Anti-overturning mounting structure and method for prefabricated box girder of cantilever bent cap
The invention discloses an anti-overturning mounting structure and method for a prefabricated box girder of a cantilever cover beam, and the structure comprises a to-be-erected box girder, the two ends of the to-be-erected box girder are used for being erected on support cushion stones at the to-be-erected positions of two cantilever cover beams respectively; the annular hanging belt is arranged on the suspended part of the cantilever cover beam in a sleeving mode and distributed on the side, provided with the short flange plate, of the to-be-erected box beam; a lifting hook at one end of the first chain hoist is hung on a wet joint reinforcing steel bar, on one side of the short flange plate, of the to-be-erected box girder, and a lifting hook at the other end of the first chain hoist is used for hooking and tightening the annular lifting belt. According to the anti-overturning mounting structure and method, the overturning moment generated by the unbalanced side of the short flange plate and the long flange plate is counteracted through the annular hanging belt and the cantilever bent cap, the anti-overturning mounting structure and method are suitable for construction of the prefabricated box girder where a fulcrum cannot be arranged, and the application range is wider.
本申请公开一种悬臂盖梁的预制箱梁的抗倾覆安装结构及方法，抗倾覆安装结构包括：待架设箱梁，其两端用于分别架设在两个悬臂盖梁的待架设位置的支座垫石上；环形吊带，套设在悬臂盖梁的悬出部分，且分布在待架设箱梁具有短翼缘板一侧；第一手动葫芦，一端的吊钩挂接在待架设箱梁在短翼缘板一侧的湿接缝钢筋上，另一端的吊钩用于钩住所述环形吊带并收紧。本申请抗倾覆安装结构及方法利用环形吊带与悬臂盖梁来抵消短翼缘板和长翼缘板不平衡侧产生的倾覆力矩，适用于无法设置支点的预制箱梁的施工，适用范围更广。
