杭州奥体中心主体育场看台顶超高超重环梁支模技术

Formwork Support for the Extra-high and Heavy Ring Beams on the Top of the Main Stadium Stand of Hangzhou Olympic Center

结合杭州奥体中心主体育场工程,详细介绍了环梁结构,超高环梁结构支模体系选择方案,以及钢结构平台支模体系设计。从看台顶环梁结构支模体系的安全性、适用性与经济性等方面考虑,采取搭设钢结构平台,在钢结构平台上搭设看台顶环梁支模架的形式实施环梁支模体系,从而克服了传统支模体系在本工程看台顶环梁结构中应用的不利影响。

Combined with the main stadium of Hangzhou Olympic Center,the authors introduce the ring beam structure,selection of formwork support schemes for the ring beam and design of the steel platform formwork support system.Considering safety,applicability and economy,etc.,it was decided to set up a steel platform,and the framework that was to provide support to the ring beam formwork was then built on the steel platform.This scheme avoided the adverse effects that traditional formwork support system would impose on the ring beam structure.
