近些年来,在高层建筑设计中,为满足下部大空间要求,通常低楼层设计为大柱网框架体系,上部设计剪力墙、薄壁柱以利于室内房间布置,必将产生竖向构件的转换。在该类项目的实施中,转换层、转换梁的施工将成为项目中一大难点,而转换层的支撑方案选择成为难点中的重中之重。本文以阿布扎比南方阳光酒店项目为例,对转换梁支撑方案进行分析,简要介绍桥梁支架在转换层中的应用。
In recent years, in high-rise building design, in order to meet the requirements of the lower large space, the low-floor design is usually a large-pillar net frame system. The upper designed shear wall and the thin-walled column are favorable for the arrangement of indoor rooms. In the implementation of such projects, the construction of conversion and conversion beams will become a major difficulty in the project, and the selection of the support plan of the conversion layer will become the top priority in the difficulties. Taking the Sunshine Hotel in Southern Abu Dhabi as an example, this paper analyzes the support plan of the conversion beam and briefly introduces the application of the bridge support in the conversion layer.
