Steel truss suspension bridge split bridge floor jig frame device and manufacturing method of steel truss suspension bridge

The invention provides a steel truss suspension bridge split bridge floor jig frame device and a manufacturing method of the steel truss suspension bridge, the steel truss suspension bridge split bridge floor jig frame device is adopted for positioning and adjusting tailor-welding assembly of an overall bridge floor, so that the size of the overall bridge floor which is subjected to tailor-welding assembly is accurately matched and corresponds to the size of a main truss frame which is manufactured in advance and measured, and manufacturing of the steel truss suspension bridge is achieved. The structure is simple, installation is efficient, and the main truss frame and the whole bridge floor can be accurately matched, positioned and installed. 提供一种钢桁悬索桥分体桥面胎架装置及钢桁悬索桥的制作方法，采用钢桁悬索桥分体桥面胎架装置定位并调节整体桥面的拼焊组装，使得拼焊组装好的整体桥面与预先制作并测量好的主桁框架的尺寸精确匹配对应，实现钢桁悬索桥的制作。本发明结构简单，安装高效，主桁框架和整体桥面之间可以精确匹配定位安装。
