[0001] The utility model relates to the technical field of building tools, in particular to an aerial positioning device for a special-shaped curved surface structure template. Background Art

[0002] At present, the chimneys of some power plants are designed as rectangular special-shaped structures. For example, the chimney of a certain project is designed to be 243m high, with a plane size of 23m×17.8m, a pair of straight sides, a pair of curved surfaces, and an irregular special-shaped structure of the curved surface. The spatial volume of this type of structure is huge, and a hydraulic mold lifting device is used as a construction platform. The steel formwork is constructed by turning the mold. As the chimney structure is constructed section by section, the structural positioning becomes more and more difficult, especially for the high-altitude positioning of the curved surface structure. The traditional aerial positioning of the curved surface structure uses a ruler to pull the distance to position the curved surface template. This method not only has low control accuracy, but also has great difficulty in operation, which is not conducive to the control of construction progress and the quality of the curved surface structure.
