Research On The Construction Quality And Technology Management Of Multi Surface Steel Truss

In recent years, the large complex space steel structure has developed rapidly and widely in our country. Because of its reasonable stress and rigidity, it is suitable for large space and large span building, and it is suitable for the design of various shapes and types. At the same time, the performance of the space steel structure becomes more complex, the surface modeling of a large number of appearance, so that the construction of the difficulty increases, the requirements of the construction of the building also increased. In the process of construction, it is very important to carry out technical simulation analysis and the key point of the whole installation process. Therefore, it can provide experience for the construction of complex curved surface.This paper discusses the planning and process control measures for the construction of complex space steel structure with large scale and curved surface. First, the large hetero space steel structure installation method of analogy analysis, combining Guangzhou Asian Games Gymnastics Hall of curved steel structure installation engineering design characteristics of the whole process of construction installation set ideas, the quality of the installation method can according to the altitude of the original scattered spelling and single element installation method both quality management methods used in combination. According to the engineering quality control objectives and the process characteristics, from the management system, personnel structure, the process control and other aspects of the steel structure engineering installation quality management planning, decomposition for the project quality management and support and unloading and other temporary works of management. Finally, according to the Asian Games Gymnastics Hall of actual construction effect, draw the key technical measures of quality control, the main control points are is processing, such as pre assembled phase measurement positioning, hyperbolic space truss lifting and assembling process control, and combined support frame design make the installation accuracy of support and overall unloading by supporting frame, the structure deformation control.In summary, combined with the large multi curved space steel structure installation process simulation and related installation control technology, the construction organization, quality monitoring and planning of such installation engineering has a key role. This paper has important reference value for the technical quality control of large span multi curved space structure in the future.
