Wind-resistant anti-collision structure suitable for high-low four-main-cable catwalk and installation method
The invention relates to the technical field of catwalk structures for suspension bridge construction, in particular to a wind-resistant anti-collision structure suitable for a high-low four-main-cable catwalk and a mounting method. Comprising an inner catwalk and an outer catwalk which are located on the same side of a main beam. The inner side catwalk comprises an inner side bearing cable, a support and inner side bearing cable, an inner side catwalk surface layer and an inner side catwalk portal stand column; the outer catwalk comprises an outer bearing cable, an outer catwalk surface layer and an outer catwalk portal stand column; the inner side bearing cable is located above the outer side bearing cable; a gap is reserved between the inner side catwalk and the outer side catwalk in the transverse bridge direction, and a buffer structure for avoiding rigid collision between the inner side catwalk and the outer side catwalk is arranged in the gap; and the inner catwalk is connected to the outer catwalk through a buffer structure in a manner of moving in the vertical direction and the transverse direction of the bridge. The anti-collision structure is simple, rigid collision between the inner catwalk and the outer catwalk on the same side can be effectively avoided when the anti-collision structure is applied to the high-low four-main-cable catwalk, the buffering and energy absorbing effects are extremely good, and great popularization value is achieved.
本发明涉及悬索桥施工的猫道结构技术领域，具体地指一种适用于高低四主缆猫道的抗风防碰撞结构以及安装方法。包括位于主梁同侧的内侧猫道和外侧猫道；内侧猫道包括内侧承重索以及支撑与内侧承重索、内侧猫道面层和内侧猫道门架立柱；外侧猫道包括外侧承重索、外侧猫道面层和外侧猫道门架立柱；内侧承重索处于外侧承重索的上方；内侧猫道与外侧猫道在横桥向方向上留有间隙，间隙内设置有避免内侧猫道和外侧猫道相互之间刚性碰撞的缓冲结构；内侧猫道通过缓冲结构可竖向和横桥向移动的连接于外侧猫道。本申请的防碰撞结构简单，应用在高低四主缆猫道上能够有效避免同侧内外猫道之间的刚性碰撞，缓冲吸能的效果极好，具有极大的推广价值。
