摘　　要：利用桥梁工程中无支架摩擦抱箍法施工工艺对框架结构进行加固,可以在不影响使用的前提下,解决框架梁的加固问题。详细讲述了该加固方法的工艺原理、工艺流程及操作要点。该方法受力明确,设计计算简单,施工方便,在某搅拌楼加固工程施工中得到很好验证。The prestressing friction support and holt hoop iron construction technique which is developed from bridge engineering is used to strengthen frame structure. The method can solve the strengthening difficulties of frame b^ams without disturbing their work. The process theory, construction process and operation key points for this strengthening method are introduced in detail. This technique has many merits including explicit loading, simple design calculation and convenient construction, and the strengthening effect is confirmed in a building strengthening engineering.
