New technology boosts the steel structure market to usher in a new spring

Recently, Dr. Liu Hang, deputy chief engineer of the Beijing Institute of Construction Engineering and director of the research center, presided over the Beijing Municipal Engineering Research Institute and Beijing Machinery Construction Company to participate in the completion of the first green channel project of the Beijing Municipal Science and Technology Commission and the Housing Construction Committee. The key technology of structural construction was tackled and won the first prize of Beijing Science and Technology.

The key technology of complex steel structure construction was established in 2005. After three years of practice, it passed the expert appraisal in June 2008 and was highly evaluated. Finally, it won the first prize in the Beijing Science and Technology Progress Award. This topic embodies the academic achievements and engineering practice experience of Beijing Institute of Technology in the field of steel structure for many years. The subject has a wide range of radiation and involves many technical problems in the construction stage of complex steel structures. For example, through optimization research on large-scale prestressed steel structure construction technology, design-construction integration is realized; on the basis of ensuring project safety, structural rationality is improved, consumables are reduced, and construction results are consistent with design assumptions. The complete set of deepening design theory and construction technology in the Changzhou Gymnasium project fundamentally solved the construction problem of the string-supported dome structure. For example, through the research on the steel structure tool-type temporary support system, the safety accident caused by the too weak and weak support system is greatly reduced, and the construction cost and construction period are greatly saved. Only one project of the National Convention Center saves 2.9 million yuan and shortens the cost. The construction period is 60 days. The subject also realizes the full-cycle information management of the construction site through the on-site information coding management technology of steel structural members, so that a wide variety of components and a large number of components are always in order. For example, in the Northeast Normal University Gymnasium project, 3,070 of the 3,782 components were systematically managed, which greatly improved management efficiency.

At present, the research results have been successfully applied to the National Stadium Project, which is known as the “World's Largest Span Two-Dimensional String Truss Project”, and the A380 Machine of Capital International Airport, which is known as the “World's Largest Volume Roof Improvement Project”. More than 100 large-scale projects such as the Dongying Yellow River Mouth Simulation Hall, the “first-largest one-story truss truss project in the world”, and the Erdos Gymnasium roof project called “the first large-span cable dome structure in China” Key projects. As far as economic benefits are concerned, “the key technology of complex steel structure construction” is one of the core creators of the economic benefits of the Institute. As far as social benefits are concerned, this project not only effectively improves the construction technology and technical level of large and complex steel structures, but also significantly promotes the technological progress and development of China's steel structure industry, and promotes the new steel structure market. spring.
