Variable cross-section cast-in-place box girder supporting system and construction method
The invention relates to the technical field of box girder construction facilities, in particular to a variable cross-section cast-in-place box girder supporting system and a construction method, and solves the technical problem that the variable cross-section construction efficiency is low due to the fact that the configuration of a supporting system in the prior art is too complex. A group of wing foot adjusting mechanisms are arranged on one side of each group of height templates; the wing foot adjusting mechanism can be detachably connected with a height inclined plate and an extension wing plate, the height inclined plate can be in lap joint with a height template, and the extension wing plate can be in lap joint with a wing part template; the angle can be preset through modeling matching, many quality control errors in actual construction are avoided, variable cross-section treatment is achieved, compared with the prior art, time is saved, a supporting system is simplified, and after the steel formworks are spliced, the height of the wing end of the box girder can be adjusted according to different preset ranges. Therefore, the height from the wing end to the platform body is changed.
本发明涉及箱梁施工设施技术领域，特别涉及变截面现浇箱梁支撑系统及施工方法，解决现有技术中的支撑系的配置过于复杂，导致变截面施工效率低的技术问题，本技术方案中翼脚调整机构作为控制实际的箱梁翼端的曲率的机构，每组高度模板的一侧布置有一组翼脚调整机构；翼脚调整机构上能够可拆卸地连接高度斜板和延展翼板，高度斜板能够搭接高度模板，延展翼板能够搭接翼部模板；并且可通过建模匹配预先设定好角度，避免了很多实际施工时的质量控制失误，且实现变截面处置，相比较于现有技术，不仅节约时间，也精简了支撑体系，当钢模板拼接完成后，箱梁翼端的高度可依据预设范围的不同，以改变翼端至平台体的高度。
