模板作为墩柱施工的重要系统,是墩柱施工质量、进度、成本和安全的关键影响因素,文中以水盘高速北盘江特大桥高墩悬臂桁式外架钢模板应用为实例,通过对模板体系设置的优化和设计,采用了钢模板配合悬臂桁式外架结合的方式,不仅施工简单灵活、整体刚度和稳定性良好,且具有较好的安全性与经济性,是高墩施工较为理想的方法之一。
As an important system of piers construction, the template is the key influencing factor of pier construction quality, schedule, cost and safety. In this paper, the application of cantilever truss frame steel plate with high piers and high- The optimization and design of the template system has adopted the combination of the steel template and the cantilever trussed frame, which not only has the advantages of simple and flexible construction, good overall rigidity and stability, but also good safety and economy, One of the ideal ways.
