The Quality Control And Supervision Of The Large Span Space Tubular Truss For Tuanbo Stadium

The character of large span space tubular truss structure is that it has a complex three-dimensional space joint, connecting member and more tube intersecting joint welding. This structure requires high precision, high welding quality design, with many processes and complex technology standards. it is difficult to manufacture and install because installation force structure changes in many states and different stress state will occur in different conditions during the installing process. Safety and reliability during the lifting and installation should be ensured. Accuracy should be ensured as well. Quality of works should be ensured. No safety accidents are allowed to occur in the project. It is very essential to do a deep research on the installation quality control and supervision.As the shape, selection of structure, span size, construction site, duration, conditions of construction of large-span steel are different, the installation methods also vary. There is no proper experience to control the project quality. Based on the solution of the installation quality control problem in Tuanbo Stadium, this paper researches and introduces the important points of the large span space tubular truss installation quality control measures and supervision. The article focuses on large span space tubular truss production quality control measures and supervision. It also focuses on the Steel lattice tower rectangular steel pipe concrete box column production, lifting quality control and supervision, as well as the key points of the control and supervision and management of the tension cable and other aspects.Various elements of construction quality control and supervision this article explored have been successfully applied in the Tuanbo stadium project. Through practice, these elements provide valuable experience rate for the same type of large span steel Truss structural engineering supervision and management. And we have concluded a set of quality control points and supervisory methods for large span space steel structure. These methods have reference value for similar projects.
