1. perishable, easily split because timber has its congenital shortcoming and restriction, except perishable easily split, timber is resource-constrained at home, also various countries all restrict export for environmental protection abroad, so the resource of timber is got being difficult for;

2. the anticorrisive agent of Shi Yonging has toxicity, because the used anticorrisive agent of timber is to adopt the chromaking arsenical copper with toxicity, the constructor there is harm, and anticorrisive agent is difficult to infiltrate through the heart portion of timber, often can't reach the corrosion-resistant code requirement, brings many difficulties to construction;

3. vibration absorption ability is poor, because of folder between metal guardrail board and concrete column is established a cushion block that adopts the timber adding preservative agent to make, almost there is not elasticity, vibration absorption ability is poor, impact resistance is not good enough, very easily makes car travel careless percussion during to the metal guardrail board, stressed greatly, cause the car coverboard depressed phenomenon to occur, the serious people's car that more may cause is injured;

4. be difficult for firmly, because that timber is the metal guardrail board contact surface of microscler square shape and undulate is less, has only part to paste usually and touch, and be easy to drying shrinkage, lax and produce torsion phenomenon, can't finish and agree with one, conjugation built on the sand.

5. unfavorable water and soil and environmental protection because of cushion block uses timber, need cut down forest, destructible the Nature, even harm water and soil and environment.

The purpose of this utility model is that a kind of improved road elastic safety guard fence bumper will be provided, and it is corrosion-resistant, be difficult for splitting, avirulence, and can fit in the metal guardrail board fully and agree with firmly, and shock-resistant ability is strong, and the favourable utilization of resources and environmental protection.

Utility model is achieved in that the guardrail rubber cushion is to mix the shape moulding of complexed metal guardrail board under the high-temperature pressurizing with powder shape scrap tire rubber and viscose glue, guardrail rubber cushion front end top is last straight line, the prominent forward arc body of establishing of last straight-line lower end, the arc body lower ends downward has extended cathetus, the cathetus lower end is equipped with arc body forward, the arc body lower ends downward has extended down straight line, form an identical undulate body with the metal guardrail board, when cathetus is in moulding, be provided with and the metal guardrail board coincide connect airtight and lock and establish the hole that is fixed on the concrete column.

The guardrail rubber cushion can constitute its corresponding body according to the metal guardrail board of different types.

The utility model adopts the rubber mass material, be characterized in not perishable, also be difficult for splitting, and there is not toxicity without anticorrisive agent, it is pulverized with scrap tire rubber again and mixes the high-temperature pressurizing moulding with viscose glue, it is identical shaped to cooperate wave body metal guardrail board to make, thus its contact surface can fit fully, and agree with firm, its plasticity height of mat again, can moulding in response to different metal guardrail board patterns, therefore quite agree with firm and make things convenient for its waste material that has drawn from installing, not only material source is abundant, and be twice laid, the both favourable utilization of resources can take into account environmental protection again, the member of its rubber mass, have the ability that stronger absorption is impacted, thereby can bear powerful the impact, and can alleviate the injury of people's car.
