[摘要] 該工程新的使用功能需將原結(jié)構(gòu)居中的1根框架柱拔掉。設(shè)計(jì)中采用混凝土框架梁、柱增大截面法，同時(shí)框架梁雙向跨度變大且形成十字梁。施工中遵循“先加固、后拔柱”的原則，首先對(duì)基礎(chǔ)注漿加固，對(duì)梁、柱分別采用水泥基灌漿料、混凝土增大截面，再行拔柱。

Abstract: The construction of new features needs to remove one frame column. The consolidation beam and column design is given by using cross-section increment in the engineer, and extends for the frame beam of the original structure to form cross-beam. Abide by first strengthening then removing the concrete column in construction, first the foundation is reinforced by pressure grouting technology, beams and columns were used cement-based grouting material and concrete to increase cross-section, then remove the frame column.
Keywords: supporting beam;   removing column;  strengthening
