Highway guardrail

Abstract

The invention belongs to the technical field of guardrails, and discloses a highway guardrail for roads. The highway guardrail is mainlycharacterized in that the highway guardrail comprises bottom plates with fixing holes located on two sides, slant support platesare arranged on the inner sides of the two bottom plates, and support side plates are arranged above the two slant support plates;the two support side plates are spaced apart by a certain distance in the horizontal direction, support pipes are fixed above the two support side plates, connecting pipes arearranged at one ends of the support pipes, and end parts of the connecting pipesare inserted into the support pipes; and adapting pipes fixed to the slant support platesarearranged below one ends of the two supportside plates, andplugging pipes fixed to the slant support platesarearranged below the other ends of the two support side plates. When a vehicle collides, the bunt parts of the support side plates are deformed in an inwardly sunken mode, at the same time the slant support plates are also deformed downwards under the pressure of wheels, vehicle kinetic energy is greatly consumed, the damage degree of the vehicle isreduced, and a driver and passengers on the vehicle is prevented from being injured by damage and deformation of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of guardrails, in particular to a guardrail for highways. Background technique [0002] In response to the acceleration of domestic urbanization, the number of cars owned by Chinese urban families is on the rise. As the car enters the homes of ordinary people, while it brings convenient transportation, it also brings many safety problems. The guardrail that uses on the highway at present comprises connecting column and the connecting rod or connecting pipe between connecting column, and connecting column comprises base and upright bar, and base is made of materials such as concrete, and base is placed on the road. The base is heavy, and the connecting rod or connecting pipe is made of metal material. When the vehicle hits quickly, there are the following defects: First, because the base and the connecting rod or connecting pipe have good anti-collision performance, when the vehicle hits, the base and the co...

AI Technical Summary

Problems solved by technology

The base is heavy, and the connecting rod or connecting pipe is made of metal material. When the vehicle hits quickly, there are the following defects: First, because the base and the connecting rod or connecting pipe have good anti-collision performance, when the vehicle hits, the base and the connecting rod or connecting pipe It cannot absorb and consume the kinetic energy of the vehicle, and the damage and deformation of the vehicle are serious, which increases the damage of the vehicle driver and passengers; secondly, the base is generally placed on the road surface, and when the vehicle hits, the base and the connecting rod move and roll to the other side of the road. side, it is easy to cause certain danger to vehicles driving on the other side

Third, the collision will cause the accident car to cross to the opposite side and cause more serious secondary injuries
