南京色织厂某框架厂房加固改造设计与施工

Reconstruction Design and Construction of Reinforced Concrete Frame Structure Factory Building in Nanjing Yarn-dyed Fabric Mill

南京色织厂某框架厂房将被改造为大型展览馆,加固改造后的框架厂房需满足新的功能要求和结构安全要求。为了解老旧框架厂房在功能和结构发生改变后应采取的对策,本文结合南京色织厂某框架厂房加固改造实例,讨论了钢筋混凝土多层框架厂房在抽柱和加层改造时应考虑的若干关键问题,包括检测鉴定、计算分析、基础加固、混凝土构件加固及抗震构造加固等,介绍了一些有效的解决办法,可供同类建筑物加固改造参考。

The reinforced concrete frame structure factory building in Nanjing Yarn-dyed Fabric Mill will be reconstructed to a large exhibition building.The reconstructed building should meet the new functional requirements and the structural safety requirements.In order to obtain the treatment measures for the old factory building with the function and structure changed,based on the strengthening and reconstruction project,some key problems in removing columns and adding stories design of the reinforced concrete frame structure are discussed,including methods of testing and appraisement,computing and analyzing,foundation reinforcement,concrete members reinforcement and seismic reinforcement,etc.Some effective methods are introduced to solve the problems,which can be referenced for similar designs.
