摘要
某影剧院由于使用功能改变,需要进行抽柱处理。通过分析抽柱对原有结构的影响,对相邻梁柱先进行加固。结合现场情况以及本工程特点,采用预应力管桁架作为托柱转换加固方案,对其加固过程中的管桁架吊装、预应力张拉和抽柱的过程进行施工监控,对大跨度空间的加固改造发展有重要意义,可在类似的工程中运用。最终结果证明了方案的可靠性,整体改造工程顺利进行。
Due to the change of use function,a theater needed column extraction.By analyzing the influence of column extraction on the original structure,the adjacent beams and columns are strengthened first.Combined with the site conditions and the characteristics of the project,the prestressed pipe truss is used as the supporting column conversion reinforcement scheme to monitor the process of pipe truss hoisting,prestressed tensioning and column extraction in the reinforcement process,which is of great significance in the reconstruction scheme of long-span space and can be used in similar projects.The final result proved the reliability of the scheme and the overall reconstruction project was carried out smoothly.
