Zhengzhou International Convention and Exhibition Center, jointly designed by Chinese and Japanese architects and engineers, is a highly integrated design of architectural art and technology. This paper analyzes the design concept of Zhengzhou International Convention and Exhibition Center in detail from the aspects of design background, spatial form, functional composition and technical application, trying to express the image of Zhengzhou's rapidly developing economy through this building.
Zhengzhou has a long history and splendid culture. Zhengzhou National Sugar, Tobacco and Alcohol Fair and Zhengzhou National Commodities Fair held here made Zhengzhou famous. However, in the past 10 years, due to the backwardness of venue facilities, Zhengzhou seems to be drifting away from the sight of convention and exhibition industry. Zhengzhou International Convention and Exhibition Center, which will be put into use soon, will make Zhengzhou's exhibition hall conditions re-enter the ranks of advanced cities in China and bring new opportunities for the development of Zhengzhou's convention and exhibition industry.
Design background
In order to promote urban development and build a regional central city, Zhengzhou Municipal Party Committee and Municipal Government decided to build Zhengdong New District in the east of Zhengzhou. In the international competition, Japan Kurokawa Zhangji Architecture? Therefore, the concepts of "metabolism" and "city of birth" stand out in urban design affairs. CBD Central Business District, as the starting area, is an annular city formed by high-rise buildings around Central Park and along the ring road, and the center of Central Park is the central pool. The buildings are arranged around the central pool, forming a road far away from the waterfront, putting the buildings in the water in an elegant pattern, and forming a landscape in which the buildings in urban blocks are reflected in the water. Zhengzhou International Convention and Exhibition Center, Henan Art Center and Zhengzhou Convention and Exhibition Hotel have become the landmark buildings of CBD. Zhengzhou International Convention and Exhibition Center is the largest single building and the largest shared area among the three landmark buildings, and it is also the largest public building with single investment in Zhengzhou history, which was built by Kurokawa Zhangji. The urban design firm and the Sixth Design and Research Institute of the Ministry of Machinery jointly designed the project, and the engineering design won the "Annual Meeting of World Architects" and the first "Outstanding Award of Urban Planning and Design", which is the core project and engine project of Zhengdong New District and has important strategic significance.
Image spirit
Zhengzhou International Convention and Exhibition Center is located in the CBD center of Zhengdong New District, adjacent to 107 National Highway and Beijing-Zhuhai Expressway. It is 26 kilometers away from Zhengzhou Xinzheng International Airport with convenient transportation. It is a large-scale comprehensive modern conference and exhibition facility integrating exhibition, conference, business, catering, leisure and sightseeing, with complete functions, advanced facilities and perfect services.
Exhibition economy has a great pulling effect on a city's economy, and high-quality exhibition venues are the material basis and guarantee for the development of exhibition economy. A high-level international convention and exhibition center, because of its advanced technology, often becomes a symbol of modernization and internationalization of a city.
Due to the geographical location of Zhengzhou International Convention and Exhibition Center and its irreplaceable important role in the group building in Zhengdong New District, architect Zhang Ji Kurokawa adopted a romantic design method, winding the building along the pool and setting a viewing corridor around the water surface to reflect the water surface. The roof adopts long-span all-steel structure. 1 1 group space cable-stayed system goes straight into the sky, constructing a romantic and light form. The facade facing the swimming pool adopts light-colored glass curtain wall. The perfect combination of steel roof, fair-faced concrete wall and glass curtain wall makes the architectural style and modeling have oriental charm and become the symbol of this beautiful city in Zhengdong New District.
functional composition
Zhengzhou International Convention and Exhibition Center covers a total area of 685,700 square meters with a building area of 265,438+440,000 square meters. Mainly used for conferences and exhibitions, it is divided into two parts: conference center and exhibition center. The plane of the exhibition part is fan-shaped and belt-shaped, with a construction area of153,600 square meters. There can be 3560 international standard booths. There are two floors in the exhibition hall, and the second floor has no columns, which is a large exhibition hall of 72,000 m2. The conference part has a circular layout with a building area of 60,800 square meters. It consists of a multi-function hall with a capacity of 5,000 people, an international lecture hall with a capacity of 1.200 people, two conference halls with a capacity of 400 people and more than a dozen small and medium-sized conference rooms. The whole exhibition center is divided into two phases. The first phase includes the bus terminal, the second bus station, the conference center (including the guidance hall), the exhibition center (about 6.5438+0.3 million ㎡) and about 2,200 outdoor parking lots. The second phase of construction includes the expansion of the convention and exhibition center, * * * 65,438+500,000 square meters, and about 2,200 sets of underground parking lots.
Facade texture
The overall design concept of Zhengzhou International Convention and Exhibition Center is to create a 2 1 century international-level large-scale exhibition building image in the CBD area of Zhengdong New District. The convention and exhibition center is located in the central park of the new city center with beautiful scenery, covering an area of about 83 hectares. The exhibition part of the convention and exhibition center is arranged in an arc shape, enclosing the central pool, forming a harmonious situation of water areas, parks and buildings, and pursuing the harmony between architecture and urban space.
The exhibition center and conference center of the convention and exhibition center are relatively independent, but they maintain the overall form of harmony and have delicate facade texture.
The exhibition center consists of a suspended roof, a precast concrete exhibition space and two reinforced concrete annex buildings. The roof adopts a suspended roof structure composed of beam string and steel cable, and the carefully arranged suspenders produce a strong visual feeling and establish a romantic symbolic image. The whole roof structure is novel and unique, which dispels the huge sense of mass of the whole building and makes the building more harmonious with the whole environment. Because the length of the first phase of the whole convention and exhibition center reached 390m, after the completion of the second phase, it reached an amazing 840m, forming a large-scale continuous wall. In order to eliminate the oppressive feeling of the huge wall, the height of the building is reduced in the design, and the external wall design focuses on the transverse joints, which is close to the scale based on the human body. The large-scale suspended roof does not directly collide with the concrete annex buildings on both sides, but uses glass as the transition, which weakens the overall volume and highlights the lightweight effect of the roof. Facing the central waters of the Central Park, the facade of the exhibition building is composed of glass and metal sun visor, which forms an expression full of the flavor of the times. Passing through the viewing corridor between the central pool and the exhibition hall, the landscape and light blend, permeate and flow here, leaving a deep impression on people's hearts.
The conference center is composed of a central mast, a folding grid roof and V-shaped tree supports on the periphery, showing a slim and light image as a whole. The suspension cable set on the central column further highlights the lightness of the conference center. A circular skylight is arranged in the center of the folded-plate lattice roof, so that the natural light diffuses in from the transparent body of the roof and gradually brightens along the truss structure, which has a centripetal feeling and soft and elegant light, and enhances the structural expression of the truss structure. The indoor roof has no suspended ceiling and the structure is exposed. Use the special shape and technical expression of the roof structure to show the harmonious overall effect in the change. The structural components are concise, clear in force transmission, light and transparent, which reduces the closed oppression and fully demonstrates the perfect combination of architectural art and technology. The facade is consistent with the concept of the exhibition center. The concrete outer wall is separated from the roof, with glass as the transition. According to the form of the roof, the glass part is triangular, and its window frames are radial, which makes the facade which is easy to produce monotonous appearance have a unique visual image.
Technical expression
The development of modern science and technology has a great influence on architectural modeling. The combination of technology and art has changed the concept of architectural creation, expanded the methods and expressive force of architectural design, broken the previous framework of pursuing modeling expression only from the aesthetic point of view, and created a "technical thinking" to capture the internal relationship between structure, structure, equipment technology and architectural modeling from the scientific and technological point of view, and sublimated technology into art, making it a means of expression full of the times.
Zhengzhou International Convention and Exhibition Center is a novel project with high technology content. Among them, the exhibition center consists of rectangular units and fan-shaped units, with a span of 102m and a width of 60m. The largest column network on the first floor is 30×30m, and there are no columns on the second floor, which is a large exhibition hall with a roof of 72,000m2 and 40.5m Some roof systems in the exhibition center use cables on the mast to connect the prestressed cable arches across the side and in the middle of the span in blocks, forming a spatial cable-stayed prestressed cable arch structure system. Among them, the mid-span of the roof system is divided into cable-arch members composed of cables and structural rigid arches, and 1 mast and six cables are combined to form 1 spatial cable-stayed system. This long-span spatial structure is a new hybrid form of cable-stayed structure system, and no completely similar engineering example has been found yet. The whole structural system is concise and clear, with strong technical aesthetic expression, and the form and function are perfectly unified.
The roof of the conference center is light and elegant, shaped like an open umbrella, and consists of a central mast and cables, an outer ring support system and a roof folding truss. The roof truss at the center of the circle is evenly distributed along the radial direction of the circular roof, forming a stable system with the inner and outer rings, and 12 groups of tree-shaped support columns and the outer ring truss form a rigid lateral force resisting frame.
Technology is a tool, an architect's language and a form of expression here. Architects express an aesthetic experience through technology, and technology and art really blend together.
The construction idea of Zhengdong New District is the Central Plains practice of Kurokawa's "metabolism" theory, and Zhengzhou International Convention and Exhibition Center is the crowning touch for Kurokawa to implement this idea. If the beautiful Zhengdong New District is compared to a bright eye, then Zhengzhou International Convention and Exhibition Center is the shining brilliance in this bright eye.
