Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a hoisting device for integrally hoisting steel bar components of polygonal variable-section inclined tower columns. Background Art

[0002] With the continuous development of bridge construction technology, the requirements for safety, efficiency and quality in the construction process are becoming higher and higher. In the construction process of super-high bridge towers, the traditional tower column steel bar loose binding construction process has problems such as low construction efficiency, high operation risk, and difficult to control construction quality. Therefore, the tower column steel bar componentized overall hoisting construction is more and more widely used. Compared with traditional loose binding construction, tower column steel bar componentized construction can transform high-altitude steel bar binding operations to ground operations. The overall hoisting and rapid docking technology is used to greatly reduce the risk of high-altitude operations, improve construction efficiency, ensure construction quality, and realize the rapid construction of super-high bridge towers.

[0003] However, for the towers of extra-large bridges, their cross-sectional form is often a variable cross-sectional form, that is, the towers shrink from bottom to top. Therefore, the shapes and sizes of various components are often different, and their center of gravity positions are also different. At the same time, there are errors in the production process of steel components, and there are often deviations between the theoretical center of gravity and the actual center of gravity of the components. During the lifting process, the center of gravity of the steel component and the lifting center of gravity are often not on the same vertical line, causing the steel component to tilt during lifting, which increases the difficulty of installing the steel component on the tower and increases the safety risk of lifting. At the same time, since the steel bar shrinks with the tower, the cross-sectional size of each component segment is different, and the position of the lifting point of the connecting steel bar is also different. If the traditional lifting fixture is used, it is necessary to make multiple lifting fixtures to adapt to the changes in the lifting points of the steel component. This method is cumbersome to construct and has a high cost.
