Description

Technical Field

[0001] The present application relates to the technical field of cable-stayed bridges, and in particular to a pre-embedded casing positioning structure for cable-stayed bridges. Background Art

[0002] The embedded sleeves of cable-stayed bridges refer to the sleeves reserved in the piers or the beams above the piers during the construction of cable-stayed bridges in order to fix the cable-stayed cables. Usually, embedded sleeves are set at the nodes of the main beams and bridge towers of the bridge. The cable-stayed cables are inserted into the interior of the bridge structure through these sleeves to ensure a firm connection between the cable-stayed cables and the bridge structure.

[0003] A cable-stayed bridge cable sleeve mentioned in an existing Chinese public patent (authorization announcement number: CN219385978U) can be connected to the outside of the threaded sleeve through two sealing covers, and the sealing cover is fixed by a connecting plate and a fixing screw. The sealing cover is then rotated to move it downward and cover the outside of the sleeve. The sealing cover is fixed by turning two nuts. The sealing cover and the outer convex ring can have a good protective effect and effectively prevent rainwater from penetrating therein. At the same time, when the inclined cable shakes, the sealing cover can shake with it, ensuring that the equipment can be used continuously. At the same time, it is very convenient to disassemble during maintenance.

[0004] During the construction process of the existing embedded casing, the staff needs to adjust the angle of the embedded casing to make it reach the design required angle. Most of the existing tools need to use slings, ropes and other tools to adjust the position of the casing. However, using slings, ropes and other tools to adjust the embedded casing is time-consuming and labor-intensive, the construction efficiency is low, and it is inconvenient for the staff to use.

[0035] When positioning the embedded sleeve 6, first fix the prefabricated part 3 inside the empty groove 2, and threadably connect the embedded sleeve 6 with the rotating seat 5 so that the embedded sleeve 6 is fixedly connected to the rotating seat 5, and then adjust the angle of the embedded sleeve 6 by rotating the embedded sleeve 6, so as to realize the positioning of the embedded sleeve 6. After the angle positioning of the embedded sleeve 6 is completed, pour concrete inside the empty groove 2 to fix the embedded sleeve 6. When adjusting the angle of the embedded sleeve 6, the adjustment mechanism is used to facilitate the adjustment of the angle of the embedded sleeve 6, thereby improving the construction efficiency and facilitating the use of the staff. The embedded sleeve 6 after the angle is adjusted can be supported by the supporting mechanism, thereby further increasing the stability of the embedded sleeve 6.

[0040] When adjusting the angle of the embedded sleeve 6, firstly, the handle 23 is turned to drive the threaded rod 8 to rotate. After the threaded rod 8 rotates, the threaded block 9 is moved, so that the threaded block 9 moves inside the long hole 14, and the threaded block 9 is fixedly connected with the rotating seat 2 10, so that the rotating seat 2 10 moves.

After the angle positioning of the embedded sleeve 6 is completed, pour concrete inside the empty groove 2 to fix the embedded sleeve 6. When adjusting the angle of the embedded sleeve 6, first move the rotating seat 2 10 through the driving member, and the rotating seat 2 10 drives the connecting rod 11 to move after the movement, and the other end of the connecting rod 11 is rotatably connected with the rotating seat 3 12, so that the connecting seat 3 moves accordingly, and then the connecting seat 3 is fixedly connected with the embedded sleeve 6, thereby driving the embedded sleeve 6 to move, so that the angle of the embedded sleeve 6 changes, and the angle of the embedded sleeve 6 can be adjusted by rotating the handle 23.
