Description
Technical field
The present invention relates to a kind of highway barrier, especially relate to the freeway guardrail that a kind of energy absorption performance is good.
Background technology
In speedway both sides and central authorities, in order to prevent operational vehicle from going out outside track, place, design and installation freeway guardrail.Along with speedway, city intersection, elevated road etc. are built in a large number, transportation network is increasingly intensive, and Global Auto recoverable amount increases substantially year by year simultaneously, and the incidence of traffic accident is also in ascendant trend year by year.About have the event of clashing into central guardrail for 250 times according in data statistics every year on average every 200 meters of speedways, this kind of event is 3 times more than of other type traffic accident on expressway, and the accident created greater casualties because guardrail is too hard is quite a few.
Existing freeway guardrail is mainly divided into rigid concrete guardrail, semi-rigid corrugated guardrail and flexible cable guardrail three kinds.From structure and security performance, mainly there is the defect of following several respects in existing freeway guardrail: though concrete guardrail wall face-type structural can prevent large heavy vehicle from running off guardrail, can effectively contain that dilly gets out guardrail substantially, but due to concrete, that deformation occurs when bearing external load effect is very little, therefore the kinetic energy of the vehicle absorbed by guardrail in collision process is little, the dynamic shear force that crashing vehicle is subject to is very large, very easily cause vehicle heavy damage, even cause passenger's injures and deaths; Though semi-rigid corrugated guardrail has good comprehensive mechanical property, have general vehicle collision accident and resist preferably and guiding function, but the insufficient strength of corrugated guardrail is large, can not effectively tackle the hot-short of large quality; Flexible cable guardrail is due to less with the contact area of vehicle in knockout process, and the finite energy of absorption, only has interception and guide effect preferably to the shock of car.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of vehicle that can effectively stop and goes out roadbed or central guardrail vehicle can be made simultaneously to return the good freeway guardrail of the energy absorption performance of normal lane with smaller angle resilience.
The present invention solves the problems of the technologies described above adopted technical scheme:
The freeway guardrail that a kind of energy absorption performance is good, comprise column and be arranged on the guardrail board of column at least side, flexible obstruction block is fixedly installed between described column and guardrail board, described flexible obstruction block is rubber ring obstruction block, described column is fixedly installed the first contiguous block, described guardrail board is fixedly installed the second contiguous block, described rubber ring obstruction block is provided with first collar and second collar, the first described 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 the first described contiguous block by the first described collar, described rubber ring obstruction block is fixedly connected with the second described contiguous block by the second described collar.
Described rubber ring obstruction block is annular rubber circle, and described annular rubber circle is horizontally disposed with, the longitudinal center line of described annular rubber circle and horizontal plane.
Described rubber ring obstruction block is annular rubber circle, and described annular rubber circle is vertically arranged, the longitudinal center line of described annular rubber circle and plane-parallel.Annular rubber coil structures is simple, convenient formation, and rubber with low cost while flexible and viscous-elastic behaviour is better, when Vehicular impact guardrail board, deformation is there is in rubber ring through clashing into, the part kinetic energy produced when Absorbable rod clashes into, automobile can lead back to and normally run track by rubber ring resilience simultaneously, and horizontal and vertical arranges and all can play good effect, and compared with the obstruction block being rigid structures with outside, energy-absorbing effect is better.
The first described collar is identical with the second thimble structure, and the first described collar comprises two engaging lugs, and two described engaging lugs are symmetricly set on the both sides of the first described collar, and described engaging lug is fixedly connected with the first described contiguous block by bolt.First collar is fixed by engaging lug, and it is convenient to install.
The first described contiguous block comprises the first pedestal and is arranged on the first fixed head on the first base side end face, the second described contiguous block comprises the second pedestal and is arranged on the second fixed head on the second pedestal, the first described fixed head is identical with the structure of the second described fixed head, after the first described fixed head is fixedly connected with described engaging lug, form a square through hole between the first described fixed head and the first described collar, described rubber ring obstruction block is tightly stuck in described square through hole.Rubber ring obstruction block blocks by square through hole that the first fixed head and first set ring are formed tightly, and structure is more firm, and rubber ring obstruction block to large extent deformation can occur, the kinetic energy produced when so just can absorb Vehicular impact to large extent.
Described column is cylindrical column, and the end face that the first described 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.First contiguous block is fitted with column and is fixedly connected with, and lifting surface area increases, and makes overall structure more firm.
Compared with prior art, the invention has the advantages that: between column and guardrail board, be provided with rubber ring obstruction block, this rubber ring obstruction block is 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 shock kinetic energy of vehicle largely, prevents two corrugated sheet steel from larger distortion occurring, vehicle is directed to normal lane with smaller angle simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail:
Embodiment one: as Fig. 1, shown in Fig. 2, the freeway guardrail that a kind of energy absorption performance is good, comprise column 1 and the guardrail board 2 being arranged on column 1 side, flexible obstruction block is fixedly installed between column 1 and guardrail board 2, this flexible obstruction block 3 is for having the annular rubber circle 3 of centre bore, column 1 is fixedly installed the first contiguous block 4, guardrail board 3 is fixedly installed the second contiguous block 5, annular rubber circle 3 is provided with first collar 6 and second collar 7, first collar 6 and second collar 7 are symmetrical arranged along the center line of annular rubber circle 3, annular rubber circle 3 is fixedly connected with the first contiguous block 4 by first collar 6, annular rubber circle 3 is fixedly connected with the second contiguous block 5 by second collar 7.
In this particular embodiment, annular rubber circle 3 is horizontally disposed with, i.e. the longitudinal center line of this annular rubber circle 3 and horizontal plane.
