[0002] As an important transportation facility, the maintenance and repair of bridges are of paramount importance. Traditional maintenance and repair methods mostly rely on scaffolding. However, this method has many shortcomings. First, scaffolding is costly and time-consuming to erect, especially when constructing on large bridges or complex terrain, where cost and schedule issues are particularly prominent. Second, scaffolding is greatly affected by environmental factors such as roads, rivers, and power lines at the bottom of the bridge, which limits the operability and flexibility of the construction.
[0003] While existing side-mounted scaffolding systems on the market have solved some of the problems of scaffolding to a certain extent, they still have shortcomings. Many side-mounted scaffolding systems require counterweights to maintain stability, which not only increases construction costs but also occupies a large amount of space on the bridge deck. In addition, some scaffolding systems have limited load-bearing capacity and large deformation. In order to solve the above technical problems, it is necessary to design a side-mounted scaffolding structure for bridge maintenance and repair. Utility Model Content

It has the advantages of not requiring counterweight, occupying little space on the bridge deck, having high load-bearing capacity, and minimal deformation. It not only provides operating space for personnel but also provides stable support for cast-in-place concrete and formwork. It solves the problems of traditional side-mounted scaffolds that require counterweight to maintain stability, which not only increases construction costs but also occupies a large amount of bridge deck space, and the scaffolds have limited load-bearing capacity and large deformation.

[0008] Preferably, the surface of the bridge abutment has a through hole, through which the suspension rod passes, and the diameter of the through hole is larger than the outer diameter of the threaded pipe.
[0009] Preferably, a fixing plate is fixedly connected to the surface of the suspended platform body, and a fastening mechanism is installed on the surface of the fixing plate. The fastening mechanism includes a fixing ring, one side of which is fixedly connected to the fixing plate. A fixing block is fixedly connected to the surface of the fixing plate. A bolt is passed through the top of the fixing block, and the bottom of the bolt passes through the fixing block and is threadedly connected to the fixing block.

[0020] Please see Figures 1-4 A side-mounted suspended platform structure for bridge maintenance and repair includes a bridge abutment 1, a suspended platform body 2 at the bottom of the bridge abutment 1, a suspension rod 3 fixedly connected to the top of the suspended platform body 2, the top of the suspension rod 3 extending through to the top of the bridge abutment 1, a nut 4 threaded onto the surface of the suspension rod 3, a threaded tube 5 threaded onto the top of the suspension rod 3, a conical block 6 fixedly connected to the top of the threaded tube 5, a lifting rope 7 fixedly connected to the top of the conical block 6, and a winch 8 connected to one end of the lifting rope 7. By using the suspension rod 3 and the nut 4, the suspended platform body 2 can be securely suspended from the bridge. On one side, the suspended platform is highly stable, does not sway, and is highly safe. By setting up threaded pipe 5, conical block 6, lifting rope 7 and winch 8, the lifting rope 7 is wound and wound up, thereby lifting the main body of the suspended platform 2, which facilitates the lifting and installation of the suspended platform. Compared with scaffolding, this suspended platform structure is less expensive and is not affected by roads, rivers, or power lines under the bridge. Compared with other side suspended platforms on the market, it does not require counterweight, occupies less space on the bridge deck, has a large load-bearing capacity, and has less deformation. It not only provides operating space for personnel, but also provides stable support for cast-in-place concrete and formwork, with a high safety factor.
[0021] Please see Figure 3 The bottom of the winch 8 is fixedly connected to the bridge abutment 1. A washer 9 is fixedly connected to the surface of the nut 4. The bottom of the washer 9 contacts the bridge abutment 1. By setting the washer 9, the contact area between the bottom of the nut 4 and the bridge abutment 1 is increased, providing stable support for the suspended platform and improving its stability.
[0022] Please see Figure 1 A support plate 10 is fixedly connected to the top of the bridge abutment 1, and a pulley 11 is fixedly connected to the top of the support plate 10. The suspension rope 7 is used in conjunction with the pulley 11. By setting the pulley 11, the suspension rope 7 is supported, which facilitates the stable transmission of the suspension rope 7 and keeps the boom 3 bearing the vertical force of the suspension rope 7, so that the boom 3 can move vertically.
[0023] Please see Figure 3The surface of the bridge abutment 1 is provided with a through hole 12, through which the hanger 3 passes. The diameter of the through hole 12 is larger than the outer diameter of the threaded pipe 5. By setting the through hole 12 and the tapered block 6, it is convenient for the tapered block 6 to pass through the through hole 12 during the upward movement, so that the hanger 3 can pass through the through hole 12, which is convenient for the fixed installation of the hanger 3. By setting the threaded pipe 5, it is convenient to connect with the hanger 3 by thread, and at the same time, it is convenient for them to be disassembled.
[0024] Please see Figure 4 A fixing plate 13 is fixedly connected to the surface of the suspended platform body 2. A fastening mechanism 14 is installed on the surface of the fixing plate 13. The fastening mechanism 14 includes a fixing ring 15. One side of the fixing ring 15 is fixedly connected to the fixing plate 13. A fixing block 16 is fixedly connected to the surface of the fixing plate 13. A bolt 17 is connected through the top of the fixing block 16. The bottom of the bolt 17 passes through the fixing block 16 and is threadedly connected to the fixing block 16. A clamping ring 18 is movably sleeved on the surface of the bolt 17. A horizontal tube 19 is clamped between the fixing ring 15 and the clamping ring 18. By setting the bolt 17, the fixing block 16, the bolt 17, the clamping ring 18 and the horizontal tube 19, the clamping ring 18 can be moved vertically to clamp and fix the horizontal tube 19, making the installation stable and facilitating the disassembly and assembly of the horizontal tube 19.
[0025] Please see Figure 4 The bottom of the clamping ring 18 contacts the horizontal tube 19, and the bottom of the bolt 17 penetrates into the inner cavity of the horizontal tube 19. By setting the bolt 17 and inserting it into the inner cavity of the horizontal tube 19, the horizontal tube 19 is clamped and fixed, which improves the stability of the horizontal tube 19.
[0026] Please see Figure 3 One end of the horizontal tube 19 contacts the fixed plate 13, and the other end of the horizontal tube 19 is connected to the plug rod 20. By setting the horizontal tube 19 and the plug rod 20, personnel can enter the bridge and insert the horizontal tube 19 through the bridge ventilation hole. The other end is quickly connected to the beam ventilation hole using the plug rod 20, which ensures the lateral stability of the suspended platform and increases the safety redundancy of the suspended platform.
[0027] During the suspended platform construction, four through holes 12 are drilled in the bridge flange plate. A winch 8 is used to simultaneously pull the hoisting rope 7. The hoisting rope 7 drives the conical block 6 and the threaded pipe 5 to move upward. The threaded pipe 5 drives the hoisting rod 3 to move upward, so that the hoisting rod 3 passes through the through hole 12. The threaded pipe 5 is disassembled individually, and the gasket 9 is put on the hoisting rod 3. The nut 4 is threaded on the hoisting rod 3. The hoisting rod 9 is used to contact and support the bridge. Then, four sets of nuts 4 are installed on the hoisting rod 3 at the same time to position and support the hoisting rod 3 and the suspended platform body 2. Personnel enter the bridge and insert the horizontal pipe 19 through the bridge ventilation hole. The plug rod 20 is used to quickly connect the horizontal pipe 19 to the beam ventilation hole. The other end of the horizontal pipe 19 is placed between the fixing ring 15 and the clamping ring 18. The rotating bolt 17 drives the clamping ring 18 to move downward, so that the bolt 17 passes through the inner cavity of the horizontal pipe 19. The clamping ring 18 presses against the top of the horizontal pipe 19 to fix the horizontal pipe 19. The horizontal pipe 19 is used to reinforce and support the suspended platform body 2.
[0028] In summary, this side-mounted suspended platform structure for bridge maintenance and repair, through the platform body 2, lifting rod 3, nut 4, threaded pipe 5, conical block 6, lifting rope 7, and winch 8, solves the problems of traditional side-mounted suspended platforms requiring counterweights to maintain stability, which not only increases construction costs but also occupies a large amount of bridge deck space, and the platform has limited load-bearing capacity and large deformation.
