自承式楼板在地铁车站逆作法混凝土结构中的应用

Study and Application of Self-supporting Floor Used in Subway Station Constructed by Concrete Structure and Top-down Method

地铁车站逆作法施工中的部分夹层板墙采用不同满堂脚手架搭设的支模架存在着材料运输困难,模板无法拆除等问题,给结构施工带来了较大不便。通过调查研究采用自承式模板支撑技术,上述问题可得到很好的解决。自承式楼板技术在逆作法施工的地铁车站中具有施工方便、操作简单、速度快、受力合理、省工省料等优点。

when using top-down method to construct subway station, the project would meet some problems existing in some sandwich plate walls, those problems were resulted from the adoption of different full-hall scaffolds for erecting supporting framework, such as the materials were hard to be transported, the framework cannot be demolished, and has been a relatively big inconvenience for the structure construction. However, according to investigation and research, those problems mentioned above could be well figured out by using the supporting technology of self-supporting framework. Self-supporting floor plate is convenient for construction, simple for operation, quick for construction, which is of rational stress and less need for laborers and materials.
