It should be explained that the examples and features in the examples of the present application can be combined with each other without conflict.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as Figures 1-6 As shown, this utility model provides a hollow thin-walled pier internal cavity working platform support, including a thin-walled body 1. A plurality of evenly distributed first sleeves 7 are fixedly installed on one side of the thin-walled body 1. A plurality of evenly distributed second sleeves 9 are fixedly installed on the end of the thin-walled body 1 away from the first sleeves 7. Both the first sleeves 7 and the second sleeves 9 have internal threads 14. The first sleeves 7 and the second sleeves 9 are respectively provided with first reinforcing bars 8 and second reinforcing bars 10. The outer walls of the first reinforcing bars 8 and the second reinforcing bars 10 are provided with external threads 15. The external threads 15 are threadedly connected to the internal threads 14. A U-shaped seat 11 is provided between the first reinforcing bars 8 and the second reinforcing bars 10. Two bolts 17 are fixedly installed on the inner wall of the U-shaped seat 11.

Nuts 18 are threadedly connected to the outer walls of the bolts 17. A steel plate 2 is provided on the top of the U-shaped seat 11.

[0025] The overall effect of Embodiment 1 is as follows: During construction, workers pre-install a first sleeve 7 and a second sleeve 9 on both sides inside the thin-walled body 1. Then, the external threads 15 of the first reinforcing bar 8 and the second reinforcing bar 10 are threadedly connected to the internal threads 14 of the first sleeve 7 and the second sleeve 9, respectively. At this time, workers place the U-shaped seat 11 in the middle position between the first sleeve 7 and the second sleeve 9, and insert the first reinforcing bar 8 and the second reinforcing bar 10 into the U-shaped seat 11 so that they fit against the inner wall of the U-shaped seat 11. Then, workers insert the pressure plate 12 into the U-shaped seat. Inside 11, bolt 17 passes through through hole 16. Finally, the worker connects nut 18 to bolt 17 with threads and rotates nut 18 downwards. Nut 18 pushes pressure plate 12 down until pressure plate 12 contacts the top of first reinforcing bar 8 and second reinforcing bar 10. Pressure plate 12 applies pressure to first reinforcing bar 8 and second reinforcing bar 10, increasing friction and fixing U-shaped seat 11. Finally, worker places steel plate 2 on U-shaped seat 11. In this way, worker can work on top of steel plate 2, improving installation efficiency, allowing for reuse, and reducing costs.

[0026] Example 2, as Figures 1-6As shown, the top of the steel plate 2 is provided with a protective groove 5, and the inner wall of the protective groove 5 is provided with a storage groove 19. The storage groove 19 is fixedly installed on both sides. An adjusting seat 21 is fixedly installed between the two fixed rods 20. The bottom of the adjusting seat 21 is provided with an adjusting groove 22. A threaded rod 23 is rotatably installed inside the adjusting groove 22. One end of the threaded rod 23 passes through the adjusting seat 21 and is fixedly installed with a handle 24. The outer wall of the threaded rod 23 is threadedly connected to two sliders 25. A locking block 26 is fixedly installed on the opposite side of the two sliders 25.

[0027] Furthermore, slots 13 are provided on both sides of the U-shaped base 11.

[0028] Furthermore, a rotating shaft 27 is rotatably installed on the inner wall of the protective groove 5, and a protective plate 6 is fixedly installed on the outer wall of the rotating shaft 27. An L-shaped groove 28 is opened on the outer wall of the protective plate 6. The staff can pull the protective plate 6 by inserting their fingers into the L-shaped groove 28.

[0029] Furthermore, a limiting groove 29 is provided on the outer wall of the protective plate 6, a spring 30 is fixedly installed on the inner wall of the limiting groove 29, a connecting block 31 is fixedly installed on one end of the spring 30, a through opening 33 is provided through the top surface of the limiting groove 29, a pull plate 34 is fixedly installed on the top of the connecting block 31, a groove 35 is provided on the top of the pull plate 34, a baffle 36 is fixedly installed on the outer wall of the pull plate 34, one end of the baffle 36 is slidably inserted into the inner wall of the through opening 33, and a connecting groove 32 is provided on the inner wall of the protective groove 5.

[0030] Furthermore, a groove 3 is provided on the top of the steel plate 2, and a tie rod 4 is fixedly installed on the inner wall of the groove 3 to facilitate the movement of the steel plate 2 by the staff.

[0031] Furthermore, the threaded rod 23 is provided with two sections of threads with opposite textures. The threaded rod 23 is connected to two sliders 25 respectively through the two sections of threads with opposite textures. When the threaded rod 23 rotates, the two sliders 25 move closer to each other or further away from each other.

[0032] The effect achieved by the entire embodiment 2 is that when the steel plate 2 is placed on top of the U-shaped seat 11, the operator rotates the handle 24, the threaded rod 23 rotates, and then drives the two sliders 25 to move closer to each other until the two locking blocks 26 enter the two locking slots 13 respectively. At this time, the steel plate 2 can be fixed to prevent the steel plate 2 from shaking and affecting the normal work of the operator.

[0033] Working principle: During assembly, workers pre-install first sleeves 7 and second sleeves 9 on both sides inside the thin-walled body 1. Then, the external threads 15 of the first reinforcing bar 8 and the second reinforcing bar 10 are threadedly connected to the internal threads 14 of the first sleeves 7 and the second sleeves 9, respectively. At this time, workers place the U-shaped seat 11 in the middle position between the first sleeves 7 and the second sleeves 9, and insert the first reinforcing bar 8 and the second reinforcing bar 10 into the U-shaped seat 11 so that they fit against the inner wall of the U-shaped seat 11. Then, workers insert the pressure plate 12 into the U-shaped seat 11. Bolt 17 passes through through hole 16. Finally, the worker connects nut 18 to bolt 17 via thread and rotates nut 18 downwards. Nut 18 pushes pressure plate 12 down until pressure plate 12 contacts the tops of the first reinforcing bar 8 and the second reinforcing bar 10. Pressure plate 12 applies pressure to the first reinforcing bar 8 and the second reinforcing bar 10, increasing friction and fixing the U-shaped seat 11. Finally, the worker places steel plate 2 on the U-shaped seat 11, allowing the worker to work on top of steel plate 2, improving installation efficiency, allowing for reuse, and reducing costs. When steel plate 2 is placed on top of U-shaped seat 11, the worker rotates handle 24, causing threaded rod 23 to rotate, which in turn drives two sliders 25 closer together until two locking blocks 26 enter the two locking slots 13 respectively. At this point, steel plate 2 is fixed, preventing it from shaking and affecting the worker's normal work. Finally, the staff pulls the pull plate 34, which moves the connecting block 31 and compresses the spring 30. The staff then rotates the protective plate 6, which fully enters the protective groove 5. Finally, the staff releases the pull plate 34, and the elastic force of the spring 30 pushes the connecting block 31 into the connecting groove 32. At this point, the protective plate 6 can protect the adjusting seat 21 and prevent the staff from stepping into the hole.
