浅谈如何提高地铁车站盖挖逆作钢管柱与纵梁节点钢筋施工合格率

Discussion on How to Improve the Qualified Rate of Rebar Construction of Steel Pipe Column and Longitudinal Beam Joint with Cover Excavation in Subway Station

地铁地下车站各道主梁与钢管柱之间连接通过加强节点连接,节点钢筋绑扎、连接质量关系到车站能否整体受力,是盖挖逆作车站质量、安全控制的核心内容。与明挖车站梁、柱节点处理存在很大差异,节点钢筋设计复杂、分布特殊、层次较多、纵横交织、施工困难。论文主要介绍了提高地铁车站钢管柱与纵梁节点钢筋施工合格率的应对措施和方法。

The connection between each main beam and steel pipe column of underground subway station is strengthened by node connection.The quality of joint rebar binding and connection is related to the overall stress of the station,which is the core content of the quality and safety control of the cover excavation of reverse station.There is a great difference between the joint rebar and the open-cut station beam and column joints,which is complicated in design,special in distribution,multi-level,crisscross and difficult in construction.This paper mainly introduces the measures and methods to improve the qualified rate of rebar construction of steel pipe column and longitudinal beam joint in subway stations.
