Hydraulic lifting and hoisting method for steel-concrete combined section
The invention discloses a method for hydraulic lifting and hoisting of a steel-concrete combined section, which comprises the following steps: S1, preparation before hoisting: assembling the steel-concrete combined section on the ground, and mounting a lifting lug and a lower lifting appliance at the top of the steel-concrete combined section; meanwhile, a bailey truss and an ultra-large component hydraulic lifter are installed on the concrete beam, and a special lifting appliance is connected with a lifting point of the lifter; s2, trying to lift: lifting the reinforced concrete section to be 100mm away from the ground, leveling the reinforced concrete section, and standing for 12 hours; s3, formal lifting is conducted, specifically, after the steel-concrete combined section is lifted to the position close to the design position, lifting is suspended, and all lifting points enable the lifted steel-concrete combined section to be accurately in place through the fine adjustment and inching functions of a computer synchronous control system; and S4, graded unloading is conducted, specifically, all loads of the steel-concrete combined section are transferred to a concrete beam, and then hydraulic lifting equipment and temporary lifting measures are dismantled. The construction quality can be effectively guaranteed, the construction efficiency is improved, the construction period is shortened, the construction risk is reduced, and the construction cost is controlled.
本发明公开了一种钢混结合段液压提升吊装的方法，所述方法包括S1：吊装前准备：钢混结合段在地面拼装好，并在顶部安装吊耳和下吊具；同时，在混凝土梁上安装贝雷桁架与超大型构件液压提升器，并用专用吊具与提升器吊点连接；S2：试提升：将钢混段提升离地100mm，对钢混段进行调平并静止12小时；S3：正式提升：将钢混结合段提升至设计位置附近后，暂停提升，各提升吊点通过计算机同步控制系统的“微调、点动”功能，使被提升钢混段精确就位；S4：分级卸载：将钢混结合段全部荷载转移到混凝土梁上，然后拆除液压提升设备和提升临时措施。本发明能有效保证施工质量、提高施工效率、缩短施工周期、降低施工风险以及控制施工成本等。
