Lifting construction method of steel structure cooling tower
The invention relates to a lifting construction method of a steel structure cooling tower, a tower body is divided into a scattered splicing construction section, a scattered splicing inlaying construction section and a lifting construction section from bottom to top, the scattered splicing inlaying construction section is of a single-layer steel structure, the lifting construction section is of a multi-layer steel structure, and the scattered splicing construction section is of a single-layer or two-layer steel structure. Splicing of the scattered splicing construction sections is completed on the ground firstly, then an elevator is arranged, and a lifting jig frame is fixed to the scattered splicing construction sections; splicing of the topmost steel structure is completed on the ground, then the topmost steel structure is lifted by a preset height through a lifting machine to be suspended, connection of the secondary top steel structure and the topmost steel structure is completed through suspension splicing on the ground, and a connecting body is lifted to the preset height to be suspended through the lifting machine; and after assembling and hovering of all layers of steel structures of the lifting construction section are completed in an inverted sequence in this way, the lifting construction section and the scattered assembling construction section are connected into a whole through components. The total lifting weight is low, the steel consumption of the lifting jig frame is small, the construction efficiency is high, and the construction safety risk is low.
本发明涉及一种钢结构冷却塔的提升施工方法，将塔身自下而上划分为散拼施工段、散拼嵌补施工段和提升施工段，散拼嵌补施工段为单层钢结构，提升施工段为多层钢结构，散拼施工段为单层或两层钢结构，先在地面完成散拼施工段的拼装，然后布设提升机，并将提升胎架固定在散拼施工段上；接着在地面完成最顶层钢结构的拼装，然后利用提升机将其提升预设高度悬停，在地面通过悬吊拼装完成次顶层钢结构与最顶层钢结构的连接，利用提升机将连接体提升至预设高度悬停；依次类推逆序完成提升施工段的所有层钢结构拼装及悬停后，利用构件将提升施工段与散拼施工段连为一体。本发明提升总重量低，提升胎架用钢量少，施工效率高，施工安全风险性低。
