Construction Technology Of Climbing Formwork For Super High-rise Building With Core-tube Structureand Its Efficiency

Super high-rise buildings were born due to remarkable economy benefits, and become more and more popular since the enormous socialefficiency. Many enterprises compete for construction of high rise buildings to display their wealth and social status. In the process of the construction of high building, developers require shortening time limit for a project, sales as soon as possible, in order to accelerate the capital turnover, guarantee rate of capital return;construction unit must have to speed up the construction progress, improve construction quality, in order to meet this need, and to improve the competitiveness of the market. Of high-rise is concerned, climb and application mode, to great down the project construction period is possible, from the current technical level of the industry, for the high-rise building of the climbing formwork technology research and explore very necessary and timely.The significant characteristics of formwork climbing is the repaid climbing speed, convenient operation, simple structure, good overall stability, high safety coefficient for high-altitude operation, excellent engineering safety and quality assurance. The climbing formworks normally are not transported back to ground for turnover once they are assembled until the top of the building. In doing so, the construction plant is saved, bruising damage of the templates is reduced, and the turnover frequencies of template panel are increased. At the same time, an all-directional operation platform is provided, and the construction materials and labors required to reconstruct the platforms are decreased. But the country involved in climbing modes to the core technology is not comprehensive, especially the node design consideration is not careful, involve climb node module design factors consideration is not comprehensive, climbing formwork of risk management is not in place and widespread does not match the phenomenon exists in rapid construction of vertical evacuation channels and climbing formwork.In this paper we mainly use the research methods of case analysis and proof, and put forward the principle of selection of high-rise building construction in climbing formwork system in the design process, by comparing the advantages and disadvantages of different climbing formwork system analysis, combined with the structural characteristics of the Shenzhen Ping’an Mansion, determined by climbing formwork system, and the Shenzhen Ping’an Mansion construction for example, the climbing formwork node design related aspects of the core tube, with practical engineering as the foundation, put forward the principle of selection of high-rise building construction in climbing formwork system in the design process, and to the solution of nano super tall climbing encountered difficulties in the construction process of the case, to provide reliable for similar high-rise building the design and construction process of climbing model system. The key factors of the risks associated with climbing formwork encountered in the actual operation process of are analyzed, and puts forward the concrete solution; combined with the structure characteristics of super high-rise building and climbing formwork design, research and discusses the climbing formwork system for vertical transportation system design problem. In the process of climbing the mold, the management must be put in the most important position.
