Dismantling method and hoisting device for cast-in-place box girder bailey beam support
The invention further provides a dismantling method and a hoisting device of the cast-in-place box beam bailey beam support, the hoisting device comprises a plurality of hanging brackets, and each hanging bracket is provided with a hook capable of ascending and descending; the hanging brackets are placed on the upper end faces of the box girder bailey pieces respectively, a plurality of reserved holes are formed in the upper end faces of the box girder bailey pieces in the transverse direction, one hanging bracket is placed in each reserved hole, and the hanging brackets can penetrate through the reserved holes in the bailey pieces in the vertical direction and stretch into a bailey beam support at the bottom of a box girder. Therefore, the bailey beam supports are hooked through the hooks on the steel wire ropes respectively and are bound firmly. According to the dismantling method of the cast-in-place box girder Bailey beam support and the lifting device, the Bailey beam support can be effectively dismantled, the number of machine teams and the number of workers can be reduced, the production efficiency is improved, the machine teams of operation cranes are reduced by 90%, the number of the workers is reduced by 50%, the dismantling efficiency is greatly improved, the working environment of the workers is improved, and the working safety of the workers is greatly guaranteed.
本发明还提供一种现浇箱梁贝雷梁支架的拆除方法及起吊装置，所述起吊装置包括多个吊架，各个吊架上分别设有能够升降的挂钩；各个吊架分别安放于箱梁贝雷片的上端面上，并且箱梁贝雷片的上端面上沿横向设有多个预留孔，每个预留孔安放有一个吊架，各个吊架能够沿竖直方向穿过贝雷片上的预留孔，并伸入箱梁底部的贝雷梁支架上，从而通过钢丝绳上的挂钩分别勾住贝雷梁支架，并绑扎牢固；本发明提供的的现浇箱梁贝雷梁支架的拆除方法及起吊装置，能够有效拆除贝雷支架，可减少机械台班及工人使用数量，提高生产效率，操作吊车台班减少90%，工人减少50%，大大提高拆除效率，改善工人作业环境，使得工人作业安全得到极大保障。
