Abstract

The invention discloses a highway guardrail with good energy absorption capacity, which comprises an upright column and a guardrail plate arranged on at least one side of the upright column, and is characterized in that a rubber ring obstruction block is fixedly arranged between the upright column and the guardrail plate, a first connecting block is fixedly arranged on the upright column, a second connecting block is fixedly arranged on the guardrail plate, a first lantern ring and a second lantern ring are arranged on the rubber ring obstruction block and symmetrically arranged along the central line of the rubber ring obstruction block, and the rubber ring obstruction block is fixed with the first connecting block through the first lantern ring, and fixed with the second connecting block through the second lantern ring. The highway guardrail has the advantages that the rubber ring obstruction block is arranged between the upright column and the guardrail plate, as rubber has good flexibility and viscoelasticity, and when a vehicle with a certain mass bumps onto the highway guardrail at a certain impact angle at a certain speed, the rubber ring obstruction block can absorb the impact kinetic energy of the vehicle greatly to protect the double corrugated steel sheet from greater deformation, so that the vehicle is guided to the right lane at a smaller angle.

Description

The freeway guardrail that a kind of energy absorption performance is good

Technical field

The present invention relates to a kind of highway barrier, especially relate to the good freeway guardrail of a kind of energy absorption performance.

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 increasingly intensive, and the Global Auto recoverable amount increases substantially year by year simultaneously, and the incidence of traffic accident also is year by year ascendant trend.It is 3 times more than of other type traffic accident on the expressway that the event of clashing into central guardrail 250 times, this class event are approximately arranged on per 200 meters speedways every year on average according to data statistics, 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 large heavy vehicle substantially, but because concrete is done the time spent that deformation occurs is very little bearing external load, therefore 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 subject to is very large, very easily cause the vehicle heavy damage, even cause passenger's injures and deaths; Though semi-rigid corrugated guardrail has good comprehensive mechanical property, the general vehicle collision accident is had preferably resistance and guiding function, but the insufficient strength of corrugated guardrail is large, can not effectively tackle the hot-short of large quality; The flexible cable guardrail is owing to the contact area with vehicle in the knockout process is less, and the finite energy of absorption only has preferably interception and the guide effect to the bump of car.

Summary of the invention

Technical problem to be solved by this invention provides a kind of vehicle that can effectively stop and goes out roadbed or central guardrail and can make vehicle return the good freeway guardrail of energy absorption performance of normal lane with the smaller angle resilience simultaneously.

The present invention solves the problems of the technologies described above the technical scheme that adopts:

The freeway guardrail that a kind of energy absorption performance is good, comprise column and the guardrail board that is arranged at least one side of column, be fixedly installed flexible obstruction block between described column and the guardrail board, described flexible obstruction block is the rubber ring obstruction block, be fixedly installed the first contiguous block on the described column, be fixedly installed the second contiguous block on the described guardrail board, be provided with first collar and second collar on the described rubber ring obstruction block, 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 fixedly connected with described the first contiguous block by described first collar, and described rubber ring obstruction block is fixedly connected with described the second contiguous block by described second collar.

Described rubber ring obstruction block is the annular rubber circle, and described annular rubber circle is horizontally disposed with, and the longitudinal center line of described annular rubber circle is vertical with horizontal plane.

Described rubber ring obstruction block is the annular rubber circle, and described annular rubber circle vertically arranges, and the longitudinal center line of described annular rubber circle is parallel with horizontal plane.The annular rubber coil structures is simple, convenient formation, and the rubber while with low cost is flexible and viscous-elastic behaviour is better, when the Vehicular impact guardrail board, deformation occurs through bump in rubber ring, the part kinetic energy that produces in the time of can absorbing bump, simultaneously rubber ring resilience can be led back automobile normal operation track, and horizontal and vertical arranges equal can playing preferably and acts on, and to be that the obstruction block of rigid structures is compared energy-absorbing effect better with the outside.

Described first collar is identical with the 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 fixedly connected with described the first contiguous block by bolt.First collar is fixed by engaging lug, and it is convenient to install.

Described the first contiguous block comprises the first pedestal and the first fixed head that is arranged on the first base side end face, described the second contiguous block comprises the second pedestal and the second fixed head that is arranged on the second pedestal, described the first fixed head is identical with the structure of described the second fixed head, described the first fixed head is with after described engaging lug is fixedly connected with, form a square through hole between described the first fixed head and described first collar, described rubber ring obstruction block tightly is stuck in the described square through hole.The square through hole that the first fixed head and first set ring form blocks the rubber ring obstruction block tightly, and structure is more firm, and deformation can occur the rubber ring obstruction block to large extent, the kinetic energy that produces in the time of so just absorbing Vehicular impact to large extent.

Described column is cylindrical column, and the end face that described the 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.The first contiguous block is fitted with column and is fixedly connected with, and lifting surface area increases, so that overall structure is more firm.

Compared with prior art, the invention has the advantages that: between column and guardrail board, be provided with the rubber ring obstruction block, 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 larger distortion occuring, and is directed to normal lane with vehicle with smaller angle simultaneously.
