CN202298520U - Anti-collision guardrail for road - Google Patents

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

Highway anti-collision guardrail

technical field

The utility model relates to a guardrail, in particular to a highway anti-collision guardrail.

Background technique

The anti-collision barrier is an important part of the safety facilities of the highway, especially the highway. Its function is: 1. To prevent the moving vehicle from rushing out of the road or entering the opposite lane; 2. To reduce the damage of the accident vehicle and the occupant to the minimum.

The current highway crash barriers mainly include rigid guardrails and semi-rigid guardrails. The rigid guardrail is mainly made of concrete guardrail, which is a basically non-deformable guardrail structure. This kind of guardrail has a good effect in preventing vehicles from going out of the road. After the collision, the maintenance of the guardrail is small, but the damage to the vehicle and the danger to personnel are large and the cost is high. High, slow construction speed; semi-rigid guardrail is a continuous beam-type guardrail structure, with a certain degree of rigidity and flexibility, simple construction process, low cost, easy maintenance, is currently the most widely used on roads and expressways kind of guardrail. However, when the traditional beam-type guardrail is subjected to a relatively large impact force, due to insufficient strength and rigidity, the situation of the car going out of the road often occurs, causing relatively large losses.

Contents of the invention

The technical problem to be solved by the utility model is to provide a highway anti-collision guardrail that can enhance the rigidity of the guardrail while ensuring its flexibility.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: a highway anti-collision guardrail, which includes a plurality of uprights arranged at intervals, and guard beams are fixedly connected to both sides of two adjacent uprights.

At least one connecting pipe is fixedly connected between the two parallel protective beams located on both sides of the column.

The connecting pipe is a square pipe or a round pipe, and the connecting pipe and the guard beam are fixedly connected by bolts.

A buffer block is arranged between the guard beam and the column.

Both the guard beam and the buffer block are W-shaped, the guard beam and the buffer block are arranged oppositely, the column is I-shaped, and the gap between the guard beam, the buffer block and the column The connection is fixed by bolts.

Compared with the prior art, the utility model has the advantage that since both sides of the column are connected with guard beams, compared with the traditional beam-type guardrail with only one side guard beam, the overall rigidity of the guardrail is enhanced, and at the same time, the guardrail is guaranteed The local energy absorption effect of the guardrail ensures the flexibility of the guardrail, making the guardrail achieve the effect of both rigidity and flexibility.

Detailed ways

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in the figure, a highway anti-collision barrier includes a plurality of I-shaped columns 1 arranged at intervals, and W-shaped guard beams 2 are arranged on both sides of two adjacent columns 1, and the guard beams 2 and the columns 1 There is a W-shaped buffer block 3 between them, and the guard beam 2 is set opposite to the buffer block 3. The guard beam 2, the buffer block 3 and the column 1 are fixedly connected by bolts 5. A plurality of connecting pipes 4 are fixedly connected between the beams 2, and the connecting pipes 4 and the guard beams 2 are fixedly connected by bolts 5.

In the above embodiments, the connecting pipe 4 may be a square pipe or a round pipe.
