Catwalk cable rotating saddle structure supported at grille, catwalk cable rotating saddle system and catwalk cable rotating saddle method
The invention belongs to the technical field of suspension bridge superstructure construction, and particularly relates to a catwalk cable rotating saddle structure supported at a grating, a catwalk cable rotating saddle system and a catwalk cable rotating saddle method. The catwalk rotating cable saddle structure supported at the grating at least comprises the grating, and grating brackets are symmetrically connected to the two sides of the lower portion of the grating respectively. The catwalk rotating cable saddle structure further comprises a catwalk rotating cable saddle at the grating. The lower portion of the catwalk cable rotating saddle at the position of the grid is connected to the grid bracket, and the upper portion of the catwalk cable rotating saddle at the position of the grid is connected to the grid. The catwalk cable saddle system is composed of a cable bent tower, a catwalk cable saddle structure supported at the grating and two groups of catwalk cable saddles arranged at the top of the cable bent tower. Through the force cooperation of the two groups of catwalk cable rotating saddles arranged at the top of the cable bent tower and the catwalk cable rotating saddle structure supported at the grating, the arrangement of the continuous catwalk at the top of the tower under the large pre-bias of the main cable saddle is ensured, so that the line shape of the catwalk meets the requirements of construction operation, the smoothness of the line shape of a catwalk bearing cable at the top of the tower is ensured, and the service life of the catwalk is prolonged. And upper structure construction is facilitated.
本发明属于悬索桥上部结构施工技术领域，具体涉及一种支撑于格栅处的猫道转索鞍结构、系统及方法。本发明中的支撑于格栅处的猫道转索鞍结构至少包括格栅，格栅下部两侧分别对称的连接有一个格栅牛腿：还包括格栅处猫道转索鞍；格栅处猫道转索鞍的下部连接在格栅牛腿上，格栅处猫道转索鞍的上部连接在格栅上。由索塔、支撑于格栅处的猫道转索鞍结构及设置在索塔塔顶处的两组猫道转索鞍构成猫道转索鞍系统。本发明通过设置在索塔塔顶处的两组猫道转索鞍及支撑于格栅处的猫道转索鞍结构的通力配合，保证了主索鞍大预偏量下连续式猫道在塔顶的布置，使得猫道线形满足了施工作业的要求，保证了猫道承重索线形在塔顶处的平顺性，有利于上部结构施工。
