The Optimization And Application In The Formwork Of Core Tube Of Super High-rise Building

The tall building general with several standard layer is given priority to, its vertical structure are unified.Especially in the core tube parts which plane geometry is same basically. According to the design scheme, in the middle of the local layer with core tube wall close by, openings, away and other changes. Because in the construction process, consumption amount of work template engineering in the concrete construction the proportion of big. According to these characteristics, the template system will be improved and optimized for the construction stage of the great benefits.Project owner often under capital cost, the income and investment decision problem such as time which decided this type architectural construction pressing time limit. The tall building is more for located in the heart of business type buildings or a city landmark building which construction space relatively narrow, so using a suitable template construction scheme is very important. In the vertical structure similar to the core tube construction, choosing high mechanization degree template construction technology in order to reduce artificial quantity and improve the construction progress, and a perfect a series of system equipment to ensure the safety of construction, the construction site and with reduced control in the construction quality.In ultra-high buildings, the present stage has expanded use of technology is hydraulic climb template technology, hydraulic sliding mode technology, slip-framed reverse mould process, and, in2009, shenzhen JINGJI project successful use less of the fulcrum hydraulic roof up template new technology and so on. These techniques in domestic development and promotion of construction template technology ascend to a new level. This essay, from the current stage of the template technology pick out two representative construction processes are analyzed and compared, and take practical scheme for example and choose the most suitable template construction scheme. To climb mode and the complete set of system, the model using conditions, construction difficulty degrees, the situation of use and economy, construction quality, safety, time limit on consideration, finally selected a the most suitable template system solution.Climb the template system consist of the template system and the power system.Some of the strength of the strength to use core tube as templates support, the template along the wall climb up and climb in the process to have the template turnover; Roof up by the power system, control template of system, support system, steel truss, rack system platform, template and other components of the system, the support of the lower pole the template can be up to three layers of the concrete of the powerful reserve, through the hydraulic power system roof up template. Because of high strength concrete of the end of a long time, using the turnover of template model construction need is bad, the time limit and Labour have certain effect.This paper will take the actual project as the example, for the template system design, with the aid of SAP2000system structure optimization and the analysis of jack-up template the whole system optimization design, find out the best design.
