Description
Technical field
Road equipment technical field is the utility model is related to, particularly one kind is used for anticollision barrier.
Background technology
With greatly improving for car ownership, safe driving turns into people's moment concern.Particularly at a high speed
The automobile travelled on highway, because speed is very fast, the anticollision barrier positioned at highway both sides then effectively can prevent automobile from sending out
Guardrail is gone out during raw security incident, is provided safeguard to ensure personal safety.The guardrail of traditional highway both sides uses mostly
The column and railing that cement pours or stone is made are assembled, for fixed rigid connection structure, such a guardrail protective capacities
And endurance quality is poor, and without automatic recovery ability, no buffer capacity, when impulsive force is more than its endurance, due to that can not clash
Hit power and produce cushioning effect, it is excessive to inevitably result in rum point periphery local pressure, and ultimately causing rum point, nearby guardrail is serious
Deform or fracture and phenomenon that column is toppled over occurs, cause guardrail local prominent to damage, can only re-replace, safeguard into
This is higher.
The content of the invention
The utility model technical issues that need to address are to provide a kind of anti-with automatic recovery ability and buffer capacity
Guardrail is hit, can be buffered when by impact and weaken Impact energy, is provided to improve safety trip of the automobile in high speed
Ensure.
In order to solve the above technical problems, technical solution adopted in the utility model is as follows.
A kind of arc flake type anticollision barrier, including column and the guardrail that is arranged between adjacent upright posts, the column be
Cylindrical structural, the bottom of column are embedded in roadbed；The guardrail is arc scale baffle plate, arc scale baffle plate and column
It is fixedly connected between top by connecting bolt, connecting bolt is set perpendicular to the inner side arc scale baffle plate end for being close to column
Put；The bent projection portion of the arc scale baffle plate is set towards runway.
Above-mentioned arc flake type anticollision barrier, the column bottom being embedded in roadbed are provided with the transverse slat of setting, and transverse slat is put down
Row is set in runway, and the angle between the connecting bolt and transverse slat in the horizontal plane is 10 ~ 15 °.
Above-mentioned arc flake type anticollision barrier, wear in the connecting bolt between the column and arc scale baffle plate of end
It is connected to termination buffer spring.
Above-mentioned arc flake type anticollision barrier, it has been bolted positioned at the arc scale baffle plate outer end of initiating terminal U-shaped
Originate terminal.
As a result of above technical scheme, technological progress acquired by the utility model is as follows.
The utility model is applied to highway both sides, when impact that can be in the range of by design force value is collided,
Buffer and weaken Impact energy, arc scale baffle plate also can voluntarily recover in the design force value of its permission so that overall shield
Column is stood intact, and Reliable guarantee is provided to improve the safety traffic of automobile on a highway.Connecting bolt is perpendicular to being close to stand
The inner side arc scale baffle plate end set of post, it is excessive with impact angle and roll over for being avoided as much as connecting bolt
Disconnected phenomenon.The termination buffer spring set between terminal column and baffle plate can play final buffering effect, and impact is released
Be put into it is minimum, be effectively ensured installation during, the integrity of guardrail.The U-shaped starting terminal that starting ends are set, can be effective
Arc scale baffle plate end is avoided to wear the generation of the major accidents such as body when accident occurs.The transverse slat that column bottom is set, energy
Enough generations for effectively controlling the phenomenon for causing column to rotate due to powerful impact, it is further the intact of raising guardrail
Property provide guarantee.

Embodiment
The utility model is further elaborated below in conjunction with the drawings and specific embodiments.
A kind of arc flake type anticollision barrier, its structure as depicted in figs. 1 and 2, including some columns 1 and be arranged on it is adjacent
Guardrail between column；Two adjacent columns and the guardrail being connected between this column form an elementary cell.
In the utility model, column 1 is cylindrical structural, and the bottom of column 1 is embedded in roadbed；It is embedded in roadbed
The bottom of column 1 is provided with the transverse slat 5 of setting, and transverse slat 5 is set parallel to runway, in horizontal plane between connecting bolt 4 and transverse slat 5
On angle be 10 ~ 15 °.
Guardrail is arc scale baffle plate 2, is fixed and connected by connecting bolt 4 between arc scale baffle plate and the top of column
Connect, connecting bolt 4 is perpendicular to the end set of inner side arc scale baffle plate 2 for being close to column；Column and arc squama positioned at end
Wear to be connected in connecting bolt 4 between piece baffle plate 2 and terminate buffer spring 6, as shown in Figure 3；Arc scale positioned at initiating terminal is kept off
The outer end of plate 2 has been bolted U-shaped starting terminal 3, as shown in Figure 1.The bent projection portion direction driving of arc scale baffle plate 2
Road is set.
The utility model is installed on highway both sides, when shock accident occurs, if impact is perpendicular to baffle plate,
Be impacted position front end guardrail it is identical with traditional defense structure stress, and the rear end guardrail at the position that is impacted then can will be by
Impact will weaken Impact energy, while arc to next elementary cell transmission, the frictional force of neighboring unit structure junction
The baffle plate of shape scale structure also can buffer portion Impact energy, reach safing purpose；If at impact and baffle plate
When non-perpendicular contact state impingement baffles, arc scale baffle plate can force rum point, and arcuately tangential direction moves, so as to
Play a part of weakening impact, realize the purpose that the impact that will be locally subject to rearward is transmitted successively, meanwhile, arc squama
Piece baffle plate also can voluntarily recover in the design force value of its permission, avoid that permanent damage occurs.
