Large Span Steel Structure Installation Process Overall Lifting Technology Research And Application

At present,China's economy continues to develop,and China's construction industry under the influence of China's economy has also been improved,large span steel structure plays a very important role in the construction industry,therefore,are constantly developing.China's construction industry in the current market,many large and complex,and overweight steel and its main components are applied in many projects is very wide,so in order to adapt to the current rapid development of the construction industry in our country,it is necessary for large corresponding span steel structure construction technology of some degree of improvement and innovation.In recent years,large-span steel structure construction technology in the development of the overall jacking up in construction has also been widely used,but also steel construction technology is a new type of installation process.This construction technique not only to meet the corresponding requirements of large-span steel structure installation works,but also the development of China's construction industry,modern technology has a very important role.The main analyzes and studies the construction process for the installation of large-span steel structure often used,such as fold expansion method,the method and the overall block hoisting lifting methods,and so this article.And also some projects for the corresponding analysis and research.Analysis of the overall jacking construction technology were the status quo and introduce concrete construction methods,and the arrangement of its main methods,calculation methods and control methods,and so do the corresponding research,but also in the construction of its process problems generated by the corresponding analysis,this paper further demonstrates the major role of its research.
