Description

Technical Field

[0001] The utility model relates to the technical field of construction of decorative panels between cable-stayed bridge towers, in particular to a lifting and positioning device for a special-shaped steel shell decorative panel of a cable-stayed bridge tower. Background Art

[0002] Spatial special-shaped curved surface structures are mostly assembled by steel structure processing and lifted into place as a whole. At present, with the gradual development of the landscape performance of bridge structure design, concrete pedestals are set at the contact surface between the special-shaped cable tower and the decorative panel. As a result, after the conventional process is completed after the structure is assembled, the decorative panel cannot be lifted into place during the overall lifting process due to conflict with the concrete structure. Safely, reliably and accurately lifting the decorative panel into place has become the key to the construction of cable-stayed bridge projects.

[0003] At present, the more common structural conflict problems during the lifting process of steel shell decorative panels include the following two main construction methods: Method 1 is to hoist the decorative panel structure into place in sections. This method can avoid structural collision during the overall lifting by dividing the structure into blocks and hoisting the blocks into place. This method is suitable for low working heights and requires a good working environment for on-site lifting and hoisting equipment, and the workload of high-altitude assembly and welding operations increases; Method 2 is to hoist the decorative panel outside the tower as a whole to the designed height, and then weld it after longitudinal traction to the designed plane position. This method is suitable for decorative panels with a small area and construction in a windless environment, and there is a diagonal pulling operation against the wind during the longitudinal traction process. The above two construction methods complete the lifting and placement by avoiding the structural conflict parts during the lifting of the decorative panel, but they are relatively suitable for construction at a relatively low height, and have too high requirements for the construction environment, and the high-altitude operation process is complicated, and the construction safety, economy and applicability are poor.

[0004] The above information disclosed in the background technology section is only used to enhance the understanding of the background of the present invention and therefore may contain information that does not constitute the prior art known to ordinary technicians in this field.
