The 'bird's nest' has caused a stir in the industry, and the crux of the matter is whether the roof of the stadium should be opened. Considering the comprehensive reason of the diameter of 'bird's nest', the original design can be cancelled by the builder. For a moment, the open roof became a picture of the "moon cake" being put into the cold palace.
In fact, it is increasingly necessary and fashionable to build large sports buildings with open and closed roofs. Because can open and close, roof of sports building of the largest function shows the maximum blend of nature and human being, and is not affected by natural reason to sports activities, avoid closed-end structure to high energy consumption during certain seasons to maintain physical activity of a new kind of architectural style. As early as 1961, the United States built the Pittsburgh civic stadium with a modern traction drive, with a span of 127 meters. The famous architectural design master of our country, ma guoxin, called the building of the open house a 'third-generation sports building'. At present, there are more than 10 large open and closed roof structures in the world with more than 10,000 square meters.
Zhejiang jinggong steel construction group has successfully applied the technology to the exhibition center project of nantong city, jiangsu province. The stadium was completed in May 2006. It is the first all-weather stadium with open closed roof in China, and it is in good condition for the use of the stadium and the opening and closing of the roof. After the completion of the project, the relevant technology has been directly applied to the 2008 Olympic tennis stadium - the open and closed top of the tennis court of the Olympic tennis court, and the stadium project of the national fitness center of dongsheng district, erdos.
Recently, we interviewed the engineer of the engineering department of the engineering department of jinggong steel construction group, and learned about the problems related to the comprehensive technical research of open closed roof system. To can open closed roof system the working principle of the integrated technology Liu Haisong engineer said: 'can open closed roof system by large hydraulic hoist more traction roof make the open and close of the event, activity by the installation of the roof is present owner car on arch rib support, in under the control of the central control computer, the winch tow car to make it to complete the main arch rib orbiting roof to the centre fold or on both sides to expand, and in the process of moving, according to the relative design stadium arch height and the size of the left and right deviation, move and adjust the support before and after the car around the position and height, ensure the smooth opening and the sliding roof safety of the whole structure of the stadium. '
It should be said that open closed roof system technology is feasible. It is understood that since the 1950s, the structure of open and closed housing has been introduced in small opening and closing structures. From 1950 to 1988, the folding membrane was used to open the roof structure; The rigid mobile roof covers the structure of the unit. Way of opening and closing of the movable roof structure can be divided into: the level movement, horizontal rotation movement way, the space moving mode, moving around the pivot mode, folding movement way, the combination of mobile. When asked about in the open means of so many, can open closed roof system integrated technology key what is the cause of the premise, Liu Haisong says, can open closed roof construction is different from other building system is the core issue of mobile roof can safe, stable and lasting operation, to ensure the realization of the function of corresponding construction. Because can open closed roof structure system in architecture is a building project and mechanical control system integration, has been built on international open closed roof construction, because good to coordinate the relation between untreated, thering is no lack of to operating difficulties, poor durability due to open and close function is lost. So open closed roof system integrated technology is to deal with the coordination and cooperation between the two systems, from the architectural, structural, mechanical, control, production and installation of technical breakthroughs in multiple dimensions.
When it comes to the difficulty and application value of the key technology of open closed roof system, lu haisong said that the technical difficulties are the adaptability of the control system and the open and closed system. The large-diameter two-cylinder multi-point drive hoist, the transverse adjustment and the longitudinal adjustment technology of the open-closed walking support platform, the precision control of the large diameter steel pipe bending and the production technology of the complex intersecting node. Can open closed roof system integrated technology application value, first of all, open and close the top building is easy to maintain the union of man and nature, improving the efficiency of building houses, avoid closed-end structure particular season need energy to maintain physical activity of a new kind of architectural style. Opening and closing of the realization of the function of the roof construction, especially the opening and closing part of the safe, stable and lasting operation, need structure - mechanical - control of each subsystem in keep its reliability and highly collaborative and the overall system reliability, therefore is highly technical content in the contemporary architecture of a system. The application of this comprehensive technology has promoted the utilization and development of the comprehensive technology of building - structure-material - mechanical - signal and control.
In recent years, with the augmentation of the national or regional economic strength, the citizens of the improvement of sports participation, and can open closed roof technology perfected, some large-scale opening structure built produced very good economic and social effect, the market is getting better and better. As a strong enterprise in the industry, jinggang steel group will further research on the technology of open and closed roof, and make new contributions to the diversification, humanity and modernization of large-scale public buildings.
