The invention relates to a bridge deck crane combined hoisting construction device for a closure section of a reinforced concrete superposed beam cable-stayed bridge. The device comprises load distribution beams on the two sides, fixing devices and hoisting systems, the load distribution beams are mounted on the fixing devices, the fixing devices are mounted on bridge deck cranes on the two sides,and the hoisting systems are mounted on the load distribution beams; and a longitudinal adjusting device is arranged between each hoisting system and the corresponding load distribution beam, the longitudinal position of the hoisting systems is accurately adjusted through the longitudinal adjusting devices, and it can be guaranteed that the hoisting point position is accurate. The device is suitable for the working condition that the closure section is small in length and direct combined hoisting by the bridge deck cranes on the two sides cannot be conducted, the device is light in structureand safe and reliable in construction process, it can be guaranteed that loads on the two sides of a bridge are basically kept consistent in the closure section hoisting process, the hoisting in-placeprecision can be guaranteed, meanwhile, the problem of cable force adjustment caused by unbalanced loads on the two sides can be reduced, the construction precision is improved, and the constructioncost is saved.

    本发明涉及一种用于钢混叠合梁斜拉桥合龙段的桥面吊机联合吊装施工装置,包括两侧荷载分配梁、固定装置、吊装系统,所述荷载分配梁安装在固定装置上,所述固定装置安装在两侧桥面吊机上,所述吊装系统安装在荷载分配梁上,所述吊装系统与荷载分配梁之间设置纵向调整装置,通过纵向调整装置精确调整吊装系统的纵向位置,能够确保吊点位置准确。本发明适用于因合龙段长度较小而无法直接采用两侧桥面吊机联合吊装的工况,该装置结构轻便,施工过程安全可靠,能确保合龙段吊装过程中桥梁两侧荷载基本保持一致,并能确保吊装就位的精度,同时能减少因两侧荷载不平衡而导致的索力调整问题,提高施工精度,节约施工成本。
