What is the big earth model like Hangzhou Olympic Games?

Hangzhou's landmark "the sun and the moon shine together"

That ball is the Sun-Hangzhou International Conference Center.

Next to the semicircle is the moon-Hangzhou Grand Theatre.

Project name: Hangzhou International Conference Center

The project is located at the intersection of Jiefang East Road and Jiangjiang Road in Hangzhou, on the central axis of Qianjiang New City (New Town Blog, New Town News and New Town Talk).

The construction scale covers an area of 980 mu, with an investment of 2 billion yuan and a total construction area of 500,000 square meters.

Contractor: Zhejiang Great Wall Construction Group

The design unit is designed by Mr. Xia Bangji, a world-famous design master, and the GS company of the United States carries out the scheme design.

Project progress: On August 2, 20071day, the steel structure of the main building was capped; It is planned to be completed and put into use in the first half of 2009.

Expert Comments Hangzhou is famous for its beautiful natural scenery and rich cultural accumulation. At the same time, it is adjacent to Shanghai and has obvious geographical advantages. In recent years, the city has taken the international convention and exhibition city as its development goal. The construction of Hangzhou International Conference Center is expected to solve the "bottleneck" of the backward development of existing exhibition venues with small scale and low grade, and let Hangzhou take the lead in entering an international exhibition metropolis. Hangzhou International Conference Center is a landmark building integrating a large conference center and a super five-star hotel. The open underground space wave cultural city connects it with important buildings such as Hangzhou Citizen Center, Hangzhou Grand Theatre and city balcony, forming the central area with the most cultural taste and commercial value in Qianjiang New City.

Standing by the Qiantang River in Hangzhou, the Hangzhou International Conference Center with steel structure looks like the Bird's Nest, the main stadium of Beijing 2008 Olympic Games. Recently, the project of Hangzhou International Conference Center has gradually taken shape. It is reported that the Hangzhou International Conference Center is a steel structure with a height of 85 meters. The main body consists of an oval platform with a height of13m and a sphere with a diameter of 85m. It is planned to be completed and put into use in the first half of 2009. The completed Hangzhou International Conference Center and the half-moon silver-tone Hangzhou Grand Theatre are like a pair of sister buildings. One day in January, one gold and one silver set each other off in the blue waves of Qiantang River, forming a scene of "the sun and the moon shine together".

Engineering analysis

Building the largest international conference center in China.

In recent years, convention and exhibition economy has become a new bright spot of economic growth in various places. As a famous scenic tourist city, Hangzhou has a beautiful natural environment, rich cultural landscape, good public security and convenient traffic environment, which makes it have the foundation for developing exhibition economy. However, at present, the venues for holding large-scale international exhibitions in Hangzhou are very limited, with small exhibition area, incomplete facilities and insufficient affordability. The shortage of exhibition venues has become the bottleneck of the development of exhibition industry in Hangzhou.

According to the person in charge of Qianjiang New Town Construction Management Committee in Hangzhou, as a national tourist resort, Zhijiang Resort in Hangzhou will build a large-scale convention and exhibition center in the local area with its beautiful natural environment, superior geographical location, preferential land policy, perfect supporting facilities and confidence in the development of Hangzhou convention and exhibition industry, which can drive the development of the whole resort and promote the development of Hangzhou convention and exhibition industry.

The functional design of Hangzhou International Conference Center is based on holding large-scale international conferences and platinum five-star hotels, and it has many functions such as meeting, banquet, performance, accommodation, catering, entertainment and leisure. Its building is divided into three parts: basement, podium and spherical main body. There are two floors in the basement, of which the second floor is an underground parking garage, and the first floor is a hotel, conference equipment room and supporting auxiliary room. The podium is divided into two layers. The first floor consists of a 2000-square-meter grand ballroom and a kitchen for preparing meals, a 1000-seat grand conference hall, a medium-sized conference hall and a press conference hall, and the second floor is a small conference hall. The spherical main building is a platinum five-star hotel with more than 400 rooms, including catering and entertainment services. The third floor is the restaurant floor of the hotel. The hotel has a high spherical atrium space from the lobby floor of 18 meters to the top, and a fan-shaped open surface is opened in the direction of the Grand Theatre to introduce outdoor space into the room, forming a variety of light and shadow effects. 16th floor rooms are arranged around the spherical atrium, and the truss at the top of the atrium is exposed, and the sky is the same color, enjoying the beautiful scenery of nature. /kloc-above the 0/6th floor is the leisure and sports area of the hotel, such as indoor swimming pool, sauna area and fitness area. Underground is a 52,000 square meter parking garage.

Hangzhou International Conference Center covers an area of 980 mu, including international conference center, international exhibition center, large central plaza, hotels, conference clubs and resorts. Its conference and exhibition area will reach 260,000 square meters. Upon completion, the conference center will be one of the largest comprehensive service exhibition centers in the world and the largest international conference center planned and designed in China at present.

Build the largest steel spherical building in China.

Hangzhou International Conference Center was built by Zhejiang Great Wall Construction Group. According to the person in charge of the company, Hangzhou International Conference Center consists of a spherical main building on the ground 19 floor and a group room on two floors, in which the diameter of the sphere reaches 85 meters. This project is not only the landmark building of Qianjiang New Town, the first super five-star hotel in Hangzhou, but also the largest steel structure public building project in Zhejiang Province.

According to the construction party, the International Conference Center is mainly composed of 19-story frame main building, steel truss podium and two-story basement. The height of the whole building is 85 meters, the maximum diameter of the main structure (sphere) is 85 meters, and the total construction area is130,000 square meters. It is the largest spherical steel structure building in China at present, with thousands of steel members, large and small, with a total steel consumption of 60,000. Judging from the construction progress, from the ground operation to the closure of the dome, it takes only about half a year for the construction personnel to set up the whole "sphere", which is the advantage of the steel structure building. All components can be produced in the factory, without the trouble of pouring concrete, and the construction period is particularly short.

According to technicians, although the construction of the steel ball building is not a new technology now, it is not easy to make the whole ball look "round". The biggest difficulty is to ensure the radian. In order to ensure the architectural effect, the steel columns of the main building are vertical arc members, and the steel is also very good, just like the Bird's Nest, the main stadium of the Beijing Olympic Games. Because the radian of each floor is different, the height of each floor is slightly different, generally staying between 3.6 meters and 6 meters. The fifth floor is relatively high, about 6 meters high. Because this is the starting position of the spherical arc, the stress situation is also the most complicated and the construction is the most difficult. Cast steel members with good strength and toughness are adopted, and the heaviest one weighs 16 tons.
