Description

Technical Field

[0001] The utility model belongs to the technical field of traffic protection fences, and in particular relates to a corrugated guardrail with a buffering function. Background Art

[0002] With the continuous development of modern society and the continuous improvement of people's living standards, the number of cars owned in the country is gradually increasing, and the domestic infrastructure construction is also gradually improving. As a public facility necessary for modern travel, the main function of highways is to facilitate the driving of vehicles and the walking of pedestrians, and to facilitate travelers to reach their destinations accurately. In order to ensure the safety of vehicle travel, guardrails are usually set on both sides of the highway for blocking.

[0003] Most of the existing highway guardrails are single-layer steel structure plates without corresponding buffer facilities. When a traffic accident occurs, vehicles often crash into the guardrails on both sides of the highway, which will largely destroy the vehicles; and the rigid collision impact will also cause impact injuries to the driver and passengers. Utility Model Content

[0004] The utility model provides a corrugated guardrail with a buffering function. When a vehicle has a traffic safety accident, the corrugated guardrail can absorb energy by virtue of its elastic buffering. The guardrail is not easily destroyed and can provide good protection for the vehicle and the driver and passengers.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a corrugated guardrail with a buffering function, which comprises:

[0006] Inner baffle;

[0007] An extension plate, the extension plate is integrally connected to both sides of the inner baffle plate and extends outward, and the thickness of the extension plate gradually decreases;

[0008] An outer baffle, the outer baffle being integrally connected to a side of the extension plate away from the inner baffle;

[0009] A first shock absorbing plate is integrally connected to a side of the outer baffle plate away from the extension plate.

[0010] Optimally, the material is a glass fiber reinforced composite material, a carbon fiber reinforced composite material, an aramid fiber reinforced composite material or a basalt fiber composite material.

[0011] Optimally, the outer baffle is arc-shaped, and one side of the outer baffle is tangent to the extension plate, and the other side of the outer baffle is tangent to the first shock-absorbing plate.

[0012] Optimally, it also includes a first outer reinforcing plate, a second outer reinforcing plate and an inner reinforcing plate integrally connected to the outer baffle plate on one side close to the arc center, and the first outer reinforcing plate and the second outer reinforcing plate are symmetrically arranged on both sides of the inner reinforcing plate.

[0013] Optimally, the first outer reinforcing plate is perpendicular to the extension plate, the second outer reinforcing plate is perpendicular to the first shock-absorbing plate, and a line connecting the first outer reinforcing plate and the second outer reinforcing plate passes through the arc center of the outer baffle.

[0014] Optimally, it also includes a transition portion arranged at the connection between the inner baffle plate and the extension plate, a second shock-absorbing plate integrally connected to the first shock-absorbing plate on the side away from the outer baffle plate, and broken holes that pass through the extension plate and the first shock-absorbing plate at intervals.

[0015] Optimally, the thickness of the extension plate at its widest point is equal to the thickness of the inner baffle plate, and the thickness of the extension plate at its narrowest point is equal to the thickness of the outer baffle plate.

[0016] Optimally, the outer baffle plate, the first shock absorbing plate and the second shock absorbing plate have the same thickness.

[0017] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0018] The utility model is a corrugated guardrail with a buffering function. It is made of composite materials. By setting an extension plate with a gradually decreasing thickness, when a vehicle has a traffic safety accident, the corrugated guardrail can absorb energy by virtue of its elastic buffering. The guardrail is not easily destroyed and can provide good protection for the vehicle and the driver and passengers.

[0019] Since the two sides of the outer baffle are tangent to the extension plate and the first shock-absorbing plate respectively, the impact force will be directly applied to the inner baffle through the extension plate, and will not be applied to the connection between the extension plate and the outer baffle, thus preventing the connection between the outer baffle and the extension plate from breaking first;

[0020] When a more serious traffic accident occurs, the corrugated guardrail will first break from the broken hole, and then the entire piece will fall off the side of the guardrail. It will not break into multiple small pieces and fly towards the driver and passengers, thus avoiding secondary injuries to the driver and passengers. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0027] like Figure 1-3 The figure shows a schematic diagram of a corrugated guardrail with a buffering function of the utility model. The corrugated guardrail is usually fixedly installed on both sides of the highway. When a vehicle traffic safety accident occurs, the corrugated guardrail absorbs energy by virtue of its elastic buffering. The guardrail is not easily destroyed and can provide good protection for vehicles and drivers and passengers. The corrugated guardrail includes an inner baffle plate 1, an extension plate 2, a transition portion 3, an outer baffle plate 4, a first damping plate 5, a second damping plate 6, a first outer reinforcing plate 7, a second outer reinforcing plate 8, an inner reinforcing plate 9, a broken hole 10, an inner deformation groove 11 and an outer deformation groove 12.

[0028] The material of the corrugated guardrail is glass fiber reinforced composite material, carbon fiber reinforced composite material, aramid fiber reinforced composite material or basalt fiber composite material. The corrugated guardrail made of composite material is light in weight, convenient for transfer, transportation and subsequent installation; and the composite material has high strength. When a safety accident occurs, it can effectively absorb the vibration energy generated by the safety accident. The guardrail is not easily destroyed and can provide good protection for vehicles and drivers and passengers.

[0029] The extension plate 2 is integrally connected to both sides of the inner baffle 1 and extends outward (i.e., the distance between the two extension plates 2 gradually increases). The thickness of the extension plate 2 gradually decreases, i.e., the thickness of the extension plate 2 on the side close to the inner baffle 1 is greater than the thickness of the extension plate 2 on the side away from the inner baffle 1. Since the side of the extension plate 2 away from the inner baffle 1 is thinner, the side of the extension plate 2 away from the inner baffle 1 has higher elasticity. When a traffic safety accident occurs to the vehicle, it will first contact the side of the extension plate 2 away from the inner baffle 1. Since the elasticity here is higher, it can absorb more vibration energy generated by the safety accident.

[0030] The thickness of the extension plate 2 near the inner baffle 1 is larger, so the strength here is higher. When a traffic safety accident occurs to the vehicle, the side of the extension plate 2 away from the inner baffle 1 will first come into contact, and then the impact force will act on the root of the extension plate 2, that is, the side of the extension plate 2 near the inner baffle 1. Since the thickness here is larger and the strength is higher, it is not easy to break, avoiding the hidden danger of the inner baffle 1 breaking to the driver and passengers.

[0031] The thickness of the widest part of the extension plate 2 is equal to the thickness of the inner baffle 1, and a transition portion 3 is provided at the connection between the extension plate 2 and the inner baffle 1. By providing the transition portion 3, both the inner and outer sides of the connection between the extension plate and the inner baffle 1 are smoothly transitioned in an arc shape. This improves the structural strength of the connection between the two, and prevents the connection from breaking when impacted by external forces; and the arc-shaped transition portion 3 eliminates the sharp corner structure, so even if a serious car accident occurs and the inner baffle 1 breaks, the arc-shaped transition portion 3 will not cause secondary scratches or punctures to the driver and passengers.

[0032] The outer baffle plate 4 is integrally connected to the side of the extension plate 2 away from the inner baffle plate 1, that is, the outer baffle plate 4 is integrally connected to the side of the extension plate 2 with the smallest thickness. The thickness of the extension plate 2 at the narrowest part is equal to the thickness of the outer baffle plate 4, ensuring that the force at the connection between the outer baffle plate 4 and the extension plate 2 is more uniform, and when a traffic safety accident occurs to the vehicle, the connection between the outer baffle plate 4 and the extension plate 2 is prevented from being broken first.

[0033] The outer baffle plate 4 is arc-shaped, and the arc center of the outer baffle plate 4 faces the inner baffle plate 1. The first damping plate 5 is integrally connected to the side of the outer baffle plate 4 away from the extension plate 2. Figure 3 As shown, the inner side of the outer baffle plate 4 is tangent to the extension plate 2 , and the outer side of the outer baffle plate 4 is tangent to the first shock-absorbing plate 5 .

[0034] When a traffic safety accident occurs to the vehicle, it will first come into contact with the outer baffle plate 4. Since the thickness here is relatively thin, its elasticity is relatively high, so it can absorb more vibration energy generated by the safety accident; since the two sides of the outer baffle plate 4 are tangent to the extension plate 2 and the first shock-absorbing plate 5 respectively, the impact force will be directly applied to the inner baffle plate 1 through the extension plate 2 (and the impact force will not be applied to the connection between the extension plate 2 and the outer baffle plate 4, avoiding the connection between the outer baffle plate 4 and the extension plate 2 from breaking first). Since the thickness of the inner baffle plate 1 is relatively large and the strength is higher, it is not easy to break, avoiding the hidden danger of the break of the inner baffle plate 1 to the driver and passengers.

[0035] Attached Figure 3 What is shown is a three-stage corrugated guardrail. In actual production, the number of inner baffles 1 and outer baffles 4 can be appropriately increased or decreased according to the height of the highway road surface, thereby making a four-stage or two-stage corrugated guardrail.

[0036] The first outer reinforcing plate 7 and the second outer reinforcing plate 8 are integrally connected to one side of the outer baffle plate 4 close to the arc center, and the connecting line of the first outer reinforcing plate 7 and the second outer reinforcing plate 8 passes through the arc center of the outer baffle plate 4. Figure 3 As shown, the first outer reinforcing plate 7 is perpendicular to the extension plate 2 , and the second outer reinforcing plate 8 is perpendicular to the first damping plate 5 .

[0037] When the corrugated guardrail is actually fixed and installed, the inner baffle 1 is fixed on both sides of the highway road surface, and the curved outer baffle 4 faces the center of the road (that is, when a traffic safety accident occurs, the vehicle will first contact the curved outer baffle 4). In order to ensure that the curved outer baffle 4 has a higher elastic buffer to absorb more impact energy, the thickness of the outer baffle 4 is relatively thin, but this will also reduce the structural strength of the outer baffle 4.

[0038] Even if the thickness of the narrowest part of the extension plate 2 is designed to be the same as the thickness of the outer baffle plate 4, there is still a risk of premature fracture at the connection between the extension plate 2 and the outer baffle plate 4 when a traffic safety accident occurs. Figure 3 As shown, by providing a first outer reinforcing plate 7 at the connection between the extension plate 2 and the outer baffle plate 4, and providing a second outer reinforcing plate 8 at the connection between the outer baffle plate 4 and the first damping plate 5, the problem of low strength caused by the thin thickness of the outer baffle plate 4 is compensated.

[0039] The connecting line of the first outer reinforcing plate 7 and the second outer reinforcing plate 8 passes through the arc center of the outer baffle 4 and is perpendicular to the extension plate 2 or the first damping plate 5. This can improve the structural strength of the arc connecting the outer baffle 4 and the extension plate 2, and at the same time improve the structural strength of both sides of the outer baffle 4.

[0040] The inner reinforcing plate 9 is integrally connected to one side of the outer fender 4 near the arc center, and the first outer reinforcing plate 7 and the second outer reinforcing plate 8 are symmetrically arranged on both sides of the inner reinforcing plate 9. The inner reinforcing plate 9 can improve the structural strength at the center of the outer fender 4. When a traffic accident occurs, the vehicle will first contact the outer fender 4 to avoid directly breaking the outer fender 4 from the center of the outer fender 4.

[0041] The second shock absorbing plate 6 is integrally connected to a side of the first shock absorbing plate 5 away from the outer baffle plate 4 and extends inwardly. The second shock absorbing plate 6, the first shock absorbing plate 5 and the outer baffle plate 4 have the same thickness to improve the elasticity of the outermost side of the corrugated guardrail.

[0042] The inner deformation groove 11 is arranged on the inner side of the extension plate 2, and the outer deformation groove 12 is arranged on the outer side of the extension plate 2. When a traffic accident occurs, the vehicle will first contact the outer baffle plate 4. The inner deformation groove 11 and the outer deformation groove 12 ensure that the outer baffle plate 4 has space to deform inward, thereby absorbing energy.

[0043] like Figure 1 , 2As shown, the broken holes 10 penetrate the extension plate 2 and the first shock-absorbing plate 5, and are arranged at intervals. The arrangement of the broken holes 10 makes the overall structural strength of the surface of the corrugated guardrail not completely the same, and the strength of the corrugated guardrail near the broken holes 10 is relatively low. In the event of a serious traffic accident, the corrugated guardrail will first break from the broken holes 10, and then the whole piece will fall off the side of the guardrail to avoid secondary damage to the driver and passengers (if there is no broken hole 10 on the corrugated guardrail, the overall structural strength of the surface of the corrugated guardrail is consistent. In the event of a serious traffic accident, the corrugated guardrail will break into multiple small fragments and fly towards the driver and passengers, causing secondary damage to the driver and passengers).

[0044] The corrugated guardrail with buffering function of the utility model is provided with an extension plate 2 with a gradually decreasing thickness. When a vehicle has a traffic safety accident, it will first contact the outer baffle plate 4. Since the thickness here is relatively thin, its elasticity is relatively high, and it can absorb more vibration energy generated by the safety accident to prevent the vehicle from being damaged; since the thickness of the inner baffle plate 1 is relatively large and the strength is higher, it is not easy to break, and the breakage of the inner baffle plate 1 will avoid the hidden danger to the driver and passengers;

[0045] Since the two sides of the outer baffle plate 4 are tangent to the extension plate 2 and the first shock-absorbing plate 5 respectively, the impact force will be directly applied to the inner baffle plate 1 through the extension plate 2 (and the impact force will not be applied to the connection between the extension plate 2 and the outer baffle plate 4, thus avoiding the connection between the outer baffle plate 4 and the extension plate 2 from breaking first);

[0046] The setting of the broken hole 10 makes the overall structural strength of the corrugated guardrail surface not completely the same. The strength of the corrugated guardrail near the broken hole 10 is relatively low. When a more serious traffic accident occurs, the corrugated guardrail will first break at the broken hole 10, and then the entire piece will fall from the side of the guardrail, avoiding secondary injuries to the driver and passengers.

[0047] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
