Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and in particular to a telescopic protective plate. Background Technology

[0002] Bridge guardrails are mainly used to cover the gaps in the crash barriers at both ends of bridge expansion joints. The general shape of the guardrails is consistent with or similar to the shape of the crash barriers, and the materials and specific dimensions are determined by the design drawings. Installation is generally determined by the situation. When the crash barrier is not yet poured, it is usually fixed by welding steel bars; or after the crash barrier has been poured, it is usually installed by drilling holes and using expansion bolts.

[0003] Existing bridge guardrails are generally flat structures, such as the concrete crash barrier device disclosed in application number 202510498195.5. The two sides of the guardrail are connected to the left and right sides of the crash barrier. This type of guardrail mainly relies on the contraction of the metal plate to accommodate the deformation of the expansion joint. However, the crash barrier is subjected to greater stress, and this type of guardrail cannot meet the expansion and contraction deformation requirements of the expansion joint between the two crash barriers.

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] This embodiment provides a telescopic protective plate, such as Figures 1-7As shown, it includes a first connecting plate 1, a second connecting plate 2, and a telescopic plate 3. The first connecting plate 1 and the second connecting plate 2 are respectively connected to the left and right sides of the telescopic plate 3 and are respectively connected and fixed to the anti-collision walls at both ends. The telescopic plate 3 can extend and retract laterally and adjust the distance between the first connecting plate 1 and the second connecting plate 2.

[0029] In this embodiment, the telescopic protective plate 3 is installed at the expansion joint between the two crash barriers to accommodate the expansion and contraction of the joint. The first connecting plate 1 and the second connecting plate 2 are respectively connected to the crash barriers on both sides of the expansion joint, ensuring the expansion and contraction of the bridge crash barriers and their aesthetic appeal and effectiveness.

[0030] The telescopic protective plate in this embodiment has good deformation capacity, which allows it to adapt to curves, slopes, etc., and can be applied to complex terrain such as mountain roads and bridges.

[0031] As a preferred embodiment, such as Figure 1 As shown, the telescopic plate 3 is a corrugated telescopic plate 3, with the corrugations extending laterally and remaining consistent vertically. The corrugations of the telescopic plate 3 can have a V-shaped structure laterally, such as... Figure 3 As shown; the corrugations of the telescopic plate 3 can also be two V-shaped structures in the transverse direction, such as... Figure 1 As shown; the corrugations of the telescopic plate 3 can also have multiple V-shaped structures in the transverse direction, such as... Figure 4 As shown, corrugated expansion joints have good expansion and contraction capabilities, allowing them to adjust their width according to changes in expansion joints. This adapts to variations in expansion joint width, reduces stress on the crash barrier, and provides better protection.

[0032] In addition, the telescopic plate 3 is a corrugated telescopic plate 3, which makes it aesthetically pleasing. The corrugated lines are adapted to the road and bridge lines, have a visual guidance function, and can also reduce driver visual fatigue, improve driving comfort and safety. Some surface treatments (galvanizing, powder coating, painting, etc.) can also meet the appearance requirements.

[0033] In one preferred embodiment, a plurality of mounting and fixing connection holes 4 are respectively provided on the first connecting plate 1 and the second connecting plate 2. The first connecting plate 1 and the second connecting plate 2 are respectively connected to the crash barrier through the connection holes 4 by connectors. Preferably, the plurality of connection holes 4 are evenly arranged vertically on the first connecting plate 1 and the second connecting plate 2, and the connectors can be bolts.

[0034] In this embodiment, the first connecting plate 1 and the second connecting plate 2 are respectively connected to the anti-collision wall through connectors, making the connection more reliable and the operation simple and convenient.

[0035] In a preferred embodiment, a groove 5 is provided around the connecting hole 4, which is recessed towards the side closest to the crash barrier. When the connector is installed on the crash barrier, it retracts into the groove 5.

[0036] In this embodiment, when the connector is installed on the crash barrier, the countersunk bolt is embedded in the groove 5 to prevent the connector from protruding from the outside of the protective plate and affecting the surrounding environment or vehicle driving.

[0037] In one preferred embodiment, the first connecting plate 1, the second connecting plate 2, and the telescopic plate 3 are an integral structure, giving the telescopic protective plate good strength and allowing it to be formed by bending the sheet metal. Installation is simple and flexible; some components use standard fastening and riveting, enabling quick assembly and fixing, saving construction time and manpower.

[0038] Damaged sections of the telescopic protective panels are easy to replace. When a section is damaged, there is no need for large-scale dismantling; simply replacing the corresponding parts reduces maintenance difficulty and cost.

[0039] In a preferred embodiment, the telescopic protective panel includes a first panel 6 and a second panel 7, with the first panel 6 connected to the top of the second panel 7. The second panel 7 is fitted and connected to the inner side of the crash barrier, and the first panel 6 is fitted and connected to the top surface of the crash barrier.

[0040] like Figure 5 As shown, the first panel 6 and the second panel 7 are connected at an obtuse angle. The lower side of the second panel 7 has a bent structure to accommodate a crash barrier of a certain shape. Figure 6 As shown, the first panel 6 and the second panel 7 are connected and have a chamfer. The lower side of the second panel 7 has a bending structure to accommodate a specific shape of crash barrier.

[0041] In a preferred embodiment, the telescopic protective plate of this embodiment further includes a third panel 8, which is disposed opposite to the second panel 7. The top end of the third panel 8 and the top end of the second panel 7 are respectively connected to the two sides of the first panel 6, and the third panel 8 is attached to the outer side of the crash barrier.

[0042] like Figure 7 As shown, the third panel 8 is arc-shaped. The first panel 6 and the second panel 7 are connected by an arc-shaped connecting section that protrudes inward. The lower side of the second panel 7 has a bent structure to accommodate a specific shape of crash barrier, and the third panel 8 protects the outer side of the crash barrier. The term "inner side" refers to the side closer to the bridge road surface, and "outer side" refers to the side farther from the road surface.

[0043] In a preferred embodiment, the first panel 6, the second panel 7, and the third panel 8 are an integral structure. The first panel 6, the second panel 7, and the third panel 8 form the observation structure of the telescopic protective plate in its longitudinal section, such as... Figure 7As shown, each panel includes a first connecting plate 1, a second connecting plate 2, and a telescopic plate 3. The telescopic plate 3 can be shaped into multiple V-shaped or W-shaped continuous telescopic expansions, or multiple U-shaped or inverted U-shaped continuous telescopic expansions, depending on the amount of bridge expansion.

[0044] The telescopic protective plate in this embodiment can be made of galvanized steel plate, aluminum alloy plate, stainless steel plate, etc., which has good corrosion resistance and can maintain its condition for a long time in harsh environments such as wind, rain, and coastal salt spray, extending its service life and reducing the frequency of replacement. It is highly durable, with high material strength, combining rigidity and flexibility, and is not easily deformed or damaged when exposed to harsh outdoor environments for extended periods, exhibiting good stability. It offers high cost-effectiveness; compared to some guardrails, the material and installation costs are lower, providing a significant advantage for large-scale installations, allowing for cost control while ensuring safety.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
