摘　　要：钢梁部分的加工和装配施工是整个钢箱叠合梁建筑工程中的“两朵乌云”,给整个项目施工过程带来了很大影响。钢梁构件的生产加工、转移、装配和施工监控是十分关键的组成部分。文章结合康庄大道高架桥钢叠合梁的安装,对临时支架设计、临时支架卸载施工工艺技术内容进行了探讨和实践,阐述了钢叠合梁支架法施工的要点工艺技术。The processing and assembly construction of the steel beam section is the“two dark clouds”in the entire steel box composite beam construction project,which has had a significant impact on the entire project construction process.The production,processing,transfer,assembly,and construction monitoring of steel beam components are crucial components.The article discusses and practices the installation of steel composite beams for the Kangzhuang Avenue elevated bridge,including the design of temporary supports and the unloading construction technology of temporary supports.It also elaborates on the key process technologies of the steel composite beam support method construction.
