A Large Span Steel Truss Construction Technology Research At The Stadium

With the improvement of China’s comprehensive national strength and the rapid development of construction industry, large-span space steel structure is in rapid development period, all kinds of large, complex, overweight steel structure and steel structure has been widely used in engineering, is followed by a large steel structure construction technology development and corresponding innovation, large-span space steel structure construction technology of the ascent of the whole is gradually developed in recent years in the construction industry in our country, a new type of steel structure installation technology. This technology adapted to our country for the development and application of large-span space steel structure installation of the new technology needs, to speed up the modernization of our country has very important practical significance.In this paper, combined with engineering example, a long-span steel truss to steel structure construction hoisting technology in our country at present the development as the background, on the basis of the related literature review, of a long-span steel truss construction hoisting technology has made the analysis and research. Paper main research contents are as follows: in the existing steel structure at home and abroad,based on the present study for complex steel structure construction stage, combined with the specific project, further study on its installation. First introduces the general situation of the engineering basic construction overall train of thought, and expounds the method of bottom assembled steel truss and concrete technological process, and use the 3 d model of truss assembly process simulation in detail on the ground; Then the installation process brace and the layout of the transfer beam has carried on the detailed design analysis as well as to the roof hoisting after unloading process in detail in this paper, the; Secondly the construction process of steel truss structure calculation analysis, verify the feasibility of the construction; The last of this engineering construction survey and steel truss construction monitoring is discussed in detail.Through this project of steel structure engineering construction hoisting technology research, help us to deepen the construction of large span steel structureengineering lifting technology, but also for the future of the big span steel structure engineering construction is of certain reference significance.
