钢结构施工技术在既有结构上拆改、安装中的应用

APPLICATION OF STEEL STRUCTURE CONSTRUCTION TECHNOLOGY IN DEMOLITION,MODIFICATION AND INSTALLATION OF EXISTING STRUCTURES

既有结构地铁停车库上部生根处一般为劲性结构,为确保上盖结构与二次开发住宅户型一致,在结构施工前,要确保一级结构预留的劲性钢框架满足二级开发要求,不满足时,需先进行此部分结构的拆除改造,确保上部结构准确对既有结构的基础传力。

The upper root of the existing structure subway parking garage is generally a rigid structure.In order to ensure that the upper cover structure is consistent with the residential house type of secondary development,it is necessary to ensure that the rigid steel frame reserved for the primary structure meets the requirements of the secondary development.If it does not meet the requirements,the demolition and transformation of this part of the structure should be carried out first to ensure that the superstructure is accurate to the foundation of the existing structure.
