Shock absorber using waste tires {SHOCK ABSORBING DEVICE USING WASTE TIRES}

The present invention relates to a shock absorbing device using waste tires, and more particularly, made of waste tires, waste vinyl, waste styrofoam, waste PE-based products, and the like, while forming an air layer therein, The present invention relates to a shock absorbing device using waste tires configured to use a shock absorbing rail having a reinforcing plate for providing a space portion as a guard rail, a median separator, a shock absorbing table, and an anti-glare net.

In places with heavy traffic, such as highways and national highways, central dividers are installed to prevent collisions with vehicles traveling in opposite lanes. The upper part of the central separator is further equipped with an anti-glare net to block the light emitted from the headlights of the opposite vehicle for safe operation. In addition to the central separator, guardrails are provided on the roads and bridges where many traffic passes, to protect vehicles that are thrown or rolled over the roadside. Shock absorbers are installed.

Conventional center separators and guard rails are usually made of galvanized steel sheet, and the rails are tensioned during a vehicle crash to prevent the vehicle from overturning and falling.

However, in the case of a conventional guard rail or a center separator made of steel sheet, the amount of reflected impact transmitted to the vehicle in the event of a crash is large, and since the strut and the rail steel sheet are both subjected to the impact generated during the crash, the strut is twisted or conducted. It will cause a car accident. In addition, the conventional shock absorber installed on the inside or outside of the steep curve of the hill slope is prepared for the crash accident by using the prototype of the waste tire as it is, but due to the high repulsive force of the waste tire delivered during the collision of the vehicle It causes a second collision with the vehicle in the lane, which in turn impedes safe driving. In addition, the conventional anti-glare net installed on the central separator or shock absorber is made of galvanized steel or PE (polyethylene), so it is likely to cause a second accident while being damaged by the impact transmitted from the vehicle in the event of an impulse, especially The mesh made of galvanized steel has a problem in that it causes a great obstacle to safe operation because the light of the other vehicle enters through the gap generated while being torn or bent and obstructs the driver's vision.

The present invention for solving the above problems is made of waste tires, waste vinyl, waste styrofoam, waste PE-based products, etc., and form an air layer therein, and add a reinforcement plate to provide an air space while being deformed during impact. When the air layer and the air space part acts as an air bag due to atmospheric pressure in the event of a collision, the guard rail or central separator composed of a shock absorbing rail that can actively absorb the impact generated during the collision to reduce the damage caused by the accident, An object of the present invention is to provide a shock absorber using a waste tire for shock absorber.

Another object of the present invention is to separate the support plate for fixing the shock-absorbing rail at the time of impact, and at the same time to transmit the shock wave to the adjacent rail to reduce the amount of impact applied to the support, in particular, the center separator In the case of using, the present invention provides a shock absorber using waste tires configured to reduce the amount of impact through interaction with the opposite lane rail.

Another object of the present invention is to provide a shock absorbing device using a waste tire that can prevent the anchor bolt is dropped by the impact by adopting a fixing method by the anchor bolt is separated from the anchor bolt fixing portion and the support. have.
