Abstract
A kind of highway barrier, including column (10), undulatory guardrail board (20), the buffering bracket (30) being set between column (10) and guardrail board (20), column (10) outer sheath is set there are one conically shaped (11), and the outer diameter of the conically shaped (11) becomes larger from top to bottom；The buffering bracket (30) is set in the outside of the conically shaped (11) above the conically shaped (11)；The guardrail board (20) is buckled on the buffering bracket (30)；It is characterized in that, the buffering bracket (30) is internally provided with the first spring damping device (4)；The conically shaped (11) is internally provided with second spring damping unit (5).The above-mentioned highway barrier of the utility model provides buffer unit twice, and mechanical impact is effectively relieved, and extends object collision time, to reduce injures and deaths, protects property.
Description
Technical field
It is especially a kind of that there is buffering knot for highway etc the present invention relates to a kind of traffic safety protection technology
The highway barrier of structure.
Background technology
Expressway guardrail mainly uses semi-steel guard bar structure at present, is that one kind is mutually spliced simultaneously with undulatory guardrail board
By the continuous structure of upright supports.When vehicle collides it, since guardrail board has good Impact Resisting Capability and absorbs the work of energy
With being neither easy to be smashed, while can play a very good protection to vehicle and driver and conductor again.The protection of highway barrier is former
Reason is to absorb collision energy using the deformation of soil matrix, column, guardrail board, and errant vehicle is forced to change direction, is returned to just
Normal travel direction prevents vehicle run-off-road, to protect vehicle and passenger, is lost caused by reduction accident.
Chinese patent application CN200480025123.5 discloses a kind of highway barrier, provides made of a kind of rubber
The buffering bracket of elastomer, the elastomer design have up-narrow and down-wide horizontally disposed trapezoid-shaped openings.Since the trapezoid-shaped openings are
A kind of up-narrow and down-wide structure, causes guardrail board earthward to move the purpose that protection is not achieved.
Chinese patent application CN201510216411.9 discloses a kind of highway barrier, provides the buffering knot of conically shaped
Structure removes the connecting component of whole bolts etc, improves the buffering deformation stroke of highway barrier.But for high-speed impact
Vehicle, buffering effect are not still fine.
Invention content
This practicality carries out patent application CN201510216411.9 excellent newly in order to solve defect of the existing technology
Change, a kind of highway barrier with secondary buffer device is provided.
A kind of highway barrier of the utility model, including column, undulatory guardrail board are set to the column and the shield
Buffering bracket between breast board, the column outer sheath are set there are one conically shaped, and the outer diameter of the conically shaped is gradual from top to bottom
Become larger；The buffering bracket is set in the outside of the conically shaped above the conically shaped；The guardrail board is buckled in institute
It states on buffering bracket；It is characterized in that, the buffering bracket is internally provided with the first spring damping device；Inside the conically shaped
It is provided with second spring damping unit.
Preferably, the second spring damping unit is mounted between column and conically shaped, close to road surface position.
Preferably, the damping value of the first spring damping device is more than the damping value of second spring damping unit.
A kind of highway barrier of the utility model is applied to various highways, especially freeway guardrail, uses this patent skill
Art is simple in structure, easy disassembly, and increased two spring damping devices play cushioning effect twice, can effectively absorb and hit
The energy hit reduces injures and deaths, protects guardrail.
Description of the drawings
Fig. 1 is utility model diagram.
Specific implementation mode
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control illustrates this hair
Bright specific implementation mode.
The utility model discloses a kind of highway barriers, as shown in Figure 1, including column 10, undulatory guardrail board 20, if
The buffering bracket 30 being placed between column 10 and guardrail board 20,10 outer sheath of column are set there are one conically shaped 11, conically shaped 11
Outer diameter becomes larger from top to bottom；Buffering bracket 30 is set in the outside of conically shaped 11 from the top of conically shaped 11；Guardrail board 20
It is buckled on buffering bracket 30；Buffering bracket 30 is internally provided with the first spring damping device 4；Conically shaped 11 is internally provided with
Two spring damping devices 5.
Specifically, second spring damping unit 5 is mounted between column 10 and conically shaped 11, close to road surface position；The
One and second spring damping unit select great damping value, separately selected according to the specifically claimed range of highway, still,
The damping value of first spring damping device is greater than the damping value of second spring damping unit.
A kind of highway barrier of the utility model is applied to various highways, especially freeway guardrail, the first and second bullets
Spring damping unit plays cushioning effect twice, can effectively absorb the energy of shock, reduces injures and deaths, protects guardrail.
In a specific embodiment, automobile high-speed hits guardrail, after the first spring damping device 4 receives impact, starts
Compression drives second spring damping unit 5 to start to compress.By spring handle impact energy absorption, then hindered again further through spring
Buddhist nun's device slow release Impact energy ----interior energy is converted mechanical energy into, law of conservation of energy alleviates the shock of machinery, extends
Object collision time protects automobile, the reduction of personnel and guardrail to be hit to reduce the active force generated when collision between object
Hit degree of injury.
Technical staff is appreciated that in the case where not departing from the utility model, it is appropriate to be carried out to disclosed configuration
Adjustment, therefore as described above example be given for example only rather than the purpose of limitation, it will be apparent to those skilled in that recognize
The mesh that small modification reaches identical can be carried out in unobvious change aforesaid operations to configuration or manufacture craft by knowing
, the utility model is restricted by claims.
