Description

Technical Field

[0001] This utility model relates to the technical field of adjustable guardrails based on prefabricated bridges, specifically an adjustable guardrail based on prefabricated bridges. Background Technology

[0002] Precast bridges are a type of bridge constructed differently from traditional methods such as steel reinforcement binding and concrete pouring. They are constructed by prefabricating components in a precast component factory, then transporting them to the construction site for hoisting and assembly into the main body of the bridge. The guardrails of precast bridges refer to the guardrails installed on the bridge. According to their location, they can be divided into bridge side guardrails, bridge central divider guardrails, and guardrails at the pedestrian and vehicle lane boundaries. Their purpose is to prevent out-of-control vehicles from going off the bridge, and they have the functions of preventing vehicles from breaking through, passing under, or overturning the bridge, as well as beautifying the bridge structure.

[0003] However, it still has some drawbacks. For example, the guardrails of precast bridges are mostly connected as one piece. If an accident occurs and some guardrails are damaged, many guardrails need to be removed for repair and replacement. Also, during construction, guardrails of different heights are selected to be built according to the actual situation of the bridge, but the existing guardrails are all of fixed height and cannot be adjusted.

[0004] To address the aforementioned issues, this application proposes an adjustable guardrail based on prefabricated bridges. Utility Model Content

[0023] In this embodiment, as Figures 3-4As shown, the support mechanism 7 includes a round rod 17, a sleeve 18, a movable block 19, a movable hole 20, a trigger 21, a telescopic rod 22, a spring 23, a threaded hole 24, a bolt 25, a fixing plate 26, a threaded hole 27, and a cover 28. The sleeve 18 is fixedly connected to the outer surfaces of both ends of the round rod 17. The movable block 19 is movably connected to the inner wall of the sleeve 18. The movable hole 20 is opened on the outer surface of the front end of the sleeve 18. The trigger 21 is movably connected to the inner wall of the movable hole 20. By pulling the trigger 21, the movable block... 19 retracts, then aligns the movable block 19 with the insertion hole 19 of the column 8 and the insertion hole 315 of the movable rod 14. This allows the support mechanism 7 to be installed between the column 8 and the movable rod 14. Pulling the trigger 21 again will remove the support mechanism 7. A telescopic rod 22 is fixedly connected to one side of the outer surface of the trigger 21. A spring 23 is sleeved on the outer wall of the telescopic rod 22. The spring 23 allows the movable block 19 to return to its original position. There are four sets of sleeves 28, movable block 19, movable hole 20, trigger 21, telescopic rod 22, and spring 23. The outer surface of the front end of sleeve 18 has a threaded hole 24. A bolt 25 is threaded onto the inner wall of threaded hole 24. The cover 28 can be fixed to sleeve 18 using bolt 25.

There are eight sets of threaded holes 24, bolt 25, fixing plate 26, and threaded holes 27. A cover 28 is fixedly connected to one side of the outer surface of fixing plate 26. A trigger 21 is fixedly connected to one end of movable block 19. Bolt 25 is threaded on the inner wall of sleeve 27. First, unscrew bolt 25 and remove cover 28 from the outer shell of sleeve 218. Then, pull trigger 21 to place the support mechanism 7 between the two adjacent columns 8 and movable rod 14, so that movable block 19 is aligned with insertion hole 9 on column 8 and insertion hole 15 on movable rod 14. Release trigger 21 to insert movable block 19 into insertion hole 9 and insertion hole 15, so that support mechanism 7 is fixed between column 8 and movable rod 14. Then, use bolt 25 to fix cover 28 to the outer shell of sleeve 218.

[0024] Working principle:

[0025] In the use of an adjustable guardrail based on a precast bridge, the base 1 is first fixed to the bridge at equal intervals using concrete or other methods. The base plate 4 is then fixed to the base 1 using bolts 1-3. The height of the guardrail can then be adjusted. First, unscrew the nut 13 from bolt 2-12, then remove bolt 2-12 from sleeve 1-10. By moving the movable rod 14 within sleeve 1-10, align the insertion hole 4-16 on the movable rod 14 with the insertion hole 2-11 on sleeve 1-10. The height can be adjusted by selecting different insertion holes 4-16. Finally, insert bolt 2-12 into insertion hole 2-11 of sleeve 1-10, then screw the nut 13 onto bolt 2-12 and tighten it to the outer shell of sleeve 1-10. This successfully adjusts the height of the device. After fixing two adjacent adjustment mechanisms 6… Now you can install the support mechanism 7. First, unscrew bolt 325, remove cover 28 from the outer shell of sleeve 218, then pull trigger 21 to place the support mechanism 7 between the two adjacent columns 8 and the movable rod 14, aligning the movable block 19 with the insertion hole 19 on the column 8 and the insertion hole 315 on the movable rod 14. Release trigger 21 to insert the movable block 19 into the insertion hole 19 and the insertion hole 315, thus fixing the support mechanism 7 between the column 8 and the movable rod 14. Then, use bolt 325 to fix cover 28 to the outer shell of sleeve 218. This completes the installation of the device. By continuing to connect the installation devices on both sides of the device, an integrated guardrail can be built on the bridge. When the guardrail is accidentally damaged, the damaged part can be disassembled and replaced with a new one according to the above steps.

[0026] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
