Abstract
The invention provides an anti-collision guardrail of single-beam steel, comprising a single-beam guardrail plate, an assembling plate, a reinforcing steel pipe, an assembling bolt, a protecting block and an upright post. The cross section of the single-beam guardrail plate is in the shape of arc; the upper edge and the lower edge of the guardrail plate are inward and spirally rolled towards the protruding direction of the guardrail plate, so as to form two energy storage rings; through the assembling bolt, the single-beam guardrail plate and the reinforcing steel pipe are connected together, and the assembling plate is arranged between the single-beam guardrail plate and the reinforcing steel pipe. Through the protecting block, the assembled guardrail plate is connected with the guardrail upright post together. When collision happens, the energy storage rings at upper and lower sides of the guardrail plate can be opened; compared with the other anti-collision guardrails, the anti-collision guardrail has better buffer property. Besides, the inner part of the protecting block is hollow; when collision happens, a secondary buffer is carried out, thereby greatly reducing the collision destructive effect.
Description
Technical field
The present invention relates to anti-collision guardrail device field, and in particular to a kind of simple beam steel anti-collision guardrail device.
Background technology
With China's road construction and the fast development of transportation, traffic safety faces severe situation.Anticollision barrier
As safety devices, important function has been played in the traffic safety of protection road and bridge.Generally, anticollision barrier is mainly wrapped
Include stiff safety fence, semi-rigidity rail and flexible safety fence three types；Wherein, stiff safety fence is mainly concrete guardrail, this mixed
Solidifying soil guardrail has excessive rigidity, therefore the ability of buffering and absorption vehicle energy is weaker；When the center of gravity of vehicle it is of a relatively high
When, vehicle easily overturns concrete guardrail after collision concrete guardrail；When the center of gravity of vehicle is relatively low, vehicle is in collision
It is easy to laterally upset after concrete guardrail.Semi-rigidity rail mainly includes wave beam guardrail and beam column guardrail；Wave beam guardrail includes
Double wave guardrail and three ripple guardrails, this corrugated beam barrier absorb vehicle energy by the deformation up and down of steel plate, and this causes
Steel consumption is big and landscape effect is poor.Beam column guardrail is made up of many parallel steel tubes of circular or rectangle, these beam column guardrails
Collision grade is relatively low.
Anticollision barrier for protecting dilly needs flexible design, and the anticollision barrier for protecting oversize vehicle is needed
Want rigid design.The semi-rigid anticollision barrier degree of protection relatively low for oversize vehicle has, and with relatively large
Steel consumption.

The upright setting parallel in the horizontal direction of some columns, is from top to bottom uniformly connected to protection by connecting bolt on the outside of column
Block, protective block are outwards closely fitted with reinforcement steel pipe, assembled plate and simple beam guardrail board successively；The one end for strengthening steel pipe passes through group
, through the reserving hole connection simple beam guardrail board and assembled plate in the middle of simple beam guardrail board, the other end is by assembling spiral shell for dress bolt
It is female to coordinate erection bolt locking protective block；Simple beam guardrail board appearance be in streamlined, its cross section be arcuation, and simple beam shield
The top edge and lower limb of breast board is inwardly spirally crimped towards the projected direction of its own, to be symmetrically formed two energy storage
Ring.
As a kind of preferred technical scheme：The cross section of described simple beam guardrail board is arcuation, and appearance is in streamlined,
With preferable appreciation effect；Two energy storage rings are arranged with lower limb in the top edge of simple beam guardrail board, energy storage ring can
When guardrail is clashed into, to reduce its impact force, when being knocked, can be opened, discharge its strength being subject to, strengthen
The impact force of guardrail；Described simple beam guardrail plate surface is provided with some reserving holes, material saving and good looking appearance；It is described
The distance between neighbouring simple beam guardrail board be more than or equal to 10cm.
As a kind of preferred technical scheme：Described protective block is hollow setting, is set in column outer surface from the bottom to top
3 groups are equipped with, as second energy storage device of guard bar device, when guardrail is clashed into, energy storage ring is not enough to discharge all shocks
During power, energy storage is carried out by protective block, further reduce impulsive force.
As a kind of preferred technical scheme：Described simple beam guardrail board, protective block and assembled plate are metal material
Matter.
As a kind of preferred technical scheme：Described column is class trapezium structure, and upwards, inner side inclines outside upright,
Its slant range is 3%-5%, is conducive to improving stability in the large.
As a kind of preferred technical scheme：Described reinforcement diameter of steel tube is 80-120mm.
The invention has the beneficial effects as follows：（1）When vehicle is collided with simple beam steel anticollision barrier, in vertical direction
On, simple beam guardrail board is firstly broken, and vehicle energy can be buffered and successive elimination；（2）Protection block assembly is carried out again
Buffering, is cooperated with the unification of simple beam guardrail board, and maximum possible must weaken its impact force, and can extend collision time, collision
Extending for time can be to provide good protection for driver and passenger；Compared with prior art, the present invention can be realized more preferably
Buffer capacity and advantage attractive in appearance.
