The Expreimental Study And Theoretical Analysis Of The New Cable-stayed Suspended Formwork Support Design

Recently, with the continuously development of china’s economic and social level,the requirements of people for buildings not only must be living and office, but also forarchitectural appearance, shape and adapt to the environment also put forward higherrequirements. With this trend, various architectural forms constantly emerge, whichcontain large cantilevered structure cantilevered building is one of the common forms.Since the construction of large cantilevered structure is often required features inhigh-altitude operations, at present, for high altitude large cantilevered structure designand construction experience are relatively small, so, high-altitude large cantileveredbuilding design and construction process also exist many difficulties. Such as the designof cantilever forms, construction of Cantilever Structure. This paper summarizes thecommon type of cantilevered scaffolding at present and put forward New Cable-stayedSuspended Formwork. A practical engineering is taken as the example to test and verifythis theory and put it into practice. The specific contents are as follows:First of all, it analyzes the advantages and disadvantages, applications ofcantilevered scaffolding, and Stress analysis of cantilevered scaffolding. Comparativeanalysis each component affected by the force of different oblique position on largecantilevered scaffolding and gives the large cantilevered scaffolding Cable-stayed pointslocation determine formula. It forms a New Cable-stayed Suspended Formwork.Secondly, it analyzes the global stability of the New Cable-stayed SuspendedFormwork which applied to large cantilevered structure, and put forward the wholesupporting system arrangement principle. In addition, it also studies the balance force oftension diagonal and relevant node, and carries out a balanced force ConstructionControl Study.Thirdly, it makes out a influence analysis of concrete structures which is effected bythe tension Diagonal. It mainly analyzes the effect of concrete beams when the buryingangle of tension diagonal is changed, and proposed dimensions, reinforcementrequirements for concrete members and other basic requirements.Finally, according to the above research, it gives the design structure and construction requirements for the New Cable-stayed Suspended Formwork, Forming aset New Cable-stayed Suspended Formwork systems which is used to high-altitudelarge cantilevered building.
