Shanghai World Expo Textile Construction

Reflect the new features of Architecture

Many of the audience who visited World Expo were with the desire to see the world without going abroad.

As a matter of fact, they first came into contact with the unique buildings in the Expo Park, which represented the face of a country and a city.

Many countries have introduced the most advanced building materials and technologies in the stadiums and gymnasiums of the current World Expo. The industrial textiles used in the construction of World Expo stadiums have added a lot of color.

Tang Shifang focused on the advanced design of the German Pavilion and the Japanese pavilion and the industrial textiles for the venues.

He said that the main curtain wall of the German Pavilion is a special textile material, which is coated with a fluorescent agent to reflect the sunlight and reduce the energy consumption of the air conditioning in the exhibition hall.

The new textile material is light, breathable and recyclable, and can be made into handbags after the Expo.

In addition, this new material can play a role in beautifying the venue.

He went on to say that the building materials of the National Pavilion of Japan played a great role in the construction of its venues.

If its stadium's external walls use ETFE coated materials, the weight of the stadium will be greatly reduced, and a lot of steel will be saved.

The membrane material has two layers, the middle inflate, maintains 250 Pa air pressure.

Under this membrane, solar panels provide electricity for 50 52 Inch TV sets.

In particular, the design of the "circular breathing column" of the stadium is called the "breathing organism". On the one hand, it plays a supporting role in supporting steel and reduces the steel consumption by 40%. On the one hand, ventilation and ventilation, drainage of dirty air in the building, extraction of underground moist air, reduction of the temperature of the stadium, and refraction of sunlight at the same time can save electricity consumption.

It realizes the natural adjustment of light, water and wind.

The external light passes through the "circulation breathing column" to pmit natural light to the lower layer, enabling the interior space of the central part of the building to achieve natural daylighting. When it rains, the breathing column collects rainwater and sprinkles the collected rainwater to the roof, not only cleaning the roof, but also cooling the whole building.

The sprinkling water can also be recycled through this way; the chimney of the "circulation breathing column" can effectively form the updraft, and send the cooling air below into the building to reduce the temperature in the museum and reduce the air conditioning load.

Reporters in the German Pavilion personally feel its "harmonious city" architectural design style.

The German Pavilion is the largest in World Expo. It is designed and constructed by the German Munich Shek Kai Architectural Design Co., Ltd.

The architecture in the outer circle is like a three-dimensional sculpture that can enter and break the internal and external boundaries.

The total construction area is 6000 square meters and the exhibition area is 3600 square meters.

The building omental area is 12000 square meters, and it can accommodate 45000 visitors per day.

Although the manager of the German Department of the German Museum, the manager of the German Department of the press, did not disclose what textile materials were used in the building walls of the German Pavilion, but from her information to reporters, the silver fabric is a special kind of film, which can reduce ultraviolet radiation during the day, and can be used as a lighting carrier at night to provide facilities for lighting.

Moreover, this layer of pparent film can pform different scenes at different times and weather conditions.

The Japanese pavilion is like a "Purple cocoon". It is convenient for dismantling after the Expo. It does not use iron and steel as its foundation, but uses light building materials and recyclable materials.

Its facade architectural membrane material is called "the membrane that generates electricity and breathes".

The exterior walls of the stadium are all covered with different shapes of membrane materials and have the greatest degree of light pmittance. Inside the expanded pillow shaped membrane, internal power generation is accomplished through amorphous solar cells. The external structure not only saves energy, but also achieves the creation of energy, and the latest technologies such as circular breathing channels are used internally to maximize the use of natural resources such as light, water and air.

What should we learn?

During the interview, Tang Shifang also expressed his views on the latest technology and the use of new building materials in Expo Park.

He believes that China's architectural design and construction environment should be integrated with the world's advanced technology to enhance the integration technology capability.

For example, the passive building of Hamburg Museum, using hollow rock wool materials as heat insulation and airtight building materials, saves energy and reduces carbon emissions, which is worth learning in China.

The trend of textile development in many fields and across industries has become a trend.

The application of textiles in the field of construction in China has made great progress in recent years, such as fiber reinforcement of concrete and use of urban sunshade. However, compared with developed countries, it is far from popular.

At present, the developed countries in the world use advanced technology and new fiber materials in urban construction, sewage treatment, municipal engineering, etc., to achieve energy saving, emission reduction, zero carbon emissions and beautify the city.

Many new industrial textiles materials exhibited by the German Pavilion are a great feast for visitors.

Such as flax thermal insulation material,

By contrast, we also feel the gap between the application of advanced building materials in China and other countries.

Key technologies and materials such as the Beijing water cube and the Shanghai World Expo Axis are not yet fully available in China, and we still need imported products.

The Expo membrane structure is made up of membranes and cables. The membrane is a series of ETFE SF/1 products provided by Saint Gobain, USA, with a thickness of about 1 millimeters.

Because of the large volume of membrane between cables, it is difficult to use 300 ~400 C hot melt to splice.

The entire Expo Axis uses about 70000 square meters of membrane.

Xi Qunfeng, Minister of Engineering Department of Shanghai World Expo Coordination Bureau, told reporters.

At present, traditional textile industry is used in the process of industrial pformation.
