Study On High Strength Bolt Test And Construction Of Zengjiayan Bridge Steel Structure

Along with our country the steady growth of the national economy and the improving of the comprehensive national strength,traffic power has become a national development strategy,and bridge construction to perfect the regional road network,promoting regional economic and social development,improve the image of the area and convenient on both sides of the foundation,significance in such aspects as residents.Therefore,the safety of Bridges is increasingly valued by managers,designers,builders and ordinary people.In the design and construction of modern bridge steel structure,a large number of high-strength bolt sets are used to realize the connection.The connection design of high strength bolt group of bridge steel structure has direct influence on the quality and safety of bridge engineering.Safe and reliable to ensure that the design and construction of the bridge construction,the design must be considered when the mechanical properties of high strength bolt group,the friction force,and many other factors,the application can correct analysis and calculation of the corresponding parameters and variables,the parameter management process can make specific,relevant departments and personnel,effective connection each working procedure,to ensure the safety of bridge construction,reliability,comprehensiveness and integrity.In this paper in order to pay the second shipping bureau Ceng Guyan bridge construction second engineering co.,LTD.,construction of chongqing as an example,combined with the author's working practice,put forward the research background and significance of the paper,on the basis of summarizing the research status quo,put forward the research content of this paper.By the high strength bolt connection system,work principle,performance and technical requirements,analyzes the factors influencing the construction quality of high strength bolt,including construction process,purchasing and storage,receiving and necessary,combined with the treatment,the connector assembly,etc.Focusing on high strength bolt connection Ceng Guyan bridge construction plan,bolt group of experimental research and quality acceptance,are discussed and the application analysis,so as to provide reference for relevant bridge construction.
