Description

technical field [0001] The invention relates to the field of overall lifting operations of special-shaped steel structure systems, in particular to an auxiliary system for precise matching measurement before the overall lifting of complex steel structures is put in place. Background technique [0002] With the continuous increase of long-span structures and super high-rise structures, traditional construction techniques are gradually fading out in the construction of complex structures such as tall, large, new, and special, and some innovative construction techniques have emerged. Among them, the overall hydraulic synchronization of steel structures Lifting technology has become the main installation method for many long-span steel structure roof systems in recent years due to its advantages of simple equipment, efficient ground assembly, and good safety performance. [0003] The hydraulic synchronous lifting technology uses the hydraulic cylinder as the main lifting equipme...

Problems solved by technology

However, the plane projection of some steel structures is irregular and also has the characteristics of three-dimensional irregular structure. At this time, if the hydraulic overall lifting method is used for construction, the distribution of lifting points is bound to be irregular, so that each The lifting force at the lifting point has a large difference. During the lifting process, the spatial vertical coordinates of each area and each lifting point are quite different. Before the structure to be lifted and the pre-installed structure are aligned, the difference should be reduced. Only within a reasonable range can the counterpart connection be carried out. If the conventional adjustment method is adopted, there will be a lot of repeated manual measurement and calculation and analysis work, and when the lifted structure has been lifted to a higher position, the manual measurement error is large, giving Data analysis and the formulation of height difference adjustment schemes at various points have increased the difficulty
