The Aluminum Formwork Construction Optimization Design And Engineering Application Of Super High-rise Building

In recent years, with the rapid development of China’s construction industry, in domestic cities, there are some super-tall architectures, they sprang up like bamboo shoots, then there have been several relatively new template system, such as Shenzhen king key100, Canton east tower. Besides, dongguan international financial centre project adopts jumping formwork system.Although template construction cost accounts for only a quarter of the reinforced concrete structure, but it is far greater than the value of labor and time limit for a project. Traditional template material has a wooden template, steel template., bamboo gluing template. A new type of template material contains aluminum alloy template, plastic template, etc. After comparing the various indicators, aluminum template with its light quality, easy to tear open outfit, high bearing capacity, the components are good durability, high turnover, the construction site without construction garbage, strong commonality, high recovery value, etc. These advantages stand out from the numerous templates, widely used in the coastal area of high-rise buildings.To Shenzhen xiasha community reconstruction project as an example, this paper in detail introduces the project of aluminum formwork system design scheme and that achieve the optimized aluminum alloy template design scheme. The optimized design scheme, from the different parts of aluminum alloy template design to the installation of aluminum alloy template, the treatments of special positions. Through the finite element method of MIDAS Gen for aluminum alloy simulated calculation template design. In the process of simulation, mainly considering the aluminum template node connection mode, the design of support system and so on. These provide theoretical basis for the optimized aluminum alloy template.Adopting the method of Similar to the end of the equivalent, aluminum template with the other two templates for technical and economic comparison and analysis, calculating three kinds of template turnover capitation fee. The results display that under the same conditions using aluminum alloy template is more economic. By comparing several super-tall common template system key construction program and economic analysis, conducting the finite element simulation checking, reaching aluminum formwork system than the wood template, steel formwork has more advantages. The study has a broad Application value in the construction of high-rise buildings.
