can complete this membrane structure.
The whole building of "Water Cube" consists of more than 3,000 air pillows of different sizes and shapes, covering an area of 654.38+10,000 square meters, ranking first in the world. In addition to the ground, the exterior adopts membrane structure. The successfully installed air cushion will be inflated into "bubbles" through the inflation pipe installed on the steel frame in advance, and the whole inflation process will be intelligently monitored by the computer, and the "bubbles" will be kept in the best state according to the air pressure, lighting and other conditions at that time.
This kind of film material similar to "bubble bag" has self-cleaning function, which makes the film surface basically dust-free. Even if there is dust, natural precipitation is enough to make it clean as new. In addition, the membrane material has good compression resistance, so that people can "play trampoline" on it, and "it will not be crushed if a car is put on it normally". Once the adventitia breaks, according to the emergency plan, the damaged adventitia can be repaired or replaced within 8 hours. The glittering and translucent coat of "Water Cube" is also dotted with numerous white bright spots, called plating spots, which can change the direction of light and have the effect of heat insulation and astigmatism.
In addition, the "Water Cube" covers an area of 7.8 hectares without using a steel bar or a piece of concrete. Its wall and ceiling are connected by thin steel pipes, with1.2000 nodes. Only 2.4 mm thick membrane structure air pillow covers the whole building like skin. The largest air cushion is about 9 square meters, and the smallest is less than 1 square meter. Compared with glass, it can penetrate more sunlight and air, thus keeping the swimming pool at a constant temperature and saving electricity by 30%.
What is the water cube?
Perfect Embodiment of Membrane Structure —— Water Cube
Membrane structure architecture is the most representative brand-new architectural form in 2 1 century, and has become one of the main forms of long-span space architecture so far. It combines architecture, structural mechanics, fine chemical industry, material science and computer technology, and constructs a symbolic spatial structure. It not only embodies the beauty of the structure, but also fully shows the architect's vision and enjoys the romantic space of nature. In the architectural design of the 2008 Olympic Games, the application of membrane structure has been perfectly reflected.
"Water Cube" is the largest membrane structure project in the world. In addition to the ground, it is made of membrane structure -ETFE material. The blue surface is unexpectedly soft but full. Tan, general manager of the National Gymnasium Project, revealed that the life of this material is more than 20 years, but it will actually be longer than this, and people can walk on it, which feels particularly good. At present, only three companies in the world can complete this membrane structure.
"Considering the energy-saving standards of the venue, the membrane structure has strong heat insulation function; In addition, the maintenance of this structure is also very convenient. For example, after a gun or a sharp object is poked in, the monitoring computer will automatically appear. If a hole is broken, stick it with adhesive. The membrane structure is also very light, with good self-cleaning, dust is not easy to stick to it, and dust can also be discharged with rainwater. " Tan said that the membrane structure itself has the functions of drainage and sewage discharge, dehumidification and fog prevention, especially the function of dew prevention, which is particularly important for swimming.
As a building depicting water, the complex and free structure of the water cube stems from the ingenious and simple changes in the planning system. Simple and pure figures talk modestly with parents, and the contrast of different temperament makes their spirituality interesting. Coconut trees, beaches and artificial waves … sublimate the Olympic Arena into an eternal water park in the eyes of the world.
Wandering Life of Water Cube Designers
My name is John Pauline, and I come from Australia. If the "Water Cube" is mentioned, don't say that I designed it alone. We are a team. Three designers from China Architecture International Design Corporation came to Australia and cooperated with five members of our PTW architectural design team to design the "Water Cube". You know, sometimes, if the individuals in the team go their own way, the things they design will be very bad, but the "Water Cube" is a successful example. Although the background and culture are different, we have well integrated the design concept. Close your eyes and think about the future water cube. Bright sunlight shines through those blue bubbles during the day. You are lying on the artificial beach, with the sound of waves and the excited screams of surfers in your ears. When the lights are on at night, it is like a blue crystal palace. ...
You ask me what I like? I'm a little embarrassed to say it. I like all kinds of Olympic mascots. Those furry things are not all for girls. I have been keen on collecting mascots since I worked for the Sydney Olympic Games. Athena, Fevos, Sid, Millie and Ollie, Fuwa's Welcome to Beijing, and Ollie, the antelope of the Doha Asian Games, I already have many at home. They are all in the cupboard, but my wife stuffed them under the bed. She said that I was 38 years old and should not be so naive. In fact, she doesn't know that every mascot represents the place where I live and work. When I see them, I can remember the familiar past.
