The invention discloses a combined bridge structure for an expressway. The combined bridge structure comprises a bridge main body and an inhaul cable above the bridge main body, a tensioning piece is installed in the middle of the inhaul cable and comprises a piece main body, a side cover and a wheel cover, the side cover and the wheel cover are located on the two sides of the piece main body, a worm and a worm gear are arranged between the side cover and the piece main body, a cable wheel is arranged between the piece main body and the wheel cover, a middle cavity, two side cavities and a main cavity are formed in the side cover, the inner space of the middle cavity, the inner space of the side cavities and the inner space of the main cavity are communicated, the two side cavities are formed in the two ends of the middle cavity, a cover penetrating hole penetrating through the side cover is formed in the circle center of the main cavity, and a plurality of cover through holes penetrating through the side cover are formed in the side cover. A middle cavity, two side cavities and a main cavity are formed in the piece main body, the inner space of the middle cavity, the inner space of the side cavities and the inner space of the main cavity are communicated, and the number of the side cavities is two. The combined bridge structure for the expressway can eliminate partial vibration of the inhaul cables and is suitable for being widely popularized and used.
本发明公开了一种用于高速公路的组合式桥梁结构，包括桥主体和其上方的拉索，所述拉索中部安装有张紧件，所述张紧件包括件主体和位于其两侧的侧盖和轮盖，所述侧盖和件主体之间设有蜗杆和蜗轮，所述件主体和轮盖之间设有索轮，所述侧盖内部开有中腔、侧腔和主腔，所述中腔、侧腔和主腔的内部空间连通，所述侧腔开有两道，两道所述侧腔位于中腔的两端，所述主腔的圆心开有穿过侧盖的盖穿孔，所述侧盖内部开有若干将其贯穿的盖通孔，所述件主体内部开有中腔、侧腔和主腔，所述中腔、侧腔和主腔的内部空间连通，所述侧腔开有两道。该用于高速公路的组合式桥梁结构，可消除拉索的部分震动，适合普遍推广使用。
