Description

Technical Field

[0001] The utility model belongs to the technical field of highway anti-collision facilities, and in particular relates to an anti-collision guardrail for highway safety. Background Art

[0002] The setting of highway crash barriers plays a great role in preventing traffic accidents. If the height of the crash barriers is too high, then when hit, the contact area with the vehicle is large and the center height of the contact is high, and the bottom of the crash barriers will be subjected to greater shear stress; if the height of the crash barriers is too low, it cannot form effective protection, and the vehicle is likely to fly out from above the guardrail. When a vehicle is driving to the right and tilts to hit the crash barriers, part of the railings is subjected to a greater impact force, and the remaining railings do not contact the vehicle, resulting in only part of the railings forming an effective blocking and anti-collision effect, which cannot effectively block the vehicle. Therefore, it is urgent to develop a highway safety crash barrier that is suitable for vehicles driving to the right and tilting to hit the crash barriers and can withstand a large impact force.

The upper end of the straight support column 21 is fixedly connected to the lower end of the upper base 12 of the guardrail, and the lower end of the straight support column 21 is installed on a horizontal plane. The upper end of the oblique support column 22 is fixedly connected to the lower end of the upper base 12 of the guardrail, and the lower end of the oblique support column 22 is installed on a horizontal plane.

[0033] like Figure 2 As shown, the support column mechanism 2 further includes a support column connecting rib 23 , and both ends of the support column connecting rib 23 in the length direction are fixedly connected to the positive support column 21 and the oblique support column 22 respectively.

[0034] like Figure 3 and Figure 4 As shown, the anti-collision guardrail for highway safety also includes a lower guardrail rod mechanism 3, which includes a lower guardrail arc component 31. The lower guardrail arc component 31 is arc-shaped. There are multiple lower guardrail arc components 31, and the multiple lower guardrail arc components 31 are all installed on the guardrail lower base 11. The multiple lower guardrail arc components 31 are evenly distributed along the length direction of the guardrail lower base 11.

The arc shape has a better anti-collision effect and improves safety. At the same time, the length direction of the oblique support top column 22 is perpendicular or nearly perpendicular to the vehicle impact surface, which can play a better anti-collision role. The impact force is transmitted to the side of the guardrail upper base 12 through the vehicle impact surface and then to the positive support top column 21 and the oblique support top column 22. The guardrail lower base 11, the positive support top column 21 and the oblique support top column 22 are buried in the ground for support, so they can withstand greater impact force and greatly improve safety.
