Abstract
The utility model discloses an anti-collision guardrail for a road, which comprises a plurality of stand columns arranged at intervals. The anti-collision guardrail for the road is characterized in that two sides of every two adjacent stand columns are fixedly connected with guard beams. The anti-collision guardrail for the road has the advantages that the two sides of the stand column are both connected with the guard beams. Compared with the traditional beam-type guardrail with the guard beams on one side, the anti-collision guardrail for the road has the characteristics that the integral rigidity of the guardrail is enhanced, meanwhile, the local energy adsorption effect of the guardrail is guaranteed, the flexibility of the guardrail is guaranteed, and the effect that the rigidity and the flexibility of the guardrail are both obtained is achieved.
Description
Technical field
The utility model relates to a kind of guardrail, relates in particular to a kind of highway anti-collision guardrail.
Background technology
Anticollision barrier is the particularly important component part of expressway safety facility of highway, and its effect is: the vehicle in, preventing to advance is run-off-road or drive into the subtend track; Two, make accident vehicle and occupant's injury be reduced to minimum.
Present highway anti-collision guardrail mainly contains two kinds of stiff safety fence and semi-rigidity rails.Stiff safety fence is main with concrete guardrail, is a kind of indeformable basically guard bar structure, and this guardrail prevents that vehicle from running off effective outside the road, and the maintenance capacity of collision back guardrail is little, but to the damage of vehicle and personnel dangerous greatly and cost higher, speed of application is slow; Semi-rigidity rail is a kind of continuous beam type guard bar structure, has certain rigid and flexibility, and construction technology is simple, and cost is lower, and is easy to maintenance, is to adopt the widest a kind of guardrail on present highway and the speedway.But traditional beam type guardrail because the situation that the strength and stiffness deficiency makes automobile run off road happens occasionally, causes bigger loss when bearing bigger impact.
Summary of the invention
The utility model technical problem to be solved provides a kind of rigidity that strengthens guardrail can guarantee the highway anti-collision guardrail that it is flexible again simultaneously.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of highway anti-collision guardrail, comprise the many columns that are provided with at interval, and the both sides of two adjacent root posts are fixedly connected with guard beam.
Between two of the column both sides parallel guard beams, be fixedly connected with at least one tube connector.
Described tube connector is square tube or pipe, is connected through bolt between described tube connector and the described guard beam.
Be provided with buffer stopper between described guard beam and the described column.
Described guard beam and described buffer stopper are W shape, and described guard beam and described buffer stopper are oppositely arranged, and described column is an I shape, are connected through bolt between described guard beam, buffer stopper and the column.
Compared with prior art; The utility model has the advantages that because the both sides of column all are connected with guard beam; Compare with traditional beam type guardrail that has only monolateral guard beam, strengthened the integral rigidity of guardrail, guaranteed the local energy-absorbing effect of guardrail simultaneously again; Promptly guarantee the flexibility of guardrail, made guardrail reach the hard and soft effect that gets both mutually.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, a kind of highway anti-collision guardrail comprises the many columns 1 of the I shapes of setting at interval; The both sides of two adjacent root posts 1 are provided with the guard beam 2 of W shape; Be provided with the buffer stopper 3 of W shape between guard beam 2 and the column 1, guard beam 2 is oppositely arranged with buffer stopper 3, is fixedly connected through bolt 5 between guard beam 2, buffer stopper 3 and the column 1; Between two parallel guard beams 2 of column 1 both sides, be fixedly connected with many tube connectors 4, be fixedly connected through bolt 5 between tube connector 4 and the guard beam 2.
In the foregoing description, tube connector 4 can be square tube or pipe.
