With the rapid growth of Chinese economy, super high-rise building has developed rapidly. In recent years, the integral steel platform system for super high-rise building the core tube structure is a new construction technology, in a number of high-rise building projects have been applied. It through a steel beam consisting of a steel platform scaffold connecting, closed all the operating environment, using setting in concrete cylinder strength character columns bearing, electric elevator lifting, core tube wall inside and outside the overall template is arranged in the steel platform, the integral steel platform formwork system only needs to install once. It varies with the construction by layer self lifting, improve working environment with fast, safe and reliable, convenient construction, concrete engineering quality assurance, remarkable economic benefit and a series of advantages, is worth popularizing super high formwork system.This article take the Guangzhou new TV Tower project as the background, the integral steel platform system construction key technology research. In 335 ~ 376.6m bid section belongs to the weakest, the alien or other uncertain factors to affect the installation accuracy deviation. As the project is special, we are unable to use the conventional approach to the normal direction deformation constraint, therefore, we can think of other ways, by selecting the number of SRC columns normal direction support to control the overall deviation of steel column. Selection have been pouring platform for supporting role, as far as possible: ( 1), the support rod to avoid the pouring platform; ( 2), supporting rod and the rigid column effect point to the template layout.Steel platform aerial split is the project of another construction difficulties. Decomposition of steel platform is unconventional means, specifically how to decompose, in a nutshell, each project based on its engineering characteristics of decomposition. If the decomposition in the top of the structure, modification of the amplitude can be amplified, as modified after use can be removed, does not need to be changed back to the original standard way; otherwise, it is necessary to consider the energy can. In Guangzhou new TV Tower at the top of the construction, steel platform is made larger scale change. According to the actual conditions of the project, 2 solutions are proposed: ( 1) no longer climb steel platform ( 2) steel platform air split. Comprehensive comparison of two schemes, decided to adopt the steel platform air split scheme.At present, the market competition is becoming increasingly fierce, the construction cost pressure continued to grow, how to do template and scaffold system saved steel consumption, environmental protection and energy saving construction process, to create a safe, efficient construction platform is a problem. In order to solve these problems, according to the actual engineering problems encountered in the construction, the integral self-lifting steel platform formwork system to carry out research, aims to design a safety is most reliable, reasonable structure, economic and efficient construction platform.
