Bracket-free construction method for wet joint of small box girder prefabricated anti-collision wall
The invention relates to a bracket-free construction method for a wet joint of a small box girder prefabricated anti-collision wall, which is characterized in that a fixed steel template is arranged on the anti-collision wall prefabricated at two ends and comprises an inner side steel template, an outer side steel template, an upper opposite-pull rod and a lower opposite-pull rod; before construction, the anti-collision wall and the small box girder are hoisted to the bent cap through hoisting equipment, then bridge deck cross beam construction is conducted, and bridge deck structure system conversion is completed; during construction, anti-collision wall wet joint steel bar connection is completed firstly, then the inner side steel formwork and the outer side steel formwork are fixed to the inner side and the outer side of an anti-collision wall respectively, the inner side steel formwork and the outer side steel formwork are connected and fixed to the lower portion and the upper portion through opposite-pull rods, and finally anti-collision wall wet joint concrete is poured. Compared with a traditional construction method, the customized steel formwork is adopted for construction, and the construction appearance quality of cast-in-place concrete is guaranteed; the formwork installation workload is small, operation is convenient, a large number of supports do not need to be erected during high-place operation, the construction efficiency is improved, and safety is guaranteed.
本发明涉及一种用于小箱梁预制防撞墙湿接头无支架的施工方法，采用固定钢模板安装于两端预制的防撞墙上，包括内侧钢模板和外侧钢模板以及上下对拉杆；施工前，防撞墙和小箱梁采用吊装设备吊装至盖梁上，随后桥面横梁施工，完成桥面结构体系转换；施工时，先完成防撞墙湿接头钢筋连接，然后将内侧钢模板与外侧钢模板分别固定在防撞墙内外侧，下部与上部采用对拉杆连接固定内、外侧钢模板，最后浇筑防撞墙湿接头混凝土。本发明与传统施工方法对比，采用定制钢模板施工，保证了现场浇筑混凝土的施工外观质量；模板安装工作量小，操作方便，高处作业无需搭设大量支架，既提高了施工效率，又保证了安全。
