Leveling control method for slideway plate of old slideway beam
The invention discloses a leveling control method for a slideway plate of an old slideway beam, relates to the technical field of bridge construction, and solves the problem of high leveling difficulty of the existing old slideway plate in a limited space, and the leveling control method comprises the following steps: after high-strength bolts and welding construction of a slideway beam butt joint port are finished, finding out a slideway plate shoveling pad reference point; padding; after the cushion meets the requirement, the slide way plate is pre-pressed through a pre-pressing device; finishing the padding of all the slide way plates of the truss; after measurement and rechecking of the single-truss slideway plate are completed, slideway plate butt joint port welding seams and slideway plate two-side welding seams are symmetrically welded from the middle to the two ends, lifting lugs and limiting stop blocks on the two sides of the slideway plate are cut off, and welding slag on the surfaces of the slideway plate and the slideway beam is polished; according to the invention, the slideway plate of the old slideway beam is transported, adjusted, measured, cushioned, pre-pressed and welded through the slideway plate hoisting and transporting trolley, the pre-pressing device and elevation control, so that the purpose of accurately leveling the slideway plate is realized, and the device has the advantages of simple structure, convenience in manufacturing, good applicability, simplicity and convenience in operation and the like.
本发明公开了一种利旧滑道梁滑道板的调平控制方法，涉及桥梁施工技术领域，解决现有对利旧滑道板在受限空间下进行调平难度大的问题，包括当滑道梁对接口高强螺栓及焊接施工完毕后，找出滑道板抄垫基准点；抄垫；抄垫至符合要求后，用预压装置对滑道板预压；完成本桁所有滑道板的抄垫；完成单桁滑道板测量复核后，从中间向两端对称焊接滑道板对接口焊缝及滑道板两侧焊缝，割除滑道板两侧吊耳及限位挡块，打磨滑道板及滑道梁表面焊渣；本发明通过滑道板起吊运输小车、预压装置及标高控制，对利旧滑道梁滑道板进行运输、调整、测量、抄垫、预压及焊接，以实现滑道板精确调平的目的，具有结构简单、制造方便、适用性好、操作简便等优点。
