The invention relates to a steel truss girder falling construction tool and a girder falling construction method.The steel truss girder falling construction tool comprises hoisting equipment, a sliding assembly, a girder falling assembly and two lifting assemblies acting on the two ends of a steel truss girder, and the technical scheme that the steel truss girder is assembled at a low position, and after the steel truss girder is overall lifted, the steel truss girder is transversely moved to complete girder falling in place is achieved. And compared with cast-in-place, the manufacturing and mounting time of the prefabricated steel truss girder is shorter, the low-position splicing line shape is convenient to adjust, and the mounting precision is higher. And meanwhile, a special lifting scheme is adopted, the two ends of the cross beam are stably supported by the upper supports, the stability difficulty of hoisting and lifting is overcome, lifting and falling of the steel truss girder on the slideway beam can be achieved only through vertical movement, the action step sequence is simple, and the falling position of the steel truss girder can be effectively controlled. The construction method at least has the technical effects that the lifting is stable, the construction difficulty is low, the construction period is effectively shortened, the construction cost is controlled, and the use of existing traffic facilities, water areas and artificial facilities is not influenced.
本申请涉及一种钢桁梁落梁施工工装以及落梁施工方法，钢桁梁落梁施工工装包括吊装设备、滑移组件、落梁组件和作用于钢桁梁的两端的两个提升组件，以实现低位拼装钢桁梁并将钢桁梁整体提升后横移完成落梁到位的技术方案。与现场浇筑相比，预制钢桁梁的制造和安装时间更短，低位拼装线形调整方便、安装精度较高。同时本申请采用了特殊的提升方案，横梁的两端均由上支架稳定支撑，克服了起重提升的稳定性难点，使得钢桁梁的提升和落在滑道梁均可仅由竖直移动实现，动作步序简单，且能有效控制钢桁梁的落位位置。本申请至少具有稳定提升、施工难度低、有效缩短施工工期、控制施工成本且不影响既有的交通设施、水域以及人造设施的使用的技术效果。
