Abstract

The utility model discloses an expressway guardrail with good anti-collision performance. The expressway guardrail with the good anti-collision performance comprises a stand column and a double-wave-shaped guardrail steel plate arranged on at least one side of the stand column. The expressway guardrail with the good anti-collision performance is characterized in that a rubber ring stop prevention block is fixedly arranged between the stand column and the double-wave-shaped guardrail steel plate, the rubber ring stop prevention block is perpendicularly arranged, a first connecting block is fixedly arranged on the stand column, a second connecting block is fixedly arranged on the double-wave-shaped guardrail steel plate, a first lantern ring and a second lantern ring are arranged on the rubber ring stop prevention block, and are symmetrically arranged along the centre line of the rubber ring stop prevention block, the rubber ring stop prevention block is fixed with the first connecting block through the first lantern ring, and the rubber ring stop prevention block is fixed with the second connecting block through the second lantern ring. The expressway guardrail with the good anti-collision performance has the advantages that due to the fact that the rubber ring stop prevention block is arranged between the stand column and the double-wave-shaped guardrail steel plate, when a vehicle with a certain weight impacts the expressway guardrail with the good anti-collision performance at a certain speed and in a certain impact angle, impact kinetic energy of the vehicle can be greatly absorbed, larger deformation of the double-wave-shaped guardrail steel plate is prevented from happening, and the vehicle is guided to a normal lane in a small angle.

Description

A kind of freeway guardrail with good crashworthiness
Technical field
The utility model relates to a kind of highway barrier, especially relates to a kind of freeway guardrail with good crashworthiness.
Background technology
In speedway both sides and central authorities, go out outside the track, place in order to prevent operational vehicle, design and installation freeway guardrail.Build along with speedway, city intersection, elevated road etc. are a large amount of, transportation network is intensive day by day, and global automobile pollution increases substantially year by year simultaneously, and the incidence of traffic accident also is ascendant trend year by year.According to data statistics the event of clashing into central guardrail 250 times is arranged every year on average approximately on per 200 meters speedways, this class event is 3 times more than of other type traffic accident on the expressway, and because of the too hard accident that creates greater casualties of guardrail quite a few.
Existing freeway guardrail mainly is divided into three kinds of rigid concrete guardrail, semi-rigid corrugated guardrail and flexible cable guardrails.From structure and security performance, mainly there is the defective of following several respects in existing freeway guardrail: run off guardrail, can contain effectively that dilly gets out guardrail though concrete guardrail metope formula structure can prevent big heavy vehicle substantially, but because concrete is done the time spent that deformation takes place is very little bearing external load, so the kinetic energy of the vehicle that is absorbed by guardrail in the collision process seldom, the dynamic shearing power that the collision vehicle is subjected to is very big, very easily cause the vehicle heavy damage, even cause passenger's injures and deaths; Though semi-rigid corrugated guardrail has good comprehensive mechanical properties, the general vehicle collision accident is had resistance and guiding function preferably, but the insufficient strength of corrugated guardrail is big, can not effectively tackle the hot-short of big quality; The flexible cable guardrail is because less with the contact area of vehicle in the knockout process, and the finite energy of absorption only has interception and guide effect preferably to the bump of car.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of vehicle that can effectively stop and goes out roadbed or central guardrail and can make vehicle return the freeway guardrail with good crashworthiness in normal track with the smaller angle resilience simultaneously.
The utility model solves the problems of the technologies described above the technical scheme that adopts:
A kind of freeway guardrail with good crashworthiness, comprise column and the double wave shape guardrail steel plate that is arranged at least one side of column, be set with the flexible anti stop block between described column and the double wave shape guardrail steel plate, described flexible anti stop block is the rubber ring obstruction block, described rubber ring obstruction block vertically arranges, and the longitudinal center line of described rubber ring obstruction block is parallel with horizontal plane; Be set with first contiguous block on the described column, be set with second contiguous block on the described double wave shape guardrail steel plate, described rubber ring obstruction block is provided with first collar and second collar, described first collar and second collar are symmetrical arranged along the center line of described rubber ring obstruction block, described rubber ring obstruction block is fixedlyed connected with described first contiguous block by described first collar, and described rubber ring obstruction block is fixedlyed connected with described second contiguous block by described second collar.
Described rubber ring obstruction block is the annular rubber circle.
Described first collar is identical with second thimble structure, and described first collar comprises two engaging lugs, and described two engaging lugs are symmetricly set on the both sides of described first collar, and described engaging lug is fixedlyed connected with described first contiguous block by bolt.
Described first contiguous block comprises first pedestal and first fixed head that is arranged on the first base side end face, described second contiguous block comprises second pedestal and second fixed head that is arranged on second pedestal, described first fixed head is identical with the structure of described second fixed head, described first fixed head is with after described engaging lug is fixedlyed connected, form a square through hole between described first fixed head and described first collar, described rubber ring obstruction block tightly is stuck in the described square through hole.
Described column is cylindrical column, and the end face that described first contiguous block is connected with described column is inner concave, and the circular-arc-shaped exterior contour of described inner concave and described column fits.
Compared with prior art, advantage of the present utility model is: be provided with the rubber ring obstruction block between column and guardrail board, this rubber ring obstruction block is the annular rubber circle, because rubber ring has good flexibility and viscous-elastic behaviour, when the vehicle of certain mass clashes into freeway guardrail with certain speed and angle of impingement, this rubber ring can absorb the bump kinetic energy of vehicle largely, prevents that double wave shape steel plate from bigger distortion taking place, and is directed to normal track with vehicle with smaller angle simultaneously.
