[0002] In modern bridge engineering, the cable tower as the key structure supporting the cable, its design and construction quality are directly related to the safety and stability of the whole bridge. With the continuous increase of bridge span and the improvement of bridge bearing capacity requirements, higher requirements are put forward for the design of cable tower and its related components. Under this background, steel anchor beam as an important part connecting main cable and cable tower, its performance and reliability are particularly critical. However, the traditional installation method of steel anchor beam often faces the problems of complex construction, low efficiency and so on.

[0003] In order to solve these problems, a special structure for connecting steel anchor beam and cable tower body-steel heddle emerges as the times require. Steel heddle, through its unique design, not only simplifies the installation process of steel anchor beam, but also improves the stability and bearing capacity of the whole cable tower system. It is usually fixed at a specific position of the cable tower to provide a solid and reliable connection point for the steel anchor beam, ensuring that the cable can effectively transfer the load to the cable tower and finally disperse to the foundation.
