结构改造设计既要保证改造后结构的安全,又要尽量减少改造工程量,方便施工。通过对某度假村结构改造抽柱增设托架的工程设计和施工实例,在保持原有结构基本不变的情况下,采用在拟抽柱两侧增设钢托架的改造设计方案及在施工时通过在托架上架设千斤顶顶升原有结构的施工方法,顺利地完成了原有结构抽柱改造增设托架的工程实践,取得良好的改造效果,并总结结构改造中托架的设计和施工要点。

The design of reconstruction of a structure should not only guarantee the safety of the structure, but also minimize its modified quantity, as well as for the convenience of construction. Through the design and construction of extraction column for additional bracket to reforming the structure of a holiday village, it was introduced in detail the design scheme of maintaining the original structure, by adding： steel brackets on both sides of quasi columns and the construction method Of jacking up the original structure by the jacks on the bracket, with which the reform of the structure was completed smoothly.
