Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering construction, in particular to an assembled multi-posture cable anchoring device for an inclined-stayed buckle-hanging system. Background Art

[0002] Steel box rib arch bridge is a common arch bridge structure. The main arch ring of the steel box rib arch bridge is assembled from steel box arch segments made of high-strength steel. Large-span steel box arch bridges generally adopt the construction method of cable hoisting and inclined stay buckle hanging. This method requires the erection of a buckle hanging system and a cable hoisting system. After the arch rib segments are prefabricated in the factory, they are transported to the construction site. The cable hoist hoists the arch ribs to the corresponding positions for installation. At the same time, the buckle cables are tensioned to the buckle towers and connected to the ground anchors to fix the arch ribs. The cable and buckle systems work together to install the arch rib segments one by one until they are closed.

[0003] When installing the arch rib segments, adjacent arch rib segments are assembled by welding and fixed with buckle cables. Due to the influence of the deadweight of the new segment, the buckle tower and the installed arch rib segment change greatly. At this time, the buckle cable force needs to be adjusted to ensure the installation line of the arch rib. During the installation of the arch segment and the adjustment of the buckle cable, the anchor end of the buckle cable will be forced to rotate due to the change of the buckle tower and the arch rib line. The existing anchoring device is generally limited to the rotation of the buckle cable in one plane, and it is difficult to achieve the multi-angle change of the buckle cable, resulting in friction damage between the buckle cable and the anchoring device, causing safety accidents. Therefore, in order to avoid the buckle cable from bearing a large lateral force during the installation of the arch rib and adapt to the multi-angle change of the buckle cable during the arch rib construction, a targeted buckle cable anchoring method is developed.
