Key Technology Research And Application Of Large-span Space Shaped Steel Structure Construction

In recent years,with the rapid development of our country's economic construction,construction industry vigor and vitality of the hitherto unknown.The construction industry system is constantly updated,the building structure is becoming more and more complex,the space span is more and more big,which for the engineering construction put forward more stringent standard requirements.In the construction process,the spatial structure will be with the stress state and structure change constantly,in the process is very prone to a dangerous situation.Therefore,it is necessary adopt reasonable design methods,so as to ensure the scientific and reasonable spatial structure,to avoid the construction of spatial structure produce adverse effects.Therefore,it should be strengthened to the construction technology of systematic research,to ensure the reasonable design of the building structure and scientific construction.Spatial structure has its own characteristics,such as reasonable force,lighter weight,lower cost,flexible form.Therefore,many countries in the world of the technology is very popular,which also contributed to the development and application of the technology.In the construction process of space structure,many by force factors mutual co crosslinked in the construction process of space structure influence,construction process of facing new challenges,and Study on space structure construction is still exists serious shortage,so we should strengthen the study on the technique system of.This paper will take the Shenyang New World Exhibition Center project as an example,the construction technology of large span space profiled steel structure is discussed.The main purpose of this paper is through the research and application of typical large span special-shaped steel structure construction technology,summarized the current technology development of this type of steel structure construction and construction methods,and then according to the project specific characteristics,puts forward the key construction technology,and the development and innovation,formed the design technology,deepen steel the structure of super high inclined lattice column step and installation technology of large span steel truss hoisting deformation simulation.analysis technology and low temperature thick plate welding technology for the characteristics of large span space steel structure shaped key construction technology,to enhance scientific and technological research and development ability of enterprises and the construction management level,so as to enhance their productivity and competitiveness,promote the domestic construction the development and progress of steel structure.In this paper,the engineering case based on the specific analysis,with some practical value,hope to provide some reference for the relevant engineering projects.
