Corrugated protective fence for expressway

Abstract

The invention relates to the technical field of traffic equipment, and discloses a corrugated protective fence for expressways, which comprises a stand column, the middle part of the stand column is fixedly sleeved with a fixing bolt, one side of the stand column is provided with a corrugated plate, and the middle part of the corrugated plate is movably sleeved with one end of the fixing bolt; the end of the fixing bolt movably sleeved with the corrugated plate is in threaded connection with a fixing nut, and the side faces of the upper end and the lower end of the corrugated plate are fixedly connected with supporting rods. The buffer rubber parts are arranged on the surfaces of the upper convex end and the lower convex end of the corrugated plate, so that the upper convex end and the lower convex end of the corrugated plate can be effectively protected, an effective buffer effect is provided for the upper convex end and the lower convex end of the corrugated plate, and the damage degree of the corrugated plate is reduced; and meanwhile, supporting rods are arranged at the upper and lower ends of the corrugated plate, so that the supporting rods are movably sleeved with the stand column; and the component force rods can effectively disperse the backward impact force of the supporting rods on the stand columns, the damage degree of the stand columns is reduced, and meanwhile the connectivity and stability between the corrugated plates and the stand columns are improved.

Description

technical field [0001] The invention relates to the technical field of traffic equipment, in particular to a corrugated protective fence for expressways. Background technique [0002] Traffic guardrail is a kind of traffic safety facility installed on the outside of the road, traffic separation strip and sidewalk curb. With the widespread use of cars, the types of traffic guardrails used to ensure traffic safety are also increasing. Among them, the corrugated guardrail Widely used in highways, it is a continuous structure that is spliced ​​with corrugated guardrails and supported by columns. It uses the deformation of the guardrails, columns and fixed bases to absorb collision energy and force out-of-control vehicles to change direction and return to The normal driving direction prevents the vehicle from rushing out of the road, so as to protect the safety of the vehicle and passengers and reduce the loss caused by the accident. [0003] However, the corrugated plate part o...

Problems solved by technology

[0003] However, the corrugated plate part of the existing corrugated guardrail is made of steel materials. When the vehicle and the guardrail plate collide rigidly, although the corrugated guardrail effectively prevents the vehicle from continuing to deviate from the track, the collision position of the guardrail and the vehicle It also caused serious damage, especially the two parts of the corrugated plate and the column. Since the upper and lower convex ends of the corrugated plate are more protruding than the middle position, the upper and lower convex ends are always subjected to the impact force of the car, causing serious deformation of the corrugated plate. The column is subjected to the backward impact energy of the corrugated plate as a whole, causing the column to fall backwards and the column is seriously damaged. At the same time, it is also very easy to cause the phenomenon that the column and the corrugated plate are not tightly connected, unstable, and easy to fall off.
