detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The object of the present invention is to provide an anti-collision expressway guardrail to solve the problems in the prior art, so that the energy absorption capacity of the expressway guardrail is improved and the safety performance is higher.

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Embodiment one:

As shown in Figures 1 to 4, the present invention provides an anti-collision highway guardrail, including a column 7 and a guardrail panel 2 arranged on one side of the column 7, and the guardrail panel 2 is arranged on the side of the column 7 close to the position of the highway road surface . An energy-absorbing device is arranged between the column 7 and the guardrail 2, and the energy-absorbing device includes a first connecting plate 6, a second connecting plate 3, a rubber ring 5 and a reinforcing collar 4, and the two ends of the rubber ring 5 are flange structures , the flange structure is provided with through holes. The reinforced collar 4 has the same shape as the flange structure, and the position of the through hole on the reinforced collar 4 corresponds to the position of the through hole on the flange structure, and the reinforced collar 4 is set on the inner side of the flange structure of the rubber ring 5 On the circumferential surface of each flange, a reinforcing collar 4 is provided on the inner end surface of each flange. The reinforcing collar 4 is pressed against the flange structure surface of the rubber ring 5 to strengthen the connection strength of the flange structure on the rubber ring 5 . The first connecting plate 6 is fixedly connected to the column 7 ; the second connecting plate 3 is fixedly connected to the guardrail 2 . The flange at one end of the rubber ring 5 is connected to the first connecting plate 6 , and the flange at the other end of the rubber ring 5 is connected to the second connecting plate 3 .

By arranging an energy-absorbing device between the guardrail 2 and the column 7, when the external impact force received by the guardrail 2 is small, the energy-absorbing device mainly absorbs the energy of the impact, effectively protecting the guardrail 2, so that the guardrail 2 is No plastic deformation occurs under small impact force. When the impact force is relatively large, the energy absorbing device and the guardrail board 2 jointly absorb the impact energy, which greatly improves the anti-collision performance of the expressway guardrail.

The end face of the second connecting plate 3 connected to the guardrail 2 is bent, so that one side of the bent part is pressed against the connecting surface of the guardrail 2 .

Guardrail board 2 is metal material, so that can be deformed energy-absorbing.

The outer surface of the guardrail 2 is provided with a plastic layer 1 , and the plastic layer 1 is fixedly connected with the guardrail 2 . The plastic layer 1 is arranged on the outer surface of the guardrail 2, which can effectively reduce scratches and injuries of vehicles or personnel. Due to the addition of flexible plastic, it can also assist the energy-absorbing device to absorb impact energy.

The column 7 is made of cement or steel, and is used to be fixed in the surface soil layer.

The side of the column 7 connected to the energy-absorbing device is a plane, so as to facilitate the connection between the first connecting plate 6 and the column 7 .

Embodiment two:

Other parts are the same as the first embodiment, except that the guardrail 2 and the energy-absorbing device are located on both sides of the column 7, as shown in Fig. 5 and Fig. 6 . In this case, the column 7 is located in the middle of the road, separating the reverse lane.

In the present invention, specific examples have been used to illustrate the principle and implementation of the present invention. The description of the above embodiments is only used to help understand the method and core idea of the present invention; meanwhile, for those of ordinary skill in the art, according to the present invention The idea of the invention will have changes in the specific implementation and scope of application. In summary, the contents of this specification should not be construed as limiting the present invention.
