Description
Technical Field
The utility model relates to a special section bar technical field, in particular to rail guard is with strengthening abnormal shape pipe assembly.
Background
The anti-collision guardrail structure is used as basic safety facilities on the highway, and plays an important role in guaranteeing the traffic safety of the highway. The existing highway guardrails mostly adopt the main form of semi-steel guardrails, are usually arranged in the middle or at two sides of a highway, and are of a continuous structure formed by splicing corrugated steel guardrail plates and supporting the corrugated steel guardrail plates by solid upright posts. When the guardrail is collided, the collision kinetic energy is absorbed only by the friction force of the surface of the corrugated steel guardrail plate and the elasticity of the corrugated steel guardrail plate, and the damping time is short in actual collision, so that the guardrail has a poor effect of absorbing the collision energy to decelerate the vehicle, basically only plays a role of stopping the vehicle from rushing out of a road, and has little effect on reducing the damage to the vehicle and drivers and passengers.
The most effective means for improving the safety factor of the road is to decelerate the vehicle by absorbing collision energy through the protective guard in special occasions (such as high-speed running road sections of a racing yard). It is therefore desirable to design a structure capable of effectively absorbing the kinetic energy of vehicle collision instead of the conventional corrugated steel balustrade panel.
Disclosure of Invention
The utility model provides an above-mentioned technical problem provides a rail guard is with strengthening mechanical tubes subassembly, has the characteristics that can absorb vehicle striking kinetic energy and non-deformable in a large number, especially is applicable to on the straight line section that traveles at a high speed.
The utility model comprises the following technical scheme: a reinforced special pipe assembly for a protective guard comprises a front baffle and a mounting back plate, wherein the front baffle is of a double-layer plate structure, and a metal net fixedly provided with reinforcing ribs is clamped between the double-layer plates; the section of the front baffle is corrugated, a group of supporting plates are arranged between the wave crest of the front baffle and the mounting back plate and between the wave trough of the front baffle and the mounting back plate for connection, and the supporting plates are perpendicular to the mounting back plate; elastic materials are filled on two sides of each group of supporting plates; the special pipe is installed on the guard rail through the installation back plate.
Furthermore, the reinforcing ribs are arranged at the wave crests of the cross section of the front baffle, and the wave crests are preferentially contacted with a vehicle when a traffic accident is collided, so that the required structural strength is maximum at the positions.
Furthermore, a luminous anti-slip strip is attached to the peak of the cross section of the front baffle.
Furthermore, the front baffle and the mounting back plate are welded into a whole through two elastic metal strips.
Furthermore, the reinforcing ribs are also arranged at the wave troughs of the cross section of the front baffle plate.
Furthermore, a long-strip-shaped air bag is installed at the trough of the section of the front baffle.
Furthermore, the long-strip-shaped air bag is provided with a separating sheet at regular intervals, so that the failure of the whole air bag caused by the breakage of one or more air bags is prevented.
The utility model has the advantages and positive effect:
1. the utility model discloses a mechanical tubes that preceding baffle and installation backplate are constituteed replaces traditional corrugate steel guardrail board, and the upper and lower both ends and the back of mechanical tubes are the plane, are convenient for install on the guardrail stand, and can use by a plurality of mechanical tubes combinations.
2. The utility model discloses a be equipped with backup pad and elastic material between preceding baffle and the installation backplate to the impact that dispersion mechanical tubes shell body part received.
3. The utility model discloses a preceding baffle adopts bilayer structure, and the centre is equipped with the metal mesh of adorning the strengthening rib admittedly and absorbs collision kinetic energy, makes the difficult breakage of preceding baffle in order to cause the injury to vehicle and driver and passenger.
