Leaning against the mountains and the sea, national craftsman quality

Qingdao World Expo City is located in the coastal core area of the central vitality area on the west coast of Qingdao. It is built on the hillside and close to the sea. It is invested by the world's top 500 China Railway Group with an investment of 50 billion and designed by China Architecture Design and Research Institute. It covers an area of more than 3,000 acres. A high-quality complex low-carbon, blue ecological expo city integrating exhibition, conference, hotel, real estate, commerce, culture, tourism, leisure and other functions.

Structural art

In order to present the lightest structural form, a new type of pre-stressed cable arch is used in the design, with a section height of 500 mm and a span of up to 48 meters.

From the observation platform to the princes

The project was designed by the China Architecture Design and Research Institute, using the local historical relic "Langyatai" as its modeling intention, and introducing soft marine cultural elements, reflecting the organic unity of Chinese traditional culture and marine culture, and rich in aesthetic rhythm and visual impact. The pursuit of zero energy consumption reflects a full sense of science and technology everywhere.

From project planning and construction to internal function design, high technology is embodied in every link and every detail.

Among them, the roof of the pavilion adopts vertical seam aluminum-magnesium-manganese alloy material technology. While ensuring the beauty, good waterproof performance and durable use performance make it one of the highlights of the entire project.

The roof truss of each exhibition hall weighs 1,035 tons and is fixed by mechanical occlusion; the top of the exhibition gallery uses international advanced cable arch technology, which is stable and beautiful.

The entire facade of the Qingdao World Expo City project adopts a mixed tower technique, which is a mixture of shutters and metal curtain walls. This processing technique makes the entire facade of the curtain wall distinct, vivid and full of vitality.

The exterior wall of the pavilion adopts the metal wall system of Wiskind color diamonds. The standardized unit slats of more than 30,000 square meters are processed in the factory and quickly installed on site to realize the efficiency and accuracy of assembly installation.

Not only is it built quickly, but it also responds to the country's "green, energy-saving, and efficient" building requirements, and basically no other construction waste is produced.

In addition, the metal insulation sandwich panel material used in this project is 9 meters long and 1 meter wide. Not only the appearance is beautiful, but also the fire performance is excellent.

The core material is basalt wool with high water repellency and high bulk density (bulk density ≥120kg/m3), which makes the thermal insulation better. The fireproof cotton rotates at 90 degrees, so that the cotton fiber and the board surface become vertical, and the compressive and tensile strength is increased by more than 50%.

Both sides of the tongue and groove are filled with rigid polyurethane foam, which can effectively block heat conduction and rainwater leakage, and prevent the core material from reducing its strength and heat preservation performance due to moisture absorption.

Conclusion

From the Louvre and Notre Dame Cathedral in Paris, France, to the Milan Cathedral and La Scala in Milan, Italy, the Peace Hotel and Jin Mao Tower in Shanghai, China...there are many fashion capitals at home and abroad, and the urban architecture is unique.

In Qingdao, when the new landmark of the modern city meets the romantic sea, in the collision of elements, the curtain of art architecture is slowly opening, the vitality and creativity of the island city continue to burst, thus creating Qingdao World Expo City. A stylish art building standing on the shore of the Yellow Sea.
