摘要
针对昆明新机场航站楼钢彩带支座节点复杂、结构受力大、施工难度大的特点,通过采取深化设计,解决钢筋排布、焊接困难等问题,合理安排混凝土梁钢筋绑扎顺序,采取无收缩高强灌浆料替代混凝土填充彩带支座内空间,解决了钢彩带支座施工难题。重点介绍了支座安装、钢筋绑扎、混凝土浇筑、高强灌浆料等施工工艺。
According to the characteristics of complex joint,large structural force and difficult construction of steel ribbon support in Kunming New Airport terminal,by applying deep design,the problems of reinforcement setting and difficult welding are solved.Moreover,through arranging binding sequence of beam reinforcement reasonably,and using no-shrinkage and high strength grouting material instead of concrete to fill the space of support,the steel ribbon support construction is completed successfully.The construction technologies of support installation,reinforcement binding,concrete pouring and high strength grouting material are introduced in detail.
