Description

Technical Field

[0001] The present invention relates to the technical field of cable connection, and in particular to a connection device for multi-directional intersection of cables. Background Art

[0002] Cable-stayed structures are spatial structural systems composed of tensile flexible cables and rigid rods. They offer superior load-bearing properties and strong spatial spanning capabilities. With the continuous development and advancement of building materials and construction technology, cable-stayed structures are increasingly being used in public buildings with special requirements for architectural space, such as stadiums and exhibition halls.

[0003] The structural design of cable junctions is a crucial step in the design of long-span spatial cable structures. A reasonable junction is essential for structural safety. The rationality of the cable junction design not only affects the ease of fabrication and smooth installation, but also impacts the integrity and reliability of the structure.

[0004] Traditional cable joints typically utilize prefabricated cast steel nodes, which are complex and expensive to manufacture. When multiple cables intersect, traditional joints often employ a mutual avoidance mechanism, positioning the cables in different planes. This creates a complex joint structure and is difficult to construct. Furthermore, when multiple cables at a joint are not aligned in the same plane, out-of-plane bending moments are generated, further increasing the uncertainty of the stress state at the joint and posing a potential safety risk to the structure.
