Problems solved by technology

Because the speed of the car is faster on the expressway, when an accident occurs, the collision between the car and the guardrail is stronger, so the ordinary guardrail is very easy to be damaged, and the impact force will not be reduced, so that the guardrail cannot be lifted. to its protective

Embodiment Construction

[0012] Combine below figure 1 Specific description embodiment:

[0013] An inner wing of a high-speed guardrail is characterized in that the inner wing of the high-speed guardrail includes a wing body 1, and the wing body 1 shrinks gradually from the head to the tail, and the wing body 1 includes a shell 2 and a hollow body. Cavity 3, the cavity 3 is provided with a number of internal ribs 4, the internal ribs 4 are S-shaped, and the R angle 5 of the tail of the wing body 1 is 0.5-0.7 degrees.

[0014] Preferably, the shell is processed by extruding PVC resin through toughening and modifying formula.

[0015] Preferably, the thickness of the outer shell is 2.5-3.0mm, and the thickness of the inner rib is 0.8-1.0mm.

[0016] When the inner wing of the high-speed guardrail provided by the present invention is in use, the entire inner wing is arranged inside the outer wing, so that the inner wing and the outer wing are closely connected. The wing body gradually shrinks from th...

Abstract

The invention belongs to the technical field of guardrail appliances, and particularly relates to an inner fin of a highway guardrail. The inner fin is characterized by comprising a fin body; the fin body is reduced gradually from the head to the tail and comprises a shell and a cavity; a plurality of inner ribs which are S-shaped are arranged in the cavity, and the R-angle of the tail of the fin body ranges from 0.5 degree to 0.7 degree. The inner fin can be matched with an outer fin to absorb external impact and bear high-intensity impact, so that the safety performance of the whole guardrail is improved.

Description

technical field [0001] The invention belongs to the technical field of guardrail appliances, in particular to an inner wing of a high-speed guardrail. Background technique [0002] Guardrails are mainly used for the protection and protection of equipment and facilities in roads, factories, workshops, warehouses, parking lots, commercial areas, public places and other occasions. Guardrails can be seen everywhere in our lives. Guardrails are generally used in conjunction with columns. The columns of the guardrail are fixed to the ground by expansion bolts. It is usually installed on both sides of the road, around the production equipment, building corners, both sides of the door and the edge of the cargo platform, etc. The general guardrail is made of steel. This type of guardrail has this defect, especially when being applied to the highway, its defect is more obvious. Because the speed of the car is faster on the expressway, when an accident occurs, the collision betwee...
