[0021] As Figures 1-2 Shown, the utility model mentions a kind of bridge guardrail edge protection fixing device, including sleeve 3 for being installed on edge protection steel pipe, sleeve 3 outer wall and oppositely arranged with a first nut 2 and a pair of horn arm 4, first nut 2 is connected with the first screw 1 that is threadedly matched with it and is used to stop edge protection steel pipe, can fasten and stop edge protection steel pipe, ensure the stability of sleeve;Single horn arm 4 is provided with second screw 5, and the end of one of second screw 5 is provided with the second nut 6 that is threadedly matched with another second screw 5, for adjusting and fixing the position of guardrail;Sleeve 3 is provided with adjusting assembly between a pair of horn arm 4, and angle steel 7 is provided at the end of adjusting assembly away from sleeve 3, and the opening of angle steel 7 is towards second nut 6 and cooperates with it to stop embedded steel bar.

[0022] Installation Process: First, pull out the two second screws 5 on the pair of yoke arms 4, then position the pair of yoke arms 4 towards the pre-embedded reinforcing bars in the beam (not shown), and bring the angle steel 7 close to the pre-embedded reinforcing bars. Next, pull the two second screws 5 on the pair of yoke arms 4 inward, and screw one second screw 5 into the nut 6 on the other second screw 5. Then, adjust the angle steel 7 to engage with the second nut 6 or any of the second screws 5 using the adjusting assembly, securing it against the pre-embedded reinforcing bars in the beam to ensure a stable and reliable connection between the device and the pre-embedded reinforcing bars. Pay attention to the height difference between the device and the pre-embedded reinforcing bars. Then, insert the edge protection steel pipe into the sleeve 3 of the device and rotate the first screw 1 to tighten the sleeve 3, ensuring it is fixed to the edge protection steel pipe. This completes the connection and fixation of the device between the pre-embedded reinforcing bars in the beam and the edge protection steel pipe. The importance and practicality of this fixing device in bridge construction effectively solves the problem of edge safety protection.

[0023] In this embodiment, a second screw 5 without a second nut 6 is threadedly connected to the yoke arm 4. This enhances the stability between the guardrail and the yoke arm, reducing the potential risk of loosening.

[0024] In this embodiment, the included angle between a pair of ram's horn arms 4 is set to 20° to 70°, allowing the direction of the guardrail to be flexibly adjusted according to the specific conditions of the bridge and construction requirements, thereby providing a better protective effect.

[0025] In this embodiment, the adjusting assembly consists of an adjusting tube 9, a shaft 8, and a fixing screw 10. The adjusting tube 9 is mounted on the sleeve 3, and the shaft 8, which is inserted and connected to the adjusting tube 9, is mounted on the angle steel 7. The fixing screw 10 is also mounted on the adjusting tube 9 to lock the shaft 8. Thus, the adjusting tube 9 is used to accommodate and adjust the position of the shaft 8, while the fixing screw 10 is used to lock the shaft 8, ensuring its stability in the set position.

[0026] For example Figure 4 As shown, in another embodiment, the fixing screw 10 in the adjusting assembly is replaced by a rotating nut 12, which is threadedly connected to the adjusting tube 9 and rotatably connected to the shaft 8, facilitating adjustment and locking of the shaft's position. By rotating the rotating nut 12 on the adjusting tube 9, the length of the shaft 8 can be easily adjusted, thereby adjusting the position and stability of the guardrail. The rotatable connection between the rotating nut 12 and the shaft 8 ensures that the position of the shaft 8 can be easily locked or unlocked to adapt to different construction requirements.

[0027] For example Figure 3As shown, in another embodiment, the adjusting assembly is composed of the adjusting pipe 9, the shaft rod 8 and the first screw rod 1, and the first screw rod 1 is replaced by the through-resisting edge protection steel pipe, that is, the first screw rod 1 is provided with the adjusting pipe 9 screwing with it at the distal end of the through sleeve 3, and the shaft rod 8 is provided on the angle steel 7 and is rotationally connected with the adjusting pipe 9. By using the through-resisting edge protection steel pipe, the position of the guardrail can be easily adjusted by screwing the adjusting pipe provided at the distal end of the through sleeve with the first screw rod. By rotating the adjusting pipe, the length of the shaft rod can be flexibly adjusted, so that the angle steel is abutted to the embedded steel bars of the beam body, and the connection between the guardrail and the embedded steel bars is stable.

[0028] In the embodiment, the spring 11 is arranged in the adjusting pipe 9 and acts between the first screw rod 1 and the shaft rod 8. The spring 11 provides a buffer between the first screw rod 1 and the shaft rod 8, can absorb the force generated due to external vibration or impact, and reduces the damage or displacement of the guardrail caused by vibration.

[0029] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
