Catwalk structure suitable for small-spacing main cable
The invention discloses a catwalk structure suitable for a small-spacing main cable. The catwalk structure comprises an operation walkway, a cable rotating saddle, a bearing cable, a catwalk surface layer and a catwalk portal. The operation walkways are horizontally arranged on the two sides of the tower top of the main tower in the longitudinal bridge direction, and the cable rotating saddles are placed on the two sides of the tower top of the main tower in the longitudinal bridge direction. The bearing cables penetrate through the cable rotating saddles to be placed below the main cable, the multiple bearing cables are symmetrically arranged on the two sides of the center line of the bridge respectively, catwalk panels are horizontally erected on the bearing cables on the two sides respectively, the two catwalk surface layers converge at catwalk door frames, and the catwalk door frames are evenly erected above the bearing cables in the longitudinal bridge direction along a single line. The two main cables penetrate through the same portal. According to the catwalk structure, the surface layer width of the catwalk can be met when the transverse width of the main cable is insufficient, compared with a traditional standard catwalk, the catwalk structure saves transverse channels, the use amount is smaller, the mounting and dismounting process is simpler, the problem of construction difficulty is effectively solved, and the construction efficiency is improved.
本发明公开了一种适用于小间距主缆的猫道结构，包括操作走道、转索鞍、承重索、猫道面层和猫道门架；其中，操作走道水平设置在主塔塔顶纵桥向两侧，转索鞍放置在主塔塔顶纵桥向两侧；承重索穿过转索鞍放置于主缆下方，并承重索有多根，分别对称布置于桥梁中心线两侧，两侧承重索上分别水平架设有猫道面板，两个猫道面层在猫道门架处汇合，猫道门架沿纵桥向单线架设于承重索上方均匀布置，两根主缆均穿过同一门架。本发明的猫道结构能够实现主缆横向宽度不足时同时满足猫道面层宽度，相对于传统标准猫道，本发明猫道结构省去了横向通道，用量更少，安装拆卸流程更加简单，有效的解决了施工困难的问题，提高了施工效率。
