The invention discloses a blast furnace shaft frame combination hoisting method which is characterized in that a furnace body frame of the blast furnace shaft frame combination hoisting method is integrally assembled on the ground, and four stand columns and platform beams of the integral frame are integrally combined and spliced on the ground through mutual cooperation of ground manpower and a gantry crane, so that the construction process is greatly simplified; the combined hoisting method for the furnace body frame of the blast furnace greatly shortens the construction period, facilitates further quality detection and accurate positioning of butt joint of the upper frame and the lower frame, can greatly improve the quality and precision in the construction process, is high in installation efficiency, greatly saves time and manpower, is good in safety, and is suitable for large-scale popularization and application. Due to the fact that the whole structure completes most butt joint and welding work on the ground, the risk of aerial work is reduced, the quality is reliable, and due to the fact that most butt joint and welding work is completed on the ground, the butt joint position and the welding seam quality are easy to control.
本发明公开了高炉炉身框架组合吊装方法,该高炉炉身框架组合吊装方法的炉体框架整体在地面组装,通过地面人工、龙门吊的相互配合,将整体框架的四根立柱和平台梁进行地面整体组合拼装,极大的简化了施工工序,大幅度的缩短了施工工期,同时也方便进一步的质量检测以及上部框架和下部框架对接的精准定位,可以大幅度提高施工过程中的质量以及精度,该高炉炉身框架组合吊装方法的安装效率高,大大节省了时间和人力,安全性好,因为整体结构在地面上完成大部分的对接和焊接工作,减少了空中作业的风险,质量可靠,因为整体结构在地面上完成大部分的对接和焊接工作,对接位置和焊缝质量易于控制。
