Abstract

A wave beam ribbed protective barrier capable of reducing potential accident severity of various hitting vehicles is formed by thinning original wave beam steel plate of a wave beam protective barrier which has a structure of sequentially connected support bracket and wave beam and is arranged on a vertical column and adding reinforcing ribs. When a vehicle hits the protective barrier, the wave beam deforms and the movement absorbs impacting vehicle energy, then the vehicle returns to normal running direction and then the impacting vehicle stops; when the vehicle moves towards the protective barrier further, deformed and shifted wave beam contact reinforcing ribs and distributes the impacting force to the reinforcing ribs, rib plates, supporting bracket and vertical column until the impacting vehicle finally stops.

Description

Wave beams reinforcement guardrail

The utility model relates to the vehicle safety fender guard on a kind of highway, and particularly it can alleviate the wave beams reinforcement guardrail of the various collision vehicle latent defect orders of severity.

At present, corrugated beam barrier structure on the known express highway is by column, carriage and wave beams are linked in sequence with bolt and form, it has certain rigidity, and wave beams is passed through in drawing tension and sight line inducing effect, the distortion of carriage absorbs collision vehicle energy, aesthetic in appearance, be difficult for accumulated snow in the cold district use, damage parts and change all very desirable easily.But, " express highway corrugated beam steeled protection fence (product standard) " that this guardrail was formulated according to nineteen ninety-five, total mass are decided to be that the medium-sized collision vehicle design of 10t formulates, for heavy type collision vehicle, its intensity is little, support the incessantly collision of heavy-duty vehicle of resistance, in this case, should strengthen the intensity of guardrail, comprise: reduce the column spacing, strengthen the column size, middle anchoring and raising wave beams rigidity just can stop the collision vehicle to run off outside the road.But original design standard, concerning the lilliput car of collision, rigidity is big, is out of shape for a short time, and energy-absorbing effect is poor, the vehicle damage is more serious, if on this basis, continue to improve wave beams rigidity again, this structure guardrail causes difficulty for absorption lilliput car collision energy, therefore, big rigidity wave beams equals to collide the rigid barrier of lilliput car.

The purpose of this utility model provides a kind of wave beams reinforcement guardrail, and it can not only absorb various vehicle collision energies, and can stop the collision vehicle to run off outside the road, crashes to collide, and the occupant damages minimum.

The purpose of this utility model is achieved in that on column, carriage and wave beams bolt together, and the original wave beams steel plate of attenuate thickness is set up reinforced rib (steel rope) device.When the vehicle collision guardrail, it at first collides wave beams, wave beams is stretched the termination up and down toward carriage by the impact force effect just, and motion backward, wave beams and reinforced rib direct contact, because the wave beams of attenuate does not have crossbeam to support, make initial collision quite soft, by the distortion of wave beams, displacement, absorb collision vehicle energy, the collision car retardation is returned to the cruising direction, the lilliput car of collision stops, when heavy-duty vehicle continued to invade guardrail, the wave beams that contacts with reinforced rib distributed impact force to reinforced rib, on carriage and the column, they jointly support a collision of holding up traffic, finally stop up to the collision vehicle, reaching crashes collides, and the occupant damages minimum purpose.

Since adopt such scheme, the steel plate reduced thickness of wave beams, and its stiffness is little, and is yielding, it is effective to absorb collision vehicle energy, simultaneously, sets up reinforced rib, has strengthened the intensity of guardrail, improving crashes collide support resistance, therefore, its crashworthiness is good, so simple in structure; Because the utility model guardrail is selected thin wave beams for use, set up rib device in addition, it is more in light weight than original waveform beam guardrail, saves raw MAT'L, so cost is lower.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a birds-eye view of the present utility model.

Fig. 2 is the front view of Fig. 1.

Fig. 3 is that enlarged drawing is looked on the left side of Fig. 2.

1. columns among the figure: 2. carriage: 3. wave beams: 4. reinforced rib (steel rope): 5.U type rope clamp: 6. gusset.

In Fig. 1, column 1: carriage 2: thin wave beams 3: be linked in sequence with bolt.In the embodiment of Fig. 2 institute, the reinforced rib (steel rope) 4 with two initial tensions is erected on the gusset 6.As strengthen ratiometric Fig. 3 and look, reinforced rib 4 usefulness U type rope clamps 5 are clamped in the structure of side up and down of carriage 2 and gusset 6, reinforced rib 4 it in the center of wave beams 3 circular arcs, when the vehicle collision guardrail, it at first collides yielding wave beams 3, wave beams 3 is subjected to the effect of vehicle collision power, distortion the termination was stretched (this figure draws) toward carriage about in the of 2 when it moved backward, make initial collision quite soft, the wave beams 3 and reinforced rib 4 direct contacts of extensional deformation have been strengthened wave beams 3 intensity, and vehicle collision power distributed to reinforced rib 4, gusset 6, on carriage 2 and the column 1, their shared impact forces of resisting vehicle.

Claims
