Annular tower supporting device of cable-stayed bridge
The cable-stayed bridge annular tower supporting device comprises an annular tower, a positioning beam penetrates through the interior of the annular tower, two rows of stand columns are arranged in the annular tower, the upper ends of the stand columns are connected with the inner side wall of the annular tower, the lower ends of the stand columns are connected with the positioning beam, and every two adjacent stand columns are connected through a connecting piece; a supporting rod and a pull rod are arranged on the side wall of each row of stand columns from top to bottom, the two ends of each supporting rod and the two ends of each pull rod are connected with the side walls of the adjacent annular towers respectively, and a first fork supporting structure is arranged between every two transversely adjacent supporting rods in the two rows of stand columns. Second fork supporting structures are arranged between the supporting rods and the pull rods which are longitudinally adjacent to each other on each row of stand columns. The rigidity of the cable bent tower sections in the subsequent construction process is increased, the situation that the pull rods and the supporting rods deform due to the action of vertical force and lose original functions is avoided, meanwhile, the construction period is shortened, and the construction cost is reduced.
本发明公开了一种斜拉桥环形塔支撑装置，包括环形塔，所述环形塔内部贯穿定位梁，所述环形塔内部设置有立柱，所述立柱分布有两排，所述立柱上端与环形塔的内侧壁连接，下端与定位梁连接，每相邻的两个立柱通过连接件连接；所述每一排立柱的侧壁由上至下均设置有支撑杆和拉杆，支撑杆和拉杆的两端分别与靠近的环形塔侧壁连接，所述两排立柱中，横向相邻的两个支撑杆之间设置有第一叉撑结构，每一排立柱上纵向相邻的支撑杆和拉杆之间均设置有第二叉撑结构。增大了索塔节段在后续施工过程中的刚度，又避免了拉杆、撑杆因为竖向力作用产生变形而丧失原有功能，同时，节省了施工工期，降低了施工成本。
