Background Art

[0002] A cable tower is a tower-shaped structure that supports the main cables in a suspension bridge or a cable-stayed bridge. It plays an important role in bearing and transferring loads in the bridge structure and is a key component to ensure the stability and safety of the bridge.

[0003] The construction of bridge towers of modern cable-stayed bridges and suspension bridges cannot be separated from hydraulic climbing formwork. With the development of current bridge technology, the stress and structure of bridges are no longer the difficulties faced by engineers. Now, people are beginning to pursue a diversified appearance of bridges. In order to better meet people's aesthetic and visual perception, bridge towers will be more innovative and have more changes in geometric shapes. This is also a new test for the climbing formwork construction technology of tower bridges. Faced with the ever-changing linear shapes of bridge towers and the diamond-shaped, inverted "Y"-shaped, and shuttle-shaped bridge tower shapes, traditional hydraulic climbing formworks need to repeatedly disassemble and assemble the climbing formwork bracket, which brings a lot of unnecessary trouble to the construction. Therefore, how the hydraulic climbing formwork construction technology can adapt to the construction of bridge towers with diverse shapes is a difficult problem that hydraulic climbing formwork technology faces and must solve.

[0095] S35: The inner cavity formwork is constructed on-site using a steel formwork, and the chamfers are processed using a fixed-length formwork, which is connected to the outer formwork via tension screws.

[0096] like Figure 5 As shown, the specific steps for the construction of the crossbeam section in S4 are as follows:

[0107] like Figures 7 to 10As shown, a single-tower cable-stayed bridge shuttle-shaped cable tower curved surface and straight surface hydraulic climbing formwork construction device is suitable for any of the above-mentioned single-tower cable-stayed bridge shuttle-shaped cable tower curved surface and straight surface hydraulic climbing formwork construction methods, wherein the tripod described in S21 includes a longitudinal support rod 1; the middle part of the longitudinal support rod 1 is rotatably connected to a transverse support rod 12; the bottom of the transverse support rod 12 and the side wall of the longitudinal support rod 1 are hinged with a connecting plate 13; the side wall of the connecting plate 13 is connected to a screw rod 14 by bolts; a connecting tube 15 is threadedly connected between a pair of the screw rods 14; the middle part of the connecting tube 15 is symmetrically arranged and rotatably connected to a pair of sleeves 16; the middle part of the sleeve 16 is slidably connected to a protective tube 17; the middle part of the protective tube 17 is installed with a connecting assembly; the connecting assembly includes a connecting ring 21; the connecting ring 21 and the connecting plate 13 are threadedly matched; when working, a pair of screws 14 are respectively connected to a pair of connecting plates 13 Connection, since the transverse support rod 12 will be in a non-horizontal state after the tripod is installed for the first time and the climbing formwork system rises along the side wall of the curved surface of the building, it is necessary to rotate the connecting tube 15 to make a pair of screw rods 14 approach or move away from each other, so as to adjust the angle between the transverse support rod 12 and the longitudinal support rod 1, so that the transverse support rod 12 can remain horizontal during construction, and the end of the protective tube 17 is made to fit with the side wall of the connecting plate 13 by sliding the protective tube 17, and then the end of the protective tube 17 is connected to the connecting plate 13 through the connecting assembly, so that the protective tube 17 protects the internal screw rod 14. During construction, the occurrence of objects hitting the middle of the screw rod 14 and causing deformation of the screw rod 14 is reduced, thereby reducing the occurrence of difficulties in rotating and adjusting the connecting tube 15 due to deformation of the screw 14, and reducing the safety hazards caused by the transverse support rod 12 being in a non-horizontal state due to difficulty in adjustment, which causes workers to construct on an inclined plane.

[0108] like Figures 7 to 10 As shown, the connecting assembly includes a ring 2; the ring 2 is rotatably connected to the middle part of the protective tube 17; the connecting ring 21 is a pair and is symmetrically arranged on both sides of the ring 2; the middle part of the sleeve 16 is symmetrically arranged and fixed with a pair of fixing rings 22; the connecting ring 21 and the fixing ring 22 are threadedly matched; when working, the connecting ring 21 can be threadedly connected to the connecting disk 13 so that the protective tube 17 and the connecting disk 13 are kept in contact with each other to protect the screw 14, or when the screw 14 and the connecting tube 15 need to be disassembled and stored, the connecting ring 21 can be threadedly connected to the fixing ring 22 to limit the pair of protective tubes 17 to the middle part of the connecting tube 15, thereby reducing the impact caused by the random sliding of the protective tube 17 during storage, thereby improving the convenience of use of the device.

[0109] like Figures 7 to 10As shown, a plurality of slide grooves 3 are provided in the middle of the sleeve 16; a plurality of reinforcing plates 31 are fixedly connected to the interior of the protective tube 17; the reinforcing plates 31 are slidably connected to the interior of the slide grooves 3; during operation, when the protective tube 17 is hit by an external object, the protective tube 17 may be deformed, thereby affecting the sliding of the protective tube 17. By providing a plurality of reinforcing plates 31, the impact resistance of the protective tube 17 can be improved, the deformation of the protective tube 17 can be reduced, and the influence of the deformation of the protective tube 17 on the use of the device can be reduced.

[0110] During operation, a pair of screw rods 14 are respectively connected to a pair of connecting plates 13. Since the transverse support rod 12 will be in a non-horizontal state after the tripod is installed for the first time and the climbing formwork system rises along the side wall of the curved surface of the building, it is necessary to rotate the connecting tube 15 to make the pair of screw rods 14 approach or move away from each other, thereby adjusting the angle between the transverse support rod 12 and the longitudinal support rod 1, so that the transverse support rod 12 can remain horizontal during construction, and the end of the protective tube 17 is made to fit with the side wall of the connecting plate 13 by sliding the protective tube 17, and then the end of the protective tube 17 is connected to the connecting plate 13 through the connecting assembly, so that the protective tube 17 protects the internal screw rod 14, and the connecting ring 21 can be threadedly connected to the connecting plate 13 so that the protective tube 17 and the connecting plate 13 remain in contact to protect the screw rod 14, or when the screw rod 14 and the connecting tube 15 need to be disassembled and stored, the connecting ring 21 can be threadedly connected to the fixing ring 22 to limit the pair of protective tubes 17 to the middle of the connecting tube 15.
