Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, and in particular to a cable-stayed bridge with a Möbius ring-shaped spatial arch tower. Background Technology

[0002] Currently, the tower designs of cable-stayed bridges mostly follow classical mechanical paradigms, primarily using planar geometric configurations such as H-shapes and A-shapes. While such structures can ensure efficient load transfer, the uniformity of spatial design leads to a convergence of visual expressions, making it difficult to meet the demand for unique artistic symbols for urban landmark bridges. In the field of urban landscape bridges, the contradiction between the public's aesthetic expectations of bridges as "three-dimensional public works of art" and conservative structural selection is becoming increasingly prominent.

[0003] Some designs adopt exaggerated and unconventional shapes to break visual conventions, but due to the disconnect between aesthetic expression and mechanical logic, problems such as engineering waste or safety hazards have arisen. Form innovation that deviates from structural rationality has weakened the core value of bridges.

The second indirect force transmission cable is disposed between the structural ring and the second arch tower. One end of the second indirect force transmission cable is connected to the outer side of the structural ring, and the other end is anchored to the upper half of the second arch tower.

[0009] Preferably, the bottoms of the first arch and the second arch overlap, together forming a continuous Möbius strip shape.

[0010] Preferably, the direct force transmission cable is disposed between the first arch tower and the second arch tower, the direct force transmission cable passes through the hollow area of ​​the structural ring, one end of the direct force transmission cable is connected to the first arch tower, and the other end is connected to the second arch tower.
