Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

A road safety guard rail according to an embodiment of the present application will be described with reference to the accompanying drawings.

As shown in fig. 1 to 3, a road safety guard rail according to an embodiment of the present application includes a post 100 and a balustrade panel 200.

It should be noted that the pillars 100 are fixed on both sides of the road at equal intervals, and the balustrade 200 is parallel to and installed between two adjacent pillars 100, when the vehicle collides with the balustrade 200, the balustrade 200 will be bent and deformed to absorb the collision energy and prevent the vehicle from moving out of the road.

Specifically, the bottom of the upright 100 is fixedly connected to a road, and a T-shaped slot 110 is formed above the upright 100, wherein the slot 110 extends along the height direction of the upright 100 and penetrates through the top surface of the upright 100.

It should be noted that the balustrade 200 is clamped in the slot 110 of the upright 100, which facilitates the dismounting, replacement and maintenance of the balustrade 200.

It can be understood that, in order to ensure the firmness of the connection between the breast board 200 and the upright post 100, the slot 100 is provided with the threaded hole 111, the positioning bolt 120 is screwed into the threaded hole 111, and the positioning bolt 120 abuts against the upper side of the breast board 200, so that the breast board 200 can be prevented from sliding out of the slot 110 by the limiting action of the positioning bolt 120.

In the present embodiment, the balustrade 200 is configured as an elongated plate, and the balustrade 200 can be bent and deformed when the vehicle is hit, and both ends of the balustrade 200 in the longitudinal direction are bent inward to form the connecting plate 210.

For example, the connection plates 210 are symmetrically disposed at both sides of the balustrade 200, and the connection plates 210 are inclined toward the outside of the balustrade 200.

In the present embodiment, a T-shaped clip 212 adapted to engage with the slot 110 is formed on the outer side of the connection plate 210, and a reinforcing rib 211 corresponding to the clip 212 is formed on the inner side of the connection plate 210.

Specifically, the clip 212 extends along the width direction of the connecting plate 210, i.e., the extending direction of the clip 212 is perpendicular to the longitudinal direction of the balustrade 200.

Optionally, the clip 212 is integral with the web 210.

Specifically, a reinforcing rib 211 is formed at a side of the coupling plate 210 abutting the balustrade 200, and the reinforcing rib 211 is kept parallel to the chuck 212.

For example, reinforcing rib 211 has a fan shape in cross section, and reinforcing rib 211 and connecting plate 210 are integrally formed.

It can be understood that the structural strength of the collet 212 can be improved by adding the reinforcing rib 211 at a position corresponding to the collet 212 inside the coupling plate 210.

It should be noted that, when the balustrade 200 is impacted by a vehicle on the inner side of the highway, the balustrade 200 can generate bending deformation, and the deformation of the balustrade 200 can pull the connecting plate 210 to swing, so as to increase the bending deformation degree of the balustrade 200, that is, the connecting plate 210 can compensate the deformation of the balustrade 200, so that the balustrade 200 can absorb more impact energy, and further prevent the upright post 100 from inclining due to the pulling of the balustrade 200, thereby finally ensuring the effective height of the balustrade 200 and preventing the vehicle from turning over.

In addition, when the breast board 200 is installed, the chuck 212 is inserted into the slot 110 from the top of the upright 100, and when the chuck 212 descends to the bottom of the slot 110, the positioning bolt 120 is screwed on the threaded hole 111, and the positioning bolt 120 is blocked at the top of the connecting plate 210, so that the breast board 200 is prevented from falling off from the slot 110; similarly, the balustrade 200 can be removed from the slot 110 by unscrewing the positioning bolt 120 from the threaded hole 111.

According to the highway safety protective guard provided by the application, the two longitudinal ends of the breast board 200 are bent inwards to form the connecting plate 210, the clamping heads 212 clamped with the upright posts 100 are constructed on the outer sides of the connecting plate 210, and the reinforcing ribs 211 corresponding to the clamping heads 212 are constructed on the inner sides of the connecting plate 210, so that the connecting plate 210 can increase the bending deformation degree of the breast board 200 after being impacted, further more impact energy is absorbed, and the effective height of the breast board 200 can be ensured.

Although embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present application, and that changes, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art within the scope of the present application.
