分体悬挂式移动模架造桥机技术方案研究

分体悬挂式移动模架造桥机的分体是指主机体系和过孔导梁体系分开,悬挂则是指主机体系的前后支点为悬挂支撑方式。主机主梁通过后吊架的悬挂支撑在已造梁的梁端,吊架横梁有斜撑杆支撑,主机前点通过前吊架支撑在墩顶垫石上,导梁则直接放置在墩顶。介绍了各部件的结构、功能、安装与施工工序和支撑、扭矩控制、脱模、过孔、首末孔施工等关键技术。分体悬挂式移动模架造桥机能够很好的满足原位高效、高质量造梁的需要;结构简单明确,受力性能好,不用在墩身提前预留施工,整机重心低,稳定可靠。

Study of the Technical Plan for the Separately-suspended Movable Frame Bridge-maker

By the separately-suspended movable frame bridge-maker,we mean that the system of the main body of the bridge-maker is separated from the system of the span-crossing lead beam,and that the front and hind support points of the main body system are suspended.The main beam of the main body of the bridge-maker is supported at the end of the finished girder by means of the suspending supports of the hind lifting frame,the lateral beam of which is supported with the diagonal braces,the front point of the main bod...
