A plurality of extension legs 5 are also installed on the lower end face of the frame base 11, and one end of the extension leg 5 is rotatably connected to the frame base 11. The guardrail frame 1 is provided to ensure that the protective net 2 can be stably installed in the guardrail frame 1. The structure of the guardrail frame 1 ensures that when in use, the vertical shells 12 can be fixedly installed at both ends of the frame base 11, and the protective net 2 can be stably placed through the frame base 11 and the vertical shells 12. At the same time, the positioning seat 3 is fixedly installed on the rear end face of the frame base 11, so that when installation is required during construction, the positioning seat 3 can be fixed on the pre-buried steel bars. At the same time, a positioning frame group 4 that can be flipped open is installed on the front end face of the frame base 11, so that when the protective net 2 needs to be adjusted, it can be flipped up, which is very convenient to use. In addition, by installing a plurality of extension legs 5 on the lower end face of the frame base 11, it is ensured that the extension legs 5 can be flipped and stored in the lower end face of the frame base 11 when not in use, and can be flipped out from the lower end face of the frame base 11 when it is required, thereby increasing the stability of the guardrail when placed on the ground.

[0032] Reference Figure 2 and Figure 4 As shown, the frame 11 includes a seat plate 111 and a transverse back plate 112. The transverse back plate 112 is provided on the rear end of the seat plate 111 and is integrally formed with the seat plate 111. The structural configuration of the frame 11 ensures that the transverse back plate 112 can be fixedly mounted on the rear end of the seat plate 111 when in use. The transverse back plate 112 is higher than the seat plate 111, which facilitates the stable installation of the lower end of the protective net 2 on the upper end of the seat plate 111. When the protective net 2 is not in use, the upper end can also be stored in the frame 11. The vertical shell 12 includes side panels 121 and a longitudinal back plate 122. The longitudinal back plate 122 is provided on the rear end of the side panels 121 and is integrally formed with the side panels 121.

The locking bolt 32 is threadedly connected to the seat sleeve 31, and the pressure plate 33 is mounted on the head of the locking bolt 32. The pressure plate 33 is rotatably connected to the locking bolt 32. The structural arrangement of the positioning seat 3 ensures that when in use, the seat sleeve 31 can be placed on the embedded steel. Then, the locking bolt 32 is rotated to drive the pressure plate 33 to lock the embedded steel, thereby ensuring that the positioning seat 3 can be stably fixed to the embedded steel.

[0035] Reference Figure 3 and Figure 4 As shown, the positioning frame assembly 4 includes a frame plate 41 and a top frame 42. The top frame 42 is mounted on the head of the frame plate 41 and is fixedly connected to the frame plate 41. A support plate 411 is provided on the inner side of the frame plate 41 for placing the top rod 23. The support plate 411 is integrally formed with the frame plate 41. The structural setting of the positioning frame assembly 4 ensures that it can be rotatably mounted on the base plate 111 through the frame plate 41 during use, thereby pressing and fixing the protective net 2 through the frame plate 41. At the same time, after the top frame 42 is fixed to the head of the frame plate 41, the use strength of the frame plate 41 is increased. It can also be connected and fixed to the vertical shell 12 through the top frame 42, thereby achieving stable position and fixation of the protective net 2 through the positioning frame assembly 4. Side ears 421 corresponding to the side plates 121 are provided at both ends of the top frame 42. The side ears 421 are integrally formed with the top frame 42, and the side plates 121 are provided with threaded holes 422 corresponding to the side ears 421. By providing side ears 421 at both ends of the top frame 42, it can be connected with the side panels 121 during installation, and can be conveniently connected with the threaded holes 422 by passing bolts through the side ears 421 to achieve a fixed connection with each other.

[0036] Reference Figure 5As shown, the extension leg 5 includes a flip plate 51 and a movable plate 52. The movable plate 52 is installed in the flip plate 51 and is slidably connected to the flip plate 51. The structural arrangement of the extension leg 5 ensures that when in use, the flip plate 51 is flipped out from the lower end of the seat plate 111, and then the movable plate 52 is pulled out from the flip plate 51. This increases the overall usable length of the extension leg 5, thereby ensuring the stability of the auxiliary guardrail frame 1 when placed on the ground.

[0037] The implementation principle of the construction guardrail for bridge construction in the embodiment of the present application is as follows: when transporting the construction guardrail, the top rod 23 and the rope net 22 can be stored on the base frame 21 to ensure that the protective net 2 can be stably stored between the frame seat 11 and the positioning frame group 4, thereby protecting the protective net 2. This can avoid damage to the rope net 22 during handling or transportation. After transporting to the location where it needs to be installed, the assembly operation can be carried out. First, the positioning frame group 4 is flipped up from the guardrail frame 1, and then the rope net 22 is lifted up through the base frame 21. After the base frame 21 is hung on the support plate 411 of the positioning frame group 4, it can be The positioning frame group 4 is buckled into the guardrail frame 1, and then the positioning frame group 4 is fixed to the guardrail frame 1 by bolts. Finally, the extension foot 5 is flipped out, and the movable plate 52 is pulled out from the flip plate 51. After the assembly is completed, it can be installed by putting the seat cover 31 on the embedded steel on the ground, and then turning the locking bolt 32 to support the pressure plate 33 on the steel to achieve clamping and fixing. This can ensure the stable protection of the construction guardrail. After the protection is completed, the clamping can be released by reversely rotating the locking bolt 32. In this way, the entire construction guardrail can be removed from the embedded steel bars, which is convenient for quick replacement and storage.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
