With the recent large-span building in our wide range of applications , the appropriate construction techniques and technology has been rapid improvement and development . In this paper, the construction technology matures summarized theoretical , technical issues relating to explore further analysis , in order to promote the application of advanced process engineering methods to improve the technical level of construction enterprises and the overall industry technology content. Firstly, from the meaning of the concept of large-span structures start with a brief introduction of the common forms of large-span structures , commonly used materials , development and application . Combined with large-span steel structure of the various forms , such as flat trusses, truss , shell , etc., discussed the general outline of the construction method , processes and techniques , including the overall lifting method , the overall jacking method, enhancing the overall method, altitude bulk method , sub-unit method and the lifting height sliding method . Second, commonly used for large- span steel truss system , devoted to its form , materials , construction, and China's current development . A common space for the current truss system , discuss Sliding Construction of the truss , more systematic exposition of the method of construction of slip lifting and transport solutions , construction layout, structural assembly, transportation, stacking and cell division , rail system layout , track settings, tire architecture made ??, traction control , and many other equipment and process problems . Then one of the key issues for further discussion, including a summary of Sliding process ; tire rack on the selection of reference scaffolding calculations, the use of specifications, software programs , three methods of analysis of characteristics , with the existing scaffolding comparative analysis of test results , arrive at a more realistic tire rack capacity value ; slip process for automatic control and dynamic and static control monitoring has made application analysis and theoretical discussion . And use the above theory, discusses the construction of the airport in Shenzhen slip France ( structural slip ) , Shenyang Airport ( tire rack slip ) and other major engineering application typical example .
