Description

Technical Field

[0001] The utility model relates to a bridge guardrail which is convenient for bridge construction. Background Art

[0002] Bridge guardrails are safety features installed on bridges. Their primary purpose is to prevent vehicles and pedestrians from accidentally falling, while also serving to guide traffic and beautify the bridge environment. The design and material selection of bridge guardrails require consideration of multiple factors, including bridge type, traffic volume, geographic environment, climate conditions, and safety standards.

[0003] During the bridge construction process, it is usually necessary to lift construction materials. When passing through the bridge guardrail, the lifting process is not stable due to various uncertainties at the lifting site, and guardrail columns are often bumped, causing damage to the bridge guardrail columns and making it impossible to install subsequent guardrails. Bridge guardrails are usually installed according to standard heights and are difficult to adjust, resulting in increased guardrail maintenance costs and worker workload during construction, and also increasing the safety risks of bridge construction, posing certain safety hazards. Utility Model Content

Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0026] Reference Figure 1-5 The utility model proposes a bridge guardrail that is convenient for bridge construction, comprising a plurality of embedded holes 2 provided on a bridge deck 1, wherein adjustment columns 3 are inserted into the plurality of embedded holes 2, and mounting columns 4 are provided on the tops of the adjustment columns 3, and a plurality of protection rods 5 are installed between the plurality of mounting columns 4;

[0027] Initial state: the adjustment column 3 is fully inserted into the embedded hole 2, and the installation column 4 and the protection rod 5 are placed above the bridge deck 1;

[0028] Intermediate state: the adjusting column 3, together with the upper mounting column 4 and the protection rod 5, is lifted upward, and the fixing assembly 6 is installed at the bottom of the adjusting column 3. The fixing assembly 6 is fastened to the bottom of the adjusting column 3 and contacts the bridge deck 1;

[0029] Final state: The skirting board 7 is installed between adjacent fixing components 6 and is placed in the middle of the adjustment column 3 .

[0030] In this embodiment, before installing the guardrail, pre-buried holes 2 are first set to ensure that they are evenly distributed on the bridge deck 1. At the beginning, the adjustment columns 3 are inserted into the pre-buried holes 2 to ensure that they are fully embedded, and the installation columns 4 and the protective rods 5 are placed above the bridge deck 1 so that the initial construction can begin. At this time, the bridge construction and other lifting operations above the guardrail will not affect the installation of the guardrail, ensuring that the guardrail will not be damaged by bumps, while expanding the lifting space. When the bridge construction is completed or no lifting is required, the adjustment columns 3, the installation columns 4 and the protective rods 5 are lifted to an appropriate height, and the fixing assembly 6 is added to the bottom of the column. Use the locking bolt 64 to fix it through the locking hole 63 to ensure that the adjustment column 3 is stable and in good contact with the bridge deck 1. Usually, the height of the guardrail above the bridge deck is ensured to be 120 cm, which meets the guardrail installation standard. At this time, there will be a 40 cm gap below. This space is enough to allow children to pass through, so it is necessary to add a skirting board to ensure the safety of the entire guardrail.

[0031] Reference Figure 3 and Figure 5 The fixing assembly 6 includes two fixing ring buckles 61 wrapped around the outer wall of the adjustment column 3, and docking plates 62 extend outward at both ends of the fixing ring buckle 61. A plurality of locking holes 63 are opened on the docking plate 62, and locking bolts 64 are matched in the plurality of locking holes 63. A skirting board clamp 8 matching the skirting board 7 is also provided on one side of the outer wall of the fixing ring buckle 61.

[0032] Specifically, the skirting board clamp 8 includes two clamps 81 arranged on one side of the outer wall of the fixing ring buckle 61. The two clamps 81 are respectively clamped on both sides of the skirting board 7, and a fixing hole 82 is opened on the clamp 81. The skirting board 7 is provided with a corresponding positioning screw hole 71, and a fixing bolt 83 is provided in the fixing hole 82 and the positioning screw hole 71.

[0033] Specifically, the overall height of the mounting column 4 is 80 cm, the height of the adjusting column 3 below is greater than 40 cm, the depth of the embedded hole 2 should be at least greater than the height of the adjusting column 3, and the height of the skirting board 7 should be at least greater than 20 cm and less than the height of the adjusting column 3.

[0034] Specifically, when the adjusting column 3 is lifted, grouting is performed inside the embedded hole 2 , the fixing assembly 6 is fixed to the bottom of the adjusting column 3 until it is completely fixed, and the fixing assembly 6 is moved to the middle position of the adjusting column 3 .

[0035] In this embodiment, after the adjusting column 3 is lifted and fixed, a grouting operation is performed in the embedded hole 2 to further reinforce the position of the adjusting column 3 .

[0036] Specifically, the cross-sectional dimension of the mounting column 4 should be at least larger than the cross-sectional dimension of the embedded hole 2 .

[0037] In this embodiment, a skirting board 7 is installed between the fixing components 6 and fixed with a skirting board clamp 8 to ensure safety and aesthetics. The fixing holes 82 on the skirting board clamp 8 are aligned with the positioning screw holes 71 on the skirting board, and the installation is completed using fixing bolts 83.

[0038] It is worth mentioning that the fixing component 6 can be adjusted in position on the adjustment column 3. The fixing position of the skirting board 7 on the adjustment columns 3 of different lengths is not certain. The fixing component 6 can be adjusted and fixed at any time, and the modular design makes the assembly, adjustment and disassembly of the guardrail very convenient, which provides great convenience for bridge construction and maintenance work.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
