The Jackinng Scheme Of A Super Long And Large Span Net Shell Coal Storage Shed

Space steel structure is in the ascendant, especially the Olympic Games and WorldExpo bid is applicable to be held successful, large-span space structures get rapiddevelopment in China. In addition to structural innovations, the space steel structureconstruction technology and construction process, many of the key technical issuesattract more and more attention, the designer should not only pay attention to the designof the state structure,but also to care about its forming process, in order to ensure thesafety and structural construction molding a state to meet the design requirements.In this paper,according to a coking focal field enclosed steel mesh shell coalstorage shed in Handan for instance.According to the analysis of the characteristics ofthe construction project site, difficulty, considering the construction of economy andoperability determine block jacking construction program.The paper focused on solvingthe problem of determining the long span Grid Ceiling liter dry coal shell programs:divide and starting the flow of grid construction unit, optimal layout and checkinglatticed shell jacking frame, the jacking frame design and checking the top l unloadingrack removal program, which is used when the synchronous lifting unit was latticedshell hydraulic synchronous lifting systems. The use of finite element softwaresimulation Sap2000construction process, the installation process latticed shell dry coalshed were mechanical analysis, to solve the network shell rods super stress anddeformation problems that exist in the construction process, Long Span network ofsimilar shells dry coal shed construction has a certain significance.
