Study The Safety Of High-Formwork And Supporting System From The Girder Structural Transition Layer

With the development of economy, more and more high-rise buildings and super high-rise buildings being built in cities, and their combination property being requested more and more strong, thus, the structural transfer floor will play an important role in them. Because of large load being transferred to the structural transfer floor, in fact, it requires a great deal of steel and high strength concrete to meet its bearing pressure and integral strength requirement in the design for the structural transfer floor. Therefore, the difficult will be existed in the construction process of the structural transfer floor. At the same time, high-formwork system as a temporary structure, make sure that its bearing pressure and integral stability meet requirements in the construction process. Generally speaking, the main job in this paper is that design accurately and calculate the safety of the high-formwork system.In this paper, the engineering background of the Yunding project from Blue ray corporation in Chengdu city, analysis the safety of the beam type structural transfer floor, and use the following ways, theoretical calculation method, numerical simulation method and the real-time monitoring method. There are four parts researched in this paper.Firstly, this paper analysis the accidents of the formwork support system, and make some important reasons and conclusion to provide the experiences and lessons for the construction in the future.Secondly, the theoretical calculation is mainly based on standard JGJ130-2011, and at the same time, puts forward the norms of the deficiencies, and give some advice on the theoretical calculation through the basis on scholars’researches.Thirdly, in the numerical analysis, this paper first and foremost uses the finite element software ANSYS modeling in order to analyze according to the actual situation of the layout, and then analyzes the numerical simulation according to the implementation of the program in the theoretical, and last makes two improvement schemes, in order to present some suggestion in security, human, financial and material resources for reference.Fourthly, the information technology is used in the construction process in order to get real-time tracking monitoring of temporary high formwork system to ensure the safety of the construction process and provides an important reference for the similar projects through the field monitoring data analysis in order to the safety prediction of the construction.
