Assembling method for assembling variable-span girder of bridge girder erection machine
The invention discloses an assembling method for assembling a variable-span main beam of a bridge girder erection machine, and relates to the technical field of bridge girder erection machine main beam assembling. A web connecting plate A, a web connecting plate B and a cover plate connecting plate are drilled through a first hole method, so that the machining precision and interchangeability of holes are ensured; the newly-added sections are inserted into the gaps of the sections on the two sides for splicing, and the splicing is simple, rapid and convenient. The newly-added sections are drilled according to the original bolt holes in the disassembled side, after the span of the assembled beam is changed, it needs to be guaranteed that the camber is smooth, meanwhile, it can be guaranteed that the bolt holes in the connecting positions of all the sections are matched with the bolt holes in the corresponding cover and web connecting plates, and the newly-added sections can be disassembled during disassembly. And the manufacturing precision of the variable-span assembled beam is improved, and the assembling difficulty is reduced.
本发明公开了一种架桥机变跨径主梁拼装的组立方法，涉及架桥机主梁拼装技术领域，采用先孔法对腹板连接板A、腹板连接板B、盖板连接板进行钻孔处理，确保孔的加工精度及互换性，拼装时，将梁整体分成奇数个节段，新增节段插入两侧节段缝隙中进行拼装，简单、快速、便捷。新增节段根据原有拆开一侧的螺栓孔为基准进行配钻，改变拼装梁跨径后既需要保证了拱度圆顺，同时又能确保各节段连接位置处的螺栓孔与对应的盖、腹板连接板上的螺栓孔相匹配，拆除时，拆卸新增节段即可，提高了变跨径拼装梁制作精度，降低了组装难度。
