上海21层大名饭店是采用外承式大模板新工艺施工的。实践证明,这种大模板体系具有很多特点,能适应内外墙全部现浇的剪力墙或框架——剪力墙结构体系的高层建筑的施工要求。因而为高层建筑中发展工业化现浇工艺增添了新的内容。本文概述了外承式大模板体系的特点、设计方法、施工工艺及其与结构设计的关系,并对大模板设计的荷载取值及刚度要求等问题进行了探讨。
21-storey hotel in Shanghai is the use of foreign-style big template new technology construction. Practice has proved that this large template system has many features that can adapt to all external wall cast-in-situ shear wall or frame-shear wall structure of high-rise building construction requirements. Thus adding a new dimension to the development of industrial pouring processes in high-rise buildings. This paper summarizes the characteristics, design methods, construction techniques and the relationship between the design and the structure of the large formwork system. The problems such as the load value and stiffness requirements of the large formwork design are also discussed.
