Key construction techniques for overall assembly and lifting of the three-dimensional truss structure system
Taking the three-dimensional truss structure roof of an airport as an example,this article analyzes the key technologies for over-all assembly and lifting construction.A detailed introduction was given to the construction processes of overall assembly,overall lifting,in-stallation of supporting steel columns,and dismantling of tower columns.Combined with finite element analysis,the stress,deformation,and concrete bearing capacity of the steel structure during the overall lifting process were verified and analyzed,and the acceptance results of each parameter met the requirements of relevant specifications;At the same time,key points for improving process monitoring were provided for the key and difficult points of this project.This case can serve as a reference for similar structural construction in the industry.
